Both of them had serious expressions.
"No, this may not be the entrance to the underground world." Xu Xin's increased mental power allowed him to keep his mind clear at all times. He thought for a moment and said, "Perhaps, it is just the iron passage door commonly used by the Blood Mark Clan in this world. It may just lead to a certain underground city."
It's not impossible.
Although they have only seen this kind of iron door at the entrance to the underground world, it does not mean that this kind of door is only used at the entrance to the underground world.
Ji Chaoyang nodded slowly, and reached for the handle of the iron door, but stopped in mid-air, a little hesitant: "Do you want to open it?"
If it really looks like the entrance to the underground world, then underneath the iron gate, there is most likely thick red fog.
Will the red mist affect the surrounding stone statues
"Coco, is there any danger down there?" Xu Xin asked Coco, who had just recovered and stopped trembling in his arms.
"Hmm." Coco shook its little head, indicating that it couldn't feel anything.
Is there no danger
"It's all dug out, let's open it." Xu Xin said, gritting his teeth.
It can't be all in vain.
Ji Chaoyang nodded, grabbed the door handle and was about to open it.
Just at the moment of pulling, his expression changed and he suddenly pulled his hand back.
"What's wrong?" Xu Xin reached for his backpack vigilantly.
Once a situation arises, he can take out his weapon and attack at the first moment.
"… This door cannot be opened for the time being. Besides, the temperature is too low." Ji Chaoyang frowned and spoke with clenched fists.
He slowly opened his slightly trembling hands, only to see that a small part of the skin on the palm of his hand had been torn off by the cold subway handle. The wound was indeed colorless and pale, and had been directly frostbitten and cracked.
What a severe frostbite!
Just a scratch, that's it?!
This iron gate is so cold!
You know, Ji Chaoyang was wearing a snow fox scarf, so fifty degrees below zero was just a normal temperature for him.
It freezes like this when touched, this temperature...
One or two hundred degrees minus
Absolute zero is only -273.15℃...
However, if this iron gate is so cold, why doesn’t the coldness radiate outwards
"How about using a weapon to pry it open?" Xu Xin suggested.
Ji Chaoyang stood up and said, "No, I was just informed that this entrance is temporarily closed."
"Entrance?" Xu Xin's eyes trembled, "What entrance?"
"I don't know," Ji Chaoyang shook his head. "That's all I can say. Or, you can touch the door handle. Although it will get frostbitten, you have the ability to identify things, so you should be able to get more information than me."
As he said this, he took out two blue-level hemostatic herbs from his backpack, picked up two stones and began to polish them.
This injury is not enough to waste pills, but the injury on the hand will affect all aspects of the body, so it is still necessary to recover.
“… Grind some for me too.” Xu Xin said to Ji Chaoyang.
Indeed, he should see it himself.
"Why do you think I took out two hemostatic herbs?" Ji Chaoyang smiled.
"… "
Xu Xin did not reach out to grab it directly, but first gently touched the door handle with his fingers.
Although it was very cold, icy cold, it was just ordinary icy cold.
Not cold anymore
He reached out and grabbed the door handle, pulling it upwards with force.
"Ying!" While pulling, Coco suddenly cried out in his arms. It was a warning cry when she sensed danger!
The rusty iron door did not move, but a bone-chilling chill instantly rushed into his hand from the door handle!
His Tong Kong suddenly shrank, and he immediately let go, quickly retracted his right hand, and stood up.
The palm of my hand felt a piercing pain for the first moment, and then I instantly lost consciousness, as if I had been anesthetized.
This entrance is temporarily closed and can only be opened after the teleportation array is activated.
"Hmm..." Coco looked at the palm of his hand, called out weakly, and licked it with her little tongue.
"... After activating the teleportation formation, this entrance can be entered." Xu Xin's palms were numb. Even when Coco licked him with her warm and soft little tongue, he could not feel any touch.
He lowered his head and looked at the rusty iron gate again.
The temperature of the iron door itself is very normal and can be touched at will, but once you pull the iron door to open it, a chill will immediately surge out that humans cannot bear.
"Didn't you mention the entrance in your introduction?" Ji Chaoyang handed him the ground hemostatic herb.
"No."
After Xu Xin applied the herbal medicine, his injuries recovered at a speed visible to the naked eye, and the sensation in his palms also gradually recovered.
"Then there's nothing we can do." Ji Chaoyang clenched his fists. His injuries had also recovered. "It seems that we can only continue exploring after the teleportation formation is opened."
Xu Xin nodded.
He had no idea what was underneath, but it might be related to the stone statues and the long seal. Adding to Coco's reaction just now, there might be something very dangerous under the iron door.
All this can only be done after the teleportation array is opened.
The two continued to walk around the group of stone statues on the top of the mountain, occasionally touching these stone statues with exaggerated and ferocious movements.
The sunlight at this time was very bright, and shining on the stone statues at the top of the peak gave it a strange beauty.
Until they walked back to the center of the giant peak and back to the portal, the two did not discover anything.
Coco also nestled comfortably in Xu Xin's arms and didn't notice anything unusual.
"It seems that we can't find anything at this time." Xu Xin looked up at the pterosaur with its wings spread out, as if it was about to soar into the sky again. "Let's go back. Maybe we can come back and take a look in the evening."
They calculated that the evening was the time when these stone statues might change.
"No." Ji Chaoyang shook his head. "Let's wait for Lou Fei'er to climb up and activate the Snow Mountain Formation. We should not create unnecessary trouble. What if these stone statues really come alive..."
Xu Xin nodded slowly: "That's right. As for other matters, let's at least wait until the formation is activated."
The two were teleported down from the snowy mountain.
Xu Xin looked at the watch. It was already eleven o'clock in the morning. He didn't know what stage Lou Feier had reached in her climb.
“Hmm…” Coco raised her little head and looked towards the snow-capped mountains with a blank gaze, not knowing what she was looking at.
After returning to the tree house, Ji Chaoyang was teleported directly back to his own tree house.
When Xu Xin returned to the third floor of the tree house, Coco immediately crawled out from the snow fox scarf, jumped onto the sofa and rolled around. He also released the three beasts.
He planned to make art, but before that, there was one thing he had to deal with.
It’s the big banyan tree in his bracelet.
He sent a message to Qi Xuefei: "Has Ji Chaoyang told you about the banyan tree? I have a banyan tree here that can be transplanted."
After a few seconds, Qi Xuefei replied: "Ji Chaoyang told me, is this one for me?"
"Yes, I'll go over now."
After saying that, Xu Xin opened the portal and teleported to Qi Xuefei's tree house.
There are now three parasitic tree houses around her tree house, all of which are low, two-story tree houses.
The sound of the portal condensing at the exit was so loud that everyone in the three tree houses leaned out to look.
"It's Master Xu Xin!"
"Master Xu!"
The two newcomers immediately became excited when they saw Xu Xin and waved to him.
"Hello." Xu Xin nodded at them, and Qi Xuefei also swung down from the tree house.
Xu Xin told her how to use the banyan tree and helped her plant it next to the tree house.
The grown banyan tree merged with the tree house within a few minutes, expanding the space of Qi Xuefei's tree house by one or two floors.
However, unlike Xu Xin and Ji Chaoyang, her banyan tree only expanded the space of the first and second floors of the tree house by 50 square meters, not 100 square meters. It seems that the space initially expanded by the banyan tree is also related to the level of the tree house itself.
However, fifty meters is enough. Each floor of her blue-level tree house originally had fifty square meters, and now with the banyan tree, each floor has a total of one hundred square meters.
The maximum area of each functional area can reach 80 square meters, which means that the area of her drug cultivation room can be expanded.
Qi Xuefei also figured out the reason, with a happy expression on her face: "Thank you, not only do we have more decorations, but we also have a larger area. With the addition of two new people, the output of raw materials for medicinal materials can even be increased several times. According to estimates, it should not be a problem to supply the entire area with low-level pills."
At present, Qi Xuefei has been selling low-level healing pills on the world trading platform and regional trading platforms. These are the kind of healing pills with relatively strong side effects. However, most of them are in short supply and are sold out instantly once they are put on the shelves.
"For advanced pills, perhaps we can try to increase production and supply them to the outside world."
Now, her advanced pills are only supplied to the explorers.
Xu Xin shook his head and said, "Don't sell high-level pills to ordinary survivors. You can use them to trade with the strong people in other areas, especially those in Area 1. I believe that even if you ask for a lot, they will definitely buy it, and there will definitely be some unexpected gains."
Advanced pills are basically equivalent to a life.
Although they do have no shortage of explorers.
When Li Wenxi got up that day, she felt unwell, so Xu Xin directly gave her a high-grade pill.
Qi Xuefei was stunned for a moment, then smiled and shook her head: "Your ideas are basically the same as Ji Chaoyang's. He also advised me not to sell it to other people, not even to people in this area, otherwise it will easily flow into the world market and reduce its value."
"So what do you think..."
"At present, high-level pills cannot be mass-produced. I just said that we can try to increase production, but if that happens, the output of low-level pills will be greatly affected." Qi Xuefei explained, "We should still give priority to allowing people in this area and ordinary people in other areas to use low-level pills. As for high-level pills, you are right, they should indeed be used as a bargaining chip."
Qi Xuefei's philosophy of saving lives influenced her actions, and she has been selling pills to the outside world.
But Xu Xin didn't say anything, this was her own ability.
Moreover, she doesn't give them away for free. The price she sells the low-level pills on the world channel is very high. In short, it is very reasonable.
"By the way, what's the situation with your brother?" Xu Xin thought of Qi Zixuan, the person they had not found yet.
Qi Xuefei's eyes wavered slightly: "He hasn't contacted me for a long time. He didn't reply to my messages. He refused to accept my offers to trade with him. I don't know what happened to him."
"... As long as he's not dead, it's fine. When we find him, we'll bring him to you." Xu Xin didn't know what to say, so he could only say it casually.
"Well, it would be great if we could find him."
After saying goodbye to Qi Xuefei, Xu Xin activated the portal and returned to his tree house.
It's time for lunch.
After tasting Lou Feier's cooking, he was very disgusted with his own cooking. He just ate a few bites and went to the art room to start his art creation.
Today's increase in mental strength was a perfect match for artistic creation. He carved eighteen small statues in a row this morning, and he didn't feel tired or exhausted at all.
He picked up the paintbrush and soon, one painting after another was created by his hands.
Koko had crawled onto his lap again at some point and was watching him paint obediently.
The time spent on artistic creation always passes quickly.
Looking at the sixty green-level paintings in front of him, Xu Xin nodded with satisfaction.
Most of these paintings are landscapes.
Although mass-produced art may be of a lower quality, its function is the same, adding ten points of decoration.
He called Ma Hongwei and the call was answered quickly.
"Brother Xin, what's the matter?"
"What are you doing?" Xu Xin had always forgotten to contact him and had also forgotten to bring him into the Explorer, which must have made him feel a little embarrassed.
"I'm researching a new heavy crossbow. However, its current decoration level is too low and the efficiency of my R&D department is pitifully low." Ma Hongwei said with a hint of helplessness.
Xu Xin directly traded ten paintings to him.
"What the hell!" The other party was shocked. "This, this, this... Ten paintings add 100 points of decoration?!"
"There will be more in the future. Okay, just continue your research."
"Okay!"
Then, he initiated transactions with Ji Chaoyang, Li Wenxi, and Qi Xuefei, offering each of them ten paintings.
Qi Xuefei accepted it instantly and thanked him.
Ji Chaoyang and Li Wenxi were both outside at this time.
Ji Chaoyang didn’t know where to explore again, so he replied with a thank you.
Li Wenxi found a mine cave halfway up a hill that was not buried by snow, and led everyone to go mining.
This time she didn't send a video, she didn't like videos when she was mining. But she still sent a voice message, saying that she would receive it after returning to the tree house.
"I don't know. Fei'er has climbed to that position now."
"Her conditions are better than mine, don't worry."
After hanging up the call, Xu Xin looked at the sky outside.
It is now three o'clock in the afternoon. According to his calculations, Lou Feier should be about to pass through, or has already passed through, that extremely cold section and is about to reach the middle of the snow-capped peak.
I hope she doesn't encounter any special situations.
Xu Xin walked into the art room again and continued to carve and paint.
He planned to use today's time, taking advantage of his increased mental strength, to upgrade the decoration level of all the explorers.
Small carvings and paintings were created by him at a rapid speed.
Time passed quickly, and the sky outside gradually darkened.
Xu Xin put down the carving knife, looked at the dozens of small carvings, and stretched.
After creating so many works, his artist proficiency still hasn’t improved…
He also thought that after his proficiency improved, he would start making blue-level decorations.
"Ying!" Coco, who had been lying on the window at some point, suddenly stood up and shouted toward the window.
"What's wrong, Coco? Is there anyone outside?" Xu Xin stood up and walked over.
Suddenly, a voice was heard outside the tree house.
"Xu Xin, Master, are you there? I'm back!"
Um
It’s Lou Feier!
Xu Xin immediately looked out the window and saw Lou Feier, who was fully armed, standing under the tree house. When she saw him sticking his head out, she immediately waved, "I succeeded! I climbed up there and saw that you were not there, so I teleported down directly to find you!"
It's only a little after five o'clock, how come it's so fast
Seven hours?!
He glanced at the rankings, and sure enough, the eighth person already appeared on the list.
⑧Lou Feier District 187
The leaderboard did not show Area 188, but Area 187, where her main tree house belonged.
Wow, District 187 is going to be popular!
This is the fourth area after Area 188, Area 1, and Area 23 where a survivor has reached the top!
