Just when he was about to say something, Li Wenxi suddenly spoke in the group.
"Everyone, I found saltpeter, we can make ice!"
More than two hours had passed since Xu Xin had made the deal with her. It seemed that she should have already contracted a mutant beast and returned to the tree house.
Li Wenxi's words immediately diverted the group's attention.
Wen Guixin: "Saltpeter? The saltpeter that can make ice?! Wen Xi, I want it, sell it to me, sell it to me, I will exchange it with you for blue-level resources!"
Ji Chaoyang: "Did you find much? If not much, we can use them in turns. Saltpeter can be used repeatedly to make ice. A small amount can meet the needs of many people."
Qin Yunlong: "Is it the saltpeter, the raw material of black powder?"
Wang Lei: "That should be the case, but without sulfur, we can't make gunpowder."
Qi Xuefei: "Do I have a share? Many medicines also need to be kept at low temperatures."
Li Wenxi: "Everyone has a share, but even if I mine all the saltpeter, there is still less than 100 kilograms. If you want it, I can only sell you 10 kilograms each, and I have to keep some for myself."
It seems that she still knew how to hide it and did not say to him "Anyway, it's enough". However, the saltpeter was measured by pound, so it seems that she only wanted to provide green-grade saltpeter.
The group was very lively, and everyone was asking Li Wenxi about saltpeter. However, Xu Xin was not interested. He had blue-grade saltpeter, which was more than enough for refrigeration purposes only.
However, he was somewhat curious about whether Li Wenxi's contract with the mutant beast was successful, so he sent a private message directly asking, "What animal did you contract with?"
Li Wenxi was busy negotiating the price with other people and did not reply to him. Half a day later, he suddenly called Xu Xin via video.
Behind her in the video is a mutated bison that is several times larger than the mutated Silver King Mimi, and its fur is now covered with blood-red patterns.
It is normal to be big; large herbivores are generally larger than carnivores.
The largest species of bison on earth, the Gangetic bison, can easily weigh more than a thousand kilograms, and the largest can even weigh up to a ton and a half. Moreover, the body fat content of the cattle is very low, and the whole body is full of muscles. The strength is very great, and if it collides, the power is very huge.
The disadvantage is that they are very bulky. An unarmed bullfighter can use just a piece of red cloth to make a bull run into a wall. So if he wants to contract a thug, Xu Xin would prefer a natural hunter like a cat or a bear. Cows are better for carrying things or plowing the fields.
"Look, I listened to you and contracted a cow! I can ride it and carry a backpack. It's much faster than I can walk by myself. It's so powerful!" Li Wenxi looked very excited and was very satisfied with her cow.
"Congratulations! Hmm? This is a cow. Why don't you contract a bull? It should be stronger." Xu Xin observed the cow.
He only gave Li Wenxi one bottle of potion, which means that the cow successfully mutated using only one bottle of potion. It seems that existence like the Silver King that requires a large amount of potion is indeed rare.
"I can't afford to offend a bull. Its horns are really scary." Li Wenxi touched the bull's back and spread his hands. "I attacked this bull when it was alone. A female cow is also good. Maybe I can drink milk from it in the future. By the way, is your refrigerator ready?"
Xu Xin told Li Wenxi how he used blue-grade saltpeter to make an ice cellar, and told her to collect more mutant animal meat for storage after the ice cellar was built, otherwise it might be gone in three days.
"Ice cellar? Okay, I'll go try it now!" Li Wenxi was eager to try.
After hanging up the video, Xu Xin looked at the group of explorers. Everyone had already bought saltpeter from Li Wenxi and was discussing how to make a refrigerator.
Xu Xin decided to explain the matter of the mutant beast meat to them.
He told them directly and clearly that mutant beast meat did have the effect of improving strength, but it was relatively weak and would only be effective after long-term consumption, so he suggested that they stock up on more mutant meat.
He didn't tell the group how he knew it, which might have something to do with his abilities.
As for whether these people listen to him or not, that is their business.
After finishing everything, the day is coming to an end.
During the time after coming out of the dungeon, he renovated the tree house, installed a lightning rod, solved the problem of piranhas, obtained a purple-level suit, explored the giant cave in the center of the lake, and built a plantation on the top floor and an ice cellar on the bottom floor.
He did a lot of things during this night and day, which directly pushed his survival ability to the maximum.
Tomorrow is the new event, Rainy Season. I hope all his efforts will not be in vain.
After washing up, Xu Xin carried Coco to his bedroom, made a basin of ice in the bedroom to cool down, spread his cotton mattress, made a quilt, and lay down on the bed comfortably.
Xu Xin was awakened by a thunder.
He had never heard such a loud thunder in his life. This huge thunder seemed to explode above his head, and it made him jump up from the bed with a look of surprise.
"Oh my god!" Coco was so scared that she jumped up and somersaulted, then climbed onto Xu Xin's shoulder and looked out the window vigilantly.
Xu Xin also looked out the window.
It was a little after six in the morning. If it were a normal day, the sunlight would have already shone into the house, but it was very gloomy outside, and it felt like a completely cloudy day.
Xu Xin got up from the bed and looked outside. The sky was pitch black. Gray-black clouds were connected together and extended to the horizon. They were extremely thick and huge, covering the entire sky.
Each dark cloud seemed like a mountain towering in the sky, hanging in the air like Buddha's Five Finger Mountain. This oppressive feeling made Xu Xin's breathing become heavy.
The thunderclouds were really low, so low that they seemed very close to him!
Although it was dark outside and the sky was covered with dark clouds, it was not raining at this time. It was just that the air became very humid, and there was an uncomfortable feeling of dampness when breathing. The air around seemed to become sticky.
Xu Xin discovered that the quilt he had just changed yesterday now felt wet.
"This is a bit uncomfortable." Xu Xin felt his body was wet and now he just wanted to take a shower.
When I pushed open the bedroom door, Yin Wang and Mimi had already woken up. They were probably woken up by the deafening thunder just now.
Suddenly, there was a flash of light outside the window, and an extremely thick bolt of lightning streaked across the sky. Just as Xu Xin's face changed and he wanted to cover his ears, deafening thunder sounded again, instantly clearing up his head, which had just woken up and was still a little confused.
"Is the lightning so close?" Xu Xin was surprised.
The lightning outside just now was very close to him, almost striking right in front of his eyes. The huge and thick lightning was extremely spectacular. Although it only lasted for a moment, it lingered in Xu Xin's mind.
Perhaps vision deceives him, but hearing does not.
From the time he saw the white light to the time he heard the thunder, the interval was only one second, or even less. According to the speed of sound, the lightning was only more than 300 meters away from him!
You know, the thunder comes from the clouds, which means that the distance between the dark clouds above and the tree house is no more than 300 meters! This is too low!
Normal cumulonimbus clouds are also very low, as low as around 600 meters, but 300 meters is a bit too much. Such a low cloud is too oppressive, and it even makes people feel like it will fall directly!
Moreover, the thunder was so loud that it made his head buzz.
Another flash of lightning flashed by, and Xu Xin subconsciously covered his ears.
This time Xu Xin counted consciously, but after just one second, the deafening thunder sounded again, causing the entire jungle to become chaotic, with countless animals fleeing in panic.
"Thunder without rain?"
That's right, although the gray-black thunderclouds in the sky were very thick, the surrounding air was very humid, and thunder had already sounded twice, there was still not a single raindrop falling.
Another flash of lightning flashed across the sky, and this time before Xu Xin could react, a loud bang suddenly came from above his tree house, followed by thunder rolling in.
What happened?!
Xu Xin felt like he had run to the top floor. Through the glass on the ceiling, he could see some electric arcs lingering on the lightning rod he had placed on the top floor. After a few seconds, the arcs slowly disappeared.
The lightning rod absorbed the lightning!
His tree house was struck by lightning!
In the next two minutes, five more bolts of lightning struck, three of which hit the lightning rod.
This black lightning rod made of black gold was now surrounded by arcs. After absorbing the lightning, the black needle body emitted a faint white light, and as the number of lightning strikes increased, the light on the black gold lightning rod became brighter and brighter.
"This is, charging?" Xu Xin understood. The lightning rod can provide electricity for the tree house, and the light on it may represent the amount of electricity.
As for why most of the lightning struck his tree house, this is easy to explain, because his tree house is the tallest tree in the vicinity, and there is also a lightning rod that can attract lightning, so it is difficult for the lightning not to strike him.
Xu Xin suddenly remembered that in the last event, the reward for those who returned was to make the tree house higher by one floor.
Even a low tree house, after being raised by one floor, will become one of the tallest trees in the jungle, and it will probably be targeted by lightning!
My goodness, even the rewards for the event are full of traps!
Moreover, most of the explorers have more advanced tree houses, and even if they don’t raise this floor, it will probably attract lightning!
