Xu Xin put the blue crystal into his backpack and swam around looking for similar stones.
Although there are many colorful stones at the bottom of the water, most of them are dull and very turbid, not as clear and transparent as the blue crystal just now. Using identification skills, they all emit white light.
Xu Xin casually took out a purple stone and held it in his hand.
Amethyst (white): An ordinary crystal that can be used for carving.
White grade crystals do not affect the "decorativeness" of the tree house.
Xu Xin threw the crystal away and began to look for crystals emitting green or even blue light under the water.
After swimming underwater for a long time, Xu Xin finally found three green-level crystals of different colors, namely amethyst, red crystal and green crystal. His ability to identify them allowed him to see the light at a glance, and his efficiency was very high.
However, these crystals are not difficult to find for others who do not have the ability to distinguish, because the appearance of the green grade and the white grade is very different. The green grade is clear and transparent, while the white grade is dull and turbid, and they can be easily distinguished.
There were no green-level or higher resources around. Xu Xin emerged from the water and looked at the huge tornado that was only two or three hundred meters away from him.
At such a close distance, the entire tornado looked even more ferocious.
However, perhaps because the tornado had drawn the dark clouds in the nearby sky into it, there were no more thunderstorms nearby. Instead, bright yellow lightning flashed across the tornado from time to time.
"Keke said there is a treasure in the tornado and it is not dangerous. Does that mean she wants me to go in? But how dare I go in..." Xu Xin muttered to himself as he looked at the oppressive tornado in front of him.
Entering this tornado? What's the difference between that and seeking death...
However, although the distance was only a few hundred meters, Xu Xin still did not feel any suction from the tornado. Only the water where he was was flowing in the direction of the tornado.
The entire nearby water area was rotating along with the tornado.
Diving back into the water and looking in the direction of the tornado, Xu Xin was surprised to find that the underwater part of the tornado in the distance was actually just a small underwater whirlpool!
Of course, this smallness is compared with the above-water part of the tornado.
The thinnest part below the water part has a diameter of several dozen meters, and it becomes increasingly larger as it goes up into the sky. The position of the clouds can even affect an area of thousands of meters in radius, making the entire tornado appear very exaggerated.
But there seemed to be only a whirlpool with a diameter of about ten meters underwater. There seemed to be something in the whirlpool rotating with the water flow, but it was not clear.
The vortex speed is not fast, at least much slower than the wind speed on the water surface.
Xu Xin thought he could get closer to take a look.
But before that, he had to discuss with the explorers to see if he could get some information that he didn't know.
There was no place to stand nearby, so Xu Xin had to float to the surface and open his watch.
Ji Chaoyang: "If you are good at swimming, you can try to get closer to this tornado. There must be some new materials around the tornado that we have never seen before. I am afraid they will be related to our survival in the next stage."
Ji Chaoyang said this right after Xu Xin came down from the tree house. He didn't say anything after that. He must have gone out to explore.
Xu Xin couldn't help but sigh at his good luck. If he hadn't obtained this set of anaconda scale armor, he wouldn't even be qualified to go out and explore.
With his swimming skills that took him more than a minute to swim 50 meters and left him breathless, he could only wait in the tree house until the activity was over.
Qi Xuefei: "Come on, I'll be waiting for you in the tree house."
Wang Lei: "This... Does being able to doggy paddle count as being able to swim? Forget it, I'd better just walk around the tree house. If I go too far, I'm afraid I won't be able to swim back..."
Li Wenxi: "I'd better stay in the tree house too. This activity is really not friendly to people who can't swim."
Wen Guixin: "I'll go out and take a look. My skills are pretty good. If there are any new resources, I'll tell you."
Zhao Xiaochuan: "I'll go check it out too. There's a reservoir near my home. Before I came to this world, I often swam in the reservoir. I'm not afraid of reservoirs that are dozens of meters deep, so four or five meters is nothing!"
Zhao Xiaochuan's words seemed to show off his ability to swim, but Xu Xin could see that he was more of a cheer for himself. After all, the shape of the tornado outside was indeed too intimidating.
Qin Yunlong and Qin Yunhu remained silent. These two were good swimmers and, probably like Xu Xin, they had already started exploring in the water.
Li Wenxi also sent him several private messages.
"Xu Xin, what do you think? Can that tornado really get close?"
"But I'm not a very good swimmer. The distance over there is more than one kilometer. I definitely can't swim over there. It doesn't matter to me whether I can get close or not..."
"Have you gone out yet?"
This message was sent nearly half an hour ago.
Xu Xin replied: "I am only two or three hundred meters away from the tornado."
Li Wenxi was playing with her mutant cow in the tree house out of boredom. When she saw Xu Xin's reply, her eyes widened: "You are so close! Two or three hundred meters away, won't you be sucked in?"
"No, but the water currents near the tornado are constantly rotating. If you are not a good swimmer, don't come over here, as you may be swept in directly."
"Well, have you discovered any new resources?"
"Indeed, I will tell you when I get back."
"Oh ok, be careful!"
While Xu Xin was communicating with Li Wenxi in private, he carefully looked at the nearby tornado. At this time, some things were still flying out of the tornado from time to time, mostly some stones, wood, and some beast corpses.
Xu Xin sent messages to Qin Yunlong and Ji Chaoyang again, wanting to exchange information with them, but no one replied to him.
… Their exploration progress might not be as good as his own. It seemed that he could only rely on himself.
Suddenly, a long piece of wood thrown out from the tornado hit a place not far from Xu Xin, splashing huge water, and then floated out of the water, turning with the water flow.
Xu Xin swam over immediately.
He discovered that this wood was different from any wood he had seen before. It was darker in color and the texture in the cross section looked more regular.
Hugging the driftwood, Xu Xin breathed a sigh of relief and relaxed his body. Finally, he could take a short break.
This piece of redwood is equivalent to the trunk of a tree and is much larger than ordinary lumber, logs and logs.
Redwood (green): A high-grade wood with tough wood, fine texture and bright color. It is a superior material for carving and can be used to make furniture to enhance the decoration of the tree house.
It’s the degree of decoration again!
Although lying on the redwood would allow him to rest, he would be drawn closer to the tornado as the water flowed. So Xu Xin collected the redwood and let it float in the same place.
There were many floating redwoods on the surrounding water, rotating with the current, probably thrown out by the tornado.
Whenever these logs came nearby, Xu Xin would swam over and put them into his backpack. Before long, he had collected twelve redwoods.
Xu Xin felt that it was enough, and he planned to go to the center of the tornado to take a look.
Waterweed (blue) would provide the ability to breathe underwater for half an hour, and he ate it with the blessing of the dining table, so it lasted for forty-five minutes, but even so, the effect had long since worn off.
Xu Xin replenished the effects on his body, dived into the water again, and swam towards the whirlpool in the center.
As he got closer to the underwater whirlpool, Xu Xin found that the pulling force of the surrounding water was getting stronger and stronger. When the distance was less than 100 meters, his body began to be involuntarily carried around in circles by the water.
Xu Xin stopped his movements and let the water flow carry him towards the center.
The rotation speed was not fast and he could completely control his body in the water.
Suddenly, a familiar sense of crisis slowly rose in his heart, causing his relaxed body to suddenly tense up.
Xu Xin looked around nervously, looking for the source of danger.
The water is still very calm, the water is rotating along with the vortex in the center, and the stones on the bottom of the water are also rotating with the water and are gradually being sucked into the vortex in the center.
As he got closer to the vortex in the center where his interior could not be seen, the sense of crisis in his heart became stronger and stronger.
The danger indeed comes from the whirlpool!
Just as he was staring at the whirlpool, ripples suddenly appeared on the whirlpool which was originally rotating calmly. Then, a big fish with a length of nearly four meters suddenly emerged from the whirlpool!
The spikes on its mouth were extremely sharp, like a sharp sword, pointing straight towards Xu Xin!
