Just when he was about to say something else, Li Wenxi suddenly spoke in the group.

"Everyone, I found saltpeter, we can make ice!"

More than two hours have passed since Xu Xin made the deal with her. It seems that she has contracted a mutant beast and returned to the tree house.

Li Wenxi's words immediately diverted the attention of the group.

Wen Guixin: "Saltpeter? That saltpeter that can make ice?! Wen Xi, I want it, sell it to me, sell it to me, and I'll trade it with you for blue-level resources!"

Ji Chaoyang: "Did you find a lot? If not, we can use it in turns. Saltpeter can be used repeatedly for making ice. A small part can meet the needs of many people."

Qin Yunlong: "Is that the saltpeter that is the raw material of black gunpowder?"

Wang Lei: "It should be so, but there is no sulfur, so we can't make gunpowder."

Qi Xuefei: "Do I have a share? Many medicines also need to be stored at low temperatures."

Li Wenxi: "Everyone has a share. However, after I mined all the saltpeter, I only have less than a hundred kilograms. If you want it, I can only sell you ten kilograms each, and I have to keep some for myself."

It seems that she still knew how to hide it, and did not say what she said to him, "In short, it is enough." However, the saltpeter was weighed by the pound, and it seemed that she just wanted to provide green grade saltpeter.

The group was very lively, and everyone was asking Li Wenxi about saltpeter, but Xu Xin was not interested. He had blue-grade saltpeter, which was enough for refrigeration.

However, he was a little curious about whether Li Wenxi's contract with the mutant beast went smoothly, so he directly sent a private message and asked: "What animal did you contract with?"

Li Wenxi was busy negotiating the price with others and did not reply to him. After half a day, she 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. The cow's hair is now covered with blood-red patterns.

Being large is normal. Large herbivores are generally larger than carnivores.

The largest bison species on earth, the Ganges bison, can easily weigh more than a thousand kilograms, and can even weigh a meal and a half. Moreover, the body fat content of cattle is very low, and they are full of muscles. They are very strong. If they collide,

It's very powerful.

The disadvantage is that it is very cumbersome. An unarmed matador can use only a piece of red cloth to trick a cow until it hits the wall. Therefore, if it is a contract fighter, Xu Xin would still prefer cats or bears, who are natural hunters. Cows are used as pack animals.

Stuff or plowing would be better.

"Look, I listened to you and contracted a cow! You can ride it and carry a backpack, and it's much faster than walking by myself. It's so powerful!" Li Wenxi looked very excited at this time, and was very excited about her.

The cow was very satisfied.

"Congratulations! Huh? This is a cow. Why didn't you contract a bull? It should be stronger." Xu Xin observed the cow.

He only gave Li Wenxi a bottle of medicine. In other words, the cow only used one bottle of medicine to successfully mutate. It seems that beings like the Silver King who consume a lot of medicine are indeed rare.

"I can't afford to mess with a bull, okay? Those horns are really scary." Li Wenxi touched the cow's back, spread her hands and said, "I raided this cow when it was alone. The cow was also

It's good, maybe you can drink milk in the future. By the way, has your refrigerator been finished?"

Xu Xin told Li Wenxi how she used blue-grade saltpeter to make an ice cellar, and told her to collect more mutated animal meat for storage after making the ice cellar, otherwise it might not be available in three days.

"Ice cellar, okay, I'll try it now!" Li Wenxi was eager to try.

After hanging up the video, Xu Xin looked at the [Explorers] group. Everyone had bought saltpeter from Li Wenxi and were discussing how to make a refrigerator.

Xu Xin decided to explain to them about the mutated animal meat.

He told them directly and clearly that mutated beast meat does have the effect of improving strength, but it is relatively weak and requires long-term consumption to be effective, so he suggested that they also stock up on more mutated meat.

He did not tell this group of people how he knew, which may have something to do with his ability.

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 period after coming out of the dungeon, he renovated the treehouse, installed lightning rods, solved the piranha problem, obtained a purple-level suit, explored the giant cave in the middle of the lake, and established a top-level plantation and a bottom-level

icehouse.

He really did a lot of things in one night and one day, which directly stretched his survivability to the max.

Tomorrow is the rainy season for the new event. I hope all his efforts are not in vain.

After washing up, Xu Xin carried Coco to his bedroom. In the bedroom, she also made a basin of ice for cooling, spread his cotton mattress on it, and made a quilt, and lay down comfortably.

On the bed.

You know, turning on the air conditioner and covering yourself with a quilt is much more comfortable than sleeping without a quilt in the summer.

I hope tomorrow's activities can be simpler.

Touching the little guy on the pillow, he gradually fell asleep.

…

Valley invasion

Xu Xin was awakened by a thunder.

He had never heard such loud thunder in his life. The huge thunder seemed to explode above his head, causing him to jump out of bed with a look of surprise on his face.

"Hey!" Keke was so frightened that she jumped up and turned somersaults, then climbed onto Xu Xin's shoulders and looked out the window warily.

Xu Xin also looked out the window.

It was after six o'clock in the morning. If it were normal, the sun would have already shone into the house, but it was very dark outside at this time, and it felt completely cloudy.

Xu Xin got up from the bed and looked outside. The sky was filled with darkness, and gray-black clouds were connected in patches, extending to the horizon. They were extremely thick and huge, covering the entire sky.

Each dark cloud seemed like a mountain peak towering in the sky, hanging in the sky like Buddha's Five Fingers Mountain. This oppressive feeling made Xu Xin's breathing become heavy.

This thundercloud is really low, so low that it makes him feel very close!

Although it was very dark outside and there were thick clouds in the sky, it was not raining at this time, but the air became very humid. There was a very uncomfortable feeling of humidity when you breathed it in, and the surrounding air seemed to have become thicker.

Xu Xin found that the quilt he had just put on yesterday felt wet to the touch.

"This is a bit uncomfortable." Xu Xin felt that her body was all wet, and now she just wanted to take a shower.

Pushing open the bedroom door, Yinwang and Mimi had already woken up. They must have been awakened by the deafening thunder just now.

Suddenly, a flash of light flashed out of the window, and an extremely thick bolt of lightning pierced the sky. Just when Xu Xin's expression changed and he wanted to cover his ears, the deafening thunder sounded again, which made him still a little stunned when he had just woken up.

My confused mind suddenly sobered up.

"Is this lightning so close?" Xu Xin was surprised.

The lightning outside just now was very close to him, almost striking in front of his eyes. The huge and thick lightning was so spectacular that although it was only for a moment, it lingered in Xu Xin's mind.

Perhaps vision deceives him, but hearing does not.

The interval between when he saw the white light and when he heard the thunder was only one second, or even less. Calculated based on the speed of sound, the lightning was only more than three hundred meters away from him.

!

You know, thunder comes from the clouds. In other words, the distance between the dark clouds above the head and the tree house is only more than three hundred meters! This is too low!

Generally cumulonimbus clouds are also very low, and can be as low as about 600 meters, but 300 meters is a bit too much. Such a low cloud has such a strong sense of pressure that it even makes people feel like it will fall directly!

Moreover, the thunder was so loud that it made his head buzz.

Another bolt of lightning flashed across, and Xu Xin subconsciously covered her ears.

This time Xu Xin consciously counted the seconds, but within a second, the thunderous thunder sounded again, causing the entire jungle to jump up and down, and countless animals fled in a hurry.

"It's just thunder but no rain?"

That's right, although the gray-black thunderclouds in the sky were very thick, the surrounding air was very humid, and the thunder had sounded twice, there was still not a single drop of rain falling.

Another bolt of lightning flashed across, and this time before Xu Xin could react, a loud bang suddenly came from above his tree house, followed by thunder.

What's going on?!

Xu Xin felt like he had reached the top floor. Through the glass on the ceiling, he could see some 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 treehouse was struck by lightning!

In the next two minutes, five more lightning bolts struck down, three of which struck the lightning rod.

This black lightning rod made of black gold was arcing at this time. The black needle body glowed with a faint white light after absorbing the lightning. As the number of lightning strikes increased, the light on the black gold lightning rod became brighter and brighter.

"What about charging?" Xu Xin understood. The lightning rod can provide power to the tree house, and the bright light on it may represent the amount of power.

As for why most of the lightning struck his tree house, it is easy to explain, because his tree house is the tallest tree nearby, and there is also a lightning rod that can attract lightning. It is difficult for the lightning not to strike him.

.

Xu Xin suddenly thought that in the last event, the reward for the returnees was to raise the tree house by one floor.

Even a low tree house will become one of the tallest trees in the jungle after being raised one storey, and I'm afraid it will be targeted by lightning!

Good guy, even the rewards for the event are full of traps!
