Yuan Xu took Yuan Tan and Wei Qi to the cave where he had advanced first.

He took out three glow sticks from his backpack and handed them one to each of them.

Yuan Tan and Wei Qi got the glow stick and looked at him with a confused expression.

"It's called a glow stick." Yuan Xu said: "It's dark in the cave, and you need to use it for lighting. ”

He took the glow stick and folded it hard, and the stick lit up.

Yuan Tan and Wei Qi followed his example and brightened up the glow sticks.

They went into the cave.

When I walked into the cave, I was greeted by a cold breath.

Yuan Tan found that there was a sticky liquid on the cave wall.

He asked Yuan Xu: "Why are the cave walls here so sticky?" ”

"Because this is where I slay my dragon." Yuan Xu replied: "The slime on the cave wall is what it left behind. ”

Yuan Tan hurriedly withdrew his hand and subconsciously swallowed his saliva.

The further you go into the cave, the darker it becomes.

Wei Qi said: "Fortunately, there is a glow stick given by Gongzi, otherwise he really looks like a blind man." ”

Yuan Xu didn't say anything, only Yuan Tan echoed from the side.

Towards the end, they saw the light.

"Why is it that at the end, there is a light?" Yuan Tan asked in surprise.

"There's a hole in the hole." Yuan Xu said: "That's where the light comes in. ”

When they came to the place where there was a waterhole, Yuan Tan and Wei Qi really saw a big hole open in the top of their heads.

"Childe is the dragon you slay here?" Seeing the waterhole, Wei Qi asked.

"I don't think it's a dragon." Yuan Xu replied: "At most, it's just a Jiao. ”

After Jiao soars, it is a dragon, such a divine thing, let alone slaughter by ordinary people, even if they want to get close, it is difficult.

"What did Xianxin bring us here for?" Yuan Tan asked, "Is it just to let us see the place where Jiao is slaughtered?" ”

"Of course not." Yuan Xu said: "The place where Tujiao is not beautiful, I want to ask you, how about building an ice cave here?" ”

"The cave is a natural thing, and it would be great if we could build an ice cave here." Wei Qi replied: "It's just that what method does Childe want to use?" After all, the ice cave is colder than here. ”

"Cold belongs to yin, yin is enough, there is still a way." Yuan Xu took out the ghost qin and stroked the strings gently.

He decided to build an ice cave, which was indeed very risky, after all, necromancy did not have that function.

The strings vibrate, and the magic sound appears.

Of course, Yuan Tan and Wei Qi couldn't see the magic sound.

Sitting behind the ghost qin, Yuan Xu looked at the magic sound: "You should know what happened to me?" ”

"Necromancy can indeed make this an ice cave." The magic voice replied: "It's just that the lord can't leave anymore, and as soon as the lord leaves, the ice cave will naturally die." ”

"That's not going to work." Yuan Xu pouted: "I don't want to be a compressor for the refrigerator." ”

"If the lord doesn't want to do that, there is a way." Demon Yin said, "The second-level summoning technique is available. ”

"Level 2 summoning?" Yuan Xu asked in surprise, "How to use it?" ”

"The lord's understanding of the future generations should be no less than mine." Moyin asked, "I don't know if you remember, what is the extremely low temperature, and it can even affect the surrounding area?" ”

"Dry ice, liquid nitrogen, and so on." Yuan Xu's eyes lit up first, and then he said with some loss: "Those things are stored in containers, and the containers have the effect of heat insulation, once they are opened, they ......."

"If this place is completely cordoned off......" Demonic Voice looked around.

Yuan Xu immediately understood.

The cave is very effective at storing temperature, and if you can completely seal it off and get some dry ice or liquid nitrogen, it will be easy to release the corresponding amount when it is opened every once in a while, and the waterhole will probably be frozen as well.

"I see." Yuan Xu nodded: "You go first." ”

The magic sound subsided.

In Yuan Tan and Wei Qi's opinion, Yuan Xu just sat there and didn't say anything.

The two of them didn't know what he had summoned, and they didn't dare to disturb.

After the magic sound retreated, Yuan Xu said to them, "I already know what to do. ”

"What are Childe's plans?" Wei Qi asked.

"Let's get this place completely sealed off first." Yuan Xu said: "The big hole at the top must be filled first, and then two doors will be built in the passage, so that I can use magic to turn this place into an ice cave." ”

"I'll do it." Yuan Tan agreed, turned around and wanted to go out.

Yuan Xu stopped him and instructed Wei Qi: "You go and do it!" ”

Wei Qi left, and Yuan Tan's face was embarrassed.

To fill the cave, Yuan Xu has refused to use him, and he will only be able to do a few things by Yuan Xu's side in the future.

"I remember telling my eldest brother." Yuan Xu said to Yuan Tan: "Follow me, you just need to watch, all things don't need to be done." ”

"I am glad to see that I have the ability." Yuan Tan replied: "I always hope to do something." ”

"When I calm down the world, the eldest brother still has nothing to do?" Yuan Xu asked him.

Yuan Tan replied: "Of course I'm not afraid, but I think that if I can't fight the world with Xianxin, what qualifications will I have to sit in the world together in the future?" ”

"What the eldest brother said is also reasonable." Yuan Xu smiled indifferently: "But to fight the world, you don't need a few brothers, or even a million troops." ”

"I understand what Xianxin said." Yuan Tan said: "There are countless murderous corpses at every turn, dare to ask who in the world can compete?" But ......"

"Nothing." Yuan Xu interrupted him: "I just think that the brothers of the Yuan family have been fighting each other for too long, and this battle should have ended a long time ago." The best way to end the fight is for the brothers to have no more military power. Without military power, even if you want to fight, you don't have the strength. ”

Yuan Xu was not pretentious at all, and he couldn't have made what he said very clearly.

Yuan Tan, who had already understood, said to him: "I have written down everything Xianxin said. ”

"Of course it's great that my brother can write it down." Yuan Xu replied.

A moment later, Wei Qi, who had come out of the cave, walked back.

When he arrived in front of Yuan Xu, he bowed down and said, "Childe, I have instructed the guards to fill it, and it won't take long for them to reach the top of the cave." ”

Yuan Xu nodded: "It can be the best." ”

Sure enough, after waiting for a short time, some shaking shadows appeared overhead.

The guards had reached the top of the cave.

They first found some trees and used them to make beams, and then they spread earth and stones on them.

Yuan Xu raised his head and looked at the top of the cave that was being sealed.

Yuan Tan asked, "Will it be useful to seal it like this?" ”

"It stands to reason that it should work." Yuan Xu replied: "It's just that it has to be paved thicker, and the roof of the cave is just sealed with mud, and it still can't hold the air conditioning." ”

"What are Childe's plans?" Wei Qi asked.

"You go out again, and tell the guards to use more mud on it." Yuan Xu explained: "Wait until it is completely sealed, and then light a fire on it, burn the soil into pottery, and the air conditioner can be held." ”
