Sun Bin and Hua Mulan and his party continued to go north. They walked for three days without encountering anything. However, as you head north, the climate gets colder and colder.

"Why did I go for three days and three nights, and the trace of the demon clan is gone." Hua Qilin Road.

"That's true, there isn't even a single demon in the sky who is scouting and patrolling." Xiaozi echoed.

"Maybe the rest of the demons are not in the north, but in the east." He Guozhong said.

"According to our teacher's observation for many years, most of the demons are in the north. During this season, it is snowy in the north, and they rarely come out to move. Sun Bin said.

"Brother Sun, the snow is falling in this northern land, and there are no fruits, vegetables and grains, what kind of food do they live on?" Hua Mulan asked Sun Bin beside her.

"The demons were originally native to Proxima Centauri, and unlike us humans, we can't use a general point of view to figure them out. Plants can synthesize nutrients to supply themselves in the environment of light, air and water, which is called photosynthesis. Now I believe more and more that the demons themselves also have a light and function, and they use their green skin to absorb light, air and water to complete the light and effect, and produce organic matter and energy. Sun Bin spoke eloquently.

When everyone heard this, they were all amazed.

"I never thought they would be so weird. No wonder I see them coming out during the day and rarely going out at night. Mulan said with emotion.

"We shouldn't take it lightly at night, after all, after the demons got the fragmentary Heavenly Book, they evolved extremely quickly, and they may also be able to use starlight for light and effect, but the efficiency is slightly inferior to that of the day." Sun Bin said.

"Then we shouldn't call them demons, we should call them vegetatives." He Guozhong quipped.

When everyone heard this, they smiled.

"This is just my inference, and this investigation is to verify that it is conjecture." Sun Bin said.

"Look ahead, it looks like a demon." Lu Ban said suddenly, he took out the polar eyepiece again and looked carefully. "There are probably dozens of demon caves in front, and between each demon cave, the demons are bustling back and forth, some are holding arrows, some are carrying sharp knives, and there must be a place where they cast weapons."

"We'll camp here and look at it in the evening." Mulan Road.

The group nodded in agreement and began to set up tents in the lower depressions, covering the outside of the tent with a layer of snow to hide the traces of the tent. When the sun set in the west and the starlight was filled, everyone began to carefully approach the casting place of the demons.

"There's the smell of charcoal burning here, but where did they get their casting skills from?" He Guozhong was puzzled.

"Even if the demons have the Book of Heaven, it is impossible for them to smelt iron alone and forge various weapons, and there must be the guidance of the human race." Luban Road.

"How can this be justified, let me catch him, I must abolish him." Hua Qilin Road.

"Captain, there are no guards patrolling outside the cave, so let's go into the cave and take a look." Xiaozi Road.

Mulan hesitated for a moment and said, "It's okay." ”

"I'll go with you." Zhong Wuyan said.

Later, Hua Mulan took Xiaozi and Zhong Wuyan and went into the cave to investigate. The rest of the people waited not far from the cave and kept an eye on the situation at the entrance to the cave.

However, it didn't take long for the three of Mulan to return to everyone.

"Why did you come back so soon? What's going on inside? Hua Qilin asked curiously.

"Each demon cave is not very deep, and the contents inside can be seen clearly through the starlight. There are several large caves inhabited by demons, and the rest of the caves are all kinds of weapons, no worse than those cast by our human race. Moreover, there are several caves dedicated to iron ore and furnaces. Xiao Zi said.

"Liu Chunfeng, immediately record the terrain and specific conditions of the demon clan at the moment." Mulan Road.

"Okay, Captain." Xiao Zi took out a pen and paper from his waist, and began to draw seriously with the light of the night pearl in Hua Qilin's hand.

"Captain, why don't we take advantage of the fact that the demons are sleeping and give them results one by one." Hua Qilin Road.

"No, some demons have a very sensitive sense of hearing, and if they wake up, the consequences will be unimaginable. In the future, the further north we go, the more cautious we must be and not act recklessly. "Mulan Road.

"Mulan is right, be careful to make the Ten Thousand Year Ship." Zhong Wuyan said.

"I haven't asked you yet, what's your name, and what you're responsible for in the North?" Sun Wukong asked with his hand, picking up the big ears of the pig.

"Big brother, the younger brother is called Zhu Gangguan, nicknamed Bajie, he is responsible for catching fish and picking fruits in the north, and now the snow is everywhere, so he should be the messenger." Pig Gang grinned and grinned.

"Big brother? Big brother, is it also your green pig barking? Don't say it, you're quite good at making friends. Sun Wukong joked.

"It's a must, big brother, don't talk about big brother, just call grandpa." Pig Gang continued to grin.

"Go, is my grandson so old! My grandson remembers that when I was in the north, there was very little snow, almost all year round, there were all kinds of melons, fruits, pears and peaches, how could it be as snowy as today? Sun Wukong asked.

"Our king said that it was the Terrans who wantonly exploited the resources of our Proxima Centauri, which made the Creator so sad and angry that it snowed heavily in the sky. But our military advisors say that it is the radiation effect of humanity's ark of tomorrow that causes climate change. Pig Gang said.

"Then now that the snow is sealed, don't the demons have to turn on their own light and function?" Monkey King said.

"Who's to say it's not, but the more light and action we make, the greener our skin becomes, you can see from me. But eventually we will turn black and lose the ability to photosynthesize. Therefore, our military advisors have been studying pills day and night that can inhibit skin darkening. But our king—" said Pig Gang.

"But your king wants to kill all the Terrans and regain control of Proxima Centauri, right?"

"Hee-hee, that's right." Pig Gang Chiena.

Sun Wukong flew up with a kick, the pig just fell to the ground in the air, and the dust in the courtyard rose all over the sky.

"For the sake of himself, he can kill other creatures in vain, and the reason is so high-sounding. His Bull Demon King's heart, isn't it clear to my grandson? For its own purposes, it can orchestrate and fabricate evidence of anyone's crimes. Why are you still lying on the ground, pretending to be dead? Be careful that my grandson cuts off your ears for a snack. Sun Wukong said angrily.

When the pig heard this, he suddenly got up from the ground.

"Brother Monkey, you're right, he is the Bull Demon King is a wolf ambition, I will definitely peel off his skin for you when I have a chance in the future, and remove his tendons to relieve your hatred back then." Pig Gang grinned and laughed.

"What are you doing standing here stupidly, hurry up and sweep the courtyard for my master, leaving a fallen leaf, and my grandson just flew up with one foot." Monkey King said.

"Brother Monkey, you can do it, I'll go now, and in the future, just call me Bajie, so it looks kind." Zhu Bajie said.
