A moment later, all the remains of the mechanical lifeforms on the ground were picked up by Xia Yu.

Xia Yu also carried his unchanged backpack back to the middle of the pentagonal formation.

9S, who was full of curiosity, looked at the backpack Xia Yu was carrying on his back, wanted to speak and stopped, stopped talking and desired, thought for a while, and decided to speak.

"My lord, the wreckage you just put in your backpack?"

"That's what you say." Xia Yu shrugged his shoulders and showed off the light backpack, "Isn't it common sense that materials can fit into the backpack?" You don't even understand this, do you? ”

"Ah......h

Is this common sense? I couldn't read it, but I was blown away.

9S was shocked, 9S began to think, 9S felt that his system was starting to overheat, and 9S's head was starting to smoke!

Boom! 9S stopped thinking.

"9S, are you alright?"

2B on the side saw that 9S suddenly began to stagger, as if he was about to fall, and hurriedly stepped forward to support the other party, 9S held his head and shook his head, exhaling a breath of white steam.

"I'm fine, 2B, it's just that the system suddenly heated up, and now the temperature has come down."

After recovering, 9S turned his head and looked at Xia Yu with a wistful expression, even if he didn't take off the tactical eyepiece, Xia Yu could still imagine the sparkling eyes behind the eyepiece.

"It's amazing, my lord, please tell me more common sense!"

Xia Yu: "......"

How stupid is this kid.

After thinking about it, Xia Yu decided to do a wave of popular science for 9S, and he was idle anyway.

"The materials you pick up can not only be put into a backpack, but also can be put together into new things anytime and anywhere, and when a human is injured, as long as you take a secret medicine called a blood bottle, you can fully recover from the injury, by the way, the blood bottle must be eaten directly, and you can't leave the glass bottle containing the secret medicine alone."

"Can humans eat glass bottles?" 9S looked shocked.

"Of course, human beings can not only eat glass bottles, but also eat all kinds of minerals, otherwise how do you think the various minerals in the human body come from, they are all eaten one bite at a time."

9S：(°Д°)

"By the way, the minerals you eat can't be left for too long, it's best to just dig them out of the ground, so fresh, and the taste is the best, if the minerals are in contact with the air for too long, they will deteriorate."

Hearing these "common sense", 9S looked entangled, and said with some unconfidence: "But the book doesn't write about the common sense you said......

"Hey, you unlucky kid, I'm serious...... Ahem, seriously give you science popularization, you still still don't believe me, do you believe in the words in the book that can be changed at any time, or do you believe in me, a living human being. ”

Listening to Xia Yu's questioning words, 9S's face was distorted, he thought about it, and finally decided to give up everything he knew from the book, what the adult said was right, the adult is a living human being, and he can't be fooled!

"I choose to trust my lord!" 9S said seriously.

"Okay, you can teach, since you are so studious, then I will tell you about the common sense of human beings."

Next, Xia Yu walked towards the interior of the forest, while giving the 9S science popularization of human knowledge to the people around him, like when something falls from the sky, as long as you put a bucket of water below it in time to avoid falling damage, and it is possible to get a hatched chick directly by throwing the egg to the ground......

These common sense listen to the 9S from time to time to let out exclamations, and even 2B and A2 are frequently sideways.

Only Bobola and Divara looked helpless when they heard it, they were one of the artificial human machines that existed before the extinction of human beings, so they naturally heard the flickering in Xia Yu's words.

But looking at the eloquent appearance of the human adults, the twins rationally chose to be silent, as long as the human adults are happy, even if the stupid boy named 9S is fooled and lame, it is none of their business.

That's right, it's all for the sake of human adults, and it's not like they want to have fun.

In this way, under Xia Yu's common sense popularization, the three parasitic artificial people were amazed from time to time, and the twins laughed silently, and the group soon came to the middle of the forest.

In the middle of the forest, there is a natural square, and there are buildings left over from the old era of human beings, although they are covered with moss, but the buildings do not look like they have collapsed and weathered.

At this moment, the square is filled with several rows of mechanical lifeforms, and there is a special individual standing on the building that seems to be an instructor.

"They, are they practicing?"

Behind the roots of the tree, 9S looked at the picture transmitted back by the auxiliary machine and was shocked, the mechanical lifeforms in the picture actually practiced their marksmanship with the beat.

Although those few spear skills are extremely simple, they reveal a very amazing news, mechanical lifeforms have actually produced wisdom!

This is something that their cyborgs can't imagine at all, and in their idea of cyborgs, mechanical lifeforms are just simple machines.

The only reason why they can put their androids at a disadvantage in the war is that there are too many mechanical lifeforms, and the mass-produced mechanical lifeforms all exist in billions.

But now, it would not be good news for these special individuals to develop wisdom like them.

"My lord, please let us go and deal with these mechanical lifeforms!"

After watching the information sent back by the auxiliary machine, 2B said to Xia Yu seriously.

"Alright, the three of you go together, don't chop those mechanical lifeforms too much, Bobora and Divara will be here to protect me."

When the twins on the side heard this, they took a step forward at the same time and nodded firmly, indicating that they would definitely protect the human adults.

The three white-haired androids gave a military salute to Xia Yu and ran towards the forest square.

"They can be dangerous, 2B, please don't be careless!" On the way there, 9S said to 2B beside him.

"That's what I'm going to say, be careful, Nai...... Now. 2B responded quickly.

"Huh!!" 9S suddenly turned his head in surprise, looked at 2B and asked, "What did you just say?" ”

"Be careful, 9S."

"Huh? No way? The pronunciation is closer to "Ness", right? ”

"Advance quietly and hit the enemy."

"Damn!"

Looking at the interactive 9S and 2B, a person's A2 feels sour in his mouth for some reason.

"Cut!"

A2, who silently sped up, clenched the sword in her hand, and she wanted to vent this inexplicable unhappiness on the damn mechanical lifeform.

On the other side, behind the roots.

Bobora and Divara glanced at each other, and for the sake of the reputation of the human adults, they decided to go beyond it a little and give the human adults a wake-up call.

"Human, the common sense you said earlier may cause them to misunderstand, and if they react, it will affect your reputation." Bobora spoke.

"That's right, human lords, if you let them know that you're fooling them, your image may be skewed in their minds." Divara spoke.

"I thought something was wrong." Hearing the twins' reminder, Xia Yu waved his hand nonchalantly and said, "Anyway, I didn't say that all the common sense is correct, and they themselves have to believe it, no wonder me." ”

"Besides." Xia Yu suddenly looked at the twins with a smile on the corner of his mouth, "Isn't there still you, if they react, for the sake of my reputation, it's up to you to explain." ”

Rely on us...... Humanity depends on us!

At this moment, the twins' system instantly heated up, and the mood of cheering and excitement was constantly refreshed, and they glanced at each other and said in a firm tone.

"Don't worry, Human, we won't let your reputation be damaged!"
