Du Kang took Xiao Xuan, who was a little tired, and went straight back to the hotel, then took out his mobile phone and carefully checked the substitute task.

[Congratulations on finding an urgent substitute mission, come and pick it up~]

[Urgent recruitment of emergency substitutes: one construction worker, daily settlement, salary negotiable]

[Requirements: Proficient in AI-related programming techniques and able to apply them.] 】

Do you want to take this task?] Yes / No]

Du Kang was stunned for a moment, only to feel that three question marks seemed to appear on his forehead.

"Programming techniques related to artificial intelligence? What does this have to do with construction workers, and who needs to be able to program artificial intelligence? Even if it is, where will it be used, will it be used for smart home? ”

It's no wonder that Du Kang is so puzzled, these two are logically incompatible, and at most, designers in the construction industry need to use computer graphics. And isn't it ancient times that you're going to go, where did programming come from?

Du Kang was a little hesitant to take on this task now, if he really wanted AI programming, he knew six out of seven, and he didn't know anything, if he didn't meet the requirements of the task, what would be the consequences?

"Let me think about it......" Du Kang selectively ignored Xiao Xuan, who had come back from "playing" and eating, took out his mobile phone and started the game, and began to think about and analyze it seriously.

Anyway, don't worry about cats and cats are short-sighted, cats don't have to go to school, and there are people to take care of, just play casually.

"The first possibility is that when I substitute for work, I can not only go to the ancients, but also to the future? If it's the future, with the current involution, it seems that there will be no problem for future construction workers to be able to program AI or something.

If that's the case, then it's useless for me to learn it even if I'm cramming it now, and by then the computer language and algorithms will definitely be updated a lot, I don't know to what extent, but there is definitely a high probability that I will do useless work, with my IQ, it's a big deal to wait until then I start learning.

The second possibility, which is still ancient, is just that the system deliberately translated it into another way. If I remember correctly, the system itself likes to translate the ancient profession into the modern profession, and the ancient construction workers were related to AI programming...... What could that be? ”

Du Kang still couldn't figure it out thoroughly, but when he thought of this, it would have been fine, and when the temporary cramming was destined to have no effect, it was better not to hug it, and go directly to see it, wouldn't it be happy to see the move?

With such thoughts, Du Kang and Xiao Xuan said that they wanted to take a nap, and when they heard that Xiao Xuan, who had already begun to indulge in games, did not raise his head in response, he changed his clothes and lay on the bed, and the curtains were automatically drawn until they were tightly closed.

……

"Keep it up! Come! ”

"Whew!"

"Hah!"

Before Du Kang opened his eyes, the sound of shouting and cheering in unison came into his ears, and the momentum was not very large, because it was not neat, but there were many voices intertwined...... But in the end, it gives people a feeling of being in full swing.

After opening his eyes, Du Kang finally knew why this movement was made.

Countless stones, pieces of green bricks were carried by the people with burdens, pulled by ropes to go to the place where it should go, and were neatly piled up in their rightful places, and sweat dripped down, or penetrated into them, or evaporated by the scorching sun...... Eventually, one of the greatest wonders in human history will be formed.

It is a building that will spread over the ridge, and there will be no end in sight.

Great Wall.

The Great Wall under construction!

Looking at it, Du Kang even had a feeling of numbness on his scalp.

This is one of the highest crystallization of human ability and ingenuity, and in ancient times, when productivity was low, the amount of manpower and material resources required to build such a spectacle would be an unimaginable astronomical amount...... However, nature also has its own necessary reasons.

"When did I come here?"

Du Kang came back to his senses, looked left and right, and found that he was on a small hill, and there was no one else beside him.

Speaking of the Great Wall, probably the first thing that many people think of is the Qin Dynasty to build the Great Wall, but in fact, since the beginning of the Qin Dynasty, the Han, Northern Wei, Sui and Tang dynasties, the Song Dynasty, the Ming Dynasty and other dynasties have built the Great Wall, but the length, location, and materials built in different periods are different.

Therefore, Du Kang did not know the dynasty he was in now when he saw the Great Wall, with such a long time span, how could he know which dynasty he was seeing in front of him at a glance?

And...... There is one more problem.

Substitute class, I am here to substitute for the class, what about the person who makes himself substitute? Why didn't you see a shadow?

No one saw it, how could the salary be negotiated, could it be that it was among this group of people who built the Great Wall?

"No, it's impossible, if it were, then I wouldn't ask for any AI programming technology......" Du Kang frowned, and suddenly a thought flashed through his mind, and he entered the land without the slightest hindrance, and it was his Earth Movement Five Elements PLUS version that he had performed.

It is probably impossible to ask those people, and it is easy to scare others, and the estimate of the officers is about the same.

And those who have read Journey to the West know that if you don't decide to stomp your feet, the old man of the land or the mountain god should come out...... However, Du Kang, who also worked on behalf of the land, would definitely not do that, so he chose to visit more politely.

Immortals such as land and mountain gods, as long as they are not in the time when the aura is cut off or in troubled times, are basically everywhere, and they belong to the category of finding a designated one. For Du Kang, it is even easier to find, the spiritual fusion of the leylines, the spiritual consciousness is everywhere, and everything is hidden.

It's just that the observed situation made Du Kang couldn't help frowning.

……

In the small land dwelling, a smell of blood overflowed, so thick that it made people feel a little uncomfortable.

No one knows why the landowners like to live in such a residence, maybe it may be some kind of conventional hobby or hard and fast rules?

"Shangxian, come, use some medicine?"

“…… Can't you use spells to stop bleeding? ”

"The little god is just a land lord, where did he get so much incense for this kind of spell to learn ......"

"Okay...... That's tiring, thank you...... Hiss! ”

"Shangxian, bear with it, this medicine is a good medicine, it is easy to hurt, but the wound will heal quickly after the pain is over."

"Hmm...... The bleeding did stop...... What is this medicine? I don't think I've ever seen it. ”

"It's that once the little god saved a person, he gave it to the little god, saying that it was a hemostatic dispersion, but it was only effective for the flesh to stop bleeding and scarring, and the little god was a spirit body, and then it has been saved, speaking of which, if there is no this, the immortal will be dangerous this time, and it can be seen that the fate of the world is wonderful......"

"Hemostasis and dispersion...... How could it be this color? I remember it seems to be brown and yellow, why is it black from your Excellency? ”

"Eh, Shangxian is really well-informed, so speaking of which, at the beginning, this hemostatic powder was indeed brown and yellow, yes, why has it turned black now?" When the land public heard the words that were still full of emotion just now, he looked at it and immediately asked curiously.

"......" was forced to curl up on the small bed, and the naked man looked at the black medicine powder that had been applied to the shocking wound on his stomach, and shielded the burning pain with strong willpower, and studied it carefully, and found that there seemed to be some lumps in the powder, but he didn't notice it before because of the dim light.

After being silent for a long time, he finally thought of a possibility, and couldn't help but ask, "How long ago did Your Excellency get this hemostatic dispersion?" ”

"Well, if you think about it, it seems like it was more than a hundred years ago......"

Halfway through his speech, he probably finally realized something, and his voice began to become quieter and quieter, and as his words stopped, the small residence fell into a dead silence.

The eyes of the land lord and the injured man focused on the location of the wound at the same time, looking at the black clumpy medicinal powder covering the hideous wound, and for a moment it seemed that there was white smoke rising from the burning, and the muscles spasmed uncontrollably because of the severe pain......

It's poison, right? It must be, hemostatic powder can indeed stop bleeding, but poison also sees blood to seal the throat!

"Ah, this medicine has expired! The immortals forgive their sins, and I will take these medicinal powders off! ”

"Stop, wait! Don't use your hands, use spells, spells! ”

"The little god doesn't know this spell, the little god is just a land ......."

"It's been more than a hundred years, is it true that Your Excellency has been slacking off and has not studied seriously at all?"

"It's already a land lord, what else is there to study seriously, how can someone who doesn't know each other in these years be promoted, anyway, if you don't do bad things, you won't be resigned, what's wrong with putting a rotten salted fish? Don't worry, my hands were the most flexible and ingenious back then, and I was the first when I made baskets! Of course, the immortals can also come by themselves......"

"If I could come by myself, I would have dealt with it myself a long time ago, and now isn't the spiritual power depleted dantian damaged and recovering? Wait, why don't you get me some wine? I think I'm still saved! ”

"Ahem! Stop, two, especially you, the land lord, if you go on like this, if you really kill a monk, maybe your iron job bowl will be lost......"

Watching the play and seeing the current Du Kang, he finally couldn't help but jump out to stop the situation from going further.

Obviously, one is an immortal, and the other is a monk with cultivation, even if he encounters something like being seriously injured, shouldn't he be very easy to deal with it calmly, right?

One came out to experience without healing pills, and the other could keep the medicine given by mortals for more than a hundred years before giving it to others...... It's like deliberate murder.

If it weren't for Du Kang's ability to vaguely sense that this land lord was indeed not intentional, maybe he would really have to suspect it in that direction.

As soon as Du Kang said this, he startled this monk and immortal at the same time, and looked at Du Kang's side, his eyes were full of surprise, and he asked in unison, "Who are you?" ”

They didn't even notice the slightest movement of Du Kang's arrival!

"Du Kang, Mu Tu Du, Guang Li Kang."

"Bacchus Du Kang?!" ×2

Coming, coming, that familiar feeling came back.

Du Kang felt that he was about to get used to it, and he was even a little too lazy to explain. You can't blame them, who made the name of the god of wine a very loud group among the gods? If it is really as Shi Yuye said, three bowls of wine drunk heaven and earth, then the personality of the god of wine is estimated to be completely different from the almost invisible situation in myths and legends......

As for how it is, we can only see it later.

"It's just the same name and surname." Du Kang waved his hand, thought about it and explained, others misunderstand others, and he can't impersonate, these are two different things, and they are also different natures.

As soon as Du Kang's mind moved, the residence of the land lord began to expand automatically, and the lights became brighter, and then he glanced at the land lord, "Temporarily renovate, if you are not satisfied, I will restore it to its original state when I leave." ”

At the same time, the black clumpy powder of the poison that had been covered in the hideous wound, and it was difficult to tell whether it was a hemostatic dispersion or a bloody throat seal, also floated under Du Kang's control, and re-entered the porcelain bottle. For Du Kang, this is indeed a matter of thought, but the degree of fineness and stability of the control of spiritual power in it is absolutely beyond the reach of ordinary people.

It's like the chief surgeon can hold a sharp scalpel and cut precisely, standing still in place, while ordinary people can't hold a needle and a pen steadily, and can't control their writing. Sometimes the gap is not reflected in the big aspects, but in these things that seem small, but actually require a lot of effort and experience to do.

So it's normal that the land lord can't do this, he doesn't have the ability. Spiritual power is naturally there, but control has not been practiced. As he said, they are already the bottom of the land, and it doesn't matter, they can't climb up, and it's normal to be rotten.

As the powder was taken away, the hideous wound was completely exposed, and the internal organs could almost be seen at a glance, and there was a layer of black on it...... It's the rest of the powders that have been fused into the flesh and blood.

Du Kang looked at the monk who grinned in pain but couldn't hold back from crying out in pain, and asked, "It may be a little painful next, do you need anesthesia?" After anesthesia, there is no pain. ”

"Yes, yes!" The monk was overjoyed and agreed.

"Hmm." Du Kang nodded, and in the next second, the monk fainted as if he had been hit hard.

No, to be precise, it should have been a heavy blow, but it was just invisible malice, because you could even see some bruises on the monk's forehead after he fainted.

"Physical anesthesia is also anesthesia!" Du Kang behaved very calmly, theoretically speaking, he mastered a variety of anesthesia methods, but this kind of most trouble-free, rough man, there will be no sequelae when he faints, and it is naturally the fastest and most effective to use. It's definitely different if you change to a beautiful girl...... But if you don't encounter it, you won't be treated differently!

The land lord didn't dare to squeak on the side, not to mention that this has the same name and surname as Bacchus, just because of the ease of these operations, he knew that he was not an opponent at all.

Du Kang is still continuing to operate, the monk still has to be saved, he has a hunch, this monk is likely to be the client of the "construction worker who has mastered AI programming technology" this time, if the client is gone, wouldn't it be in vain?

So the light in Du Kang's eyes flashed, it was the Spiritual Eye Technique, Inner Vision Flesh and Blood Tissue MOD, and then he simply turned his spiritual power into a sharp scalpel and began to cut it precisely.

While doing this, Du Kang did not forget the land lord on the side, and asked, "What's the matter with this monk?" How did you get hurt and why is it here for you? ”

"Huh? Forehead...... Shangxian, don't you know? The land lord was stunned.

"I've been living in seclusion for a long time, and I just came out of the mountain, but I happened to be passing by, and I don't know much about what is going on outside." Du Kang casually pulled out a reasonable-sounding source, "Besides, just call me a son." ”

Immortals, it is normal to stay in the Cave Heaven Blessed Land for a long time and be out of touch with the outside world.

"Oh, back to the ...... If you go back to Gongzi, here's how it happened......"

PS: We never know which one will come first, tomorrow or the accident, just like I don't know that my sister will suddenly call me today and ask me about math problems...... High trigonometric functions, and differential product formulas, what are the formula for double angles and triple angles...... It's going crazy!

Ulla!
