On the Great Wall of the Border, there was a white girl sitting next to Zheng Yichen. From the appearance, she was a girl, but in fact she was a hundred years old. The other party was looking at a book seriously, while Zheng Yichen was looking at a design drawing in another place, with some design drawings about the Great Wall of the Border. Angelia was extremely satisfied with Zheng Yichen's attitude of cooperation.

So you can take out something very important when you take action. This thing is a top secret thing on the Border Great Wall. Those acting city lords have no chance to see this thing. Although this thing cannot thoroughly analyze the internal environment of the entire Border Great Wall, it can allow Zheng Yichen to understand some unique secrets of the Border Great Wall to the greatest extent.

Then he can use this as a basis to make some additional improvements to the Border Great Wall. Although the construction technology on the Border Great Wall was top-notch in both the past and now, the top-notch level is top-notch, and Zheng Yichen mastered ancient technology, which can make this top-notch level go further.

Snatch. "..." Putting down the design drawing in his hand, Zheng Yichen glanced at Angelia, and the other party looked at a book in his hand seriously. As soon as he stood up, the books in his hand of the super-old white girl closed with a bang, as if it was a diary that an indecent person didn't want others to see.

Zheng Yichen sat back again: "I can adjust this design. Without demolishing and rebuilding, it is expected that it can enhance the strength of about one-third of the border Great Wall."

"Is ancient knowledge so powerful?" Angelia asked in surprise. If it is demolished and rebuilt, it is already a great improvement. However, what Zheng Yichen said is not demolishing and rebuilt, but bringing such a great improvement on maintaining the original foundation.

"How much do you know about ancient knowledge?"

"Uh, very few." Angelia shook her head. Although she had lived for a long time, she had not left the Great Wall of the Border in the past few hundred years. All her knowledge about the outside world was limited to the intelligence department, and her knowledge was limited to the books she had come into contact with and the teachers she had come into contact with. It was because she was able to access the Internet recently and she had come into contact with more things.

It is said to be very rare, but in fact it is just a darkness equal to zero.

Seeing this, Zheng Yichen did not continue to talk about this topic, but just explained the direction of the adjustment of the design drawings. Angelia could understand this aspect. After all, she is a hundred-year-old girl. No matter what, she will have a long boring time to learn something and pass the time.

Since he could understand, Zheng Yichen did not need to spend any extra time explaining. After agreeing on this matter, he took a special order. As for future transformations, this cooperation is a secret, and Zheng Yichen is not losing money now. After all, Angelia made an additional promise at that time.

If Zheng Yichen has no way out, then the Great Wall on the border is the last way out. Although he would have to be a guard here at that time, it would be better than losing anything, right?

"Okay, some things about the city lord have been done, but the other party seems to have a little inexplicable affection for me. Could it be that I have become really handsome recently??" In the underground base, Zheng Yichen placed the design drawings on the workbench and waited for new adjustments to make. Before that, she looked at herself in a mirror.

I repeatedly confirmed my appearance. It seemed that after Heita's adventure, I really became much more handsome??

"Where do you think you have changed?" Anne asked dryly.

"The skin has turned white." Zheng Yichen said with certainty.

"What about something else?"

Miaoshuyuan's fanaticaosHUYUan.coM. "The rest are changes in small details, and I haven't noticed it yet." Zheng Yichen said seriously, noticed another look, and coughed lightly: "Some of what I just said is really that way. The White City Lord does have an extra favor to me. I don't know where that favor comes from."

Miaoshuyuan miaoshuyuan.com Miaoshuyuan. "Even if I fall in love at first sight, I didn't have a human form back then, right? Or is she a hidden witch? I saw that I did so many things to the witch, so I had that extra favor?"

"You go and ask her directly." Annie gave a very reliable suggestion. Zheng Yichen thought this was unreliable, so she bowed her head and started working seriously. This design drawing is not difficult to improve with ancient knowledge. It is based on the existing structure of the Great Wall of the Border Wall, and some internal optimizations are carried out.

Then some spellcasters can adjust the magic array structure on each brick one-on-one. This cannot be done from the outside, but the records on the design drawing are very clear. There is a chance to adjust this internally. Before receiving the support of ancient knowledge, it was difficult for Zheng Yichen to do this.

With the support of ancient knowledge, this is not a big deal. As for whether this little secret can threaten the Great Wall on the border? Well, depending on the situation, it is OK to operate outside, but if it is internal, he doesn't think that the white city lord at that time would be easy to speak.

Yilin and the others were very busy. Zheng Yichen was trying some other things here and gave the design drawings a week later. During this period, something that Zheng Yichen was quite helpless happened. Abyss monsters appeared on the continent. Although under the monitoring of the Sky Eye system, the abyss monsters were controlled at the first time, but not all of them were controlled.

Those abyss monsters and mystery points mixed together, resulting in new changes. Before this, the Sky Eye system also suffered some blows, at the cost of abyss disguisers and abyss lurkers on the continent were killed in large numbers, but their sacrifice was exchanged for the abyss monsters entering the continent.

According to the investigation results, the way monsters enter the continent is the teleportation array!

This situation can be said to be unpredictable. Although the teleportation array is difficult to make, it is not impossible to set it up. Even if some special materials are needed, relying on the teleportation array to remove firewood from the bottom, it is OK on the abyss.

"It's getting more and more messy." Zheng Yichen popped up the adjusted design drawing, and was speechless about what happened on the mainland.

"Why, do you want to go to the battlefield again?"

"I'm not a professional combatant, but the Abyss War did have me collected a lot of data. How are your super ancient biological illustrations researching?"

No one can be sure whether it was a god or not after ancient times, so in order to describe it safely, it is tentatively determined to be super ancient. More detailed information is to wait for those divine texts to be cracked, and then learn about the story of that era based on some documentary records on the Black Tower Sandbox.

"Generally, although the picture books are very perfect, there are too many things missing. Even if I give me a hair, I can make something, but the picture books are like this." Annie's tone was a little helpless. It was hard for a cook to cook without rice. Even if I give her a hair, Yilin could use her life magic skills and her own abilities to create some special life magic skills.
