Chapter 769 (1/2)

Facing the eyes of old man Zhang, ye Jiujiu looked calm and did not adapt at all.

On the contrary, Zhang Dong and ye Xuan looked at each other, and their faces became more suspicious.

What's the matter with Mr. Zhang?

Ye Xuan looked at Zhang Dong with a taste of inquiry in his eyes, and Zhang Dong looked at Ye Xuan in the same way.

Both of them are hoodwinked.

How good is it? Old man Zhang just made a surprise attack and was caught and tied up. Now he is still so serious and looks at Ye Jiujiu with a taste of appreciation?

Is there something wrong with this drawing?

Zhang Dong thought of this for the first time and winked at Ye Xuan. After ye Xuan noticed it, he gently shook his head.

Ye Xuan has seen these design drawings, but he has not seen any difference on these drawings.

After all, ye Xuan is a layman. He is not very familiar with the design, so he doesn't notice much.

Old man Zhang suddenly said, ”since you said that these drawings are printed in your mind, let me ask you how many kinds of materials you use for underground works and what kind of building structure you have.”

Ye Xuan and Zhang Dong looked at each other when old man Zhang asked. Although Ye Xuan read the architectural drawings, he didn't understand it. As for Zhang Dong, not to mention that the goods are iron and simple. It's OK to ask him to pay for it. It's obvious that he is embarrassing him.

For a moment, ye Xuan's eyes fell on Ye Jiujiu.

Ye Jiujiu said calmly: ”there are 325 kinds of materials, and the proportion of each different material is also different. In addition, some basic mortise and tenon structures need to be used. Although no nail is added, it can support the whole mountain without being detected by any exploration instrument...”

Everything seems to have been printed in Ye Jiujiu's head. Ye Jiujiu knows all kinds of structural materials backwards.

Ye Xuan breathed a sigh of relief. Although he knew that ye Jiujiu was very capable, if there were some mistakes at this time, the old man would be angry.

But now it seems that the effect is very good. Just looking at the shocked look on old man Zhang's face, we can roughly infer the old man's thoughts.

Zhang Dong's face was full of joy. Ye Jiujiu's brilliance proved that they didn't see the wrong person. Even if the old man was dissatisfied with Ye Jiujiu's victory, he had nowhere to get angry.

Mr. Zhang kept comparing with him, and then asked, but ye Jiu was still answering like a stream.

Old man Zhang was a little reluctant. He pointed to the two people on one side and said, ”they are your assistants. They should also be very familiar with these things, right?”

Ye Jiujiu nodded calmly. Old man Zhang pointed to a man and asked, ”tell me how to do surface engineering.”

”A total of...”

Once again, old man Zhang was shocked.

This is the engineer Ye Xuan found. No wonder they dare to dump all kinds of things to Ye Jiujiu!

Such superhuman business ability is absolutely rare in the world!
