Leaving the Wang family in a hurry, Li Zexuan went straight to Jingzhao Mansion without even returning home.

After revealing his identity to the yamen servant in front of the door, Li Zexuan was invited to a side hall of the back yamen. About a quarter of an hour later, Yin Huawenjie of the Huafu came in wearing a purple official uniform. He cupped his hands at Li Zexuan and said with a smile:

"Hey~! Mr. Li, I wonder if you are here today. What can I learn from you~?"

Things are different now. Li Zexuan is now the third-rank prince Zhan Shi, a rising star in the empire. He is no longer the little "teacher" of the Imperial Academy. Hua Wenjie has to be polite when he sees him.

"Haha~! I have met Hua Fu Yin. I have something to ask Hua Fu Yin for help today~!"

Li Zexuan didn't make excuses, he politely returned the gift to Hua Wenjie and said with a smile.

Hua Wenjie's eyes flashed, and almost in an instant, he thought that what Li Zexuan was going to say should be related to the assassination case, because he and Li Zexuan had no contact with each other on weekdays. If they had any intersection, it was only the assassination case a few days ago.

Case closed!

Thinking of this, Hua Wenjie's expression perked up, he quickly waved his hand and stepped away, sitting next to Li Zexuan, and said: "Li Zexuan has something to do, but it doesn't matter. As long as I can do my best, I will definitely help him~!"

Li Zexuan nodded and said: "I think Hua Fu Yin can also guess a thing or two. Yes, I came here today precisely for the assassin. I have found out the origin of the assassin, but I need Hua Fu Yin to help me find out."

That assassin’s hiding place~!”

"Oh~! Li Zhanshi, tell me~! Where did the assassin come from~?"

Hua Wenjie's face flashed with excitement and he said quickly.

In fact, he felt bitter!

Seeing that the ten-day deadline given to him by Li Er was about to come, the detectives from Jingzhao Mansion failed to find any useful clues. On the contrary, many ruffians in Chang'an City had been arrested in the past few days.

It cannot be said that the government officials in Jingzhao Mansion were not doing well. It was actually because Li Zexuan provided too few clues. They knew nothing about the black-clothed assassin's appearance, age, origin, etc. So where could the government officials arrest him?

This era is not like modern times. There are surveillance cameras in key places. When encountering a murder case, you can find clues about the murderer by calling the surveillance cameras at various intersections. Investigations in this era all rely on the clues left by the murderer to gradually investigate.

.

The terrible thing is that there is very little useful information that Li Zexuan can provide to Jingzhao Mansion, so where do the officials start to investigate~?

Now that Li Zexuan can provide the identity of the assassin, why shouldn't Hua Wenjie be excited? At least he can keep his official title~!

"I have found out that the assassin comes from a small sect deep in the Qinling Mountains called Qixiu Sect. The place where that sect is located is called Snake Spirit Mountain. Today I am here to ask Huafu Yin to send someone to help me find out about this snake.

Once you find out where Lingshan is in the Qinling Mountains, just tell me! I'll deal with them~!"

Li Zexuan looked at Hua Wenjie and said seriously.

"Seven Xiu Sect~? Snake Spirit Mountain~?"

Hua Wenjie murmured a few words, then nodded and said: "Okay! I will arrange for someone to go and investigate! If there is any news, I will inform James Li immediately!"

"Thank you!"

Li Zexuan cupped his hands and thanked him.

The Qinling Mountains cross central China, starting from southern Gansu in the west, passing through southern Shaanxi and ending in western Henan. The main body is located at the junction of southern Shaanxi Province and northern Sichuan Province. It runs east-west and is about 1,500 kilometers long. It contains hundreds of large and small peaks. If no one helps

, Li Zexuan goes looking for it alone, who knows if he will find the Year of the Monkey, the Horse and the Moon?

………………………………

The next day.

Above the cloud mountains.

The morning glow reflects the morning glow, making the entire mountain peak covered in golden coat, looking extremely beautiful!

Craftsmen who got up early to work were running around, digging foundations, building walls, quarrying rocks, felling trees, and sawing wood. The division of labor was clear, and it was a lively scene.

At three o'clock in the morning, a convoy of four or five oxcarts came along the mountain road to the mountain. Some sharp-eyed craftsmen speculated whether the employer had sent good things to the workers again.

"Eh~? Uncle Fu, why are you here~?"

The shed where Yan Shaoning stayed during the day was very close to the mountain gate. He looked up and saw Uncle Fu in front of the team, so he quickly stopped what he was doing and went out to greet him.

"Haha~! Master Yan, I am bringing you new materials today~!"

Uncle Fu directed everyone to unload the bags of cement and said to Yan Shaoning with a smile.

"New materials? Is this all? What are they used for?"

Yan Shaoning did not know about the secret development of cement in the workshop during this period. He was busy dealing with the division of labor arrangements on the construction site during this period!

"Haha~! This is the cement made by the workshop according to the Lord's wishes. It is used to replace cement mortar and build walls! This thing can not only be used to build walls, but can also be used to build roads. Lord

I said that the college’s future roads will be paved with this cement mixed with sand and gravel!”

Uncle Fu stroked his beard and said with a sense of accomplishment.

"Cement~? Why is this name so weird~? Is this thing really that useful?"

Yan Shaoning opened a bag of cement, looked at the gray powder inside, and asked doubtfully.

Uncle Fu nodded and said: "Of course! The craftsmen in this cement workshop have all done experiments, and there is no problem at all! Shaoning, you can let someone try it now. The young master said that in the future, all construction of the academy must use

cement!"

"Okay, let me give it a try! Uncle Fu, how do you use this thing?"

After hearing Uncle Fu's confident answer, Yan Shaoning nodded in agreement.

"Haha, this is simple, let me tell you the ratio of adding water!"

………………………………

"Okay? That's it? But it doesn't look strong at all? If you push hard with your hand, this wall will probably fall down!"

Under Fu Bo's guidance, the workers prepared some cement slurry and built two walls with the cement slurry. However, Yan Shaoning always felt that this thing was not very reliable, so he asked Fu Bo.

"We have to wait for the cement to solidify! Even if you use glutinous rice mortar, isn't the newly built wall very fragile? Shaoning, please don't worry about these two walls today. You can look at them tomorrow. Then you can

You will find out how amazing this cement is!"

Generally, when cement mortar is at 20 degrees, it will reach final setting after five to eight hours. At this time, it can no longer be pressed with fingers. Fu Bo was very confident about this, so he said to Yan Shaoning with great certainty.

"Okay! Let's see tomorrow. If the effect is really good, then we won't buy glutinous rice mortar in the future!"

Yan Shaoning thought for a moment and nodded in agreement.

In his opinion, Li Zexuan's vision and decision-making are still very trustworthy.
