Super Cultivation System of the Three Kingdoms

Chapter 646: Long-awaited Exchange
The next day, Liu He got up early, washed up quickly, and went to the study. Sure enough, Xun Yu and the other two had not arrived yet.

"Come on, System Boss, come out for a moment, I have something urgent to deal with."

"If the host has any instructions, just go to the corresponding interface and don't call this system."

"Uh... your personality is still so cold." Liu He complained, but ever since his power grew, he has rarely dealt with the system. Apart from some daily prompts like triggering special skills from the system, there are almost no interactions, so much so that he almost forgot that he is a time traveler with a golden finger.

He quickly opened the "Item Exchange" interface of the system in his mind, and then scrolled down until he reached the item list of the fourth-level system.

Liu He hadn't looked at this list of items for such a long time that he had almost forgotten it.

Level 4 system exchange items:

1. Ordnance:
Battleship manufacturing map: 800 points.

Large military equipment atlas: 600 points.

2. Materials:
Kitchen Records: 500 points.

Total mineral record: 1000 points.

Rejuvenation Divine Record: 1200 points.

Records of Divine Crafts: 1000 points.

City-building Codex: 800 points.

Water Conservancy Sutra: 1000 points.

Pest and disease control secrets: 600 points.

3. Special Items:
Global Nautical Charts: 1500 points.

Upgrade the Meditation Tower to the Spirit Tower: 1000 points.

Among these items, he had already exchanged the "Large Military Equipment Atlas", "Mineral General Record", "Water Control Classics", and "Pest Control Secret Records" and handed them over to three smelting masters, Qian Li, Tong Jian, and Zhan Lian. The well-locked chariot and fire beast that suddenly appeared outside Huguan that day were made according to the atlas. Their power was so strong that it was shocking. This was just the tip of the iceberg in the atlas. As for the other three books, they were also very effective.

In view of this, Liu He is naturally full of confidence and looks forward to the items in this four-level system.

"Come on, come on, exchange the "Record of Divine Works and Objects" for it."

"Ding... The host has consumed 1000 points and successfully exchanged for items."

On the table in front of him, a bright light flashed, and a very thick and exquisite book appeared. Liu He stretched out his hand to weigh it, and it was probably about five or six kilograms.

I flipped through a few pages and found that the content was indeed very complete, with rich pictures and texts, and very detailed explanations. It is simply an encyclopedia of ancient handicrafts.

"Haha, with this thing, are you afraid you won't make money?"

Liu He held the book in his hands, as if he had found a treasure, and smiled from ear to ear.

"Well, this is a great treasure. It would be a waste to give it directly to the company. Let me think about which of the relatives would be the most suitable to give it to..."

Liu He calculated rapidly in his mind.

"The Zhang and Su families have the second and third brothers as their pillars, and each has a son serving as an official in the local area. Both of them have become county magistrates. After I ascend the throne, it is only natural to confer titles on meritorious officials and make them prefects. They should not need any support for a while. But the Zhen family..." His eldest son Liu Zheng had an arranged marriage with Zhen Mi of the Zhen family. Although Zhen Mi had an elder brother, she was only thirteen years old and had no way of becoming an official. Her father Zhen Yi, although he inherited the position of Shangcai Ling, was mostly an honorary title. The family was still mainly engaged in business and did not have much influence. After he took control of the government, he did not give them any special treatment. The current Class A VIP merchants in their company were all accumulated by themselves.

"Well, this is my own in-law, so I should take care of him. The Zhen family runs a wide range of businesses, so they are the most suitable for this. It's settled. I will send someone to Zhongshan to bring Zhen Yi to Luoyang to discuss this big business with him."

Liu He looked at the book in front of him as if he was looking at a mountain of gold, with a smile on his face and he was overjoyed.

He was about to close the system page when his eyes suddenly caught sight of something.

"Huh? This is..."

He saw the book "The Holy Book of City Building" and immediately became interested.

"Looking at the name, it's obviously a book about building cities. Haha, I haven't used the system for so long that I've forgotten what's inside. If I had exchanged this treasure earlier, Yunhai County might not be in trouble now. I'm so stupid."

Without saying a word, he spent another 800 points to exchange for the "City Building Holy Book".

After a flash of light, another huge book appeared before his eyes.

He directly opened the catalog and began to search carefully, reading word by word. His eyes moved closer and closer to the book, as if he wanted to bury his entire head in the book.

"Ha, I found it, it really is there!"

He pointed his finger at the place where he pointed, and there were a few words written on the catalog: "All kinds of building materials - cement."

Liu He couldn't wait to turn to the corresponding page, and lines of text and pictures came into view.

He read it carefully. Although he could not understand all the contents, he could still understand about 50% by comparing it with the pictures.

After reading it, he was a little disappointed.

"It turns out to be just a simplified version of cement and concrete, not at all the kind I saw in my previous life."

However, this disappointment was only a small part. Excitement and excitement still occupied most of Liu He's emotions.

This simplified version of cement and concrete was made based on what was feasible at that time, using some other materials to replace the chemical materials of later generations. Although there would certainly be obvious differences in hardness and other aspects, according to the description in the book, it could fully achieve the effect that He Chang imagined of "automatic filling, quick drying and quick hardening".

The most important thing is that this simple cement and concrete is easy to make and has low cost. Once it can be mass-produced, it will not only greatly save the cost of building the city of Yunhai County and smoothly control the construction period, but also allow him to make a fortune.

"I'm rich, I'm rich, haha, what a mistake, why didn't I think of asking the system for help earlier, stupid, really stupid, haha!"

Liu He smiled and put both books in his arms.

"I will send someone to deliver this book to Yunhai County. After the Yunhai County project is completed, I will reward the merchants and craftsmen who have made contributions according to my previous promise. Then I will recruit these craftsmen and form a team of craftsmen belonging to me. Then, according to the methods in the book, I will help the country when the court needs me. In my spare time, I can build roads, houses for others, or even tombs. Are you afraid that I can't make money?"

If this could be implemented, it would be equivalent to owning the first regular, professional large-scale engineering team of this era. Not only could he make huge profits, but he could also make the roads within his sphere of influence wider and the cities stronger than others. Wow, Liu He almost laughed out loud at the thought.

"Well, this thing is so precious, I am not sure if I can give it to an ordinary person to deliver. It would be best if I ask someone to copy a copy first, and then give the copy to the Flying Eagle Guards to make the trip."

Both major problems were solved. Liu He was extremely happy and ran and jumped back to Zhang Yu's courtyard.

A few days later, the Zhen family's carriage stopped at the gate of the general's mansion. After a long time, the servants in the mansion heard several loud laughs coming from the study, which scared the servants and maids in the mansion.
