(Thanks to Splendid Life 58, the King of the Emperor and the Queen of Earth, the crow that feeds back, yyaJy2304, ulippl001, the drunken eyes of a thousand peaks, and wants to go to the Nine Shadows to find people for the reward...... ）

It was the first time Liu Shengzhi had seen this kind of survival freak, he had only heard of such people before, but today he saw it with his own eyes. It's truly breathtaking!

The so-called survival mania is a man who worries about the sky. All day long, I was always worried that the end of the world would come.

Such a safe house is prepared for the end of the world. Not only are there countless supplies piled up inside, but there is no need to say anything about food and water.

It also has a generator, a fully enclosed air circulation system and so on......

Liu Shengzhi was amazed, this safe house alone may cost tens of millions. Even if it's a retrofit using an air-raid shelter that was already in use.

Unlike other survival freaks, Zhang Zhiyuan has always believed that after the end of the world. Humanity will be beaten back to primitive civilization.

When the time comes, you can only rely on cold weapons. Therefore, the various cold weapons prepared by this cargo can be described as extremely frenzied.

Not only all kinds of ancient war weapons, such as all kinds of trebuchets, bed crossbows and so on.

This guy even invented his own war weapons of unknown number of cold weapons, which are piled up in this bomb shelter......

Liu Shengzhi nodded again and again, in front of him was Zhang Zhiyuan's own improved bed crossbow, using a winch and a cow tendon cable as a weapon for a power catapult.

With super penetration and a range of kilometers, it definitely exceeds the power of similar weapons in ancient times.

What's even more rare is that all of them are made of wood. And without any modern parts.

In Zhang Zhiyuan's imagination, even after the end of the world, it can be quickly manufactured in large quantities and equipped!

Although Liu Shengzhi didn't know if there was an end of the world, Liu Shengzhi knew very well that what this kid had created was extremely useful to him Liu Daxian Master.

A variety of cold weapon design drawings that far exceed ancient concepts. All of them were looted by Liu Shengzhi.

See this. Zhang Zhiyuan not only did not get angry, but became more and more happy.

These various ancient weapons, designed by himself, did not work. In addition to posting it on some forums for the same enthusiasts. No one was interested in what he was doing.

Now, Liu Shengzhi, a cheap master, is interested in these things, and even makes Zhang Zhiyuan feel a little confidant.

More and more like offering treasures, he brought all kinds of things under his hands to Liu Shengzhi. It made Liu Shengzhi really buy a lot of good things.

What's even rarer. Zhang Zhiyuan's goods are definitely an industrial party.

He actually collected the scientific and technological materials of most civilizations, from burning bricks and iron, to how to invent the steam engine, using electricity, and so on.

From screening and breeding seeds and grains, to how to breed and raise horses. From information on traditional Chinese medicine, to maps around the world.

All the information that could be collected was collected. There are several large portable hard disks that are fully installed.

Liu Shengzhi naturally made a copy unceremoniously, although Liu Daxian felt that he was not an industrial party. But a lot of things. He found it very useful.

At least the level of science and technology in the time and space of the Six Dynasties is extremely low, let's just say that the steel, the output specifications are pitiful.

Liu Shengzhi has seen that most of the tools used by ordinary people to dig the ground and cut rice are either wood or stone. It's a bit of tattered pig iron, but it's still like a baby.

That is, a family like the Wang family, but they are a little richer. The vassals who cultivated their estates could also use some iron tools.

As for steel, that's just a matter of thinking. With just such a small amount of steel production, all of it is not enough for military use. Where can it be used for people's livelihood?

As for the six dynasties to build a city in time and space. But it's even worse. It can only be rammed with rammed earth, which is really troublesome.

Of course, if you can be like that Helian Bobo, you will not hesitate to work hard. It can also create a fortified city like the Tongwan City.

But most of the cities are not up to quality. Under the river, the walls of these county towns in Yunshe are in tatters, not to mention.

Even in a rich place such as San'in, the walls of the city are also grassy, and it is said that it rained heavily some time ago and collapsed for a while......

In a word. Liu Shengzhi came to find Zhang Zhiyuan, a cheap apprentice, and he came to find technical support.

Since the last time, I heard Hou Xiaochao talk about Zhang Zhiyuan. Liu Shengzhi has already been concerned.

It's just that I haven't had time to spare my hands and do these things. Now, I'm finally free.

It's a pity that the Qiankun Movement Rune can't bring people over, otherwise Liu Shengzhi really wants to bring Zhang Zhiyuan's goods over as a technical consultant.

"Yes, Master. This is a sword I built for you...... The latest ceramic material ......"

Zhang Zhiyuan is not stingy, and even this kind of person is most willing to share with others.

I thought that Liu Shengzhi had developed into a survival freak like myself, and I was a little happy. talked endlessly to Liu Shengzhi about his various ideas.

Finally, I remembered. and last time, I said that it was a sword built for Liu Shengzhi.

The heavy sword made of the latest ceramic materials is also in the shape of an eight-sided Han sword. It looks quaint and heavy, and even has a bit of bronze rust on it.

The whole sword looked as if it had no edge, and it didn't look sharp. There is no legendary sword, like a flood of autumn water, cold light and so on.

But if you really drop a hair, you will find that this sword is really a hair-blown and broken hair, and it is extremely sharp.

After taking out a finger-thick steel bar, it was effortlessly cut in half.

A drop of water was dropped, and it didn't touch the sword body, and it slipped down directly.

Such a sword, put into ancient times, is really invincible! Liu Shengzhi can't put it down.

"There are always many problems with steel, and if you take into account the sharpness, it is difficult to take into account the toughness and easy breakage. Vice versa...... And this new type of ceramics, it's different, you look at the blade.

The blade looked as if it hadn't been sharpened, and it was extremely blunt. But if you look at it under a microscope, there are tiny particles like jagged teeth......"

Liu Shengzhi understands that this is the characteristic of the legendary Damascus steel. No wonder it's so sharp!

He waved it a few times, and found that there was almost no sound of breaking the wind. It's not that Liu Shengzhi's strength has become smaller, but the shape of this sword is easier to break through the wind.

Everything seemed to be easy to handle, which made Liu Shengzhi very satisfied.

In comparison, the ceramic dagger that Liu Shengzhi carried before seemed to be just a mass product.

Coming out of Zhang Zhiyuan's safe house, Liu Shengzhi felt that he had gained a lot. sent Hou Xiaochao back by himself. (To be continued.) )
