Although Liu Bang popularized the ring-handled knife in the army, the cavalry was equipped with stirrups, and created a heavy cavalry army of 500 people, it is said that the Han army equipped in this way is unrivaled in the whole world. Pen @ fun @ pavilion wWw. ｂｉｑUｇE。 ｉｎｆｏ

If it weren't for the geographical limitations, the expedition to the world would not be a dream at all.

But I always feel that Xichu will not be so weak - after all, in the Xichu camp, there is still a traverser Yu Ji, will she also be like Liu Bang, competing for the general trend of the world, while silently developing military merits in the rear?

Liu Bang can build a cavalry army, invent ring-handled knives and stirrups, can't Yu Ji do it?

Maybe even more perverted ones were invented, such as Mo Dao?

Immediately, I felt that I had thought too much, with the industrial level of the late Qin and early Han dynasties, it was impossible to create a big killing weapon like the Mo Dao - the only possibility, Yu Ji came with a whole set of theories and related industrial technologies.

But it also takes time.

The outbreak of science and technology is definitely not a matter of one or two years, the collection of resources, the training of personnel, and the design of technological processes are by no means as simple as talking.

What's more, there is still that female madman in the Xichu camp.

A traverser with a pure sky, this madwoman also wields a hot weapon that can cause the Great Wall to collapse with a wave of her hand.

If this thing is brought to the battlefield, it will be a god......

Not long after worrying about the affairs of Xichu, Li Fuyao found a situation with pain: Liu Bang wanted to make progress too much, and he still had to do something......

One day, after training the heavy cavalry, Li Fuyao followed Liu Bang back to his study in the Xianyang Palace, and happened to see Xiao He holding a roll of coarse paper to ask Liu Bang for advice.

In the Western Han Dynasty, there was already the appearance of coarse paper.

Li Fuyao glanced at it inadvertently, and his heart suddenly jumped wildly.

Suddenly it's a strange knife!

Comrade Liu Bang really tried to build a Modao in the Western Han Dynasty?

This Nima is going against the sky.

Later, Li Fuyao and Xiao He went out of Xianyang Palace together, and they talked about it, Xiao He didn't want him, but said something, saying that our Han Wang classmates had gathered all the craftsmen in the territory, and increased the development of minerals, and gave a complete set of refining methods, planning to design according to the drawings to create a more advanced war weapon than the ring-handled knife.

Li Fuyao could only be speechless.

What did Liu Bang do before he crossed over?

It is estimated that it is engaged in industry.

Otherwise, it would be difficult for ordinary people to come into contact with the industrial knowledge of ring-handled knives, stirrups and knives.

But can Liu Bang really succeed?

Li Fuyao has no bottom in his heart, maybe it will take time, but if there is a complete set of technological processes, all efforts to train craftsmen, and the whole country to build, it is really possible to succeed.

However, with Xiao He's complaints, Li Fuyao was shocked.

Liu Bang is very ambitious.

The self-motivation of this product is not at all comparable to any of the time-traveling people he has met before - as long as he is given time, this product is likely to really build a truly invincible empire.

Ring-handled knives, stirrups, and heavy armor have been born.

Mo Dao is still operating in the placenta, but the things he handed over to Xiao He are far more than Mo Dao......

The improvement of siege vehicles, the evolution of chariots, the evolution of stone-throwing vehicles to return vehicles, and even allowed Xiao He to collect a large amount of charcoal and mine a mineral called saltpeter.

Xiao He also revealed that Liu Bang's children's shoes are studying this kind of thing called sulfur.

He once said to Xiao He that the mined pyrite and charcoal will be distilled in layers, or you can get what you need.

Isn't this the pure sulfur refining method mentioned in the Eastern Han Dynasty's "Shennong's Materia Medica"?

This thing wants to make black powder?

Is it because he lost Han Xin and plans to use technology to make up for the loss of the lack of military saints?

Nima, this is too against the sky, if you toss out the Mo knife, you can still say that you are tossing out a hot weapon -- if Comrade Liu Bang really has a whole set of theories about the industrial system.

With theory, coupled with decades of research, it may be possible to come up with some prototypes of thermal weapons.

Of course, muskets are not extravagant.

No matter how good the industrial theory is, it is impossible to support the creation of muskets in the Western Han Dynasty.

But there can be rockets or something......

Well, this rocket is not the kind of rocket that can fly and do everything in the future, but a rocket with black powder tied to a feather arrow, and this thing also has a certain lethality.

Li Fuyao is not worried about Liu Bang's science and technology to rejuvenate the country.

Black flame requires not only charcoal, but also sulfur and potassium nitrate.

The latter two materials are definitely not obtained by relying on a little theoretical knowledge, and a lot of practice is required, Liu Bang is the king of a country after all, and the time spent on this is limited, so the possibility of black powder succeeding is a little slim.

But this can't stop Liu Bang's ambition to rejuvenate the country through science and technology.

Black powder and Mo knife are both long-term solutions, and this thing has done some other things, such as the invention of chairs......

This one is much simpler.

As long as there is a design pattern, find the best carpenter to create it, and then promote it nationwide.

And then...... This product used the pouring method to invent the iron pot.

For this invention, Li Fuyao was a little speechless...... Liu Bang, who is also a foodie, finally roared angrily at the diet of the late Qin and early Han dynasties, and wants to improve people's livelihood?

However, it will also take time for this iron pot to be promoted to the whole country.

There are many more such moves.

But Li Fuyao keenly discovered one point: Liu Bang's progress is limited to the range of possibility, and it is not absolutely ahead, which is countless times better than Wang Mang.

For example, things like vernier calipers, Liu Bang didn't move.

The only thing that was too much ahead of the times was the Mo knife and black powder...... But he probably didn't expect too much of these two things.

It's one thing to have a theory, it's another to have soil and an environment.

I still know how to make AK47, but it is useful, and I still know the simple principle of the atomic bomb, but there is still no use for eggs, so Liu Bang's focus is still on the development of cold weapons.

At the same time, the reform of the system began to be studied: this is a big deal.

Obviously, Liu Bang knew the story of Wang Mang, the chosen son, and was extremely cautious in system reform, and he studied with Xiao He for a long time, but they were all in the embryonic form, and no policy was introduced.

I have to praise that Liu Bang really did great things when he came to history.

But in the end, it may really be the same as Wang Mang and go astray.

Although there is no such thing as a development, the other side is not idle, Xianyang Palace has been filled with three palace maids, well, this goods have completely moved Zhou Tianzi's set, one after three ladies and nine concubines and twenty-seven wives......

Don't live too comfortably.

In this regard, although Lu Pheasant has opinions, he does not dare to say it.

After all, Liu Bang is still the master of the house, and besides, women in this era are obedient, and it is not too normal for men to have three wives and four concubines.

However, Xiang Yu, the overlord of Western Chu, will not let Liu Bang continue to be comfortable.

Soon, Xiang Yu launched an offensive against Han.

First of all, Linjiang sent troops to attack the Han army, and after fighting a tentative battle and groping for the allocation of troops, the army hoarded and prepared for the final Chu-Han decisive battle.
