In March, Tuyuhun invaded Lanzhou and was repulsed by the defenders.

And the Tang Dynasty did not make a big fuss about this matter, because there are still many big things to be done in the country.

But how can Li Er be the kind of master who is bullied to the head and swallows his anger!

He's waiting, waiting for weapons from military bases!

In order to build the road and have enough cement, the imperial court publicly auctioned off the cement formula, which is also a learning from Ding Yi!

As for the inventor of cement, he did not speak out about it, and also helped the imperial court to solicit merchants to buy it!

If the cement formula goes to the people, it will definitely be taken away by neighboring or enemy countries.

At first, the officials of the DPRK and the Central Committee objected, but after Li Er came to a drill, they all shut up, and no one dared to go out before Datang showed his fangs!

That one, in Jin Wuwei's camp, all the officials of Chang'an who were four grades and above gathered together.

The camp was guarded by the forbidden army, and no one was allowed to approach it!

The soldiers brought one box after another, like one box for porcelain, and protected the contents well!

Li Junxian gave an order, and one by one the soldiers with bombs in their hands threw the bombs that had been ignited ten zhang away.

Then came the sound of a devastation!

The hundred officials were stunned, what is this?

There are even some people who think of an incident a year ago, although they have not seen it with their own eyes, but this posture is extremely similar to the scene they heard!

Then Li Er explained to them the role of the bomb and how to use it!

After experimenting with bombs to blow up a wall made of concrete, the officials were silent!

Then, Cheng Biting Jin and other generals went crazy!

One by one, they begged Li Er to equip this kind of thing into the army they were in charge of, but ......

Li Er did not agree, mainly because the bomb was too dangerous and could not be used well by untrained soldiers.

sent away the convincing civil officials, leaving behind a group of military generals.

Li Er also came up with his own ideas!

Of the twelve guards, twelve thousand men were selected to form a penalty camp.

The supreme commander of this punishment camp is Li Er, and as for the deputy commander, Li Er has set up an assessment, and only through the examination can he be competent.

Punishment camp, this name is Li Erqi, this name means to punish rebels and enemies on behalf of him, the emperor, he is old!

The generals were taken to the military base by Li Er in the second, and since it was built, only Ding Yi has been here.

No one from the other officials has been able to come in yet, because it is guarded by the Xuanjia Army, the pro-army of Baiqi Si and Li Er.

Military bases are now more than just bombs!

Zhuge repeaters, flintlock pistols, red-coated cannons, etc., are all in their research categories.

Zhuge repeaters have been able to be mass-produced, but the production is somewhat low, with only a hundred of them each.

This time, he brought the generals over, and Li Er was also preparing to equip the guards with this Zhuge crossbow.

Bows and arrows can be thrown, but repeaters can only be fired horizontally. There are pros and cons to both sides!

Therefore, Li Er is going to equip each guard with 1,000 to 5,000 crossbowmen, which is a big killer on the battlefield! But it is also limited to field battles, and siege crossbowmen will be a little weak.

The generals were overjoyed one by one, this was an artifact for them!

Of course, this repeater will be distributed to all the cavalry, in addition to the soldiers who are assigned to each guard!

Only when the cavalry is equipped with this repeater can the power be maximized!

After watching the repeater, Li Er took the generals to see the flintlock pistol again!

Today, it is rare for him to be a tour guide, and it is completely voluntary, and there is even a faint pride in his heart!

The flintlock pistol can now only shoot at 40 zhang, and the effective killing range is within 20 zhang.

If it exceeds 20 zhang, the accuracy is much worse!

Bringing the generals to see this, Li Er was to see if the generals could make some good suggestions.

Although he believed in Ding Yi in his heart, there were some things he still wanted to rely on himself or his subordinates to learn completely from Ding Yi, and he was a little unhappy in his heart!

Seeing the flintlock pistol, the generals once again fell into madness!

There is such a thing, archers or a problem? The training of archers in the Tang Dynasty not only requires physical strength, but also costs a lot of resources, because ordinary people can't pull the four-stone bow. And the four-stone bow is the standard for archers!

With this flintlock pistol, this is much less demanding than an archer!

As long as you can hold a gun, after a period of training, it is a complete killer!

And it can be formed very quickly, unlike archers, who need years of training!

Seeing such a scene, the generals were bloodshot one by one, and looking at each other was a kind of hatred and hatred!

You can't let someone else snatch it!

However, Li Er's surprise to them was not limited to that!

The generals wanted to beg the emperor to allocate these equipment to their guards, but the emperor took them to the next place without hurry!

With this experience, the generals are even more looking forward to what will come next!

When they saw a one-and-a-half-caliber steel pipe, they were stunned, what is this? Let the soldiers carry it?

And this thing, if you look upside down, how does it look like something unique to men!!

But when Li Er ordered the Xuanjia Army to experiment, they almost sat on the ground in fright!

With a bang, a deep pit was blown out of a hundred zhang away!

This......

If this thing is blown up in the army, it will be ......

Seeing the performance of the generals, Li Er said that he was very satisfied, and he held it for almost a year, just to see people's unbelievable expressions!

Next, he wants to see the frightened expressions of those people in the enemy country, and when Datang is invincible!

The red-clothed cannon was given to Li Er by Ding Yi when he returned to Xincheng last year, in order to calm Li Er's mood and ease the relationship between the two!

Moreover, Ding Yi also took out the drawings of armored vehicles and tanjiao, which he drew by himself, and understood the purpose, and showed that Datang was not capable of making these things.

After Li Er saw it, he also believed it! To be able to build a cannon, Ding Yi had already transferred a group of people from the machinery factory and research institute to the military base for research.

If it's that tank, Datang really doesn't have the ability to build it!

The redcoat cannon now has a range of only about 100 zhang, and this is only the 1.0 version. There is also 2.0 that is being improved, but it will take time!

After seeing the red-clothed cannon, Li Er took the generals to see the Air Force again!

Yes, it's the Air Force!

Trained a team of Xuanjia troops, controlled the hot air balloon equipped with bombs, incendiary bombs, and repeaters, and conducted a wave of demonstrations!

This completely shocked the generals, what they saw today was completely beyond their cognition!

It's been decades of life, and it's the first time I've seen something like this!

If there was such a thing more than ten years earlier, who would Datang still be afraid of?

After returning to Chang'an, the generals closed their doors one by one, and they didn't tell anyone what they saw!

They understood what Li Er meant by showing them these things, and no one would reveal them!

Next, it's to see if we can win the deputy commander of the punishment camp!

And they're guessing, or sure!

These things must have been made by Ding Yi!

The military base was built by Ding Yi and Li Er, and all officials know this!

And the things inside, except for Ding Yi, they couldn't think of anyone else!

The rise of Datang is in sight, no...... Invincible in sight!
