Crown Prince of the Empire, I quit!

Soon, Qin Ming arrived at their warehouse.

There is still some unused gunpowder piled here.

Of course, Qin Ming did not check these things carefully.

The other party's craftsmanship level does not meet Qin Ming's standards at all.

After waving to the people beside him, Qin Ming ordered:

"Send all these materials back to the rear, and have them disassemble them and take a look. If there are any that can be used, we will directly use our own processing plants to make them."

The opponent's weapons and equipment can all be redone.

This also saved Qin Ming a lot of effort.

"Yes!"

soon.

Qin Ming came to their anti-aircraft gun, where there were several gun barrels as long as arms placed alone.

The gun barrel was divided into several sections. After Qin Ming drew out his sword, he knocked along the gap in the middle.

With just a casual knock, the shell broke into two pieces.

"What's it connected with? Glue?"

Wu Qingye had already followed and was surprised when he saw this situation.

Qin Ming also used his sword to knock on several other joints again.

Soon, the anti-aircraft shell was broken into pieces by Qin Ming.

“It’s really connected with glue!”

Wu Qingye was too tired to complain at this time.

Qin Ming did not look down on these people.

After all, these weapons are enough to pose a threat to their hot air balloons.

“It’s a good idea, but their production quality is really poor.”

"Send all the remaining gun barrels back to the rear, and let the people in the workshop figure out how to make long-range artillery shells."

Qin Ming found it very interesting that the other party's method of exploding section by section to generate thrust and allow the shells to be sent to farther places.

After being plagiarized for so long, Qin Ming also wanted to learn some new things from the other party.

However, Qin Ming learned their anti-aircraft guns not to deal with aerial threats.

But it is to allow their artillery to fire at a longer distance.

According to the other party's method, Qin Ming can make some artillery, but the accuracy may be affected.

The most important thing now is to let the craftsmen in the workshop find ways to improve accuracy.

"Your Majesty, I feel that if we make it like this, the accuracy will definitely not meet your requirements."

Wu Qingye spoke hesitantly, and what he said did make sense.

Qin Ming looked at it with a smile, and then asked:

"Do you remember how they attacked our hot air balloon?"

"Firepower...coverage!"

"Are you going to follow their example?"

Wu Qingye quickly realized what Qin Ming was going to do.

It is indeed difficult for them to achieve extreme precision now.

But if they fired a large amount of artillery fire at a long distance, they could cover a more distant area of ​​the battlefield.

It is equivalent to having the ability to kill, which is enough!

"Yes, in terms of gunpowder inventory, we far exceed the Northern Dynasty."

Qin Ming and his friends have been playing with firearms for many years.

However, it was only in the last two years that the Northern Dynasty finally learned its lessons from the war.

And began to manufacture firearms on a large scale. Their inventory was much smaller than Qin Ming's.

In addition, their factories and earning power were not as good as Qin Ming's, so the ammunition they produced was naturally very little.

This will take a long time to make up for, and the current Northern Dynasty clearly does not have the spare capacity.

"I understand!"

Wu Qingye suddenly understood.

Qin Ming patted him on the shoulder.

"Don't continue fighting in the next few days. Once we've taken all the civilians here, we'll open Tianhe Pass."

"You don't want to take on this hot potato."

Wu Qingye was not surprised. Tianhe Pass was occupied by them just to accommodate the people from the Northern Dynasty.

But Qin Ming never thought about taking over this place.

The reason is very simple. This is also a vast plain and there are not many favorable places.

Might as well give up here.

They withdrew their defense line back to the rear where trenches had already been dug and mines laid.

That is Qin Ming’s main battlefield.

"There's no time left to rebuild Tianhe Pass. We might as well give it to the Northern Dynasty. Once they get this hot potato, it will become a weak point in our attack."

"Before leaving, completely destroy this checkpoint."

Qin Ming spoke calmly and analyzed the current situation with him.

After throwing this hot potato back to the Northern Dynasty, they will gain the advantage, which is a way of retreating to advance.

"Your Majesty still has a solution!"

Wu Qingye immediately smiled happily and led his troops forward.

Qin Ming returned to the rear, ready to provide them with more support supplies and manpower.

However, as soon as he returned to Los Angeles, Chen Shimao found him.

"Your Majesty, it seems the internal combustion engine has undergone several rounds of improvements. The pulling force it can generate must be even greater than that of the existing steam engine."

Qin Ming raised his eyebrows when he heard this.

"Take me to see it."

Soon the two arrived inside the arsenal.

Several of Qin Ming's most senior craftsmen gathered here.

The internal combustion engine is one of their greatest secrets.

Qin Ming could easily let Bei Chao steal technologies such as firearms.

But the internal combustion engine and steam engine can completely change the era.

Qin Ming must protect it well in a short period of time.

This is why we value these technologies.

Qin Ming set the highest level of confidentiality.

Only some of the most senior craftsmen he is most familiar with have the right to participate in and conduct research.

"Your Majesty, this is the internal combustion engine we made."

Several craftsmen quickly brought Qin Ming to a mechanism.

Compared to a steam engine, the size of this internal combustion engine is very small.

Qin Ming whispered:

"Can you move a large piece of iron and make a tank?"

As soon as these words were spoken, everyone present looked embarrassed.

"It seems not. Although the power of internal combustion engines is much greater than that of steam engines, the power they can generate is still somewhat limited."

"If we're going to make some small tanks, it should be OK, but we still need to do some further research."

Several people explained the current situation to Qin Ming, and Qin Ming's mind was very flexible.

When Qin Ming heard them mention small tanks, he thought of cars.

However, with the technology of this era, it is basically impossible to make a modern car.

But they could use internal combustion engines to drive some iron four-wheeled vehicles, shuttle across the battlefield, and crush countless enemy troops.

"What do you think of making some chariots the size of horse carriages, adding steel spikes to them, and reserving holes for cannons and firearms, so that they can become small mobile fortresses on the battlefield?"

Since Qin Ming can't make a tank, he can only seek some new changes.

A small fortress like this, with a thick layer of iron sheet on the outside and three or four people inside, should be able to accommodate it.

However, with the current technology, the people inside will probably suffer a lot.

Still need to add some shock absorption devices.

By the way, they used the rubber they had collected from the Nanman to make tires to reduce the bumps on the soldiers inside.
