Crown Prince of the Empire, I quit!

After the construction of the concrete wall began, the Yan army arranged a group of people to guard it day and night to prevent it from being destroyed by Daqian's troops before it dried.

To increase their tension and leave no one in doubt about the concrete formula.

Qin Ming specially arranged a group of people to take time out to pretend to attack the Yan army several times.

This made the Yan army feel like they were facing a formidable enemy.

Every time after being attacked, we would quickly strengthen our defenses and add more personnel.

Seeing how carefully they maintained the concrete wall, Qin Ming felt like laughing.

That day, he took Chang Baishan to the city wall.

The two of them held binoculars together and observed the enemy's movements.

"The Wu family is truly amazing. They built such a high wall in no time."

The telescope reflected the endless city walls that were dozens of feet high. The Wu family's sphere of influence was close to that of a medium-sized country.

The ability to mobilize resources and manpower has naturally reached the level of a medium-sized country.

"Your Majesty, what will happen to this concrete?"

Chang Baishan smacked his lips. His scalp went numb at the thought that the other party's huge investment in the future would go to waste.

From Wu Tianxing's perspective, this is definitely a loss that is too huge to be bearable.

“It will turn into powder.”

Qin Ming said lightly.

Problems with the concrete formula will make the opponent's city wall brittle and its load-bearing capacity will also be reduced.

"The offshore intelligence station has been completed, but it cost us hundreds of small boats."

"The good news is that we can now contact General Ye."

"The bad news is that after spending so many small boats floating on the sea, we are now down over 2,000 troops."

Qin Ming could still accept these costs, so he continued to ask:

"How did Ye Shoujiang perform?"

Chang Baishan told Qin Ming everything that happened over there.

Hearing this, Qin Ming calculated the time with his fingers.

“I didn’t expect that they would also reach the stage of constructing a concrete defense line.”

"This Qin Yue is really a stroke of genius. It saves us a lot of trouble."

"Haha, who says it isn't?"

"Tell them that they can start the attack in half a month, and no one will come to support them in the short term."

The secret guards have all returned, and they have also brought back a lot of information.

Qin Ming had a general understanding of the number of Yan troops that could be mobilized.

The Yan army on the east coast numbered as many as one million.

Millions of troops were also stockpiled on the West Coast.

In the short term, even if all four pillars of the country come out together, they will not be able to gather many troops.

In other words, the current situation will not change.

However, the enemy's huge flaws were fully exposed before them.

As long as they seize this opportunity, they will catch the Yan army off guard and force them to flee in panic.

"Call the artisans from the army."

"Your Majesty, why are you looking for them again?"

Changbai Mountain is very strange.

"They are the key to resolving this battle."

Soon, several craftsmen were brought to Changbaishan.

Qin Ming sat on the city wall and discussed new weapons with them.

"Everyone, large-scale mass production in a short period of time is impossible."

"But I wonder if we could cast some of the shells we need ourselves?"

"Your Majesty... do you mean rubbing it with your hands?"

"That accuracy might be..."

Everyone present looked troubled.

It is true that they have advanced technology, but what Qin Ming is making now are new weapons and new ammunition.

If you rub it by hand, the accuracy may deviate to an alarming degree.

"It doesn't matter. A cannon can kill a mosquito. If you can't hit them, just rub out more."

"I just need to make a cannon and three hundred shells."

The cannon's extremely lethal straight-line penetrating shells could smash through the Yan army's city walls in one go.

With hundreds of cannonballs fired, even Wu Tianxing, who was hiding at the back, would be blown into the sky.

It just so happened that Qin Ming had already made nitro explosives, and now he had the foundation to make powerful artillery shells.

Seeing that they didn't dare to take action, Qin Ming took off his coat.

"Back in Lingnan, everyone made their first batch of weapons by hand. So much time has passed, and our skills have improved. Have you forgotten these simple things?"

"Let's go, I'll go with you all!"

Qin Ming wanted to do it himself and take the initiative.

This also motivated the craftsmen on site.

"Your Majesty, we will go with you!"

Everyone walked down the city wall.

Take out the cast mold and make modifications.

Then the bellows are pumped to start the fire, and the metal materials are put in to melt and blend.

Waves of heat emanated from the makeshift workshop, surprising the passing soldiers.

They began to discuss whether there should be new changes in the military camp.

"General Chang, what are we doing?"

A few curious soldiers came closer and asked Chang Baishan for information.

Chang Baishan said with a smile:

"I don't know either, but His Majesty always arranges some small gadgets before every war. Maybe they will be of miraculous effect on the battlefield?"

“That’s true when you think about it.”

In the past few days, many soldiers were a little scared when facing the Yan army, which was dozens of times larger than the Daqian army.

But Qin Ming, the commander, did not react.

Not only was he extremely calm, he even took out some new things to assist them in the battle.

This calmed the originally uneasy mood in the army.

"Your Majesty, is there anything I can help you with?"

Seeing that Qin Ming's actions had taken effect, Chang Baishan walked in to ask.

It just so happened that Qin Ming had already led his men to cast several shells.

So he picked up a thick gun barrel, mounted it on Chang Baishan's shoulder, and considerately stuffed two rubber earplugs into his ear.

"There is one thing I need your help with."

"You have strong internal strength. Can you use it as a support and carry it for two shots?"

Qin Ming wanted to see the lethality and penetrating power of the cannon.

But the cannon did not have a gun mount, making it inconvenient to move.

We can only let Changbaishan try it first.

"This...you really know how to order people around."

Chang Baishan smiled bitterly.

But he also understood that only a few people could do this job.

In the entire military camp, only he and Qin Ming had strong internal strength and could withstand the recoil of the cannon.

If other people came over, let alone lifting the gun barrel, the shock of the gun firing alone would be enough to shatter a person's internal organs.

"I won't let you go in vain this time. I will go with you."

Qin Ming, carrying another thick gun barrel, spoke excitedly.

It has been a long time since any weapon could make Qin Ming so excited.

"You're going too...?"

"Otherwise, you and I are the only ones in the entire barracks who can carry the cannon."

Qin Ming shrugged.

Seeing this, Chang Baishan said no more.

"So where are we going?"

"Go straight into battle and test the distance and power."

Qin Ming commanded the craftsmen to carry the existing artillery shells and follow him and Chang Baishan to the battlefield to record the effects of the new weapons.

Chang Baishan scratched his head and said:

"If you put it that way... I'll sacrifice my life for you."
