Boom, boom, boom.

In a wasteland behind Tuchengzi City, every once in a while there was a deafening loud noise.

It was the sound of an explosive bag trying to explode.

"Boom",

With a loud bang that far exceeded the previous sound, a large crater appeared out of thin air in the wasteland. The rubble that had been specially stacked on the explosive packs was blasted into the air, crackling the armor placed next to it.

"General Zhang, this power should be enough, right?"

Looking at the explosives bag from a distance, Zhu Youzhen put down his hands covering his ears and asked Zhang Pan with a smile.

Without answering, Zhang Pan quickly rushed into the smoke that had not yet dissipated, and quickly flipped through the armor used for the experiment.

After a while, Zhang Pan's excited voice came from the smoke of gunpowder: "Enough." Your Highness, the power of this one is definitely enough. ”

Finally enough.

The stone in Zhu Youzhen's heart was finally put down.

This was the last explosive pack tested, and if it wasn't powerful enough, he would have to abandon the plan.

Zhu Youzhen asked the Lushun Ming army to prepare a total of five explosives bags, which were 1 catty, 3 catties, 5 catties, 10 catties, and 20 catties of charges.

Out of Zhu Youzhen's poor knowledge of firecrackers in his previous life, these explosives bags were not wrapped in cloth, but all wrapped tightly with fur. After all, the tighter you tie it, the louder it will explode.

In the explosion test, the explosive package with a charge of less than 10 catties was not powerful enough to pose a fatal threat to the Tartars.

Only this largest explosive bag, which contained 20 catties of black powder, passed Zhang Pan's assessment.

Is it enough to have such a great power?

What exactly is the evaluation of the plate?

Approaching the explosion site, Zhu Youzhen looked at the messy scene, and felt that there was something wrong with Zhang Pan's assessment.

The first thing Zhu Youzhen saw at the scene of the explosion was the large crater half a meter deep and nearly 2 meters wide.

Being able to blow up such a large crater, even if there is a reason for the soft soil of the wasteland, can fully prove the power of the explosion point. It is estimated that if someone is at this explosion point, no matter how thick the iron armor is, it will be blown apart.

And the mottled marks on the armor around the explosion point also clearly marked the effective radius of the explosion. In this area of almost 20 meters, the armor was damaged to varying degrees.

Of course, the closer you get to the explosion point, the more the armor will be damaged.

Wrong.

This 20-meter killing range should not be the limit of the explosion.

These 20 meters is the damage range caused by the debris collapse, and if the outer layer of the explosive package is covered with some nails and broken iron, the damage range caused by the explosion should be further expanded.

Zhu Youzhen stared at the scene of the explosion, and his mind kept calculating.

"Your Highness, this is definitely a genius idea."

Looking at Zhu Youzhen, Zhang Pan's dusty face was full of undisguised appreciation.

"This kind of explosives bag, the lowly will immediately arrange to make a few more.

Haha, the next time the Tartars come back to attack the city, they will be able to taste the power of this explosive pack. Haha, haha. ”

"General Zhang, now that you have such a sharp weapon in your hand, you still don't dare to go out and do a vote?"

Hearing the meaning of Zhang Pan's words, Zhu Youzhen frowned. The question in his mouth did not return to its former calmness, and became a little aggressive.

"Your Highness,"

Seeing that Zhu Youzhen was angry, Zhang Pan couldn't care about tasting Zhu Youzhen's arrogant words, so he hurriedly explained: "Your Highness, this kind of explosive bag weighing more than 20 catties can't be thrown far by manpower.

If you don't use the height of the city wall to throw it down, you will definitely be injured along with the user. With this flaw, this explosive pack cannot be used in field battles except for killing and injuring the enemy troops under the city when defending the city! ”

"Stupid."

Can't fight in the field? Zhu Youzhen almost laughed at Zhang Pan's stupid words.

It is no wonder that only 20 pounds of explosives passed the evaluation of Zhang Pan, which turned out to be tested by breaking the heavy armor of the Tartar.

With such a powerful explosive package, it can't be used in the field, and this brain is really ridiculously rigid.

"Who said explosives packs could only be thrown out? Aren't we just putting it on the ground and exploding right now? ”

Looking at Zhang Pan, who was a little dazed on his face, Zhu Youzhen simply put out all the plans he envisioned.

"General Zhang, didn't the Tartars begin to retreat?

With so many Tartars, there will certainly not be too many paths they can take in their retreat. It shouldn't be difficult for you to find out the way for the Tartars to withdraw, right?

Say, "If we go in front of the Tartars by boat, and bury a few or a dozen packets of explosives in the path of the Tartars, and wait for the Tartars to pass by......"

Zhu Youzhen made a gesture of exploding.

"By then, how many Tartars do you think we can blow up?

General Zhang, 100 Tartars shouldn't be difficult to reach, right? ”

Zhu Youzhen's words were like a thunderbolt in the clear sky, shaking Zhang Pan's head and head began to buzz, and the whole person felt a little dizzy.

How else can it be done?

Zhu Youzhen's words opened a door that Zhang Pan had never thought of, and his thinking instantly entered a new world.

It's a pity, it's a pity that this explosive bag is not easy to ignite, and at most it can only blow up the vanguard of the Tartar pathfinder. It would be nice if you could explode on time at will. Then there is hope of blowing up Mang Gurtai.

In an instant, Zhang Pan thought of a new application method for several explosive packs from King Xin's imagination, and his face suddenly became extremely exciting.

"General Zhang, General Zhang?"

Zhu Youzhen's cry woke Zhang Pan from his contemplation.

When Zhang Pan came back to his senses, the first thing he did was to respectfully bow to Zhu Youzhen.

"Thank you, Your Highness, for your advice, Zhang Pan is confused.

Your Highness, and let Zhang Pan prepare well.

His Royal Highness is right, with such a sharp weapon in hand, the plate must be a big ticket, and leave an unforgettable memory for the Tartars.

Your Highness, Zhang Pan will definitely make the Tartars remember this time - ruthless. ”

Looking at Zhang Pan, who was obviously performing the disciple ceremony, his spirit and spirit had been significantly improved, and he was about to speak incoherently, Zhu Youzhen smiled happily.

This state is the main commander behind enemy lines I want.

With the explosives pack as a means of attack, Lushun can now really be regarded as a henchman of the Tartars.

In the evening, on the dock of Lushun Nancheng, watching the Ming army carefully move more than 20 explosive bags into the cabin, Zhu Youzhen's heart couldn't help but be a little upset.

This time, he was literally sitting on the explosives bag.

More than 20 explosives packages, even if the power of black powder is small, if these hundreds of catties of gunpowder are exploded at the same time, then the ship will definitely end up in pieces.

"Your Highness, you really don't need to accompany us on an adventure, you might as well stay in Lushun, right?"

Seeing that Zhu Youzhen's face was a little pale, Zhang Pan persuaded with concern: "If you have to go, then you can change ships?" ”

"No, Lone believes in your General Zhang's ability. There are only a few dangerous goods, I believe you can still manage it. ”

Although there was some hair in his heart, Zhu Youzhen still reluctantly allowed himself to show a smile.

No matter how scared we are, we have to hold on no matter what.
