When Lin Chong met Duan Jing and bought a horse, on the big island of Liangshan, a well-guarded base was being guarded by the heavy cavalry on his back.

Wen Huanzhang, who was in charge of the internal affairs of the Liangshan Army, and Xu Guanzhong, who was in charge of strategic military and foreign affairs, also deliberately took time out to visit the test site in person.

The two were actually a little worried about Lin Chong's plan and felt that it was too risky, but Lin Chong was full of confidence.

Therefore, the two of them were also very curious, and wanted to see how powerful the secret weapon Lin Chong said.

"Two military advisors, everything is ready, can we start?"

In a sunken valley on the mountainside on the outskirts of Wanzi City, Ling Zhen ran over to the two of them for instructions.

"Let's get started."

Wen Huanzhang looked at the wooden stakes covered in iron armor thirty steps away, nodded and ordered.

"Please also ask the two military advisors to follow Master Li to the back of the wall."

Wen Huanzhang was slightly stunned, and listened to Xu Guanzhong say: "Is it still dangerous to be so far away?" ”

Although Xu Guanzhong has never been a soldier, he also knows that there is a weapon called "Thunderbolt Fireball" in the Great Song Dynasty Forbidden Army.

There is a record in the "General Essentials of the Martial Arts" that this kind of thunderbolt fireball is wrapped in a bamboo tube about one and a half inches thick, and the outside is wrapped with three to four catties of gunpowder and broken porcelain and broken iron.

Leave a tube about an inch long at each end of the ball so that one end can be used as a handle and the other end can be used as a hand-held handle, and the other end can be used for gunpowder and twisting.

When used, you only need to ignite the powder twist and throw it hard, and it will explode like a thunderbolt, shooting out broken porcelain and broken iron pieces mixed in the gunpowder to kill the enemy.

However, despite this, Xu Guanzhong has also heard that this kind of thunderbolt fireball is just a very loud sound, and the effective killing distance is only about two zhang, and no matter how far it is, it will purely rely on the sound and fire to frighten the enemy.

Now that he and the others were thirty steps away from the wooden stake, it could be said that it was already a very safe distance, and they even had to hide behind the wall.

Ling Zhen nodded and said, "The military advisor doesn't know, we use a new type of gunpowder, which is more than twenty or thirty times more powerful than the gunpowder used by the Great Song Forbidden Army.

Moreover, our gunpowder is specially treated and sealed in iron sheets. Therefore, although the charge was much less than the thunderbolt fireball used by the Great Song Forbidden Army, the power was more than ten times greater.

According to the military master's estimates, as well as the data from our previous thunderbolt tests, the effective killing distance of this new grenade should be about five paces, and the distance of fragmentation can be up to fifty steps.

Therefore, the position where the two military advisors are standing now is also unsafe. ”

Both of them were a little stunned for a moment, what Ling Zhen said was really too much for them to imagine, and they had to doubt its authenticity.

But they didn't dare to believe it, because Lin Chong had brought them too many magical and incredible places.

So the two of them cooperated very well and followed Li Ming to the back of the wall in the distance, and looked out from the position of the battlement, and saw that at this time, Ling Zhenzheng asked everyone around to hide in the trench bunker.

At this time, he saw that Ling Zhou was holding a wooden grenade almost the length of a person's palm in his right hand, lit it with the fire fold in his left hand, stayed in his hand for a while, and then threw it hard at the wooden stake in the distance, and then he himself jumped into the trench behind him quickly.

I didn't wait long, I heard a loud bang, like a thunderbolt on a sunny day, and saw a burst of white smoke rise, along with the white smoke rose into the sky, and a large amount of sand and stones, broken armor.

There is also the entire iron-armored wooden stake wearing the Great Song Dynasty Forbidden Army, and the wooden stake with thick legs and stomach was actually blown off by the roots, and flew into the air, almost more than one person high.

What was even more frightening was that there was a piece of broken iron that flew more than forty paces away, hit the wire mesh fifteen steps in front of everyone, and then directly stuck to it.

Wen Huanzhang was stunned for a moment, Rao was mentally prepared, and at this time he unconsciously took two steps back, only to feel that his ears were buzzing, his heart was pounding, his mouth was open, and his chin was about to hit the surface of his feet.

And Xu Guanzhong's heart also jumped wildly, looking at the wooden stakes flying into the air in the distance, as well as the shallow pit on the ground after the smoke cleared, and the broken iron pieces on the wire mesh not far ahead.

At this time, he had only one thought in his heart, fortunately, he was as good as a stream, if he insisted on standing thirty steps away, if this fragment flew to his face, he would break his appearance if he didn't die.

At this time, Ling Zhen and the others had already crawled out of the trench bunker and came to the test site, and Wen Huanzhang and the others also hurriedly got off the fence and ran over.

I saw that at this time, a shallow pit with a diameter of seven or eight feet and a depth of about one foot had formed in the center of the explosion, and the wooden stake closest to the shallow pit was blown off one by one, and the armor of the wooden stake was also blown to pieces;

One of the wooden stakes a little farther away from the shallow pit was blown to the side, and the Song Army-style half-body iron armor worn on the wooden stake was also damaged many times, and several holes were blown up, and the leather lining the armor was scorched by the flames of the explosion, emitting an unpleasant scorching smell.

Wen Huanzhang and the others were shocked and speechless. This time it was a wooden man, and if it was a living person, it would definitely be blown apart, and the dead couldn't die anymore, right?

Haha, this is the real gunpowder, the huge and useless thunderbolt fireball of the Great Song Forbidden Army is a joke in front of this new grenade!

Xu Guanzhong swallowed a mouthful of saliva vigorously and said excitedly: "I didn't expect the power of this new thunderbolt to be terrifying!" Brother Ling Zhen, this kind of ...... Well, can we mass produce new grenades? ”

"Yes, this grenade is actually quite simple in construction and easy to produce.

The warlord is still trying to find a way to develop a fuse mechanism that will not need to be ignited at that time, and will explode as soon as he pulls the cable and throws it out. This is not only several times more convenient than it is now, but also can be used immediately. ”

The two couldn't help but smile at each other, the Dark Dao military master is really a man of destiny, and he can always bring shocks and surprises to everyone, with this kind of grenade that can be used immediately, this trip to Liao should be worry-free.

The test was carried out again, Ling Zhen found another pig and a sheep to do the test, put on iron armor on them, and threw the grenade at a distance of four or five steps from them, and after a loud bang, they were all killed.

Wen Huanzhang and Xu Guanzhong watched for a while, and left satisfied.

"Mr. Wen, have you thought about it, if what Brother Ling Zhen said is true, if this new type of grenade can really be mass-produced, what will the future combat look like?"

Wen Huanzhang thought for a while, shook his head and said: "I can't imagine, if this is the case, then my Liangshan Army can really be invincible in the world!"

In the face of such grenades, any impregnable military formation or fortress would be a joke.

Because we also have trebuchets, we can use trebuchets to throw a lot of grenades at enemy positions, think about it, what is that scene? ”

"It must be invincible, invincible!"

Xu Guanzhong's excited eyes lit up, looked at Wen Huanzhang and said: "You and I are so fortunate to be able to assist such a lord and achieve a great cause that will shine for a thousand years, and the Liangshan Army will surely prosper in the world!" ”
