Compared with other city defense equipment, a sky-shattering thunder thrown over can not only destroy the siege equipment, but also cause huge damage to the Qing army.

Gao Yihuan felt that it was much better to give this thing than to sell gunpowder directly.

Li Zicheng took gunpowder, that is, put two cannons, and used it to burn the siege equipment, and the effect was naturally not as good as the earth-shaking thunder.

Gao Yihuan took Zhou Ronghua, and after seeing the two earth-shattering thunders, Zhou Ronghua was quite excited, and he hurried to Guanzhong without returning to Jingzhou.

Under Gao Yihuan's boasting, these two earth-shattering thunders became his main weapons to defeat the Qing army.

Zhou Ronghua felt that he had mastered the secret of Wei Wujun and repeatedly defeated the Tartars, and returned to Guanzhong excitedly.

Although this earth-shattering thunder is too expensive, Zhou Ronghua decided that he must be persuaded to buy a large number of Li Zicheng.

After sending Zhou Ronghua away, Gao Yihuan returned to the mansion and invited Gao Yicheng to meet.

"Marshal looking for me?" Gao Yicheng entered the study and saw Gao Yihuan sitting at the table, writing a letter.

Gao Yihuan saw him come in, motioned for him to sit down, and waited for him to finish writing the letter, dry it and put it in the envelope, before he looked up and said: "Yicheng, give this letter to Ma Hongshan, and tell him that Ben Shuai is willing to buy sulfur and fire sulfur twice the market price." Let him find a maritime merchant from eastern Zhejiang and smuggle a batch of sulfur from Japan. ”

The sulfur mines in Luanchuan County were attacked by the Qing army, and the output dropped sharply, if it were not for the fact that it was located in the mountainous area, the Qing army would have sent troops to wipe it out.

Gunpowder is also in urgent need for Gao Yihuan, and if he wants to sell it to Li Zicheng, he must open a new source of raw materials.

Maritime merchants in the southeast love money, and smuggling is not legal in the first place, so naturally they don't care who buys it.

Gao Yihuan took the letter and nodded, "Let people do it!" ”

"There's one more thing I want to tell you!" Gao Yihuan stopped him, and then ordered: "Ben Shuai entrusted the relationship with the governor He to get a few road guides, you personally go to Guangdong, and go to Macao to hire a few Portuguese for Ben Shuai to come over." ”

"Portuguese?" Gao Yicheng was confused.

Gao Yihuan said, "It's the Franc man, these Xiyi cannons have two brushes, and the workshop needs their skills." ”

Gao Yicheng knew about the Franc machine, but he was still a little worried, "Dashuai, Guangdong is so far away from us, is the Franc machine willing to come?" ”

Gao Yihuan said in a deep voice: "No matter what they ask, you will agree, and they promise to come." ”

"If these foreigners ask for a price, do you want to agree?" Gao Yicheng frowned.

Gao Yihuan said: "Promise, get the turtle grandson first, and talk about the rest later." ”

The technical content of this thing is not high, and Runing's workshop has only improved it slightly, using thin iron sheets to wrap more gunpowder, adding more fragments to increase the power, and others can imitate it.

As soon as Gao Yihuan waited for Gao Yicheng to leave, he asked Liang Yizhang to return to Runing, urged the workshop to step up the production of earth-shaking thunder, and at the same time allocated 30,000 taels of silver to Chen Huiting to cast long-barreled copper cannons and began to improve the flowering shells of the Ming Dynasty.

In the war, various technologies will inevitably develop rapidly, and even the Manchu Dynasty's cannon casting technology can surpass that of the Ming Dynasty, so you can know the stimulation of war on technology.

Since this earth-shattering thunder was sold to Li Zicheng, someone will definitely imitate it, Gao Yihuan can't let others use this thing to hit him again, so he must create a new weapon before others catch up to restrain the imminent threat.

After giving these instructions, Gao Yihuan's energy returned to the training of the new soldiers.

In mid-August, the new soldiers had been training for more than two months, and in another half a month, they would be able to have a certain combat strength.

On this day, in the New Army camp outside Jingzhou City, Gao Yihuan stood on a hill with Jin Shenghuan and other generals.

Zhao Daxian walked up from the slope with his helmet and sword, and saluted with a smile: "Qiqi Marshal, today's new pawn is training for siege warfare!" ”

Gao Yihuan bowed slightly, looked down from the hill, and saw that not far from the school grounds, there was a section of earthen wall for training, but it was not high or very long, but there was a moat in front of the wall, which was a miniature version of the city.

Jin Shenghuan on the side explained: "Marshal, after the new pawn is trained, there are only two main tasks, one is to defend the place, and the other is to assist the main force to attack the walled city. These two tasks are inseparable from siege and defense, so one of the main training of new pawns is to practice siege and defend the city. ”

At this point, Gao Yihuan heard Jin Shenghuan say that the new pawns could not fight in the field, so he simply practiced less field battles, stationed them in the local garrison, liberated the old battalion soldiers from the local defense, and then clenched them into a fist, who will fight whom.

Gao Yihuan agreed with this plan very much, he bowed slightly, "It's okay to train like this, just after training, pull directly to Yiling and take down this main road out of Sichuan." ”

Yiling is in the hands of the Western Army, which makes Gao Yihuan always feel a little uneasy, and he must take it down as soon as possible.

At this time, on the school field, the two teams of men and horses for attack and defense were ready, 500 soldiers stood on the city to defend, and 1,000 soldiers attacked from below.

Since the implementation of the rules of rotational combat competitions, there has been competition everywhere in the Wei army, and even the training of new soldiers is no exception.

At present, these two teams, the winners of attack and defense, are in the final round of duel.

Although it was a drill, the soldiers held wooden guns and shields, but one by one they still stood straight, their expressions solemn and murderous.

Gao Yihuan could see that after more than two months of training, these homeless people did have a bit of an army appearance.

At this time, the drum of "Dong Dong Dong" sounded, and the soldiers of the attacking side, the soldiers in the front row raised their shields to their chests, and the soldiers in the back row raised their shields above their heads, and then marched in a neat step and advanced towards the city wall in formation.

The archers on the head of the city drew their bows and arrows, and shot a rain of arrows at the city.

These arrows have no arrows, the front is wrapped in cotton cloth, stained with white ash, and the soldiers must retreat after being shot, otherwise they will be found by the magistrates, they will have to eat military sticks, and the whole team will be eliminated directly, so the soldiers are very strict with the rules of the drill.

The real war is more complicated than this kind of drill, and there are many more equipment, but after such repeated drills, when the soldiers attack the city again, they are always much stronger than the unprepared.

This is Gao Yihuan looked at the offensive and defensive sides, both of which were quite disciplined, and he was still quite satisfied in his heart, so he smiled and said to Jin Shenghuan on the side: "After half a month's training of new soldiers, the war will come to an end." Before asking Huchen to write a plan for the formation and training of the five armies, the commander has already read it, and plans to elect the chief general of the five armies in the near future to complete the reorganization of the army. ”

Saying that, Gao Yihuan stared at Jin Shenghuan, "Huchen has worked hard for this matter, and the training of the new soldiers is also good, and he will definitely be one of the main generals of the five armies at that time." ”

"Humble position, Xie Dashuai cultivates!" Jin Shenghuan instantly clenched his fists with joy.

Zhao Daxian and the others on the side pricked up their ears to listen, and their eyes flashed in an instant, and he looked at Gao Yihuan's side face with anticipation, as if to say, what about me? What about me? Say me!

Gao Yihuan turned his head and saw that he was looking forward to it, and couldn't help but be slightly stunned, but his eyes immediately turned into the distance, and he suddenly smiled: "Look, it's attacked!" ”
