Hepo Town was the seat of Jiexi County in later generations, and as the name suggests, it is naturally in the west of Jieyang County, adjacent to Huizhou Mansion. The Fengshun camp is in the northwest of Xinheng Town in Jieyang County, and then north is Chengxiang County. There are two places here, and effective control can block the enemy from both directions.

However, Jieyang County was originally the first to send troops by Zheng Hongkui, and Zheng Hongkui should also be in charge of defense. In addition, Zheng Chenggong's army entered the Jieyang area, which also aroused the fear of Liu Gongxian and others. Although there have been no problems so far, they were still mentioned by Shi Lang.

Out of his heart, it is difficult to say whether he is opposing for the sake of opposition, because in the process of Zheng Chenggong sweeping the three counties in the southwest of Chaozhou, and then going north to Jieyang, Liu Gongxian and others did show full of defense. Especially when Zheng Chenggong swept the gray and white village, and Cai Yuan from Xinheng Town came to attach, the gate of the village was closed, as if facing a great enemy.

Another round of disputes, still inconclusive. In the final analysis, Zheng Chenggong's estimate is not Liu Gongxian, and even Huang Yingjie is worse, but in the final analysis, it is still his fourth uncle Zheng Hongkui, because once he wins these two points, Zheng Hongkui will be completely wrapped in the county. Between the two, there will always be some dislikes.

For this reason, Zheng Chenggong decided to go to Jieyang County to talk to Zheng Hongkui first. The next day, Chen Kai, Shi Lang and others followed Zheng Chenggong into the county seat.

After entering the city, Zheng Chenggong and Zheng Hongkui had a secret talk, and expressed their willingness to cooperate with the former's invitation, and the latter's willingness to cooperate with the soldiers into Hepo Town and Fengshun Battalion. Speaking of which, Zheng Hongkui's entry into Chaozhou is actually a month later than Zheng Chenggong, but it is not as good as Zheng Chenggong sweeping the southern part of Chaozhou, Zheng Hongkui was quite smooth at first, but when he occupied Jieyang County, he fell into the quagmire formed by the local tyrants, unable to extricate himself, and even the attitude of his original ally Liu Gongxian was changing.

Zheng Chenggong can be so smooth, in the final analysis, his own strength is stronger, coupled with the power of winning the Chaozhou capital city, heaven and man can be like this. And Zheng Hongkui only brought 3,000 soldiers and horses, and his prestige was not enough to shake or deter the local tyrants, so he could only slowly expand his territory like a turtle crawling.

"I said a long time ago, Da Mu is a thousand miles of my Shijing Zheng family, you have such ambitions, I support you."

"Thank you for your understanding."

"It's okay, there is no difference between our uncle and nephew."

Or when it comes to this, the little pimple from earlier has also disappeared. Next, Zheng Hongkui was more like a child getting a fun toy, and took out a treasure that he inadvertently picked up some time ago and showed it to Zheng Chenggong and others.

"This cannon, when I was inspecting the port one night, I vaguely saw something shining in the water, and when I went into the water the next day, I realized that it was a cannon. Originally, I thought it was just a cannon, but when I fished it out and really used it, I realized that it was a sacred object. As long as you sincerely pray before firing the cannon, you will definitely be able to hit the target, and you relied on this thing to make a threat when you attacked the new ruins earlier. ”

Zheng Hongkui stroked the cannon body made of red copper, and the color gave the soul, as if he was caressing the skin of his lover, and he saw Chen Kai's scalp numb. However, when he carefully recalled Zheng Hongkui's account of the origin and magic of this cannon, Chen Kai's eyes lit up.

"Spirit!"

Chen Kai's words blurted out, but Zheng Hongkui happened to hear them all over the place. I saw that he savored it carefully, and when he even slapped his palm, he praised: "Chen Shenjun's name is very good, it is called Lingjun, it is called Lingjun!" ”

Seeing Zheng Hongkui give his "new lover" a resounding name through Chen Kai's mouth, especially when he saw the excitement, Chen Kai couldn't help but break out in a cold sweat.

"What kind of mouth do I have, and I've become the father of the naming of the spirit gun."

The so-called spirit gun, in history, was fished out by Zheng Hongkui in the water of the wharf of Jieyang Port, and it is said that every time he prayed before the gun, he could hit 100 shots. This cannon, which later came into the hands of Zheng Chenggong, was also cherished, not only did he let the skilled craftsmen imitate him to create a secondary gun of the spirit gun, but also punished the spirit gun for falling into the water, and even executed the officer in charge.

"Can Xia Guan take a look at this door, um, Linggong?"

Even if he has too many mouths, Chen Kai feels that he should understand it, because he doesn't believe in things that can be achieved by praying at all, and he always has to figure out why.

Perhaps because of the father of the name, Zheng Hongkui did not show too much "jealousy" for Chen Kai. After getting the approval, Chen Kai approached the front, and before he could check it carefully, he noticed that there were really a pile of dense symbols placed there on the running body, without the slightest concealment.

Chen Kai's attention was suddenly attracted by these symbols, he really couldn't see what they meant, but the appearance of these symbols was clearly the letters derived from Latin, it was nothing more than that he didn't know which country it was and what it meant.

"The lower official dares to ask what language the Duke of Dingguo uses to pray?"

Once these words were said, everyone was puzzled, but like Zheng Chenggong, they obviously realized that Chen Kai must have discovered something to be like this.

"Does this make a difference?"

With a puzzled face, Zheng Hongkui replied very calmly, but Chen Kai asked next: "Yes, this cannon was made by Taixi, Dingguo Gong won't be our Chinese to pray, right?" ”

"It's made by Taixi, but I think that as long as you are sincere, the gods can understand it."

Terrible!

Zheng Hongkui said it as a matter of course, but Chen Kai was sweating profusely, so he simply stopped mentioning the matter, and directly asked Zheng Hongkui about the weight and range of the shell, but the answer he got was not beyond his expectations.

"24-pounder gun!"

As he spoke, Chen Kai nodded, and then learned about the precautions for the use of the gun from the gun crew, and soon found the gun gauge, gun ruler, degree plate and telescope from the gun commander's body.

"All of this was fished up with this cannon?"

"If you go back to Chen to join the army, they will all be fished together, and they have been tried many times, so they should be made together."

Artillery supporting measuring tools is already a common thing in Europe, but China's side has still entered a detour in the flow of experience. Fortunately, there were still many artillerymen who knew this kind of thing in the Ming Dynasty, which was a great achievement of the exchange between the East and the West, but it was a pity that it could not be passed on.

Hearing this, Chen Kai nodded, and then gave a large mound that looked very unapproachable, and asked the artillery crew to test fire in front of him.

Sure enough, the artillery crew aimed and loaded in the normal order, and the gun commander was fiddling back and forth with those few things, and constantly instructed his subordinates to adjust the angle of the artillery according to the results of the fiddling. After all the steps were completed, everyone actually bowed and prayed around the artillery, chanting words in their mouths, looking at that look quite sincere, even Zheng Hongkui looked like a matter of course.

The seal letter ignited, and the stinging stabbed like a frightened snake into the barrel of the cannon. In the next second, only a boom was heard, and the cannon body shook, and in the splash of sparks and gunsmoke, a black afterimage came out, crossed a perfect parabola, and then smashed directly on the big mound.

"This thing is really a fetish."

There was still a buzzing in his ears, and Chen Kai didn't hear who said this, but he always felt that it was Shi Xian's voice. However, he saw the scene just now, so he simply found an artillery crew from Zheng Chenggong's subordinates in front of Zheng Hongkui, Zheng Chenggong, Shi Lang, Shi Xian and others, and after determining the amount of gunpowder reloading, he simulated the scene just now and started resetting, aiming and loading.

"No one is allowed to pray, not even in the heart!"

After giving the order, Chen Kai asked for a wooden board and a piece of black charcoal, and while fiddling with those measuring tools, he used a carbon pen to write and draw on the wooden board, and even took time to observe the listless flag on the flagpole.

"The target that Xia Guan is aiming at is that mound."

Following Chen Kai's finger, a slightly smaller mound farther away than the mound just now had become Chen Kai's target. It is inevitable that the target will be smaller, the distance will be longer, and the hit rate will drop even further. Especially Chen Kai didn't let everyone pray, but he was even less favored by people after drawing ghost charms there for a while, and even Shi Lang and Shi Xian's brothers showed a look of looking at jokes.

After a long time, everyone was already impatient to wait, so Chen Kai stopped, breathed a sigh of relief, and asked the artillery crew to finish the final adjustments, and then gave the order to open the artillery.

To everyone's expectations, the artillery shook, and the afterimage of the black cannonball crossed the parabola, and it really hit the mound as Chen Kai pointed out, which immediately attracted everyone's jaw-dropping.

"I didn't expect it to be like this."

Zheng Chenggong smiled excitedly, but the Shi brothers couldn't laugh anymore. Seeing this, Chen Kai also bowed, and then explained: "This is mathematics. ”

In fact, for the parabolic formula, Chen Kai also returned it to the math teacher early. Fortunately, the truth is not completely useless because one or two formulas are forgotten.

Chen Kai had just watched a round of test firing, relying on relatively accurate measurement tools to re-derive the formula, and some vague impressions reappeared in his mind one stroke at a time. Then, on the other hand, by measuring tools and formulas, we can get a data that is comparable to rich experience. After all, a starting point is the origin, there is a clear angle and the length of the horizontal axis, what to seek, it is not undone when I swept the question bank to cope with the exam, but the impression has long been blurred.

But in the final analysis, it is still the casting of this gun, and the supporting measuring tools are also extremely fine, which is really a rare boutique, otherwise any mistake or omission will be a huge difference. At the end of the day, mathematics is an extremely precise science, not something to be played with.

Chen Kai didn't know whether the accuracy of this cannon was accidental or the handiwork of a fine craftsman, but just as he continued to try to understand a thing or two in detail, Zheng Hongkui was shocked that Chen Kai was able to accurately hit the target for the first time under the command of the artillery crew, and soon gave a statement that could make everyone happy and convinced, so that Chen Kai choked so much that he couldn't say a word.

"Chen joined the army and prayed in his heart."
