Within a few days, Li Zisheng received a reply from his friends scattered all over Central, all of whom agreed to meet in Yangzhou in mid-July to hold a national congress of the Iron and Blood Youth League.

Originally, they were going to go out early and go to Yangzhou for a walk first, after all, the two of them had never been to Yangzhou, the most prosperous city in Kyushu in Central Continent.

However, at this juncture, the Qingyang Sect of the East China Sea suddenly came to the alarm, and the Sea Clan in the East China Sea suddenly had an abnormal movement, so the disciples who were on the field duty, especially the disciples in the strongholds of the coastal cities, must be on guard in place, and if there is anyone who escapes from the battle, there will be heavy punishments.

Of course, this sect not only came to warn, but also recruited disciples from the sect to rush to various places to take precautions.

Originally, Canghai Shipyard, as a seagoing shipbuilding workshop, also had to send high-ranking people to sit in the town, but I don't know if it was just a small shipyard that was not taken seriously, or if there was too little manpower, and the Qingyang Sect didn't send anyone here.

Well, strictly speaking, it's not that no one was sent, it should be said that someone has already been sent, so naturally it is Liu Wuflawless who is uninvited. The sect made up a dispatch order, and the flawless singer and several of her little sisters became reinforcements for the Canghai Shipyard.

At this time, Li Zisheng came to the fore, and this Senior Sister Liu and her "popularity" were not very good.

Liu Wuflaw's original "popularity" is naturally quite good, and there is no problem for those suitors here in Qingzhou to get together to strengthen the platoon. But after Li Zisheng's force in the "Battle of Half Street", coupled with her openly running to Canghai Shipyard and Li Zisheng's "double residence and amphibious", this "popularity" became bad.

In fact, this is Li Zisheng's bad thinking. It's not that those suitors are discouraged and unwilling to come over to become the guards of the flawless singer, but that there are people in the upper echelons of the sect who are not used to these two little guys. That's why I deliberately didn't arrange people to come.

But this doesn't mean that the two of them are going to be killed, after all, if you can't beat them, can you escape? So Li Zisheng and Liu Wuflawless are not very anxious.

It is not uncommon for the Sea Clan to infest the coast of Central Continent, otherwise why would the Qingyang Sect set up so many magic circles, with these magic arrays, the Sea Clan Demon Beasts will definitely not dare to go deep into the inner 6, and even the towns along the coast will be difficult to break. Their main threat is the safety of shipping lanes.

Speaking of which, the most unfortunate are the merchants who transport by sea. No matter how strong their sea ships are, no matter how high the cultivators on them are. They are also unwilling to face the infestation of the sea tribes at sea.

The second is a shipyard owner like Tian Kewang. As a shipyard, it's cost to consider, so there aren't many circles here. Because it doesn't cost much to set up the array, the annual maintenance cost is a considerable amount.

In addition to the highlands where they lived, the docks, storage yards, and shack areas along the coast were not protected by magic circles, let alone the sea clan demon beasts at that time. Even a tsunami would be devastating.

So the owner of the field factory could only come to Li Zisheng and Liu Wuflawless with a sad face to find a way. According to the mind of Li Sangongzi. In fact, as long as the project is stopped, all the people here can be relocated to Inner 6 to hide for a while. But Tian Kewang refused to say anything.

Thinking about it, the progress of his project is already slow, and if he stops work like this, he will definitely not be able to complete the quota of thirty sea ships agreed with the sect. Li Zisheng had to think of another way, even if he didn't plan for this profiteer, he had to plan for the mortal craftsmen who worked in this place.

He racked his brains for a long time, but he didn't think of any idea for a while. The characteristic of the sea clan demon beast is that it is strong and does not lose, which was during the great invasion of the demon god. Li Zisheng already knows the "satellite image" inside the water Yao star chariot.

Unless he now has ready-made shore defense artillery on hand and a couple of batteries at key points. Otherwise, with his and Liu Wufang's strength, it would be a joke to deal with those large Sea Clan demon beasts.

Wait, shore defense artillery......

Li Sangongzi suddenly remembered the Red Flag system in his mind, and the internal system of the Liberator Legion was full of planetary-level weapons.

Thinking of this, he immediately entered a state of settling down and came to the fantasy space where the Red Flag's personal information terminal was placed.

Sure enough, this place is still the same, and there is no other furniture in this imaginary study except for a table and a chair.

In fact, Li Zisheng was quite diligent when he first obtained this system, but unfortunately due to "network problems", except for military knowledge, other information is still blank. And he won't be able to use this military knowledge for a while, and his usual schedule is full, so he hasn't put much effort into it. I don't come here very often, except for the occasional weapon information.

And he was still quite jealous of that Mr. Heavenly Demon, so he was not completely at ease with the "gift" it gave.

But at this point, he can't afford not to come in and read the information.

The planetary-level weapons are indeed complete, and Li Zisheng didn't take much effort to show the most suitable weapon for the current situation, that is, the electromagnetic railgun!

Electromagnetic cannon is an advanced kinetic energy killing weapon made by electromagnetic shooting technology, unlike the traditional cannon that acts on the projectile with gunpowder gas pressure, the electromagnetic cannon is the use of the force of the electromagnetic field in the electromagnetic system, and its action time is much longer, which can greatly improve the degree and range of the projectile. The railgun is the most common style of electromagnetic gun.

The railgun (RAI1gun) or the magnetic railgun, railgun, in our world by the Frenchman Villerouub in 192o, is to use the ampere force of the interaction between the orbital currents to shoot the projectile.

It consists of two parallel long straight guides, between which a smaller slider is placed as a projectile. When the two rails are connected to the power supply, a strong current flows in from one guide rail, and when it flows back from the other guide rail through the slider, a strong magnetic field is generated between the planes of the two guide rails, and the current slider will be shot out in a large degree (theoretically up to matte) under the action of ampere force, which is the shooting principle of the railgun.

The advantage of the electromagnetic railgun is that it is easy to make, and it can be made large without difficulty, as long as there is enough space and conductive materials, there is simply no upper limit to the power of this weapon. The matte is a bit exaggerated, but it's not too difficult to get the tone. Unlike large artillery there are technical limitations.

So under the auspices of Li Zisheng, a large electromagnetic railgun was built in the Canghai Shipyard, which was located on the high ground next to the shipyard. Several houses were demolished to erect the cannon.

However, for the safety of the shipyard, Tian Kewang and the owner of the factory still reluctantly agreed. (To be continued......)
