"Qin Yunfei, you don't pretend to be here! In your heart now, you are already scared to death! My mermaid army has 30 million!"

When Long Thirteen talked about his family, he was excited, after all, their family, not to mention the Chaotic Star Sea, even if the sea area was expanded ten times, they could easily control it.

Therefore, he didn't believe that Qin Yunfei would not be afraid at all.

And when he used such an identity to suppress Qin Yunfei, Long Thirteen's face also had a lot more arrogant smiles.

"Qin Yunfei, if you are willing to kneel down and apologize to me now! I can spare you from dying! I can even give you an official and a knight!"

Seeing Long Thirteen's smug expression, Qin Yunfei suddenly felt that this guy was an idiot-like dog, and there was no need to talk nonsense with him at all.

So, he picked up a mess of cloth from the ground and stuffed it directly into the mouth.

and instructed Xiang Wentian on the side, "Remember to give him something to eat on time, if you want to exchange it for your seventh princess, this guy is an indispensable prop." ”

After Qin Yunfei's simple reminder, Xiang Wentian hurriedly nodded in agreement.

"Yes! ”

Seeing Qin Yunfei's methods just now, Xiang Wentian also began to worship Qin Yunfei.

Seeing that Xiang Wentian's expression had changed, before Qin Yunfei left, he told him to be ready, and wait until tomorrow to negotiate with the Emperor of the East Island.

This was a negotiation that would decide their life and death, and Qin Yunfei naturally wouldn't go there in person.

After all, now the only ones who can really influence the situation of the battle are him and Princess Longqi, and now that Princess Longqi has been arrested, in case she is also controlled by the other party, then this battle will be over before it has even started.

While letting Xiang Wentian prepare, Qin Yunfei also returned to his laboratory and started a new job.

There was only one result of going to Wentian to negotiate, that is, the Emperor of Dongdao exchanged the Seven Princesses for Dragon Thirteen.

It's not that Qin Yunfei is accurate, but he knows that the Dragon Seven Princess is really nothing in the eyes of the Emperor of the East Island, and she doesn't even have the identity that a daughter should have.

In exchange for his approval among the mermaids, the Emperor of the East Island would inevitably agree to replace Qin Yunfei with the Seventh Princess, whom he didn't care about.

After calculating all this, Qin Yunfei was even more anxious to prepare sharper weapons.

In the Cidao area, there is a lack of sufficient fuel resources, and now all the refining work is also carried out in accordance with Qin Yunfei's set of photovoltaic hydrogen training methods.

However, in the face of the tens of millions of troops that Long Thirteen told, the armaments and materials he needed could not be done with just these hydrogen.

So, he needs to design more powerful weapons.

And as soon as he entered the door, he began to think in his mind, those simple mechanical weapons.

However, if he had to face so many enemies, Qin Yunfei still couldn't think of what kind of weapons he could use to accomplish this arduous task.

Today, he had enough cruiser ironclads, but not enough men to pilot.

If an army of tens of millions of mermaids surrounds itself, even if it uses a bow and crossbow, it will not be able to deal with so many people, after all, it is easy to make a bow and crossbow, but tens of millions of arrows cannot be done.

So, thinking of this, Qin Yunfei was in trouble.

Just when he was distressed, Lin Feixue suddenly screamed, and then bit his hand and walked over.

"Yunfei, this magnetic induction is really troublesome. I don't even know what I'm doing. ”

Qin Yunfei's eyes flashed with hope, he clapped his hands violently, and said excitedly, "Yes! If it's a magnetic cannon, even if there are more people, you won't be afraid!"

"Magnetic cannon, what is that?" Hearing about the magnetic cannon, Lin Feixue was also a little curious.

Although the magnetism is magical, Lin Feixue also found many flaws in it.

For example, magnetic force can only exert force on iron products, but on ordinary metals, there is no such special force.

Therefore, if magnetic force is used to create large-scale weapons, how powerful is the real one, Lin Feixue is also very skeptical.

But Qin Yunfei can always surprise people, so Lin Feixue at this time, to a certain extent, is also very curious, wanting to know how powerful this magnetic force can be, and it can create a magnetic cannon.

"Ordinary magnetic force naturally does not have such a powerful force. However, if the magnetic fields are superimposed, they can create a hundredfold, or even tens of thousands, of magnetic force. When a certain limit is reached, the gravitational coefficient can be changed. Therefore, the real power of the magnetic cannon is not the magnetic induction effect brought by itself. The scariest part is to create a gravitational hole!"

Qin Yunfei just made a simple explanation, after all, what it contained, without a model, it was difficult for him to explain clearly.

Moreover, when exerting a strong magnetic force, even if the critical point is not reached, the interference of the magnetic force alone on the electric current in the living organism is not something that ordinary people can bear.

There are tens of millions of mermaid troops, but they can't just come up with tens of millions of people to besiege such a small island, right? When they are besieging this side, having 120,000 people is already very remarkable.

Therefore, the magnetic cannon should be used for interference, and at the same time, a high-pressure magnetic device should be used to carry out magnetic impact in the concentration area of the opponent.

If nothing else, Qin Yunfei felt that he could even dispose of the other party with zero consumption.

Thinking about this layer of relationship, how could Qin Yunfei stop?

He picked up the drawings, drew new equipment drawings with flying blocks, and at the same time instructed Lin Feixue to notify the other alchemists to do a good job of building the new equipment.

In the three days that Xiang Wentian went out to negotiate with the Emperor of the East Island, Qin Yunfei quickly completed the preliminary construction, and by the evening of the third day, they had already built eight magnetic particle cannons.

The purpose of this weapon, in Qin Yunfei's opinion, in addition to being able to release a super strong magnetic field during combat, can also be used as a particle accelerator even in daily life, which will be of great help to future experiments.

And that night, Qin Yunfei spent a full eight hours installing all the equipment.

It's just that when everyone saw these strange-looking things with spiral magnetic coils, they all showed solemn looks.

"Master Qin, these things, without any Star Soul Crystal as a base, can they really unleash super power, can they deal with those mermaid armies?"

Everyone is wondering, after all, this kind of thing, without a blade, without a sharp gun, no matter how you look at it, it is impossible to achieve combat effect, right?

However, in the face of everyone's suspicion, Qin Yunfei smiled, and he pointed to the distant white sail on the sea level.

"Our enemies are coming soon, and you, for now, doubt what I've designed. ”
