Before Li Ang could take a few steps, the mermaid girl suddenly turned her head to look at his position, only to see her cherry mouth slightly open but no sound came out.

However, Leon felt a great threat, and his figure flashed rapidly, and while pulling away, he circled around the mermaid girl's side and back.

Although he has remained hidden in the rain, the mermaid girl has always been able to find his place, and invisible sound waves sweep in, making people dizzy even if they touch it at the slightest touch.

It turned out that the mermaid girl's sonic attack contained a powerful spiritual impact, and if it weren't for Leon's mental power, which was also strong, he would have died of a mental breakdown in the previous attack.

His own condition is not good, his whole body is weak, and his chest is constantly falling scum, but on the other hand, the other party is in full strength, and the shark warrior is also recovering quickly in continuous healing.

Li Ang no longer hesitated at the moment, and disappeared into the sky in an instant with the help of the cover of the rain curtain.

Xiao Jin flew directly to Jinling with the people of Yushan Town, while Li Ang flew to the Gusu base, which was the first human survivor base he had ever visited.

The Gusu base is not far from Yushan Town, and it is estimated that the tide is about to sweep there, and there are some people he once knew, so he can't completely ignore them, at least remind them.

When Li Ang arrived at the Gusu base, the tide was not far away, and he could already see the turbid waterline standing on the city wall, and Commander Li was directing everyone to make various preparations on the city wall.

"Commander Li, long time no see." Li Ang showed his figure and landed lightly on the city wall.

"Are you ~ Leon?" Commander Li looked at Li Ang carefully: "Where have you been in the past two years, we all thought you had ~~"

"Let's not talk about this, I came from Qinchuan City, and it has been completely flooded by the sea, and the sea water is not the most important, there are a large number of krakens in the sea, and the number is huge." Now is obviously not the time to say hello, Li Ang briefly said hello to a few people he knew, and then talked about the current situation.

"Can't hold it?" Commander Li asked in a deep voice.

"Difficult!" Leon's face was heavy.

"If we can stop the approach of the sea water, without the sea water Siren, the combat effectiveness should be reduced, not to mention that we still have a ten-meter-high city wall." Just when everyone was worried, an old man with gray hair walked up to the city wall.

The old man was wearing a white lab coat and no raincoat, but the rain was repelled half a meter away from him, and there seemed to be an invisible spherical shroud around the old man.

Li Ang looked at the old man in surprise, in his perception, the old man was not an anomaly, just an ordinary person of two levels.

"Let me introduce you, this is Professor Wang, an academician of the Chinese Academy of Sciences and an expert in astrophysics." Commander Li introduced: "This is Li Ang, our hero. ”

"Hello Mr. Li, I often hear people talk about you, the first time the base was attacked by zombies, it was Mr. Li who turned the tide." Professor Wang is a very enthusiastic person.

"Whereever, that's everyone's credit." Li Ang was a little modest: "Professor Wang, you said to stop the sea from approaching?" ”

"I think you've figured it out, I'm not a paranormal, but look at the rain."

"I was about to ask how you did it."

Professor Wang smiled proudly and took out a small black square from his coat pocket.

With his keen observation, Leon discovered that the sphere formed by the repulsion of the rain was centered on the black square in front of him.

"What is this?"

"Gravitational force I believe everyone knows that there is gravity between matter, in fact, there is also repulsion, just like the strong interaction between molecules, gravitational repulsion exists at the same time, and in the macroscopic world, because of the distance between matter, it is all gravitational force, but the repulsion force actually exists, and this thing, I call it the antimatter force field."

"Generating a material force field? What's the use. ”

"It's possible to keep all matter out, but it's a little weird, or magical." Professor Wang paused at this, and glanced at everyone with some expectation.

Li Ang couldn't help but smile slightly, this Professor Wang is also an interesting person, and immediately showed great curiosity and asked, "What does magic mean?" ”

Professor Wang was very satisfied with Li Ang's reaction, and said with a deep sigh: "As the name suggests, the antimatter force field can only repel matter, but it has no effect on living things. At this point, Professor Wang paused again.

"Aren't living things also made of matter?" A very cooperative young man spoke.

"That's right, living things are also made of matter, and I've done experiments, and antimatter force fields are also effective against biological corpses." Professor Wang continued.

"So, we can use the antimatter force field to repel the seawater, and then we'll just have to face the Kraken, right?" Leon brings the conversation back to the current predicament.

"That's right, and I've had an antimatter field generator of enough power ready when I arrived, and it can be activated as soon as it's debugged." Professor Wang looked confident.

"So what are you waiting for, start it." Commander Li said with some urgency, the sea outside the city was already close at hand.

Just as the sea was about to slap on the city wall, the krakens in the sea had already emerged, roaring, and ready to start a killing feast.

The turbid tide suddenly receded as quickly as a rewind, and was repelled to a distance of five hundred meters from the city wall, unable to advance an inch.

And the krakens who originally rode the waves fell down from the air more than twenty meters high, and all kinds of smashed to the ground, instantly falling to death and crippled a large part, as long as a few very lucky people can maintain complete combat effectiveness.

"Fire!" The soldiers on the city wall were still shocked and the sea water suddenly receded, Commander Li decisively issued the order to attack, the soldiers were very well-trained, and instinctively attacked according to the order.

Traditional thermal weapons have long been eliminated, and the guns held by the fighters are full of strong sci-fi colors, firing physical bullets, but each bullet is actually given a different effect.

Some bullets will explode violently after hitting the target, and the power is no less than the full force of the third-level ability, but the rate of fire is not very high.

And some bullets even carry corrosion, flame, freezing, electric shock and other effects, and the power is also extremely strong.

In addition to these magical firearms, there are also a large number of laser weapons, and the entire city wall shoots countless beams like hedgehogs, and a large number of krakens are killed and vaporized.

"Commander Li, we must fight quickly, the power of the antimatter force field is very large, with the current energy reserve of the base, it can only last for 12 hours at most."

When everyone was in the middle of the battle, Professor Wang told a not-so-good news.

"Is there anything to refuel?" Commander Li asked with a frown.

"Elemental crystals, the energy of the supernatural can also be used to replenish, but it is a drop in the bucket."

"Let's kill the Kraken as much as we can, we won't be able to support it for long, and they may not be able to support it for long." Commander Li comforted himself.
