"Run!"

Although Li Chen didn't know what kind of shell it was, the shells developed after the cataclysm were extremely powerful, not to mention that this kind of huge cannonball was still fired by a very fast source energy fighter.

"Meow!"

Xiao Hei quickly grew bigger, Li Chen grabbed Li Xi, landed on Xiao Hei's back, and quickly fled into the distance.

While fleeing, Li Chen did not forget to look back at the source energy fighter in the sky, only to see that the source energy fighter, after firing the cannonball, two fiery red streamers appeared in the tail, and in the blink of an eye, it disappeared.

The source energy fighter also escaped?

After firing a shell, the source energy fighter escaped? The speed of the escape is faster than itself?

This strange scene made Li Chen's heart surge with a strong sense of unease, he stared at the rapidly falling cannonball, and after a while, Li Chen suddenly exclaimed: "That's the source energy nuclear bomb being developed!"

The nuclear bomb is the most powerful weapon before the cataclysm, a nuclear bomb can extinguish the vitality of a city, it is called a forbidden object, and it is rarely used, although before the cataclysm, many countries have it.

After the cataclysm, in order to fight against the overwhelming beasts, the human high-level launched a lot of nuclear bombs, although the lethality of those low-level bear search nuclear bombs is huge, but for those high-level fierce beasts, the power of nuclear bombs is not as strong as imagined.

Therefore, after the cataclysm, the Federation began to study the fusion of source energy and nuclear energy, and wanted to develop a source energy nucleus to use to deal with fierce beasts.

Source energy is a very magical power, which can turn decay into magic, if you can fuse the magical source energy with the terrifying nuclear energy, then the developed source energy nuclear bomb will be incredibly powerful.

It's just that this source energy nuclear bomb is just a proposition, and it is under development, Li Chen has only read some records, and he has not heard that the Federation has developed a source energy nuclear bomb.

However, the current situation made Li Chen have to think about where to go, because if that shell was really a source energy nuclear bomb, it would be useless to escape.

Although Li Xi didn't know what a source energy nuclear bomb was, she knew what a nuclear bomb was, before the cataclysm, a small island country on the edge of Huaxia had invaded Huaxia, and at a critical moment, the strongest scientific and technological power before the cataclysm, Mi Guo, dropped the two atomic bombs that had just been developed on the island country, so that the two cities of the island country were instantly turned into ashes, and there was no way to recover for decades.

And the source energy nuclear bomb, just listen to the name, you know, the power is definitely not comparable to ordinary nuclear bombs.

"Boom!"

The cannonball finally exploded, and a huge mushroom cloud began to spread at an incredible speed, although Xiao Hei's speed had reached its limit, but it was obviously not as good as the spread of the black smoke.

The strong flash of light made Li Chen's eyes fall into darkness all of a sudden, and the white source energy was frantically infused, allowing Li Chen to regain his vision after a few seconds.

When Li Chen saw the situation in front of him clearly, the hairs on his body stood up!

Anything touched by that force, whether it was a building or a beast, was reduced to ashes in an instant, and nothing could resist it.

Li Xi was also stupid, the speed at which the smoke spread was incredibly fast, not to mention that Xiao Hei had now been sealed with source energy, even if he hadn't been sealed, he wouldn't be able to escape!

"Into the earth!"

Li Xi went berserk, his body quickly turned into a zombie form, and the earthy yellow source energy turned into a huge light shield, enveloping Li Chen and Xiao Hei in it.

Under Li Chen's stunned gaze, Xiao Hei plunged into the earth, as if on the ground, advancing without any hindrance.

What kind of fierce beast is this young lady of his own? Li Chen's head is in chaos, so far, he has found two kinds of source energy in Li Xi's body, one is the fire attribute and the other is the current earth attribute.

Could it be that our family's genetics are very strong? Why do you and your sister have two kinds of source energy? Li Chen thought nonsense in his heart, but his ears heard Xiao Hei's frightened cry.

Xiao Hei was a fifth-order fierce beast, and he had already possessed divine thoughts, and it seemed to sense some danger, and let out a cry that Li Chen had never heard before.

Don't...... Isn't the earth able to stop the invasion of the source energy nuclear bomb?

Li Chen quickly diffused his source energy, and in the underground, his source energy diffusion was greatly limited, but this time Li Chen only presented a line of source energy to the ground, so the consumption was not large, and the distance was far enough.

"Poof......

A mouthful of blood spurted out, and Li Chen's source energy touched an incredibly destructive force, which actually invaded his body through his source energy!

His head was dizzy for a while, and Bai Yuanneng frantically pounced on the trace of strange power that had invaded his body, but it was difficult to stop.

No, the white source can't bear it!

Li Chen quickly replaced it with black source energy, but in the face of that trace of power, the speed of devouring was not satisfactory, and that trace of power in Li Chen's body spread extremely fast, and the devouring of black source energy could not catch up at all!

Moreover, the moment Li Chen's source energy touched that trace of power, he also discovered a fact that made him desperate, that is, the earth could not stop the invasion of that force, and the speed of erosion by that force far exceeded that of Xiao Hei!

The situation in his body was already extremely bad, Li Chen felt that his body was about to lose control, and he couldn't help but be secretly anxious, and yelled at Li Xi and Xiao Hei: "Sister, Xiao Hei, you can't resist the power of suction!"

Although they didn't understand what Li Chen wanted to do, Li Xi and Xiao Hei both chose to believe Li Chen, and while feeling a suction force, Li Xi and Xiao Hei did not resist.

As soon as it was dark, Li Xi and Xiao Hei found themselves in a narrow space, and Li Chen, who was covered in blood, had already fainted on the ground, and he didn't know what to do.

"Brother, Li Chen!" After Li Xi came to his senses, he rushed to Li Chen's side and shook Li Chen's body vigorously.

Li Chen didn't react at all, in fact, when that trace of strange and tyrannical power entered his body, his source sea was already facing collapse, if it weren't for his black source energy to stop the invasion of that trace of power, Li Chen wouldn't even have time to take Li Xi and Xiao Hei into the space in his body.

And after entering the internal space, in Li Chen's body, three forces were entangled together, making Li Chen's source sea chaotic, especially the external force was too tyrannical, and Li Chen couldn't bear it at all.

"You are the only seedling of my Li family, brother, you can't be fine!" Li Xi cried, Li Chen is her only relative, if even Li Chen is dead, then she is really alone.

Xiao Hei also came to Li Chen's side, stretched out his tongue, and licked Li Chen's face one by one, but Li Chen completely lost consciousness and did not react at all.

Li Chen, who lost consciousness, didn't know that in his body, three forces were fighting wildly, although the white source energy and the black source energy came from the same source, they were opposed to each other, and the power of the source energy nuclear bomb was not right with the two forces, and he wanted to destroy the two source energy.

The two source energies are like generating consciousness, fighting against that trace of power, but that trace of power is too powerful and powerful, and the two source energies are not opponents at all.

Li Chen's body began to crack slowly, and blood continued to flow out of the cobweb-like scars, staining Li Chen into a bloody man.

"What's going on? What's going on?" Li Xi was completely panicked, she was only four years old, she suffered a cataclysm, and after waking up, she became a zombie, although in the end Li Tianguo found her, gave her a safe place to live, and also told her a lot of outside knowledge and situation, but Li Chen's current situation, I am afraid that Li Tianguo has no choice, how could Li Xi know what to do?

However, when she saw that Li Chen's body began to crack, a trace of determination appeared on her delicate little face.

She sat cross-legged beside Li Chen, stretched out her sharp fangs, and two drops of colorful blood emerged from her two fangs.
