Chen Huo and the others were busy preparing related supplies, while Chen Fei found a separate room and began to experiment with the Feiyunyu spiritual core fragments in his hand.

After all, they were able to get away from the three shadow guards who were in control of the seven directions just now, mainly because of the power inspired by the fragments of the spiritual core.

Without the fragments of the spiritual core, it would be almost impossible for Chen Fei's own strength to stand alone against the monks in the seven-party control realm.

And now, the stronger masters of Qingyang City are already on their way.

We must find a way to activate the fragments of the spiritual core as soon as possible.

Fade Chen kept trying in the room, using vitality, spirit stones, spirits, and various methods to stimulate the spirit core fragments. But in the end, there was no response.

"What's going on, why can't it be stimulated now?" Fade Chen felt a little irritated for a while.

He tried his best to calm himself down, and tried hard to recall the scene when the spirit core fragments were aroused just now.

At that time, he fought against the green shadow guards of Green Wave City, and was crushed by the opponent, almost on the verge of life and death.

"At that time, my vitality, soul, martial intent, Yuan Yin, almost all the means I could use were used..."

Suddenly, Fade Chen's heart skipped a beat, as if he realized something.

"Could it be that way!"

Fade Chen immediately tried it, aroused the breath on his body, and finally injected it into the fragments of the spiritual core.

This time, the fragments of the spiritual core, which had not responded all this time, actually flashed, emitting a faint light.

"It's done!"

Fade Chen was overjoyed, feeling the breath, familiar and powerful.

"It really did."

"It turns out that stimulating the fragments of the spiritual core does not require a certain kind of fixed energy. It requires the monk to stimulate himself to the extreme, force out his full potential, and merge into the fragments of the spiritual core. Only then can it be stimulated."

After being successfully stimulated, Fade Chen began to feel the fragments of the spiritual core.

This fragment was only the size of a palm, but in Fade Chen's perception, it seemed as if he saw a bright starry sky with dots of light shining on it.

However, there is only one corner of this starry sky, and it is suddenly broken somewhere, as if a piece of paper has been torn off.

But just this corner of the starlight scattered down and shone on Fade Chen, making him feel that every inch of the pores of his body was opening accordingly, greedily absorbing the energy in the starlight.

Even, not only the body, but also the vitality in the soul and blood, is also strengthened little by little in the starlight.

"The effect of the spiritual core fragments is so strong! It can strengthen all aspects of the body."

Fade Chen couldn't help feeling emotional, but he guessed something right away.

"This fragment is a piece of Feiyunyu's spiritual core, and the so-called spiritual core is the essence core of a world. It is normal to have such an effect."

With emotion in his heart, Fade Chen tried to draw a ray of starlight into Jiujijian.

Immediately, the Jiuji Sword burst into a layer of familiar light, and it became the same as it was in the battle just now.

"It really works!"

Fade Chen raised the corner of his mouth, but soon realized something.

With the injection of starlight, Fade Chen's spirit was also being consumed violently. It took only a few breaths of time just now, and almost one-tenth of the spirit in his mind was consumed at once.

"It seems that although starlight is powerful, I can't use it at will."

"According to my current soul reserves, I'm afraid I can only pull the starlight for three minutes at most."

"Thus, my strongest combat power can only last for three minutes. Next time I encounter a strong enemy, I must fight quickly!"

Thinking of this, Fade Chen ended his experiment and took some recuperating medicines to try his best to recover the spirit that was consumed just now.

At this moment, there was a knock on the door, and Chen Huo was outside: "Boss, everything is ready."

Chen Fei got up and went out.

After giving some final instructions, Liu Yun, Chen Fei and the others bid farewell to everyone, left the second stronghold, and stepped into the mist.

Liu Yun led the way, Chen Fei and the others all wore a special cloak and followed behind Liu Yun.

This cloak has a certain protective and isolation effect, and can resist the damage caused by the fog. On the Fog City side, it is one of the necessary supplies for Fog Crow to explore Fog City.
