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.

According to the protective effect, the cloak also has different grades. The higher the grade, the better the protection effect.

Of course, what Liuyun prepared for everyone is naturally the highest quality good stuff.

A group of people walked quickly in the fog. After walking for about half an hour, there was silence around them. There was nothing but the thicker and thicker fog.

There was no sound all the way, Qi Hao and the others couldn't help talking in a low voice.

"Except for the fog, there seems to be nothing special along the way."

"Yeah, the poisonous fog is blocked by the cloak, and there are no other dangers. It seems that I was too nervous before."

"This Misty City is not as dangerous as the leader Liu said!"

...

Just when the three of them were relaxing, Liu Yun suddenly called out: "Enemy attack, be careful."

"ah!"

When the three of them heard the sound, they raised their heads when they suddenly saw several black figures rushing out of the mist and pounced on their faces.

The three black shadows were moving extremely fast, coupled with the cover of the mist, when they arrived in front of the three of them, they suddenly realized that it was too late to dodge.

They could only watch helplessly as the black shadow approached, grabbing at their faces fiercely.

The three of them were almost dumbfounded.

At the critical moment, several Qi Jin shot out, hit the shadow, and fell in front of the three of them.

At the same time, Liu Yun's voice sounded: "Don't relax, be careful."

Only then did the three of them come to their senses, and quickly mobilized their vitality, relying on each other, and formed a protective formation to resist the black shadows thrown from the mist.

Next to him, Fade Chen reacted faster, almost the moment Liu Yun made a sound, he had already shot, and hit several black shadows one after another with a few slaps.

Chen Huo, Han Huai, and Yunxi were a little slower, but they cooperated with each other and tacitly blocked the black shadow's sneak attack.

Liuyun's movement was even faster, and with a few swipes, he hit more than a dozen black shadows at once.

When the situation stabilized, everyone was able to concentrate on looking at the black shadow that was hit.

They are black monsters the size of half a man, with thin downy hairs all over their bodies, membranous wings on both sides of their bodies, and sharp claws. The saliva left by the corners of their mouths drips on the ground, emitting bursts of blue smoke. .

"What is this!" Qi Hao couldn't help but exclaimed.

Liu Yun quickly explained: "This is the black shadow poisonous bat, a fierce beast that grows specially in the Misty City. It is fast, agile, and highly poisonous. Its strength is about the same as that of a fifth-level monk in the Yuantai Realm."

"It's not difficult to deal with one by one, but if there are too many of them, even monks in the control realm will get into trouble."

"There should be a nest of black shadow poisonous bats nearby. Let's leave as soon as possible and don't disturb them."

With the lesson learned just now, everyone became extremely vigilant, followed Liu Yun, and acted quickly.
