"What can I do?" Xuanyuan Wanyu asked.

"Use this." Li Feng took out the blue crystal.

"Is this the crystal of monsters in this space?" Qi Wei glanced at the blue crystals and said, "Li Feng, do you think these blue crystals are related to this blue crystal?"

"I only have this guess. I don't know if it is true, but I think it is very likely." Li Feng said.

"Then give it a try. Which of you has this blue crystal?" Qi Wei looked at Xuanyuan Wanyu.

"I have."

"Me too."

There is no one who has come to this space who has not killed a monster. Although not every monster killed takes a blue crystal. But everyone has a lot of blue crystals in their hands.

Li Feng turned his palm and took out several blue crystal stones.

Of course, the blue crystals Li Feng took out were not only those of the monsters Li Feng killed, but also those of Xu Qing and the others.

"Li Feng, what should we do now?"

After everyone took out the blue crystal, Qi Wei asked Li Feng.

"Shoot it over." Li Feng thought for a while and said.

"Shoot it over?"

Hearing Li Feng's words, everyone was stunned. Is this Li Feng's method? What method is this?

"Yes, shoot it." Li Feng nodded, flicked his wrist, and shot the blue crystal in his hand.

Boom boom!

When the blue crystal stone hit the blue crystal, it exploded and turned into waves of extremely terrifying energy, which was sucked and floated toward the blue crystal.

"this……"

"Is this blue crystal useful for blue crystal?"

"What the hell is going on?"

Qi Wei and others had doubts in their eyes.

When Li Feng said this method just now, they thought it was ridiculous, but now that they saw this scene, they knew it was not the case.

But how to explain the scene before us?

"Whoosh whoosh whoosh..."

However, despite their doubts, Qi Wei and others still shot the blue crystal in their hands.

When these blue crystals hit the blue crystal, they all exploded and then turned into waves of energy, which were absorbed by the blue crystal.

After absorbing the energy of dozens of blue crystals, Li Feng and others can feel the energy released by this blue crystal more clearly.

"This hasn't changed?"

"Is Li Feng's guess wrong?"

After waiting for a long time, there was no change in the blue crystal, and Qi Wei and others became a little impatient. After all, there were unknown risks in this hall, and it was impossible for them to stay here longer.

"us……"

"boom!"

Just when Li Feng was about to say something, the blue crystal in front of him suddenly shook.

Immediately afterwards, wave after wave of energy fluctuations swept away in all directions.

However, unlike the previous energy fluctuations, the energy fluctuations swept out this time were very stable. It had no impact on Li Feng and others.

Li Feng and others looked at each other and saw the excitement between them.

Because this means that the blue crystal has changed.

Whoosh!

At this moment, the blue crystal started to rotate on its own.

"Look, what is that?"

"That's..."

Li Feng and others looked shocked, because at this moment, lines appeared on the blue crystal.

"What kind of technique do these lines seem to be?"

"No, these are not exercises, they are martial arts."

"That's not right either."

Qi Wei, Xuanyuan Wanyu, Yu Zheng and others looked at the lines on the blue crystal in shock.

But at this moment, Li Feng and Haishan's expressions turned very ugly.

Because at the moment when the lines on the blue crystal appeared, the black dragon restriction in their bodies emerged from the depths of their bodies.

And after the black dragon restriction emerged, it crazily devoured their vitality.

"Is this what the black dragon does?"

Li Feng simply sat down cross-legged and then entered his consciousness deep into his body.

Under Li Feng's observation, he found that the Black Dragon Restriction in his body was like a monster, devouring his life force crazily. At this moment, Li Feng clearly sensed that the Black Dragon Restriction was growing rapidly after devouring his life force.

Almost instantly, the black dragon's restriction increased several times.

"What exactly is this black dragon restriction?"

"Why is that so?"

Li Feng tried his best but could not solve this problem.

Li Feng didn't know what the situation on the coast was like now, but it was obvious that the situation on the coast might not be very good either.

what to do?

Could he just watch helplessly as the Black Dragon Restriction continued to devour his life?

But according to the speed of devouring life, I'm afraid it won't be long before all the life in his body is swallowed up.

"By the way, blue energy..."

At this moment, Li Feng thought of the blue energy in this space.

When he tried before, the blue energy seemed to have no effect on the black dragon restraint, but the blue energy was able to force the black dragon restraint from the depths of his body, which also meant that the blue energy was not useless.

Now he has no other choice, so he can only try this method.

At the moment, Li Feng ran the Zhenxing Jue to absorb blue energy.

In this space, there is a lot of blue energy, and on this island, blue energy is extremely abundant, and it is the same in this hall. Therefore, Li Feng is not worried that no blue energy will be absorbed by him.

absorb.

As the Zhenxing Jue operates, waves of blue energy are absorbed.

Li Feng knew very well how terrifying this blue energy was, so when the blue energy was absorbed, he used his true energy to force him towards the Black Dragon Restriction.

boom!

After the blue energy and the black dragon restraint collided, Li Feng felt severe pain from the depths of his soul.

This severe pain made Li Feng feel that at this moment, the world was silent for it.

I don't know how long it took before Li Feng regained his feeling.

"This pain is simply unbearable. I..."

Thinking of this, I suddenly discovered that at this moment, the black dragon restraint in the body was devouring life at a much slower rate.

this……

Could this blue energy be useful?

Li Feng was shocked and confused.

If the collision between the blue energy and the black dragon restraint hadn't been too painful, Li Feng would have given it another try without even thinking about it.

But the intense pain made his scalp numb and he didn't dare to try again.

However, after thinking for a long time, Li Feng's desire to survive took over.

Li Feng knew that if the black dragon restriction was not resolved, he would definitely die. Using this blue energy to hit the black dragon restriction would cause severe pain, but at least there would be a glimmer of hope.

Thinking of this, Li Feng did not hesitate and once again forced the blue energy towards the Black Dragon Restriction.

boom!

Intense pain came, and Li Feng lost consciousness again.

After waiting for an unknown amount of time, Li Feng recovered.

However, Li Feng did not give up at this time, and once again used his true energy to push the blue energy towards the Black Dragon Restriction.
