Chu Feng's words immediately aroused Liu Yexiang's curiosity, and she approached Chu Feng, revealing a look of eagerness to know: "Childe, is there anything strange about this 'evil spirit fire'?"

Chu Feng smiled lightly and said, "This 'evil spirit fire' has brought me inspiration. ”

"Inspiration?" Ryu Yaka blinked her wide, curious eyes.

"This 'evil spirit fire' reminds me of the fusion and use of energy, and if my idea is correct, then whatever energy I can perceive can be used by me. Chu Feng explained with a smile.

"Childe, can you really do it, that's really amazing!" Liu Yexiang looked surprised.

You must know that between heaven and earth, there are all kinds of energy, even if it is a powerful monk and a demon who dominates one side, there is also an energy that cannot be controlled.

"If the attempt is successful, and then enter the 'Demon Suppression Hu', you can use this fusion energy to fight those demon beasts. Thinking like this in his heart, Chu Feng was full of anticipation.

The last time he entered the "Demon Suppression Hu", he was just a consciousness body, and he couldn't do anything, if it weren't for the unique ability of the "Demon Demon Suppression Hu", he wouldn't even be able to subdue a lowest-level demon beast.

But now, he has finally found a breakthrough and put the fused energy into the "heart and soul space", so that he can fight as a summoner.

At this time, a small ball of "evil spirit fire" floated over, emitting a faint blue light, sometimes getting bigger, sometimes smaller, like a heartbeat, looking extremely weird.

Chu Feng stretched out his arm, and this small group of "evil spirit fire" was like a homing swallow, and it suddenly fell on Chu Feng's palm.

Liu Yexiang leaned closer, but didn't speak, probably not wanting to distract Chu Feng at the moment.

"It's interesting that such a weak energy can be fused together to last!" Just as Chu Feng was muttering to himself, the "Evil Spirit Fire" in his palm suddenly swelled several times.

After being injected with some fire elements, the evil spirit fire in front of him really grew a lot, but the experiment had just begun.

"I don't know what changes will occur after injecting 'qi'?" Chu Feng's eyes were focused, and he began to carefully inject 'qi' into this 'evil spirit fire'.

In an instant, the original pale blue flame periphery seemed to be wearing a milky white coat.

"The blend is not perfect enough. Chu Feng's brows furrowed slightly, he thought for a moment, and began to inject "Nian Energy" into the "Evil Spirit Fire" again.

The "Evil Spirit Fire" that was originally peaceful suddenly became violent during the injection of "Nian Energy", and it seemed as if it could explode at any time.

However, after a few seconds, with a bang, the "evil spirit fire" used in the experiment finally exploded, turned into countless sparks, and slowly dissipated into the air.

This kind of failure, Chu Feng didn't take it seriously at all, after all, his previous research was only achieved after experiencing countless failures.

"What's wrong, is there too much energy injection?" Chu Feng began to think about the reason for the failure just now.

In the following attempts, there were several more failures in succession, either explosions or repulsion between energies.

However, the key point of failure was still found by Chu Feng.

It turns out that in order to fuse several energies together, it is necessary to keenly control the subtle changes between energies, and it is best to inject "mental energy" first, and use it as a harmony to balance the balance between various energies.

"Childe, is this a success?" When a "evil spirit body" with scorching flames mixed with the power of thunder and lightning appeared, Liu Yexiang let out a happy voice.

"It's just that I've just mastered some tricks, and the power of this 'fusion energy' is only equivalent to a second-grade attack talisman seal, and it's far from meeting my requirements. Chu Feng said softly.

"Childe, this is a good start, isn't it?" Liu Yexiang's smile was extremely charming, she was really happy for Chu Feng.

"Next, let's see if we can integrate the 'Heavenly Energy Fire' into it!" Chu Feng started a new challenge.

Since Chu Feng experienced a Heavenly Tribulation, the "Heavenly Energy Fire" he had absorbed and mastered had also been improved, and if this fusion could be successful, then the power would at least be able to reach the destructive power of the Three-Rank Runic Seal.

Liu Yexiang suddenly turned her head to look at the side of the stone wall, and then swished through, but after breathing, she turned back again.

"Childe, there are a lot of people outside who are preparing to break in, do you need Yexiang to drive them away?" asked Liu Yexiang aloud.

"Those tomb robbers?" Chu Feng hesitated for a moment, then said, "It's good to warn them, the 'evil spirit fire' floating here alone is enough to make them have no return, not to mention that there are other existences." If they do not listen to the counsel and insist on going to die, they need no more attention. ”

"Yes, Childe!" Liu Yexiang also left once.

Chu Feng didn't want to be disturbed by the outside sounds, so he was busy arranging a layer of enchantments around him.

Outside the tomb, a group of tomb robbers were cheering for the discovery of the tomb.

"I finally found it, and it must be a big tomb. ”

"It's not in vain, brothers, take heart, and this entrance must be opened before dark. ”

"Damn, Lao Tzu has been holding back the fire all the way, and he can finally have a place to vent. ”

"Don't let your guard down, I just observed, this tomb is built on the mountain with the trend of gossip, and there must be a lot of organs inside. ”

“……”

These people are busy in front of a blurred stone statue, taking out various high-tech products from wooden boxes, with a clear division of labor, and at first glance they are a team that often cooperates.

Among them, two people were particularly special, not because of their strange appearance, but because they sat idly on the trunk of a dead tree while the others were busy.

"Fat cat, brother, I didn't lie to you, this time I'm going to open your eyes. Just now I heard my fifth uncle say that this is a big tomb, and the treasures in it can be imagined. One of them, a handsome man, reached out and patted another fat man.

Both of them are not very old.

"Plate, when are we going back, I haven't had a good night's sleep since I was tricked here by you, and I always feel the wind around me. The obese man asked.

Obviously, the two men called each other by nicknames.

"Look at your cowardice, who bragged to me that he was bold, and he didn't enter the tomb yet, so you want to go back?"

"Plate, you never told me that you would die, and there are not many evil things you have encountered these days, and I feel a chill down my back when I think of the legends about this place now. ”

"Didn't I tell you that the mist was poisonous, that's why we put gas masks. As for the dead people I saw, they should have also come here to rob the tombs, and it was obvious that they were too young to be fully prepared. ”

"Plate, legend has it that this mountain is haunted, aren't you afraid at all?"

"What's there to be afraid of, it's just a deceptive rumor!"

Just as the two were talking, a terrifying voice suddenly sounded in midair.

"Don't want to die here, leave quickly, this is not where you came!"

The voice was hoarse and low, like a yin wind blowing from a valley.
