As the fire-soluble crystal magma that had been deep into the ground for thousands of meters, the rolling white magma rose up with shocking green flames. Even the hot fire waves of Yusan were enough to instantly dissolve the ordinary magic weapons and spiritual weapons in the cultivation world.

Above the rolling cyan flames, you can see a man shrouded in silver flames. His eyes were closed and the silver flames around him kept flashing to resist the terrifying cyan flames that occasionally plague around him.

After three days and three nights, the fire-soluble crystal magma never stopped its roar. The rolling magma made the surrounding hard stone walls tremble occasionally, as if someone had caused its anger that had never been seen in a century.

Faced with the roar of the fire-soluble crystal magma under his feet, Zhang Heng was unmoved. The silver flames around him were enough to deal with the attacks of a small amount of Qingyan. At this moment, he was manipulating the fire of the void with all his strength.

If someone can go deeper than 100 meters of the "fire-soluble crystal magma", he can see that there is a hollow part of the magma that is twice as big as a football, like a huge bubble.

Around this huge bubble, the surging green flames were gathering here frantically, as if there was a magical vortex here, absorbing the surrounding green flames.

In fact, this mysterious bubble is the "Void Flame" currently controlled by Zhang Heng.

Zhang Heng discovered that the deeper the bottom of the magma, the purer the flame essence it contained was. He could only barely control the "Void Flame" to enter the magma base for more than 100 meters, and he could no longer do anything.

The fire-soluble crystal magma contains the terrifying fire from the center of the earth, which itself has the effect of resisting the spiritual consciousness of the cultivator. The spiritual consciousness of the Nascent Soul stage can generally only penetrate dozens of meters deep into it, otherwise it will damage the mind and mind. Once it exceeds a certain limit, this barrier to the spiritual consciousness will increase geometrically.

The connection between Zhang Heng and the Void Flame is very special, so it can be penetrated by a hundred, which is beyond the limit that a Nascent Soul cultivator can reach.

In Zhang Heng's body, red halos that were visible to the naked eye were flowing, and they were being absorbed by Zhang Heng's body little by little.

These red halos are the flame essence contained in the fire-soluble crystal magma, and are even more dreams of cultivators who practice fire-based skills. But at this moment, they enter Zhang Heng's body like flowing water and are quickly absorbed by him.

If ordinary cultivators who practice fire-type skills are allowed to see the scene at this time, they may be jealous to the point of going crazy.

However, our client Zhang Heng, stepping on the aftermath of Qingyan, sighed: "The speed is much slower than that time to refine the 'Sky Thunder Essence'..."

The earth-center fire in the fire-soluble crystal magma is still not so pure and cannot be compared with the true earth-center fire from the heart of the earth. It is said that the true earth-center fire can dissolve most things in the world. As long as a trace flows out, countless earth-center fire caves can form.

The "Sky Thunder" that Zhang Heng devoured last time was considered a relatively high-level existence, much stronger than the thunder contained in the small heavenly tribulation. After all, those thunders were fired against Luo He's clone. Even if the level was not as high as the real thunder, it was not something that the top cultivators in the Three Star Domain could resist.

As time passed by little by little, Zhang Heng's body kept absorbing the essence of the earth fire in the "fire-soluble crystal magma". Red halos were flowing only in his body at first, and later extended to the surface of his body.

A month later, the silver flame outside Zhang Heng's body had disappeared, replaced by a dark red aperture.

When the green flames scattered around him touched Zhang Heng's body, they were like a breeze blowing, and were absorbed part of them.

Occasionally, Zhang Heng would open his mouth and spit out a mouthful of flames into the void, emitting a terrifying high temperature.

When he uses his flame magic power, his body surface will show a crystal red luster. In this case, his resistance to flame will greatly increase.

At some point, Zhang Heng opened his eyes and saw a flash of fire in his eyes, and the surrounding fire-type spiritual power trembled.

"puff!"

Two silver-red flames flashed around him, namely silver-flame and dark-fire flames, which set him off like a flame king who fell from the sky.

At the same time, his body surface showed a crystal red luster, and a red aperture was loomingly formed around him.

Huh! His body turned into a sharp sword and flew dozens of meters downwards.

Suddenly, the blue flames in the sky drowned him in it.

Zhang Heng's expression was indifferent, standing among the harsh green flames. The silver-red flames around him kept swallowing and assimilating the surrounding green flames, keeping most of the flame attacks out. The remaining flame power could not cause harm to Zhang Heng's body.

Standing in the blue flame for a while, Zhang Heng's eyes began to glance at the white fire-soluble crystal magma rolling under his feet. After thinking for a while, he said lightly:

"Although I have initially possessed the flame magic power, enough to deal with the fire attacks of the Nascent Soul level, it may be a bit reluctant to resist the 'fire-soluble crystal magma'."

At this moment, behind Qingyan, a red-haired boy appeared. He smiled and said, "Brother, in just one month, you can master the magical power of flames and absorb so many flame essences. In the future, when facing monks who are good at fire-based martial arts, you will have a great advantage."

Zhang Heng seemed to have noticed his arrival for a long time and sighed: "After absorbing so much earth fire essence, even if my cultivation has increased, I still have a considerable distance from advancement. I have to go out and go to the ten-year appointment."

Although he mastered the magical power of flame, Zhang Heng was still a little disappointed. The "Crystal Core Stage" is still a little far away from him and is destined to be difficult to break through in a short period of time.

"Brother, are you leaving here?"

Zhao Rui asked in surprise, with a reluctance on his face.

"Yes, I will leave here temporarily in another month. As for how long it will take to come back, it is difficult to determine, but after I finish the work, I will do it as soon as possible."

Zhang Heng replied with a smile.

Instead of asking Zhang Heng what he was going to do, he asked, "Does your brother need my help?"

After thinking about it for a moment, Zhang Heng felt a little moved. If Zhao Rui said one person, he would have a greater chance of success in the secret place of the "Hundred Refinings and Little Weapons Sect".

But when he thought about it, Zhao Rui also needed to take charge of Jiyan Sect. Once he left here, he might be able to take advantage of the situation by other forces in Qinghushan. What's more, according to the agreement that year, only four people participated in the ten-year agreement, and their cultivation should be in the elixir stage, so it is difficult to pose any threat to Zhang Heng.

In the end, Zhang Heng refused Zhao Rui's intention to help and sarcastically said: "I haven't seen you for a month, and the 'Drunk Immortal Soft Jade Scent' on you has been lifted. I think the relationship between you and the 'Embroidered Incense' can be further developed?"

When Zhao Rui heard this, his face turned red, but his expression dimmed again. He turned around, looked down at the hot white magma under his feet, and said in a low voice: "Brother, I have not received her treatment..."

"What? You didn't accept her!"

Zhang Heng's expression changed slightly and he said in surprise. (To be continued. If you want to know what happens next, please log in.readnovel., more chapters, support the author, and support genuine reading!)
