In the secret room.

Lin Hao closed his eyes slightly and sat upright.

If someone was standing nearby at this moment, they would be able to clearly see two vortexes of air currents surging on his body.

One black, one white.

Under the coordination of the spiritual talisman seal, the Yin evil energy and the Yang Gang force are both in an extremely balanced state, filling Lin Hao's body.

If it weren't for the help of the talisman, his body would have exploded into pieces in the surge of yin and yang energy.

Time passes by every second.

Every cell in Lin Hao's body, every meridian, blood vessel, and bone, was like dry land that had been dry for a long time, greedily absorbing the yin and yang forces that were pouring into his body!

The degree of tempering of his body has reached a level that is difficult to achieve at the same level.

This method of absorption can be said to be the purest and simplest without any risk.

However, this Yin and Yang energy was too huge, and Lin Hao's body was beginning to be unable to accommodate it as he was madly absorbing it.

If he continued to absorb it, all the cells in his body would probably explode because he couldn't bear it.

In that situation, the outcome would be nothing more than explosion and casualties.

Although it replenishes energy, you should also do it within your ability.

Immediately, Lin Hao decisively stopped tempering and directly mobilized the yin and yang energies flowing in various parts of the body, gathering them all in the dantian, preparing to impact the ninth spiritual vein!

Boom boom!!

The surging black and white torrent surged in the Dantian acupoint like a tsunami, and bursts of rumbling sounds could be heard faintly.

Immersed in this yin and yang energy, the flame spirit infant seemed extremely excited, absorbing it madly and continuously.

Its absorption level is much greater than the energy required to temper the body!

"Haven't you had enough yet?!"

Lin Hao was slightly surprised when he noticed that the Flame Spirit Infant had no stopping trend.

If it is allowed to continue absorbing, once the energy is exhausted.

Then this time, it will be a waste of time.

Immediately, Lin Hao's mind moved, and he suddenly mobilized most of the yin and yang power.

The energy roared, and under Lin Hao's control, it quickly formed a sharp spiral, rushing towards the ninth spiritual vein around the Dantian acupoint.

This yin and yang energy originally came from a martial arts master at the third level of the Holy Domain. It would undoubtedly be easy for him to break through the shackles of a mere spiritual vein.

"Bang!"

There was almost no suspense. The spiritual vein barrier was like a piece of thin paper and was penetrated in an instant.

Nine spiritual veins are completely connected!

boom--!

Suddenly, the spiritual energy of heaven and earth in the secret room began to become restless, and continuously flowed into Lin Hao's body.

Lin Hao's aura also suddenly soared under the cleansing of the spiritual energy of heaven and earth, and was promoted to the level of a ninth-level warrior.

In this regard, Lin Hao did not stop. While using the Yin and Yang energy to consolidate his cultivation, he continued to absorb it madly to temper his body!

Because, when one's cultivation level is raised to the ninth-level warrior, the strength of the body is undoubtedly enhanced several times compared to before, and can accommodate the tempering of more energy.

Lin Hao's ambition does not stop there. He wants to take this opportunity to improve his cultivation again!

The early stage of level nine!

Intermediate!

Late stage!

peak!

In this way, Lin Hao's cultivation level soared like a hot knife through butter.

Finally, this momentum finally stagnated and stabilized at the peak of level nine!

Lin Hao opened his eyes, and a sharp gleam of light flashed across his eyes.

This retreat lasted a full four days.

"The energy of the Holy Land is indeed powerful!"

Lin Hao clenched his fists, feeling the powerful spiritual power in his body surge several times, and was secretly surprised.

Immediately, after Lin Hao adjusted his mood slightly, he took out a red stone from the storage ring.

This piece of red stone is exactly the fire source stone given to him by Ying Yuanzi.

A mysterious stone from ancient times, containing the fundamental laws of fire, is priceless!

Lin Hao stared intently, staring at the intricate flame marks on the stone.

At first, I didn't feel any changes.

But as his mind focused and he thought about the direction of the patterns, Lin Hao's entire consciousness gradually became immersed in it and he couldn't extricate himself.

The mysterious fire patterns were reflected in the mind like totems.

The rules of that pattern seemed to be evolving the origin of fire at the beginning of the formation of heaven and earth!

However, the longer he observed, the more dizzy Lin Hao felt.

That feeling is like learning the "mystery" of mathematics when I was a student in my previous life, which was obscure and difficult to understand.

Lin Hao shook his head and quickly shifted his gaze, no longer continuing to comprehend.

"The realm of law is indeed not that simple."

Lin Hao sighed secretly, then took a deep breath, allowing his chaotic consciousness to gradually return to calm.

"System, can you scan this Fire Source Stone?"

As if he felt that comprehending the laws was a bit boring, Lin Hao's mind moved slightly and he tried to ask.

"Ding, checking the fire source stone obtained by the host, which contains the mysteries of martial arts laws. You can start the system scan."

Soon, the system prompt sounded.

Upon hearing this, Lin Hao felt his heart surge.

"Host, would you like to start the system scan?"

"yes."

Lin Hao recited silently without hesitation.

In an instant, Lin Hao's pupils shrank slightly.

His retina suddenly emitted a red light like a scanner.

Under the coverage of the red light, Lin Hao used the fire source stone in his hand to scan everything inside.

"Ding, scan successful!"

After a few moments of silence, the system's voice sounded again.

In front of Lin Hao, a completely red crystal had already appeared.

It is covered with dense and fine lines, which are almost exactly the same as the flame marks on the fire source stone.

These lines look like masterpieces of heaven and earth, magical and natural, with a faint hint of the burning energy of the origin of the great way.

Seeing this, Lin Hao's eyes flashed, and the heat in his eyes became even hotter.

"Congratulations to the host for obtaining a crystal of the Law of Fire. Would you like to fuse it?"

"yes."

Lin Hao immediately acquiesced.

However, at this moment, the system's voice sounded again.

"This system scan requires '100,000 Lingyang Stones'. The host does not have enough money in their account. Unfortunately, the scan cannot be performed."

One hundred thousand?!

Lin Hao's heart skipped a beat.

Obviously, they did not expect that the consumption this time would be so great.

This amount is equivalent to being able to allow the Mantis King to evolve to the SS level!

From this we can see that the more valuable something is, the higher the cost will be.

Lin Hao immediately counted the number of Lingyang Stones in the storage ring, which was approximately more than ten thousand.

It’s a long way from one hundred thousand!

However, now the law crystal has been formed and there is no progress or regression.

"Law crystal, if the host does not choose to merge within ten minutes, it will disappear on its own. Please make a decision as soon as possible."

"Begin the countdown..."

The system totally ignored Lin Hao's embarrassment at the moment, and the cold electronic synthesized sound went straight into the countdown.
