When the thunder beast entered his belly, the extremely powerful mana enveloped it and was slowly refined.

The thunder beast was unwilling to be refined and tried its best to resist.

But after all, there was a huge gap in strength between the two. With a flash of five-color divine light, all the thunder nets on the Thunder Beast's body were crushed.

The thunder beast let out a roar of extreme anger.

But all to no avail.

The five-color divine light swiped down again without mercy, and the form of the thunder beast immediately dissipated and turned into a ball of blazing white light. It was like a big sun, emitting scorching heat.

Even though the outer layer was wrapped with thick mana, Cui Chen's physical body was comparable to a spiritual treasure, and he felt a burning pain at this moment.

But Cui Chen didn't care at all at this moment, but was concentrating on the inner sight of the light group.

In his perception, this light group was clearly a ball of "qi".

It is different from the innate purple qi, but the qi of yin and yang.

The attributes of yin and yang are constantly changing, but they always maintain a balance, and the wisps of lightning are born out of thin air between the transformation of yin and yang. The white light Cui Chen saw is the aggregation of these thunder lights.

"The Qi of Yin and Yang, when thin, becomes thunder, when excited, it becomes electricity!"

Such a thought suddenly appeared in Cui Chen's mind, but as the thought came about, an illusory golden rune suddenly appeared in the sea of ​​consciousness, glowing with dazzling light.

And as the golden runes appeared, the source of the evil-fighting divine thunder condensed in his body seemed to be suddenly pulled by some kind of force, suddenly rioted, and struggled to come out of the Nascent Soul.

After Cui Chen was startled for the first time, he relaxed his Nascent Soul and allowed the golden light spots to emerge from the Nascent Soul, slowly drifting toward the golden runes in front of him and swarming into it.

As the golden light spots blended in, the golden runes slowly solidified.

At the same time, Cui Chen's thoughts about the evil-fighting divine thunder kept coming to his mind.

The evil-fighting divine thunder is known as the source of wood, containing vitality and restraining evil ways and ghosts...

At the same time, the moment Cui Chen understood the Law of Thunder, the outside world suddenly became turbulent.

Immediately afterwards, thunder shook the sky, and countless thunder lights condensed out of the dark clouds. The sound was far greater than when Cui Chen advanced to the late stage of integration, and the entire fifth layer of the abyss was shrouded in a sea of ​​thunder.

The monsters living on this level sensed the pressure of thunder, and no matter what their cultivation level, they all tightened their bodies and started to tremble.

Hongfen, Han Li, Hongyu and others immediately flew out of the cave and looked at the vast white sea of ​​thunder, all with pale faces.

I can't afford the slightest resistance.

"What's going on? How could such a strange phenomenon happen for no reason?" Hongfen asked with fear in her eyes.

"Could it be that the master is attacking the Mahayana stage?" Hongyu guessed.

"No! Although the visions of monks breaking through the union are different, they all attract the energy of heaven and earth to gather, but now there is no such thing as a swarm of energy from heaven and earth." The succubus was born in the demon world and knows quite a lot about the visions of monks breaking through the Mahayana.

Duo, after comparing the situation, immediately shook his head in denial.

"With such a movement, it can't be that a rare treasure with thunder attribute has been born!"

"Then let's look for it?"

"It's better to say goodbye. We are together. If a thunderstorm hits, we can resist together. We are not even sure we will survive alone. Huh? Why didn't your husband come out? Logically speaking, there is no way that such a movement would not alarm him.

Even if the main body doesn't come out, the clone should come out to check the situation." At this time, Hongfen finally realized that one person was missing.

"This vision may have been caused by my father-in-law's cultivation of magical powers!" Han Li said after pondering for a moment.

After hearing this, everyone looked at each other and felt that what Han Li was talking about was very possible.

In the next few days, the fifth floor was shrouded in a sea of ​​thunder, but fortunately, although these thunders were extremely powerful, there were no signs of them falling down.

This made everyone who was worried breathe a sigh of relief.

Finally, after the fifth day, the thunder suddenly dissipated, just like when it appeared, without any sign.

In the medicine garden space, Cui Chen slowly opened his eyes tiredly, but his face was extremely excited.

He raised his hand and pointed towards the void in front of him. There was a "crack" sound and a golden thunder appeared out of thin air.

Then his mind moved again, and the thunder suddenly flew out, like a ring wrapped around his finger.

It's gentle to the touch, as soft as jade, without the violence of thunder at all.

But Cui Chen could clearly sense that this chopstick-thick thunder had the terrifying power to kill ordinary monks in the integration stage with one strike.

This is the result of his not doing anything casually.

If you use all your strength to perform it, even if you use it to fight against a true Mahayana powerhouse like Qing Yuanzi, you will still be able to avoid falling behind in a short period of time.

Forcibly suppressing the joy in his heart, Cui Chen gently twisted his fingers to extinguish the golden thunder wrapped around his fingers. Then he moved his lips, transmitted a word to the outside world, and fell asleep with his head tilted.

Understanding the rules is really an extremely labor-intensive matter.

If your mind is strong enough, you might be able to comprehend more of the laws of thunder before the qi of yin and yang dissipates this time, and it is not impossible to even get a glimpse of the yin and yang avenue.

However, Cui Chen was already very satisfied with such a harvest.

During this sleep, Cui Chen slept deeply and comfortably.

Youyou didn't wake up until half a month later.

After raising his arms and stretching, Cui Chen returned to the cross-sitting posture, then turned his hands, and with a flash of inspiration, a half-foot long thunderwood appeared in his hands.

Cui Chen's eyes flashed with light as he stared at the Law of Thunder runes above, and at the same time compared them with the Law of Thunder he had comprehended.

It turns out that there is indeed some overlap between the two.

But just when Cui Chen wanted to continue his efforts and understand more laws of thunder, he found that it was still extremely difficult. He exhausted his mind several times in a row and got nothing.

This made Cui Chen quite disappointed, so he could only put away the thunder wood and continue to practice "Daoji Zhenling Jue".

Ten years passed. Cui Chen estimated that the elixir was almost ripe, so he ended his practice and wandered around the medicine garden.

After some inspection, Han Li lived up to his expectations. Not only did he cultivate the Qingluo Fruit, but he also matured a lot of the elixir for refining the Yiqi Hundian Pill.

Cui Chen immediately picked the elixirs and fruits and began to refine the elixirs.

Qing Luo Dan is just one thing, but the difficulty of refining Yi Qi Hun Tian Dan is really not low.

Even with Cui Chen's current alchemy skills, he failed several times before finding the key and successfully refining one. However, the rate of subsequent elixir formation was still frighteningly low, with seven or eight attempts of refining failing.

Fortunately, there was enough spiritual grass, so Cui Chen was able to refine a sufficient amount of elixirs.

Immediately afterwards, he took the elixir and went into retreat.

Taking Yiqi Huntian Pill and Qingluo Pill at the same time, the effect is extremely amazing, allowing Cui Chen's power to increase at a speed that other monks in the integration stage could not imagine.
