Everything is ready to go.

Yang Yunfan put all the medicinal materials into the Dan furnace in turn.

At the same time, in the palm of his hand, there was a trace of purple flames, and the purple flame light continued to surge, and strings of flames rose into the air. The air was so high that it burned the space a little distorted.

"Go!"

With a flick of Yang Yunfan's fingers, a purple flame of the Pure World instantly broke away from his palm and floated into the Dan furnace.

As soon as the medicinal herb was stained with the Pure World Purple Flame, it instantly made a "snort" sound, and the branches and leaves curled up in the flames, turning into charred black. However, this Pure World Purple Flame was extremely magical, although the medicinal herbs turned into black ashes, but that mass of "medicinal power" did not melt, but was scorched by the flames, turning into a cloud of white light.

Clusters of white light rose up, rolling slowly, reflecting a faint luster, and in the Dan furnace, under the burning of the Pure World Purple Flame, they began to merge with each other.

This white light was originally the size of a fist, but after it was fused, it continued to condense and become smaller, only the size of a ping-pong ball. And after reaching a certain boundary, the white light suddenly brewed a golden halo, which was extremely close to the color of the power of merit.

"It's almost time for fire!"

Yang Yunfan's eyes froze, and he picked up the inner pill of the emperor ribbon fish from the side, and crushed it with sneer.

A trace of demonic aura began to spread. When it came into contact with that golden light cluster, it was like a long whale drawing water, absorbing the demonic qi directly into the light cluster.

The golden halo, constantly flickering, illuminates the entire laboratory, which is somewhat dazzling.

When the last drop of demon qi was also swallowed by the golden light...... Suddenly, the light faded. A dripping, round, and incomparably purple golden pill was suspended in mid-air.

On the surface of this pill, there are ripples like water, rippling continuously, accompanied by its own purple-gold light, which looks simply magical.

"Tsukidan!

Yang Yunfan didn't dare to delay, and hurriedly brought a special jade bottle, this jade bottle is specially refined, and there is a locking spirit formation in it, which can lock the elixir aura and prevent it from passing.

Tsukidan carefully took the jade bottle, Yang Yunfan put it under his nose a little excitedly and sniffed it lightly, and a strange fragrance emanated from it, which made him feel refreshed.

"This Zhuji Dan is probably the best elixir I have refined so far, and it is the best in terms of appearance and aura. I hope this Tsukidan won't let me down!"

This Zhuji Dan, Yang Yunfan is only ready to refine it by himself and take it by himself. He didn't dare to tell anyone the secret that he could refine Tsukidan.

I don't know how many monks there are in the world, and most of them are stuck at the peak of the Qi Induction Realm, and it is difficult to break through to the Foundation Building Realm. It can be said that if there are no other adventures among the ten monks of the Qi Induction Realm, at most two or three can enter the Foundation Building Realm.

These two or three, in the foundation building realm, can't go far, at most in the first layer of the foundation building realm, and the second layer lingers.

"This Tsukidan, I can't take it right away. I want to adjust the inner heaven and earth, raise my body and mind to the most perfect level, and then break through!" Yang Yunfan did not take it immediately after refining the Zhuji Dan. Instead, he took a deep breath, forcibly suppressed the eagerness that was tumbling in his heart, and then adjusted his state.

Although Tsukidan has a high probability of helping the monk break through to the Tsuki-Tsuki realm, there is also a possibility of failure.

It took Yang Yunfan two months to collect all these materials. Especially the inner dan of the emperor ribbon fish, with a certain amount of luck. Let the snake feather go to the East China Sea to hunt and kill, I'm afraid that the sect in the East China Sea is on guard, and it will be difficult to catch it. Yang Yunfan didn't want to take such a needless risk.

……

Temporarily coming out of the laboratory, Yang Yunfan put down all his work and did not continue his pharmaceutical research work.

For the next three days, he didn't care about anything at all and focused on adjusting his condition. Occasionally go to the mountains and forests to climb mountains, occasionally go to the flower and bird market to see pets, occasionally go to the river to fish, and occasionally ride a bicycle around Xiangtan City......

Three days later, Yang Yunfan finally felt that his spiritual power had reached a mellow and flawless state, and the golden body merit monument was also golden and bright, and there was nothing abnormal, and he realized that the time for a breakthrough had come.

……

Back to the lab.

This is designed by Yang Yunfan, the center of the Spirit Gathering Formation, and it is the place where the mountains and rivers within a radius of thirty miles and the spiritual energy converge.

The intensity of the aura is not much worse than that of ordinary sect caves.

On the periphery, Yang Yunfan also greeted the soldiers of the reconnaissance company stationed there, saying that he would do an experiment at home today, hoping that they could help guard it for an afternoon.

The officers of the reconnaissance company immediately took it as a top priority and put the neighborhood almost under martial law.

At the same time, Yang Yunfan's subordinates, Xu Qiang, Dong Hu, and the Ukrainian boxing king Abu, as well as Snake Feather and his Dragon God, are all guarding near the villa.

In the basement, Yang Yunfan slowly exhaled a breath of turbidity and took out the jade bottle from his arms.

As soon as the lid opened, the purple-gold Tsukidan slowly flew out, suspended in mid-air, flashing with an intoxicating light.

"Today is a good day, let's break through today!"

Yang Yunfan smiled slightly and took a deep breath, the refreshing fragrance made him very comfortable.

At this moment, his spirit was relaxed, his aura was running freely, and he was fully prepared.

He opened his mouth, and Tsukidan automatically burrowed into his mouth like a small fish.

"Hiss......"

A faint sense of coldness quickly spread in Yang Yunfan's mouth, and there was a mint-like refreshing taste.

However, this cold meaning came and went quickly, and ten seconds later, this cold breath turned into a warm spiritual power, which directly drilled into Yang Yunfan's body and went straight to his dantian.

In his dantian, a purple bean sprout-like Neidan suddenly trembled.

This purple-gold inner pill is the Hongmeng spirit seed produced after cultivating the Hongmeng Purple Qi Technique, and at this time, this spirit seed, after receiving the energy of Zhuji Dan, actually absorbed it frantically.

"Huh?"

Yang Yunfan's body shook slightly, and in the laboratory, the calm air suddenly rippled.

"Whoa!"

Countless pieces of white paper began to fly.

In Yang Yunfan's body, the Hongmeng Spirit Seed frantically absorbed energy.

Soon, the Hongmeng Spirit Seed, which had just sprouted, absorbed the energy, and actually gave birth to a few tiny tentacles underneath, which took root directly in his dantian.

His dantian is like the earth, and the Hongmeng spirit seed is rooted in the dantian.

A peculiar energy, as if heaven and earth were merging, exploded in Yang Yunfan's body.

Countless pure energy, the power of the five elements, the qi of yin and yang, and the power of heaven and earth began to rampage wildly in Yang Yunfan's body.
