When Han Feng had eaten more than 30 strains of more than ten grades of medicine, he finally balanced, he no longer felt hungry, and the spirit refining vajra technique gradually stopped, no longer functioning, and his body was calm.

Han Feng let out a long breath and survived the catastrophe without danger, otherwise he would really collapse.

He returned to the secret room in the middle and looked at the book, but he didn't dare to practice anymore, and he didn't know where to go for a while.

"Can you still get out?" Han Feng looked up, his soul power dispersed, and he saw it at a glance, but he didn't find that there were any mechanisms in this secret room, and the stone walls on all sides were all smooth, emitting a glowing white light, making the entire secret room as bright as day.

He walked out of here, and walked around the other two secret rooms again, without any surprises.

Next, he walked into the medicine garden, walked around carefully, and finally groped around the edge, and there was nothing but two towering walls.

Han Feng sighed secretly, walked out of this medicine garden, walked through the gate, returned to the big room full of stone pillars, and searched around, and after a long time of incense, he also found nothing.

"It's really strange, since you brought me in, you can't lock me up for the rest of your life, right?" Han Feng was puzzled, he really didn't have a choice.

He turned back to the medicine garden and simply picked a lot of those elixirs, although there were almost no big medicines, and even the eighth-grade elixirs were overstretched, but there were still many elixirs below the seventh-grade ones.

He swept away these elixirs, and then went to the alchemy room to open the furnace to refine the medicines.

Since there is no way to go out, it is better to take this opportunity to improve the ability to refine the pill, and it is idle anyway. What's more, he didn't have enough resources, and he couldn't cultivate now, otherwise he would repeat the mistakes of the past and fall into the predicament of extreme hunger.

His technique was extremely skillful, refining the elixir one by one, although there were very few eight-rank pills, but the seven-grade pills still came out, and he quickly accumulated dozens of them.

In the outside world, any seven-rank pill was worth nearly 100,000 spirit stones, and his wealth was swelling dramatically.

Of course, the premise is that he can leave this cave safely.

What's more, after refining for five or six days, he finally succeeded in refining a seven-rank pill with a double pattern, he tried it, and the effect of the medicine directly doubled by nearly ten times, which was comparable to several eight-rank pills.

This is a qualitative change!

Han Feng was a little excited, and his efforts finally paid off.

He felt that he should be able to go further, so he began to immerse himself in it, and he really selflessly refined the elixir.

After the spiritual materials of the Seven Rank Pills were consumed, two or three hundred azure Miao Mu Dan were left, and his alchemy skills were basically stable at the Erhua realm.

However, no matter how he changed his refining method, he was still unable to break through to the realm of the Three Flowers for a long time, and it seemed that it was a big threshold.

Although Han Feng is a halfway monk and has not been systematically trained, as a nine-grade talisman master, he has achieved so well in the alchemy industry under the bypass of the class, and it is not enough to describe his progress by leaps and bounds. Moreover, many times he was not restricted by some rules and regulations, he dared to try a lot of alternative methods in the process of refining the elixir, which made him improve extremely rapidly, if outsiders knew, he would definitely be shocked by a large piece of his jaw, after all, in the field of alchemy, many techniques are inherited, and generally few people dare to change it without authorization, it is easy to destroy the elixir, and a furnace of precious spiritual materials will also be completely destroyed, and the gains outweigh the losses.

But Rao is like this, he has almost stopped at the realm of two flowers, and he can no longer be opportunistic, what he needs at this time is a clumsy force.

Han Feng was not discouraged, let alone gave up, he stopped for a while, waved his hand to collect those pills, and then walked out of the alchemy room and returned to the secret room where the Fu Dan Lotus Method was placed.

He took it off the table and flipped through it again, trying to see something new in it.

To be honest, this alchemy method has long been memorized by him, but he still has a lot of incomprehension, and he feels that there are countless places worth exploring.

He pondered it repeatedly, deduced it carefully, and it took a long time before he left this secret room and returned to the alchemy room again.

With a wave of his hand, Han Feng took out a large number of spiritual materials and began to refine the six-rank pill Chiri Dan.

This round came down, day and night, and he didn't know the passage of time.

In the blink of an eye, more than a month has passed, Han Feng is still staying in the alchemy room, constantly experimenting with various techniques, and various abnormal noises sounded in the Dan furnace from time to time, but under his mysterious control, there has not been a single waste pill, even if it is just a flowerless pill, it can be formed, and it also contains pure medicinal power.

He tried continuously and studied hard, but he couldn't reach the realm of three flowers, and the best of each Chiri Pill was only the level of two flowers.

And there were already nearly a thousand Chiri Pills piled up beside him, like a small mountain, the red light was shining brightly, and it was extremely dazzling.

During this period, he also repeatedly went to another secret room to watch the Fu Dan Lotus Method, sometimes looking at it for several days, which could indeed give him a lot of inspiration, and returned to the alchemy room to practice, confirming what he thought.

Although he hadn't succeeded yet, he faintly felt that the book of Fu Danhua Lotus Law was the most treasured, and there might be other secrets.

Han Feng didn't know, so he could only rely on this kind of strength to survive.

When all the spiritual materials of the six-rank pill were exhausted, he began to refine the five-grade pill, which was only used to improve his technique anyway, and he didn't care what grade of pill it was.

Time flies, and nearly three months have passed.

One day, Han Feng finally let out a long laugh of joy, just because he had finally refined a Bixia Pill with three lotus flowers on the surface, the fragrance was incomparably rich, and the gorgeous brilliance permeated the entire secret room, which was extremely beautiful.

His soul power dispersed, and he was about to pull this Bixia Pill out of the oven and fall into his hands.

At this time, dense lines suddenly appeared on the four walls of the secret room, and the white light shone brightly, condensing into flowers, and the flowers fluttered down one by one, filling the room with fragrance.

It was almost as if he was celebrating something, as if he was congratulating Han Feng on his success in refining the Three Flowers Pill.

This phenomenon was too sudden, making Han Feng stunned on the spot, and he didn't react for a while.

At this moment, the white light in the sky quickly converged above the Dan furnace, and after a while, it turned into a light and shadow, like a woman, but her appearance was blurry, and she couldn't see what it looked like at all, as if she was covered with a veil of mystery.

Han Feng was shocked, and just as he was about to make a move, this light and shadow stretched out his slender jade hand, and with a slight click, the mysterious power immediately descended, firmly binding Han Feng.

"What's the matter? Aren't you congratulating me? If you perform well, you'll suffer?" Han Feng was shocked, but no matter how he struggled, the combined use of crystal soul power and dragon descending power would not help, he had to wait and see what happened.
