"Great!"

The sudden turn of events made Yu Cheng slap his thigh with excitement.

"Brother Fenglin, you give me the recipe, and I'll have someone pack it for you right away!"

"Okay, I'll give you a ...... right when I get back."

After talking to Yu Zheng about things, Lin Feng also drove Su Xuan to find a place to live. After settling down Su Xuan, he was also ready to start refining Pei Yuan Dan and officially prepare for the battle with Shenyuan.

Although he doesn't know what the people of the God family are trying to do, he knows one thing, that is, he must win the championship of this competition, even if it is an open opponent, he must defeat it for everyone to see!

As for Su Xuan, after settling down, she was not idle, but called her old friends here, and began to collect information from the Divine Family, silently acting as Lin Feng's backing.

At four o'clock in the afternoon, Lin Feng also brought a large bag of medicinal herbs to a small kitchen of the Ning family. Now that the materials have been collected and the Dan core is already available, it is completely possible to start refining Pei Yuan Dan.

As for why alchemy in the kitchen, huh...... There's a reason for that.

Lin Feng opened an electronic cooker, stuffed everything into it one by one, and finally added water. After that, I flipped the switch and waited on the sidelines.

"What's more, modern technology is convenient. Lin Feng muttered to himself, he had also asked Ziyun about the process of refining this elixir before, but the conclusion he came to was that to refine this elixir, it would be good to use the tools in the kitchen to make soup directly.

He also heard from Ziyun that refining high-grade pills requires a different fire, but the different fire is just a flame that can produce a higher temperature. However, with modern technology, it would be a piece of cake to make something hotter than this ordinary flame.

Half an hour later, he finally fished out three pills from the furnace, and after the medicine was refined, these three pill cores were also perfectly transformed into Peiyuan Pills.

However, after refining these three pills, this matter is not over. He also had to find a place to test the effect of this Pei Yuan Dan again. So, he drove to a deserted mountain.

"Bang!"

When he reached the top of the mountain, Lin Feng also burst a huge stone as usual, consuming the true qi that had just been accumulated by the hidden vein. After doing all this, he took out a Pei Yuan Pill from the medicine bottle, and then started to swallow the heavens.

In the past, the Heaven Swallowing Gong was used to absorb other people's true qi and rebound back, but this time Lin Feng used the Heaven Swallowing Gong to absorb the spiritual energy between heaven and earth, and it did not rebound back, but turned into his own true qi. This kind of sky-swallowing skill can be said to be a veritable "sky-swallowing".

"Huh?"

After running the Heaven Devouring Gong, Lin Feng also frowned, because as soon as it was run, there seemed to be no reaction.

If in normal times, then he can also understand, after all, he uses the Heaven Swallowing Gong against the air, and expects the air to give you feedback, isn't that a fool?

However, this time he used Ziyun's improved Heaven Swallowing Skill, and there was no response, so it was really a little abnormal......

"Strange, what's the problem?" Lin Feng frowned, obviously very puzzled. His movements were strictly in accordance with what Ziyun said, but there was no reaction at all, could it be Pei Yuandan's problem?

Thinking about it carefully, the Dan Core provided by Lu Yun can only be useful to Ming Jin Martial Artists, could it be that the quality of the Dan Core is too weak......

"Whew!"

In the next moment, Lin Feng's body was abnormal again, he only felt that more than a hundred air pockets on his body were agitated at the same time, and instantly turned into an exhaust fan, directly absorbing all the aura in all directions!

"I'll go!"

The sudden change surprised Lin Feng, it turned out that the calm just now was just a precursor to the coming storm! Now he only felt that his body was frantically absorbing the spiritual energy, and these heaven and earth spiritual qi turned in the Heavenly Spirit Pill, and it was directly transformed into the Heavenly Spirit True Qi that he could compatible, and it was instantly replenished into his hidden veins. It was only ten seconds later, and the true qi in his hidden veins was instantly filled.

"That's amazing, isn't it?"

The effect of this transformed Heaven Swallowing Gong was far beyond Lin Feng's imagination. Being able to replenish True Qi in such a short period of time is equivalent to a submachine gun with unlimited firepower, and if it is a fight with True Qi of the same level, then no one will be his opponent!

Other people's true qi is limited, but the time he lasts for the drug is equivalent to infinity!

But then the question comes, how long can this Pei Yuan Dan last? If it's a minute or two, then it's a bit insufficient, after all, this Dan core is 500,000 pieces, and it will take at least five minutes before he can get his capital back.

Thinking so, Lin Feng continued to test again, but the conclusion he got was once again beyond his expectations.

Thirty minutes!

This kind of perverted effect, with the blessing of a Pei Yuan Dan, can actually last for thirty minutes!

Thirty minutes, even in a protracted battle, is more than enough. If he could start a tug-of-war with Kamihara tomorrow, he would be the winner! What's more, he still had two of these things in his hand, and he could play with them for an hour.

Even if the god is stronger than himself, after persisting for an hour, he will have to collapse directly.

But speaking of which, this is really a bit magical, just with these pill cores provided by Lu Yun, he was able to make such a good medicine. Even if you take 1.5 million to buy these medicines, you will not lose money.

Moreover, after Lu Yun improves it, he will definitely be able to make a more powerful Dan Core than this, and with a more powerful Dan Core, he will be able to refine a more powerful Peiyuan Dan.

Thinking of this, Lin Feng confirmed that investing in Lu Yun was the right thing to do.

After testing Pei Yuandan, Lin Feng also went back satisfied, eating and drinking outside with Su Xuan at night, and he didn't look like he was facing a great enemy at all.

"Brother Feng!"

When he was in the room at night, Lin Feng suddenly heard Ning Liang's worried voice, and behind him was Luo Yuan. At this time, both of them looked worried, and their voices were very nervous.

"Brother Fenglin, I heard that you are going to face the people of the Divine Sword Sect tomorrow, is this true?" As soon as he saw Lin Feng, Luo Yuan couldn't help but speak.

"You two are too ill-informed. Lin Feng suddenly couldn't cry or laugh, Tang Xiaoshuang had already told him this news before, and he still used Ning Ya's mobile phone, and Su Xuan also figured it out later. And in the afternoon, the entire ancient martial arts world was even more uproar.

And how could these two brothers know about this now?

Thinking about it, it seems that I haven't seen the two of them today. What the hell are these two doing?
