Following the guards out of the heavily guarded building, Yu Qing called Erica.

"Hello Erica, I have finished comprehending the Yaosheng Stone, and for the next period of time, I plan to retreat and digest what I have learned. Yu Qing said into the communicator.

In the communicator, Erica's gentle voice came: "Okay, Yu Qing, if there is anything you need help with, remember to tell me." ”

"Okay, if there's anything I need help with, I'll definitely come to you. ”

Hanging up the communicator, Yu Qing walked to his small attic.

Caesar was guarding the house in the attic, a little unscrupulous, probably because he was too bored.

Yu Qing didn't bother with it, since refining the Ten Thousand Beasts Tower, it was much easier for Yu Qing to go out, and if he wanted to go to a place that was inconvenient for Caesar and a few of his spirit pets to go in the future, he just had to collect them in the Ten Thousand Beasts Tower.

Especially the huge little red.

With the Tower of Ten Thousand Beasts, it can also be easily carried.

Back in the attic, Yu Qing came to his private alchemy room.

Start sitting down and meditating.

I sat all day, and I fell into a state of enchantment, and my mind was full of thoughts, and the knowledge and skills of the medicine and elixir that I had eaten through the decomposition system were rapidly being integrated.

Coupled with the knowledge he had gained in the Yaosheng Stone, Yu Qing was fusing all the medicinal Dao foundations he had mastered so far.

Time passes slowly.

A day later, when the sky was bright, Yu Qing suddenly opened his eyes. He didn't sleep for a day, but he didn't show any tiredness at all, but was more energetic, and his eyes were full of essence.

"If nothing goes wrong, this is what the formula of Fadan and Huiling Pill looks like!"

Yu Qing's eyes were firm, and on this day, in addition to integrating the knowledge he had already learned, he was constantly constructing the idea of two prescriptions in his mind.

It's like a huge and sophisticated computer, doing rigorous work.

With the continuous increase of Yuqing's pharmacological background, the thoughts of the two prescriptions have also become clear.

"It shouldn't be a problem. In his mind, Yu Qing thought carefully about the two pills and decided to start refining the pills.

"Fadan's refining is dangerous, do you want to go to the advanced refining room of Eldis University to refine?" Yu Qing thought for a while, and felt that it was better not to go.

That place may not be safe, at least when it explodes, it is not as good as your own small building to escape.

And...... Yu Qing was confident that he would refine Fa Dan this time.

"The last time I refined to the end, the reason why I couldn't react steadily and couldn't condense the pill was because there was a problem with the ice spirit crystal, and before refining, the ice spirit crystal needed to be processed in advance. ”

"It's best to use sea quicksand, which can enhance the endurance of the ice spirit crystal without destroying the medicinal properties of the ice spirit crystal. ”

Yu Qing began refining Fa Dan.

Deal with the Ice Spirit Crystal first.

The sea quicksand is ground into powder, and then fused into the Ice Spirit Crystal, which then reacts with the Netherworld Qi......

"The development of the Federation's Dan furnace is not comprehensive, in ancient times, most of those ancient qi refiners used extremely high temperature earth fire to conduct alchemy, and a Dan furnace is bigger than a house...... Now the Dan furnace of the Federation is a little too petty. ”

Yu Qing carefully watched the reaction in the Dan furnace.

Three minutes later.

"There was no explosion, apparently it was a success. The corners of Yu Qing's mouth grinned, and after the temperature of the Dan furnace had cooled, he opened the lid of the furnace and took out three black pills the size of a dragon's eye from inside.

"The Fa Dan has been successfully refined, do you want to test the power?" Yu Qing thought for a while, and then shook his head decisively, the power of this Fa Dan does not need to be tested at all, the last time the alchemy room exploded, it was just a half-finished product, and the power of the finished Fa Dan was even twice as great as the last time.

"Gotta give it a name. Yu Qingxin said, he couldn't call the Dharma Dan, "Since it is refined with Netherworld Qi as the main material, and it is a black pill, it is better to call it 'Black Evil Pill'." ”

"Black Elixir...... It's stupid...... Whoever wants to give it a try is stupid. ”

Receiving the three black evil pills that had been refined into the space ring, Yu Qing decided that if he had a chance in the future, he must refine more, at least bring one thousand eight hundred on his body, and even if he encounters a martial artist of the God of War Realm in the future, he will throw it out in one go, and he will not die and let him take off a layer of skin.

After refining the Black Evil Pill, Yu Qing began to refine the Hui Yuan Pill.

Hui Yuan Dan's thinking is relatively mature, unlike the Black Evil Pill that needs to be established from scratch, after all, there are already two transitional immature works as a foundation, so it is much easier to establish a new prescription.

"The materials for refining the Hui Yuan Pill are more cherished than the Black Evil Pill, and in addition to the Enlightenment Tea, there are also three main medicines at the level of Heaven and Earth Treasure. ”

Of course, this is the case of excluding the Netherworld, and the Netherworld is currently only available to Yu Qing himself, and if it is cherished, it is naturally the highest Netherworld.

However, the refining of Fadan does not use too high-grade elixirs, Fadan is only an extension of the weapon, and it does not require much medicinal effect, so naturally it cannot use rare medicinal materials.

"If my thinking can be successful, the effect of the final version of the Spirit Pill will definitely be extremely strong, and it will be able to fill the aura in the body of the God of War Realm in an instant. Just like those big red pills in online games, this means that if used properly, it can make the God of War realm powerhouse save the day in battle and instantly have peak strength. ”

"The battle rhythm of the God of War Realm powerhouse is too fast, and the battle is changing rapidly, which is quite ...... Give the God of War Realm powerhouse one more life!"

Yu Qing's eyes became calm, he was extremely serious, and began to refine the Hui Yuan Dan.

The specific prescription and refining process had been conceived and prepared, and he began to refine it in an orderly manner according to his own ideas.

Half an hour later, Yu Qing stopped, put all the medicinal materials into the Dan furnace according to the steps, and began to use spiritual power to fuse the medicinal power.

Three minutes later, the medicinal liquid in the Dan furnace began to condense Dan.

"It worked. Yu Qing breathed a sigh of relief, turned off the Dan furnace, and then waited for the temperature of the Dan to drop down.

"The Black Evil Pill and the Huiling Pill are both top-grade pills, do you want to go to the Federation now to report the new top-grade pills?"

Yu Qing pondered in his heart.

The material of the Black Evil Pill is the Netherworld Evil Qi, this material cannot be exposed, and the Black Evil Pill is its own hole card, since it is a hole card, the deeper it is naturally hidden, the better, and the unexpected effect is the best.

As for the elixir.

The attraction of this elixir to the strong people of the God of War is too great, although Yu Qing has the Black Evil Pill, but this is something outside the body after all, before his own strength is not strong enough to fight against the strong people of the God Realm, the Hui Ling Pill should not be displayed for the time being.

Otherwise it will be troublesome.

Thinking of this, Yu Qing Yu Qing laughed.

It's a good thing that you're getting stronger.

At this time, Yu Qing's communicator rang, and it was a message from Zheng Lao.

"Invite me to the discussion meeting tonight?" Yu Qing turned on the communicator, looked at the message sent by Zheng Lao, and touched his chin.
