After returning to the villa, Lu Chen started preparing immediately.

The three best elixirs have finally been collected, and the other auxiliary medicinal materials have been prepared long ago.

Next, the most critical step is to refine the marrow cleaning pill.

"Wang Xuan, I'm going to be in seclusion for a day. Please keep your guard and don't let anyone come in and disturb me." Lu Chen reminded.

"Don't worry, Brother Chen, even if the Heavenly King comes, I can't enter this door!" Wang Xuan patted his chest and promised.

Lu Chen nodded, looked at Liu Gongquan again, and said, "Doctor Liu, Uncle Xie will leave it to you for care. Before I leave the seclusion, there will be no accidents."

"Leave it to me. Although I can't cure Xie Bengong's illness, it's still fine to prosper his life for a while." Liu Gongquan said.

"Okay, then please both of you."

Without saying much, Lu Chen walked into the temporary renovated alchemy room alone after giving a few words.

The medicinal materials have been collected, and the alchemy furnace, charcoal fire and all kinds of materials are fully prepared.

However, Lu Chen was not in a hurry, but meditated for a long time.

Only when he was relaxed and calmed down did he start to practice alchemy.

The marrow-cleaning pill is crucial and determines whether Xie Sinian can survive.

As a top-grade elixir, its difficulty in refining is comparable to that of previous life-extending pills, but due to different types, there are great differences in details.

Lu Chen had simulated it hundreds of times in his mind, and all the steps were clearly clear.

As long as there is no mistake in practice, there should be no problem.

First, install the furnace, then place the cauldron, grind, burn sand, and solidify the mud. Next, control the furnace temperature, refine and fuse.

Each step is very important and there are no mistakes.

Lu Chen took steady steps and began to devote himself to it.

Time is passing by little by little.

Lu Chen was calm and accurately controlled the temperature of the fire, sometimes violently but gentle.

The spiritual medicines in the alchemy furnace are constantly refining, fusion, refining, and fusion.

That's it, I don't know how long it has passed.

The elixir turns from solid to gas, then from gas to liquid, and finally converts into solid.

After repeating this several times, we finally reached the final critical step, Condensing the Pill.

Lu Chen took a deep breath and began to activate Xuanqing's qi, which was infused into the alchemy furnace bit by bit.

The elixir needs to be guided by true qi, which not only increases the success rate, but also becomes very good after the finished product.

"Hosh, hush, hush..."

The fire under the alchemy furnace became more and more prosperous, and the Xuanqing qi infused by Lu Chen also became more and more.

Gradually, his forehead began to sweat and his body was covered in white mist.

It lasted about a stick of incense, and Lu Chen suddenly took action and slapped his palm on the alchemy furnace.

"Bang!"

A loud bang.

The lid of the elixir bounced open directly, and a strong fragrance of medicine immediately gushed out.

Lu Chen looked closely and saw a steaming blue pill lying at the bottom of the elixir.

The elixir is translucent and covered with patterns of water waves, which looks very beautiful.

With a gentle sniff, you can smell the unique medicinal fragrance.

"It's finally done!"

Lu Chen's face was happy and sighed in a long tone.

With this marrow-cleaning pill, Xie Sinian was finally saved.

At this moment, outside the door.

Wang Xuan held the hilt of the sword in both hands, waiting for the battle, and did not dare to relax at all.

Liu Gongquan was pacing back and forth in the living room, looking a little anxious.

Lu Chen had been in seclusion in the alchemy room for a day and a night, and he had not been moved yet, which made him very nervous.

Finally, I got together three top-quality elixirs. If this failure is the case, Xie Sinian will have no way to die.

Because there is no time to find another way.
