After returning to the villa, Lu Chen immediately started making preparations.

The three top elixirs were finally gathered together, and the remaining auxiliary medicinal materials were already prepared.

Next, is the most critical step, refining the Marrow Cleansing Pill.

"Wang Xuan, I'm going to be in seclusion for a day. You should guard it carefully and don't allow anyone to come in and disturb me." Lu Chen warned.

"Don't worry, Brother Chen, even if the King of Heaven comes, I won't be able to enter this door!" Wang Xuan assured, patting his chest.

Lu Chen nodded, looked at Liu Gongquan again, and said: "Miracle Doctor Liu, Uncle Xie will be left under your care. There can't be any accidents before I leave the quarantine."

"Leave it to me. Although I can't cure Mr. Xie's illness, I can still keep him alive for a while," Liu Gongquan said.

"Okay, then I'll leave it to you two."

Lu Chen didn't say much. After explaining a few words, he walked into the temporarily renovated alchemy room alone.

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

However, Lu Chen was not too anxious, but meditated for a long time.

When his whole body was relaxed and his mind was calm, he started to make alchemy.

The Marrow Cleansing Pill is very important and determines whether Xie Sinian can survive.

As a top-grade elixir, its refining difficulty is comparable to the previous life-sustaining elixir, but because of the different types, the details are very different.

Lu Chen has simulated it hundreds of times in his mind, and all the steps are clear.

As long as you don't make mistakes in practice, there should be no problem.

The first step is to install the furnace, followed by setting up the tripod, followed by grinding, burning sand, and solidifying mud. The next step is to control the temperature of the furnace fire, refine and fuse.

Every step is very important and there can be no mistakes.

Lu Chen took it step by step and began to devote himself wholeheartedly to it.

Time is passing little by little.

Lu Chen waited attentively and accurately controlled the temperature of the fire, sometimes fiercely, but sometimes gently.

The elixirs in the alchemy furnace are constantly being refined, fused, refined, and fused again.

Just like that, I don’t know how long passed.

The elixir changes from solid to gas, then from gas to liquid, and finally to solid again.

After repeating this several times, we finally reached the final critical step, condensing the elixir.

Lu Chen took a deep breath and began to activate the Xuanqing Qi, injecting it into the alchemy furnace bit by bit.

Condensing elixirs needs to be guided by true energy, which will not only increase the success rate, but also make the finished product look very good.

"Whoops, whoops, whoops..."

The fire under the alchemy furnace became stronger and stronger, and Lu Chen injected more and more Xuanqing Qi into it.

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

After about a stick of incense, Lu Chen suddenly took action and slapped the alchemy furnace with his palm.

"Bang!"

There was a loud bang.

The lid of the alchemy furnace popped open, and a strong medicinal fragrance immediately spurted out.

Lu Chen took a closer look and saw a steaming blue pill lying at the bottom of the pill furnace.

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

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

"It's finally done!"

Lu Chen looked happy and let out a long sigh.

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

At this moment, outside the door.

Wang Xuan held the hilt of the sword with both hands and stood ready, not daring to relax at all.

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

Lu Chen has been in seclusion in the alchemy room for a day and a night, but there has been no movement so far, which makes him very uneasy.

It took a lot of effort to gather the three best elixirs. If this failed, Xie Sinian would only die.

Because there is no time to find another way.
