Early the next morning, Zhao Xu reopened the pill furnace and tried to refine the "Qi-increasing Pill" again.

In ancient times, only Taoist priests made alchemy.

Few people among the people make elixirs.

Therefore, for the general public, the technical activity of alchemy is like a space mission to the moon. It is a legendary thing that is out of reach.

The folk version of alchemy is even more mysterious.

After the failure of the last alchemy, Zhao Xu felt very uneasy about this time.

But refining elixirs is like a physics doctor doing an experiment. How can you refine high-level elixirs without experiencing several failures?

After doing everything, Zhao Xu told Zhao Han and Zhou Ling to stay away from the alchemy furnace.

In ancient times, there were frequent explosions of alchemy furnaces.

Therefore, our country invented "Gunpowder!" and became one of the four great inventions. Therefore, alchemy is a very dangerous thing.

Zhao Han asked Zhao Xu worriedly: "Brother Xu, will there be no more accidents during this alchemy refining?"

Zhao Xu replied: "Even if an accident occurs, it is normal. I have not found the real reason for the explosion of the furnace. I was negligent last time and did not carefully observe the alchemy situation. This time, you all help me observe, before the explosion of the furnace

What's abnormal? In this way, we can find the real cause of the furnace explosion and avoid a similar situation from happening again."

Zhao Han and Zhou Ling each nodded.

Zhao Xu was a little scared when he saw Zhao Han and Zhou Ling.

Deliberately lightening the atmosphere, he smiled and said, "Don't be afraid! As long as we stay far away from the alchemy furnace, it won't hurt us."

"Brother Xu, if we fail again, we will have wasted half a month." Zhou Ling said.

Zhao Xu said "Yeah!" and nodded. "Not only is time wasted, but also materials are wasted. The medicinal materials of this alchemy furnace plus the alchemy are worth at least several million, which is really a pity."

"Fortunately, you have enough alchemy materials. Otherwise, if the furnace exploded twice, it would have been stopped due to lack of alchemy materials."

"yes!"

For Zhao Xu, this is a blessing among misfortunes.

His alchemy materials are enough to make more than ten furnaces of "Qi-enhancing Pills"

Therefore, even if the furnace explosion happens again, Zhao Xu can still try to continue making alchemy again until he succeeds.

"Let's take turns guarding it! You two have a rest first, and I will take care of the alchemy furnace first. While I am taking a rest, you two will guard the alchemy furnace together. Remember, you must be careful to find the real reason for the furnace explosion."

"Understood!" Zhao Han and Zhou Ling nodded respectively.

The next five days passed without incident.

Last time, the explosion of the alchemy furnace occurred on the seventh day. Therefore, according to Zhao Xu's speculation, the time point of six to ten days is very critical.

On the sixth day, Zhao Xu specially told Zhao Han and Zhou Ling to cheer up.

You must observe carefully to see if there is any abnormality during the alchemy process.

Twenty-four hours a day, Zhao Xu works on the furnace for four hours each time, and then Zhao Han and Zhou Ling work on the furnace together for four hours, and so on.

On the night of the sixth day, Zhou Ling suddenly noticed a flash of red in the alchemy furnace.

He hurriedly touched Zhao Han next to him and said: "Xiao Han, did you see that a flash of bright red flashed on the alchemy furnace just now, like a spark flying out!"

"I didn't notice it! I just looked back at Brother Xu."

Zhou Ling said: "Don't be distracted. It's almost the seventh day. Don't make any mistakes again."

"Yeah!" Zhao Han nodded.

Not long after, Zhao Han smelled a burnt smell in his nose.

Said to Zhou Ling: "It seems to have a burnt smell."

"Yes, it smells like burnt food. It's not very strong, but you can smell it. Go wake Brother Xu up quickly," Zhou Ling urged Zhao Han.

Zhao Han turned around quickly and shouted to Zhao Xu: "Brother Xu! Brother Xu!"

When Zhao Xu heard Zhao Han's cry, he jumped up from a folding bed.

With a quick step, he reached Zhao Han and Zhou Ling's side and asked them, "What's wrong?"

"Brother Xu, smell carefully. It seems to have a burnt smell." Zhao Han said.

Zhou Ling added: "I just saw a bright red spark flashing on the alchemy furnace. Although it was only the size of a fingernail, I could see it clearly."

Zhao Xu smelled it carefully, and there was indeed a bit of burnt smell floating in the aroma of medicinal herbs in the air.

At this moment, a bright red spark the size of a fingernail flashed on the alchemy furnace again.

If you don't observe carefully, you won't notice it at all.

Zhou Ling pointed at the alchemy furnace and said urgently: "Did you see it just now? It's on again."

"not good!"

Zhao Xu's expression changed drastically and he hurriedly went to turn off the gas.

Before he could get closer, he heard the sound of "Peng!..." and the furnace exploded again.

Zhao Xu hurriedly turned around to protect Zhao Han and Zhou Ling.

The remaining medicinal materials in the alchemy furnace were scattered everywhere.

Zhao Xu used his body to cover Zhao Han and Zhou Ling, so that the two women were not injured.

The furnace exploded again, leaving Zhao Han and Zhou Ling in shock.

Zhao Xu hurriedly went up and turned off the fire.

A closer look at the alchemy furnace revealed a crack.

This is a huge loss.

In addition to wasting another furnace of medicinal materials and seven days, a pill furnace was also set up.

The huge roar shook the village of the five ethnic groups.

At this time, it was about eleven o'clock in the evening.

After Chen Xiaodao heard the sound of the furnace exploding, he hurried towards the alchemy room.

As soon as I entered the alchemy room and saw that Zhao Xu, Zhao Han and Zhou Ling were safe and sound, I felt relieved.

Zhao Xu was in front of the broken alchemy furnace, holding the remaining medicinal materials in a daze.

Chen Xiaodao first asked Zhao Han and Zhou Ling with concern.

"Are you guys okay?"

"It's okay!" Zhao Han and Zhou Ling shook their heads in unison.

Chen Xiaodao walked towards Zhao Xu slowly.

He reached out and patted Zhao Xu on the shoulder, comforting him and saying, "Master, just hope everything is okay!"

Zhao Xu didn't move, still deep in thought.

Upon seeing this, Chen Xiaodao knew that Zhao Xu was thinking, and hurriedly winked at Zhao Han and Zhou Ling.

The three of them started cleaning up the alchemy room which was in a mess.

As soon as I finished packing, I saw Li Qingqing running over, panting and weak.

Seeing that Zhao Xu, Zhao Han and Zhou Ling were safe, I felt relieved.

Li Qingqing saw Zhao Xu in a daze and was about to walk over.

Chen Xiaodao shook his head at Li Qingqing and signaled her not to disturb Zhao Xu at this time.

Zhao Xu picked up the remaining medicinal materials and sniffed it in his nose.

After carefully checking the cracks in the alchemy furnace, he suddenly shouted: "I know the reason why the alchemy failed."

Everyone was overjoyed and hurriedly gathered around Zhao Xu.

Zhao Xu said excitedly: "The reason why we failed is because there is an essential difference between refining high-level elixirs and primary and intermediate Chinese medicines."
