The next morning, Zhao Xu reopened the alchemy furnace and tried to refine the "Qi-enhancing Pill" again.

In ancient times, only Taoist priests practiced alchemy.

Few people practice alchemy among the people.

Therefore, for the general public, the technical skill of alchemy is like a space landing on the moon. It is a legendary and unattainable thing.

The folk version of alchemy is even more amazing.

After the failure of the last alchemy, Zhao Xu was very nervous.

But refining alchemy is like a physics doctor doing an experiment. How can you refine advanced elixirs without going through a few failures?

After doing everything, Zhao Xu advised Zhao Han and Zhou Ling to keep them away from the alchemy furnace.

In ancient times, there was a lot of burning furnaces when alchemy was used.

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

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

Zhao Xu replied: "Even if an accident occurs, it is normal. I have not found the real reason for the furnace frying. I was negligent last time and did not observe the alchemy situation carefully. This time, you all help me observe what abnormalities were before the furnace frying? In this way, we can find the real reason for the furnace frying, avoid similar situations and happen again."

Zhao Han and Zhou Ling nodded.

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

He deliberately eased the atmosphere, smiled and said, "Don't be afraid! As long as we are farther away from the Dan Furnace, we will not hurt us."

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

Zhao Xu said "Yes!" and nodded, saying, "Not only wasted time, but also materials. The medicinal materials and elixirs in this alchemy furnace are worth at least several million, which is a pity."

"Fortunately, you have sufficient alchemy materials. Otherwise, if the furnace frying twice will stop because of the lack of alchemy materials."

"yes!"

This is a blessing in disgrace for Zhao Xu.

These alchemy materials are enough to refine more than a dozen furnaces of "Qi-enhancing Pills"

Therefore, even if the furnace blowing incident occurs again, Zhao Xu can still try to continue to refine the alchemy again until it succeeds.

"Let's take turns to guard it! You two will rest first, and I will come to protect the alchemy furnace first. When I rest, you two will guard the alchemy furnace together. Remember, be careful and find the real reason for the fried furnace."

"I understand!" Zhao Han and Zhou Ling nodded respectively.

Spend the next five days safely.

The last time, 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 gave special instructions to Zhao Han and Zhou Ling to cheer up.

You must carefully observe what is abnormal during the alchemy process.

Twenty-four hours a day, Zhao Xu paid the furnace for four hours every time, and then Zhao Han and Zhou Ling paid the furnace for four hours together, and this was repeated.

On the night of the sixth day, Zhou Ling suddenly found a flash of red flashing through the alchemy furnace.

He hurriedly touched Zhao Han beside him and said, "Xiaohan, have you seen that a bright red flashed on the alchemy furnace just now, just like sparks flying out!"

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

Zhou Ling said: "Don't be distracted. The seventh day is coming soon, so don't make any mistakes."

"Yes!" Zhao Han nodded.

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

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

"Yes, it's the burnt smell. The smell is not very big, but it can smell it. Go and wake Brother Xu up." Zhou Ling urged Zhao Han.

Zhao Han hurriedly turned around and shouted at Zhao Xu: "Brother Xu! Brother Xu!"

When Zhao Xu heard Zhao Han's shouting, he got up from a folding bed.

After a quick step, he arrived at Zhao Han and Zhou Ling's side and asked the two of them: "What's wrong?"

"Brother Xu, smell it 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 is only the size of a nail, I can see it clearly."

Zhao Xu sniffed it carefully, and there was indeed a little burnt smell in the aroma of medicinal materials in the sky.

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

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

Zhou Ling pointed to the alchemy furnace and said anxiously: "Did you see it just now? It lights up again."

"not good!"

Zhao Xu's face changed drastically and he hurriedly wanted to turn off the gas.

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

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

The residual medicinal materials in the alchemy furnace were collapsed and flew around.

Zhao Xu used his body to block Zhao Han and Zhou Ling, so that the two girls did not hurt them.

The furnace explosion occurred again, which left Zhao Han and Zhou Ling unsure.

Zhao Xu hurried up and turned off the fire.

After a closer look at the alchemy furnace, a crack broke out.

This is a big loss.

In addition to wasting another furnace of medicinal materials and seven days, a elixir furnace was also built.

The loud noise shook the five clan villages.

At this time, it was around 11 o'clock in the evening.

After hearing the sound of the furnace blowing, Chen Xiaodao hurried towards Danfang.

As soon as I entered the alchemy room, I saw that Zhao Xu, Zhao Han and Zhou Ling were safe and sound, so 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 about Zhao Han and Zhou Ling for concern.

"Are you okay?"

"It's okay!" Zhao Han and Zhou Ling shook their heads at the same time.

Chen Xiaodao walked slowly towards Zhao Xu.

He reached out and patted Zhao Xu on the shoulder, comforted him and said, "Young Master, as long as you are fine!"

Zhao Xu was still thinking without moving.

Seeing this, Chen Xiaodao knew that Zhao Xu was thinking, so he hurriedly gave Zhao Han and Zhou Ling a wink.

The three of them began to clean up the messy elixir house.

Just as I finished packing, Li Qingqing ran over panting and faintly.

Seeing Zhao Xu, Zhao Han and Zhou Ling safe, they 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 herbs and sniffed them in his nose.

He carefully checked the cracks in the alchemy furnace and suddenly shouted, "I know the reason for the failure of alchemy."

Everyone was overjoyed and hurriedly surrounded Zhao Xu.

Zhao Xu said excitedly: "The reason we failed is that there are essential differences in the refining of advanced elixirs and primary Chinese medicines and intermediate Chinese medicines."

Zhao Han asked anxiously: "Brother Xu, what is the difference?"
