According to the records in the diary, Taoist Tongluo refined a total of four pills, and three of them ate them to death, and Xiang Yi found the last one in a box filled with dust in the corner of this alchemy room according to the relevant tips in the diary.

The small box is black and gold all over, looking indestructible. After opening it, it immediately emits a strong herbal aura, which is surprisingly fragrant.

"Good medicine!"

Wang Yuanxi knew that this "Bat Blood Longevity Pill" must have incorporated a large number of heavenly and earth treasures. He could even mention a few medicinal herbs. As an advanced version of the first three, Taoist Tongluo sacrificed his three disciples to refine it. I believe that he had the most investment in this fourth one!

Because it was mentioned in the diary that he had not had much time to refine the fifth pill, and all he could do was to gamble on the self-esteem of an alchemist and to exert as much value as possible in the medicinal materials!

"Is this the last pill refined by Taoist Tongluo?" Xiang Yi stared at the yellow pills as big as Maisu in the box and fell into deep thought. He reached out and smelled the smell of the pill by sniffing the breath into his nose.

Just after smelling it, Xiang Yi felt his mind refreshed, and the lifeless smell in the tomb chamber made him feel uncomfortable for a while.

Even Wang Yuanxi thought this was a good medicine, which made Xiang Yi start to doubt the authenticity of the rumors. He looked at Ah Fu who was hanging on the ceiling and asked, "Is your blood really a great tonic effect?"

"This...how is this possible..." Ah Bat was nervous for a moment.

Obviously, Xiang Yi's words scared the "child".

It hung on the ceiling and began to try to distinguish the ingredients in the pill. Finally, it breathed a sigh of relief: "There is no smell of my blood virus in this pill."

Xiang Yi: "Are you sure?"

Abat nodded, like a chicken pecking at rice: "It's certain and certain."

This answer surprised Xiang Yi.

Lian Diaohu felt depressed: "This was the promised bat blood prolonging pill, why didn't this Taoist Tongluo incorporate Abat's blood when he refined the fourth pill?"

"It may not be that it has not been integrated into my blood." Abat replied: "The blood of our bat clan carries a variety of viruses, but if these viruses leave our body, they will not survive long after time. Moreover, after our blood leaves the body, as the viruses inside die, it will eventually be purified and become a substance like water."

When everyone heard this, they suddenly realized.

In other words, Taoist Tongluo still added Abat's blood, but because the blood expired... it received the so-called "purification".

Then the result is actually very obvious now.

The three disciples of Taoist Tongluo died suddenly after eating the "Bat Blood Longevity Pill" that melted the blood of Abat.

As an alchemist, Taoist Tongluo believed too much about the research given by the Taoist sect, which ultimately led to this disaster.

In fact, when Taoist Tongluo refined the last fourth pill, Ah Bat's blood had expired and there were no viruses in it... So this fourth pill had actually been refined successfully!

But unfortunately, Taoist Tongluo did not have the courage to take the medicine until the last moment of his life.

This reasonable inference put the scene in silence for a long time.

After a while, Diao Hu was the first to break the silence: "He has already stepped into the coffin board with half his foot, why not eat it? If it were me, I would rather fight to the death than try!"

"Because you are not an alchemist, you don't understand the psychology of an alchemist at the level of a great immortal master like Taoist Tongluo."

At this time, Wang Yuanxi said: "What alchemists value most is success rate. Taoist Tongluo sacrificed his three disciples to exchange for this fourth pill."

"He firmly believes that the theory of Taoism is correct, and he is extremely arrogant about his alchemy skills."

"If such a proud person fails the last pill, then the success rate of refining this bat blood longevity pill is 0%... This is something that he cannot accept as an alchemist no matter what."

"If you keep it and don't eat it, then you still have the idea of ​​a 25% success rate."

"I actually made a fuss for such a thing..." Diao Hu was in a complicated mood.

When he heard Wang Yuanxi's words, he felt that he was still too limited in his research on human cultivators.

He has been a pet for the Lord of Fengxue Zhenjun for so long. Since he became the Lord of the Northern Wilderness after the catastrophe, Diao Hu has been looking for the survival trajectory of human cultivators in the past, trying to understand the true thoughts of these human cultivators and find out the real reason why human cultivators perish.

But now it seems that Diao Hu is still a long way from the way to find the truth.

Also in a complicated mood, Xiang Yi covered the black iron box and was about to put it in the inventory. His fingers touched the lower end of the box, and felt a bumpy texture on it.

So Xiang Yi immediately turned the box over and found long strings of tadpole words at the bottom of the black iron box. Rather than words, they were symbols, densely engraved on the back of the box.

Xiang Yi used the system to identify the tadpole talismans at the beginning, and translated them into the four words "The Secret Copy of Danwang".

"What is Dan King's Secret Copy?"

"Congratulations to the lord, this is probably the alchemy experience recorded by Taoist Tongluo! Each alchemist has his own alchemy method, and this method is usually only passed on to his disciples." Wang Yuanxi replied immediately.

"So that's it..." Xiang Yi nodded.

In order to refine the pills, Taoist Tongluo died first, and he himself did not have the courage to eat the last one. During this lonely and painful wait for death, Taoist Tongluo finally carved the back of the black iron box in the form of a tadpole talisman he had learned throughout his life to prevent his skills from being lost.

However, perhaps what Taoist Tongluo did not expect was that just a few years after his death, a major catastrophe occurred in the cultivation world that only targeted human cultivators.

Countless cultivators died.

Instead, Xiang Yi has made a big advantage now.

His alchemy attribute bonus has not been activated. The elixirs refined now can be directly synthesized by the system according to the materials. Those more advanced and complex elixirs still need to be operated through the alchemy furnace.

Now that he has picked up the personal teachings left by Taoist Tongluo, Xiang Yi feels that his path has suddenly become much wider.

"Let's go and go to Tomb No. 4 to have a look."

Xiang Yi was in a good mood at this time, and the gains from visiting the tomb this time were much better than he expected.

When he arrived at the door of No. 4, Xiang Yi stared at the iron door and frowned slightly.
