Lu Yao didn't believe that only he would have adventures in this world, and when a person who should have died twenty years ago appeared alive in front of him at this time, Lu Yao had to wonder if he had experienced any adventures.

In the face of an unknown danger, Lu Yao would not choose to act rashly, especially since Lin Jiayi was still by his side, he didn't want to drag Lin Jiayi into danger because of his momentary recklessness.

Although Lu Yao didn't catch up with Zheng Wenjuan when he left just now, he was able to conclude one thing, that is, the things in the big satchel when Zheng Wenjuan went in before were definitely the raw materials for alchemy, but Lu Yao didn't confirm this matter when Zheng Wenjuan went in at that time, and he didn't make an inference from the garbage Zheng Wenjuan carried until she left.

Zheng Wenjuan must have disposed of the residue produced after Bai Yuhui's alchemy.

When an alchemist refines some elixirs whose ingredients cannot be judged by others from the raw materials, that elixir must be very dangerous, and Lu Yao needs to make his own judgment as much as possible from those residues in order to ensure that the subsequent actions are foolproof.

With a decision, Lu Yao quickly left the hot spring villa and chased all the way out following the smell of the residue that Zheng Wenjuan was carrying.

The smell of those residues can almost be said to be colorless and tasteless for ordinary people, but for Lu Yao, it has a very strong taste, especially Zheng Wenjuan's handling is not very particular, Lu Yao naturally found her whereabouts easily.

chased Zheng Wenjuan all the way out of the hot spring villa and came to a cemetery in the northern suburbs.

"How could she come to such a place, it stands to reason that it shouldn't take so much trouble except for some residues, right?" Lin Jiayi asked with some doubts.

"It's hard for me to judge her intentions for a while, let's follow up and take a look first, but remember not to startle the snake, Zheng Wenjuan has seen us." Lu Yao reminded in a whisper.

Although he also knew that with Zheng Wenjuan's ability, he couldn't find them at all, but he still had to be careful, after all, if Bai Yuhui had any back-ups, Lu Yao didn't dare to guarantee it.

Zheng Wenjuan came to an open area in front of the cemetery, which was the entrance to the cemetery, and it was also a relatively open place.

Lu Yao decided to let Lin Jiayi stay outside the cemetery to be wary of whether Bai Yuhui was coming, but he quietly sneaked into the cemetery and followed Zheng Wenjuan.

"Boom!"

Zheng Wenjuan came to a tombstone, looked around again, and after confirming that there was no one again, she suddenly squatted down quickly, groped on the tombstone for a while, and the sound was not very loud, but it was very loud in Lu Yao's ears, and then Zheng Wenjuan opened the garbage bag and poured all the contents into a crack behind the tombstone.

After doing all this, Zheng Wenjuan got up quickly, groped on the tombstone again for a while, and waited until the crack closed, and then left quickly.

This time, Lu Yao did not leave with Zheng Wenjuan, but stayed to find out what Zheng Wenjuan had done just now.

However, for the sake of insurance, Lu Yao did not show up immediately, but waited in place for a while.

Sure enough, Zheng Wenjuan killed a horse pistol, and after leaving, she quickly turned back after ten minutes, and once again confirmed that there was no abnormality before leaving completely.

Lu Yao waited a little longer after Zheng Wenjuan left, but he didn't see Zheng Wenjuan come back again, so he appeared and walked towards the tombstone.

"I see!"

Lu Yao couldn't see the front of the tombstone from the location where he was hiding before, but when he walked in, he saw clearly that this tombstone was not erected for others, but for Bai Yuhui.

Although the words on the tombstone are scrawled and crude, as long as people are literate, they can still recognize Bai Yuhui's name.

It can be seen from these engraved words that the person who erected the monument was also perfunctory.

Lu Yao couldn't confirm who erected this tombstone, whether it was erected by Bai Yuhui's relatives and friends, or Bai Yuhui himself, so there is no way to verify.

However, this is not important to Lu Yao, what he cares about is what the composition of those residues is.

Lu Yao walked to the tombstone, checked it carefully, and found that although there was nothing obvious special on the tombstone, if you looked carefully, the word "jade" in Bai Yuhui's name seemed a little abnormal.

The tombstone is made of stone, and the other words have become a little dull after the wind and rain, but only the point of the word "jade" is eye-catching outside the pavilion under the sunlight, which is obviously the reason for being touched for a long time.

With this discovery, Lu Yao squatted down and tried to press that point.

No response?

Then screw it and try it.

This time, with Lu Yao's gentle force, the crack that had appeared before finally reappeared.

There was no gust of wind, but a pungent fishy smell came to the face.

Moreover, Lu Yao vaguely smelled a smell of rotting corpses from the smell overflowing from this crack.

"Why did he spend so much effort to let Zheng Wenjuan bring the residue of alchemy here to deal with it?"

"According to my own judgment, even if I pour those residues into the trash can of the Hot Spring Villa, if I don't meet the alchemist of the Immortal Cultivation Realm, ordinary people won't be able to find any problems at all."

"Does he have any secrets hidden here?"

"Since Bai Yuhui is alive, who is buried in this tomb?"

One question after another arises.

couldn't figure it out, Lu Yao didn't think about it, he decided to dig up this place and take a look.

Just as Lu Yao was about to make a move, Lin Jiayi also walked over.

"Zheng Wenjuan has already left, I followed her for about five or six hundred meters and came back when I saw nothing abnormal." Lin Jiayi glanced at Bai Yuhui's name on the tombstone and was stunned for a moment, but since she already knew that Bai Yuhui was still alive, there was nothing to be surprised about, and soon she told Lu Yao about Zheng Wenjuan's departure, and said, "What did you find here?" ”

Lu Yao pointed to the crack in front of him and said, "Zheng Wenjuan poured all the medicinal residue she brought into this. ”

"However, I always felt that she was not doing this to simply dispose of the residue, so I was going to dig this place up and see what it was." Lu Yao said: "Jiayi, you have worked hard for you, you still need to give me a guard around." ”

"Hmm!" Lin Jiayi answered, turned around and left.

After Lin Jiayi left, Lu Yao took out a shovel from his golden ring space and excavated.

Although this kind of behavior is very bad, he always feels like a tomb robber, but for the follow-up plan, Lu Yao can't care so much, and in about ten minutes, he cleared all the soil on the coffin.

At this time, Lu Yao finally understood.

The mechanism on the coffin rotated along with the mechanism on the tombstone, and the crack appeared, and the coffin opened a mouth, and the medicine residue poured into the coffin along the crack.

The soil that Lu Yao cleaned up also carried a lot of residues of medicinal residues.

Although there is no way to identify all the ingredients, it can also be judged that it is a prescription used to refine highly poisonous, this poison is very powerful, ordinary people can kill instantly as long as they touch it, more powerful than the venom of the Cobra King.

Even if you are an immortal cultivator, you will lose the ability to resist after taking it.

Lu Yao gently touched the residue with his fingers just now, and instantly felt a burst of itching on his fingers spread throughout his body, which showed the fierceness of its toxicity.

However, the danger is a little more dangerous, and Lu Yao can finally determine Bai Yuhui's alchemy level.

No matter what Bai Yuhui's strength realm is, his alchemy technique is not similar to his own, those residues can be mixed together to refine highly poisonous things, but if they are separated, they are actually not very powerful, and there are even several medicinal materials that Lu Yao can accurately call out are very common tonic on the market.

"Awesome!"

Lu Yao couldn't help but say.

The composition of the residue was almost checked, and then all Lu Yao's attention was focused on the rotting corpse in this coffin.

Slowly pried open the coffin with a shovel, and a corpse that was still covered with black mist appeared in front of Lu Yao.

With just one glance, Lu Yao was shocked.

"What a good idea!"

Originally, Lu Yao judged by the smell that this was a rotting corpse, but after opening it, Lu Yao immediately realized how outrageous his judgment was.

Lu Yao had seen this thing in the Pingyun Cave of the Tang family in Qingzhou City, and he clearly remembered the words he explained to himself when he left Xinjiang.

This thing is not a rotting corpse at all, but a kind of resentful puppet that has been refined by human sacrifice.

Using a living person full of resentment as an introduction, it is made into a puppet through a special means.

At the beginning, Lu Yao encountered two in the Pingyun Cave, but that method was obviously much more powerful than the one in front of Lu Yao, at least for the time being, it didn't seem wrong.

The two puppets relied on the corpses that died near the dragon's spine in the Pingyun Cave for a living, and they could be said to be ownerless, only because Lu Yao moved the dragon's spine at that time and attacked Lu Yao, but this one was obviously not, Bai Yuhui obviously used all kinds of alchemy residues to raise him on weekdays.

"This thing shouldn't have been fully formed yet, it's just just beginning, and I don't know if Bai Yuhui has a resentful puppet who has really succeeded in cultivating?" Lu Yao said to himself.

Lu Yao studied for a while, and did not destroy the resentful puppet, but re-covered the coffin, and then buried the soil on it, and went to join Lin Jiayi after everything was done.

The reason why Lu Yao didn't destroy the resentment puppet was that he knew that this kind of thing generally had a very special connection with the cultivator, and once he made a move to destroy the resentment puppet, even if it was several kilometers away, Bai Yuhui could detect it at the first time.

Striking the grass and startling the snake, Lu Yao didn't think it was a wise move.
