All the people in the entire institute are gone, not just the professors. Including his assistants, all of them are gone. Except for the signs of forcible destruction of the gates of the Institute, the rest of the entire Institute was intact, meaning that they were taken away without any violent conflict.

However, Yuhan and the others still investigated carefully, and soon made new discoveries, first of all, they found some residual traces of ghost qi, which was not surprising, but this ghost qi was actually left on the shelves where the specimens were placed in the research institute. Later, Black Egg found that there were some small holes in the ground, which were irregular but oval-shaped, but I found that the round holes in the ground were thicker at the bottom and thinner at the top, that is, the things that drilled these holes were drilled up from under the ground, not from above.

Although I had basically guessed it in my heart, after seeing these two suspicions, I was even more sure that this must be the work of the ghost in the old mansion.

These ghosts must have found out about our help with Professor Du, and they were afraid that he would help us find Dhara wood in the underworld, so they would attack him.

"It seems that we have no reinforcements, and we need to go to the underworld to find the dhara wood ourselves. And it is also necessary to save people, and not let anyone in the institute be harmed. ”

I said with a slight sigh.

The underworld itself is vast and immense, and it is not so convenient to find a tree. Dhara itself must depend on the Yellow Springs River to survive, but if you think that you can find it by the Yellow Springs River, you would be wrong.

Not to mention how long the Yellow Spring is, the root system of the Dhara wood itself is extremely developed, and it is likely to stretch for thousands of kilometers.

That night, I took people into the underworld, in fact, there is another reason for acting so quickly, that is, to avoid the old thing Cheng Yunzi, I promised to give him Bayan Ruyi last time, but I didn't expect to be crushed by my sword, which is not easy to explain, so I can hide.

Lao Gao led people to hide as much as possible, not to cause us trouble, and slowly recuperate and recover. And we who entered the underworld had just walked out of the path of soul attraction when we ran into big trouble.

I actually met a fierce ghost fighting for territory!

This can be described as a rare sight in a thousand years, I don't know if I am too back, but such a rare thing can still be encountered, and it is not a general battle for territory, but a melee of hundreds of ghosts!

In fact, in the past two years, I have indeed heard that the ghosts of the underworld are fighting more and more frequently in order to fight for territory, and I have to blame for this matter. Because, in fact, it's not good for me, after I killed Qinghuo, Tongtian will go on to kill another ghost king in the underworld, and then I went on to kill Guan Cheng two years ago, under the condition that the original underground forces have remained unchanged for a hundred years, three ghost kings disappeared at once, and there was chaos immediately, especially Guan Cheng's territory, which was originally large, as soon as it fell, a large area of no one in the underworld suddenly became vacant, and the surrounding ghost kings immediately began to encroach on this large area, and fierce fights inevitably occurred under his hands.

But I didn't expect that they would still block our way. It is very unwise to break into a fight between ghosts, it is like a person in Africa who meets a lion and is afraid, but if he encounters a group of galloping wildebeests, he is dead! These ghosts have no reason to speak of when they fight fiercely, and they are completely insane. I saw a few minuses standing on the edge from afar, and they didn't even dare to interfere with these ghosts, let alone our group.

But I was originally very short of time to enter the underworld, and now the entire supernatural world, countless pairs of eyes are staring at me, everyone knows that I am investigating the strange case of the ancient mansion, and in the past few days, almost everyone in the supernatural circle knows that I killed Cui Fang. There are even several versions of rumors circulating outside, including a few of Cui Fang's old buddies threatening to kill me.

In the face of this situation, all I can do is to quickly solve the strange case of the ancient mansion and cover up the rumors that were originally directed at me with a more sensational event.

However, the world above won't give me much time, and I have to race against the clock now.

"Stand back, I've got them all in the way!"

I waved my hand, Yuhan and they took a step back, I took a few steps forward, stretched out my hand, in the dark sky of the underworld, there was a light flickering at this time, and then, I saw bright stars in the sky, as if they were winking at me, these stars were like stars flashing in the sky, constantly lit up, and then fell from the sky, illuminating the entire underworld.

At this time, the ghosts in the melee all felt the starlight falling from the sky, they stopped fighting, looked at the light in the sky, and showed a confused look, these ghosts have wandered in the underworld for decades, even hundreds of years, but they have never seen the light in the sky of the underworld.

This is the first time!

But instead of hope and miracle, this light brings destruction! When the starlight fell suddenly, I heard the wails of the ghosts, and as the starlight fell more and more, the hundreds of ghosts in front of me all became miserable in the light, and their souls were also dissipating, as if they were about to be scattered.

A piece of fly ash rose on the black earth of the underworld, and the starlight continued to fall for thirty seconds before stopping, and when the fly ash slowly calmed down, Yin Si, Black Egg, they didn't see a single ghost, hundreds of ghosts, all disappeared in the starlight!

It's a terrifying power, it's the first time I've ever used this starlight, and I don't even know what the name of this spell is, but I know it must have a lot of origin!

The ghosts were all wiped out, and the Yin Si ran backwards in terror, not daring to come near me. I led people into the underworld!

We are no strangers to this black land, but in the past at least we knew where to go and where to go. But this time, I was really lost.

I asked the ghost and the Kabat, but it was useless, they didn't know the location of the tree, and the ghost also told me that the tree had not been seen for many years, and it seemed to be extinct.

However, I knew in my heart that there could be no such thing as extinction, because the ancient house must have been built on the basis of the Dhara tree!

Just when we didn't know where to go, we saw a pair of powerful ghosts in white robes slowly floating in front of us, I glanced at them, they were all at least 50 years of Taoism or more, and the number was estimated to be about forty or fifty. We immediately made preparations for battle, and it was likely that it was the reinforcements who came to avenge the terrible ghosts I had destroyed earlier.

These white-robed ghosts stopped more than ten meters in front of me, and then a ghost who looked to have been practicing for a hundred years floated out and said to me in a hoarse voice: "Mr. Duanmusen, our ghost king invites you to go and see me." ”

I was stunned, I didn't have any intersection with any ghost king in the underworld, how could there be a ghost king who wanted to see me?

"Who is your ghost king?"

I asked out loud.

"Plum Heart Ghost King."

The white-robed ghost said a name that I heard like thunder, Meixin Ghost King, it sounds good to hear the name, but it's not like that at all. It is the only female ghost king among the ghost kings, and it is also the most mysterious ghost king. Mei Xin always covered her face with a black veil, and no one had ever seen it. In its Ghost Army, the ghosts in charge are all women! Moreover, that's not all, its origin is even more mysterious, and many supernatural people in the world speculate that Mei Xin is likely to be a heavenly plum branch turned into a monster, and it was changed after being killed by a strong enemy.

In the world of monsters, it is more difficult for plants to become demons than animals, not only because it is almost impossible for plants to have spiritual intelligence, but even if they have spiritual intelligence, a plant cannot move its position to swallow the essence of the sun and the moon, let alone meditate cross-legged. Therefore, for us humans, we absolutely do not want to meet the monsters transformed by plants among the monsters, and it must be difficult to entangle!

The demons that the monster turned into after death are already very powerful, if Mei Xin is really as rumored by the outside world, it is a powerful ghost turned into a monster of the Tianmei branch that is now extinct, then it must be even more powerful than I imagined.

However, it has always been the most peaceful ghost king in the underworld, and it doesn't like to cause trouble very much, and the ghost kings around it don't dare to mess with it. Because according to legend, more than 400 years ago, there were two ghost kings who teamed up to attack Mei Xin, but in the end, before they could attack it, the ghost army had already suffered heavy casualties and had to retreat.

"I don't have much friendship with your ghost king, I don't know you, and I have something urgent now, please go back."

I don't want to go, who knows if it's a trap, I don't want to jump into it.

"The Plum Heart Ghost King explained that if you don't want to go, it will let you take a look at this thing, and you will go with us."

As he spoke, the white-robed ghost on the opposite side took out a white coat and unfolded it to see that it was similar to the white coat worn by doctors or researchers, and there was a small mark pinned to the chest on the left, which turned out to be the white coat worn by Professor Du's research institute!

At this time, I was surprised, could it be that Professor Du and the people in the institute were taken away by Mei Xin?
