Hearing Lann's question, Thomas Moreau seemed to have lost part of his brain. He actually tilted his head and thought for a while, then answered Lann in a tone as if reciting a book:

"My name is Thomas Moreau, and here I am on the 18th of the month of Joel, embarking on the greatest project of my life, a project far greater than any I have ever undertaken, because it concerns me personally, me and my son.

When I was young, I was attacked by a monster in the forest. A demon hunter came to my rescue, but I didn’t know that the price he paid for saving me would be my son’s future. The day the demon hunter took my son away, I swore to restore my son to his original state…”

Lann looked strange, looking at the chattering half-human, half-ghost creature in front of him, and suddenly had a bold guess in his mind. He slowly took out the crystal bird skull he bought from Triss and asked tentatively:

"I sympathize with your situation, Mr. Moreau. Demon hunters are a stubborn disease throughout the Northern Kingdom and have troubled my country for a long time. I wonder how far your experiment has progressed so far?"

Facing Lane's question, Thomas Moreau did not respond at all. He was like a player that had been turned off. He continued to recite his experience without any emotion:

"I didn't expect that Jeroen's demon hunter mutation gave him resistance to poison, and ultimately the results I had achieved with other test subjects could not be replicated on him. I was unable to achieve my goal. I wanted to cure his demon hunter disease and return him to normal, but the result was that his mutation became more severe, further enhancing his speed and strength, making him further away from human.

Years of experimentation, research, and hard work, all gone to waste... I wanted to abandon this place and go home. My wife might even be willing to let me go back. I wanted to leave the formula and the mutagen here, let them wither here, just like my dream, just like my son..."

Thomas Moreau did not react to Lan's little move, which made Lan bolder. He brought the crystal bird skull close to his eyes. This magic item has the ability to see through low-level magic illusions.

Through the bone holes that were once eyes, Lan saw -

A translucent outline emitting a faint green light shrouded the void around Thomas Moreu's body.

It was as if he was possessed by something unclean. The outline was like boiling smoke, rising and falling from Thomas Moreau's body in an unstable state from time to time, occasionally revealing a green mist-like arm, occasionally floating out a section of green tattered robe, and occasionally... a mist-like head would rise again from the neck of the flesh.

The facial features on the misty head were also the shape of Thomas Moreau.

The half-human, half-ghost figure continued to tell the story: "I did go home for a while, and Lydia forgave me. We spent the last time together and were buried together.

But what about Jeroen? I have fulfilled my duties as a husband, but I have not fulfilled my duties as a father. How can I rest in peace without curing Jeroen's demon hunting disease? ! "

As Thomas Moreau spoke, the green halo on his body became brighter and brighter, and finally completely detached from his body, forming a hazy, foggy, tattered figure in mid-air - Thomas Moreau.

Lann's left eye was fixed on the crystal bird skull, and his right eye was observing the decaying body of Thomas Moreau, which was now motionless.

He understood that Thomas Moreau had indeed turned into a magical creature, but it was not a zombie at all, but a spirit!

There was once a saying circulating in the countryside: "Before you die, you must take care of your own affairs, say goodbye to your loved ones, write a will, and apologize to those you have hurt, otherwise you will never leave this world."

"Inseparable from the world" means turning into a demon spirit. These ferocious creatures usually appear in the wild, in tombs, or in important places where they were in their lifetime. Some powerful demon spirits retain some of their sanity and memories from their lifetime, such as Thomas Moreau.

The conditions for the formation of a demon spirit are also very harsh, and there is currently no 100% successful case in the world.

Thomas Moreau's awakening was unexpected. Although he spent the last part of his life with his wife, his "guilt" towards his son always lingered in his heart, which made him still entangled with resentment after his death. He eventually turned into a demon spirit and continued his career before his death - curing his son Jeroen Moreau's "demon hunter disease".

In order to achieve this goal, the demon spirit transformed by the centenary sorcerer reattached to his own corpse, opened the coffin, and returned to his laboratory.

He had not been away for long, and Geron, who he had abandoned in the laboratory, was still alive. So the poor demon hunter was once again used as an experimental subject by his father, and the mutation experiment research that lasted for more than a hundred years continued. After such a long period of magic power consumption and high-intensity work, Thomas Moreau was actually on the verge of dissipation.

More than ten years after the original novel, when Geralt visited here again, there were no living things in the laboratory, and Thomas Moreau and Geron Moreau had disappeared long ago.

However, Lan and his team arrived a little early, allowing them to catch up with the operation of the laboratory.

The noise made by Lan and his team when they were dealing with the water ghosts alerted Thomas Moreau who was doing an experiment. As he was short of experimental materials, he used a skilled portal to tie up the two men and the horse.

Now, he used the portal to capture Lan again.

Watching Thomas Moreau muttering about his life like a madman, Lann felt that this was an opportunity.

If it was really Thomas Moreau who had become 'immortal' inexplicably, then Lan could only wonder if volunteering to become a stable donor of Ancient Blood could save his life;

And if it is a demon, although it is difficult to deal with, at least it is no longer unknown.

With a touch of his right hand on the strap of the alchemical backpack, an alchemical bomb triggered by a pull ring was thrown out. It was [Moon Dust]!

[Moon Dust]: Contains silver threads. The dust formed after the explosion can prevent shapeshifting monsters from deforming or make virtual ghost-like monsters appear.

"Virtualized ghost-like monsters" include the demon in front of you!

The Moon Dust suddenly exploded in mid-air. Just like its name, silver dust like moonlight bloomed in mid-air. Lann's eyes, which were not looking through the crystal bird skull, could suddenly see the demon spirit.

And after the Moon Dust, Lann took out the second bomb.

[Magic-blocking gold bomb]!

After completely leaving the body and getting rid of the half-rotten brain, the demon spirit in the air seemed to react much faster. After noticing the small movement here, he glanced at Lann and suddenly let out a sharp scream, causing all the glass in the room to tremble.

Lan, who was facing him, also felt dizzy, and his hand slowed down for a moment in throwing the bomb.
