Ms. Enid brought back the demon hunters from the sea. There were not many of them, only twelve. They all looked relatively young and should have been demon hunters trained later.

Although demon hunters have a relatively long lifespan, they are not completely immune to aging.

Generally speaking, their aging will stop in middle age, which is around 40 years old. Their faces may look a little older, but their body functions remain at middle age. Until the demon hunter reaches the end of his life, they will age rapidly until death.

However, in history, very few demon hunters died of old age, and the vast majority of them died in battle.

These young people were temporarily placed in the care of Melissa. They brought back the witcher's potion formula, and the information has been handed over to Ms. Elena.

Su Ziyu is also in Ms. Elena's laboratory at this moment.

This place looks like a Frankenstein's territory, with a large number of glass bottles filled with all kinds of strange materials, including monster organs, special minerals, and some indistinguishable flesh and blood tissues.

The entire laboratory was filled with supplies, and Ms. Elena, wearing a pair of monocular glasses, was preparing medicine.

"Sir Su? Are you sure this will work?" Ms. Elena carefully put some blood and flesh from a vampire into the flask and whispered, "I have never seen such a formula. Does it really work?"

"Yeah." Su Ziyu nodded without saying much. He was still very confident in the information provided by the system.

It is not difficult to prepare the vampire mutation potion, and the core ingredients come from vampires.

Su Ziyu needs to improve the strength of other demon hunters.

About half an hour later.

Ms. Elena carefully poured out some dark red thick liquid that looked like blood from the crucible. She put it in a glass bottle and handed it to Su Ziyu, saying, "It worked. But I don't know how effective it is."

"It should be fine." Su Ziyu said affirmatively.

The reason is simple.

When Su Ziyu took the bottle of magic potion, the data stream gave some hints.

"Strange Item: Vampire Mutation Potion."

"Effect: This potion can only be taken by demon hunters. It can activate the enhanced ability of the vampire mutation sequence. If taken by anyone other than demon hunters, it may cause death or unknown flesh and blood mutations."

Many alchemical potions can only be taken by demon hunters, and even a sorceress may be poisoned to death if she drinks them.

Even among demon hunters, there are some potions that ordinary demon hunters cannot drink. Only demon hunters from the School of Viper have such a high resistance to poisons.

"You continue to prepare the second and third portions of the medicine." Su Ziyu picked up the bottle and walked out.

soon.

He came to Fantsin's room. The old demon hunter was drawing something with a pen. When he saw him, he waved and said, "Look! This is the transformed form of a high-level vampire! I'm not sure if it's correct, but it looks roughly like this!"

A hideous monster was drawn on a piece of white paper.

It has a pair of huge, broken bat-like wings, terrifying muscles under the dark blue skin, sharp nails on its huge claws, and flesh and blood tissue like barbs extending from its back.

at a glance.

It makes people feel a little chilly.

It is said that a demon hunter once forced a high-level vampire into this form. In this form, the high-level vampire can fly, and both strength and speed are greatly improved.

"It doesn't look easy to deal with." Su Ziyu said with a serious expression.

After saying that, he threw the dark red potion in his hand to Fantesin in front of him.

"What is this?" Fantsin looked at the bottle of blood-like potion curiously.

"A mutation potion." Su Ziyu held the paper and looked at the monster image, and said slowly: "It can allow you to activate the vampire mutation ability and gain some vampire characteristics."

"Your school's special secret medicine?" Fantsin asked carefully while holding the bottle. Every demon hunter school has some special potions, just like the one used by the Viper School to freeze people into ice sculptures. The Raven School also has similar special potions.

"Yeah." Su Ziyu nodded.

After listening to this, Fan Xin unscrewed the bottle and drank it in one gulp.

Next second.

His body began to tremble violently, and his muscles seemed to wriggle and undergo some unknown changes. Then a trickle of blood flowed from his nose, and when he opened his eyes again, his pupils had turned blood red.

Heavy gasps and roars were heard.

Click.

Fantsin crushed the edge of the bed directly. His whole body was twitching constantly and he seemed to be in more and more pain. However, the old witcher had a strong willpower and he actually endured it.

Unknown mutations are ongoing.

Fantsin's blood-red pupils gradually changed. The white part of the eye became larger and larger, while the central pupil shrank into a small dot and the color became darker, eventually turning into a dark red.

“It’s amazing!”

"My injuries seem to have healed!"

When the entire mutation was gradually completed, Fantsin stood up with an incredible look on his face and said, "What a powerful potion! It's easier to bear than the trial potion!"

The changes in the body gradually stabilized.

Fantsin stood up in high spirits, then frowned and looked at his sharp fingernails, chuckling, "This is not suitable for holding a sword!"

"Just cut it off." Su Ziyu said to him, "Come out. See if there is any change."

Without a doubt.

The vampire mutation potion unlocked by the Spacetime Supervisor System is more stable and effective than the potions in this world. Melissa's trial potion took two or three days to fuse, but Fantsin succeeded in less than half an hour. Su Ziyu judged that there might be demon hunters in other worlds, and the corresponding potion strengthening system is more advanced than that in this world.

The opponent that Fantsin tested was the perch.

The two men only fought for less than ten minutes, but the conclusion they came to was quite shocking!

Fantsin's strength, agility, endurance and recovery ability were enhanced at the same time, with the greatest improvements being agility and endurance, followed by his own healing ability.

The improvement in strength is minimal.

It is very likely related to the fact that the Raven School itself tends to strengthen strength. This kind of strengthening will have an upper limit, and it should not be able to exceed the power level possessed by the vampire itself.

“Incredible!”

"I've never felt so good!" Fantsin looked very excited, and murmured, "My current state may only be comparable to when I took the potion you gave me."

He was talking about Czech-03.

But the side effects of Czech-03 are too serious and should not be used unless absolutely necessary.

After seeing the changes in Fantsin, Su Ziyu became more interested in the Demon Hunter enhancement information that was unlocked after completing the mission.

Because that information may be beyond this era!
