My health recovery is incredibly fast.

Xia Zuo nodded in satisfaction, then frowned in thought.

When the Blood Servant mutated just now, it didn't seem to have any side effects besides reducing maximum health...

He hadn't severed his sensory connection with the blood element servant just now because he wanted to see what side effects might occur.

However, when the blood servant mutates, no negative emotions or strange things are transmitted to the mind.

This phenomenon is completely different from what Christo described.

Enough strange things have happened to him.

Xia Zuo didn't want to delve into why he hadn't sensed the negative emotions during the blood magic puppet's mutation. In any case, the truth would likely come to light when he reconstructed the transmigration process.

Xia Zuo calmed himself down and stopped worrying about things unrelated to his current work.

He then concocted dozens of different nutritional pastes and fed them to the blood-element servants in front of him.

After several attempts, Xia Zuo confirmed one fact—once a mutated Blood Element Servant is disbanded, its mutation effect will disappear, and Xia Zuo, as the summoner, cannot obtain any attribute inheritance effect from the Blood Element Servant after it is disbanded.

Therefore... you either need to use reusable beam energy fields to strengthen blood element minions, or you shouldn't disband mutated blood element minions; otherwise, it'll be a huge loss...

Based on the principle that the temple is our home and everyone should save money, Xia Zuo no longer lavishly dismissed the Blood Element servants. Instead, he focused on using the same Blood Element servant for experiments.

After more than two hours of repeated experiments, a table of mutation data formed in Xia Zuo's mind, and he basically understood the mutation limits of the Blood Element Servant.

Suppose he conjures a Blood Element minion with a health pool of 10,000.

After undergoing multiple mutations that significantly boost stats, Bloodborne minions will repeatedly gain mutation talents. Repeatedly gaining mutation talents allows for rapid accumulation of talent experience, increasing talent levels.

Throughout the process, the amount of maximum health consumed increases gradually. Each time there is a mutation, the consumption will increase by 20 points in the next iteration.

A Blood Servant with a maximum health of 10000 can undergo at least 27 complete mutations.

To be on the safe side, Xia Zuo should leave the Blood Elemental Servant with 1000 HP, so he should have stopped during the 26th mutation.

To continue the mutation, there is only one way: increase the minion's maximum health.

When condensing a Blood Elemental minion, the Spirit attribute value consumed * the amount of Blood consumed = the minion's maximum Blood.

Xia Zuo currently has a lot of free attribute points available. If he wanted, he could easily create a Blood Element Servant with a maximum HP of over 10.

But he didn't want to do that.

He was thinking about another question:

Are there any mutations that can increase maximum health or vitality?

This is no ordinary problem.

If such a mutant exists, as long as Blood Element Servants can use it, then Xia Zuo himself should be able to use it as well. At that time, his Vitality attribute value will really skyrocket like a rocket.

He wandered around the materials area in the secret room several times, but unfortunately, he couldn't find the mutant.

However, he did not give up and turned around to knock on Christo's door.

Just then, Krestor finished condensing the third blood magic golem, and the room was filled with the barking of dogs and the meowing of cats.

As soon as Xia Zuo knocked on the door, the area behind the door fell silent.

Christo opened the door, holding a snow-white curly-haired cat in her arms. "Xia Zuo, are you in trouble?"

“Crestor, I have a question.” Xia Zuo looked at the blue-eyed kitten in her arms and then asked, “I roughly know where the mutation limit of my blood magic puppet is. Besides increasing the caster’s own vitality, are there any other ways to break through the mutation limit? For example, using some kind of mutation nutrient paste.”

“Hmm... I understand what you mean.” Christor thought for a moment and said, “You want to temporarily increase your breakthrough limit by strengthening the life force of the blood magic puppet, right?”

“Yes.” Xia Zuo nodded.

“Then you can give it a regeneration potion,” Christo said, “but that’s not worth it. There’s no other way in the temple.”

"Rebirth Potion..." Xia Zuo thought to himself, how could he have forgotten about this? If he could use it, then the Blood Element Servant could definitely use it too. But the price... was just too high.

Xia Zuo pondered for a moment and then asked, "You just said there's no way inside the temple, what do you mean by that?"

Christo scratched the belly of the kitten in her arms, thought for a few seconds, and then said:

"It's like this, Xia Zuo. It's related to a secret. Quamanda himself and his descendants were corrupted by the Church of the Otherworld at the end of the previous era and became flesh alchemists. They possessed the secret formula for mutants that enhance life force. This formula is a mysterious entity within the Church of the Otherworld, and can be said to be the foundation of hybrid mages. But even the deacon of essence and flesh, Nukalofa, had no way of knowing the contents of the formula and could only obtain the finished product from the leader of the Church of the Otherworld."

Chris paused for a moment, then continued:

"The Temple once sent several high-ranking intelligence agents to investigate the secret formula. They all sacrificed themselves, but they still gained something. This is the origin of the Rebirth Potion."

"Just as poison alchemy has always been dedicated to removing the toxicity of highly toxic elemental crystals, potion alchemy has always been striving to restore the specific secret formulas of life force mutants."

"Hmm... The latest development is that the alchemy of potions is stuck on the refining formula for the master-level rebirth potion. If we can find this formula, the rebirth potion can be upgraded indefinitely, ultimately continuously enhancing the life force of the user."

Xia Zuo nodded thoughtfully. "Thank you, Christo."

He winked at the white kitten and then left.

Christo's words gave him great inspiration!

In fact, what he had been dreaming of had always been right in front of him.

The Rejuvenation Potion, something that can boost vitality, was added to Xia Zuo's future research list at this moment.

From the perspective of knowledge of poisons and alchemy, it is not difficult if the goal is simply to refine a master-level novice potion.

The real challenge lies in the fact that the refined potion may be toxic or harmful to the body if ingested. True refinement involves treating it to be non-toxic and harmless while preserving its medicinal properties.

But Xia Zuo suddenly realized that he didn't seem to need to demand non-toxic and harmless refined potions.

He possesses the talent of "Immortal Body". As long as the refined regeneration potion doesn't kill him, he can remove all negative effects when he is at full health and also receive the vitality attribute value rewarded by the potion!

"Oh yeah, why didn't I think of that before..." Xia Zuo slapped his forehead, regretting it in his room.

I have to say, this mission was absolutely worth it.

He not only unlocked the method of strengthening blood minions with mutants, but also found a new way to increase vitality attribute value, thus discovering two significant blind spots.

While feeling remorseful, Xia Zuo was also somewhat agitated.

When moving within the anti-magic field, you'll inevitably encounter otherworldly demons, leading to battles. In that case, [Vitality Recovery] will be able to harvest vitality again…

Thinking of this, Xia Zuo realized that he had to go all out and squeeze every last drop of value out of this adventure.

He took a deep breath and checked the inventory of revitalizing potions in the alchemy stone, intending to use the potions to mass-produce blood element servants.

Plate after plate of mutated monster tissues were carried into the house by him. The furnace of the alchemical cauldron was almost never extinguished.

Chapter 54: Because he was afraid of dying, he maxed out his defense.

Two days later, in the early morning.

Rexol carried a metal box into the secret room.

He knocked on the doors of the pureblood mages one by one, and took their blood magic puppets in metal boxes.

Soon, Rexor arrived at Shazo's door.

A knocking sound came at the door, and Xia Zuo opened it.

Rexor habitually scanned the room, not seeing any blood magic golems resembling cats, dogs, or other small animals, and then asked with slight surprise, "Where are your blood magic golems?"

“Here it is, here it is.” Xia Zuo took out a pendant made of more than 30 small glass balls.

Rexor took the pendant and looked at it, his brow twitching noticeably... Each glass sphere contained a blood element servant comparable to a high-level mage!

He stepped into the room and slammed the door shut behind him. "How did you manage to create so many blood magic golems?!"

"Ah... is that too many..." Xia Zuo rubbed his nose. "How many did Christo and the others refine?"

Rexor opened the metal box on the alchemy table.

The box contained dozens of small squares, each holding a perfectly round glass sphere. Christo and the others' blood magic puppets were stored inside these spheres, totaling about 40, averaging two to three per person… while Shazo alone took out more than 30…

"Cough. It seems like there's a bit too much." Xia Zuo rubbed his forehead.

To ensure he could absorb vitality throughout the process, he was determined to refine enough blood element servants as a backup... but he ended up refining far too many...

“What do we do now… Rexor?” Shazo advised, “Why don’t you take them with you, just in case?”

Rexor brought the pendant close to his eyes to examine it, cast a detection spell on the blood element servant inside the glass sphere, and asked:

"Why are they all blood magic golems with outstanding defensive capabilities?"

“This…” Xia Zuo’s mind raced, and he explained, “I couldn’t control them all, so I made them into defensive blood magic puppets. You just need to wear them like armor to protect yourself from damage. This is much easier than me controlling them myself, and it also increases your survival rate.”

Actually... he was worried that his blood servants would die young or suddenly, so he chose to mutate solely in a defensive direction.

The pendant features over 30 blood-elemental servants, each possessing a maximum health of 2, over 30% elemental resistance, and over 50% physical damage reduction. If these can still be easily killed by the Otherworldly Demons, then there's truly nothing that can be done...

After examining the pendant, Rexor frowned and asked thoughtfully, "You...you created so many blood magic golems all at once, didn't you feel any discomfort?"

"No." Xia Zuo shook his head... Apart from consuming 10 free attribute points and investing them in [Spirit], he had no other expenses.

Rexor took out his cipher ring, sent a cipher, and received a reply two seconds later.

“I would like you to craft five more of these Blood Magic Golems,” Rexor said, setting down the ring. “The infiltration team has 38 people in total. If you craft three more, everyone will be protected.”

"No problem!" Xia Zuo clapped his hands and laughed, "It'll be ready soon."

He ran to the materials area to get the monster mutation tissue, skillfully lit the furnace, and in just one hour, he condensed five blood element servants of the same type.

A total of 38 blood element servants, as hard as steel plates, were sealed in a metal box.

Before leaving, Rexor bowed solemnly to Shazo, tapping his left chest with his right fist and saying:

"Xia Zuo, thank you. If we come back alive, please come to Gray Corner for a visit."

"Uh..." Xia Zuo immediately realized that this mission was extremely dangerous for the infiltrator team when he saw how serious the other party was. He called out to the bald man before he left, "Wait a minute."

Xia Zuo reached into his pocket and pulled out a handful of blood-red diamond fragments. "Take these with you too. They contain my bloodline mark. If I'm in critical condition, I can use the mark to prolong my life. Once I return to the temple for treatment, I'll remove the mark."

Rexor paused, then extended his slightly trembling right hand to take the crimson diamond fragments. "So many...bloodline marks...you..."

Rexor stared blankly at the diamond fragments in his palm until the Message Ring received a message, bringing him back to his senses.

He stuffed the diamond fragments into the inner pocket of his leather armor, gave Xia Zuo a deep look, and said, “Thank you again, Xia Zuo. I will not use your bloodline mark unless absolutely necessary, lest I expose your blood magic talent and attract the attention of the Church of the Otherworldly Demons.”

Xia Zuo nodded and watched the other person leave the alchemy room.

The blood-red diamond fragments bearing the mark of blood ties were something he had prepared long ago, crafted specifically to save lives.

Giving the bald man the blood-red diamond on a whim was partly impulsive, but also partly rational.
