After working busily for an entire night, Ye Bai returned to the lab.

This was a gigantic experimental base, divided into many different zones.

Ye Bai was in charge of the most mysterious Zone 18, and the Pet Beasts in this zone were also of the highest Level.

Among them was the Iron Spear Shrimp King belonging to the gun shark.

The Iron Spear Shrimp King’s condition was quite serious; its cells had already Split to a certain degree.

If they wanted to save the Iron Spear Shrimp King and extend its Life Force, there was only one way: replace every cell in its body.

This was far more difficult than replacing all the blood in its body.

On top of that, Ye Bai also had to repair those two claws of the Iron Spear Shrimp King that were comparable to heavy firearms.

At this moment, Ye Bai suddenly thought of Professor Jubino’s mechanization research. This might be the key path for the Iron Spear Shrimp King to break out of its predicament.

And turning the Iron Spear Shrimp King into a mechanical Pet Beast seemed to match the gun shark even better; after all, gun sharks preferred Pet Beasts in mechanical form.

However, Ye Bai wasn’t very familiar with how to turn a normal organism into a mechanical Pet Beast.

Currently, Professor Wang was the authority on mechanical Pet Beasts, but when Ye Bai thought of transferring Professor Wang over to preside over the conversion experiment, he instead heard the news that Professor Wang had suddenly dropped dead from overwork.

"That really is a pity. With Dr. Jubino’s notes, Professor Wang could have become an expert remembered through the ages."

"Because of the plane merger, the Beautiful Country is busy eliminating outside invaders. Professor Wang’s death should really just be an accident."

Ye Bai pulled up the full record of Professor Wang’s death and found nothing abnormal. The manuscripts Ye Bai had given Professor Wang back then had all been taken over by the Flame Country; at the moment, they were being studied by Professor Wang’s foremost disciple.

But who knew which distant year it would be before that disciple actually mastered them; the Iron Spear Shrimp King couldn’t wait that long.

"Looks like I can only rely on myself to learn it."

For Ye Bai, who possessed a Memory Palace, it took less than an hour to finish digesting all this material.

But understanding the theory was one thing; he still needed practice before he could gain real knowledge.

"I’d better test it on ordinary Pet Beasts first."

Ye Bai knew that if the test failed, it would have unforeseeable consequences for the Iron Spear Shrimp King, so he had to run experiments first.

He pressed a Bell, and the Paperman of the Paper Puppet drifted over.

This was a little assistant the Paper Puppet had specially made for Ye Bai before it went into seclusion.

This Paperman possessed thinking ability far beyond that of ordinary people, like a large-scale computer.

Ye Bai treated it as an assistant and named it Paperman No. 1.

"Paperman No. 1, help me go to the Exotic Beast warehouse and see if there are any Exotic Beasts whose Life Force isn’t that strong. I need one for an experiment."

After receiving the order, Paperman No. 1 instantly turned into countless sheets of paper and dispersed into the air.

It headed to the large Exotic Beast warehouse to pick out Exotic Beasts suitable for experimentation.

Not long after, the Paperman ran back, now holding two Thunder Bulls that were on their last legs.

Thunder Bulls were Thunder Element Exotic Beasts, said to be descendants of the Kui Ox and to carry a trace of Kui Ox bloodline.

Their voices were deafening, like a giant loudspeaker.

[Name: Thunder Bull]

[Gender: Male]

[Personality: Stubborn]

[Level: Tier Five, Stage Three]

[Skills: Great Roar (Mastery): Opens its mouth and lets out a loud Roar, causing the opponent to fall into a confused state.

Stomp (Mastery): Uses its large hooves to stomp the opponent, with a certain chance of sending the opponent into a fainting state.

Charge (Mastery): Uses the huge Unicorn Horn on its head to Charge at the opponent.

Thunder Light (Mastery): A streak of Thunder Light shoots from its eyes to hit the opponent, with a certain chance of sending the opponent into a paralyzed state.

Thunderball (Mastery): Summons a Thunderball to attack the opponent. When the Thunderball hits, it explodes instantly, with power comparable to the Big Bang of a Blast Stone.]

[Evaluation: A Thunder Bull whose bodily lifespan is about to reach its end, but whose willpower is extremely tenacious.]

Turning a Thunder Bull into a mechanical Illusion Beast required three steps in total.

The first step was to extract the Thunder Bull’s Soul.

The second step was to use nanorobots to modify the Thunder Bull’s body, remove the flesh-and-blood parts, and artificially create the Thunder Bull’s physical body.

The third step was to fuse the Thunder Bull’s Soul with its metallic body.

It was like trying to stuff an elephant into a refrigerator.

Except the complexity was on a whole other level.

The first problem to solve was how to extract the Thunder Bull’s Soul.

If this had been before Ye Bai formed a contract with Hastar, he would have been at a loss. If he hadn’t met the Snake-woman Ghost Emperor either, he would also have been at a loss.

The solution Professor Wang and Professor Jubino came up with was to build a large Soul-extraction device to pull an Exotic Beast’s Soul out of its decaying flesh.

This method was time-consuming and laborious, and it would also have a certain impact on the Exotic Beast’s Soul.

Back then, the Steel Giant Dragon created by Professor Jubino had lost control many times before it was sealed at the bottom of a lake, and in the end it took the Sea Demon’s power to calm it down.

But now that Ye Bai had a better way, naturally he would let Hastar take the field.

"Just leave it to me."

Hastar patted its chest as it spoke.

This was exactly the sort of thing it excelled at; it was a powerful being adept at manipulating Souls.

"Thunder Bulls, you can feel it yourselves now—you’re on the brink of death. If you want to go on living, I can give you a chance, a chance to extend your lives. What do you say?"
