The time passed slowly, and it has been three months since Chen Jiuge became the Vajra of Mountain City.

"Lord Chen!"

"Lord Chen!"

On the underground level, unable to endure the filthy environment, Chen Jiuge used the power of Vajra, utilizing the public account, to carry out a major renovation of the place.

Although the environment remained somewhat chaotic due to the need to treat the wounds of the gladiatorial fierce beasts on the underground level, it was still much better than before!

The staff he encountered all respectfully saluted Chen Jiuge, showing no signs of strange looks due to his low cultivation level.

This was not only because of the Dark Star’s system but also because Chen Jiuge brought them substantial profits.

In just three months, the revenue of the No.1 Arena had almost doubled!

Why? Of course, it was because Chen Jiuge lifted the restrictions on the Fourth Level Beast Masters!

Using the arena’s public account funds to cultivate fierce beasts and allow them to compete with fierce beasts cultivated by Fourth Level Beast Masters, easily surpassing the combat power of the same rank, soon attracted a vast audience.

The abilities of Fourth Level Beast Masters were already related to talent, and ordinary instruments could not detect the strength of the fierce beasts they cultivated, making betting more complicated.

If that were all, more people would only bet on the victory of the Fourth Level Beast Masters, but unfortunately, many Fourth Level Beast Masters would casually cultivate a fierce beast and throw it into the arena for fun, so victory was not certain!

A more elusive outcome could attract more people.

During this period, Chen Jiuge also realized that the spiritual beasts he cultivated could not compete with the fierce beasts meticulously cultivated by Fourth Level Beast Masters.

However, it was almost impossible for Fourth Level Beast Masters to place their meticulously cultivated fierce beasts in the arena.

"Click"

Pushing open the office door, Zhuo Lin and Han Kui, who had been waiting inside, bowed respectfully: "Greetings, my lord!"

"Hmm, Andrew told me, do you two want to become my guard?"

As the Vajra, Chen Jiuge was entitled to form his own Dark Hand guard, and this exclusive guard was no longer under the control of Fang Lei, essentially forming a private army of the Vajra.

Chen Jiuge valued this greatly, but due to a lack of acquaintances, he had been indecisive about forming the guard, temporarily using the guards from the Guard House.

"Yes, my lord!"

"I’ve been at the arena for almost three months now, and during this time I haven’t taken in a single guard. You should understand that I have high standards for my guard!"

"Tell me about your abilities, or perhaps what benefits you can bring me!" Chen Jiuge said lightly.

Han Kui glanced at Zhuo Lin, indicating it was his turn to perform.

Zhuo Lin took a deep breath, stepped forward, and said, "My lord, my name is Zhuo Lin, and I am a Third Level Sinful Doctor!"

"Sinful Doctor?" Chen Jiuge’s eyes showed a hint of surprise.

A Third Level cultivation was not unusual, as among the Third Level guards currently serving in his guard, many expressed willingness to leave the Guard House work to join Chen Jiuge’s guard, but he had been considering it.

The profession of a Sinful Doctor was peculiar, for it not only possessed the healing abilities of a doctor, but also had considerable combat abilities, and even had profound knowledge in transformative medicine, making it an extremely rare profession.

"Strange, you as a Sinful Doctor, are not recruited by others?"

Chen Jiuge couldn’t understand, if other Vajras knew Zhuo Lin was a Sinful Doctor, wouldn’t they want to recruit him? Breaking through from the Third Level to the Fourth Level was difficult for ordinary people, but not for other Vajras.

As long as the necessary resources were provided, it was relatively simple. Once they awakened their exclusive talent, a Fourth Level Sinful Doctor could bring enormous profits, far beyond other professions.

Zhuo Lin showed a hint of a bitter smile, "My lord, although I am a Sinful Doctor, I have no research in human transformation; my main study is biological evolution!"

"Biological evolution!"

Chen Jiuge was somewhat surprised, then thought of the professional information he had zealously studied during this time, and said with some helplessness, "I see!"

Biological evolution is a powerful discipline, but the key is that this is not an ordinary world; this is an Extraordinary World, and a very high-level one at that. The difficulty of studying biological evolution in such a world is absurdly high.

Moreover, the resources required for biological evolution are enormous, and a vast resource investment may not necessarily yield equivalent returns.

The Vajras, while possessing significant resources and wealth, also had large families and many guards to support, making it impossible to allocate large resources; even if they could, they would not gamble on such a small probability.

Zhuo Lin saw the change in Chen Jiuge’s expression and showed a hint of disappointment.

"Forget it, I can accept you, and even invest resources, but you understand that the resources needed for biological evolution are enormous, which I certainly cannot support now, so I can only provide you with basic facilities!"

After some thought, Chen Jiuge still wanted to give it a try; the profession of a Sinful Doctor was indeed very rare!

"Thank you, my lord!" Zhuo Lin said excitedly.

"Hmm, it’s your turn now, Han Kui, right? Andrew told me about your situation!"

"A Fourth Level Mad Warrior, with great strength, but due to offending Yun Yan, ended up in your current situation!"
