The noobs were leveling up, while Zheng Cheng himself was preparing to find suitable wild monsters to practice his skill proficiency.

A few days later, they appeared in an underground maze.

This place is located in the northern suburbs of the imperial capital, in an underground maze with a large number of wild creatures.

The underground maze has nine floors, and each floor has many territory hearts, which passively recruit monsters from the corresponding plane to descend.

This is also one of the hottest places for professionals to level up in the imperial capital.

Because of the orders from the Elders' Council and the Professional Guild, some powerful professionals will not take the initiative to destroy the heart of the territory.

This is to ensure that there are always a large number of wild monsters in the underground maze for some low-level professionals to level up.

Rookie squatted on Zheng Cheng's shoulder and said, "Brother Cheng, do you still remember Brother Huangjiu?"

"Remember, what's wrong?"

"During the three years we were in Lingmei Fudi, Huang Jiu's daughter Huang Yuyao came back and sent me messages several times, but we were in Lingmei Fudi at the time and didn't receive them."

Rookie said, "After we come out of the Spirit Blessing Land, I will be reincarnated again. When we are free, we will go and give Brother Huangjiu's relics to his daughter."

"Okay."

Zheng Cheng nodded and said, three years ago... no, it should be a few months ago, the big brother Huangjiu who was traveling with them died in a joint sneak attack by the Fallen and the Eagle Country.

Before he died, he asked them to give his belongings to his daughter Huang Yuyao.

Unfortunately, she was not there at that time, and Zheng Cheng and others entered the spiritual paradise afterwards.

They thought that a month was a full three years for ordinary people like Huang Yuyao! They didn't know if the archaeologist named Huang Yuyao was free at this time.

Soon, they arrived at the first level of the underground maze.

The underground monsters here are all LV20 underground spiders. They sensed the presence of Zheng Cheng and the other person and quickly surrounded them.

Zheng Cheng didn't want to get entangled with this group of monsters. Instead, he grabbed the rookie with one hand, spread his body, and rushed directly to the second level of the underground maze.

The underground maze is very large. There are hundreds of people walking from the first floor to the second floor alone, and it is rare to encounter other people.

The purpose of their trip was to find humanoid monsters and improve their skill proficiency while leveling up.

On the third floor of the underground maze, there are wild bear goblins, wild humanoid monsters around LV45.

"Acute gastroenteritis instant outbreak technique!"

In front of the man and the chicken, oh no, the man and the pheasant, the seven or eight wild bear goblins that were originally rushing towards them aggressively immediately covered their stomachs and screamed.

Zheng Cheng’s spiritual attribute is now as high as 700+ points, more than ten times that of this group of wild bear goblins.

The group of wild bear goblins were instantly hit by an acute gastroenteritis outbreak. In addition, they usually liked to eat carrion, so they all fell to the ground screaming.

Many wild bear goblins were erupting and screaming, and a large amount of sticky blood was also sprayed out.

"Fuck..."

Seeing this miserable scene, the rookie’s eyes widened immediately.

Fortunately, they had Zheng Cheng's penicillin bacteriophytic shield to isolate the air, otherwise he would have vomited out the Tai Sui meat he had eaten a few days ago.

Even so, he quickly closed his eyes and dared not look again.

But in my ears, I could still hear the screams of a large number of wild bear goblins.

Another large group of wild bear goblins rushed over, and another acute gastroenteritis instant burst spell was thrown out.

His acute gastroenteritis instant outbreak technique has reached level 5 and is almost at level 6.

I don't know what features it will have by then? Besides that...

Zheng Cheng threw another adrenaline stimulation spell.

“Wow!”

"Gah!"

A group of wild bear goblins that were lying on the ground suddenly screamed, and stood up with their difficult bodies and sticky legs, and rushed forward aggressively, regardless of the blood that kept flowing from their legs.

Adrenaline stimulation technique is about to reach LV3, and he is looking forward to the awakening characteristics at LV3.

"Mental confusion technique!"

The newly learned mutation skills revealed their sharp fangs at this moment.

The first wild bear goblin, who was originally rushing towards Zheng Cheng with great momentum, suddenly let out a strange cry, turned around abruptly, and hit another member of the tribe on the head with his mace.

The wild bear goblin screamed immediately, turned around and fought with the attacker.

"Mental confusion technique!"

"Mental confusion technique!"

"Mental confusion technique!"

With the blessing of divinity, Zheng Cheng's skills are almost instantaneous, there is no such thing as CD at all.

Among this group of wild bear goblins, more than a dozen of them started fighting each other.

Acute gastroenteritis instant outbreak surgery.

Adrenaline stimulation.

Mental confusion technique.

These three completely different skills have such strange effects.

Dozens of wild bear goblins were screaming and spraying, while fighting fiercely with their own kind.

They pounced on each other and attacked their fellow tribesmen with their maces, teeth and claws.

For a moment, screams, roars, and biting sounds were endless, like hell.

Hearing the screams in his ears, Rookie quietly opened his eyes, and was immediately shocked by the scene in front of him.

"Guga... Brother Cheng, you are so awesome!"

Dozens of wild bear goblins were fighting hard under the influence of three mutated skills with completely different effects. Zheng Cheng then tried several other skills.

"Three corpses and nine insects!"

"Skin Explosion Technique!"

“Rabies Burst Technique…!”

Ten minutes later, all of these dozens of wild bear goblins were dead, and their bodies were all lying together like a garbage dump.

The area around the pile of corpses was filled with filth and sticky blood, which looked extremely miserable.

Not long after, another group of professionals who came to the underground maze to level up arrived here.

"What the hell! What the hell, it stinks!"

"Ugh...I'm going to vomit!"

"Ah... So many dead bodies of bugbears."

"Use wind magic quickly to get rid of this smell... Ugh..."

“Run, run…!”

For more than a month, a terrifying legend spread throughout the underground maze.

An epic warrior who has comprehended the rules of 'smell' has entered the underground maze and is getting familiar with the power of his domain!

At first, it was just the third level of the underground maze, which was filled with an unbearable and horrible smell. Countless wild bear goblins were stinked to death by this horrible smell!

After seven days, the smell field moved to the fourth level.

Nine days later, the scent field moved to the fifth level.

Twelve days later, the scent field moved to the sixth level...

The epic strong men in the field of terrifying smell kept moving, causing the entire underground maze to boil.

Countless wild monsters were killed by the unbearable smell in the smell field, and the professionals ran away, fearing that they would be killed by the same smell as the wild monsters in the underground maze.

The instigator of all this is, of course, Zheng Cheng! Over the past month, he has been releasing skills and practicing the proficiency of these skills.

Acute gastroenteritis instant outbreak surgery.

Adrenaline stimulation.

Mental confusion technique.

Three corpses and nine insects!

Skin explosion! Rabies outbreak!

God will not let down those who work hard. After more than a month of practice, the levels of these skills have been improved.

Afterwards, he received a message from Zhao Yunxiao, saying that the item made from the petals of the red spider lily to increase the free skill column had been prepared.

After receiving the news, he immediately brought Rookie back to the imperial capital through the underground maze.

It is worth mentioning that during this month of training, Rookie’s level suddenly jumped to LV49.

Unfortunately, his LV49 breakthrough task was rather difficult, and Zheng Cheng was unable to help, so he could only let him complete it alone.

Imperial capital, Night's Watch branch.

"Sister Yunxiao, is the item ready? So fast?"

"Yes, I gave it to you on an expedited basis."

Zhao Yunxiao smiled and said, "In order to refine this tool for you, I even asked the ancestor of my family to help me."

"The ancestor of Sister Yunxiao's family... a pioneer?"

"Um."

Zhao Yunxiao nodded and said, "The ancestor likes to help the younger generation. After your graduation assessment is over, I will take you to see him."

"Meet the ancestor..."

Zheng Cheng's mouth twitched: "Is this considered meeting the parents?"

"See your head!"

Zhao Yunxiao kicked him out, but Zheng Cheng just endured it with a grimace.

"Here you go, take it and wait until your graduation exam is over!"

With a casual throw, a piece of reddish crystal was thrown towards Zheng Cheng and he grabbed it in his hand.

"Is this the item that can increase the free skill bar?"

Zheng Cheng's eyes narrowed as he looked at the crystal in his hand.

The overall appearance is slightly red and hexagonal. If you look closely, it seems like there are twinkling stars inside.

[Props: Crystal of Red Spider Lily]

[Attribute: Low-level rule props]

[Function: After use, it can add 1 free skill column for the professional]

[Description: A low-level rule item made from red spider lilies mixed with reincarnation crystals and time gaps. It has the function of cleansing the soul and resetting spirituality.]

【Note: Each professional can only use it once. 】

"Can it only be used once?" Zheng Cheng shook his head and said, "Unfortunately, I still have several petals of red spider lilies in my hand. I was thinking..."

"Hey, Sister Yunxiao, what is the time gap? Is it a gap in time and space?"

“No.” Zhao Yunxiao shook his head and said, “It’s somewhat similar, a space crack that can be controlled by professionals.”

"How do I use this?"

"Just crush it."

“So simple?”

Zheng Cheng asked doubtfully, and pretended to crush the red spider lily crystal in his hand.

"Hey wait..."

Zhao Yunxiao stopped Zheng Cheng and said, "Go back to your room, don't do it here."

"By the way, I asked a friend to send you the information about the National Joint Graduation Examination for College Graduates that your class of candidates will take. Go back and check it yourself."

"OK."

"careful."

"What do you mean?" Zheng Cheng asked curiously, "Is this graduation exam difficult?"

"Um."

Zhao Yunxiao nodded and said, "It involves an alien battlefield, a real alien battlefield, the underground cave."

"Underground Cave...Earth Demon Tribe?"

"Well, I have sent you all the specific information and content, and some precautions have also been mentioned in it."

Zhao Yunxiao said, "In fact, according to my original intention, I wanted you to wait for another year like a rookie, but I know the agreement between you and Zhixue, so I can only wish you success in passing the assessment."

"As an elementalist, Zhixue has to compete with other elementalists, which is very dangerous."

"Because of the Spirit Blessing, she has fallen behind other candidates by three years... I hope you can really help her."

Zheng Cheng took a deep breath and said, "Don't worry, Sister Yunxiao, I'll go back first."

"Um."

After returning to the room, Zheng Cheng came to the secret room and sat cross-legged. He first closed his eyes and rested, washing away all the fatigue of more than a month.

Then, he took out the red spider lily crystal.

He took a deep breath, and without any hesitation, he crushed the transformation crystal in his hand.

“Click~”

“Buzz…”

A crisp sound of breaking through the air was heard, followed by a slight buzzing sound.

Under Zheng Cheng's surprised eyes, reddish mist suddenly floated out from the red spider lily crystal, wrapped around his body, and slowly seeped into his body.

The shadow of a red spider lily petal suddenly appeared before his eyes.

In his mind, strands of blood-red threads appeared, following his thoughts and spirit and penetrating deep into his mind.

A blood-red fruit suddenly grew out at the point where two completely different skill trees intersected and entangled.

Sprouting, growing, blooming and bearing fruit, all in one go.

A hollow fruit appeared there.

Zheng Cheng knew very well that the hollow fruit was the new free skill bar.

[You used the low-level rule item: Bianhua Crystal, and you gained a new blank skill bar.]

The reminder from the world's will also woke Zheng Cheng up.

He grabbed with his backhand, and what appeared in his hand was a skill book that was shining with black light!

The appearance of this skill book is like a parchment scroll, with layers of complex patterns painted on the surface, vaguely forming a strange flower.

[Skill Book: Spreading Plague]

[Effect: Use the flesh and blood of living beings to cultivate a specific plague. After spreading, it will infect the target at a very fast speed. According to the different properties of the plague, the target will be caused by cholera, dysentery, typhoid and other diseases. It is highly contagious.]

[Usage restrictions: LV60; Physical 110, Spirit 220; limited to priests, pastors, witch doctors, and sorcerers. ]

This skill book is from the skill tree that was dropped after he killed the hero of the horsefly clan on Gasa Island.

You can only learn it at LV60.

Only now could he learn.

"Spreading the plague..."

Zheng Cheng murmured, and then chose to learn! [You have learned a new skill, Spreading Plague... Zizizi... The skill runes are disordered...]

[System adjustment in progress...Adjustment successful! ]

[You have learned a new skill: Black Death Outbreak! ]

In my mind, a pure black and terrifying skill rune that looked like two fangs suddenly appeared on the empty skill bar.

"What?"

"The Black Death!"

Zheng Cheng exclaimed, his eyes full of shock.

"How is this possible? This mutant skill..."

He quickly checked it out.

[Black Death Outbreak Technique (Internal) LV1: Mutation skill, you have mastered the ability to control the Black Death virus. You can spread the Black Death to a target or a certain area in a short period of time, control its outbreak within an extreme time, and eliminate the Black Death virus at any time.]

"The Black Death... This is known as one of the most horrific plague disasters in history..."

The Black Death is the plague.

Blue Star has also experienced an outbreak of the Black Death. Even during the Cataclysm, due to the invasion of alien races, an outbreak of the Black Death spread to most of the world and caused the deaths of countless people.

It is a highly contagious disease mainly transmitted by Yersinia pestis through rat fleas. It is a natural epidemic disease widely prevalent among wild rodents.

The main clinical manifestations are high fever, swollen and painful lymph nodes, bleeding tendency, lung inflammation, etc.

Plague is highly contagious, and if left untreated, the mortality rate can be as high as 30% to 60%.

Historically, plague was a pandemic that caused a high mortality rate. In the 14th century, it was called the "Black Death" and caused the deaths of about 50 million people in Europe!

This kind of damage and death power is comparable to that of large forbidden spells!

Anyone infected with the plague who is not treated promptly will surely die.

And now, this terrifying virus skill has become Zheng Cheng's skill, and it is performed with spiritual attributes. This...

"A mutant skill that is as powerful as a forbidden spell, this is truly terrifying!"

"Forbidden spell!"

"My mutant forbidden spell!" (End of this chapter)
