The end of the world: Build a city of sin and take in the school goddess goddess

Huge open-air training ground.

Ji Yi breathed heavily and looked at the dilapidated and gradually recovering doll in front of him, and put away the shadow sword with satisfaction.

The combat effectiveness has increased significantly. Ji Yi feels that it would be perfect if he could fly.

"It would be nice if the skills I extracted later would help."

"System, do you understand what I mean?"

[Do you want to extract skills now? 】

A subtitle flashed before Ji Yi's eyes.

"Extract!"

【Extracting...】

[Congratulations to the host for obtaining: Air Control]

[Skill: Air Control (lv1)]

[Function: When used, it can make itself airborne for 15 minutes (each level can increase the use time by 15 minutes)]

[Upgrade requires 1000 doomsday coins]

Ji Yi's eyes lit up when he saw this skill!

"System, I really love you to death!"

【（*゜ー゜*）】

Ji Yi couldn't wait to try out the air control technique.

His body swayed and began to float in the air. Lin Yu carefully controlled his body and tried to maintain balance in the air.

"Phew - it finally worked."

Looking at himself a few meters above the ground, Ji Yi suddenly breathed a sigh of relief.

It was precisely because of this that Ji Yi's breath was suddenly disordered, he lost his balance and fell down.

After trying many times in a row, Lin Yi was able to fly safely in the air.

The speed is also getting faster and faster.

By the end of the training, Ji Yi's battle in the air was almost the same as on the ground.

Ji Yi felt happy for a moment.

"If I learn the secret technique of using a sword again, I think my strength will increase a lot."

Lin Yiyi followed his heart, and the secret book wrapped in oil paper appeared in his hand.

"System, analyze it."

It is no longer possible for Lin Yi to study carefully with a book in hand. The system is the best helper.

[Consumption of 1000 doomsday coins, analyzing...]

"Why is it so expensive!"

[Analysis completed, optimizing...]

[Optimization successful! 】

[Congratulations on getting: Sword Technique - Qianlang 36 Swordsman! 】

[Skill description: Every time a knife is struck, the skill effect is doubled, up to 36 times! 】

【Do you want to study now? 】

"Yes!"

Ji Yi suppressed his inner excitement and shouted.

Huge amounts of knowledge were poured into Ji Yi's mind, and various techniques for using the sword were mastered by Lin Yi in a matter of seconds.

A familiar yet unfamiliar feeling arises spontaneously.

Ji Yi took out the long shadow knife and began to swing the knife unconsciously.

Layers upon layers of knife waves, like waves, struck out one after another.

The power of each sword is superimposed together, and the power created is naturally extraordinary.

Ji Yi used all his strength but only made eighteen blows, and then felt his arms begin to tremble!

Looking at the mighty, lightning-like sword light, it plowed a deep hole in the empty lawn in front of me.

Lin Yi's eyes were full of surprise!

"If all 36 knives can be chopped..."

Ji Yi is already looking forward to the time when he can chop 36 knives.

"What should we do next..."

Ji Yi touched his chin and started thinking.

Now that his strength has improved, if he wants to continue to improve, he must continue to hunt zombies.

Now it seems that only Sin City can be improved.

"However, Sin City is a bit limited now. As my scope of activities expands, Sin City will only become further away from me in the future..."

Thinking of this, Ji Yi frowned: "And I can't rush back to Haishi every time..."

"So, if Sin City can move, it can follow me around."

A sudden flash of inspiration made Lin Yi think of a solution.

"System, can Sin City be moved if it is upgraded?"

Ji Yi asked impatiently.

[Please host upgrade Sin City to level 20 to unlock related functions]

"Sure enough!"

Lin Yi was happy.

[Sin City: lv10]

[Upgrade cost: 5000 doomsday coins]

Ji Yi looked at the more than 3 doomsday coins on his body and chose to upgrade Sin City to level 15.

[Sin City: lv15]

[Upgrade cost: 7500 doomsday coins]

[Congratulations to Sin City for upgrading to level 15 and activating the defense system! 】

As the system beep disappeared, Ji Yi saw a huge light shield covering Sin City.

[Protective shield: The defense level is linked to the strength of the city lord, and can completely withstand attacks that are lower than the strength of the city lord]

Seeing such a description, Ji Yi felt a little uneasy.

He picked up the long shadow knife and rushed out of the city gate.

"Qianlang 36 knives!"

After slashing five times in a row, Ji Yi watched the defensive shield be damaged and then restored.

The speed of repair is not slow at all.

"Now, the defensive function is guaranteed."

Ji Yi is very satisfied, now Sin City has been basically completed.

Just reach level 20 and see what the so-called mobile function is like.

"At that time, we can pick up Ayina, Agatha and the others, as well as Mei Yuee and the others..."

"I don't know how they are doing now."

……

At the same time, in the military zone.

The captain looked at the middle-aged man in front of him and remained silent.

Ji Jianxun's aura made him feel uncomfortable.

Originally, the captain wanted to tell Ji Jianxun about the mission failure through the telecom, but after much thought, it was more appropriate to come over in person.

"You mean my information is wrong?"

Ji Jianxun's lowered eyes raised, revealing a gentle face.

Although he looks like the kind of frail scribe, the aura of Gujing Wubo exuding from his body makes everyone who faces him dare not underestimate him.

When the captain looked at him like this, he felt as if his body had fallen into an ice cellar.

His teeth were trembling: "I don't dare, it's just that we really didn't find the so-called clues, and..."

The captain told the story in detail about what happened, and also told about the amazing strength of the girls.

"Well, I see, you go down first."

Ji Jianxun didn't say much after hearing this. The captain breathed a sigh of relief and left.

"Someone, bring that experimental subject."

After a while, Ji Jianxun said to the void.

Soon, a strange-looking guy who looked like half human and half zombie was brought up.

If Ji Kun were here, he might still be able to recognize that this person was Ji Kun's lackey.

"There seems to be an error in your message."

Ji Jianxun's indifferent eyes glanced at him, and the man immediately knelt down.

"Commander Ji, everything I said is true!"

"After Brother Kun kicked that kid out, the only thing we observed was the ever-expanding weird building."

"Otherwise, how could a low-level person like him have the ability to fight zombies?"

"You must have obtained something extraordinary!"

Ji Jianxun nodded understandingly when he heard this.

It's not like he has people without earth powers, but it's a bit difficult to build a house.

What's more, a very large villa?

Ji Jianxun subconsciously believed that Lin Yi's villa was a rare treasure.

"It seems that I have to go there myself..."
