"You're finally back!"

Before Mu Bing'er could let her mind rest, Xu Fang's voice came from outside the door.

"Leaving so much work behind me, but I'm at ease in the inner city!"

Xu Fanggang pushed the door in, wanting to complain about the heaviness of the work, and by the way, praise himself for handling all the work in just one day.

Unexpectedly, it was Mu Bing'er's water cup that welcomed him.

Fortunately, Xu Fang was agile and easily dealt with this "sneak attack", otherwise he would have been hit head-on.

Pity that cup, which has become a venting tool for the eldest lady of the Mu family.

"Miss, I don't sleep until I help you with all the work, and that's how you repay me?"

Although she didn't know why Mu Bing'er lost her temper, Xu Fang would never indulge her eldest lady's temper.

"Xu Fang, can you help me handle these tasks? Do you know how many dangers I have shielded for you? ”

Faced with Xu Fang's incomprehension, the eldest lady of the Mu family immediately told everything that happened in the family meeting.

Mu Bing'er never expected that Xu Fang didn't have any unusual emotions after hearing this.

"This is normal, who can not be moved by the interests involved."

The smile on his face was mocking.

"Maybe one day, I will also betray the Mu family because of huge interests!"

Xu Fang's words surprised Mu Bing'er, and what was even more surprising was that she noticed the "Mu family" in Xu Fang's words, not her.

Just one sentence instantly swept away the haze in Mu Bing'er's heart.

"Don't worry! Father has stopped them, and as long as you don't meddle in the affairs of the mysterious organization in the future, they won't trouble you. ”

"I'm afraid I can't promise you this."

Xu Fang reluctantly rejected her.

"Whether I want to or not, trouble will come to the door. Besides, that man will continue to hunt me down. ”

In fact, as he said, the man in the laboratory would never let him go easily, and besides, he really wanted to use the mysterious organization to unlock the secrets of this world.

"Now I'm most worried about whether that man will be angry and kill me even if he violates the rules."

As he spoke, Xu Fang looked at Sister Twilight with some nervousness.

"Sister Twilight, is there a way to get a Level 4 Adept to do it in the outer city?"

"This organization is too mysterious, I can't guarantee it!"

Twilight senses Xu Fang's concern.

"Don't worry! My mission now is not only to protect Bing'er, but also to protect you! ”

"Protect me?"

"Protect him? How did I not know? ”

This surprised both Xu Fang.

"This is the task ordered by Mu Qingfeng!"

"Brother Qingfeng?"

Mu Bing'er was very surprised by this, she didn't expect that Brother Qingfeng, a fifth-level ability, would care about Xu Fang's safety.

Only Xu Fang knew that the other party also wanted to explore the secrets of the world through himself.

After receiving Sister Twilight's assurance, Xu Fang was instantly relieved, but his worries did not completely disappear.

After all, the best way to protect himself was to have enough strength, so he asked the two of them again about the method of advancing to the fourth level of ability.

"Advance to Level 4?"

Every time Xu Fang asked this question, Mu Bing'er and the two would show embarrassment, as if there was something unspeakable.

This made Xu Fang feel very strange, he had even mastered the method of advancing to a fifth-level ability, why was it so strange when he mentioned advancing to a fourth-level ability.

"What exactly are the requirements for a Level 4 Ability?"

After seeing Xu Fang's serious expression, Mu Bing'er knew that this secret could not be hidden forever.

"Xu Fang, do you know why there is no fourth-level crystal nucleus in the outer city?"

Mu Bing'er didn't give a direct answer, but asked a strange question.

Xu Fang also felt very strange about this.

He had tried countless times to synthesize a fourth-level crystal nucleus with a third-level crystal nucleus, but he had tried many times without success. Obviously, what special materials are needed to synthesize the fourth-order crystal nucleus.

But he asked around, but could not get any information, and finally had to give up.

Xu Fang's conjecture that the secret of the fourth-level crystal nucleus has always been controlled by the inner city, just to prevent the outer city from having the power to overthrow the rule of the inner city.

Now it seems that there is some secret hidden in this.

Seeing that Xu Fang didn't speak for a long time, Mu Bing'er spoke again.

"It's because there is no fourth-order crystal nucleus at all."

"No fourth-order crystal nucleus? So how did Sister Twilight get to Level 4? ”

This answer surprised Xu Fang very much.

In his philosophy, the crystal nucleus is a necessary condition for the advancement of the supernatural, and Mu Bing'er's words completely subverted his cognition.

In response to Xu Fang's doubts, Sister Twilight tells a story.

"In the face of the hunting of alien beasts, the first third-level ability of human beings only appeared three months after the end of the world, although they have the strength to fight against alien beasts, but it is still far from enough."

"But no matter how hard the human race tries, it seems that they can't break through the limitations of the third-level ability, and seeing the human race fall into a desperate situation again, a miracle happened!"

"In a bloody night, a fourth-level alien beast slaughtered the headquarters of a certain organization, even if there were four third-level alien beings in that organization, it still couldn't stop the slaughter of the fourth-level alien beast, and in the end, the entire organization was slaughtered by that fourth-level alien beast."

"The only one who survived was a coward who hid in the ruins and survived, but he was also the first fourth-level ability in the end times."

After listening to Sister Twilight's story, the question marks on Xu Fang's face became even more.

There is no mention of any information about the Rank 4 Abilities in this story.

What's even more weird is that why did that coward hiding in the corner suddenly become a fourth-level ability? What's the secret?

"Xu Fang, how do you think that coward became the first fourth-level ability?"

Xu Fang could not give an answer.

"It's blood! He had absorbed the power of hundreds of people in the organization at that time before he successfully advanced to a fourth-level ability. ”

"You mean, the condition for an advanced fourth-level ability is to devour the power of others?"

Xu Fang really couldn't believe that the way to advance to a fourth-level ability was so weird.

"It's not power, it's devouring other people's lives!"

Sister Twilight's words once again subverted Xu Fang's cognition.

What does it mean to devour life?

"You're asking me to kill?"

Seeing the confusion on Xu Fang's face, Twilight had to explain again.

"You didn't hear the story, the main character in the story didn't kill people. As long as enough people die around you in a short period of time, and you devour enough life force, then you can advance to the fourth level of ability! ”

After listening to Sister Twilight's explanation, Xu Fang's eyes widened in shock, and he was speechless for a long time.

He had thought of countless possibilities, but he had never thought that the method of advancing to the fourth-level ability could be so weird and infiltrating!
