Longfei waits quietly, but he is shocked. Heard the system prompt burst out of things, the heart also had some expectations.

"Finally, we have a system that can be used for system upgrade. I don't know what kind of changes can be brought to the system!" Longfei thought.

"Ding, congratulations to the player on killing the excellent boss Gu Ren, gaining 10 experience points, 1000 energy points, 10 immortality points and 1 invincible point."

"Ding, congratulations to the player on obtaining the Melo system, which can be used for system upgrade."

"Ding, congratulations to the player on killing the superior boss. He has gained 10 experience points, 1000 energy points, 10 immortality points and 1 invincible point."

"Ding, congratulations to the player on obtaining the magic planting system, which can be used for system upgrade."

"Ding, the advanced system is engulfed, which compensates 200 points of player experience."

The sound of the system dropped one after another, and it's only now that it's over.

After a rough calculation in Longfei's mind, 530 points were given for this direct experience, plus the previous 2000, which is 2530. And the energy is even more explosive, giving 35000 points, plus the previous, 37500 points.

For Longfei, it's a great harvest.

After all, he had a deep understanding of the power of energy at the beginning. As long as a little, he could recover his seriously injured body, which shows the strength of this power.

However, Longfei still hasn't moved. At the moment, he is still waiting for the next step of the system.

In the distance, Chen Zhong dare not breathe. The whole floating world has changed completely. It has become a country of blood baptism, which is extremely terrible.

However, this kind of terror is not worth mentioning compared with Longfei.

"This man is absolutely a cruel man. And up to now, they have not shown real strength. His system may even reach the legendary level of transcendence. "

"With this kind of system, the whole seventh world is a master of one side. It's said that the owner of Aoyue palace is just an extraordinary system. "

"That is to say, he is likely to be the next owner of the proud Moon Palace. It seems that in the future, I have to show more loyalty to this person. " Chen Zhong kept thinking about it.

And Longfei, at this time, finally waited for the answer he wanted to get.

"Ding, congratulations to the player on opening the system upgrade mode."

The system voice falls down, and then displays on the dragon flying spirit. It is under the personal level, and there is another experience bar.

However, because this mode has just been opened, there is no experience at all.

Long Fei's eyebrows are slightly wrinkled. This kind of opening doesn't mean anything to him.

A sentence opens, but does not prompt any substantive role. For Longfei, it's all chicken ribs, not eggs.

If you don't know the function, how does Longfei choose?

Thinking of this, Longfei asked directly:

"system, and then

There was a silence.

It seems that there is no reply to Longfei at all.

"System, is this for fun? What do you want me to do if you don't tell me what the system will do after upgrading? "

"If I use all the systems for system upgrade, at last you tell me it's a device? How can I feel? " Long Fei questions one after another.

However, at this time, the system still doesn't have any answers. However, it prompts:

"Ding, players now know that three systems can be used for system phagocytosis. After system phagocytosis, they will become system experience for system upgrade."

"Ding, please choose whether it is used for system upgrade or character upgrade." The system sounds down.

Besides, there is no more words.

Obviously, this is just a choice for Longfei. As for how Longfei should choose, it is no longer concerned.

Longfei's mind sank:

"Damn it, it's just a pit of goods. If only the system sister was there." Long Fei's stomach is full of troubles.

I think of the origin of the system directly.

At this time, there is an impulse in Longfei's heart to give up everything and go directly to find the origin of the system.

Then at all costs to save the system sister, save the face of this system that never takes him seriously.

However, in a second, Longfei's heart was also silent. Now he had to face the problem of choice.

Three excellent systems, Longfei believes that the system will not be so bad that only 10 points of experience will be given to him. If he chooses to upgrade himself, at least hundreds of experience will be brought to him.

"My current level is not low. Although I have 100000 upgrade experience, Chen Zhong also said that there are countless similar to the existence of this dark underground city. That means that there are countless systems below the excellent level, and there is no need to worry about character upgrading. "

"Obviously, the excellent level can be the city Lord. It can be seen that the system above the excellent level is also rare in the world. In this way, I choose to upgrade my system experience, which is the best choice. " Longfei thought.Do what you say.

Longfei has never been that kind of indecisive person, since there is speculation in his heart, there will be no more hesitation.

"System, for system upgrade."

Longfei said.

"Ding, system upgrade experience increased by 3 points." The system sounds down.

For a moment, Longfei was overwhelmed.

Three

After that, Longfei saw the long one in the whole system upgrading experience bar, and finally marked ten thousand, and his heart was completely speechless.

"System Your uncle! " Longfei can't help bursting his tongue.

He's fucked his father.

This kind of data directly shows that if Longfei really wants to upgrade the system, it will have to explode 10000 excellent bosses.

As soon as he thought about this, Long Fei turned around and looked at Chen Zhong: "I asked you, are there 10000 City lords of this level in the dark Council?" Longfei asked.

Chen Zhong's heart was suddenly cold.

There was a huge wave directly:

"this person asked this question, which was definitely planned. What's more, to see the meaning of the evil star is to want a nest of ends. "

"I can't hide something, but I can't do without it."

"Yes, I will lose my value when he brings the city of the dark Council to its end. Yes, that's it. I have to realize my self-worth and sublimate my realm. At least, he can't reveal much until he finishes. Otherwise, the cunning rabbit will die and the running dog will cook. "

Chen Zhong's mind turned sharply. A word from Long Fei directly filled the middle of his mind with the survival history of a small person.

"Your Excellency, the dark Council is very powerful, although you, your excellency, are boundless and powerful. But the villain can't bear his master to risk himself. About those strong existence, the villain would rather die than tell the adults. However, as for those who are equal to the strength of the underground city, the villain will surely lead the way for the adults and let them take revenge. " Said Chen Zhong.

Long Fei: "..."

Long Fei looks at Chen Zhong in front of him with a look of astonishment. He forces him to add ten thousand
