Chu Fei walked all the way, picked up the crystal nucleus, and looked at it carefully.

This crystal nucleus was a little different from what I had seen before, the size of a fist, transparent throughout, and radiating a brilliant green color from the inside.

Feeling the huge energy in the crystal nucleus, Chu Fei smiled slightly, a third-order crystal nucleus could replenish the energy consumed by the restaurant.

After collecting the crystal nucleus, Chu Fei turned around and walked back to the restaurant, set up the tables and chairs that were a little messy due to the vibration before, and came to the back of the counter.

I opened the computer and checked it, and the energy on it barely changed, only one hundred and two drops.

Chu Fei was slightly stunned in his heart, thought for a moment in his heart, and showed an expression of sudden realization on his face.

His own restaurant has been promoted to the second order, that is to say, it is enough to resist the attack of the fourth order, although I don't know how strong the ability of the fourth order is, but it is only the third order, and naturally it will not cause much loss.

Besides, because of Huangquan's skills, the battle didn't actually last long, and all this is understandable.

"It's time to upgrade." The system's computer synthesis sounded, and the tone was obviously very cold, but it strangely revealed a trace of anticipation.

Chu Fei was slightly stunned, he didn't expect the system to take the initiative to speak, you must know that when the restaurant was upgraded before, Chu Fei did not receive any prompts.

"Add in the third-order crystal nucleus, and the restaurant can be upgraded." Seeing that Chu Fei didn't reply, the system was a little anxious.

？？？

Isn't the system full of energy, and how can it be replenished?

Sensing Chu Fei's thoughts, the system patiently explained: "Because the previous turnover requirements have arrived, all that is lacking is energy, so you can now replenish your energy, and these energies will be replenished into the upgraded energy center, and there will be no waste." ”

Chu Fei suddenly realized, pondered for a moment in his heart, took out the third-order crystal nucleus, and reluctantly put it on the counter.

The crystal nucleus that had just arrived was about to be handed over before it was hot, which made Chu Fei a little reluctant.

But Chu Fei had just risen to the second order, and the third-order crystal nucleus was in his hands, so it was not of much use, so instead of being in his hands, it was better to upgrade the restaurant first.

If the restaurant is upgraded to the third order, the defense system can compete with the existence of the fifth order, and the highest level that Chu Fei has encountered now is only the third order.

The fifth order represents invincibility!

A deep black hole slowly appeared in the mouth of the golden toad, and there was a suction force from inside, and the green energy in the crystal nucleus was absorbed and converged into a green match in the air.

In a moment's effort, the crystal nucleus turned transparent, and the energy contained in it was gone.

"Please note that the restaurant will be upgraded in five minutes, please be prepared to close early for business for two hours, due to system maintenance, all functions will be temporarily closed."

As Jin Toad finished absorbing the energy, the familiar voice of the system sounded, Chu Fei was prepared, but he didn't expect the upgrade time to change from one hour to two hours.

But Chu Fei was not too anxious, in the previous battle, he cleaned up the surroundings, as long as there were no accidents, he would not attract too many zombies for a while.

Silently took out a few crystal nuclei from the drawer and put them on her body, Chu Fei glanced at Lin Meng, a little worried in her heart, she had been in a coma for a long time, and she didn't know if something would go wrong.

Five...... Four...... Three...... Two...... One

Five minutes passed in the blink of an eye, Chu Fei sat leisurely on the bone bed, playing with the snake with his mobile phone, and suddenly thought that the restaurant could not use all functions, which meant that it could not be opened.

It's almost dusk, and even though it's past the peak of business, there may still be customers coming, which will affect business.

Thinking of this, Chu Fei felt a little remorseful in his heart, he didn't think clearly before upgrading, how good it would be if it was put in the evening.

More than an hour passed, and no accidents occurred, just like Chu Fei thought before, the surrounding zombies and mutated animals and plants were all cleaned up, and there could be no danger.

Just when Chu Fei's mobile phone was playing, a faint sound came from a distance, although it was very small, but with Chu Fei's second-order senses, he could still hear it very clearly.

Chu Fei paused the game, raised his head suspiciously, and several familiar figures appeared on the road.

Bai Yue took his teammates around him and walked silently on the road, in order to suppress the zombie virus in his body, they had to kill zombies desperately every day and hunt crystal nuclei.

After losing a lot of teammates for such a long time, the people who survived seemed to have transformed from the inside out.

At that time, there were only three or four people in the team of more than ten people, but it is worth mentioning that in addition to Bai Yue, there are two more abilities!

The group walked along the familiar road in the direction of the restaurant, and there was no communication in the process, all of them were tense and guarded around.

When they walked to the realm where Chu Fei and the mutant creeper were fighting in the afternoon, several people were instantly stunned, here, they had just come yesterday, and they were not like this.

The ground is like being bombed, slightly subsided, and it is still full of potholes, and the original few unit buildings have disappeared, and even the original asphalt road no longer exists.

Bai Yue was frightened, for their convenience, the activity area was not very far from the restaurant, and they hadn't heard any sound before, silently, this place became like this.

After hesitating for a moment, Bai Yue glanced up at the restaurant, the restaurant was still the same, but there was no zombie group that usually surrounded the restaurant.

I don't know what happened in the restaurant, but with the owner's terrible strength, there shouldn't be anything that threatens him.

There was no fruit to eat today, and Bai Yue had no other choice, so he could only take a few people and cautiously touch the restaurant.

The soles of his feet stepped on the potholed ground, and there was some stinging, Bai Yue frowned, this felt as if the ground was corroded.

Although a long time has passed since the battle, the remaining power of Huangquan is still corroding the earth.

After a while, Bai Yue walked into the restaurant and saw Chu Fei sitting on the bed playing with his mobile phone, and couldn't help but breathe a sigh of relief in his heart, as long as the restaurant was fine, the rest had nothing to do with him.

"The restaurant is closed for the time being, so come back later." Chu Fei didn't raise his head, he knew that Bai Yue was coming, but the function of purchasing goods was turned off, and there was no spare fruit in the restaurant.

Bai Yue was shocked when she heard this, and said anxiously: "Mr. Chu, why is it not open today?" What about the virus in our body? ”

Pausing the game in his hand, Chu Feiren raised his head and shrugged his shoulders a little helplessly: "The restaurant is out of order, it will take an hour to fix it, or will you wait here for a while?" ”
