Seeing Chen Fei's obscene expression, Nangong Jin's focus was not on how Chen Fei purified and made the evolution potion, but on how many evolution crystals Chen Fei had to use to create an evolution potion.

Nangong Jin and the others also knew the seriousness of this matter, so they couldn't help lowering their voices a few points when they spoke.

They had also been curious about the origin of Chen Fei's evolution potions before, but no one had asked, so they just took this opportunity to ask the doubts in their hearts.

"Chen Fei, how many evolution crystals can you make in the evolution elixir?"

Nangong Jin leaned into Chen Fei's ear and whispered, and Mu Meiqing and Wang Yuanyuan on the side were also curious.

Chen Fei raised his eyebrows in a foolish manner, and did not answer at the first time:

Wang Yuanyuan frowned and pondered for a moment, then stretched out five fingers and was the first to say his guess:

"I heard Sister Crazy Dragon say that the exchange ratio between the general evolutionary team and the laboratory for evolution elixirs is six evolution crystals for one, and their top three teams have the privilege of exchanging five for one, since Sister Crazy Dragon is coming to you now, the lowest exchange ratio should be five for one, so I guess Brother Chen, the evolution elixir you made should also be four or five evolution crystals."

Wang Yuanyuan's analysis was the head of the way, and even Nangong Jin and Mu Meiqing nodded in agreement.

Chen Fei didn't reply to Wang Yuanyuan, but turned his head to look at Nangong Jin and asked with a smile:

"Sister Jin, what do you think?"

Nangong Jin saw the smugness in Chen Fei's eyes, and the corners of his mouth curled up into a sly arc.

"With your character, you wouldn't be so positive without benefits, so I think you should be able to make an evolution potion with just three pills!"

Chen Fei still maintained a smile on his face, turned his head to look at Mu Meiqing and asked:

"Sister Qing, do you think the same way?"

After seeing Mu Meiqing nodding, Chen Fei shook his head helplessly, stretched out a finger to the third girl, and shook it proudly.

The three women's eyes widened in shock, looking incredulous.

Chen Fei revealed the answer at this time:

"One, I make an evolution potion, one only needs one evolution crystal, you must keep this secret, otherwise I will be tied to the Kyoto safe zone as a guinea pig, cut into dozens of pieces for experiments, or directly let me make a numb refining machine."

"A !!"

This answer made the three girls gasp in unison, and Wang Yuanyuan even almost exclaimed, but fortunately, Mu Meiqing on the side reached out and covered her mouth.

Nangong Jin squinted at Chen Fei, wanting to see from Chen Fei's face whether Chen Fei was deliberately lying, but Chen Fei's face did not have any lying except for smugness and stinky fart, and his eyes did not flicker.

This shows that Chen Fei is not lying, everything he said is true!

An Evolution Crystal, Craft an Evolution Elixir!

Chen Fei looked at the shocked and incomprehensible appearance of the three girls, and the smug expression on his face became even more obvious.

Wang Yuanyuan crossed his fingers in the back seat and calculated carefully, and then covered his mouth in surprise, forcibly held back his excitement and joy, and said in a suppressed voice:

"Brother Chen, doesn't that mean that you just earned sixteen evolution crystals from Sister Crazy Dragon and Li Yunfei! OMG! ”

Chen Fei put his finger to his lips and made a silent gesture.

"Actually, the relationship is not bad, I plan to give them a friendship price, three for one, but that Liu Crazy Dragon is too annoying, you have to earn her a few times, as for Li Yunfei.... He's lying down, and he'll slowly compensate him in the future."

Nangong Jin frowned, and pinched Chen Fei's ear:

"Chen Fei, you are a big man who always can't get along with a little girl, isn't it too tasteless?"

Chen Fei looked at Nangong Jin with an innocent face:

"Sister Jin, wronged, it's obvious that little Lori always can't get along with me, it's a big deal that next time she will find me to give her some discounts, three is already the lowest! If it goes any lower, they will definitely be suspicious. ”

Chen Fei's explanation was very reasonable, so he easily persuaded the three girls, and the most important thing is that they all knew the seriousness of this!

The exchange ratio of the safe zone laboratory is five or six evolution crystals for one, and not every evolutionary team can exchange them, Chen Fei is the exchange ratio of five for one, and after the news spreads, many evolutionaries will come to him for exchange, not to mention four evolution crystals or even three for one.

Once the news is leaked, it will definitely cause a sensation, and Chen Fei will also be pushed to the most dangerous place on the cusp, people will be curious about how he did it, and he may do whatever it takes to answer this question!

"Brother Xiao Chen, it's time for us to go! The rest of the teams are gone! ”

Wu Gang's voice came from the walkie-talkie.

Hearing Wu Gang's voice, Nangong Jin and the others regained their calm, and with the start of the car, Chen Fei's survival team finally set off to return to the safety area of Xiaosang Mountain.

After all the teams in the local safety zone had left one after another, the group of three people walked out of the woods on the hill and watched the convoy march away.

"It's good to run fast, otherwise we would almost be affected, these bugs are far more terrible than we imagined!"

A young man touched his forehead, which was not in cold sweat at all, and said with palpitations.

"The people who left by helicopter should all be safe zones in Kyoto, right?"

A tall bearded man with an iron bucket on his back guessed with his right hand stroking his beard.

The young man who was the first to come out was wearing a white suit and a pair of white leather shoes on his feet, revealing a strange feeling of being out of place with his surroundings from that point of view.

If you look closely, you will also find that there is a faint mist around the young man's body, which only floats within a meter of his body, and the two men next to him and beyond have no mist at all.

The man listened quietly to the words of the other two before he slowly spoke:

"Monk, you open the container to confirm the condition of the sample!"

The monk in the mouth of the man in the white suit is the bearded bald man with an iron bucket on his back.

The monk wiped his beard indiscriminately, he was the oldest of the three, and he looked the most fierce, but he didn't dare to disobey the words of the young man in a white suit in front of him.

He put the iron bucket he was carrying on the ground behind him, frowned subconsciously, and said to himself in a deep voice:

"These little bugs have sharp mouths, I'd better be safe!"

As he spoke, one of the arms of the bearded man named Monk began to change, and the originally thick arm continued to swell into the shape of a crab claw, and the huge red crab claw was covered with dense triangular spikes, which looked very hideous and terrifying.

"Monk, isn't it just a little worm, you can still be so careful? You're so sorry for your fierce appearance! ”

Another young man looked at the monk's actions and said with a disdainful face, this young man's face was pale, the pupils of his eyes were much smaller than normal people, and he could still smell the faint rancid smell of the young man when he was closer.

In the face of the young man's verbal ridicule, the monk still did not show any angry expression, you must know that as early as two months ago, with the monk's fiery personality, someone dared to talk to him so cynically, he would have thrown a big mouth over, and he would never stop if he didn't beat the other party all over the ground to find his teeth.

No one will call him a monk before the end of the world, and people on the road prefer to call him Brother Leopard, this title was given to him by those people in the City of Evolution later, in a way, Brother Leopard is dead, and there are only monks in the last days!

After the zombie virus outbreak and the apocalypse came, he could still maintain his arrogant attitude in the face of ordinary survivors and monks, but in the face of those who were stronger than him, he could only choose to humble and bow his head.

The monk first grinned at the young man, and then said helplessly:

"Crown, I can't compare with you, you're a corpse, the body of a half-corpse doesn't know pain, I know how many pounds and taels I have, so I'd better be careful!"

The pale young man named Wang Guan turned his head with a disdainful expression, took out a blood bag from the backpack behind him, and moved so skillfully that after inserting a straw, he began to inhale it slowly.

The corners of the monk's mouth twitched, he was just envious of the ability of the corpse, in fact, he was very resistant in his heart, unlike his beastly evolutionary, the corpse was more like a monster, they inherited many characteristics of zombies, as long as they didn't shoot their heads, they wouldn't die, they didn't know pain, they didn't know fear, and they could only eat fresh flesh and blood.
