The news coming out of the system was like a bolt from the blue, and Seinfeld never imagined that Zhang Han would actually use the E-class virus to advance to an excellent evolutionary.

The longer he was in contact with the system, Seinfeld knew very well in his heart that the evolutionary started from the ordinary, to the excellent, excellent, perfect, etc., and the higher he went, the more difficult it was to advance, and he could advance through the evolution fluid of the system. But for ordinary evolutionists, without this prerequisite, if you want to advance, you can't do without talent, willpower, physical fitness, virus strength and many other factors.

The evolution of the virus is to stimulate the evolution of the virus by constantly devouring and absorbing energy, which has a certain success rate, of course, the disease rate and mortality rate are also super high, so many evolutionaries put the hope of evolution on the scientists, with the help of the virus drugs they studied, although they also have risks, but they are much safer than autonomous evolution.

Whether the virus is strong or not, but it is one of the important factors that determines whether an evolutionary can advance, Zhang Han has just become an evolutionary, he has already reached the level of excellence, his starting point is much higher than many evolutionaries, which is far from being comparable to the talented An An and them.

Seinfeld couldn't wait to check the other party's information.

Name: Han Zhang (Outstanding Evolutionary)

Genetic stage: E grade

Strength: 1135

Reaction: 1040

Spirit: 1048

Special ability: Gravity

"Terrible talent, I've worked hard for so long to have the strength I have now, Zhang Han, this kid is about to catch up with me as soon as he becomes an evolutionary, system, do you say I should replace the E2 virus with the E virus?" Seinfeld smiled wryly, saying this with the intention of complaining.

"The holder doesn't have to be frustrated, since the E2 virus is the end of the virus, of course, it is not comparable to the E virus, it can allow the holder to follow up 100%, as long as there is enough energy value and gene chain, the danger factor is zero, this is an advantage that no evolutionary person has, and the holder can be satisfied."

"Satisfied, very satisfied, it's just that there are too many places to spend, when will we be able to accumulate a huge amount of energy value and gene chain." Seinfeld felt helpless, his next promotion required more than one million energy values and gene chains, which could not be achieved in a short period of time.

"Only when my strength improves again, can I let go of many things to do." Seinfeld's eyes shone with wisdom, and the improvement of his strength was imminent.

"Big brother, look, even if I don't have legs, I can move freely." I saw Zhang Han vacating in the air and coming to Seinfeld.

"Your special abilities are powerful, take advantage of them." Seinfeld wasn't much surprised, gravity was a good thing, and with this ability, Zhang Han was able to move freely, which was reasonable.

"Uh-huh." Zhang Han smiled.

Then, Seinfeld handed the cultivation liquid to Zhang Han, and left the bedroom, except for Heibao, everyone else followed the ancient tree of knowledge to train.

"Black Treasure come here." Seinfeld sat on the couch and beckoned to it.

"Wow!" Hearing this, Heibao happily pounced on the other party with a burst of intimacy.

"Heibao, I'm sorry, I've always let you stay at home, I think you are also eager to fight, to improve your strength, but you are not at home, I don't worry, after holding on for a while, we can fight together, I promise." Seinfeld said earnestly to Black Treasure.

"Wow!" Heibao's eyes flashed and he nodded very humanly.

"System, how much energy is needed to improve the strength of Black Treasure." Seinfeld kept rubbing the black treasure under his feet and asked the system.

"Upgrading Cerberus to D-rank requires 10,000 energy, upgrading to C-rank requires 100,000 energy, and so on."

Seinfeld had almost enough energy on hand, and without any hesitation, he directly raised the black treasure to the C rank.

"Ding! Successfully converted the 1355 gene chain into energy points, and spent 100,000 energy points to upgrade the Cerberus to C level, and began to improve. ”

"Wow!" Heibao suddenly got up from the ground, looking excited.

Soon, the black treasure was digitized in front of Seinfeld, and as it disappeared, a wave of hot and dry air suddenly swept out, as if something terrible was about to come out.

Seinfeld couldn't sit still, this wave of anger made him a little uncomfortable, and hurriedly stood up and walked behind the sofa.

"Ding! Hellhound has successfully evolved to C-rank! ”

"Wow!" The huge figure came out of thin air, and as soon as it saw Seinfeld, it just wanted to pounce, but was stopped by the other party.

"Black Treasure stop, I can't bear your weight now, stay there obediently." Seinfeld was frightened, good guy, the black treasure in front of him was more than two meters tall, and there was a strange flame burning in those huge eyes, except that the size had become larger and the breath had become terrifying, there was not much difference from before.

"Wow!" Black Treasure crouched in place, shouting at Seinfeld.

"My good man, if everyone sees it, they will be surprised." Standing in front of Heibao, even Seinfeld had to look up.

"Big brother, I'm fine." At this time, Zhang Han came to the living room, saw Heibao, and immediately stood on the spot.

After Seinfeld's introduction, Zhang Han eased up, and soon became familiar with Heibao, and he was happy to see one person and one dog playing, so he could rest assured.

Seinfeld quickly sat down to the side and began to communicate with the system.

"System, the evolutionary can absorb their energy value when they kill zombies."

"Yes, it will absorb a small part, about 10%, and the absorption rate is very slow, after all, evolutionaries are different from mutants, mutants can devour flesh and blood with impunity, and the more advanced it is, the more powerful mutants can even devour anything that has energy."

"I think it's unfair to the evolutionary, and it will cause the gap between the strength of the evolutionary and the mutant to get bigger and bigger."

"This is not a problem that the holder should be concerned about, and the system does not feel unfair, the evolutionary itself has an advantage in intelligence over the mutant, in the same level, the evolutionary is stronger than the mutant, this is an era of strong survival, wisdom can create any miracle, there will always be some evolutionary will stand at the top, those eliminated are just too weak, so there is no problem that the holder said."

"What you say makes sense, and I'm speechless." Seinfeld didn't dwell too much on this issue and asked again, "Is there any way for the system to speed up the speed at which the evolutionary absorbs energy?" ”

"Yes, there is an energy harvester in the mall, and 10,000 energy is worth one, which can increase the amount absorbed by the evolutionary to 50%."

"It can only be increased by half, and the other half is not a waste." Seinfeld was clearly not satisfied with this 50% amount.

"It's already very high, and with the energy harvester, there is no problem of waste, and the remaining 50% of the energy harvester will be automatically stored and fed back to the holder."

Listening to the words of the system, Seinfeld couldn't calm down for a long time, the energy harvester was tantamount to a magic weapon for him, just imagine, if An An and they had a collector in their hands, then the efficiency of their own energy value would be increased several times, and they would get stronger and stronger, the stronger it was, the more energy value they obtained, thinking of this, he instantly blossomed.

"Good thing, by the way, the system, since there is an energy harvester, there should also be a gene harvester." Seinfeld has a big heart and will never be satisfied with the energy value, and he doesn't want to let go of the gene chain.

"There are also gene collectors, one for 100,000 gene chains."
