When Han Feng stabbed the last knife into the mutant mouse's body, he suddenly felt a stream of heat rising from the position of the dantian and instantly swept through his body.

And when he felt the heat, he shook for a moment, but after a moment, a look of ecstasy appeared on his face.

The last time he fought with a silver-level zombie, the energy in his body had reached the peak of the bronze level, and he faintly began to attack the silver-level level.

And these days of continuous fighting, finally this long-accumulated energy has changed.

The silver-level energy level that firmly locked the dantian part gradually began to collapse under the impact of countless accumulated energy.

The energy accumulated in Han Feng's body was like a flood of waves, and he finally broke through the dam of the silver-level level, and countless energies poured into his blood almost in the blink of an eye, and began to circulate in his body.

"Finally back to the Silver level again!"

Han Feng looked at his hands, clenched his fists vigorously, and then slammed them into the air.

His fist tore through the air, and a violent sonic boom suddenly rang out.

"Well, it's really silver-level power."

When the fist was withdrawn, Han Feng nodded his head with satisfaction, he made a preliminary estimate, now his strength has more than doubled compared to before, if he faces those mutant rats in his current state, he doesn't need anyone's help at all, he can fight the mutant rats in a minute.

And even if the two mutant rats attacked at the same time, at his current speed, the two bronze-level mutant rats besieging him probably wouldn't even be able to touch his sleeves.

However, at this moment, Su Ningxue and Su Chenxi didn't have the time to pay attention to Han Feng's promotion, Su Ningxue only turned her head and glanced at him when Han Feng made a sonic boom, and then locked her eyes firmly on Su Chenxi's body.

As soon as the battle ended, Su Chenxi couldn't maintain his elemental body at all, and the whole person instantly got out of his original giant-like state and changed back to his original appearance.

"Brother, are you okay?"

As soon as Su Chenxi got out of the state of the elemental body, the whole person stumbled and almost fell, and Su Ningxue, who was standing beside him and had been prepared, immediately rushed to his side and hugged him.

The powerful elemental body also has to follow the principle of conservation of energy, and while giving Su Chenxi the strength of a near-silver-level evolutionary, he also continuously draws corresponding energy from his body according to this standard.

With Su Chenxi's current situation, he can only maintain the elemental body for three minutes at most, and then he will become a waste person who has completely lost his combat effectiveness, and he will have to go through at least a day of cultivation before he can reactivate the elemental body, which is one of the reasons why the wandering army can only look at the mutant rat group and stare dryly.

Just as Su Ningxue hurriedly took care of Su Chenxi, who was out of strength, Han Feng's figure had already left the place where the battle had just been fought and appeared next to the corpse of the mutant mouse.

He hadn't forgotten that the mutant rat had a very important thing in it, and that was the core of life.

After killing the mutant rats, he didn't say that he would divide them evenly with the wandering army, so these life cores were his must-take.

With the Life Core, Unimog RV can evolve rapidly.

Truth be told, the Unimog is still relatively unevolving, and while it is strong in attack, it is less than satisfactory in other aspects.

Although its forward speed is much faster than that of ordinary main battle tanks and armored vehicles, the overall speed is still at the level of ordinary vehicles, and there is not a considerable gap with other vehicles.

In terms of defense, although the current armor thickness can block the attack of all light weapons, it is still a thin-skinned dumpling when facing weapons such as main battle tanks and anti-tank rockets, which are specially used against armored vehicles, and those things can penetrate its body armor almost 100%.

Therefore, Han Feng's next goal is to let the mechanical core absorb enough energy to quickly raise the Unimog RV to the silver level.

After Han Feng collected all the life cores, he returned to Su Ningxue's side again, he looked at Su Chenxi, who was paralyzed in Su Ningxue's arms, opened his mouth, and said in a deep voice: "Your current state is very bad, let your sister take you back to Jinxian County to rest first, and then I will solve the two mutant rats alone, and when the battle is over, I will notify Lu Qiao and ask him to send someone to receive these grain reserves that have been entrenched by mutant rats for a long time." ”

"You can take care of those two mutant rats alone?" Su Chenxi, who was extremely weak, did not speak, but Su Ningxue cast a surprised gaze towards Han Feng.

According to her estimates, even if Han Feng is stronger than her, he will not be much stronger, and now Han Feng actually claims to be able to solve the remaining two mutant mice alone, how can this not make her frightened.

Su Chenxi, who was lying in Su Ningxue's arms, with a pale face, raised her head to look at the confident Su Ningxue, and said softly: "Since Mr. Han has the confidence to solve the remaining two mutant mice alone, then Ningxue, you can take me back." ”

Although he was now in the weak stage of the elemental body, he still felt a powerful energy exploding nearby, and when Han Feng appeared, he even felt the extremely dangerous feeling coming from Han Feng's body.

Originally, the key to the cooperation between the two sides was that the difference in strength between the two sides was not too big, and it was impossible for Han Feng at the beginning to swallow Su Chenxi's two siblings at once.

But when Su Chenxi finished releasing the elemental body, he entered a period of weakness.

However, Han Feng was unexpectedly promoted and became a silver-level evolutionary, and the balance of strength between the two sides was broken all of a sudden.

At this moment, if Han Feng had crooked thoughts about Su Chenxi's brothers and sisters, it would take almost no effort to solve them.

Therefore, Su Chenxi agreed to quickly return to the county seat of Jinxian County, after all, there were still a large number of wandering troops stationed there, even if Han Feng wanted to make a move, he had to consider the casualties of his subordinates.

When Su Ningxue supported Su Chenxi and left the reservoir area of the Jinxian National Grain Reserve, Han Feng also asked Wang Yingyu and Da Tang not to make a move, he wanted to personally experience his current combat effectiveness.

As he walked towards the No. 7 Central Warehouse, the mutant rat that was originally hiding in the warehouse also spotted the intruder, let out a sharp hissing sound from his mouth, rushed out of the warehouse, and rushed straight to Han Feng, who was slowly walking towards the warehouse.

At the same time that the mutant rat in the No. 7 central library rushed out, a hissing also sounded in the No. 8 central library on the other side, and a mutant mouse the size of a bull also rushed to Han Feng's side with red eyes.
