Chen Fan is a person who will take revenge, he has a scale of his own in his heart, and he calculates everything very clearly.

Although Chen Fan did help Black Rock City a lot during his last trip to the main universe, after careful calculation, the person who took advantage of it in the end was himself, and it was even more rare that Feng Li actually traveled thousands of miles to come to the Blue Star World to help, and this intention alone was worth a nuclear crystal.

"Thank you!" Feng Li licked his somewhat dry lips, quickly grabbed the nuclear crystal in his hand, sensing the powerful energy diffused from the nuclear crystal, a fanatical smile appeared on his face that remained indifferent at all times, "It's such a nice thing, how did you get it?" ”

"Let's talk about it on the road!" Chen Fan felt a little tired in his body, so he shook his head and pointed in the direction of Yunxi City.

"Good!" Feng Li nodded, quickly hid the nuclear crystal, and set off to follow Chen Fan back.

On the way, the two roughly exchanged information, and when Chen Fan learned from Feng Li's mouth that the other party had taken Lin Xi to forcibly break into the Spirit Beast Mountain Range together, and finally found the path to enter the Blue Star World, he couldn't help but be glad in his heart, and sighed and said, "Fortunately, you didn't meet those four guys!" ”

After talking, Feng Li had already grasped the information about Hatian and the others, so he said suspiciously, "These four people you are talking about, are they really so powerful?" ”

Chen Fan and the Blood Clan looked at each other and smiled bitterly, and at the same time shook their heads and said, "Those three fourth-level combat power are still secondary, and the most desperate person is hating the sky, if it weren't for the fact that I still have an artifact left over from the ancient period on my body, I'm afraid this would really be folded inside." ”

Feng Li was shocked, and couldn't help but say, "There are actually artifacts in the Blue Star World, can you let me take a look?" ”

This kind of thing as an artifact, even if it is placed in the main universe, is an absolute rarity, at least with a force of the scale of the City Lord's Mansion, it is impossible to take out the artifact, hearing that Chen Fan can actually control the artifact to retreat from the enemy, Feng Li's heart suddenly appeared a strong curiosity.

Chen Fan didn't agree, shook his head and said, "Every time I urge the Zhenling Pagoda, it takes a lot of essence to consume, I am not in a state of physical strength now, I must find a place to heal and recover as soon as possible, and there will be a chance in the future." ”

"Okay!" Feng Li didn't insist, nodded, and followed him back to the main city quickly.

After returning to the city, Chen Fan didn't go anywhere, and returned to his basement as fast as he could. Zhao Yu and Xiaoya naturally greeted them as soon as possible and asked Chen Fan about his experience for more than half a month.

Chen Fan sorted out his thoughts, said briefly, roughly described his experience, and pulled Zhao Yu aside alone, asked for a few relatively small nuclear crystals from the blood clan aliens, handed them to Zhao Yu and said, "You have just refined the third-level fire, and now the state is not particularly stable, and after absorbing the energy of these nuclear crystals, it is estimated that you can quickly stabilize the realm at the third-level mid-end level." ”

Looking at the nuclear crystal handed over by Chen Fan, Zhao Yu's clear eyes suddenly flashed with incredulity, "Where did you get this thing from, why does it feel more ...... than fire?"

Chen Fan waved his hand and said, "Let's talk about the details later, I still have some nuclear crystals here, which should be able to cultivate another fourth-level combat power for Yunxi City, and I will be in retreat in a while, please contact Zhou Tao and them for me, and the blood clan aliens will distribute the remaining nuclear crystals to them!" ”

After speaking, Chen Fan put aside Zhao Yu, strode into his room, closed the door hard, sat down cross-legged, first adjusted his breathing, tried to calm his nerves, and lowered his head, staring at his lower abdomen, his eyes flickered slightly.

At least half of the core crystal of the Jiuli Clan giant remains, relying on this fifth-level nuclear crystal, Chen Fan is expected to try to impact the real fifth-level combat power, this is a once-in-a-lifetime opportunity, once it is missed, I am afraid it will take several years to capture the opportunity of the next evolution, but the Blue Star World can no longer afford to wait.

"Now that Yang Jian's predecessor has obtained the geocentric elemental seed, it must be okay to break through the fifth-level combat power, if I can also follow him to break through, then there are two high-end combat power in the blue star world in the true sense......"

Chen Fan stared at his lower abdomen, slowly exhaled a long breath in his mouth, a sharp intention bloomed in his eyes, and then he took a deep breath and quickly fell into a refining state.

In the next moment, the nucleus crystal that was urged to vibrate rapidly, and a fiery red light diffused from the surface of the nucleus, and then it all shrouded his body.

"Snort!"

In the moment when the light poured down, Chen Fan's skin immediately made a slight sneering sound, and the violent energy washed out, bringing an unbearable feeling of soreness, under the influence of such a huge amount of energy, the red fire also rushed to the whole body, like a scorching sun, scorching his body frantically.

"Hiss......" Chen Fan gasped in pain, his body trembled quickly, and the blood-colored thick scabs began to wrap around his body, Chen Fan could feel the pure energy diffused in those fiery red lights, and when the energy diffused to the skin, it directly invaded the body quickly along the pores, and even his internal organs were also turned upside down!

"Strange...... Why is the feeling of refining energy completely different from before this time? ”

While his body was suffering severe pain, Chen Fan's heart also flashed with suspicion.

These huge energies were not directly absorbed by him, but differentiated into wisps of red "blood lines", flowing everywhere along the meridians, and gradually precipitated on the surface of Chen Fan's body, which was completely different from the feeling of refining the nuclear crystal at the beginning.

"Is it because my combat power is growing too fast, and my body can no longer withstand such a huge amount of energy infusion, so these energy sources can't help me make the next breakthrough?"

Chen Fan felt deeply puzzled, and the restless blood in his body made him burn inside, and he constantly felt the intense pain of the fire in his hands.

He tried to channel these energies and concentrate them all on the lower abdomen, but even if the energy was forcibly channeled into the lower abdomen, it could not bring Chen Fan's momentum boost, that is to say, Chen Fan's evolutionary path had been temporarily stopped!

"Strange ......" No matter how Chen Fan thought about it, he couldn't figure out what the situation was, and in a panic, he quickly stopped refining the nuclear crystal, but the energy stored in the body seemed to be out of control, and it was still being absorbed by the body all the time, and there was no intention of stopping at all!

"Bastard, what the hell is going on?" Chen Fan's face began to change, he never expected that when he refined the nuclear crystal for the second time, there would be such a big change, and the energy in the nuclear crystal did not help him achieve a leap in momentum, but all poured into the cortex and meridians of the body.

And this kind of indoctrination is not controlled by Chen Fan's will, as if the nuclear crystal has its own consciousness and is not controlled by Chen Fan at all.

"Okay, then I'll see what the hell you're up to!"

Chen Fan took a deep breath and quickly forced himself to calm down, sensing the "out of control" energy in the nuclear crystal, he no longer tried to force but guide, but let these energies run around in his body, which undoubtedly brought Chen Fan more pain, but now, he can only grit his teeth and hold on.

His body became more and more sore, numb, and the energy that was running wildly roared in his body, surging all over every cell in his body, Chen Fan's body began to swell like a balloon, and the green tendons under the cortex burst out, as if they might crack at any time.
