Han Sen didn't look at it again after looking at it for a while, but rushed towards the group of firetail butterflies, and collected the golden nuclear light that had been slashed into the Ruthless Bottle, killing all the firetail butterflies he encountered.

These are all good things, and in the future, the promotion of the four natal gene cores to the golden gene core will all depend on it.

The Firetail Butterfly King screamed, and actually abandoned Meow Jun and rushed towards Han Sen, Meow Jun's speed was too different to catch up with the Butterfly King at all, and naturally it was impossible to entangle it.

Han Sen's mind moved, and he directly summoned Meow Jun back, and then threw it at the flying Butterfly King again, and suddenly saw an explosion, Meow Jun was blown out again, and the Butterfly King's attack was also defused.

The Butterfly King seemed to recognize Han Sen, and pounced again and again, Han Sen had the trump card of Meow Jun, and he could temporarily save his life, but he didn't have the energy to collect those golden cores anymore.

Seeing that he couldn't pounce on Han Sen, the Butterfly King seemed to have wisdom, and suddenly turned around and pounced on the weakest of the three, the Stygian Moon.

If it was usual, the strength of the Stygian Moon would still be stronger than Zhuo Donglai, but now that her body has not fully recovered, it is naturally much weaker, and the Butterfly King pounced, she only dodged a blow, and then she couldn't dodge it again, and she was about to be hit by the Butterfly King.

Boom!

Han Sen threw Meow Jun over again, and Meow Jun crashed into the Butterfly King, which immediately caused another flame explosion, just the aftermath of the power, and blew the Stygian Moon out more than ten meters.

"You go first, I'll entangle it. Han Sen shouted at Zhuo Donglai and Styx Yue.

Zhuo Donglai and Shenyue, who had just gotten up, knew that it was useless for them to stay, and that they would only become a burden to Han Sen, so they all turned around and rushed out in the bamboo forest.

"We're waiting for you near the Genetic Nuclear Monument, don't go near the Genetic Nuclear Monument when you arrive. Styx Moon shouted to Han Sen.

"Okay, I'll be over soon. Han Sen answered, grabbed Meow Jun, and threw himself at the Butterfly King who wanted to pursue the Dark Moon.

After entangled the Butterfly King, Styx Moon and Zhuo Donglai gradually moved away and disappeared into the bamboo forest, although there was a group of firetail butterflies chasing them, but ordinary firetail butterflies, they should be able to deal with it easily.

After the Stygian Moon and them were gone, the Firetail Butterfly King immediately poured out all his anger on Han Sen.

Fortunately, Han Sen has a meow king that can be used as a meat shield, and there is no need to be afraid of the Fire Tail Butterfly King, when Han Sen was entangled with the Butterfly King, the sky-covering umbrella in his hand was not idle, and the nearby Golden Fire Tail Butterfly Battle Spirit exploded a lot.

Now Han Sen didn't have time to put the golden nuclear light into the Ruthless Bottle, so he directly asked the Sky Umbrella to absorb them all, only to see wisps of golden nuclear light integrated into the Sky Umbrella, making the Sky Umbrella seem to have become a lot stronger.

At the same time, Han Sen also discovered an interesting phenomenon, although the Firetail Butterfly King was powerful, but every time it collided with Meow Jun and exploded, the blue flames scattered and splashed, and its strength seemed to be weakened partially, although it was a very small part, if you didn't look carefully, you couldn't see that the Butterfly King had become weaker at all, but it had indeed weakened.

After many impacts, it was already obvious that it was much weaker.

"Maybe I have a chance to kill this Firetail Butterfly King!" Han Sen was a little excited in his heart, and while letting Meow Jun entangle with the Butterfly King and consume the Butterfly King's power, he slashed the ordinary Firetail Butterfly and hunted for their genetic nucleus.

Soon, the umbrella absorbed a hundred genetic nuclei of light, and there were faint signs of breakthrough.

Because the all-life gene core is closely related to the natal one, the Sky Umbrella has absorbed so much gene nucleus light, which has also caused the Cave Xuan Sutra in Han Sen's body to surge and circulate, and it has been greatly improved, and he is faintly about to break through the level.

Han Sen knew that once the Cave Xuan Sutra broke through this level, the Sky Covering Umbrella would be promoted to the gold level, but Han Sen didn't do that, and Johnson Sheng suppressed the Cave Xuan Sutra and didn't let it break through.

The Sky Umbrella had just been promoted to the silver level, and he hadn't gone to the silver gene core pool to undergo nine enhancements, so it was too much of a loss to be promoted now, so Han Sen forcibly suppressed the promotion of the Cave Xuan Sutra.

After absorbing a hundred golden core rays, it seems that reabsorption is no longer useful, and it does not continue to make the Sky Umbrella stronger.

Han Sen summoned the crystal nucleus and let it continue to absorb those golden nuclei light, while the crystal nuclei were absorbed, Han Sen also felt that the Ice Muscle Jade Bone Technique was growing rapidly, and after a while, it also reached the edge of promotion, and it was also directly suppressed by Han Sen.

Because there were too many firetail butterflies, there were still a lot of gene nuclei that had not been absorbed, but Han Sen didn't dare to summon the two major gene nuclei of gold coins and true blood to absorb them.

They are still bronze gene cores, once they absorb the golden nucleus light, the energy they get is too huge, I am afraid they can't suppress it at all, and they will be promoted directly.

Suddenly, I saw the fire-tailed butterfly king scream, and a group of fire-tailed butterflies scattered and fled, and it itself rushed into the bamboo forest.

Where is Han Sen willing to let it escape, this is a super gene battle spirit, and now that he has the opportunity to kill, it is absolutely impossible to let it go.

Han Sen didn't care about killing those ordinary Firetail Butterflies anymore, and directly chased after the Firetail Butterfly King.

The Firetail Butterfly King had been entangled with Meow Jun for so long just now, and the strength on his body had obviously dropped a lot, and Han Sen used his Phoenix Flying Secret Technique to chase after him with all his might, but he was not thrown away by the Firetail Butterfly King.

Han Sen used Meow Jun as a cannonball, chasing the Firetail Butterfly King while throwing Meow Jun over, if the Firetail Butterfly King dodged, it would be shortened by Han Sen, and if it didn't dodge, it would be hit by Meow Jun.

After several times in a row, the Firetail Butterfly King was completely enraged, and turned around and pounced on Han Sen again, wanting to kill Han Sen.

Han Sen didn't fight with it, he just used Meow Jun to consume its power, and slowly the strength on its body became weaker and weaker, and after nearly a day and a night, the strength on the Firetail Butterfly King was about to dry up, and Han Sen blasted it over with a punch, and actually blew the Firetail Butterfly King directly.

After the body of the Firetail Butterfly King was shattered, what appeared was not the genetic nucleus light, but a red crystal that seemed to be condensed from the red brilliance, which was no longer a void light, and really condensed into substance.

Han Sen reached out and took the crystal off, and suddenly heard a voice in his head.

"Obtain the nucleus of the firetail butterfly gene. ”

"Is this a gene nucleus, not a gene nucleus?" Han Sen was slightly stunned, this was a bit unexpected to him.

Glancing at the information on the gene nucleus, Han Sen was even more puzzled.

Firetail butterfly: super gene nucleus (mutilated).

"What does it mean to be mutilated?" Han Sen frowned slightly, if the gene nucleus is destroyed, it is also destroyed, or it is possible to scratch it, but he has never seen a mutilated gene nucleus.

And what made Han Sen strange was that this firetail butterfly gene nucleus could not be used, and it could not stimulate its power at all, I don't know what the reason was.

Han Sen didn't have time to study it carefully, and headed in the agreed direction, wanting to catch up with Shenyue and Zhuo Donglai.

After chasing them for most of the day, he didn't see them, probably because Han Sen ran a long distance after the Butterfly King, and there was a deviation in his position, although he also went in the same direction, but took a different path.

Those firetail butterflies didn't know where they had gone, and Han Sen didn't encounter one along the way, and after walking for two or three days, he suddenly heard a sound similar to a piano coming from the bamboo forest in front of him. 10
