Although he still has four cores of will in his hand, Jiang Fei does not intend to fuse them all immediately, there is a way to be quick but not reach, Jiang Fei knows this truth very well, he doesn't want to leave any hidden diseases for himself because of blindly expanding his strength.

After the improvement of his strength came to an end for the time being, Jiang Fei reflexively returned to the center of the training ground, where four biochemical cabins were parked, where Hua Mulan and other girls were fusing the energy core of the primordial stage.

"0541, how are they?" Jiang Fei asked, at this time the four girls were lying quietly in the biochemical cabin, the dark green nutrient solution wrapped their whole bodies, providing their bodies with the necessary energy support.

"Captain, the integration of the primitive stage is very smooth, Ariel and they have completed the initial fusion and are now adapting to the body. 0541 explained.

"How long will it take for them to wake up?" Jiang Fei asked.

"About six hours!" 0541 replied.

"Okay! I see!" Jiang Fei nodded.

Taking advantage of the time when the girls' bodies adapted to the core of energy, Jiang Fei found Bella, who had completed a fusion before.

"How do you feel?" Jiang Fei asked.

"It feels great!" Bella said excitedly.

"That's good......" Although Jiang Fei said this, he was still a little disappointed in his heart, after all, Bella failed to obtain the skill brought by a fusion, you must know that this skill is the only one, and only a fusion can have a chance to get it, and Bella obviously missed this opportunity......

"Husband, you see, I don't have any burden to transform now!" Bella said as she activated her realm, and in an instant, a layer of scale armor composed of physical energy covered Bella's body, making her incarnate into a dragon maiden state.

"It's so beautiful!" Seeing Bella's transformed state, Jiang Fei couldn't help but admire, after a period of fusion of the core of life, when Bella opened the realm again, her scale armor had turned dark green, this streamlined scale armor looked very beautiful, and at the same time, it also provided Bella with a more powerful defense!

Humanoids: Race Unknown!

Combat Strength Value: 9.5 million!

This is the result of Jiang Fei's observation of Bella through the goggles, because Bella is considered an artificial person, which is not recorded in the civilization that produced the goggles, so the race is determined to be unknown.

However, this is not the focus of Jiang Fei's attention, the point is that Bella's combat power at this time is actually as high as 9.5 million, and if she goes any further, she will approach the level of the Star Overlord!

You must know that Jiang Fei has been in the universe for so long, and it can be regarded as a series of adventures, but even so, before the second-stage fusion of the core of the will and the blackening of Jiang Fei's soul are one, Jiang Fei's strongest combat power is nothing more than that.

But what about Bella, she actually just completed a period of fusion, and she reached the peak of Jiang Fei's combat power before!

"Could it be that the basic energy core doesn't have skills, but the strength increase is more obvious?" Jiang Fei secretly guessed.

There are five types of energy cores, namely life, power, time, space, and will, and among these five, life and power are the basic types, and they are all directly elevating the physical power of the merger.

Time and space are advanced types, and they give the fused person the ability to intervene in parts of external things, or to intervene in space, or to exert influence on time.

The core of the will is the most special existence, it affects the will of all things, not only intelligent beings have thoughts, but also giant beasts or other creatures have will, and even a grain of sand, a rock, or even a planet has its own will.

It's just that dead things like planets have simpler wills and more persistence, and it is difficult for external forces to interfere with them.

Due to the lack of data on the situation after the fusion of the energy core, Jiang Fei had no way to judge at this time whether Bella had an abnormality, or whether the basic energy core should be like this after the fusion.

With incomprehension and temptation, Jiang Fei stayed with Bella for a while, and then he reflexively came to the center of the training ground, and at this time, the other girls also walked out of the biochemical cabin.

The four girls who have completed the original stage of fusion do not seem to have changed much, although there are also some improvements in strength, but it is not very obvious, for this, Jiang Fei is not surprised.

The energy core of the primitive stage is mainly improved to allow the fused person to comprehend his own domain, such as Jiang Fei's infinitely strong battle intent domain, and Bella's energy scale armor, but the domain takes time to comprehend, which cannot be completed in an instant, so after the fusion just now, the combat effectiveness of the girls will not be greatly improved.

After Jiang Fei and Bella completed the fusion of the primitive stage before, the reason why their combat power soared was because their strength skyrocketed relative to the strong people on the earth, at this time, the girls' combat power was close to one million, and when they arrived on the earth, they were all in the air every second, so this improvement was insignificant to them.

"You guys take a rest first, and then have a fusion after two hours!" Jiang Fei said to the girls around him, because the strength increase in the primitive stage was not very high, so there was no time for the girls to get used to it.

"0541, you start preparing. Jiang Fei chatted with the girls and told 0541 to start working.

Two hours later, everything was ready, and Nina and the other three girls stood in front of Jiang Fei, waiting for a period of fusion.

"Huh......" Jiang Fei took a deep breath, and then said to the girls: "Although Bella and I have successfully completed the fusion, there is still a lot of risk in this, have you all decided?"

"Don't worry, husband, we'll make it too!" said Sylvie.

"Yes, husband, my sisters will succeed!" Ariel also said on the side, because she only got a spatial core, so the follow-up fusion has nothing to do with her, and her main task now is to concentrate on comprehending her own domain power.

"Okay, since everyone is full of confidence, let's start, Ariel, you also have to hurry up and comprehend your own domain, although there is only one space core, but this is an advanced energy core after all, if you can comprehend a powerful domain, it may not be of little help to me!" Jiang Fei comforted Ariel who only got a space core by the way.

"Don't worry, husband, I won't hold everyone back!" said Ariel with a grimace at Jiang Fei.

"Okay!0541, ready to start!" Jiang Fei nodded.

When everything is ready, Mulan goes to the first one, and she will receive the initial fusion of the core of power.
