The other four generals didn't know where they had gone. In the entire empty hall, there were only the head coach Wu Hai and their four disciples.

"The feeding ceremony is over," Wu Hai said, "and the mother nucleus has returned to normal. ”

"Really, Master?" Li Wenxin glanced in the direction of the mother nucleus.

"Well," Wu Hai stroked his beard, "what did the impact and pressure from before make you feel? It's very uncomfortable, isn't it?"

Xue Mengyi nodded, her small mouth pursed slightly, and an unhappy expression appeared on her face, but she immediately changed back.

"That's a side effect of the Twelve Spirit Generals' secret method, the Multiple Spirit Vortex," Wu Hai said, "I could have completely blocked it, but I didn't. I've been bored in this Spirit Core Valley for too long, and I don't know much about your cultivation and physical condition, so I want to use it to test your endurance and defense. ”

"I'm very happy. Not only endurance and defense, but also the physical qualities of several of you are among the top among spirit masters of the same level and attributes. This is true even if you don't count the factors of the micronucleus. ”

"Thank you...... Thank you for the compliment. Ye Hengyuan was a little embarrassed and lowered his head.

"Don't be so restrained, Xiaoyuan. ”

Wu Hai smiled and bared his teeth. His teeth were still intact, not a few had been lost, and they were still as smooth as jade.

"You're kind of like my little grandson. He's a few years younger than you, and he's too shy to talk much. ”

Ye Hengyuan's face turned red involuntarily. Xue Mengyi and Lei Xi both covered their mouths and laughed secretly.

"Alright," Wu Hai stretched out his hand and motioned for the two girls not to laugh, "You all come with me." You haven't seen the nucleus yet. Let me take a look at you. Then I'll tell you what to do. ”

"Yes, Boss. ”

The four disciples bowed again, automatically lined up, followed behind Wu Hai, and slowly walked towards the mother core. Wu Hai's pace is slow, but it is also steady, not like the pace of an old man. The four disciples didn't hear the slightest sound of footsteps, and they couldn't even feel the slightest fluctuation of spiritual power from him.

Wu Hai slowly walked between the mother nuclei, stopping in front of an unclear sign of the mother nucleus and the twelve daughter nuclei on the floor. The logo is blurry, even a lot of wear, and it is not colored, and it looks like a mess of dents. As his feet landed in front of the dents, a pillar of transparent light as thick as the trunk of a century-old tree slowly shot out from the center of the mother nucleus, all the way to the ceiling.

The four disciples automatically separated and lined up behind Wu Hai. Twelve air masses of different colors were connected in a group, arranged in a slender straight line, like a seaweed, slowly rising from the bottom of the pillar of light.

"These twelve kinds of air masses represent twelve spiritual power elements with different attributes," Wu Hai's voice was a little crisper than before, "It is the energy crystallization in the mother nucleus." All spiritual power comes from these energy crystals. The entire Cangling Continent was formed under the action of these energy crystals. They are only one ten-thousandth, or even one hundred-thousandth, of the countless energy crystals inside the parent nucleus. As for the amount of spiritual power contained in the mother nucleus, I can't detect it. ”

The four disciples raised their heads at the same time, looking up at the twelve different air masses. As if the water snake-like chain of air masses had come to life, it circled up and down on the top of the pillar of light. In their eyes, different air masses emitted different lights, and the light that represented the spiritual power attribute they possessed was even more dazzling. Four micro-spirit cores came out of their backs at the same time. Four bright white dots of light flickered in their centers.

"The volume and mass of the mother nucleus are incomparably huge," Wu Hai said, "According to the calculations of many generations of Twelve Spirit Commanders, including me, its diameter is almost equal to the height of the highest mountain on the Cangling Continent, accounting for more than two-thirds of the depth that can be explored under the Cangling Continent at present. What we can see here with the naked eye now is only a tiny, tiny part of it. ”

The four disciples were all dumbfounded. Not to mention Ye Hengyuan, even Xue Mengyi and Li Wenxin couldn't say a word. This sentence is completely beyond their cognition.

Wu Hai stretched out his right index finger and pointed to the chain of air masses that were "floating" above the pillar of light. A silver beam thinner than his withered fingers shot out of his fingertips and toward the chain of air masses. The beam of light hit the center of the chain of air masses, and then split into four beams, reflecting back from the four directions, shooting at the chests of the four disciples.

"Don't be nervous. Don't resist or dodge it. It won't hurt you. This is to establish a direct connection between you and the mother nucleus. ”

A spherical ball of light mixed with twelve colors appeared on each of the chests of the four people. They shine like four little suns.

Time passed second after second. The four spherical clusters of light faded away. Wu Hai turned around and faced the four disciples.

"Good. Now, listen to me, and stand in turn before the pattern at my feet. Keeps the micro-nucleus spinning. Ashin, you come first. ”

"Yes, Master. ”

Wu Hai took a step back to the side. Li Wenxin stepped forward in response and stood where Wu Hai was originally standing. The micro-spirit nucleus, a mixture of silver and gray, slowly rotated, and a small white point of light in the center flickered.

Wu Hai raised his right hand again, stretched his hand towards the pillar of light released by the mother core, and then raised his hand to point at Li Wenxin.

The spirit core pattern in front of Li Wenxin's body instantly became colored, and the lines on it could also be seen. A beam of colored light, a circle wider than his body, suddenly emerged from the floor beneath his feet, enveloping his entire body.

And in the faint pillar of light released by the mother nucleus, a spherical phantom that was both real and illusory appeared. It is a perfectly circular sphere with at least three layers from the outside, the outermost layer is almost completely transparent, the middle layer is a chain of twelve colors of air mass, and the innermost layer is a mixture of pale yellow and milky white, like milk.

"This is the epitome of the parent nucleus. Wu Hai said lightly, "Don't talk yet." You'll see in a moment what this is all about. ”

A beam of colored light mixed with twelve colors shot out from the center of the spherical phantom and hit the periphery of the pillar of light where Li Wenxin was. It moved slowly around the perimeter of the pillar of light, changing color as it moved, sometimes dark and sometimes light, as if scanning something.

Ye Hengyuan stared intently at the colored beam. He felt that the beam of light seemed to be calling him, and the dragon pattern Fang Tian Halberd in his body seemed to be called as well, emitting bursts of powerful energy fluctuations, impacting the spiritual veins in his body, as if it was about to rush out of his body.

After a few minutes, the beam stopped scanning and turned into a white streamer with no attributes, merging into the pillar of light where Li Wenxin was. The pillar of light faded away. Li Wenxin's figure reappeared.

"Ashin," Wu Hai's tone became a little more serious, "Your cultivation has been a little lax these days. I know it's probably because you have so much to convey and deal with. However, your current understanding and comprehension of spatial energy is not deep enough. With your current spiritual cultivation, you shouldn't only have this level of comprehension. Although you have made great progress in the use of energy, if you do not improve your comprehension, your combat effectiveness will still be limited to a certain extent. ”

"I'm sorry, Master," Li Wenxin lowered his head and stroked his chest with his right hand, "I'm indeed a little lax in these points. ”

"Well," Wu Hai stroked his beard, "the mother nucleus just helped you straighten out the brain tissue in your brain, which will help improve your comprehension." Go back. Little Lei Xi, you come. ”

Ye Hengyuan almost screamed. He stretched out two fingers and pinched his thighs so hard that he didn't let himself scream. He remembered that the classroom in the academy had taught that the brain was the most delicate and complex organ of human beings, and it was difficult for even the most top-level spiritual masters specializing in medicine to effectively treat the human brain. However, the power of the mother nucleus is able to comb through the human brain tissue......

Li Wenxin took a few steps back and stood beside the other three. His face was not very good-looking, his eyebrows were furrowed, one eye was closed, the other was squinted, and his right hand kept rubbing his temples, and he knew that he had a headache at a glance. No one said anything.

Lei Xi took a few steps forward and stood in front of the spirit core pattern. Wu Hai also beckoned to the mother nucleus and pointed at her. The same pillar of light enveloped her body. The same colored beam falls on top of the beam of light and begins to scan.

This time the scan took a little more than the last time, about two minutes more. By the time the pillar of light faded away, it had turned completely purple-red.

Lei Xi's body reappeared in everyone's sight. She closed her eyes, stood on tiptoe, her arms drooping naturally, but her palms were raised upward, as if she was dancing. Fuchsia thunderbolts crackled around her body. A purple phoenix pattern completely condensed by spiritual power loomed behind her.

"Well," Wu Hai showed a satisfied expression on his face, "Renze's eyes are really not bad. Little Lei Xi, your energy control talent is very high in your family. But for the heirs of the Wrathful Thunder General, this was not enough. Although the lightning attribute is not the most difficult energy attribute to control, it is the energy attribute that is the easiest to lose and cause unnecessary loss. Renze and I have both told Long Yao that in your cultivation and battles, you often cause unnecessary energy loss in order to pursue attack power and lethality. It's not good. Your attack power is strong enough, but the loss of your own energy is also very large. In battle, any extra attrition can result in the loss of the entire game, or even your life. ”

Ye Hengyuan couldn't help but bow his head—because he couldn't help but open his mouth. With Lei Xi's energy * control ability, it can still cause "very large losses"?

"The mother nucleus just helped you sort out the spiritual veins within a *," Wu Hai said with satisfaction, "It can help you improve the problem of energy loss and loss in your body." ”

'Thank you, manager. ”

Lei Xi bowed respectfully and retreated. There was a slight smile on the corner of her mouth, her long seaweed-like shawl hair seemed to grow a little longer, and her white jade-like skin seemed to become more delicate.

"Little Mengyi, it's your turn. Wu Hai set his eyes on Xue Mengyi
