Hao Yu didn't sit down to practice right away, he was going to take a good look at this underground space first. He tried to contact him, but when he didn't get a response, Hao Yu knew that he shouldn't be able to receive a signal from the outside world. Hao Yu tried to call the Dinghe seniors again, and soon got a response.

"Hmm, this place actually has such pure heaven and earth energy, and these crystals are all crystals of heaven and earth energy. ”

Ding He's words solved Hao Yu's doubts, he continued to walk to the depths of the cave, and found that there was an underground dark river here, and in the dark river, there was clear water, and in that water, Hao Yu also sensed a rich strange energy.

After nearly ten minutes of exploration, Hao Yu basically inspected every place in this underground cave, the area of this cave is not small, but there is only a small area, there is a crystalline body of the energy of heaven and earth, and in other areas, although Hao Yu can also sense a strange energy that is richer than the outside world, it is completely inferior to the energy of the area where the spar is located.

In a hidden corner, Hao Yu found a small altar, feeling the flow of energy around the altar, Hao Yu was sure that he was able to enter here before, it was completely the role of this altar, sure enough! He squatted in front of the altar and observed for a long time, and finally found that on the altar, every once in a while, there will be a little light up, the same as the light that Hao Yu had seen before in the outside world, after it was lit, there would be an illusory door, revealing from the point of light.

found the way out, Hao Yu finally relieved, he came to Guo Huitong not far away, found a place, released a futon, also sat down cross-legged, and practiced.

Time passed like this, minute by minute, in the process of Hao Yu and their practice, those spars in the cave, every once in a while, would become a little dim, and finally even some of the originally dull spars would directly lose their light and become an ordinary stone, shattered and fell to the ground.

At a certain time, Hao Yu, who was sitting cross-legged, suddenly shook his body, faintly, from his body, there was a soft snort, and when the energy aura shrouded the young man's body gradually dissipated, Hao Yu opened his eyes, he stopped doing exercises, and when he opened his eyes, he had a smile on his face.

"Very good! I have finally opened up the third vein in the Eight Veins of the Qi Sutra, so that my combat power will be greatly improved, and the mid-stage realm seems to be about to break through, okay! Muttering to himself, Hao Yu only got up and moved his body slightly, rested for a while, and then devoted himself to practicing again.

Suddenly, there was a loud bang, and Hao Yu woke up from his meditation, and he turned his head to look at the side! Guo Huitong spat blood from his mouth and lay on the ground, as if he had passed out.

"What's going on?"

Hao Yu immediately got up and stepped forward, picked up the girl from the ground, checked the girl's situation a little, and found that she was only slightly injured in her internal organs, and it was no big deal, Hao Yu was relieved, and then! He sat cross-legged behind the girl, with his hands behind Hui Tong's back, Hao Yu crossed his own internal breath and healed the girl.

It didn't take long for Guo Huitong to wake up: "Hao Yu, you don't have to waste your internal breath for me, I'm fine, it's just that when I was trying to break through the king-level barrier, I ran into trouble and was shocked by my internal breath." ”

After talking to Huitong for a while, Hao Yu understood that the girl was injured because she was in a hurry, so he combined his own situation and said some truth to Guo Huitong, asking her to consolidate her current realm first, and then find a chance to break through.

Facing Hao Yu, who was a little verbose, he stuck out his tongue, Guo Huitong smiled and said, "I know, don't worry, I won't take any more risks to break through to the king-level level." ”

Next, Guo Huitong asked Hao Yu a lot of information about the situation when breaking through the king-level level, and it can be seen that the girl really wants to break through to the king-level level as soon as possible.

Seeing that Hui Tong wanted to break through the realm so quickly, Hao Yu couldn't bear to persuade her to continue waiting, he thought about it, and suddenly a thought popped up, he hesitated again and again, and finally decided to say to the girl: "Hui Tong......! Since you are an evolutionary person, will it be very different from me in terms of realm breakthrough? If you follow my experience and method completely, it may not be appropriate. ”

After listening to Hao Yu's words, the girl was silent for a moment, and smiled at him: "You're right, I forgot about this, but how can an evolutionary person break through to the king-level level, I ...... I don't know, when I left my father's side, he hadn't become a king-level powerhouse yet. ”

Hao Yu thought of refining the soul Ding Ding core, but he didn't expect that before he could ask, the Ding core told him the method: "Evolution is actually the superposition of energy levels, so if the girl next to you wants to break through the realm, as long as her own energy is sufficient, she can naturally break through, and she can't follow your method, your method is only applicable to normal human beings." ”

Hao Yu immediately told Hui Tong what Dinghe said, using the information he found on the Internet as an excuse.

"I see, that is to say, my current internal breath energy is not enough to support me to break through to the king level? ”

Guo Huitong, who knew the way to break through the problem in his own realm, returned to the innocent and natural smile of the past.

Although they are eating dry food that has no taste, when two people who are close to each other sit together, no matter what they eat, it is a delicacy in the world, Hao Yu and Guo Huitong, this is the case, they chatted beautifully, and after filling their stomachs, they chatted enthusiastically for a while, and when they felt that they had rested enough, they entered the state of practice again.

When Hao Yu was quietly practicing in the underground cave to improve his combat strength, he didn't know that the outside world had already set off a big wave because of him, especially the Eternal Group, because he had taken the Crystal Soul Tower into his hands, and had already mobilized a large number of people to move around, just to catch him, this order to arrest him was directly issued by Tianying, and the main consul was Feng Yan, a young man who had a special relationship with Hao Yu.

In just a few days, there are a lot of outsiders in the United States, most of them are the support troops sent by the Eternal Group, and there are many alien creatures who have stepped into the American continent, as for their targets, I heard that it is also Hao Yu, but if anyone in the know, they will know that there is another target on the side of the alien creatures, that is, the girl next to Hao Yu.

Thinking of the instructions given to him by Tianming before leaving, Feng Yan's eyes became a little colder, and he said to himself in his heart: "Hao Yu! this time, I see how you can escape......? Hmph, cripple you, it's not against the old guy's orders......"
