An hour later, Yun Zhongge picked three exercises for Yang Hui, Lin Dong, and Lin Yu, which were attack, body and defense. If they cooperate well with each other in this way, their strength will increase a lot. Even skipping the level is not impossible.

Mu Xue also picked two exercises, one is the Aoba Sword Technique, which is an offensive exercise, and the other is the Dance of the Wind, which is the body method. These two exercises complement each other, and they are also quite suitable for Mu Xue.

Yun Zhongge already has Nine Dragons Xuangong, and although his attacks are strong, he is a little lacking in body skills. As for the ethereal star formula, with his current understanding, he can't understand it thoroughly, and he has only understood the first layer of this ethereal star formula. Even so, it is also a powerful combat skill like this Nine Dragons Xuangong.

Yun Zhongge believes that if he deeply comprehends this ethereal star trick, he will definitely get the secret technique he wants. But now, maybe his qualifications are not high enough, and every time he practices alone late at night, he feels more and more difficult, let alone comprehending the secret techniques of the body.

He found a secret technique called "Wind Execution" here, which was somewhat similar to Mu Xue's Wind Dance. The difference is that the Dance of the Wind is generally only suitable for women, while this Wind Dance is suitable for men.

Now that they have the exercises, and several of them are already martial artists, I believe that it won't be long before the four of Yang Hui will have good strength, even if they walk alone in this Beiyuan City, they will have the power to protect themselves, and it is not difficult to survive.

After the two of them packed the exercises they wanted to take, they left the library.

"I'll go to that thing in my yard, you wait for me." Mu Xue looked at the song in the clouds and said.

"I'll come with you." Yun Zhongge nodded, because she was a little worried that Mu Xue would act alone, so she went to the courtyard where she used to live with her.

The courtyard where Mu Xue used to live is in the corner of this Mu family, and it is much smaller than the courtyard elsewhere, and it looks relatively dilapidated.

"You wait for me, I'll go in and that thing will come out." Mu Xue said and pushed open the door and walked in.

Yun Zhongge didn't go in, standing in this small courtyard, looking at the lush trees, as well as the flowers and plants that had not been taken care of for a long time, he couldn't see that this Mu Xue was still a woman who loved flowers.

After Mu Xue entered, she came out after a while.

"Let's go." Mu Xue's eyes were slightly red, obviously she had cried just now.

"You're alright, if you want to stay here a little longer, I can stay here with you a little longer." Yun Zhongge said softly.

"It's fine." Mu Xue smiled lightly and looked at Yun Zhongge, "I just remembered my parents, so I'm a little sad." ”

"Let's get out of here first, and try to have a good day." Mu Xue smiled, deliberately trying to make herself happy. But in the depths of those eyes, there is still a heart-wrenching sadness.

After the two of them left here, the next time was to hunt mutant zombies. Maybe it's Mu Xue, the luck of the two of them is very good today.

Until dusk, Yun Zhongge alone hunted more than fifty mutated zombies, as well as six or seven first-level demonic beasts.

The Rage Crystals collected in one day today alone are the sum of the previous two days. Yun Zhongge looked at the nearly sixty furious crystals, and there were other thoughts in his heart. Originally, he planned to accumulate some berserk crystals in two more days before breaking through the Kaiyuan Realm, but now he has reached so much at once.

He just didn't give them today, let them familiarize themselves with the exercises tomorrow, practice the exercises, and wait until they broke through to the Kaiyuan Realm, and then hit some more berserk crystals for them to use.

Mu Xue naturally didn't have any opinions, and after returning to the Black Oil Mountain Villa, Yun Zhongge told them what he thought.

Yang Hui and the others also agreed. After that, Yun Zhongge handed them the exercises they found for the three of them, and asked them to start learning the above exercises now, and strive to practice them as soon as possible, and when the time comes, their strength will improve, and with these exercises, it is not impossible to go to Beiyuan City to hunt those mutated zombies.

Yun Zhongge simply ate something and went back to his bedroom.

He took out those berserk crystals, plus the ones he had collected before, there were more than eighty of them, which was enough to break through the Kaiyuan Realm.

He came to an open space in the bedroom, sat down cross-legged, and then put those berserk spars beside him, first closed his eyes and adjusted his state, then grabbed a few berserk spars and absorbed them, ready to start breaking through the Kaiyuan Realm.

Now he absorbed those berserk crystals by no longer bleeding from his fingers, but with a trace of vitality in his body that he had taught on the radio. That's why he was able to absorb several berserk crystals at once.

When the energy of those furious spars flowed into Yun Zhongge's body, a sharp pain came in an instant, and Yun Zhongge roared in pain, the green tendons on his forehead burst out, and beads of sweat the size of beans quickly appeared.

Yun Zhongge endured the severe pain in his body, and according to the mind method of the Ethereal Star Jue, he gradually attracted those energies to swim in his body. Everywhere he walked, his meridians widened a little.

The so-called Kaiyuan is to open up the Yuan Sea in the dantian acupoint in the body, which is condensed by the qi of those true yuan.

It seems simple, but it is extremely difficult to open the Yuan Sea, and if you are not careful, you will end up with a burst of meridians and acupuncture points. Therefore, Yun Zhongge's nerves have been tense, and he carefully guides those violent energy flows around his body at all times, and then gathers the dantian and opens up the Yuan Sea.

With a bang, there was a muffled sound from the spiritual world, and the violent energy flow rushed directly into the dantian acupoint of Yunzhongge, and the originally silent dantian acupoint became boiling all of a sudden, and the wisps of energy flow instantly turned into a vortex in his dantian acupoint, turning wildly.

This rotation didn't matter, it attracted more energy streams into his dantian acupoint, and in just a moment, he felt that the position of the dantian acupoint had a feeling of swelling. Yun Zhongge was shocked in his heart, and he didn't have time to think about it, so he hurriedly ran the Ethereal Star Technique, guiding those violent energies according to his mental method.

Time passed little by little, and it was already two hours in the blink of an eye.

Yun Zhongge opened his eyes and breathed a long sigh of relief, he felt the surging power in his body, and his expression was also happy. It took him sixty furious crystals to completely stabilize the Yuan Sea, and this opening up was to open up a Yuan Sea five miles in size. And the martial artists who have just entered the Kaiyuan Realm have opened up the Yuan Sea that is only one mile in size, and every time the strength is improved, the Yuan Sea increases by one mile.

The song in the clouds entered the Kaiyuan Realm as the Yuanhai of the Five Miles, but it was equivalent to the martial artist of the Kaiyuan Fivefold Realm. But his realm was indeed the first realm of Kaiyuan, which shocked him.

After another simple pranayama, Yun Zhongge got up and went to the bathroom to take a shower, changed into clean clothes, and walked to the balcony on the fourth floor.

Although it was close to night, he still wanted to go up and take a look at the starry sky.
