The spiritual energy is constantly injected into the body, and then it quickly nourishes the body.

If you practice in an ordinary environment without such consumption and pressure, Ye Yun would not be able to increase the strength of his body. But it is different in this Fire Dragon Cave. The heat is almost unstoppable. If the true qi shield is broken, even his strong body will not be able to support it.

While Ye Yun was crazy about absorbing spiritual energy, refining it, nourishing the body and replenishing the consumption of the true qi shield, he gritted his teeth and persevering. Even with the true qi shield, the rolling heat wave seemed to be used from the space, from the bottom of his heart, and pouring from all directions, which was irresistible.

Ye Yun knew in his heart that this was a very good time. If he could last here for a year or two, his body and true energy would definitely break through to an incredible level.

In fact, although the strong pressure brought by the heat of the Fire Dragon Cave can help disciples in the Qi Refining Realm practice, how can ordinary disciples have such a powerful body as Ye Yun to penetrate into this level? Normally, disciples below the fifth level of Qi Refining usually only practice in the stone chamber after entering the Fire Dragon Cave. Even in that environment, it is enough for them to not last long. Not to mention entering the depths of the Fire Dragon Cave.

Sweat came out from every part of Ye Yun's body, and it was burnt and dried as soon as it came out, and it was instantly evaporated. Hundreds of top-grade spirit stones were consumed rapidly, just two hours, almost half of it was consumed. This was an incredible absorption speed. If a disciple who had just started practicing at the first level of the Body Refining Realm and absorbed and refined all the consumed top-grade spirit stones, it was probably enough for him to reach the sixth level or even the seventh level of the Qi Refining Realm in one fell swoop.

However, even if so many spirit stones were consumed, the capacity of true qi that Ye Yun could store in his body had only increased slightly, almost negligible, and the tempering of his body was only slightly more, and it could not be clearly expressed.

Ye Yun can naturally persist, and he must persist. The time limit for the ninth-level mission Tianluo Concentrating Grass is very long, and it will last for a full month. Ye Yun is not in a hurry, not to mention that if he can break through to the second level of Qi Refining Realm here, it will be worth it even if the ninth-level mission is not completed.

Light and shadow flashed, and another pile of top-grade spirit stones appeared in front of you. The Little Star-Sucking Technique was running rapidly, and the continuous spiritual energy was injected into the body, quickly refining, absorbing, and tempering the body.

One hour, two hours, three hours, ten hours...

Ye Yun insisted so desperately, and there would be no more sweat in his body. If it weren't for the strong will, if someone else had come, I would have been unable to hold on and fell into a coma.

This is not an ordinary place, but the depths of the Fire Dragon Cave. If you fall to the ground in a coma, you will not take half a stick of incense and the incredible temperature will make people die quickly and become human.

Finally, when Ye Yun supported him for more than 30 hours, his whole body suddenly trembled violently, and then a faint soft light appeared on his body, and the true energy shield became thicker.

Ye Yun only felt the true energy in his body suddenly explode, and countless spiritual energy poured in and was quickly refined. The true energy began to flow wildly in his body like a torrent.

The true qi runs rapidly along the Ren and Du meridians. Every time it runs, the quality of the true qi becomes stronger. After full operation, the true qi, like a flood, does not stop as before, and begins to impact the eight extraordinary meridians.

Ye Yun was overjoyed. The impact on the eight extraordinary meridians was a sign of breaking through the second level of Qi Refining Zhoutian Realm. As long as the eight extraordinary meridians could be opened, the capacity of the true qi was equivalent to several times more, and the true qi in the Zhoutian Realm would be refined again and become extremely pure.

Generally, disciples are careful when they attack the Zhoutian realm, because the true qi cannot be as powerful and pure as Ye Yun. If you don’t grasp it well, the impact will come to an abrupt end.

However, Ye Yun was not worried. What he had always felt helpless before was that there was no sign of impact on the Zhoutian Realm, because the physical body and true qi were not able to perfectly reach the same level and complement each other.

Now, the true qi and the physical body finally reached the conditions to impact the Zhoutian realm at the same time. The violent true qi ran several times like a flood in the Ren and Du meridians, making the true qi extremely pure, and then began to impact the eight extraordinary meridians.

boom!

One, two, three...

The true energy is vast and unstoppable. In just a blink of an eye, five of the eight extraordinary meridians were opened.

Even though it had not been fully opened, Ye Yun had already felt the changes in his body. He held his breath and focused his mind, suppressing the joy in his heart.

After the true qi opened the five meridians, it did not stop there, nor did it weaken at all. It rushed all the way towards Articles 6, 7, and 8.

Unstoppable!

At this moment, Ye Yun completely understood the meaning of these four words, which was a completely unstoppable impact.

With one incense stick of kung fu, the eight extraordinary meridians were completely opened, and the true qi was circulating in every part of the body without any obstruction, completing the circulation of the cycle.

The second level of Qi Refining, Zhoutian Realm!

Ye Yun only felt a buzz in his mind, and then his whole body became refreshed. Even in this hot Fire Dragon Cave, he could feel the flow of true energy in his body, which was just a refreshing and cool feeling.

Ye Yun rose up, his eyes shone like lightning, and he rushed forward.

He laughed loudly, and the joyful laughter echoed in the cave, which lasted for a long time.

Ye Yun looked forward and saw that the passage ahead was about dozens of feet away. It had reached its end and had no way forward.

It can be seen that this channel is specially used for cultivation and has no other function.

No wonder the hole was touched as smooth as jade, just because disciples often come here to practice. But Ye Yun was very curious about what kind of cultivation skills needed to enter the end dozens of feet away?

It must be in the late stage of the Foundation Establishment Realm. Perhaps the cultivation of his two masters can easily stand at the end. What’s more, the Fire Dragon Cave has no help to them.

Ye Yun took a look reluctantly, then returned the same way, jumped out of the cave entrance, and landed on the big tree with a charred crown.

The true energy in his body was flowing several times more powerful and heavier, and became more pure. Now Ye Yun's strength is at least seven or eight times higher than when he entered the Fire Dragon Cave. If he faced Murong Wuhen now, he believed that he could easily defeat Murong Wuhen no matter what.

Ye Yun looked at the other two holes, then smiled slightly, rushed towards the hole directly in front of the way, and flew into the cave.

The cave is almost the same as the one before, and there are about two or three people walking side by side. On the top of the cave, there are pearls emitting soft light, illuminating the cave slightly.

The winding crystal-paved road leads to the front, and due to the corner problem, the end cannot be seen.

Ye Yun smiled slightly and walked forward with a meteor. The passage was not like the heat wave just now. He walked dozens of feet and did not feel any change in temperature. It seems that there is no real fire in this passage, and Ye Yun felt the breeze. It can be seen that there is another outlet in this passage, and both ends are connected.

Ye Yun walked quickly, but he did not let go of his vigilance. The true energy in his body rushed, gathering on the surface of the body to form protection. The true energy poured into his fists and could make a powerful punch at any time.

With just one stick of incense, Ye Yun walked about three or four miles away, but the cave had not been completed yet and there was no way to see the exit ahead.

Ye Yun frowned slightly. He was a little surprised that he had a space formation arranged. Otherwise, the peak of the Fire Dragon Cave would be only a radius of five or six miles. Could it be that the cave has been winding around the mountain? Otherwise, it would be impossible for him to walk three or four miles and not see the exit.

However, Ye Yun was not worried too much. After all, he could come out alive from the Huayun secret treasure. No matter how powerful the space magic array in the Fire Dragon Cave was, it was arranged by the Jindan realm monks, and it would not be much stronger than the ones in the tomb.

Ye Yun walked for an hour, and finally, he saw a light appearing in front of him, obviously that was the exit.

Ye Yun was happy in his heart, his feet accelerated, and in just a moment he arrived at the exit.

However, this is not an exit. What caught Ye Yun's eyes was a stone chamber covered by white soft light and a trace of psychedelic mist.

"It's not an exit." Ye Yun was stunned and said subconsciously.

"Who?"

Suddenly, a delicate voice came from the soft white light and entered his ears, so familiar.

Ye Yun was stunned and then was overjoyed: "Su Ling, is it you? I am Ye Yun."

"ah……"

The familiar voice suddenly screamed, and then Su Ling shouted: "Who asked you to come, go out quickly, go out quickly."

Ye Yun frowned slightly, and was extremely puzzled.

"You go out first, go out quickly, come in after a stick of incense." Su Ling's voice was filled with surprise and a little panic.

"Su Ling, what's wrong with you?"

Ye Yun did not notice the surprise in Su Ling's voice, but heard panic. He raised his eyebrows and shot in quickly, drilling into the psychedelic mist under the white soft light.

Just after breaking in less than three feet, Ye Yun saw a vague and slender figure ahead. He jumped over happily, landed beside Su Ling, and then raised his hand to land on her shoulder.

The tentacles are delicate and warm, and they are as smooth as silk!

Ye Yun was stunned, and Su Ling was also stunned.

"ah!"

Su Ling screamed, then turned around suddenly and said angrily: "Who asked you to come in? I'll say wait a moment, go out soon."

Ye Yun now understood why Su Ling didn't let him in, and this girl was not wearing any clothes.

Although Su Ling turned around, Ye Yun's hand that landed on her shoulder seemed to be stuck in the air, and he was stunned for a moment before he took it back.

"What are you doing? You don't even wear clothes." Ye Yun turned around, then flashed out the mist and returned to the entrance of the stone chamber.

Only rustling sounds were heard, and Su Ling was obviously dressed.

"You didn't listen if you said you wouldn't let you come." Su Ling's voice was filled with anger, and then she saw a light green body shot out from the fog and landed in front of Ye Yun.

"Hmph, Ye Yun, why did you sneak into the Fire Dragon Cave? You can actually find it here."
