"Poof" the sound of a heavy object falling into the water, I saw Zhang Peng curled up like a roasted lobster, and fell straight into the pool, splashing a circle of crystal waves.

Luckily, just when he thought he was about to die from the explosion of those strange light words. The extreme pain that can blow the mind out only lasted for a short blink of an eye, and then disappeared without a trace. This made Zhang Peng angry and felt that if the time was longer, he didn't know if he would be blown up, so he fell in a daze.

And now although the great pain has disappeared, his head is buzzing at the moment, and he has no strength in his whole body, so he can only soak in the pool of water weakly.

After a meal, Zhang Peng felt slightly better. Finally regaining a little strength, he was ready to immediately climb out of the pool to meditate and adjust.

But before he could act, he suddenly felt cold, which made him feel a little inexplicable. You must know that since he practiced the sixth layer, he has not been afraid of cold and heat. Not to mention ordinary mountain spring water, even ice water, he didn't feel any discomfort.

At the moment when Zhang Peng was stunned, the cold meaning became stronger and stronger, and it faintly emanated from his body, which made him immediately startled. In the information he knew, although the water of the spiritual spring was no better than ordinary water, it would not be so cold and piercing, and it was unlikely that he would have this feeling.

This strange phenomenon made him immediately lean towards the edge of the waterhole, and although the waterhole was only three feet deep, he had not yet taken two steps towards the edge of the waterhole. The cold meaning in his body spread out in his body like a snow-capped mountain collapsing. In just an instant, Zhang Peng felt that his limbs were cold, and his whole body seemed to be frozen, and then he fell down again like a wooden stake.

But what struck him was that the cold didn't last long, and his limbs began to feel warm again.

"Could this similar feeling be" A strange thought suddenly flashed in Zhang Peng's mind, and then he couldn't care about anything else, taking advantage of the heat flow to get warmer and warmer, and hurriedly rushed towards the waterhole.

"Ah" A miserable scream came out of Zhang Peng's mouth, and as soon as he was about to climb out of the pool, the hot current exploded, instantly turning into a strange hot force that flowed all over his body. He suddenly felt like a pheasant thrown on the fire grill, and the whole thing became red and unbearably hot.

Just when he felt that his whole body was about to be blown apart by the heat, the heat came and went as fast as the cold in front of him. It was just a few breaths, but it suddenly turned into a sharp pain like a prick of thousands of steel needles and a strange itch like thousands of ants crawling over.

"Ahh At this time, Zhang Peng's face completely turned snow-white, almost not a trace of blood, and beads of sweat the size of soybeans continued to drip down his cheeks to the ground, showing the inhuman torture he had just suffered.

And after the time of the meal, Zhang Peng, who seemed to have recovered a lot, felt the surging mana all over his body, but his whole cheek couldn't help revealing a sincere excitement, as if the person who was tortured just now was not him:

"Haha, I really didn't expect this spiritual spring to have the effect of easy tendon and marrow washing, it seems that the sky will not kill me. ”

After a few hours, I felt that I had fully recovered both my energy and strength. Zhang Peng slowly walked to the edge of the pool, staring at the aura of the pool with a hesitant expression.

At this time, he was engaged in a fierce struggle in his heart, should it be better to go down and directly pour his body from the spiritual spring to wash the marrow? Or should he soak in the spiritual spring like before, and then slowly wash the marrow from the spiritual spring?

However, this question didn't seem to bother Zhang Peng for long, just a cup of tea, and he made a decision. I saw that his expression froze, and he took off all his clothes in just a few breaths, and then walked into the pool with his whole body. The knees were slightly bent, and as soon as the whole person squatted, his body was all immersed in the spiritual spring.

The reason why Zhang Peng chose the former so decisively was that he thought that the effect of slowly washing the marrow after being attached to the spiritual spring was definitely not as good as the effect of soaking in spiritual water. You must know that in the world of cultivating immortals, all elixirs with easy tendons and marrow washing are sky-high, and they are still in the state of being rich and unsought-forgiving.

And a spiritual pool like this that can have easy tendons and marrow washing is estimated to be impossible to find in the immortal cultivation world with lanterns. Even if there is, that's not what he Zhang Peng can think.

The second reason is also the real reason that prompted him to choose the former, although it is extremely painful for him, but his qualifications are extremely poor, if he does not make good use of the spiritual pool in front of him, it is estimated that he can only stay in the foundation building period in this life.

And building a foundation is only the beginning of cultivation, and there is no comparison with the avenue you are pursuing. If he is stopped by this little pain, then what is he going to do to fight for further progress on the avenue?

A quarter of an hour later, the cold feeling of the limbs that had been felt before had returned, only this time it was much stronger than the last. But fortunately, Zhang Peng came prepared this time, and this abnormality did not make him have any abnormality.

However, after just exhaling and breathing, the cold feeling was more than ten times better than before, even if Zhang Peng had expected it in his heart, he suddenly roared.

Then the cold feeling turned into that scorching feeling again, but the power was also about ten times stronger than before, and the strong contrast between one cold and one hot immediately made Zhang Peng howl unbearably, but for some reason others were just tossing in the waterhole, without the slightest sign of going ashore

After a day and a night, Zhang Peng slowly climbed onto the waterhole with his whole body, and then meditated on the spot without any image. At this time, his face was tired all over, but he couldn't hide the joy that was revealed.

In this day and night, his harvest was unimaginable. Although five or six hours before arriving at the pool, due to the intense muscle-washing effect of the pool water on the body, the severe pain that seemed to be ten times more painful than the corpse of the five horses was simply beyond the imagination of outsiders. If Zhang Peng hadn't fainted directly at the beginning, even he didn't know if he would have committed suicide in order to get out of pain.

Then, after a few hours, Zhang Peng woke up groggily, and at this time he found that the effect of the pool water on his body had become much smaller, and the severe pain and itching had become within his acceptable range.

In this way, he concentrated on his whole body in the pool, until a day and a night later, he found that the pool water no longer had any effect on him, so he stepped out of the pool with satisfaction and began to meditate and adjust his mana.

At this time, he was looking at his dantian with an excited face, and at the dantian, he found that his original gaseous mana, except for a small piece in the center, had all been converted into an extremely dense liquid true element, and his own exercises had thus reached the peak of the twelfth layer, and he was only one foot away from breaking through the qi training period and entering the early stage of foundation building. It can be regarded as a real member of the immortal cultivation world.

Although he is only one step away from stepping into the foundation building period, Zhang Peng also knows that this matter is urgent, at least now he has no exercises above the foundation building period, and more importantly, he still has a lot of foreign things stuffed in his mind, which makes his brain feel like being flooded, which is extremely uncomfortable.

In this way, Zhang Peng sat hovering in place, carefully combing the things that came from the golden pages, and it was not until two days later that he showed a tired expression of slightly excitement.

After two days and two nights of sleepless combing, the feeling of swelling in his brain at this time has completely disappeared, and he finally figured out the content of the golden light words:

"Thunder Night True Technique" is the name of the exercises recorded in these light characters. The rest is a detailed record of the full set of Dharma decisions from the first to the fifteenth layer, without the slightest defect, according to the exercises, you can cultivate to the legendary early stage of refining without any problems. However, at the end of this exercise, there is a clear reminder that those who practice this exercise must have the surname of the Thunder Fire Spirit Root before they can practice. That's all the details that these photons bring.

After reading this information, Zhang Peng was slightly stunned, and then hesitated a little. I didn't expect that when I was lacking exercises, I got a copy by chance. However, he had never heard of the Thunder Fire Spirit Root mentioned in the exercises. If you think it's definitely not a pseudo-spiritual root like the Four Spirit Roots, I don't know if you can cultivate?

Thinking of this, Zhang Peng couldn't help but fall into deep contemplation again, and after a full cup of tea, he sighed again and muttered to himself:

"Whether you can cultivate or not is a matter after the foundation is built, and now I haven't even passed the foundation building level, so I'm worried about this here, it's really a bit unfounded. After a few wry laughs, Zhang Peng really didn't seem to plan to continue to dwell on this issue. Then I adjusted my mentality and meditated and breathed. (To be continued)
