Recently, there is no mobile phone data, and there is no network in the dormitory, so it is almost early in the morning after writing and proofreading the manuscript every day, so it can only be uploaded when I go to work the next day.

There will only be no update at 11 o'clock in the future, so please don't wait for the update, I will upload it the next morning. From the 29th to the 31st, I want to go back to my hometown once, during this period, there is no network in my hometown, if you can't update it, please understand, I will update my surname this weekend, September 1st. By the way, I would like to thank the prodigal son, sharp arrows piercing the sky, yunfeiyang7 and other book friends for their tips and support. With your support, I will work harder to write each chapter.

Three days later, Zhang Peng, who felt that he had adjusted to the best state of mind and mood, prayed to the heavens with devotion and sat down cross-legged solemnly, and then patted the storage bag, and a beautiful black wooden box appeared in his hand in a flash.

Zhang Peng took the wooden box and looked at it carefully for a while, and finally after staring at it, he slowly opened it, only to see a cyan jade bottle lying quietly in the wooden box.

Zhang Peng grabbed it out without hesitation, and then pinched it with one hand, and between the slight movements of his lips, a layer of soft white light flashed between his fingers. In just a few breaths, his entire spell-casting palm was completely shrouded in a layer of white light. Seeing this, Zhang Peng smiled slightly and snorted:

"On"

The palm of the hand that flashed with white light gently brushed the mouth of the jade bottle, and I saw that the moment the bottle mouth brushed the palm of the hand, a layer of the same white light flashed, revealing the lid of the jade bottle itself

Then Zhang Peng gently opened the cap of the bottle, and poured out a light blue pill with a tangy medicinal fragrance into the palm of his other hand. I saw that after he picked up the pill and looked at it twice, he put it in his mouth without hesitation, and after a grunt, he swallowed it in his stomach.

Then he closed his eyes and waited for the drug to kick in. And the reason why he was so solemn was that the pill was not any other pill, it was the Zhuji Dan that he got from Senior Sister Ling and Senior Brother Zhang, who ambushed him. Just today, he was ready to rely on the two Tsukidans in his hand to start breaking through the bottleneck of the foundation building period.

After an hour passed, the power of Tsukidan's medicine began to kick in. Just in an instant, Zhang Peng's face changed, and he covered his stomach with his hands and groaned. At this time, he felt as if there was a dragon in his dantian that was turning over the river and the sea, completely stirring up the liquid true yuan in his dantian, and the huge pain caused by it was no less than the easy tendon washing marrow of Lingquan.

In addition to the severe pain, Zhang Peng couldn't help but think angrily, why no one had told him when he received the Tsukidan, and there was such pain in taking the Tsukidan.

But now he could only scold angrily twice in his heart, and this sharp pain lasted for nearly half a cup of tea before disappearing without a trace. This made Zhang Peng, who had just recovered his breath, stunned, but before he could think about anything more, he suddenly found that it was all hot, and then a pain that penetrated deep into the bone marrow and an itch like thousands of ants crawling away opened up.

After a full meal, the sharp pain and itching disappeared without a trace. At this time, Zhang Peng was already sweating profusely, and his clothes were all soaked, wasn't this the same as Lingquan's easy tendon marrow? Feeling the sharp pain and itching just now, Zhang Peng thought strangely in his heart.

However, he didn't care too much about this, what he cared about was that the small amount of gaseous mana in the original dantian had already been converted into liquid true element. He felt that he had completely touched the threshold of the foundation building period, and believed that as long as he meditated and absorbed and refined the residual medicinal power of the foundation building pill, he would be able to successfully break through the bottleneck of the foundation building period and truly enter the foundation building period.

However, Zhang Peng didn't intend to do this, since he completed the Yi Jin Purification in this spirit pool, the aura of the entire spirit pool began to gradually weaken significantly. And because of the gray substance discharged by his marrow, the whole waterhole emitted a faint fishy smell. Although after so many days of spiritual energy purification, the fishy smell has not weakened much.

According to the current situation, Zhang Peng estimated that this spiritual pool would stop spewing spiritual energy in a few days. I don't know why this happened, but it's definitely not a good thing for him. Therefore, he decided to search carefully as soon as he broke through the foundation building period to see if there was an exit to the outside world.

After swallowing the only remaining Zhuji Pill in the jade bottle, Zhang Peng closed his eyes and began to refine the pill with his heart. A short hour passed again, and the medicinal power of Tsukidan melted again. After experiencing the same severe pain and itchy torture, Zhang Peng finally transformed the last bit of gaseous mana in the dantian into a liquid true element.

With a silent rumbling sound, Zhang Peng felt as if a sledgehammer had been smashed open in his mind. Then things ten feet away appeared in his mind, and he could detect a distance of three feet at most, which means that his divine thoughts at this time instantly increased more than three times compared to before.

At this time, the situation is not only that his divine thoughts have increased several times, but also that the dantian has expanded by nearly one-tenth compared to before, with a rushing surging mana flowing through the meridians of the whole body, and then honestly returning to the dantian, Zhang Peng finally entered the foundation building period as he wished.

But before he could be happy, he felt a burning heat. This made him startled, and after quickly looking inside, he realized that he had unconsciously absorbed too much spiritual power when he was soaking and washing the marrow in the spiritual pool.

Because it was not refined in time, it was all deposited in his body. Originally, this spiritual power would dissipate by itself after a while. However, Zhang Peng was in a hurry to build a foundation, and after he took two Zhuji Dan without stopping, this hidden spiritual power was instantly stimulated again.

And because of the difference between the medicinal power of Tsukidan and the spiritual power of the spiritual pool itself, the two are mutually exclusive, so he is now in a very dangerous stage. If he can't refine these two spiritual powers in time, I believe that he will soon be violently rejected by the two different spiritual powers, and finally end up dying violently.

Although he knew what was going on, Zhang Peng was not happy at all. Because of him, at this time, except for the thunder secret obtained from the mysterious golden page, he thought that there were any exercises above the foundation building period.

And this seems to be a sword technique, and it is also clearly stated that you must have a thunder fire spirit root before you can practice. What kind of thunder fire spirit root is that, what if you can't cultivate yourself?

Thinking of this, Zhang Peng began to be a little impatient, and the two spiritual powers in his body seemed to be more intense because of his impatience. In just a dozen breaths, his entire body began to tremble slightly.

"No, I have to be calm, otherwise I didn't expect that I would definitely explode and die first" Zhang Peng kept admonishing himself in his heart and forced himself to calm down.

Although his state of mind had begun to forcibly calm down, the hedge between the two spiritual powers showed no sign of slowing down. At this time, his whole skin was already crimson, just like the previous marrow washing and tendons. And the body that was originally cross-kneeled like Mount Tai also began to be unstable because of the violent tremors.

"We can't go on like this, or we're going to die today. Feeling the strong strangeness coming from his body, he had no choice but to make up his mind and prepare to treat a dead horse as a living horse.

After quickly recalling the magic of Lei Xiao's true formula, and feeling that there was no doubt, Zhang Peng closed his eyes and carefully began to refine his exercises in accordance with the practice mantra of Lei Xiao's true formula.

There are a total of fifteen layers of this Thunder Sky True Technique, the first nine layers are for the cultivation of monks in the Qi cultivation period, foundation building period and Jindan stage, and the tenth to fifteenth layers are for monks in the Yuan Infant stage and the Transformation God stage. According to the exercises, every time you cultivate this exercise to three levels, you can use a unique supernatural power attached to the exercise.

After the first three layers of cultivation are successful, they can use no magic weapons, and they can instantly release a flame giant blade with one hand, which is powerful enough to compete with ordinary high-grade magic weapons.

After the cultivation of the fourth to sixth layers is successful, you can instantly release the body protection fire shield and the six-armor shield soldier. Its Protective Fire Shield is about a little more defensive than the average intermediary defense spell, while the Rokkaku Shield can transform everything into two undead golems with one-third of its own power.

As for the supernatural power after the last three layers of the early stage, it is the magic that can cast a thousand sword duel and the legendary thunder and fire escape method. However, the premise of casting these two spells is that you must have at least a set of at least twelve magic weapons of the flying sword type, and of course, you can use throwing knives if you like to.

After cultivation, when this magical power is against the enemy, the flying sword body will evolve into a strange sword array, with the help of the power of the sword array, each flying sword can instantly transform into three sword shadows that are exactly the same as the original flying sword. Although the initial power can only reach one-tenth of the original flying sword, with the improvement of the level of the sword technique, after finally reaching the ninth layer, it will have one-half of the power of the original flying sword.

What's even more troublesome is that before this magical power stops, its sword shadow will never stop transfiguring to attack the enemy. As for the Thunder Fire Escape Rule, it is required that a pair of Thunder Shadow Flame Wings must be refined in accordance with the materials required by the exercises.

As for the supernatural powers after the Yuan Infant Period, due to Zhang Peng's limited realm, his exercises automatically covered up his related supernatural powers. Zhang Peng is no stranger to this situation, and as far as he knows, there is a special introduction to it.

When many exercises and magical powers were taught by their predecessors in the world of cultivating immortals, they were worried that future generations would be too ambitious and cultivate beyond their own realm, which led to the madness and failure. As long as his own exercise realm is not enough, the subsequent related exercises will be automatically hidden. With Zhang Peng's current realm, he can naturally only see the magic powers of the Jindan period
