The secret book is only a dozen pages, with dense small words on it and half-verbal writing. It is not difficult to understand. It records a trick to restrain true qi.

Zhang Feng studied it several times, tried to practice it, and his breath immediately restrained. At first glance, he seemed to be an ordinary person, but the only difference was that he had a good figure, a good appearance, and a healthy appearance.

At the same time, a new skill immediately appeared on the attribute panel: 1 point of the primary Qi-retention technique.

"good!"

Zhang Feng didn't care much about this Qi-retaining technique, but after discovering this, his eyes lit up.

In fact, this qi-retaining technique is not profound. It is easy to be seen through when encountering masters, or when using true qi, it will also be exposed.

Even most people in their previous lives would have some tips to restrain their breath. They are not for show off or spoof, but for fighting and survival in the wild.

But this Qi-retaining technique is more systematic and formal. More importantly, a skill is formed on the panel. Although it only has 1 point, it can be improved by continuously increasing points in the future. When the level is higher, the effect will definitely be doubled.

At that time, even the master may not be able to see his reality and reality. He can lurk perfectly when escaping from powerful enemies or assassinating them.

Then, Zhang Feng copied the technique and took out the lighter he had prepared long ago. With a bang, he ignited the secret book. The secret book quickly turned into ashes, but a thin piece of gold foil the size of a palm was revealed, with not only words but also patterns on it.

"The rumors are indeed true!"

Zhang Feng's eyes burst into light, and he immediately picked up the gold foil and looked carefully. He found that this was a map, which not only contained ancient characters, but also depicted the structural route of an ancient undersea cave.

It turned out that in the early stages of the disaster in the previous life, a undersea cave appeared near Donghai City. Because of its high specifications and mysterious origin, it is also called Donghai Fairy Mansion.

When the Immortal Palace was born, it triggered three strange phenomena in heaven and earth, with dense auspicious clouds, rainbow light soaring into the sky, and thunder in the sun, attracting countless martial arts masters and powerful monsters.

But Zhao Hu had a cave map and knew the mystery of the cave better than other explorers. So when others fought to find treasures, he sneaked in from a secret passage and left quietly. Not only was he not discovered by anyone, he was not hurt at all, but he also gained more precious harvests than everyone.

"If I remember correctly, the Immortal Palace is still at the bottom of the sea and is hidden by the formation and will be reborn in three days. Even if I have a map, I cannot enter in advance. Since that's the case, I will make good use of these three days to improve my own strength!"

Zhang Feng studied the gold foil and made a decision in his heart.

According to rumors, Zhao Hu has gained a lot in the East China Immortal Palace, three of which are the most precious, namely a tiger and leopard roaring sky, a marrow-cleaning pill, and a spirit-gathering flag.

The martial arts are at the peak of the intermediate level and are already very precious. In combination with the bloodline transplantation technology that emerged in later generations, it integrates into the bloodline of tiger and leopard monsters or evolutionary beasts, or directly allows people with similar bloodlines to practice, and their power and potential are even more advanced.

Marrow-cleaning pill is an ancient elixir that can transform people into a complete transformation and greatly improve their qualifications and understanding. It is also extremely precious.

The spirit gathering array flag is even more expensive, with an ancient spirit gathering array engraved on it. You can gather the spiritual energy of heaven and earth by finding a place to insert it. Whether it is cultivated medicinal materials or directly absorbed and cultivated, it will be twice the result with half the effort.

In his previous life, when Zhao Hu was secretly exposed, he had already eaten the marrow-cleaning pill, and it was the martial arts and the spiritual gathering array that caused him to kill him.

But according to rumors, Zhao Hu had the opportunity to get more in the Immortal Mansion, but he missed it because of his lack of strength!

In addition, Zhao Hu was not discovered by other explorers in his previous life, but Zhang Feng may not have encountered an enemy.

The secret book was incomplete, which also resulted in a small lack of half of the gold foil. In other words, there were probably other people who had the opportunity to seize the opportunity, so he had to be careful.

Therefore, no matter what, he must become stronger.

Hurry!

After Zhang Feng used his strong spirit to remember the contents of the gold foil, he vomited his true energy and the gold foil in his hand immediately turned into powder and fell from his fingers.

Then, Zhang Feng took a deep breath and started practicing, consuming a large amount of level 4 medicine liquid. The progress of the exercises on the panel made rapid progress, and soon reached 99%.

"promote!"

Zhang Feng did not break through immediately, but pressed the + sign behind the technique, and the words "free dot" and "magic spirit" disappeared immediately. However, a large number of mysterious insights emerged in Zhang Feng's mind, and he quickly mastered the upgraded technique again.

At the same time, Zhang Feng felt that the quality of this technique had been improved again, reaching the intermediate peak instantly, making his body more pure. If it exploded, the increase in physical strength, physique, and speed would be much larger.

"Okay, when I get the Tiger and Leopard Soaring Sky Technique and consume another point of freedom, I can directly get an advanced martial art!" Zhang Feng clenched his fists and said to himself with a smile.

In fact, he can completely obtain the Tiger and Leopard Soaring Sky Technique and then transfer it, but the intermediate peak skills are so powerful that they are far less than those of the advanced skills. So now, although he consumes more free points, it is actually the most cost-effective.

There is an opportunity in my memory to directly obtain advanced skills, but all of them are far-reaching water that cannot relieve intimate thirst.

Obtaining advanced skills in advance will undoubtedly be more obvious to improve your strength and will be more beneficial to the next plan. If you obtain advanced skills in the future, you may be able to obtain the top skills after fusion several times.

Moreover, the combined technique is the most suitable for him!

Immediately afterwards, Zhang Feng poured the essence of the Rock Heart that he had previously stored in the bottle into a small bowl, took out another purification talisman and placed it in it. The talisman paper immediately emitted dazzling light, and bursts of black smoke with a foul smell rose from the small bowl.

After a moment, the vision disappeared, the light of the talisman dimmed a lot, but the essence in the small bowl became more crystal clear and full of tempting fragrance. It felt refreshed and happy when smelled, making people unable to help swallowing their saliva.

"It's time to break through!"

Zhang Feng nodded with satisfaction, carefully collected the purification talisman, took out another brocade box, took out a longan-eye-sized vermilion pill, placed it in the essence of a small bowl, raised his head and swallowed it all, then closed his eyes and began to attack the fifth level.

This vermilion pill is a barrier-breaking pill, worth 10,000 points, which seems cheap, but it is a sky-high price for ordinary warriors, and it is only effective for the first time. Therefore, when Zhang Feng broke through to level 4 before, he did not take it.

But now, his background in his previous life has been used up. Even if his attributes are strong, he can only stabilize his foundation. However, to make a breakthrough, it still takes time to settle, so in order to ensure a certain success, he has to use this spiritual pill.
Chapter completed!
