As soon as he entered the cave, he sat down and began to meditate, closing his eyes and trying to feel, he felt the air around him with his heart, to feel the breath of the earth, and his whole person seemed to be integrated into this natural environment.

Time passed gradually, and Zhou Dezhou gradually felt that the spiritual power in his body began to change, and the spiritual power surged towards his nervous system, and then turned into a shock wave, sweeping through his body, and the air around him began to tremble.

Zhou Dezhou felt that he was breaking through the bottleneck, and he decided to go all out to complete this breakthrough.

"Boom!" His body suddenly began to tremble, and his whole person seemed to be bombarded by some powerful force. Then he felt a powerful momentum emerge, shaking the entire cave, as if even the earth was trembling.

However, the Chaos God and Demon Body helped him block this impact, and the Ring of Cosmos also condensed an incomparably hard protective shield beside him.

Zhou Dezhou still has to accept the test of the thunder tribulation, this time, can he stop it?

At this time, the sky above Zhou Dezhou had changed color and turned red. And the red thundercloud also slowly approached the sky above Zhou Dezhou.

Facing the thunderclouds, Zhou Dezhou smiled contemptuously. "Hmph, I'm a person with a Chaos God and Demon Body, and your little thunder tribulation is not enough for me to stuff my teeth." He secretly made up his mind in his heart to prepare for this test.

As the thunderclouds gradually approached, Zhou Dezhou's whole body began to exude a powerful momentum, like a flame full of energy, ready to burn everything at any time.

Finally, the thunderstorm struck, and a huge thunderbolt enveloped the entire cave in it. However, the protective shield of the Ring of the Universe blocked most of the power, and the Chaos God and Demon Body left Zhou Dezhou unscathed.

Zhou Dezhou felt that the power coming from his body was getting stronger and stronger, and his spiritual power had reached a new height. Under the baptism of the thunder tribulation, he finally broke into the realm of immortals and became a real "immortal".

"Hahaha, I'm an immortal!!" Zhou Dezhou laughed loudly, excited. He felt that his strength had risen to a new level, and he had mastered more power.

His gaze seemed to sweep the entire cave and saw a dim but somewhat lit corner. He paid a certain price to obtain the power to break through the Immortal Ascension Realm, and he needed more strength to deal with greater challenges.

So, he began to walk towards that corner, and at the same time, the Ring of the Universe brought him more surprises.

When Zhou Dezhou approached that corner, he saw something. It was an old book, and the words on the cover were blurred, but judging from the font, it should be an extremely precious cultivation secret book.

Zhou Dezhou immediately picked up the book and felt the extremely rich aura it exuded, which showed that the cultivation methods recorded in this book were very precious and definitely not ordinary.

When he opened the book, he saw that it recorded a cultivation method called "Nothingness", which was said to allow cultivators to possess the power of heaven and earth, and achieve the ability to break through the sky and penetrate the realm, which was really a strange technique that could be encountered but not sought.

Zhou Dezhou felt an impulse ignite in his heart again, and he knew that he was moving towards the path of becoming an immortal cultivator. The appearance of this book is also the opportunity given to him by fate.

In order to better grasp this cultivation method, Zhou Dezhou decided to start practicing. He took a few deep breaths, circled the space around him, and the breath of his whole body gradually converged, and he entered a quiet cultivation state.

In the process of cultivation, Zhou Dezhou's state of mind was constantly immersed in heaven and earth, feeling the powerful aura brought by nothingness. His body gradually became transparent, as if he was merging into the entire heaven and earth, and seemed to have an ability to pass through the realm.
