Diana and Sun Rongmu were sitting cross-legged, continuously absorbing the rich spiritual energy of heaven and earth around them to practice.
Far away from the altar, there are many monsters and beasts, and they are all practicing at the moment.
The spiritual energy of the surrounding heaven and earth is as thick as white mist, just like a foggy day.
If you look carefully, you can find that these mist-like spiritual energies have a certain trajectory. They continue to gather and rush towards the center of the altar.
In the center of the altar, Xu Qingyun sat cross-legged, his eyes closed tightly, and his whole person seemed to have entered a state of trance, without any other sound except for his weak breathing.
Xu Qingyun is still surrounded by golden runes, and there is a golden totem on his head.
More than a month has passed, and Xu Qingyun has maintained this posture without changing.
He was like an immortal who entered selfless seclusion to practice, wandering in the world.
If someone could see through it at this moment, they would definitely find that Xu Qingyun's meridians were filled with rich spiritual energy, and he was constantly walking around the world under the operation of the technique, tirelessly, over and over again.
The spiritual energy in the Dantian is already overflowing, as if it may burst at any time and has reached its limit.
If there are powerful immortal cultivators who see this scene, they will definitely know that Xu Qingyun is at an extremely important breakthrough point.
And you will be surprised by the amount of spiritual energy that Xu Qingyun's Dantian can contain, reaching an extremely terrifying amount.
The sky is at its peak, and the Dantian is complete.
If other people had practiced so much and absorbed spiritual energy, they would have broken through long ago, or they would have exploded and died.
But Xu Qingyun persisted for more than a month and still had no real breakthrough.
The harder it is to break through in cultivation, the stronger you will be after you break through.
The same realm of strength is also divided into three, six or nine levels.
There is no absolute fairness in this world.
In fact, Xu Qingyun spent more than a month not only cultivating and absorbing the spiritual energy of heaven and earth, but those golden runes and golden totem belts gave him even more precious things.
The Dantian in Xu Qingyun's body seemed to be about to burst, which was a sign of an imminent breakthrough.
There are thunderclouds constantly gathering in the sky, and the day is like night.
Those thunderclouds are not only condensed by the great formation of heaven and earth. The thunderclouds cover the sky and the sun. Electric arcs flash within the thunderclouds, as if the power of divine punishment may fall at any time.
Both Diana and Sun Rongmu, who were practicing, felt something strange in the sky.
The two of them stopped practicing one after another and looked at the thundercloud-filled sky in amazement.
"What's going on? What happened?"
Sun Rongmu's face was full of doubts, and he was surprised in his heart, looking at the sky that looked like the end of the world was coming.
He felt a breath that was so oppressive that he felt like he was suffocating.
This feeling comes from the dense thunderclouds in the sky.
This thundercloud is not normal, absolutely not normal. Even if it is going to rain heavily, it is impossible for so many thunderclouds to gather at once, and he can't see the limit of the rain, some are just signs of thunder.
Diana was also very surprised, but after the surprise, she soon understood what was going on.
A pair of beautiful eyes looked at Xu Qingyun, who was still practicing with his eyes closed in the center of the altar.
"Thunder Tribulation is the thunder calamity of cultivation!"
"Xu Qingyun, he is about to break through!" Diana said.
When Xu Qingyun taught her the immortal cultivation techniques, he naturally also introduced her to the immortal cultivation system, including the practice of overcoming tribulations.
Although Diana had never seen anyone else practicing to overcome the tribulation, she knew that this must be the thunder tribulation caused by Xu Qingyun's upcoming breakthrough.
Only this reason can explain the sudden gathering of so many thunderclouds in the sky.
"What?! Practice overcoming tribulations, thunder tribulations?!"
