It is precisely because of this that the two great elders Wu Qingxin and Qi Ziyi came to guard the treasure house of the underworld, and there was no one disturbing them here, so they could practice with peace of mind to strive to break through to the "innate" realm.

In addition, not far from Wu Qingxin and Qi Ziyi, there is a wooden shelf about one meter high, with a model of the courtyard on it. Four yellow talisman papers are pasted in four directions of the model, southeast, west and northwest, respectively, and each talisman paper has the word "thunder".

Suddenly, a talisman paper flew automatically to the sky above the courtyard model and floated, emitting a mysterious aura.

"Huh?" Wu Qingxin was in amazement. He looked at the talisman paper floating above the model and said in surprise: "Someone broke into the yard and alarmed the thunder formation. Who is so bold?"

"No matter who it is, it is a death sentence to dare to break into the forbidden area of ​​the treasure house without authorization." Qi Ziyi snorted coldly and said, "When the person in the yard is struck by lightning later, the thunder formation will automatically stop. Then go collect the body for him and see whose disciple is not eyeing."

"Okay, let them have a long memory." Wu Qingxin nodded with a smile.

Obviously, they thought it was a disciple of the Underworld who broke in by accident.

After waiting for a few minutes, the thunder formation did not stop, but another thunder talisman floated in the air.

Qi Ziyi was shocked: "Only after the opponent has survived a period of time and has not died, the thunder formation will automatically increase the power of the formation, and the thunder falling in the formation will be twice as high.

For a hundred years, only when Sect Master Song Xuan proved his cultivation and broke into the thunder formation alone, he only aroused two thunder talismans. Who was the one who broke in? He had such powerful strength. Could it be that the person who broke in was the sect leader?"

"Impossible." Wu Qingxin immediately shook his head: "If he was really the sect leader, he would definitely notify us in advance so as not to have misunderstandings."

"Since it's not the sect leader, who is still so capable? Is someone trying to break into the thunder formation with the intention of being ill-treacherous to the treasure house?" Qi Ziyi snorted: "It's a pity that the thunder formation has been activated. If you open the door, it will only reveal the aura of the formation, resulting in the unstable thunder formation. Otherwise, I really want to see who is so bold."

"No need to worry. Now that two thunder talismans have been activated, it won't take long to die in the thunder. It's not too late for us to see his true face in Lushan."

"That's all." A look of contempt flashed in Qi Ziyi's eyes: "If you dare to break into the thunder formation, the only consequence is death!"

In the formation, facing the falling sky thunder, Chen Feiyu could only jump to dodge.

Not long after, the thunder falling from the sky had changed from one to two, and it was already a little difficult for Chen Feiyu to hide.

With a thought, he used his mental power, intending to cover the entire radius of 200 meters to find the array eyes to break the array.

However, as soon as the mental power was released, it was suppressed by the power of the formation, and the mental power could only be maintained within three meters of the whole body.

"The Underworld is worthy of being a thousand-year-old sect. It is such a mysterious and domineering formation. The person who set up the formation was definitely a genius." Chen Feiyu was shocked and admired in his heart, and kept jumping to dodge.

Thunder and clouds gather in the sky, becoming more and more ferocious.

Not long after, the two thunders had turned into four, constantly chasing Chen Feiyu!

Powerful, strong and powerful!

Chen Feiyu's face changed suddenly.

At the same moment, in the shocked eyes of Wu Qingxin and Qi Ziyi, the third thunder talisman slowly floated into the air, reflecting with the two previous thunder talismans, exuding a mysterious thunder aura.

"Three...three thunder talismans?" Qi Ziyi opened her eyes wide and was shocked: "This is the first time in a hundred years that anyone can support the third thunder talisman in the thunder formation. Who is this person?"

Wu Qingxin said in disbelief: "Even if you and I join forces, we can't support the third thunder talisman. The strength of this uninvited guest is definitely extraordinary.
