Zhou Qinghan was overjoyed upon hearing this and quickly bowed respectfully, saying, "That's enough. I would like to thank Immortal Qing Shang."

Cen Biqing nodded slightly, then raised his hand and said, "You go back first. I will send you a letter when I have news. Where is your cave?"

"Peach Blossom Mountain." Zhou Qinghan said.

"Okay." Cen Biqing nodded.

Zhou Qinghan immediately thanked Cen Biqing again, then said goodbye and left the hall and left Lingxia Mountain.

Shortly after Zhou Qinghan left Lingxia Mountain, dark clouds suddenly appeared in the sky of Yangxia County.

Suddenly, there was a loud noise in the sky, followed by a series of thunder-like explosions in the dark clouds. At the same time, a strong wind blew between heaven and earth. The strong wind blew on the body like a knife, and all the cultivators below the Yangshen level felt very painful.

The little cat demon and all the busy little demons in the Lingxia Mountain Medicine Garden were blown to and fro by the wind, their faces were scratched by the wind, and their clothes were torn by the strong wind.

Cen Biqing and Master Cai Jing immediately transformed into two beams of fairy light and flew into the air. Then they raised their hands and used their magic power to activate the Lingxia Mountain's protective formation.

Suddenly, the mountain-protecting lights shone, and the strong wind was immediately blocked outside. The little demons were finally able to steady their bodies, screaming and using their magic power to run back to the cave.

At the moment when the mountain protection formation was set up, two figures suddenly fell from the dark clouds, crashed into the mountain protection formation at an extremely fast speed, then spat out two mouthfuls of blood and fell downwards.

Seeing this, Cen Biqing and Master Cai Jing originally thought that it was a fight between cultivators and did not want to get involved in such trivial matters, but they soon saw that the two fallen people were wearing magic armor of the Thunder Department.

"A true fairyland, and there's also a golden armor of heavenly thunder. It's the Thunder Department's Heavenly General!" Zhenren Cai Jing exclaimed. Upon hearing this, Cen Biqing immediately said, "Save him."

But before the two of them could take action, two sword energies suddenly shot down from the dark clouds. The sword energies were so powerful that they tore through the void and killed the two thunder generals.
