"Zheng Zheng, Brother Rong! Are you back?"

They all stood up.

Yun Zheng was caught off guard by the sight of their swollen and bruised faces. She was startled and raised an eyebrow, asking with a smile, "Why...did you end up like this?"

Feng Xinglan was relatively calm: "I had a fight with the turtle monster and the others."

Yan Chen smiled and said, "We didn't lose, it was a tie."

Yun Zheng: "..." When they were training, they didn't hit people in the face...

The Emperor suddenly said, "The passage of time here is several times faster than that of the Sky Continent, so you can practice in the Demon Realm for a while before leaving."

After a pause, he added, "I will personally teach the eight of you how to use an ancient formation together, as well as some martial arts techniques."

"Ancient formation?!"

The friends looked at each other and were all curious about this ancient formation.

The eight members of their Fengyun team also learned a formation, which was used in the anti-demon war in Dongzhou before - the elemental killing formation.

What kind of formation will it be this time?

Yun Zheng raised her eyes and glanced at the Emperor, suppressing the thoughts in her mind.

…

In order to master the ancient formation, the eight members of the Fengyun team practiced day and night, and their occasional relaxation time was to fight with the turtle monsters.

The Emperor not only taught them the ancient formations, but also gave them a book of martial arts and combat skills suitable for each of them.

Four months passed in a flash.

During this period, Yun Zheng followed Liang Guanren to find out the reason why beast tides would break out in the western region of Qiongtian Continent every year.

Because the demon world itself is adjacent to the space of the western region, and even overlaps faintly, the demonic energy of the demon world sometimes leaks into the western region. That demonic energy has both advantages and disadvantages for the spirit beasts.

The advantage is that it allows the spiritual beasts' cultivation and reproduction capabilities to increase rapidly. The disadvantage is that once the energy accumulates to a certain point, it will backfire wildly, eventually causing them to lose their sanity.

She had previously strengthened the seal of the demon world, so very little demonic energy leaked out now.

It might ease the beast tide in the western region.

Half a year after the Fengyun team arrived in the demon world, they had already mastered 80% to 90% of the ancient formation, so they were ready to leave the demon world.

Half a year in the demon world is only half a month in the Sky Continent.

Liang Guanren did not leave the demon world. He looked at Yun Zheng with a serious and respectful expression, then lifted his robe and knelt down solemnly.

"I will be in the demon world, waiting for the little ancestor's return. When the time comes, I will definitely lead all the demons to welcome you—"

"The demon god has returned to the world!"
