As they inspected the way, they discovered restrictions in many places. Fortunately, none of them were offensive.
They spent over a month carefully searching the entire secret realm, killing every sixth-rank demon beast within.
Five of the upper sixth-rank demon beasts possessed particularly formidable abilities. They set up a seventh-rank formation, lured the demon beasts into it, and easily exterminated them.
The demon beasts had not taken human form, so their strength was still lacking.
They found fifty-five ten-thousand-year spiritual herbs and five twenty-thousand-year spiritual herbs in the secret realm. The most precious was a Snow Orchid Flower over twenty thousand years old. The Snow Orchid Flower was the main ingredient for refining Snow Orchid Pills, which were highly effective at healing injuries caused by lightning strikes.
Besides that, there were various spiritual woods more than ten thousand years old. The most precious was Fire-Severing Wood; Fire-Severing Wood over ten thousand years old could be used to refine fire-attributed Heaven-Piercing Spirit Treasures, and their power was considerable.
There were quite a few spirit beasts and spirit insects in the secret realm. Among them was a type of Snowblade Fish, whose flesh was delicious and could be used in cooking or fed to spirit beasts.
After they left the secret realm, Ye Xue came forward to greet them.
"Patriarch, why were you inside for so long?"
Ye Xue asked doubtfully.
"We thoroughly cleaned out the secret realm and found its control hub. It will still be very difficult for cultivators below the Body Integration stage to enter the secret realm."
Han Zhangxiang explained.
"We should give it a try. If we can open the secret realm, we should also set up some formations to block our enemies."
Ye Xin suggested.
They attacked the secret realm for more than half a month
