Regarding Rehmannia, everything is just a legend, and no one knows the specific efficacy and ability. Even the Ghost Hand Fairy who prescribes the prescription has a slight understanding. Zi Donglai had no choice but to look for the medicine effect of resurrection. If it really doesn't work, he has to think of other ways. After all, the Ghost Hand Fairy said that Rehmannia is effective. As for what effect it has, it can only be found according to the situation in the future.

Now Zi Donglai is not worried about whether he can find the Rehmannia. What he is more worried about now is that the Ghost Hand Fairy doesn't know the effect of the Rehmannia. If he finds how the Ghost Hand Fairy uses the Rehmannia to treat Cheng Ruoyi's disease, if Cheng Ruoyi is used for the Rehmannia experiment, he will never allow it.

Zi Donglai took Taicang Holy Rat and did not walk the passage of the land he walked on last time, because he did not want to leave too many whereabouts of human activities. Although he had absolute confidence and did not leave any whereabouts, sometimes things were not something you could control, so Zi Donglai took Taicang Holy Rat and entered the Demon Realm directly from the entrance and exit of the Demon Realm of the 100,000 mountains in the southeast, and he did not disturb the War God Wuxiang, who was guarding the 100,000 mountains in the southeast.

Xiao Hei was still repairing the physical injuries in the formation. It didn't think that Zi Dong would take some time to go back, but it was less than half a day before Zi Dong came back.

"I've found out about everything." In the surprised expression of the Taicang Holy Rat, Xiao Hei's thick voice frightened it so much that it rushed towards Zi Donglai. "Why is it?" When rescuing the Cheng family, Xiao Hei had seen the Taicang Holy Rat, and suddenly found it beside Zi Donglai, and Xiao Hei looked at him with a question.

"The demon world it was captured later ran to the earth through the passageway, and accidentally encountered it, and also discovered a new demon world passage." Zi Donglai explained to Xiao Hei that Xiao Hei also knew a lot about the passageway between the demon race.

"Oh, then you bring it here?" Although Zi Donglai had explained it, Xiao Hei still didn't understand what Zi Donglai meant with Taicang Holy Rat.

"It takes too much time to dig it hard, let the Taicang Holy Rat dig the hole in." After Zi Dong finished speaking, he hugged the Taicang Holy Rat that was crawling on him like a koala, and then assigned a task to it.

"Jiji, Jiji." The Taicang Holy Rat supported his body with two hind paws and pointed its little head to signal that it understood.

Zi Donglai said nothing more, Xiao Hei leaned against Zi Donglai. Then Taicang Holy Rat began his work. Although Taicang Holy Rat is a spirit beast, his ability to dig holes is not inferior to that of a squirrel. For a short while, Zi Donglai and Xiao Hei could not see the thin body of Taicang Holy Rat.

The dirt was constantly thrown out from the entrance of a cave with a diameter of about 30 cm, and the amount of dirt was thrown out became less and less, which means that the hole was being dug by the Taicang Saint Rat. Although Zi Donglai had already told the Taiyigar Saint Rat what he was looking for, it was just an image gesture. Don’t look at what the Taicang Saint Rat got below. Zi Donglai was also waiting with anticipation, and he also hoped that the things Taicang Saint Rat were exactly what he wanted.

"Jiji, Jiji." After a while, the Taicang Holy Rat crawled out of the hole he had made. The hair on his body was covered in soil, and his face looked pitiful, and he kept coming to Zi Dong.

"What's the situation?" Xiao Hei's thick voice sounded. Zi Donglai was also a little surprised when he saw the Taicang Holy Rat who had not obtained anything.

"Wait for me to use my spiritual sense to see." Although Zi Donglai was surprised at the performance of the Taicang Holy Rat, he still had to use his spiritual sense to determine what was under the root system of the dead tree. In the past, because of the powerful vitality of the root system of the dead tree, Zi Donglai's spiritual sense could not accurately find out what was strange under it. Now, because Taicang Holy Rat has made a hole, Zi Donglai's spiritual sense can clearly see what was on the root system of the dead tree as long as it passes through this hole.

"Yeah." Zi Donglai frowned slightly, and then continued to investigate. Xiao Hei and Taicang Holy Rat stood quietly beside Zi Donglai, not even daring to let out a breath, for fear of disturbing Zi Donglai.

"How is it?" Xiao Hei saw Zi Donglai's frown spread out, and he knew that Zi Donglai's spiritual sense had already explored the cave.

"It's strange. There was something underneath, but now it seems to have been poached." Zi Donglai could not accurately describe the scene in front of him. There was a special thing under the root system of the dead tree, but now it has been poached, and the dead tree is still standing here.

Zi Donglai had a headache. He might be one of the best in cultivation, but when it comes to this kind of job of stealing the sky and changing the sun, he can't do it, even if he can't think about it.

"Someone moved the thing below?" Xiao Hei's expression was not visible on his face, but his words were filled with shock. It was the same as Zi Donglai thought about it. The dead tree had never been passive, but there was no thing under the root system.

"Jiji, Jiji." The Taicang Holy Rat looked at Zi Donglai's frowning, and after screaming twice, he returned to the hole he had just dug, as if it had discovered something.

Zi Dong looked at the Taicang Holy Rat who had crawled into the cave again, and did not react for a moment what it was going to do, but when the Taicang Holy Rat came out with a scale in his mouth, Zi Dong came to see the light.

The Taicang Holy Rat holds nothing else in his mouth, but a piece of armor-piercing monster scales. This kind of monster is very common in the demon race, and it has its figure in almost all the mountains and forests. The armor-piercing monsters have thin and sharp bodies and are covered with scales. They are born to live in soil and rocks. Their intelligence is not as good as low-level monsters. It can be said that they have no intelligence, and they are small in size and poor in combat ability. The demon race will hardly train them to use for combat. They are just ordinary monsters and never pay attention to them.

"Someone is training this kind of monster?" Zi Donglai stared at Xiao Hei. After all, Xiao Hei was a monster, so he knew more.

"I haven't heard of these things. They have no intelligence or combat power. Although they are easy to train, they are useless." In Xiao Hei's only memory of the demon world, he didn't remember anyone who trained the mountain monster. But it then said to Zi Dong: "Maybe it is possible, but we don't know much."

"Can you find them by looking for the breath?" Zi Donglai no longer struggled with the previous question, but lowered his head to ask the Taicang Holy Rat. Although the things were taken first by others, if you can find the person who takes them according to the breath, you can do it.

"Jiji, Jiji." The Taicang Holy Rat jumped towards Zi Dong, and then ran towards the other side of the forest at an extremely fast speed.

"Come back." Zi Donglai laughed at him as he was too holy rat. If he could find it, he was not in a hurry now. He wanted to study the dead tree in front of him first.
