The system is unreliable, the host can only save herself

After a while, the sound of "bang bang bang" of monsters colliding was heard from the formation barrier at the entrance of the cave.

Unfortunately, these blood bat monsters don’t know that the fifth-level defensive magic circle is not something they can shake.

Su Jingyu listened carefully for a while. These big bats were quite stubborn. They kept hitting them for a long time but they wouldn't leave even if they couldn't be knocked away.

Su Jingyu muttered, "What a bunch of stubborn people!"

Until they leave, she doesn't dare to go out easily. Now it depends on who has more patience and can afford to waste time!

Thinking of this, Su Jingyu simply walked around in the cave.

The area of ​​the small cave is not large, there are no treasures inside, and there are traces of human activities left, so it seems to be of little value.

The divine sense scanned the cave, but could not find any other exit.

She always felt that something was wrong, but couldn't figure it out for a while, so she gave up the idea of ​​investigating and flashed back to her own space.

In the space, Fang Muqing was directing the puppets to harvest a batch of mature spiritual plants when he saw Su Jingyu coming in.

He was still a little confused: "Xiaoyu, didn't you go to the secret realm to train? How did you have time to come in?"

Su Jingyu said helplessly: "Uncle Master, I am now in the secret realm. I am so unlucky. As soon as I came in, I was chased by a group of fourth-level blood bats. Now I am blocked in a cave."

She told Fang Mucheng everything that happened along the way, and at the end, she asked Fang Mucheng for his opinion.

"Have you examined the cave carefully?"

"I scanned it with my spiritual sense. It's just an ordinary cave. There are obvious signs of human activities inside. It should be that a cultivator lived here before."

"Didn't you just say that the spiritual consciousness can't penetrate the back of the cave? Isn't this abnormal?"

Su Jingyu heard it and thought, oh yes! So this is what she felt was wrong.

According to the current strength of her spiritual awareness at the Nascent Soul stage, she should be able to see through it.

Su Jingyu walked into the cave again and observed carefully from the back of the cave.

Suddenly she saw a groove near the top of the cave.

Because the soil in the groove is similar to the surrounding soil, if you don't look carefully, you really can't tell the difference.

She suddenly had some guesses in her mind.

In order to confirm her guess, Su Jingyu used several cleaning techniques on the groove, and as expected, the true appearance of the groove was revealed.

After performing the cleaning technique on the top of the cave, a large piece of smooth and flat wall was revealed, with a very obvious groove on it.

In order to observe better, Su Jingyu took out a night pearl, circulated her spiritual power to hover her body in the air, and then gently touched the circular groove with her hand.

The grooves are made of some special jade. Although it feels very soft to the touch, it may have a hint of spiritual energy, as if it is the jade used by the powerful people in the secular world.

Su Jingyu suddenly remembered that she seemed to have a jade bead with a material similar to that of the groove. She bought it at the market at the foot of the Divine Sword Sect when she went out for training after she had achieved great perfection in her foundation building.

Thinking of this, she returned to the bamboo building in the space again and took out the jade pendant from the treasure chest in the bedroom.

"Xiaoyu, why are you back so soon?"

Fang Mucheng saw her rushing in without saying hello and rushing back to the bamboo building. Less than ten breaths later, she was rushing out again, so Fang Mucheng asked curiously.

"Uncle Master, I seem to have found a different place in the cave, so I came back to get something to try."

After she finished speaking, she wanted to go out, but was stopped by Fang Muqing.

“Wait a minute, take Xiao Wu out to help you, so that I can feel at ease when you are alone outside.”

Xiao Wu was a sparring puppet that her master gave her when she was in the late stage of foundation building. His highest strength was at the early stage of golden elixir cultivation.

She gave the previous foundation-building puppet to her junior sister Shangguan Yuaner.

"Okay, thank you for thinking about me, uncle."

Su Jingyu went to the spiritual field first, called Xiao Wu who was taking care of the spiritual field, and left the space together.

Returning to the cave, she quickly took out the jade pendant.

I compared it with the groove on the top of the cave and found it fits perfectly.

This jade pendant that she accidentally found turned out to be the key to open the groove here. She wondered what would be found after opening it. Su Jingyu was suddenly a little excited.
