Listening to Su Qingya's words, Grandma Shenyu immediately took Su Qingya and 6 Weifeng to the dungeon as she said.

It was still the road that Su Qingya had walked, and it was also the environment that Su Qingya had seen. Grandma Shenyu stood in front of the door and made a hand seal to make a spell. The closed door was open, and Su Qingya saw the spy lying in one of the prison cells.

The spy was intact, and there was no trace of scar on his body. Even his breath had not changed from Su Qingya and 6 Weifeng before he left.

Su Qingya thought in her heart that she judged a gentleman with the heart of a villain. The people in the Fantasy Divine Palace treated "captives" very well.

If they were willing to vent their anger, the spies from the Illusion Demon Palace would never be so comfortable.

"Since you left, this spy has been sleeping. Qingya, what did you eat for him?"

Grandma Shenyu looked at Su Qingya with some uncertainty. This spy was too quiet, and it must be related to the pill that Su Qingya gave to the spy before leaving.

"A pill that will make him not feel any pain without making noise."

Su Qingya smiled at Grandma Shenyu and said, "Grandma Shenyu, open this door too, I need to go in."

Grandma Shenyu nodded, but this time she placed her hands in a groove in the door frame.

The moment the palm pressed down, a white light appeared, and the closed prison door opened in response.

Su Qingya couldn't help but look at this scene in surprise and said in surprise: "What is this? Fingerprint unlocking?"

In the 21st century, Su Qingya was used to password locks and fingerprint password locks. Many companies also need to press fingerprints when checking in at work.

However, after coming to Tianyun Great 6, Su Qingya never saw such a magical thing again.

"Fingerprint unlocking? What does this mean?" Grandma Shenyu looked at Su Qingya in confusion, but she had never heard of this word.

Su Qingya quickly explained: "This lock is used as the key by using the lines on your hands, and others cannot open it."

"That's not." Grandma Shenyu suddenly realized and smiled: "This lock is not something that can be opened by the old man. As long as you get the mark of the Mermaid clan, you can control these locks."

Su Qingya's eyes rolled around a few times, and she thought to herself the words "The Seal of the Mermaid Tribe".

This mermaid tribe's direct mark must also be a special existence, so is it a mark used as a key?

No matter what, this is the first time Su Qingya has seen this method in Tianyun Big 6. If she can, she really wants to learn it.

"Is this door unable to be opened without the Mermaid tribe's direct mark?" Su Qingya looked at Grandma Shenyu and asked.

Grandma Shenyu nodded but shook her head again, "It's not that she can't open it at all. As long as her cultivation is high enough to shake the barrier created by the kings of the mermaid clan with the power of the kings, she can destroy the defense system of the entire Phantom Temple Palace, and this gate will naturally be destroyed."

Speaking of this, Grandma Shenyu paused for a moment and looked at Su Qingya with a complicated expression.

Speaking of destroying the barrier of the Illusion Temple, isn’t there anyone in front of you who can do it?

In this way, wouldn’t Su Qingya destroy the defense system of the entire Phantom God Palace?

Su Qingya immediately reacted when she looked at Grandma Shenyu's expression. She explained: "I don't have the power to destroy the defense system of the Phantom Divine Palace, and can only establish communication with the barrier."

However, speaking of this, Su Qingya thought of something.

"Grandma Shenyu, can you let me give it a try?"

"Okay!" Grandma Shenyu responded without hesitation.

Facing the pleasure of Grandma Shenyu, Su Qingya was a little surprised, but what followed was the warmth and touch in her heart.

She had already left her breath in the barrier, and it was not difficult to control the barrier again now.

Su Qingya closed her eyes slightly and changed the barrier of the Phantom Divine Palace again. Then she closed the door in front of her, and placed her hands in the groove that Grandma Shenyu had pressed before.

Seeing Su Qingya's movements, Grandma Divine Fish was more and more surprised, but she remained silent and showed no sign of it.

It seems that she underestimated Su Qingya. She had not left here just now but was able to control the barrier of the Phantom God Palace again. It can be seen that although Su Qingya was young, she was not inferior to Liu Weifeng.

Perhaps, Su Qingya and 6 Weifeng can really help the mermaid tribe solve the current crisis.

When he pressed his palm, a slight coolness came, and Su Qingya felt a little repulsive.

But her hand had been pressed for a few seconds, but the door did not move at all.

Su Qingya was more interested in her heart. It seemed that this was true. Even if she controlled the barrier of the Fantasy Divine Palace, there would be no way to open the door without the Mermaid clan's direct mark.

Su Qingya's beautiful eyes turned and looked up at 6 Weifeng, "Come and try it."

6 Weifeng nodded and reached out and pressed his hand on the groove.

"Ding bee bee bee bee bee bee bee bee bee..."

In an instant, a red light suddenly appeared in the groove, and a sharp and anxious "beep" sound suddenly sounded.

The sound was extremely loud, and it felt like it was hitting straight into the eardrum. It was even more nervous than the sirens that Su Qingya heard in the 21st century.

Su Qingya was startled by the sudden sound, but 6 Weifeng seemed to have expected it, but she withdrew her hand indifferently.

"Grandma Shenyu, let the voice stop."

6 Weifeng turned his head and looked at Grandma Shenyu's mouth. The cold sound was like the melting ice spring water. In this tense and anxious atmosphere, people suddenly calmed down.

Grandma Shenyu nodded repeatedly and immediately made a mark on the door frame. In an instant, the sharp sound stopped.

"Go and tell everyone, don't be nervous, there is no danger." Grandma Shenyu turned her head and spoke to the little yellow croaker who had not yet come to her senses. The little yellow croaker nodded quickly and ran out in a flash.

"Qingya, what did you see?" Grandma Shenyu turned her head and looked at Su Qingya and spoke.

Su Qingya affirmed: "This door lock is really exquisite. I wonder if I have the honor to meet the master who designed this door lock?"

Su Qingya controlled the barrier, but did not give 6 Weifeng the right to enter and exit freely, so 6 Weifeng is an outsider to the barrier. So when he touches the door lock, he will activate the door lock's alarm system?

Exquisite, really exquisite.

This may be a very simple and common technology in the 21st century, but it is unique in Tianyunda6.

If Su Qingya can learn how to make this door lock, she can build the same door lock in Tianyun Big 6, which will greatly improve the safety.

Grandma Shenyu shook her head, "I'm afraid I can't. This lock has existed for tens of millions of years, and I have never seen anyone with a design." Su Qingya was inevitably regretful when she heard this, but she heard Grandma Shenyu say again...
