"Can you open the door?" Luo Ling asked hurriedly.

"Well, sister, have you seen the two holes in the keyhole in the wooden door over there? Let's put the ring in later. Be careful, you must be at the same time." Luo Huan finished his emphasis and stepped forward with Luo Ling.

He hid the color and shape of the place in the overall shape and pointed the extremely difficult keyhole to see for Luo Ling.

The twins’ natural tacit understanding gives them a little more confidence when completing this step.

After the transfer, the two rings of gems were embedded in their respective positions as if they were part of the door.

The part of the ring holder is pressed into the special track installed in the door, and it cleaves into the precise parts hidden inside the wooden board.

"No wonder it must be the original base and gem of the ring. It turns out that the ring itself is the key." Luo Ling sighed. It was the first time she encountered such a clever design. That kind of precision is simply a masterpiece in the hands of a master.

"Don't relax. Now, keep the same movement as me. After three seconds, we will press the gem together and send it back to its original position." Luo Huan finished reminding him, focusing on the countdown, "Three, two, one, press."

Luo Ling didn't think at all, but instinctively followed Luo Huan's orders. Whether it was the rhythm or the tacit understanding, it seemed that he had rehearsed a thousand times in advance. The two of them were completely, exactly the same.

The gems on the ring were pressed to the depths of the door panel by a constant speed.

Two crisp sounds came at the same time, mixing together, making it impossible to tell which side is the first.

Two round deep holes appeared on the door panel and couldn't see clearly what was inside.

"Put your finger in again. The size of this hole should be the index finger." Luo Huan didn't have any expression of excitement on her face. She commanded her very seriously and was calm and comfortable.

"Wait." Hei Jieming suddenly spoke, a drop of sweat on his forehead, and rolled down his cheeks. "Huanhuan, think about it carefully, and you must not make mistakes."

If the judgment is wrong, the self-destructing program will be started instantly. It is still a long distance away from the ground here, so it is not easy to leave safely.

"I did not get the wrong steps, I'm sure." Luo Huan replied gently. At this time, there was no time to explain more to Hei Jieming, but just said quickly, "Sister, your fingertips may hurt a little later. You can hold it down and don't retract. Let's put your fingers in together. The three-second timing starts, three, two, one... Oh, it hurts really."

Something sharp was instantly pierced by the fingertips.

Luo Huan endured the discomfort and instead sent his finger deeper.

Luo Ling felt little pain. During this period, she turned her face and looked at Luo Huan strangely, "Do you know what will happen? You have known how to use a ring to open the door?"

Luo Huan sighed, "Well, I just remembered it. When I was a child, my father often played a secret room escape game with me. One of the most critical steps was to open the door and leave. He once taught me this way to open the door."

"Why have you never heard you mention it?" Luo Ling saw that Luo Huan had already pulled out his fingers, so he also pulled out his fingers, put them in his mouth, and sucked the remaining blood.
