***************************************

Staring at the box that was quite old, Zhou Xuanji looked at it several times, but there was a bit of weirdness in his eyes. It was impossible to tell how the box was opened from the appearance. He used a little effort and did not open the box directly.

The gift given by the thief ancestor Song Xuande actually had such a meaning hidden. It was obvious that he used the method of thief to use a very strange lock. I don’t know what he wanted to express.

However, Zhou Xuanji has not conducted in-depth research on such things.

Holding the box up, Zhou Xuanji looked at the edge of the box carefully for a few minutes. There were complex patterns on the edge of the box, but a crescent-shaped pattern in the corner attracted his attention.

It seems that this is the key to opening the entire box. Zhou Xuanji sighed in his heart, but he was a little helpless. This is obviously a little bit of conscience that Song Xuande played, but he couldn't break it with great force. After all, he didn't know what was inside. If the entire box was destroyed, the things inside might be destroyed together.

Since he came back, he had been sitting on the sofa and staring at the box. It was not until then that he understood what was going on. However, he did not worry about it, but instead put the box on the coffee table, with a little thought flashing in his eyes.

At this moment, Ling'er walked out of the room. She carried a small bag and greeted Zhou Xuanji: "Brother, I'll go out to buy some vegetables, you can sit at home."

As she spoke, her eyes fell on the box on the coffee table. Her eyes shrank and she asked uncertainly: "Brother, why have you been studying this kind of hybrid lock?"

Zhou Xuanji's spirit was shocked and asked with some surprise: "Ling'er, do you know what this is?"

While speaking, he felt a little surprised. Just a glance, she could see the secrets contained in this box. It was incredible.

Ling'er slowly walked over, sat next to Zhou Xuanji, picked up the box, just glanced at the crescent-shaped pattern and said: "Brother, you can't see any signs of locks from the outside of this box, that is, you use the inner lock. This crescent-shaped lock is the part of the outer lock, and this method of combining internal and external locks cannot be accessed by ordinary people, unless you are a real person in this industry."

When he was talking, Ling'er had some memories on her face, but she had a sense of caution. Obviously, seeing this lock reminded her of some things in the past, which made Zhou Xuanji reach out and pat her shoulder and whisper: "Ling'er, the past has passed. Some things, technology and craftsmanship will not have good or evil. You don't have to care about those bad memories. The important thing is the present."

"Brother, do you need me to open this box?" Ling'er nodded, with a little peace between the corners of her eyebrows. Finally, she turned her head to look at Zhou Xuanji, with a dependency-like smell in her expression.

Zhou Xuanji raised his lips, but a touch of warmth flashed through his heart. Finally, he nodded and said, "Ling'er, can you open this box?"

"Well, this kind of crescent lock is the most difficult lock to unlock, and it is just an outer lock. There must be other arrangements for the inner lock. We call this arrangement a trap lock, but I can still open it. As far as I know, there will be no more than five people in China who can unlock this lock."

Ling'er's voice was a bit confident. As she spoke, she picked up a paper pin from the shelf under the coffee table, and directly used her finger to insert the pin into the keyhole carefully.

Zhou Xuanji looked at her movements, and a hint of care appeared in his eyes. This hint of care had a doting smell. This girl seemed to be willing to do anything for him. Moreover, her talent in unlocking should be truly first-class. No wonder she was praised by Song Xuande.

Ling'er put the box flat on the coffee table, then squatted there, took out the second pin, held the two pins with two small hands, constantly adjusting the direction, exploring in two different directions, with gentle and careful movements.

"Brother, there are three locks here, two of which must be opened at the same time, otherwise they will be locked. I have to open these two locks first. The installation of these two locks is very skillful. They are actually on the same horizontal line, which increases the difficulty of unlocking, because it may trigger the mechanism if you are not careful."

Ling'er adjusted the pin in her hand and explained in a low voice, a blush flashed across her little face because of excitement.

Zhou Xuanji just responded, but said nothing. After all, he really couldn't understand these professional terms. Fortunately, Ling'er didn't continue to say it. Her white fingertips were just constantly jumping, as if they were playing the piano, with a certain rhythm, and like a butterfly passing through the flowers, which made people feel dazzling.

He kept maintaining such frequency and movements like this. Ling'er lasted for about five minutes. Two slight "click" sounds sounded at the same time. At this time, Ling'er's smooth forehead was already sweating.

Turning his head to look at Zhou Xuanji, Ling'er's face was a little proud, and her smile also brought a bit of girlish charm, innocent and natural.

At this moment, it was obvious that she naturally revealed the joy in her heart because she did something for Zhou Xuanji. All of this was because of her admiration for Zhou Xuanji.

Wiping away the sweat from his forehead with his hands, Ling'er let out a sigh, moved his fingertips again, then stopped, and said with a pursed mouth: "Brother, there is also the last lock, but this lock is the most difficult. Few people can open such locks safely, but for me, such locks are the easiest. I believe that no one in the world will be faster than me to open such locks."

As she spoke, her fingertips moved. This time was different from the last time. The last time she was just the index finger and middle finger were constantly vibrating. This time, the ten fingers were moving at the same time. The power and method of vibration were completely different, with a certain crossing rhythm, but the speed was faster.

In just a few dozen seconds, there was a "crack" sound from the box. Zhou Xuanji stared at Ling'er in amazement, reached out to rub the top of her head, and sighed a little: "I really didn't expect that you girl has this talent. This is the most beautiful performance I have ever seen."

Ling'er raised her neck and smiled slightly, "Brother, to put it bluntly, this is nothing. The last lock must be opened within one minute and oscillates at different frequencies. If it exceeds one minute, it will never be opened. This is what we call a shock lock. I use different fingers to emit different forces. Every rebound force on the pin will prompt the power of the next pop. In this way, following the power transmitted from the pin step by step, as long as there is no mistake in every step, the lock can be opened soon."

After saying that, Ling'er stood up, straightened her waist, placed her hands in front of her lower abdomen and rubbed the corners of her clothes, and said with a red face: "Brother, then I'll go buy vegetables."
