Wang Wanzhi suddenly made a sound and stopped.

Yan Yu asked curiously: "Miss, have you solved it?"

Wang Wanzhi responded: "No,"

Yan Yu was surprised: "Is it difficult? Even the young lady can't solve it."

Wang Wanzhi said: "No, this Luban Lock still has a lock and needs a key." He pointed to a small hole exposed after the Luban Lock changed its shape.

Yan said in a loud voice: "I'll go find him and ask for the key."

Wang Wanzhi stopped Yan Yu: "Yan Yu, don't ask him for the key. I made the key myself. It's boring to have the key."

Yan Yu looked at the young lady's interested expression and wondered in her mind whether Xie Fu deliberately refused to give him the key.

It should be like this, he has so many tricks.

Oh, it's so good to see the young lady looking so excited, much better than looking depressed and lifeless.

Wang Wanzhi studied the keyhole with all her concentration, and said, "Yan Yu, go get some bamboo and a knife."

As night fell, the room was lit with lights, and Wang Wanzhi was studying under the lamp while dexterously carving the tooth-shaped keys.

She has made seven or eight keys in a row, but none of them can open the Luban lock. The keys must match perfectly, but if there is a slight difference, it will not open.

It was late at night, and Yan Yu yawned: "Miss, why don't you go to bed first and do it tomorrow."

"You go to sleep first."

Yan Yu said: "How about smashing it open with the hammer."

Wang Wanzhi glared at Yan Yu: "What's the point?"

Wang Wanzhi is immersed in this never-ending exploration and enjoys it.

Yan Yu was so sleepy that she slowly fell asleep on the table.

It was a quiet night, with only the flickering lights left, and it seemed like time was passing by.

Wang Wanzhi suddenly screamed in pain and immediately woke up Yan Yu. The young lady had a painful expression on her face and sweat suddenly broke out on her forehead.

"Yan Yu, I'm cold."

Yan Yu knew that the young lady was ill, so she hurriedly helped Wang Wanzhi to the warm jade bed and lit the two stoves beside the bed.

The red fire immediately made the room as hot as June, but Wang Wanzhi was still shivering from the cold, but the situation was much better than before.

At this moment, Yan Yu's warm clothes were covered with sweat, and she asked with concern: "Miss, are you feeling warmer?"

"Well, Yan Yu, bring me the Luban lock, knife and bamboo."

Yan Yu said helplessly: "Miss, why are you like a playful child who knows no restraint?"

Wang Wanzhi smiled sweetly: "Isn't this great?"

Yan Yu was stunned for a moment and responded quickly: "Okay, okay, I'm just worried about your health."

"It doesn't matter."

With concentration, Wang Wanzhi completely forgot about the cold pain. The human spirit is far higher than the physical body.

It took Wang Wanzhi a whole night to make an accurate key and unlock the Luban lock.

He smiled excitedly like a child: "It's solved!"

This sound woke Yan Yu up from his sleep, and he saw that the Luban Suo had turned into small pieces of wood.

This feeling of finally achieving the goal after going through all kinds of hardships made Yan Yu excited: "Where are the snacks?"

Wang Wanzhi held a small piece of paper rolled into a ball in her hand, and said with a sense of showing off: "Here it is."

Yan Yu looked confused.
