Xiao Lintian and Commander Pang arranged the matter in the Empress Dowager's harem and rushed back to the temporary military camp of Guanjiabao.

Ling Yu is also back and is reassembling the ladder pulleys with the craftsmen. The assembly work is coming to an end.

This is reassembled to check where the problem occurs.

Xiao Lintian stepped forward, looked at it, frowned and asked, "Has any abnormality been found?"

Ling Yu rubbed his face hard and smiled bitterly, "No!"

"Xiao Lintian, it may be my design mistake, I did not consider the actual situation, and the calculation error... It's all my fault, please punish me!"

"Last time you made a mistake with An Zhe, I remembered the Ten Army Sticks! I will also get the Ten Army Sticks after the competition tomorrow!"

As soon as Ling Yu said this, An Zhe and Pei Yu next to him shouted: "No, how can you blame you! You don't want to do it either!"

Pei Yu said hurriedly: "The wheel you came up with for us is a great achievement. Although I lost the ladder competition, this kind of wheel can still be promoted in the future!"

Zhu De, the chief craftsman, is a man in his early thirties. He is a little short, but has a skillful hand.

He heard Pei Yu and the others' words next to him, and looked at Ling Yu and laughed: "General Pei is right. The wheels you think of, Princess Yi, can be used in many places!"

"Ordinary people have such wheels when pulling carts, saving time and effort!"

"Besides, you are a woman, how can you compare with a man? If you hit the ten army sticks, you will definitely be fragile..."

"Prince Yi, although the princess' pulley is wrong, the design wheel is successful, so let's make up for it!"

Xiao Lintian was a little irritated. He couldn't find the problem and didn't find the traitor. Then there might be mistakes in the key game tomorrow.

"You keep checking, you must figure it out!"

Xiao Lintian saw that some craftsmen were sweating all over when they saw that Ling Yu was there. It was difficult for them to take off their clothes and work, so he pulled Ling Yu out.

Pei Yu and An Zhe were also sweating profusely, so they came out to have a breath of wind together.

The four of them walked far away, and Pei Yu looked at Ling Yu: "Sister Ling Ling, you can't find nothing!"

"You designed the pulley. We tested it a few times before, but it was fine. How could there be problems with the competition?"

Xiao Lintian looked at Ling Yu as soon as he heard this and whispered: "Did you notice something strange? You said you didn't notice it just now, but you just didn't want to arouse the alertness of the traitor?"

Xiao Lintian thought of Bai Cui, and Ling Yu was careful and must have discovered the suspicious thing that Pei Yu and the others did not find!

Seeing that these two people were so keen, Ling Yu nodded with a smile.

"I did find something wrong!"

"Tell me quickly, I checked with you just now, why didn't I find anything?" An Zhe asked.

"The lifting pulley is composed of countless pulleys installed on the bearings. I have checked all these pulleys and found no abnormalities. However, there is a piece of pulley with grease. Although it is covered with grease, the friction marks of the pulleys on it are very shallow!"

Ling Yu smiled coldly: "Such heavy ladder is transported up by pulleys, and the friction is very strong!"

"Pei Yu, Anzhe, you should see the deep marks rubbed from other bearing belts! Why is the trace of the section I checked very shallow?"

"There is only one answer, this bearing belt has never been transported to the ladder!"

"But why does it appear here!"

After hearing this, Xiao Lintian responded quickly and answered: "This should be replaced afterwards!"

"There was a problem with the lift pulley at that time. As soon as you check it, you will know that someone was touching it, and we can catch the one who touched it!"

"But if he changed the bearing belt, we might not be able to doubt him!"

Who would be the traitor who participated in the assembly of the ladder?
