Zhang Bin's business is very good. When there are many orders, Li Fengmei will take a few children to the yard to help deliver goods and do some tricks.

At present, the business is just starting, and the Zhang family is completely enough.

Seeing that there are dozens of dollars in income every day, the smile on the Zhang family's face has never stopped. The days used to be in a daze, and it really counts every day. But now I finally see hope and have hope.

Therefore, everyone in the Zhang family is energetic and energetic, and their entire mental outlook is very different from before.

For a time, everything was moving in a good direction.

However, at this moment, a big problem occurred in Qi Han’s project!

"What's going on? Didn't that batch of building materials be fine yesterday? Why did they disappear this morning? You guys make it clear."

The chief foreman scolded the workers with a pale face.

"General engineer, we don't know what's going on. We saw building materials piled up there while we were patrolling last night. But I didn't know that when we woke up this morning, we disappeared."

One of the middle-aged men explained with a stern face. They also felt very wronged and even more evil. Why did such a large number of building materials suddenly disappear?

"I just want to know the reason and don't want to listen to your nonsense. You were on duty last night. I won't look for you, who will I ask for?"

The chief foreman was about to explode, but they finally introduced the building materials from the capital. Shu Province currently does not have the production technology for steelmaking and ironmaking, and all steel needs to be approved from the capital.

For this bridge construction project, the batch of steel that has been produced has been saved by a lot of effort and effort. It can be said that it is one of the more important building materials in this project.

It’s not that it is expensive. Of course, if it is too expensive, it will not save money to build the bridge. It is mainly because the production volume of building materials is relatively limited and it takes time to make it in batches.

As a result, such an important building material disappeared when it is gone. How annoying is it.

Qi Han, who was standing beside him, asked, "You said that in the middle of the night, I saw building materials piled up in place last night. You fell asleep in the second half of the night. The building materials disappeared after waking up at dawn, right?"

"Yes, yes, that's it. We didn't mean it, and we didn't know why. We felt particularly sleepy last night. We thought I was asleep and there were other people guarding me, but they couldn't help it and fell asleep as well."

The on-duty coworkers looked ashamed and lowered their heads and did not dare to face the chief engineer. No matter what the reason was, they had neglected their duties.

They also realized the seriousness of this matter. They probably could not afford the cost of the building materials even if they sold them.

"Have you eaten or drunk anything before you dozed off?" Qi Han asked in a deep voice.

He couldn't stand by and watch this matter. If he really wanted to pursue it, he was responsible, because this batch of building materials was signed by him.

When the batch of building materials was delivered to the construction site yesterday, the other person in charge of the construction site happened to be there. If no one signed the acceptance, the truck master would not dare to ship the goods casually.

There was no choice but Qi Han, as the chief designer of the project, had to sign for it.

But I happened to be so coincidental that the building materials that arrived only in the afternoon suddenly disappeared in the second half of the night.

There was a hint of coldness on Qi Han's lips. He didn't believe such a coincidence. All the traces were just humans.

Hearing Qi Han’s question, several workers on duty on the night shift looked at each other and looked at each other.

"I ate the food from the small cafeteria at night, uh...If there is any other thing, we all drank some camellia to cheer up and we made some wild tea on the mountain or herbs made of soaked water. Many people on the construction site drank it, and there was nothing else."

The head of the on-duty team carefully recalled what everyone had eaten and drunk last night and answered truthfully.

Generally, they are on night shifts, and they are not infected with any alcoholic things, for fear of affecting the duty. But I don’t know why, I was particularly sleepy last night, but I didn’t know that after all I didn’t pay attention, everyone fell asleep.

"Yes, we just drank some camellia." Several others responded.

Qi Han pondered, "All you guys have ever drunk camellia tea? Then can't you show me the camellia tea you made?"

Seeing this, the foreman beside him was a little confused and couldn't help but walk to Qi Han's side and whispered, "Xiao Qi, have you discovered something?"

"It's hard to say now, I'll find out first." Qi Han replied conservatively.

Soon, several on-duty workers brought their camellia bags and their teacups together.

"Designer Qi, everything is here."

"Thanks."

Qi Han took it over and looked at the workers around him who were joining the fun, "Do you drink the same camellia as theirs? Did anyone drink the camellia before going to bed last night?"

"Yes, we bought the same camellia from the same house, and we fried it at Huang Daniu from our construction site."

"Yes, yes, we've been drinking for more than half a month."

"Comrade Qi, I drank it last night."

“I have drunk it, too.”

Qi Han walked to two workers who also drank camellia last night, "How long did you fall asleep after drinking camellia last night? Do you feel particularly sleepy?"

One of the middle-aged men responded, "I didn't drink tea before going to bed last night. I felt thirsty in the middle of sleep, so I got up and drank most of the teacup of water, and then went to bed."

"I drank a cup after supper last night, but I didn't feel sleepy after that. Instead, I felt that I had drunk too much tea and was a little excited. I lay in the bed for more than an hour before falling asleep."

Another worker who said he had also drank tea last night also truthfully told his experience last night.

When the head of the on-duty team heard this, his mind turned around and he immediately understood. He couldn't help but look at Qi Han excitedly.

"Designer Qi, is there any problem with the camellia we drink?"

"There must be a problem. If I hadn't said that, I wouldn't have thought that last night's sleepiness was really too dizzy, as if it was completely out of control."

"Yes, we obviously made up for the sleep during the day, why are we still so sleepy?"

"Even if I dozed up last night, I felt that I was too sleepy until dawn. Logically, if someone went to the construction site to carry steel, there would definitely be some movement, but we did not wake up at all."

"It makes sense, unless the steel disappears in place, it should be a little loud."

For a moment, several workers on night shifts were talking and actively expressed their doubts.

After all, what else can't be understood?

The building materials disappeared and were stolen by someone!
