Although the speed of the three-way bus, which is connected by two carriages, is not fast, because there are not many cars on the road, there will be no traffic jams like in the previous life, so the Sixth Military Medical University and the Sixth People's Liberation Army Information Engineering University soon disappeared in front of Zihan.

The sun had already risen in the sky, and just as the tall and low buildings were about to turn into low courtyards, the bus, which had been going south, turned around and headed east.

After about twenty minutes of driving, a large courtyard surrounded by a high wall and bordered by a mountain range at the southern end of the road appeared on the left.

"Taifeng Pharmaceutical Factory has arrived, and those who want to get off the bus should get off quickly."

Amid the repeated announcements of the conductor, the bus stopped in front of the Taifeng Pharmaceutical Factory, which was estimated to be at least one or two hundred acres.

Grandpa Lin and Zihan stepped off the bus.

The two-fold steel fence door was locked together with iron chains, and there were two other small doors on either side for people to enter and exit.

There is a hut on the inside of the small door on the left, which is supposed to be the guard's duty room.

Grandpa Lin took Zihan to the small door on the left, held the big lock that locked the small door, and hit the door frame of the small door a few times.

The door to the duty room opened, and out came a man of about fifty years old in gray overalls.

As soon as he saw Grandpa Lin, the man's already somewhat unhappy face immediately put on a familiar smile.

"Dr. Lin, you're here."

The man quickened his pace and opened the large lock with the key hanging from his waist.

Grandpa Lin politely thanked the man first, and then walked in with Zihan.

"Xiao Zhang, please ask, is Director Lei in the factory?"

Zhang Youda locked the door and looked at Grandpa Lin with a humble face, "Doctor Lin, you are too polite, Director Lei is in the factory!" ”

"Then please call him and ask to see when he is free, can I meet him today?"

"Doctor Lin, Director Lei has ordered, you can just go to him when you come."

Zhang Youda's brows furrowed almost invisibly, why is this old man so stubborn every time, Director Lei is so good to him, can he use it like this?

"He's a busy man, so it's better to say it."

The corners of Grandpa Lin's mouth curved, pretending not to feel Zhang Youda's impatience.

Zihan took his grandfather's arm and followed his grandfather into the duty room.

Although Zhang Youda was reluctant, he still dialed the phone.

"What are you talking about, Dr. Lin is here?"

Zhang Youda patiently reported to Director Lei on the other end of the phone that Grandpa Lin was coming, and there was an exclamation on the phone that seemed to be a little surprised and a little loud.

"Quick, get him to my office."

After that, the phone on the other end had already hung up.

Zihan turned his head to look at his grandfather, and his grandfather happened to look over.

Seeing the search in Zihan's eyes, Grandpa just smiled and nodded at her.

Director Lei's surprise words made Zhang Youda stunned for a moment, and then immediately put a more humble smile on his face.

"Dr. Lin, give me your backpack, and I'll send you over."

Grandpa Lin and Zihan had already stood up.

"No, I'm familiar with it, just go over by yourself, you still have to be on duty!"

Grandpa Lin avoided Zhang Youda's outstretched hand, winked at Zihan, and then walked towards the door.

The smile on Zhang Youda's face froze, and then he hurriedly followed behind Grandpa Lin and walked out of the hut.

His eyes turned to look at the door, as if he hesitated for a moment, and then turned around and quickly followed Grandpa Lin and Zihan, who had already walked a few steps.

At this time, he had no patience at all, and tried his best to find a suitable topic to chat with Grandpa Lin.
