There was no emotional fluctuation and the attitude was mild from beginning to end. It can be maintained even under his authority, which illustrates the problem.

After divinity detection in the past, Lin Fan found out that the security guard was different.

It's not a human being, but a machine. AI has been added with various elements. The language just now is just a good match in advance. To be precise, it has been input in advance.

"I'm really curious that the Li family has output in this respect."

Looking at the monitor head on the wall, Lin Fan's mouth curved: "OK, take me to your R & D room and visit your fruitful achievements."

"Yes, this way, please."

As if given the order, the security guard stood up straight and then turned around to lead the way. After going through a long passage, I finally came to a very big room.

At first glance, a room of about 200 square meters is empty. But if you look closely, you will find that there are small visible lines on the walls around.

Through these lines, we can find clues. The walls around the room are hidden. The whole room has been transformed into an intelligent one, which can be guaranteed that it is still under monitoring.

"Mr. Lin, please wait a moment. Our professor will meet you later." The security guard who put it down turned away.

Click, click.

Two voices suddenly sounded, and the opposite wall burst out. As the wall slowly rotated over, Li Yuanfeng in a white coat came into view.

"Lin fan, welcome to our R & D room."

Putting down his red wine cup, Li Yuanfeng opened his hands and motioned: "how do you feel? Are you satisfied with our R & D room? "

"What are your R & D achievements?"

Looking at Li Yuanfeng, Lin Fan joked, "bring me to your R & D room, and you won't just want to share your achievements with me?"

Ha ha ha ha ha

Li Yuanfeng angtian laugh, so easy to pit Lin Fan down the R & D room, this is his unexpected. According to his plan, how could he succeed at a lot of costs.

It doesn't take any effort to come now. It seems that God is helping the Li family get rid of this disaster.

"Lin fan, I can only say that you are too careless. You are so easy to get down to the seventh floor underground."

Slowly down from the platform, Li Yuanfeng's face was full of cold: "I told you before, offended our Li family, you are not far away from death, and today our research and development results will make you die very comfortable."

"Of course, I'd love to show you our R & D results."

He raised his hand and snapped his finger. Li Yuanfeng's voice echoed in the room: "show time."

Boom, boom.

Bursts of heavy metal switching sound, four walls have changed. On the one hand, there are cold weapons and hot weapons; on the other hand, a challenge arena is highlighted; on the other hand, a door appears.

Above the ceiling, a glass cover slowly descends to cover the position of the challenge arena.

"Lin fan, our Li family can be called the first of the four big families in Zhonghang City, but it's not a real name."

He reached out and knocked down the glass cover. Li Yuanfeng tutted: "listen to this sound. This kind of glass is the result of our research. In today's world, it can be said that the thickness is the best and the endurance is the strongest. No matter how you make it, it will not break."

"You Li family sell glass?"

Hearing the dull percussion sound, Lin Fan didn't understand: "so what you want to brag about with me is the glass made by your Li family?"
