Li Yun listened to Tian Jibaishi's honest words, and his heart became more determined, what he wanted was this kind of authorization.

"Professor, without further ado, let's start the action today, there is only one elective class until four o'clock in the afternoon, and we should be able to figure out the way." Li Yun said.

"It's better to be young! When you want to do it, there is absolutely no ambiguity, okay, it's going to rain, and the mother is going to get married, whatever you want, what special help do you need, call me, this old man. Tian Jibai said with a smile on his face.

After saying goodbye to Tian Jibai, Li Yun held the double-headed key in his hand, and the USB flash drive watched Tian Jibai's sturdy figure leave, and secretly made up his mind.

Bi Sheng watched Tian Jibai's figure leave, and then said to Li Yun: "Boss Yun, what you are holding in your hand is the Tianyan system!" I don't know how powerful this thing is. ”

Li Yun tilted his head and looked at Bi Sheng and said: "It can be called the Sky Eye System, which means that this thing can monitor any corner, as long as the satellite signal exists, any device with a shooting function can become an eye, and carry out all-round monitoring without dead ends. ”

Bi Sheng listened to Li Yun and wanted to look at the sky?
