Chương 424: Problem.

Early morning, Yang Dao pushed the trolley carrying the aircraft model out of the lab. The employees have yet to arrive. He had only finished the final touches last night. So he decided to get things done with not much noise. RALF bot has been standing by at the door of the lab for three months now. 

Yang Dao said as he came out of the lab, "RALF, help me set up the air tunnel." 

The bot nodded and said, "Yes, Master."

Yang Dao had been very careful when designing the AI program code. He was aware that human beings are driven by their emotions, and these emotions, if not controlled properly will cause things to go into disarray. Thus, he made it so that RALF would understand emotions but never develop some of his own. 

The bot took the lead to push the trolley from the lab to the elevator. They descended two floors, accessed the skywalk, and came to Dao Technologies buildings. They made their way to the Air Tunnel and began to prepare for the test.
