After separating from Professor Shen Wu, Yang Tian was about to leave when Solly walked over.
“Yang Tian, What’s the number of your instant communication device?”Solly stared into Yang Tian’s eyes and asked directly.
Instant communication device?
Yang Tian was stunned. Only then did he remember that he had bought an instant communication device the last time he left for training.
He remembered that at that time, seven light rain, seven color sisters, and seven light Hao had asked the same question.
On Earth, this kind of instant communication device was a communication tool like a mobile phone.
Yang Tian immediately took it out from his storage bracelet.
It was a small cylindrical particle-like object that was only five millimeters in diameter. Its surface was covered with furry yellow fibers.
After Yang Tian took them out, he immediately stuffed them into his ears.
