How did Tian Yong, who fell in love with special forces, send a message?

My dear guardian, Tian Yong, sends messages in Morse code. Tian Yong and Liang Muze are special forces, so they have received professional password training. When Tian Yong was undercover in a criminal gang, he used Morse code to send messages. After the information came out, Liang Muze cracked it again and got a lot of valuable information. Regrettably, Tian Yong later revealed his identity as a policeman and died.

Tian Yong was chosen to carry out this potential task because he once worked in a bar. At the beginning, all the movements went smoothly. Because criminals put interests first, what happens in action becomes logical. In fact, Tian Yong revealed his identity when he first met his master.

A wily old master saw at a glance that Tian Yong was not an ordinary slave. Although Tian Yong did a lot of actions to hide his identity, on the surface, he didn't seem to give away the clues, but all this seems to be a clown in his eyes. Because Tian Yong had already been betrayed by Zhuoran, and Zhuoran's motive of betraying Tian Yong was to let his mother get a heart.

Tian Yong knows that this task is not as simple as going deep into the lion's den, and he is likely to die here, but he is still willing to sacrifice his life for the success of the final operation. Tian Yong signed an agreement to donate organs a long time ago. It is for this reason that Zhuoran betrayed Tian Yong, and Tian Yong's heart was later placed in Zhuoran's mother's body.
