Introduction of Sirius Chen Yingtian;
According to Lei Zhan, he was an orphan and grew up in a welfare home. Proficient in many foreign languages, able to survive and fight in extremely bad situations. He once disappeared while carrying out peacekeeping missions abroad with other comrades-in-arms, but in fact he and his comrades-in-arms had a fierce conflict with the enemy. Sirius and Lei Zhan are in a crisis, and the enemy's gunfire is very fierce. Lei Zhan and others will be caught when they see it.
At this time, Sirius took the initiative to stand up and cover the retreat of his comrades. As a result, he was surrounded by the enemy. Sirius retreated while fighting, but the terrorists behind him chased after him, and Sirius was in crisis for a while. The enemy didn't want to kill Sirius, but wanted to capture Sirius. The enemy thought Sirius was a good man and wanted to capture each other alive, so they didn't shoot directly. Sirius was shot in the leg while running. Although he could not continue running, he continued to shoot at the enemy. Sirius was eventually outnumbered and fainted with injuries. After all kinds of nightmare torture, he was forced to join a terrorist organization.
Sirius is actually pretending to surrender, but he has always been in contact with the leaders of the military region. In fact, he was undercover in K2, an international terrorist organization, and later returned to the team. After the glorious martyrdom of Lei Zhan, Sirius took over the position of Lei Zhan.
