They had guns which were surprising to most people. Country Z was different from the other countries. They wouldn't allow anyone to carry firearms. However, these people not only had guns but had explosives as well.
If most of the guards at the Lawrence Institute weren't top-notch mercenaries, it would have caused even more damage.
The reason why they used such explosives at the Lawrence Institute was that they wanted to kidnap Di Yunxi's wife and son.
Because of the security cameras around and these men did not destroy any of these cameras while trying to kidnap them, everyone who watched the video was in shock when they saw how Ling Siqi and Di Qianchen got kidnapped.
If they weren't both smart and the child hadn't run out of the elevator at the very last minute, they would have successfully kidnapped both the young mistress of the Di family and the only grandson they had.
This was horrible.
