What happened?

Stark calmly walked out of the hole in the wall as he followed behind the trail of blood left behind by the man.

A chaos had ensued in the underground facility. Ethena's attack earlier had made all the sirens go off.

The shutters with enhancement formations immediately began to fall down and the entire facility had entered into a lockdown.

Stark knew that the man couldn't break through the barricades. There was no way for him to escape.

But, suddenly he realised that the area in which they were had an elevator. Things could be bad if that man decided to snuck through the elevator vent.

Even though there was a formation above, it would deactivate if someone was moving above.

Stark steps quickened and he immediately moved towards the Elevator.

When he got close towards the elevator, he heard a bang. The person was indeed planning on using the elevator vent. He broke through the closed door and entered the vent.
