The height of Tyra's high-end lab was around a hundred meters, and considering the underwater cavern that just appeared, the total length was probably no more than two hundred meters.
The goal of Shen Congfei's mission was to reach the bottom of this cavern.
Just now, according to the explorer's "Survival Skills", he got the chance to exploit the security system of this place.
It was located at the bottom of the cavern.
However, the current deep dive was not the most threatening aspect.
The main concern was the sea dragon that resided in the cavern.
Once he entered the water, he immediately activated the "Extreme Sport" skill.
As the explorer's third ability, this skill covered a wide range of activities.
Extreme diving was indeed a type of extreme sport.
Not to mention being in the same room with a sea dragon was already extreme enough.
After entering the water, he listened to the external armor's intelligent system constantly reporting the submerging depth.
