Super Invincible Battleship
Yan Fei ordered a small drone online, never expecting that the drone would suddenly become his avatar. Amazing, right? But what's even more incredible is that this drone avatar can actually upgrade, into a drone fighter jet, a heavy combat jet, a stealth bomber...... Are these powerful combat units really my avatars? Do they really expect me to take on the entire world? Yan Fei is utterly bewildered!
Chapter 339 Mechanical Sparrow_3
However, the mechanical sparrow was small and extremely agile, and under Yan Fei's control, it easily passed through the 200-meter-long narrow passage, then discovered a very spacious hemispherical cave on the other side.
The volume of this hemispherical cave was huge; the height was over 20 meters, and the radius was at least 50 meters. Moreover, the ground was surprisingly flat, able to accommodate hundreds of people moving around inside simultaneously. On the cliffs next to the hemispherical cave, there were also several passages leading in all directions, but it was unclear where these passages actually led.
Thanks to the communication capabilities of the global satellite system and the use of enhanced communication technology by the mechanical sparrow, even after it entered the belly of the mountain, Yan Fei could still connect to the mechanical sparrow through the satellite system and see the specific conditions inside.
