The spaceship turned towards another direction, and began to accelerate. Upon reaching lightspeed, it tore through space, entering into the dark universe.
The dark universe was a vast open space without any materials or objects. Hence, the spaceship could accelerate at an almost infinite speed. There wasn't any limitation.
The speed of the sixth grade spaceship which Luo Heng and Jiang Ming had boarded, had quickly been increased up to 300-times of lightspeed. Such was absolutely unbelievable. Moreover, it was very magical here. One mile here corresponded to 480 million miles outside.
"Wouldn't two spaceships collide head-on under such high speed? I think the collision would even kill a Golden Immortal!" Jiang Ming doubted.
