The first Space Gate that the Lin Feng team sealed was a Space Gate named Black Land.
This was a Seven-star Level Space Gate, and although its level wasn't very high, the reward was substantial, amounting to 2.5 billion.
Among the commissions accepted by the Lin Feng team, this price ranks third.
Such a high reward is due to the abundance of Black Earth Crystal within this Space Gate, which is a pitch-black mineral buried a hundred meters underground.
This mineral has high hardness and is widely used in industries.
The mineral can be used to manufacture weapons and is also important to the Alien Race, hence wars frequently occur at this Space Gate.
Initially, the Space Gate was crowded with conglomerates and major forces, frantically mining Black Earth Crystal 24 hours a day. However, the mining equipment frequently suffered sabotage by the Alien Race, and the miners were often assassinated. Finally, they were helplessly forced to give up due to the heavy losses.
