Li Du had made the decision for a few reasons. One was based on morals. In secondary school, when he had learned that the conservation team leader had been shot by the poachers, he cried.
Every youth had once dreamt of being a hero.
Second, it was for their own safety. Although they did not have a good relationship with the rangers, those people were only protecting the environments and would not harm them.
It was different for the poachers. If they were to set up base there, it meant that Li Du and his people would be operating with a ticking bomb near them.
Now that the rangers were surrounding the protectors' camp, it was an opportunity to strike them all at once. Only by defeating those people for good they would be able to search for meteorites safely as long as they were on the island.
Besides, if they did not deal with the poachers, once they knew that Li Du's group had meteorites, they could possibly try to steal the rare stones.
