Lin Chen also suddenly realized, since he could use modern tactics, he could also use modern scientific knowledge.
"Seems I've been here too long; my brain's gotten a bit rusty." Lin Chen patted his head, his pupils lighting up at that moment.
In the current situation, the number of demon beasts was too overwhelming; even if these people gave their all, they couldn't possibly succeed.
However, it wasn't without a solution.
Lin Chen thought quickly: to solve them, there was only explosives.
If this place had a great demon annihilation formation, it must've been activated in history.
So there must be a lot of demon beast remains buried underground here, which, from a scientific perspective, would turn into coal or oil over time.
However, without instruments, how could Lin Chen know where coal was hidden underground?
This was the problem troubling Lin Chen.
"Calm down..."
Lin Chen took a deep breath.
"This might have been a battleground of the races long ago....."
