After he arrived at the island, Shen lang did not rush to go underground. Instead, he observed from above.
It had been more than a month and a half since the Black Death bomb was launched, so all the viruses on the island had been wiped out.
To a certain extent, this Island was very similar to Shen Lang's Nirvana Island. It was surrounded by dense forests, and there was no dock. From the outside, it was impossible to tell that there was a secret base inside.
Moreover, the island was surrounded by submerged reefs, and ships that were slightly deeper in the water could not get close to it.
If it weren't for the hot air balloon, they wouldn't have found the secret base on the island. Even if they found it by accident, they wouldn't be able to attack it. They would be dead before they even got close.
