Sam and his friends are on a return journey.
It has been almost three months since they started their journey and it will take around a week for them to return.
This time, he did gain something. Even though, his friends didn't have much to do in this journey. It would have been difficult without them.
They destroyed a decent amount of formations to the point that it would be almost impossible for him to take the whole island without them.
He also understood now, why it is so difficult, if it is just like what that guardian said, then hundreds of people will be sent to the island and the formations would be cleared faster than normal. That is why it was too much for just four of them.
As for what to do with the guardian and handing the pillar over to the people in higher realms he has his own plans for that.
After a week, Sam is back in the city.
