Very confident?

In a company.

Adhi previously contacted someone named Henry.

Henry was a precaution that had been arranged by the Candra system.

The person who sent the money to Candra's account was Henry.

Apart from sending money, Henry also bought a McLaren 720S and a food island restaurant.

Henry bought it on Candra's behalf and gave it to Candra after getting a command from the system.

As for why Henry obeyed the orders of the system?

Adi doesn't know either.

Henry could have found a letter containing orders from the system in his parents' tomb.

Every time Candra gets a reward from the system, the letter will appear on Henry's parents' tomb.

The system could have given a reward to Henry after Henry carried out the system's orders.

Adhi tells Henry that Candra is in prison.

Adhi also explained to Henry why Candra could be in prison.
