<Growth Guideline unlocked for Dungeon: Compulsory task or Simple Task>

<Consume the devil to grow in strength>.

Lenny had just killed the devil when he got this alert from the Satan system.

This made him smile.

He walked up to the devil's corpse, and before the eyes of everyone watching, he used his blade to open the devil's chest.

"What is he trying to do?" This person in the Arena inquired subtly.

Many of them even looked at Cuban, expecting an explanation.

After all, he was Lenny's Arena master.

However, what happened next was something no one expected.

Lenny opened the chest of the devil.

He dug out its heart, which Lenny was sure was its heart.

Although it was square-shaped and did not at all look like a heart, Lenny could instinctively tell from his experience that this was it.

He raised the heart above his face, and then he squeezed tightly.
