Dark Dragonlord

The System gave two methods.

The first: warm the egg with fire, seven days as the term. The fire must be a natural or magical source, something like Flame.

Luke had Flame, so that part wasn't hard.

The hard part was the time — seven days.

He already squandered so much time without even knowing the egg existed; how could he afford to wait any longer now?

The second method was instantaneous but thornier.

The second is Achieve Beast Exposure For Darkness.

Meaning the Beast must be steeped inside the field in question. Summoners commonly used fields like a Berserk field, an Intelligence-Boost Field, a Health field, even Aphrodisiac, which is a field.

All of them had their purpose for the beast.

For example, a Berserk field helps the beast go into a frenzy and increase attacks, while a Health field ensures constitution throughout a fight.

But the technique required a summoner with an A-Rank Soul to pull off.
