Chapter 621: Professional protection mechanism canceled! Competitive dungeon!

The parcel opened, revealing two white translucent round stones.

【Spirit Stone S1 (Tool)】

【Quality: S-tier】

【Introduction: Produced from the final boss of the Lookout (Purgatory-tier), it is one of the core materials for manufacturing Spirit Rings; it can also be used to contract living beings, allowing them to learn a skill book.】

【Restriction: For each contracted creature, the S1 series Spirit Stone can only be used once.】

"Series tool? S1?"

Li Yao said in surprise,

a flash of pleasant surprise in his eyes.

Letting a summoned beast learn a professional's skill book

is inherently an act of defying heaven and changing fate!

He had originally prepared himself

for the idea that one Chess Piece could only learn one skill book!

If there is S1,

there must be S2!

As long as he finds the drop location for the S2 series Spirit Stones,

he can let the Chess Pieces continue to improve!

As for S1,

there is currently a way to collect them.

Li Yao lay on the bed, closing his eyes and pondering.

Gainyatt will use that 【Surface Skin Vitality】 book

to continue enhancing its sustained output capability.

The Devourer needs a taunt skill.

Kha'Zix has 【Practical Training】, so it needs a large-area physical group damage skill.

The Azure Bird and the Immortal Thunder Mouse are positioned as support,

so it's best if they have life-saving skills.

As for that Tiger Armor guy,

it should get a status skill of the "nourish war with war" type!

Displacement skills aren't out of the question either.

Pondering,

Li Yao drifted into dreamland.

The next day,

【Jianyan Earth Cave】 still opens at ten o'clock in the morning.

Li Yao rarely slept in.

At nine-thirty, he reached the dungeon room.
