In this narrow passage of flesh and blood, Monica's extreme mutation strength is so strong that she is not afraid of them.

Mark is actually quite dangerous.

"Mum! (Leave it to Mum!)"

At this critical moment, Xiao Mu let out a confident cry!

Its dozens of tentacles that seemed soft and harmless instantly became as tough as alloy, and even grew mithril rock armor on them like a mountain of bone, leech and flesh.

No, that's not Rock Armor.

But it is purer mithril armor!

He truly is one of the most amazing members of the team, worthy of being the legendary magical creature – Lord Slime!

Mark was secretly amazed in his heart that Xiao Mu would master some strange skills from time to time.

He didn't even know how long Xiao Mu's skill bar would be after Monica successfully identified him!

While Mark was amazed in his heart, the simple Xiao Mu didn't think so much.

Facing several ferocious bone leeches rushing towards him, Xiao Mu did not retreat but advanced!

Its tentacles were like the most ingenious chains, wrapping around the middle of each leech's body with incredible precision.

The suction cups on the tentacles stuck firmly, and the powerful force instantly curbed the bone leech's momentum.

The large bone leech twisted and bit wildly, and the sharp bone spurs scraped against Xiao Mu's tentacles, making a harsh friction sound.

But it is difficult to truly break through that layer of mithril armor.

Xiao Mu uses the leeches' own twisting force to pull their bodies to entwine, cross, and flip with each other... The movements are as smooth as dancing.

In just a few breaths, several ferocious large bone leeches were forcibly tied into several dead knots that became tighter the more they struggled!

They bit each other, but could no longer pose a threat to Mark and Monica. They could only twist and scream in vain.
