It opened its enormous mouth, revealing a complex gear structure, and a cluster of fluorescent blue light flickered within its mouth.

Then.

It spread out suddenly.

Buzz!!

The three main damage-dealing towers were once again the first to be hit.

[Warning: The Wind Cannon Turret has been hit by the Boss Monster's Magnetic Shock and is now in a frozen state! Duration: 9 seconds!]

[Warning: The Fire Demon Tower has been hit by a magnetic shockwave attack from the boss monster and is now in a frozen state! Duration: 9 seconds!]

[Warning: The Aoki Tower has been hit by the boss's magnetic shockwave attack and is now in a frozen state! Duration: 9 seconds!]

...

Su Bai subconsciously raised his arm.

"strangeness..."

He muttered to himself.

The leader monster's primary target was clearly him, but the strange sonic waves that swept over him had no effect whatsoever.

It was only then that the attack hit the defensive tower behind him.

This situation is different from the boss monster in the fifth wave, whose skills could even affect the lightning hand it summoned.

"This boss monster's silence skill should only affect defensive towers."

Su Bai realized what was happening.

A tree without roots!

He first summoned the Rootless Tree to attract the boss monster's aggro.

Then look at the other party's attributes.

[Ancestral Mask: Leader, Level 20, Health: /, Special Skill: Magnetic Oscillation (Affects buildings in a small area, stopping them from functioning for 10 seconds, 30-second cooldown)]

...

The level 20 boss monster is exactly the maximum level that is stuck in the first tier.

It is only one level different from the second order.

However, it was this one-level difference that made Su Bai breathe a sigh of relief.

He waved slightly to the Templars.

Simply signal them to oversee the battle.

A level 31 Templar Knight will not gain any experience from killing monsters ten levels lower than himself. If they join the battle, they will only take away all of Su Bai's experience.
