Chapter 417: Promotion to

5,000 laser towers,

how does one reach the Star-Explosion tier?

Very simple.

No need for so many complicated effects.

Relying solely on the Twin Sacred Tifa Flower will do.

Su Yu's territory buildings now exceed 80,000 in number,

and under the effect of the Twin Sacred Tifa Flower,

their base attributes have grown by more than eight hundred times.

The Legendary laser tower, Hong Lin,

though only level 10,

has a base attack power of 80, which under the amplification reaches over 60,000.

Over 60,000 attack power,

though high, when converted into combat power,

is still far too short of the Star-Explosion tier's 6,048,000 combat power.

And what allows her to reach that tier,

even surpass it,

is thanks to the laser tower's special effect.

"Laser Beam Convergence": All laser towers within joint range can launch a sustained concentrated beam attack; for every laser tower within range, attack power increases by 1% (10x efficacy), attack range (radius thickness) doubles (10x efficacy), and range increases by 1% (10x efficacy).

Su Yu's pace of collecting KBBF crystals has never slowed.

The territory's laser towers have grown from the previous 2,100 to 5,000.

5,000 laser towers,

then activating "Laser Beam Convergence"…

Under the 10x amplification of the Twin Sacred Tifa Flower's "Sacred Tifa Blessing,"

attack power can increase by 5,000%!

An attack power of 65,760, multiplied by another 50 times,

comes to 3,945,600 attack power!

Nearly 4 million attack power, in one stroke, approaches the Star-Explosion tier!!

What's even more terrifying is that Su Yu insists on a one-shot kill,

and has also used a Legendary-grade item.

A one-time-use Legendary item — 【Overload Firepower】,

this is war spoils transmitted back from when Yeliya Na once crushed a Celestial Bone Tomb outpost,

war spoils transmitted back.

It can be used on tech-type defense towers of Legendary grade or below, and level 20 or below.

It disappears after one use,

able to temporarily boost that defense tower's next attack,

raising this attack's attack power to 20 times!

The 20x boost only applies to buildings of level 20 or below and Legendary grade or below,

it looks very powerful, but it's also quite ordinary,

after all, it's one-time-use, and the attack effect only lasts for one strike.

However…

If combined with Su Yu's buildings,
