Reincarnated as a Mosquito, the School Beauty I Sucked to Tears is a Reborn Empress

Chu Sheng looked at the remaining 170-plus million Life Essence and had to temporarily abandon the idea of upgrading the Golden Silkworm King Gu.

”System, upgrade all the Spirit-Devouring Worms first.”

[Ding! All Spirit-Devouring Worms have been upgraded to Eighth-Grade.]

[Ding! All Spirit-Devouring Worms have been upgraded to Ninth Grade.]

[Ding! Upgrade failed. Unable to continue upgrading the Spirit-Devouring Worms.]

’What’s going on?’

Chu Sheng was stunned for a moment, thinking he had run out of Life Essence.

But a closer look revealed he still had over 150 million Life Essence, which was more than enough!

”System, why did the upgrade fail?”

[Spirit-Devouring Worms are a eusocial species. There is an upper limit to the colony’s level progression. A King Realm Spirit-Devouring Mother Worm is required as the colony’s core to continue upgrading their level.]

’Eusocial?’

Chu Sheng thought about it for a moment. It was probably a social structure like that of ants or bees, where a mother worm leads the colony.

He suddenly recalled that when he first got these Spirit-Devouring Worms from Sui Ming Province, there had indeed been a Spirit-Devouring Mother Worm.

That Spirit-Devouring Mother Worm was only Second-Grade, yet it had thrown the entire Sui Ming Province into turmoil.

It just went to show how rare and powerful a Spirit-Devouring Mother Worm was.

’Where am I supposed to find a King Realm Spirit-Devouring Mother Worm!’

’I finally scraped together some Life Essence, and now I can’t even upgrade anything? What a rip-off!’

[Ding! You can fuse all existing Spirit-Devouring Worms and consume an additional 100,000,000 Life Essence to evolve one King Realm Spirit-Devouring Mother Worm.]

Chu Sheng hadn’t expected the system to offer a solution so quickly.

”What abilities does a King Realm Spirit-Devouring Mother Worm have?”

[A King Realm Spirit-Devouring Mother Worm can produce Ninth Grade Spirit-Devouring Worms.]

”What about an Emperor Realm Spirit-Devouring Mother Worm?”

[An Emperor Realm Spirit-Devouring Mother Worm can produce King Realm Spirit-Devouring Worms.]

He drew a sharp breath.

An assembly line churning out King Realm Spirit-Devouring Worms...

This was insane!!!

”Then what are you waiting for?! Upgrade it!!!”

[Ding! Fusing Spirit-Devouring Worms. Consuming 100,000,000 Life Essence...]

[Ding! King Realm Spirit-Devouring Mother Worm evolution successful!]

Chu Sheng couldn’t wait to check the Spirit-Devouring Mother Worm’s stats.

[Spirit-Devouring Mother Worm (King Realm): Has no Combat Ability. Can produce 1 Ninth Grade Spirit-Devouring Worm per minute.]

One per minute, that’s 1,440 a day, and 144,000 in a hundred days!

Chu Sheng was instantly excited. This was so worth it!

Even though it cost one hundred million Life Essence, he would never have to worry about not having enough Spirit-Devouring Worms again.

Being able to endlessly produce Spirit-Devouring Worms... he’d hit the jackpot!

”System, continue upgrading the Spirit-Devouring Mother Worm’s level!” Chu Sheng gave the order immediately, without the slightest hesitation.

[Ding! Spirit-Devouring Mother Worm upgraded to Emperor Realm.]

[Ding! Spirit-Devouring Mother Worm upgraded to Life and Death Realm, First Layer.]

[Ding! Insufficient Life Essence. Unable to continue upgrading the Spirit-Devouring Mother Worm.]

Chu Sheng quickly checked the Spirit-Devouring Mother Worm’s stats again, the excitement in his eyes growing even more intense.

[Spirit-Devouring Mother Worm (Life and Death Realm, First Layer): Has no Combat Ability. Can produce 3 King Realm Spirit-Devouring Worms per day, or 3,000 Ninth Grade Spirit-Devouring Worms. Production type can be set by the Host.]

”King Realm! Definitely King Realm!” Chu Sheng decided without a second thought.

Although the difference in quantity was heaven and earth, there was simply no comparison between 3 King Realm worms and 3,000 Ninth Grade ones.

But in terms of quality, the difference was also heaven and earth!

A thousand Ninth Grade Spirit-Devouring Worms could never defeat a single King Realm Spirit-Devouring Worm!

The gulf between Ninth Grade and King Realm was an incredibly difficult one to cross!

Chu Sheng looked at his Life Essence, now wiped clean on the panel, and couldn’t help but click his mouthparts.

Three hundred million Life Essence, gone before he could even get used to having it. It really didn’t last long.

But thankfully, the rewards were also substantial.
