Starting with summoning the succubus

You have killed an Ivicent Leinster Bug (Tier 0), experience +1.

……

In the brightly lit biological laboratory, Qi Lin squatted next to the culture soil, holding tweezers, continuously removing insect eggs from the queen's body, then popping them, and throwing the dead eggs into the recycling bin next to him.

The entire movement was performed in one smooth motion.

Because he has repeated it almost three hundred times.

What does "killing monsters" mean?

This is called monster farming!

Qi Lin's experience points skyrocketed during this process!

until……

You have killed an Ivicent Leinster Bug (Tier 0), experience +1.

Experience points: 300/300

[You are now ready to upgrade!]

"upgrade."

Upgrade successful!

Remaining attribute points: 1

-

Experience points: 0/400

-

"Add this 1 attribute point to [Spirit]."

[Spirit: 7 stars → 8 stars]

"Uh?!"

Qi Lin immediately felt a throbbing pain in his head.

But this feeling was fleeting, replaced by an indescribable sense of refreshment!

A familiar process.

This is the feeling of increased mental strength!

Spiritual power is important because it is also known as the "soul".

It's not just mages who need strong mental power; warriors do too.

For a mage, the higher their mental strength, the easier it is to learn and cast spells.

For a warrior, the higher their mental strength, the faster their combat awareness, and the better they can perform in actual combat. After all, the physical body is just a shell, while the spirit is the core.

Unfortunately, Qi Lin is a demon messenger.

At the zeroth level, a demon wielder has no magic power and a weak physical body. Improving their mental strength does not bring about any substantial changes; at most, it makes them a little smarter and makes reading and studying easier.

However, things will be completely different once you advance to the next rank.

When a demon wielder's mental power reaches level 0, star 9, they can summon a second demon and thus decide their future development direction.

Is it a specialization in physical combat?

Or should I specialize in magic as a mage?

Or perhaps a more balanced approach to magic and martial arts?

All of this depends on which direction the demon summoned a second time will be inclined towards.

If the first demon summoned by the demon wielder is a friend or a partner...

So, the second demon they summoned was food and resources!

Because the Demon Envoy needs to personally kill the second demon summoned, and with the help of the first demon companion, absorb the demonic power of the second demon and integrate it into his own body, thereby completing a transformation in his life level and officially stepping into the realm of a first-order extraordinary life!

Devouring a demon is the way for a demon wielder to advance to the next rank!

"almost."

Qi Lin glanced at the system panel and the glowing insects that were still multiplying, and his eyes gradually lit up.

I'm still 400 experience points short.

It can be done tonight!

"Smack!"

Qi Lin extended his tweezers and popped another insect egg.

You have killed an Ivicent Leinster Bug (Tier 0), experience +1.

Experience points: 1/400

Keep grinding!

……

……

Time passed little by little.

Qi Lin continued killing the insects, and finally, just a few minutes before the queen stopped laying eggs, he successfully collected all the experience points needed to upgrade.

Experience points: 400/400

[You are now ready to upgrade!]

"Hmm, it should be fine."

Qi Lin glanced at the large number of insect eggs in the recycling bin and pondered for a moment.

He killed nearly 700 larvae tonight, while the queen only laid a little over 900 eggs from start to finish. He didn't know why it was less than the standard number. Ye Sen had previously said that the queen could lay thousands of eggs in one night.

Ye Sen also said that seven out of ten insect eggs should be removed.

However, seeing that his experience bar was almost full, Qi Lin simply killed a dozen more.

The excess percentage isn't too high, so Ye Sen probably won't pursue it.

"upgrade."

Upgrade successful!

Remaining attribute points: 1

-

Experience points: 0/500

-

"Add this 1 attribute point to [Spirit]."

[Spirit: 8 stars → 9 stars]

"Ok!"

Qi Lin groaned as the familiar throbbing pain in his brain returned, but after enduring it, the feeling of refreshment returned as expected.

Mental strength has been enhanced once again!

Tier 0, 9 stars!

Alright, he's ready to summon the second demon!

But there's no need to rush.

According to school rules, while demon wielders can attempt to advance on their own, it is recommended that they do so under the protection of a teacher.

He could have waited until tomorrow to ask his homeroom teacher, Feng Shaoyuan, for help.

"Let's go back to the dorm first and talk about it then."

Qi Lin packed up his tools, turned off the lab lights, locked the door, and left.

In the darkness, the soil was filled with flickering blue fluorescence.

The location of the Queen of the Noctiluca was emitting a different, faint red light, which vanished in an instant...

……

……

The night was still and quiet, the moonlight as smooth as water.

Qi Lin walked along the empty campus path towards the dormitory building.

This return route was different from the route he came by. He had originally planned to take a different route and enjoy the campus scenery along this path.

But it was precisely this decision that led him to meet an unexpected person on the road.

He was a tall, two-meter-tall white youth, covered in sweat. He was holding a heavy sword for practice in his left hand, wearing athletic shorts and shirtless, revealing extremely strong muscle lines. His eight-pack abs were clearly defined, and the sweat made his muscles look even more rugged and handsome.

The vest and towel, already soaked with sweat, were draped over his shoulders.

Gordon David.

"..."

Qi Lin and he met unexpectedly, and both stopped ten meters apart.

"What a coincidence."

Qi Lin spoke first.

"Ah."

David wiped the sweat from his face with a towel and said calmly, "I heard you went to work as an apprentice under Teacher Ye Sen? Did you just finish your job?"

"Ah."

Qi Lin nodded slightly.

"Goodbye."
