I blanch!

This action directly upgraded me to level six!

Health points soared from over 1200 to 1823, mana increased from over 300 to 668, and even skill points increased to 20!

Beneath the steel mask, Li Lin's face showed an irrepressible joy.

But what made him even more excited was that the system panel actually unlocked a new function: career advancement.

He thought for a moment and quickly checked this function, and found that his current profession of [Mechanic] would be renamed [Mechanical Heart] after being promoted.

However, this "professional advancement" has a prerequisite, which is to improve the affinity with the mechanical creations that you have made.

What troubled Li Lin was that there were no other hints except the so-called "increasing affinity with mechanical creations".

The [Mechanical Affinity] skill can increase affinity for machines, maybe it’s related to this?

This skill is currently at level 3, and at my current level I can upgrade it to level 6...

But when he heard the sound of rushing water behind him, Li Lin shook his head and temporarily put aside the idea of ​​upgrading his skills.

Now is not the time...

"Li Lin!" Caitlin's anxious voice echoed in the narrow passage.

"I'm here."

After more than ten seconds, Caitlin and Grayson, carrying sniper rifles, ran to the passage where he was.

As soon as she saw Li Lin, Caitlin hurried over and asked, "Are you okay?"

"With the power armor, what can happen to me?" He chuckled. "But you guys, are you okay?"

"Neither Sheriff Grayson nor I have..."

As she was speaking, Caitlin frowned slightly, her eyes missed Li Lin and looked behind him.

At the next passage entrance, Zack, who had transformed into human form again, stood with his back to them in a daze in front of Tucci's body, as if thinking about something.

Caitlin's blue eyes flickered with worry, "Zach...is he okay?"

She knew exactly what Zach had done just now.

Just by looking at the tentacles hanging above his head, Caitlin, who had a keen eye for detail, could tell that he was in a very low mood at the moment.

"Zach is easily affected by negative emotions, so he just went crazy." Li Lin looked back and sighed, "Now that Tuqi is dead, he should be back to normal."

He'd explained this before when he told Caitlin the story about Zach, so today he was explaining it more for Grayson.

"Let's go and take a look."

Grayson's tone contained a hint of sigh and sympathy, which made Li Lin and Caitlin feel a little relieved.

The three of them remained silent and stopped about three or four meters away from Zack.

Before they could speak, Zach said in a frustrated tone: "I'm sorry... Did I cause you any trouble?"

Li Lin turned his head and looked at Caitlin, and read what she wanted to express in her watery eyes.

Coincidentally, he thought so too.

"What are you thinking? Without you, we can't even find the shadow of Tuqi. How can you let us cause trouble?"

"But if I hadn't caused trouble just now, you could have solved it earlier..."

Li Lin walked over to Zach, patted his arm gently and said comfortingly:

“You can see that this rat can smell us from more than ten meters away.

"He also has alchemical venom, which uses some special alchemical chemical material to make him invisible...

"Without you, things wouldn't have gone so smoothly today."

Hearing him say this, the tentacles on Zack's head stood up and shook twice, "Really...really?"

"Of course, Sheriff Grayson, those elite law enforcement officers and I couldn't help much." Caitlin comforted him with a smile.

Zack could sense the kindness and sincerity in the three people's hearts, and his mood couldn't help but improve. "Thank you..."

"No, we should be the ones thanking you," Grayson said with a laugh. "Once this matter is resolved, I will personally visit your parents and present you with a banner and a bonus for 'heroic acts of bravery.'"

"Then...will my parents be happy?" Zack asked cautiously.

After receiving the affirmative answer from the three people, he immediately jumped up excitedly, scaring Caitlin and Grayson so much that they hurriedly dodged the splashing sewage.

"I'm going to tell Mom and Dad about this right now!"

After saying that, without waiting for their response, Zack immediately turned into a pool of gel-like liquid and flowed away with the water, disappearing from the sight of the three people.

Grayson looked at the direction where Zack disappeared and couldn't help but shake his head and sighed: "What a child's temper..."

"Of course, Zach is only half a year old since he was born."

As soon as Li Lin finished speaking, Caitlin interrupted with a hint of impatience, "So, can we talk on the surface? Don't you find this sewer environment disgusting?"

Li Lin and Grayson looked at each other and laughed at the same time.

"I've just contacted Marcos via intercom. Let them transport the body of this mutant rat to Pitto."

…

…

It has been two days since the case of "serial killer" Tucci was solved.

The corpse of this giant rat, which was mutated by chance due to alchemical venom, was transported back to Piltover Academy by law enforcement officers and handed over to the biology professor there for research.

Li Lin was not interested in Tucci's corpse and was not good at biology, so he did not ask Heimerdinger to dissect it.

In the past two days, in addition to helping Kassadin make the "Hextech Power Armor", his attention has been on the so-called "improving mechanical affinity" in "professional advancement".
