The premise is that there is no powerful blood magic master like "Bloody Lady" Faris Noradi.

Moreover, Jarvan IV, carrying the wounded, had just set out from the Tranquil Lake Plains and returned to Demacia. It would take at least several weeks to reach Lunwall on the other side of the mountains.

In the workshop, Li Lin transformed the armor into ordinary clothes, and then urged Zuo Yin to go find Kassadin or Baobao and the others to play.

Of course, according to Zuo Yin's personality, he still wanted to stay with Li Lin, especially after they disappeared for a few days.

However, in order to make Li Lin accept her better, her temper has changed a lot in recent days.

Knowing that he really had something to do, Zuo Yin didn't bother him any more. A portal appeared under his feet, and his petite body fell into it, disappearing instantly.

There was no one around, so Li Lin breathed a sigh of relief.

The technology required for the battlefield mecha Urgot is not very high, and the most advanced technology is only electromagnetic weapons and compressed ammunition.

It's just that the size is there, and it can't be transformed like the Tyrant Warrior, so he had no plans to make it before.

In addition, this type of mass-produced combat mecha is a consumable and the cost needs to be considered, so Li Lin is not prepared to use more advanced technology for "Urgot".

Dozens of mechanical engineers prepared the materials and transported them to a secret manufacturing plant in Zaun that originally belonged to Renata but was now fully controlled by him. The plant was used to manufacture some war equipment that was inconvenient to manufacture at home.

But before he could transform into his armor again and determine the coordinates for teleportation, a private call from the academy interrupted his plan.

[Master, Professor Heimerdinger is calling from his personal number.]

"Put it in for me."

As Li Lin finished speaking, the AI ​​picked up the signal, and Heimerdinger's distinctive, shrill voice reached his ears: "Oh, oh, oh~~ Good afternoon, kid, are you free now?"

"Of course, Professor, what can I do for you?"

"Actually...it's not a big problem."

Heimerdinger's tone was a little conflicted, and Li Lin suddenly had a bad feeling.

"Just tell me, Professor. Did those kids cause trouble in the academy?"

"Making trouble? No, no... well, I mean, it's definitely related to Boom-Boom, but it's not a disturbance." Heimerdinger sighed. "It's hard to explain over the phone. Anyway... come over first! I'm in the office."

After hanging up the phone, Li Lin immediately changed into his armor form, first determined the coordinates outside the office building and teleported there.

Due to the limitations of Hextech Teleportation, there was a low probability of errors when teleporting to a room with no leaks, so he did not go directly to the office.

After arriving at the academy, he flew into the sky outside the office building, entered the top floor through the open window in the corridor, transformed his armor into ordinary clothes, and then walked towards Heimerdinger's office at the end of the corridor.

Li Lin had just approached the double door of the office when he heard Baobao and Milo arguing with each other. Ike was trying to calm them down.

But besides them, there was another girl whose voice was equally clear, youthful and full of energy.

Li Lin knocked on the door twice casually, and after getting Heimerdinger's consent, he walked into his office.

The system panel reminder that followed made him stunned for a moment:

[Congratulations! You have contacted 30 heroes, increased your level by 2, and gained 2 skill points.]
