But judging by Caitlin's performance in the office today, it's obviously impossible to make her believe this unless she sees it with her own eyes.

After thinking about it, Li Lin gave up the idea.

They stayed on the platform for a long time afterwards.

After collecting almost all the information, Caitlin walked up the rotten metal steps along the wall that led to the ground.

Unfortunately, this sewer platform seems to have been abandoned long ago. The stairs are cut off halfway and cannot reach the surface at all.

"This should be where the scavengers live, right? No wonder the facilities on this platform are abandoned and unmaintained."

Li Lin sighed.

More than half a year has passed since the five-year agreement with the parliamentarians.

Although the Lower City is much more stable than before under Hillco's control, the hostility of the Zaun people towards the people of the Upper City has not diminished in the slightest.

Even though he had asked Hilco and Vandel to do their best to promote themselves and the Gilaman family, the effect was minimal.

As long as Zaun’s most basic environmental problems are not resolved, the conflict between the two city-states will never be alleviated.

Li Lin knew very well that the main source of the haze was the Philos family's Hextech crystal production factory.

Even though he had improved it to produce energy crystals with less pollution, ordinary crystals only reduced production.

After all, the upgrade of a product cannot be achieved overnight.

Even the Philos family, as a major shareholder, has invested in the power plant and is planning to make the improved energy crystals go the high-end route.

However, there are still many places in the market that need Hextech crystals. Before electricity becomes popular, it cannot be banned for the time being...

"I really don't want to go against the Philos family now. Why don't I research an air filtration device first as a transition..." Li Lin muttered to himself.

Caitlin's gentle voice from a distance brought his attention back to reality. "Li Lin, what are you still doing? We should go to the next place."

Li Lin looked up and saw that Caitlin had already walked to another fork in the passage and was waving at him.

"Come quickly, I can basically determine the direction the murderer escaped."
