Some even emerged directly from residents' sewers, causing immense fear.Many residents were scared and ran out of their homes.

But it wasn't just rats—bug pests also escaped through manholes.A sudden warning sounded across the sky, signaling everyone to gather at the place where insects were swarming to exterminate them.

Even Loose Cultivators were temporarily conscripted by Yumengyu.Lo Yangcheng, with Tian Luo Army and Dao Yuan students, led one group;while Yumengyu led the Loose Cultivators."Why are these bugs running out of their burrows?Their numbers aren't too many, but they're really annoying," someone asked.Yao Shitou frowned..."A negative emotion value from Yao Shitou +666!"Of course, he had guessed that this was likely Stinky Xiao's doing.

Such non-normal phenomena in the rat swarm were already under Tian Luo Army's surveillance.

But as Nie Tianlu said, they didn’t need to bother about it.Now thinking back, he realized the rat plague must be thoroughly cleaning the underground kingdom!Just after Li Shu finished his sword training and checked the negative emotion values on his backend, his screen went berserk!The continuous stream of negative emotion values in the hundreds and thousands kept appearing without pause.Although most of these bugs were exterminated, especially in areas where residents lived high up, the sheer number was terrifying enough!In just a morning, almost 3000 people provided Li Shu with an average of 300 negative emotion values each!Originally, Li Shu estimated that he still had to gather negative emotions for the fourth-layer Nebula Star.

Lighting the first star required 1 million negative emotion values;the second and third stars also needed 1 million and 2 million respectively.

By the seventh star, it would require a staggering 32 million.Where could so many negative emotions come from?In the end, these negative emotions came right to his doorstep…Within just one morning, Li Shu watched as his negative emotion values reached the 1.2 million mark before finally stopping.

He ate the exchanged Nebula Star fruit and lit up the first star!The moment the first star in the fourth-layer Nebula was illuminated, not only did Li Shu’s strength and stellar power increase again, but he also noticed that the originally thirty-six black crow lines on his map of stars merged with the surging stellar energy.

They then transformed into sixty-four lines.These sixty-four black crow lines swirled through the map like a sphere, dense yet never colliding, resembling meteors.After all, now the black crows were Li Shu’s most lethal cluster attack method.

The more black crows there were, the more targets he could hit simultaneously!But Li Shu was puzzled—where did these negative emotions come from?!He then received a call from Yao Shitou, who roared at him: "Can't you let Stinky Xiao give me a break?Why are you bringing so many escapees to the surface to be exterminated?"Li Shu was stunned.

He finally understood where the negative emotions were coming from.However, his first reaction was still to ask: "Are there any casualties?""No!But there are still some minor toxins spotted;it's not entirely safe!"
