The next day...

Everything went as planned for Xiaoyun. First, the restocking of the office building was successful, as the logistic soldiers were able to avoid the zombie hordes and deliver the supply inside.

As a precaution, Xiaoyun ordered the soldiers to restock more RPGs in case of more tank mutants.

Then, the 4th and the 5th regiments repeated the same thing, just like how the 2nd and 3rd regiments did, turning on the loudspeaker as they fired outside the office building before retreating inside.

However, it was where the trouble began.

"Xiaoyun! There are so many mutants in the streets!" Wuli yelled out as she pointed to the right of the office building.

Xiaoyun immediately took out his binoculars and took a look himself.

Ten tank mutants were running toward the office building, almost like a pack of wolves hunting together.

Still, there was still some distance before the mutants got there, as there were so many zombies blocking their way, and they didn''t move aside at all.

"Xiaoyun, should we send in reinforcement?" Wuli asked.

"No, reinforcement is not enough. You go to the artillery, and I''ll order the other five regiments to get them out...

This can''t be the only mutant group going towards there." Xiaoyun replied as he remembered how mutants usually go together with another type of mutants.

Wuli hesitated for a second as she remembered how the soldiers had said it was too close, but seeing Xiaoyun''s urgent face, she agreed to it.

As Wuli rushed downstairs, Xiaoyun pulled out his walkie-talkie.

"1st regiment, I need to immediately evacuate the 4th and 5th regiments out of the building, and all other units go towards the office block and assist transportation."

After hearing an affirmative from them, Xiaoyun switched to the two regiments in the building.

"Ten tank mutants are all heading towards the office block. Try to break out if you can... Or retreat to the upper floor. Over."

"Yes, sir." Both Major replied.

Xiaoyun took out his binoculars to check the mutant again.

They were still about an entire block away as the zombies got more and more dense, forcing the mutants to slow down.

"Do they not care about each other at all?" Xiaoyun mumbled as he watched zombies get crushed by the mutant with little regard.

As the mutants approach closer and closer to the building, Xiaoyun suddenly hears a loud sound below him.

Xiaoyun watched a shell fly up into the air, and as it went down, it didn''t hit anywhere near the mutant, nor did it explode at all.

"What the hell is going on?" Xiaoyun asked through the walkie-talkie to Wuli.

"It''s a test round. They are doing the measuring right now to fix the angles." Wuli responded patiently.

As Xiaoyun waited, the mutants were now half a block away from Xiaoyun''s mind. was getting more and more nervous for the soldiers inside the office building

"Lingang, how long until your troops get there?" Xiaoyun asked urgently.

"In twenty minutes, but I can speed it up to ten minutes if we put it on max," Lingang replied.

"Put it on max! Get there as fast as you----"

Another round of artillery shells was shot and landed over at the other side.

The six in the middle were bleeding severely, and their entire upper body looked more like a barebone frame.

Meanwhile, the two that were more relatively back and less focused were almost still perfectly fine.

"Everyone fire at the injured one!"

The soldiers immediately snapped back to the moment as they pulled their triggers and began firing at the target.

Instantly, the six mutants fell onto the floor as the bullet somehow was easily able to penetrate their non-existent skin and muscle and into their head.

But this enrages the other two mutants as they start rushing towards the soldiers at full speed.

On top of it, all the zombies from outside the building began flooding inside the building again.

As the remaining soldiers began retreating back towards the stairs, Zhen Ren was still sitting in the mounted gun at the end.

"Sir, we need to retreat now!" One of the captains tried to pull Zhen Ren back, but he adamantly sat still.

"I am not leaving until all of them are dead." Zhen Ren yelled back.

The captain thought for a millisecond and instantly made up his mind.

"Sorry, sir."

The captain knocked out Zhen Ren and instantly dropped his guns as he carried Zhen Ren upstairs.

As the zombies began trying to rush up the stairs, the 5th regiment upstairs had already set up a defense and immediately opened fire as soon as the last two got upstairs.

"Where is Zhen Ren?" Li Miao asked as he walked up to the captain.

"He''s here... I had to use force since he didn''t want to retreat for some reason." The captain nervously replied.

"I probably should have told this to Commander Xiaoyun before he assigned him for this... Carry him to the third floor."

After the two went upstairs, Li Miao focused back on the important matter at hand.

"Please tell me they can''t use the stairs."

Li Miao watched the zombies fail to go up the stairs, but they were still slowly getting closer and closer up by using each other''s bodies as a smoother stairway.

Still, they were nowhere near the biggest threat, as most of them were instantly shot down by the soldiers.

Li Miao was fully focused on the two mutants who finally approached the stairs full of zombie corpses.

The mutants push the corpse to the edge and instantly break the stairwell window, and the zombie bodies go flying down to the 1st floor.

And to everyone''s surprise, the mutant began slowly moving up the stairs by using its two massive arms like a pair of crutch.

With every step the mutant took, the soldiers could see the stairs crackling for help as if they were about to break at any moment.

Suddenly, Li Miao had an idea.

"Everyone, give me your grenades!"

Two soldiers walked up and handed their grenades to Li Miao as all the soldiers began retreating.

Li Miao pulled the pin and threw the grenade right at the top of the staircase before it went off.

With a loud explosion, the entire building shook harder than ever as all the soldiers held onto whatever they could to stay still.
