The sun was beginning to set as it reaches six o''clock.

More and more zombies had turned around to attacked Xiaoyun''s army instead of going toward the building.

But Xiaoyun''s army consisting of five thousand people made light work off the zombies as they continue advancing forward.

After shooting almost to the brink of overheating their gun, the zombies were finally all cleared.

"Finally it''s over." Xiaoyun let out a sigh of relief.

"Yeah... But why were the zombies attacking this building in the first place?" Wuli mumbled.

"I don''t know." Xiaoyun replied back.

Suddenly, a person in a doctor uniform ran out of the building, then several security uniforms ran out of the building chasing after the person.

"Help me please! They are doing human experiment!" The person yelled out as they ran up all the way in front of Xiaoyun''s army.

"Sir, what should we do? There''s a women standing in front of us?" The captain in spoke through the walkies talkie.

"I''ll walk up there... let them in for now." Xiaoyun suddenly felt curious what they meant by human experiment.

As Xiaoyun walked all the way to the front with Wuli behind him, Xiaoyun''s soldiers were pointing their rifle at the security guard while the security guard pointed back with their pistol.

"Who the hell are you guys? Give our patient back." One of the security guard demanded.

"I told you, I can''t let them go until the commander say so." The captain replied.

"Where is he then?" Another security guard asked as they started to get a little impatient.

"Let''s not do anything stupid. I''m the commander." Xiaoyun finally arrived at the front as he signaled the soldiers to lower their guns.

"You''re the commander? Well you better give our patient back before we send in the 1st brigade after you guys." An security guard that seem to be the head walked up and signaled his securities to lower their guns as well.

"Speaking of the 1st brigade, where are they? Why can''t I see them?" Xiaoyun looked around the building, only to see not a single person out beside the security guards.

"We appreciate your help, but we need our patient back." The head security guard soften his tone, but avoided answering Xiaoyun''s question.

"What if I say no?" Xiaoyun started to get annoyed as he had came all the way here and didn''t even get to see the head of the 1st brigade.

"Why not just give the patient and we will go separate ways? You''re here to help us maintain the water plants right?" The head security guard asked.

"Let me talk to the commander of the 1st brigade." Xiaoyun signaled all the soldiers to raise their rifles as he started to have a suspicion to the security guard.

Something had clearly happened to the 1st brigade as the zombies amount weren''t even that much. Not to mention the 1st brigade having much more modern weapons than Xiaoyun''s army could easily wiped it.

"We can''t let you do that." The head of security adamantly refused.

"They did the experiment on the soldiers! That''s why they struggled to deal with the zombies! All of them were being experiment on without consent!" The person in the doctor uniform yelled out.

"That make sense, we did found an entrance but it was completely locked and it only had an electronic lock." Jixi mentioned.

"Okay, well we know where it is now. 10th company, go check on 19th and 20th. 11th company, go check on 17th and 18th company. Everyone else can rest inside." Xiaoyun gave out the orders.

After everyone got to their assigned place, Xiaoyun signaled Jixi to lead the way.

"This place is odd." Xiaoyun felt a little creepiness as they walked down an dark and silent hallway.

"Yeah... Anyway we''re here now." Jixi replied as everyone could see the metal doors with an pass code lock on the side.

"Do you know the password to this door?" Xiaoyun looked over to Tianci and asked.

Tianci shook her head in response, but pointed to the head of the security in the back.

Xiaoyun walked up to the head of security that was still being held by two soldiers.

"Do you know what''s the password to this door?" Xiaoyun asked kindly.

The head of security refuse to say anything, as all the security guards seem to don''t know how the door opens.

"You want to make it hard for yourself huh?" Xiaoyun pulled out a knife from his pocket.

"One last chance before I start slicing a thousand time, then pour salt all over it." Xiaoyun threaten.

"Pangxi, just say it! Why are we risking our lives for a bunch of scientist that won''t even care about us?" One of the security guard spoke up.

"They still have our families hostage. I-I can''t do that." Pangxi looked down as he still refuse to give an answer.

"Time is ticking... you know we can save your wife if you just tell us the password, or I''m just going to blowing this entire place up." Xiaoyun issued a final ultimatum.

"Fine, the pass code is 123035. I hope you can keep your promise." Pangxi gave in as he got scared after Xiaoyun mentioned blowing it up.

"Good choice." Xiaoyun walked up and entered the password.

The door started moving on it''s own and moved inward as it reveal the inside to everyone.

It looked almost like a bomb shelter as there was a long stairway down with reinforced concrete on all three sides.

"Miss Tianci, can you wear this soldier uniform and helmet so they don''t recognize you?" Xiaoyun handed Tianci the cloths.

Tianci took off her lab coat and put on the soldier uniform that could barely fit her, then put on a helmet.

"They most likely won''t have anyone defending down there, Jixi you stay up here and watch the water plant... I''ll go down with Wuli with two squads."

Jixi nodded in agreement as he directed two squads to follow the two.

"You guys better don''t do anything stupid... you guys don''t want to help people that experiment on other human right?" Xiaoyun signaled the soldiers to untie the securities.

After pausing for a second, the head of security gave up.

"We don''t want to do this either..." The head of security shared his opinion which all the securities guard nodded in agreement.
