Beside Utara was Captain Hua who didn't look any better from the fortress's warden chief Li. Gu Xie death was very unexpected, at least who will kill someone who has been sentenced to death? The 4 prison guards have been detained and now went through investigation.

"How the intruders escaped?" Xiao Tianyao chill voice echo in the silence room.

There were 2 intruders last night. One has been confirmed by Xiao Tianyao as Senja, even though he didn't announce it. So for meantime it was only him who knew about this truth.

"Answer to commander Xiao, unfortunately the intruders managed to escape" Captain Hua halted for a while as he swallow his saliva when he delivered his report. "… One of the intruder managed to escaped after wounded one of our soldier while the other intruder who came into young miss Senja room can't be found" Captain Hua kept his head down until he finish, too afraid to even look the man in front of him who 3 years younger than him.

"Bring here the wounded soldier now" When Xiao Tianyao gave his order, one of the shadow guards made a silence bow before he carried out the order.

"What was the cause of Gu Xie death?" Xiao Tianyao circled the table to walk directly towards Doctor Hong who stands unnoticed at the corner. His blue bright robe fluttered by the wind from the open window, just like Captain Hua, he also didn't dare to look directly into Xiao Tianyao eyes so he look Xiao Tianyao hands instead.

"Answer to Commander Xiao, the cause of death of Gu Xie was emphysema, difficult to breath because lack of oxygen, which ultimately causes death. It seems his condition isn't good to began with and then the harsh interrogation made it worse" Doctor Hong explanation regarded with sharp stared from Xiao Tianyao.

Xiao Tianyao looked at the young Doctor in front of him who still have his head down. The young Doctor's black hair tied neatly on top of his head that make his appearance looked fresh and also emphasized his hard face line however, somehow his face looked pale.

"In other words, natural death?" Xiao Tianyao confirmed Doctor Hong diagnosed.

"Yes" He replied firmly.

Not long after, a shadow guard who left to fetch the wounded soldier came back. With him was a soldier with bandage on his left arm. When they were close enough to Xiao Tianyao, both of them kneeled to pay their respects.

Xiao Tianyao didn't let them rise so they also didn't dare to stand up and kept their kneeling position while answer the questions.

Instead of Xiao Tianyao, it was Utara who was giving the question towards the wounded soldier.

"From which unit you are?" Utara asked.

The wounded soldier rise his head to look at Utara "Answer to Lieutenant Utara, this subordinate is Feng Chang from archery unit" The wounded soldier answer carefully.

"Archery unit?" Utara was looking at Feng Chang questioningly. Normally archery unit will be stationed at outside of the first fort. "What the Archery Unit was doing at the inner fortress?"

"This subordinate happened to be at the border of the first gate and saw a suspicious figure, therefore this subordinate followed him" Feng Chang replied and his statement gained justification from Captain Hua.

"The intruder indeed ran towards the border of the first gate and disappeared" Captain Hua added a detailed explanation.

Utara didn't say anything for some second as he was deep in thought. Head Quarter of East army fortress has 3 main fort surrounded it, outside the first fort was Archery Unit stationed, the second fort was Armed Unit stationed and the third fort was Chivalry Unit stationed. With three layers of protection and a few amounts of shadow guards scattered all over the places, it was impossible to penetrate their defense except the intruders weren't someone from outside, instead they were someone from inside the fortress. In that case the problem will reach further complication.
