Zou Hai’s voice was very gentle.

Gu Shen listened quietly... He had already read about the North Continent Fortress; Gu Castle Fortress was indeed a key guarding point, and the nickname "throat of humanity" was no exaggeration.

"And Quasi-General has been stationed at this fortress for ten years." As he said this, a smile uncontrollably appeared on Vice Officer Zou’s face.

"Ten years?"

Gu Shen looked somewhat surprised.

Having just met Lord Lin Lin... the appearance of this Gu Castle Guardian was quite young, looking only a few years older than himself.

"At the age of eighteen, Lord Lin Lin came to Gu Castle."

Zou Hai spoke softly, "A three-year term, and then another three years, and another three years... This year is the tenth. Of course, Lord Lin Lin was not the guardian of the fortress from the start; he worked his way up. Among the Investigation Corps’ top three important ’labyrinth missions,’ the first explorer was Lord Lin Lin. To this day, the planning authority for this mission remains in the hands of Quasi-General. Any exploring Investigation Corps must heed and respect the great one’s opinions."

Gu Shen pondered.

The labyrinth mission referred to the "Snow Mountain Canyon" north of Gu Castle Fortress.

This time, the elite team of the Investigation Corps Second Team was executing "Labyrinth Thirty-Eight," one of the series of tasks... The number thirty-eight meant that the previous thirty-seven routes had all failed.

And each exploration of a route could be planned into several phases, even dozens of phases.

"You must have understood... the general situation of this labyrinth mission," Zou Hai said earnestly. "The survivor... elite team leader Hong Zhong, is currently not stable mentally, and tomorrow we will conduct a ’Spiritual Assessment’ on him."

"Spiritual Assessment?"

Gu Shen frowned and asked, "Shouldn’t this have been done much earlier...?"

Vice Officer Zou sighed lightly.

"His mental state is too poor, he was unconscious for three days, so it was delayed until today."

Zou Hai spoke softly, "Actually, Lord Lin Lin is not as indifferent as he appears. Your arrival at Gu Castle is a good thing for both us and the Investigation Corps."

The piece of lost woodchip taken out by Hong Zhong, after being analyzed by "Deep Sea," was believed to possibly originate from Zhou Jiren’s walking stick.

This was the reason the North Continent Army invited Gu Shen.

"If possible, we hope you can participate in this ’Spiritual Assessment’ tomorrow to assist in our evaluation."

Zou Hai spoke earnestly, "Perhaps... we can discover a different clue."

Having said this, he stopped walking.

Before him was an old small attic.

Within Gu Castle Fortress, finding such an independent residence was not easy.

"Generally... this is a special guest residence for visitors from Central City."

Zou Hai opened the door for Gu Shen; a wave of rotting wood odor hit them, and he gave a bitter smile, "But these years, guests from Central City who have come here haven’t stayed overnight in a long time... This attic is the best residence I could find."

"It’s alright."

Gu Shen smiled; he was not particular about the quality of his accommodations.

He was not a man indulgent in luxuries; during the past year, even though Gu Shen had a spacious and comfortable yard in Changye, he had spent most of his time cultivating on Divine Temple Mountain and in Qingzhong.

Speaking just of the living environment, Divine Temple Mountain and Qingzhong were not much better than this place.

He would rest here tonight.

Using the Operating Breathing Method to counter the Golden Hoop, he would soon get through it.

Zou Hai paused for a moment as he closed the door.

"By the way..."

The vice officer spoke gravely, "Mr. Xiao Gu, there is something I must make clear to you."

Gu Shen raised an eyebrow.

Vice Officer Zou spoke with a complex expression, "Because this attic is not far from Lord Lin Lin’s attic. At night... you might hear some strange noises outside the door, but no matter what, please do not open the door."
