Chapter 138 Heavenly Sword

Qiushan Mountain.

Guarded day and night by three thousand elite, it was one of the most important defense points within the territory of Lingxiao City.

Unlike the military workshops established within Lingxiao City, wrapped by layers upon layers of city walls, the defense point of Qiushan Mountain, although surrounded by loops of barbed wire, ultimately could not compare to the defensive power of city walls. Within a year or two, many spies from various forces infiltrated Qiushan Mountain, trying to uncover exactly what was inside.

However, the matter of the Demon Realm Rift was top secret. Apart from Gu Chaoyang, Gu Chifeng, and a handful of other core members of the Gu family, even Gu Changfeng, the head of the Gu family, was unaware.

And the Demon Realm Rift would only open at fixed times; occasionally, a few spies paid a great price to delve deep into Qiushan Cave and still could not grasp the true secrets within, at most considering it a military armament storage point.
