Chapter 408: Chapter 399: The Cunning Merchant Xuan Ziwen?

Xuan Ziwen, sitting inside the All-Terrain Self-propelled Artillery, finally had a less icy expression on his face. The value of a hundred-thousand-year soul ring was immeasurable. Moreover, since the hundred-thousand-year soul beast had been destroyed by his specially researched Aggregated Energy Piercing Ion Ray, equivalent to natural death, anyone could absorb its soul ring. So, this was indeed a priceless treasure.

This time, to counter the Beast Tide Army, the Tang Sect had put forth so much effort, and with this item, they finally had some return on their investment. He hoped that the disciples could also gain some rewards.

It took only a few minutes for all the All-Terrain Self-propelled Artillery units to "walk" back on their own. Those long legs climbing the city walls as if over flat ground made Shi Xing's eyes widen in amazement.

This was just too powerful, the attack strength was terrifying, and its adaptability to terrain was truly formidable!
