After Dong Fang's explanation, Chu Nan finally understood the entire story.
It turned out that in the two years that Chu Nan had disappeared, the Noctem Chamber of Commerce had not been idle at all. Elkart had brought back the judgment and part of the data left behind by him before he disappeared to the Chamber of Commerce. The Noctem Chamber of Commerce's targeted research had obtained a huge breakthrough in their research on the teleportation door.
Through the simulation experiment of the battle between the enterprise-level battleship and the Star-Grade Martial Artist, they could even create a teleportation door out of thin air.
However, they had yet to completely understand the mechanism of producing these portals. The occasionally produced portals were also extremely unstable and could not be successfully used every time.
