Xiao Jin wanted to borrow the Han Clan's Space Wormhole, so he had no choice but to deal with the trouble from the Hong Clan.
The threat from the Hong Clan, or rather the Wind Lightning Pavilion, was not baseless.
The time spent inside a Space Wormhole was, at the very least, calculated in days.
Although the Hong Clan would not have people watching the Han Clan at every moment, there was absolutely no hiding the activation of the Han Clan's Space Wormhole from the Hong Clan's eyes and ears.
When the time came, with Xiao Jin inside the Space Wormhole, if the Hong Clan outside wanted to tamper with something, could he still expect the Han Clan to risk their lives against the Hong Clan for someone they had never met before?
To put it more bluntly, once Xiao Jin and the others entered the Space Wormhole, they would be fish on the chopping block, left at the mercy of others.
When the time came, all it would take was one Dou Zong using Spatial Power to blur the Spatial Mark on the other side a little, and Xiao Jin inside the spatial passage would be driven into utter chaos.
This was not him talking nonsense. In fact, in the original story, when Xiao Yi Xian repaired and maintained the Space Wormhole for the Luo Clan in Tianya City, she had used a similar method.
At that time, Luo Cheng, the head of the Luo Clan, had said to have several Dou Zong join forces to reinforce the Spatial Mark on the other side of the passage.
In other words, even from this side of the Space Wormhole, several Dou Zong working together could still affect the Spatial Mark on the other side.
As for the principle behind it...
