The mode of contact in dreams required a special ability to accomplish.
Clearly, Lu Zixun didn't possess this ability.
This mode of contact was essentially a one-way channel.
That is to say, even if Lu Zixun slept for a year, as long as An Xiao didn't contact him, that year would be wasted.
And Lu Zixun was brought to tears by his own stupidity because of this.
He actually hadn't realized that this was a one-way form of contact.
Could it be because he'd slept too much that his brain had become muddled?
After making fun of Lu Zixun's actions, Zeng Haoyang finally offered a solution.
Since An Xiao could contact Lu Zixun through entering his dreams, it meant that An Xiao was definitely still in the Crimson Land.
If he was in the Crimson Land, then wouldn't it be easy to find him?
After all, although derivative abilities carry extraordinary powers, this doesn't mean that the users themselves are extraordinary and their abilities can't manage cross-world contact.
