"Last Pure Land Domain" 

Knowing that Axelle is now trying to create a domain to help them out, the Godfather could only keep an eye on their surroundings. 

Even if Axelle had the invincible buff when he was creating a domain, if someone discovered that Axelle was creating a domain, they might be guarded against him and right after he finished creating the domain, he would be besieged to death, not to mention helping Ainsley. 

While the Godfather was looking out for possible enemies, Axelle had started to weave the flat domain, just like painting something with his imagination. 

Because domains needed the creator to have a high level of imagination, usually, people created a domain with the scenery that they had seen before or something that was deeply imprinted in their mind.
