Oasis low hum

Outside the oasis, there was a rumbling sound.
This is an environmental change, but it seems to be a confrontation between vitality and decline, and it seems to involve a deeper change.
Oasis change is like a drop of water falling heavily on the lake, causing a violent shock around it, but when the change shocks the whole area, the lake remains very weak, similar to ripples
The whole falling star area is as usual.
The fog swells as usual, the evil spirits wander as usual, the merchants travel as usual, and the oasis people live as usual.
Only myth …
I just visited a resource mine to be developed, and the Lord of Steel suddenly frowned. "Have you noticed anything?"
Despite the blank face of the Ministry, the Lord of Steel still doesn’t feel that he is hallucinating. He will diffuse his mind and concentrate on exploring and finally discover the subtle changes in the world around him.
This change is so weak that it is like a breeze blowing or a tender seedling growing on the vast land.
Almost negligible and absolutely not negligible.
"This is …?"
Where did the steel Lord vaguely see a similar description? His brow screwed tighter and he frowned. After the memory, he looked shocked and finally found the information he wanted in the dusty corner deep in the memory warehouse.
"It’s a super oasis promotion!"
"When an oasis is promoted to level 7, it will have a huge impact on the whole large-scale change! So this is … "
Steel castellan stare big eyes.
But which oasis in this falling star domain can be promoted to level seven? Their steel city is the latest one, but it is still a lot of preparation.
Wait, could it be the Sword Flower City and Blackstone Alliance? Since the sword flower city can be hidden so deep, it is reasonable to hide a little bit more.
Thought for a while, the steel Lord shook his head again and denied his guess.
After all, myths can be hidden, but an oasis is roughly the size, and it can’t be hidden. At a glance, the Lord of Steel City can see that Jianhua City has not yet been promoted to a six-level oasis.
Wait, could it be the Chamber of Commerce for Burning Fires?
When the Chamber of Commerce for Burning Fires held an auction some time ago, it got a special epic ritual of’ popularity’, which can be used to gain popularity from its oasis and instill it into an oasis for rapid promotion.
It is not difficult for the fighting forces of the Chamber of Commerce to occupy an oasis quietly and operate and develop.
Thought for a while, the steel Lord shook his head again and denied his guess.
He thought it was still impossible.
The Chamber of Commerce for Burning Fires has both technology and strength, and it will certainly build a super oasis in the future. However, it is too short now. How can the Chamber of Commerce for Burning Fires quietly build a super oasis?
That popular etiquette was introduced by the seller at that time, and he seemed to be a little chicken.
Not to mention whether the fire-burning chamber of commerce can find an oasis with millions of people for them, and even if it can, they can build an oasis of level 3 and at most level 4.
It’s not a joke to build a level 7 oasis in a short time unless the fire-burning chamber of commerce can find an oasis with billions of people to recharge them!
Steel castellan denied this speculation again.
An oasis must leave traces, and if it wants to operate and grow, it must exchange trade with other oases around it. So where did this sudden promotion to super oasis come from?
After eliminating all the impossible options, there is no option left.
Steel castellan fell into a daze.
……
The two myths of falling star city are at a loss.
