"That technical problem isn't that easy to overcome, is it?" said Dream, "Hmm...... But there's a ton of people on the surface working on the magic engine. Pen Fun Pavilion www.biquge.info"

"Although the development of a magic engine is forbidden on the surface, there must be someone operating it in private...... "Nightwind said, "but I don't think it's that easy to accomplish." ”

A high-powered magic engine is not a simple magic machine. Being able to bring an airship to such a height is quite terrifying, and it can also produce considerable effects when used in military affairs.

"Someone must have revealed the core technology to the surface people. Han Jiang said, "As far as I know, that engine is one of the important topics of the magic academy, and it is not an easy task for a great magician. ”

It is well known that the surface people are not overly skilled in magic. Like Night Breeze and Gleni, they are very rare among the surface people. It was almost impossible to expect them to be able to overcome the problems of the great mages.

"Who, so bad?" Phil was a little emotional, "Actually let such a large group of crazy people enter the floating continent!

The people of the Floating Continent would definitely not do such a thing, but the people on the surface could not get information......

"Don't think about it yet. Han Jiang said, "Now if you want to find out who leaked the secret, there is no clue at all." ”

I can only know that this is a very powerful person.

"Dream, you should tell those security personnel about this information as well. Nightwind said, "It doesn't have anything to do with those bases underground, but it's ......."

Before Nightwind could finish speaking, he was interrupted by a violent shaking of the earth's surface.

The house began to shake, and you could feel a majestic force underground, and the tremors were strong and weak, as if there was a strong beast striking the surface again and again.

The four of them unfurled the magic wall, but it was clear that they were worried in vain - Sunset City's buildings were sturdy and would not be damaged by this level of shaking.

"This ...... What's going on?" Phil was a little confused.

“…… Earthquakes? No, it doesn't seem to be. Han Jiang said.

Earthquakes do not occur on the floating continent, but the surface does, and Hanjiang also learned about the phenomenon of "earthquakes" from the knowledge in books.

"It's certainly not an earthquake, it's not like that. As a surface person, Night Wind knows the situation of earthquakes better: "Earthquakes don't shake like this many times in a row." ”

Although there was no damage to the house now, the four of them still felt a little dangerous - they had found a more open place, where it was safer.

They weren't the only ones here, there were others who had taken refuge here - of course, there were no surface people. After the previous attack, the security guards checked the entire city again, and this time it was really no problem.

"Tell the whole city, tell the whole city. The sound from the horn attracted the attention of the four.

This type of horn is common in the city and is usually used to release some important information...... It seems that there is a reason for the shaking just now.

"The shaking just now came from an attack by the surface people underground. The attack has been successfully intercepted by the magic array, so please don't panic too much. Repeat,......"

…… Surface people attacked underground?
