Steel steam and flame

The underground sewers are performing their job perfectly, channeling large amounts of rainwater away from the city, so that only a small part of the low-lying areas are flooded by rainwater.

Cassia has not forgotten this habit of her own. Whenever she goes to a new city, the first thing to do is to understand the current city's underground sewer system through various means-drawings, maps, etc. This is something that has been engraved on his spirit, and he has no intention of changing it.

It is much more convenient to do this now. Mental perception replaces sound wave pulses. While walking forward, the three-dimensional map of the underground waterway has been drawn in the head and gradually becomes clearer.

There is still considerable order within the city, and the external situation has not had much impact on them. Perhaps similar situations occur frequently, and people living here have a stronger psychological acceptance limit.

Without wasting time, Cassia chose a route with almost no pedestrians, relying on her legs to travel between buildings and alleys. It was about half an hour after arriving at the city's main airport. The contact person's fourth-stage surgical aura was captured by Cassia's extremely keen perception, which saved a lot of tedious procedures.

"Mr. Cassia!" When he noticed someone standing outside the door, the contact person couldn't contain his surprised tone. Because the way he discovered Cassia was through Cassia's active knocking on the door, rather than through his own spiritual perception of the surroundings. As an experienced four-stage surgeon, he understood that at such a distance, all his methods were meaningless. The opponent's attack can kill him immediately. But he didn't have the distance or time to escape.

"Let's go immediately, I shouldn't be late." Cassia then opened the door, entered the connector's rest room, and greeted politely. The other party is a member of the Chira Andi family and has been stationed in this city for a long time. "It would be a good choice to go there earlier. The current changes happening across the continent do not allow us to act at our own pace."

While speaking, Cassia's eyes naturally fell on the corner of the room, where a rectangular silver-white metal box was placed, exuding a heavy aura.

Seeing this, the connector immediately said: "I don't know where the goods were transported here. I said they were going to be handed over to you, Mr. Cassia."

Cassia walked straight over and lifted up the metal box. The weight of more than a ton already showed what was inside it: "Finally returned it to me." After saying that, he curled his lips and said, "If you don't borrow it next time, you can do it yourself." He doesn’t look like a lender at all, but more like someone who borrows something.”

The simple complaint against Grote ended here. Cassia also turned to look at the door first and motioned to the contact person. So during the brief conversation between the two, a large airship that had been prepared for a long time left the airport with the sound of its whistle, and sailed towards the distance that was invisible under the heavy rain.

The distance between the outer urban circles outside the southern forest is not extremely far. From the outermost reaches to the urban area near the southern forest, large airships can arrive in less than two days.

Cassia is not in a hurry about this. The time spent on transportation can be exercise or rest. What changes is just the environment and has no impact on him. Spirits are all on the line of evolution, and another emerging idea.

Moreover, when we return to the southern forest again, we will see Cassie Hei, whom we haven’t seen for a long time. I don’t know what it looks like now, but the network of underground caves must have expanded to a large area. With subsequent construction work by professionals, it has probably become an underground fortress.

Imagining what Cassia looked like, Cassia did not forget to open the metal box. The twelve solid red mercury sticks neatly embedded on the shock-proof cushions were gifts. Because he digested and absorbed a lot in the Avalon Agency, Cassia can endure hunger now facing these solid red mercury.

But I still apologized to Sukarius in my heart. After all, when I went to pick him up from the first breeding pen, he "ate" all the promised gifts, leaving only a metal box.

The time on the airship passed quickly, and it was early in the morning when we arrived at the city on the edge of the southern forest. Lightning under the rain clouds illuminated the entire land from time to time, allowing Cassia to see clearly what was happening below.

The city where the airport is located has somewhat lost the prosperous lights of the past peacetimes, and looks dim under the brilliant light of lightning. The large-scale transfer of people has put the city in this circle into a state of war. Although it has not yet reached the period when lights are controlled, the appearance at the moment is not much different.

Those who stay here are either surgeons or professional soldiers. The empire and military headquarters have a large number of troops here, and a few lights illuminate various war equipment. The airport was extremely busy, and airships taking off and landing filled a small area of ​​the sky. In the expanded airport, military battleship-class and cruiser-class airships are beasts with hidden auras, quietly accepting the erosion of the heavy rain, just waiting for the moment when their own steam furnaces burn again.

Not far from the airport, Cassia looked at the armors running back and forth one after another with nostalgic eyes to help carry super-heavy cargo. One of the reasons why Xiaocheng himself would apply for the Imperial Heavy Industry School was for something like this.

"At the defensive city wall, the number of battle armors and bionic machines will be even greater, dozens of times that here. Due to time, some military airships have also joined the construction process to help transport necessary building materials. "As a special guest and a special member of the alliance, Cassia's itinerary is kept confidential, and there are dedicated contacts in every place to make necessary introductions and arrangements.

"But after the underground cave appears, the construction of the defensive wall will be further postponed. Although no actual information has been released, judging from the recent mobilization of personnel, machines, etc., the situation ahead has indeed been significantly affected. "

When he said this, the connector lowered his voice, almost lip-talking: "Archaeologists and geologists have already passed by. According to my own experience of being stationed all year round, something bad may have happened underground. Otherwise, Under the current circumstances, these scholars and researchers will definitely not let them go to such a dangerous place."

Suddenly, Cassia remembered another special feature of the southern forest. Beneath the southern forest is the largest entrance to the underground world in the entire Three-Phase Continent.
