Closing his eyes and resting, Kasia recalled the route he had just taken, deepening the memory in his head one by one. At the same time, he also set aside a part of his spirit to think about his specific plans after leaving the Southern Forest, which would be to go to the Endless Sea Tundra.

Judging from the name alone, the distance between the two is very far, after all, one is in the south, and the vast area radiates three giant countries on the continent. Among them, the Flame Alliance occupies nearly two-fifths of the area of the southern forest, and the ecology and environment are different countries. The Endless Sea Tundra, on the other hand, is closer to the north, docking with the coast, and the frozen area of the sea is even wider, close to one-third of the empire's own territory. The resources are very abundant, and the islands beneath the ice were originally a fertile place when they were not eroded by the severe cold, as explained in ancient history books.

It was impossible for Cassihee to get there through any transportation, so Kasia decided to come to the Southern Forest from the beginning, with the intention of using Cassihei as a means of transportation. The unrefined route map is to go around the edge of the southern forest to the sea, and then choose the right time to skim over the shallow sea and enter the bounds of the endless sea tundra. Fortunately, the sea at the end of the southern forest is not very far from the tundra, and with Cassihe's ability to fly, it is completely enough to get there in three months.

Immersed in this thought, more than an hour had passed, when Kasia fell from the tree and returned to the location of the base camp in the same way as he had come.

Halfway through them, thirteen airboats slowly drove in a line toward the geothermal area. They were waiting for the sky to fully light up, and Cassie's choice of geothermal area was probably aware of something during this time. For example, a human who attacks itself seems to be able to catch its body temperature.

Following the end of the airship, Kasia soon followed the people observing the base into the geothermal area. After advancing for a few thousand meters in a certain direction, the airboat slowed down and began to strafe the lower part with a 50-heavy machine gun, and then, more than a dozen strings of landing ropes brought down more than 100 people, and in half an hour, a landing area for an airship with a body length of nearly 100 meters was cleared.

At this time, the airships began to descend one by one, putting down the weapons and ammunition in their cabins before returning to mid-air. By the time the thirteen airships had done this in order, the sun was barely falling through the mist.

There were more than 400 ground troops, but they were unusually small surrounded by ancient trees. In the southern forests, the mature leaves of ancient trees tend to be the size of a few palms of an adult. After sorting out the equipment, the commander stepped forward to give the final instructions for action, and when the time for them and the other two large teams was up, everyone felt out the potions they had prepared in advance and tied them all to their necks.

More than 400 people divided into five squads and fanned towards the left front. Dozens of people in each team walked behind the line carrying huge bags full of Regon explosives.

A random team was chosen, and Kasia quietly followed. Pulling away from a safe distance, the sound of gas gushing made Kasia appear more cautious. The speed of progress is not fast, and the people who observe the base only seem to know the approximate location of Cassiehe, where he is hiding, and they do not have accurate information.

Kasia made a note of his steps, and after about six kilometers or so, the line in front of him stopped. In addition to the dozen or so people around the guard, the remaining members quickly dug a large pit in the ground and buried a pile of Regon explosives in it. On the other side, other teams hundreds of meters apart were doing the same thing. Taking this opportunity, Kasia first took off her coat and then quietly approached a guard slightly farther away. It can be seen that most of the hundreds of people are in the first stage of surgery, and this time they will come here to carry out the mission, probably just because ordinary soldiers are not well adapted to this environment. After all, the current temperature has been constant at more than forty degrees, coupled with the humidity and the rotten smell of being evaporated, it is indeed not something that ordinary humans can withstand for a long time.

Approaching the guards gently, Kasia kept an eye on the observation range of the others nearby, and when no one was paying attention, she walked around to him, waved her arm slightly, and then dragged an unconscious body behind the tangled roots of the ancient tree.

In less than half a minute, Kasia walked out with a firecracker, stood on the alert, and began to sort out the clothes that were not too suitable. A mechanical watch that resists moisture, a flexible garment that stimulates the muscles of the body, a helmet made of good material, and a breathing mask that is not dull at all. The equipment is very specialized, and the weight of the firearm in the hand is much lighter than that of the ordinary standard firearm when it is equipped with blue and silver bullets.

Perhaps this is the full version of the firecracker, most of the materials used in the Imperial Army's standard firecrackers are made of meteorite copper and steel alloys in a certain proportion. Meteorite copper is not a scarce resource in the Empire, but it is also valuable compared to steel, which is about to be reduced to the same level as coal.

Turning his head to look at the group of people behind him who were handling the Regon bomb, Kasia focused his attention on the ancient trees around him. He remembered that when he was still there, Cassie Hei not only learned basic swordsmanship, but also seemed to have learned his part of the caution in action.

After more than ten minutes of standing guard, the team regrouped and moved slightly away from the original direction at a small angle. None of them seemed to know each other, and under the mask, no one noticed Kasia. I don't know if it's because of his improved acting ability, Kasia thought, and his teammates around him didn't speak, and they didn't even suspect him at all.

From time to time, his gaze wandered to the front of the team, which was the main member of the team, the four captains, all carrying pneumatic weapons. You have to be much more cautious than the people around you, and perhaps have seen more to know the dangers of hunting dragons in the southern forests.

While observing, Kasia silently followed the team. The sound did not give him a good reconnaissance effect at this time, and everything had to be searched by eye.

The team suddenly stopped at this moment, and the four captains in front of them made a vigilant gesture, and the team immediately dispersed. Kasia followed the man beside him and hid behind the nearest ancient tree, poking her head out to look ahead.

It was a low-lying ground with a concave foundation, and the accumulation of dead leaves was about to take the place of the earth, covering it with a thick layer. Many thick roots emerged from it, and the drooping plant aerial roots were more like a dark brown waterfall, blocking everyone.

There stood a huge old tree, its bark like a scar cut by time, like a few scratches left on the huge trunk of the wall, and it was still fresh. The bare rhizomes that spread around were as big as the main steam copper pipes in the factory. Coiled together, they hold the ancient tree firmly in the middle, like layers of staggered steps. There were undried blood stains on the dead leaves beside the ancient tree, and the corpse of a huge python mixed in between the roots.

Everyone looked up at the ancient tree almost at the same time, thick leaves stacked on top of each other, obscuring bundles of searching.

At this time, the four captains all took out their communicators and began to contact the surrounding teams through the reinforcement signals established by the communication machines on the airboat.

Only a minute or two later, the other three teams arrived, and at this moment, the sound of the airship propeller was getting closer and closer.

Kasia also looked over, the huge ancient tree with a trunk diameter of more than ten meters could indeed bear the weight of Cassiehei.

"But、、、," Cassiya moved slightly to the side of the ancient tree, "Cassiblack should know how to hide herself." Glancing back and forth around the ancient tree, Kasia stared at the thick layer of can, and then looked under his feet.
