The Nu Lin Jing Tao did not dare to immediately contact human society. They first landed on some nearby islands to establish forward outposts.
Coincidentally, not long after they arrived on Earth, the ruins of this overseas immortal appeared in the vicinity.
After urgent communication with Jiu Yuan, the Nu Lin siblings decided to explore the ruins of this overseas immortal first, as there might be good things left behind by immortal powerful beings.
Although the teleportation array had been restored, it had only been partially restored. Teleporting these thousands of people had already consumed all the energy accumulated by the teleportation array.
They were in urgent need of finding new energy to replenish the teleportation array so that they could teleport more people from Jiu Yuan. These ruins of the overseas immortal might contain the energy they needed.
Just then, psychics from all over the world entered this sea area to explore the ruins of the overseas immortal, and all of them became prisoners of the merfolk.
Some of the psychics were brutally killed by the merfolk, while the remaining ones, terrified, could only surrender to the merfolk.
The merfolk were not afraid of these psychics rebelling. They placed special collars on the necks of these psychics. The craftsmanship of these collars was very complex. Once worn, the wearer's internal energy and psychic abilities were suppressed, and they could not exert any power, only their physical strength.
However, in terms of physical strength, ordinary humans were far inferior to these merfolk.
Even the strength-type psychics, after wearing these collars, had their physical strength reduced to only slightly higher than that of ordinary people.
Next, they were forced to work, moving stones and building the massive structure.
Furthermore, each of these psychics was summoned for individual interrogation. The Nu Lin siblings gained a basic understanding of this world from the mouths of these psychics.
They also learned that with the decline of heaven and earth spiritual energy, the cultivators on Earth, those truly powerful beings, had either died or fled, leaving very few behind.
Now, with the spiritual energy revival and the awakening of psychics, their strength was far inferior to that of these merfolk.
Upon learning all this, a seed of ambition grew in the hearts of the Nu Lin siblings. They wanted to dominate the oceans of the entire Earth, and even the entire world. As the saying goes, when the tiger is away, the monkey becomes king!
However, they still maintained a sliver of rationality because they also understood that this world was different from a thousand years ago. In this world, there was something called technology!
In the face of technology, especially human military technology, even merfolk had to avoid its edge.
They also knew about tanks, airplanes, missiles, and even nuclear bombs, and the merfolk were very wary of these things.
After all, a nuclear bomb detonated underwater could destroy the entire Jiu Yuan. Therefore, they planned to proceed slowly.
Just then, the Xuanyuan family's Luan Feng Hao broke in, and a great battle ensued.
This time, the Nu Tao siblings found themselves facing a tough opponent. They lost over a hundred merfolk, a loss greater than all the losses they had suffered since returning to Earth.
"Sister, don't worry. Even if you don't make a move, those people are at the end of their rope. They'll be exhausted to death. Those fish-heads can take care of them!
As far as I know, there aren't many people in human society with the strength of those people just now!"
Nu Lin Jing Tao was completely unconcerned about the recent battle. Within the merfolk society, there was a hierarchy. Those like them, with appearances close to humans, belonged to the noble class. As for those with fish heads, they were the lowest class, essentially cannon fodder. These noble classes didn't even consider them as their own kind, merely using them as cannon fodder and tools.
Of course, among the merfolk, there was another type whose appearance was almost identical to humans. These merfolk were the royal family of the merfolk. They held esteemed positions and almost all of them had centuries of cultivation and innate powerful magic.
Even among the very numerous merfolk population, those capable of evolving into the royal family were few and far between.
Although Nu Lin Jing Tao was comforting his sister, Luo Yun still felt uneasy.
"Brother, did you see that thing that flew away at the end? According to those captives, that was a missile!
I can feel that the destructive power of that thing is astonishing. Even if I used all my magic to release the Sky Covering Water Curtain spell once, I could only barely resist one of its attacks!"
"Sister, don't worry. That thing called a missile has many limitations in its use. It must lock onto a target before it can attack precisely.
However, it is very difficult for that thing to lock onto a moving person. We have countless ways to evade its attacks, especially if we hide in the water, that thing becomes useless!
Moreover, as you saw, that thing couldn't function normally within the barrier of these immortal ruins. Relying on that thing to kill us is purely a joke."
Nu Lin Luo Yun nodded, hoping so.
It was just that neither of these siblings expected that the missile launched from the Luan Feng Hao was not intended to attack the merfolk, but to report back to the outside world!
Xuanyuan Changfeng was quite astute. He knew that entering such a strange area was extremely dangerous. Even if they couldn't get out alive, they had to find a way to get the information from inside to the outside world so that the outside world could bring the correct countermeasures.
Therefore, he arranged for a family disciple to record all the situations from before they entered the strange sea area until now. He then compiled this information and videos and stored them on a hard drive.
Just now, when the battle reached its climax, Xuanyuan Changfeng signaled that family disciple. So, that family disciple placed the hard drive and a launching device at the warhead of the missile.
He activated the missile in the control room. Due to the failure of all navigation systems within the barrier formed by the ruins of the overseas immortal, the family disciple directly used inertial guidance, directly inputting into the missile's program to make the missile fly in a straight line in one direction.
The missile, relying on its fuel and inertia, flew directly away from the island. After flying for 100 kilometers, before its fuel ran out, it ejected the launcher and the hard drive placed at the warhead.
The launcher, attached to a parachute, slowly descended onto the sea surface, then automatically contacted the satellite in the sky and began transmitting the data.
