The road leading to the upper level of the city was heavily guarded. There were many sentries and packs of hounds patrolling the area. The hounds of this era had been improved generation after generation. Their sense of smell and hearing were unparalleled. Even the slightest movement could not escape their detection.
The hounds were easy to deal with because they needed their sense of smell and hearing to detect movement. As long as one's breath did not leak out, these creatures would not be able to detect movement.
There were also many big-eared bats flying in the sky. These natural radar creatures were the nemesis of all kinds of stealth techniques. They could emit low-frequency sound waves and use the reflection of the sound waves to explore the environment. It was an active detection method. As long as there was an individual, it could not be avoided.
Luo Kai pondered for a while before coming up with a solution. It was not difficult. The principle was the same as the detection of radar. He only needed to reduce the reflection area of the sound waves. He either needed to find equipment that could absorb sound waves or use low-frequency sound waves to disturb the bats. He did not have time to find any equipment, so he directly used his throat to simulate low-frequency sound waves to disturb the bats' perception. The bats were very sensitive to sound waves. They instantly lost their sense of direction and bumped into each other.
He could even simulate high-intensity low-frequency sound waves to directly kill these creatures, but there was no need to do so.
The only problem was that the Tuoba family was too big. The top of the mountain was filled with all kinds of houses and castles. There were three rings in total. The innermost ring even reached the belly of the mountain. There were tens of thousands of family members living in the outer and middle rings. There was even something in the inner ring that made Luo Kai feel dangerous. As one of the oldest aristocratic families of the human race, although the Tuoba family had not produced a Saint for a long time, they still had a very deep foundation. There were more than a dozen physical teachers and three high-level physical teachers in the family. Luo Kai did not dare to expand his spiritual power to sense for fear of being discovered by powerful people.
He shuttled through the night. When he passed by a small garden, he saw a familiar person. It was a girl about 14 or 15 years old. Her pretty face was like a flower, and her big eyes were twinkling. At first glance, he knew that she was a naughty, willful, and daring girl.
The girl was Tuoba Ye's daughter. Luo Kai had met her when he first came to Shang Jing. She was still a little girl then, but now she had grown into a slender and elegant young lady.
Following the girl, he finally felt Tuoba Ye's breath. The old man was reading in a study.
The young girl pushed the door open and entered. She said coquettishly, "Daddy, I'm so bored. Can you take me out to play tomorrow?"
Tuoba Ye turned around helplessly. "I've only been here for two days and I'm already bored."
The young girl went forward and hugged his shoulders, complaining, "You're not allowed to go this way, you're not allowed to go that way, you're not even allowed to leave the door, it's so boring!"
Tuoba Ye patted her little hand and spoiled her: "Okay, tomorrow your cousin will take you to the Sky Combat Army's training ground. You can try flying with the wing suit, but let's agree that you can only fly in the training ground. You are not allowed to leave Cang Nan Manor."
"Okay, I'll go tell my cousin!" The young girl's big eyes turned, and she ran out with a flick of her long hair.
Tuoba Ye smiled and turned his gaze back to the desk. On the desk was a detailed military map. The central war zone relied on the Yunling Mountain Range to set up layers of defense, trying to minimize the number of Moonbeasts that infiltrated the territory. However, most of the defense lines had been lost, and the Moonbeasts had penetrated deep into the Chuyun Pass.
Unlike the land Moonbeasts, the Moonbeasts did not engage in large-scale battles with the human army. Instead, they infiltrated the human army. During the day, they were nowhere to be seen, but at midnight, they would pass through the layers of defense lines and directly attack the cities where the population was concentrated. This kind of blitzkrieg nature had caused the human army to have no effective way to counterbalance the Moonbeasts for a long time. The only way to contain them was to use the Sky Combat Army, which could also fly. However, the Sky Combat Army was like a group of dragons without a leader, falling into chaos.
While Tuoba Ye was frowning, Luo Kai was also in a dilemma outside. He was hesitating whether or not to go in and meet him. He had no intention of getting too involved, but it might be better if he secretly helped to kill some of the evil cult's physical masters.
At this time, an old man with a green beard slowly walked over. His aura seemed to be low, but it was actually very excited. It was somewhat similar to Tuoba Ye's aura, but it was much deeper. Without a doubt, he was another high-level physical trainer.
Luo Kai did his best to retract his aura, completely blending into the darkness.
Tuoba Ye also felt it, and hurriedly stood up to welcome him. "Third Uncle, why are you here?"
"We haven't seen each other in a long time, so I came to talk to you."
The old man walked into the study and looked at the map on the desk. "Why, have you started to study military affairs?"
Tuoba Ye scratched his head and laughed dryly. "Third Uncle, you know that I'm a boorish man, so I don't understand much."
The old man's somewhat cloudy eyes shone brightly. He smiled and said, "If you are a boorish man, then there are no smart people in the Tuoba family. I'm going to let you be the general of the Sky Combat Army. Do you dare to accept?"
Tuoba Ye was startled and hurriedly refused. "I live in Shangjing all year round. After graduating from Shangjing University, I directly went to the Body Arts Association. I've never participated in military affairs, so I can't take on this heavy responsibility."
The old man sighed. "Little Ye, you don't need to be modest. We old people are all old. In the younger generation, only you have reached the middle level. In the future, there is no doubt that you will become a high-level physical master. This heavy responsibility will be on your shoulders sooner or later."
Tuoba Ye hesitated and carefully asked, "Is this grandfather's idea?"
The old man shook his head. "Big brother is focused on curing your third uncle, so he has no time to care about these things. However, we can't just ignore it. I've discussed with a few old people, and we've preliminarily selected four people. The other three are your uncles, and you are the youngest, so I think you are the most promising."
Tuoba Ye bitterly smiled. "Thank you for your appreciation, Third Uncle. In fact, none of us can take on this heavy responsibility. We should think of a way to cure my third uncle."
The old man frowned and didn't say anything else. He stepped forward and patted Tuoba Ye's shoulder, then turned around and left.
Luo Kai looked at the old man's back from outside, and doubt arose in his heart. This old man's seniority was so high, and he was clearly in his twilight years. However, the feeling he gave him was very dangerous, so much so that he was not inferior to those old lamas of the Heavenly Thunder Palace.
Everything has its ups and downs. Generally speaking, a physical master's lifespan had already reached two to three hundred years old. Before two hundred years old, they were considered to be in their prime, and after two hundred years old, they would enter their twilight years. Their body's functions would decline little by little, and it was an all-round aging process until they became an ordinary old man and completely died.
Nothing could avoid this process of turning from prime to decline. Therefore, an older high-level physical master actually didn't have much fighting power, so it shouldn't arouse his vigilance.
Inside the room, Tuoba Ye also deeply frowned. Currently, the Tuoba family still had three high-level physical masters. Other than Tuoba Sheng, who was the Prince of Jingnan, there was also this Third Uncle and one of his uncles. After the two old men entered their twilight years, they went into a state of seclusion. They wholeheartedly cultivated in seclusion, looking for ways to advance or extend their lifespan. They didn't care about anything else.
However, these days, his grandfather, who should have been handling matters, didn't care about anything. Instead, it was Third Uncle and his uncles who went everywhere to take care of reorganizing the Sky Combat Army. Other than that, many of the older physical masters in the clan were very active, and instead made the younger generation of physical masters a mere figurehead.
The reason why he had such doubts was because before he returned from the Heavenly Thunder Palace, Tuoba Xiong had said that there was something wrong with the lamas of the Heavenly Thunder Palace. The evil cult was most adept at bewitching people's hearts. He was afraid that some people had already colluded with the evil cult.
Just as he was pondering, an indifferent voice suddenly reached his ears. "The remaining monks of the Heavenly Thunder Palace have already become the claws and teeth of the evil cult. Now, the evil cult's elites have all come out and besieged the Tuoba family. Soon, they will make their move!"
