When Qin Changqing arrived at the central building, Xitu had already been waiting there for a while. Xitu ordered coffee for him and immediately got straight to the point after he sat down.

"I'm planning a trip to Fort Kaher."

Qin Changqing frowned and said disapprovingly: “This is too dangerous for you.”

Xitu sighed, shook his head and said, "But those students haven't come back yet. There are too many of them. We need to get them out. The other police officers are all psychics. They will die if they go in."

"Can't robots be allowed in?" Qin Changqing asked doubtfully. Although mania is contagious, it is limited to creatures with superpowers.

Xitu shook his head gravely. "It's no use. For some reason, when General Kah had just passed away, drones could still enter that place. But after a while, they could no longer receive any signals. That's why Fort Kah has become increasingly mysterious."

This surprised Qin Changqing very much. He had previously thought it was just due to mania.

Xitu paused after he finished speaking, and glanced at Qin Changqing with slightly round eyes, and after a while he hesitated and said, "I want you to come with me. I wonder if you..."

Qin Changqing raised his eyebrows. He did have the idea of going to Kah Castle in person, but he didn't expect that Xitu would send an invitation before him.

"Do you want to go in and save those students?" Qin Changqing took a sip of coffee.

"It's not just for this reason," Xitu chuckled a little embarrassedly, "I'm actually a little curious about what's inside Castle Kahe."

Qin Changqing wanted to laugh, "Are we just going?"

"I will bring a guard with me, you can do whatever you want." Xitu thought of the person who said the secret words to him in the police station. He thought that Qin Changqing was not an ordinary person and would definitely not go alone.

After a moment of silence, Qin Changqing finally said, "Give me some time to think about it."

"Okay, contact me after you've thought it over. I'll also make some preparations first." Xitu was very excited that he was not rejected directly, and he quickly stood up and said goodbye.

Qin Changqing sat alone for a while, thinking about how to tell Lan Sinian about this.

After thinking about it all the way back to the palace from the Central Building, he decided to tell Lan Sinian directly.

Every day after school, Qin Xu would go back to the palace and do his homework first. Some of the homework was assigned by his current school, while others was assigned by Qin Changqing. It would take him about one to two hours to finish it. After finishing, he would ask his father to correct and grade his homework. The father and son were quite happy to interact with each other.

Perhaps because he did not grow up with his parents, Qin Xu was much more sensible than other children, and his academic performance was always among the best. However, the Empire textbooks were still very difficult for him, and his grades were almost at the bottom at the beginning. Fortunately, he was very smart and hardworking, and his teachers were very attentive to him, so his grades were slowly improving.

"Xiao Xu, Dad may be away for two days. Can you stay in the palace?" That day, Qin Changqing finished correcting his homework, touched his head and discussed with him.

Qin Xu was stunned. "Where is Dad going? How long will he be gone?"

"It's on Emperor Star, not too far away. I'll be back in two days at most. I promise, okay?" Qin Changqing felt very guilty towards his son, and he thought about it for a long time before saying this to him.

"Well, okay then, Dad, you must come home early." Qin Xu finally agreed, but he was so sensible that Qin Changqing felt distressed.

"Okay, I promise."

Lan Sinian was not surprised by his decision and agreed directly, "Take Hanhai with you."

"No, it's too dangerous," Qin Changqing refused. Kahe Castle was too dangerous for people with special abilities. Xitu had decided to go on his own, and since they were all adults, Qin Changqing wouldn't take responsibility for his decision. But Hanhai had gone into that dangerous place purely to protect him, following Lan Sinian's orders. Qin Changqing didn't have the nerve to do that.

"Take him with you, or don't go, you can choose one." His Majesty the Emperor was also very easy to talk to and gave him two options.

Qin Changqing: "..."

After Lan Sinian finished teasing him, he saw that he looked unhappy and asked with a smile, "Are you angry?"

"You know I don't want anyone to get hurt because of me or because of the things happening on Earth." Qin Changqing sighed.

"I don't know." Lan Sinian shook his head rudely. Qin Changqing wanted to defend himself, but he saw Lan Sinian's sapphire blue eyes staring deeply at him. "I only know that since I brought you to the empire, I have an obligation to give you and the little cub comprehensive protection. You are my responsibility."

The look was so deep, so deep that it seemed to penetrate into one's heart. Qin Changqing's heart skipped a beat, and he subconsciously turned his gaze away from him.

Lan Sinian was extremely persistent in this matter, and the conversation ended with Qin Changqing's compromise. Whether the Earth could survive and prosper in the interstellar era in the future was closely related to him. Now a huge cake was placed in front of him. It was impossible for him not to be tempted.

Seeing that he had compromised, the Emperor put on a smile again and said with a smile: "Han Hai has received special training. His combat capabilities in other aspects are not inferior to his supernatural attack capabilities. You can rest assured."

How could Qin Changqing be at ease? He thought about it and took out the big box he brought with him.

The box contained some daily necessities for him and Qin Xu, but more were gifts from his comrades. A group of rough-hewn men who had fought through the hail of bullets wouldn't have given him anything delicate and exquisite. Instead, to his amusement, they presented him with a monotonous assortment of weapons, including a revolver from Luo Yuhuan.

Qin Changqing raised an eyebrow and pulled out the ornately crafted revolver. It was a famous Colton Python, discontinued over twenty years ago. It was more collectible than practical, likely part of Luo Yuhuan's collection. Luo Yuhuan was a huge gun collector, so he must have felt bad when he gave it to him. Qin Changqing couldn't help but smile as he recalled their time together on the battlefield, embroiled in bloodshed.

In addition to the gun, Luo Yuhuan also gave him twelve bullets. Qin Changqing thought about it, took out six of them, and asked Qi Feng to ask him for a favor.

"The bullets for this type of mechanical firearm are easy to make, just leave it to me." Qi Feng agreed readily.

"I want to fill some cinnabar in the bullets. Can you ask me if it can be added in?" Qin Changqing felt that his idea was a bit whimsical, but he had to give it a try.

Qi Feng was a little surprised, but he still agreed without hesitation, "Okay."

In addition, Qin Changqing also asked him for a sword used by the imperial guards. For the people in the interstellar space, this kind of sword is more decorative than practical, but Qin Changqing had used it to kill those black monkeys directly, so it was still very useful.

Because it was a decorative item, the slender blade of the sword was engraved with many intricate and beautiful intaglio patterns. Qin Changqing asked Qi Feng for some special adhesive and applied a layer of cinnabar. Cinnabar is a pigment, and after he applied it to the sword, the originally bright silver-white blade was paired with the cinnabar-colored patterns, making it look even more eerie but also more gorgeous. Qin Changqing sighed inwardly and sheathed the sword.

Even after making these preparations, he still felt uneasy. He thought about it and suddenly remembered the ghost movies he watched when he was a child. He had an idea and quickly asked Qi Feng to find him a lot of cotton thread, and then soaked it in cinnabar. After waiting for a night, he took it out and saw that the long cotton thread was also dyed with a uniform cinnabar color, which was very beautiful.

After doing all this, Qin Changqing contacted Xitu.

"I've decided to go to Kahe Castle with you. When do we leave?"

"Really?!" Situ seemed very excited and said incoherently, "We'll go right away. No, no, I need another day to prepare! How about the day after tomorrow morning? We'll meet at the Central Building, which is the closest area to Fort Kaher!"

"No problem." After finishing the call with Xitu, Qin Changqing took a deep breath to calm his slightly excited mood.

The night before leaving for Fort Kaher, Qi Feng finally delivered the hastily made revolver bullets. "The craftsman who made them has remixed them and improved the ammunition a bit. He even left a small amount of space at the bullet tip to fill it with cinnabar. It should be fine."

"Thank you." Qin Changqing took the bullet and weighed it, feeling good.

"This is what I should do. You're welcome." Qi Feng smiled and shook his head.

On the morning of the appointment with Xitu, Qin Changqing got up before dawn. He first prepared things for his son to take to school, and then went to the small kitchen to prepare breakfast for the whole family.

Lansnian got up later than him. When he got up, the table was already filled with Chinese special breakfast, boiled eggs, soy milk and fried dough sticks.

"So early?" Lan Sinian leaned against the kitchen door, admiring the queen wearing an apron openly. Well, after his queen put on that cute little piece of cloth, her beauty reached a new level. Lan Sinian once again confirmed that the queen must be seducing him. It seemed that she thought he was not trying hard enough!

Qin Changqing was busy cooking tofu pudding and had no time to pay attention to the yellow waste he had been dumping since early in the morning. He put the seasoning in place, looked back at him and said seriously, "I'm going to Castle Kahe today. I'll trouble you to take care of Xiaoxu for two days. Remember to pick him up from school on time this afternoon."

"Well, no problem, but how are you going to repay me?" Lan Sinian touched his chin and looked him up and down. He must keep this apron.

Qin Changqing glanced at him, "Didn't you say I was your star? Why do you want a reward for doing such a small thing for me?"

Lan Sinian narrowed his eyes and looked at him for a while, with the corner of his mouth slightly raised, "Okay, I am willing to give you everything I have, my beautiful Queen." We can settle the payment later.
