To the southeast of the royal capital, hundreds of selpoles away, stands a palace.

The design of the palace is based on a simple, elegant style, although it is not as ornate as the royal palace, but it is still beautiful. The Ebel Palace was originally used by the queen to recuperate on vacation, and when the queen was not here, it was also a famous tourist destination.

However, in the dark of night, by the sparse lighting, this is just a somewhat beautiful palace. What's more, those black-clothed soldiers have always firmly occupied the main routes out of the palace, and Colonel Richard has already given them a death order, because there is now a very important existence in this palace for the progress of Richard's plan.

"It's really a strict precaution...... "After all the hard work, tiptoeing to lurk in a corner next to the palace, Nair held a portable guide lamp that emitted a faint light in his mouth, and spread out a map with both hands, "I'm in this northeast corner now, and the center of the palace is...... The patrol route here ......"

"It should go around to the south, there is a gap of about fifteen seconds between the two groups of patrolling guards, and in that time, try not to make a sound, and cross a distance close to 57 sub-moments, no problem, right?" The girl's voice was cold behind her back, so frightened that Nair almost screamed. He jerked his head back and found a familiar face looking at him expressionlessly.

"Scared the hell out of me...... Suddenly speaking......" patted his chest, and Nair stood up in shock, "Is that you?" How did you end up here? ”

"The plan of action has changed temporarily." Fei briefly answered Nair's question, "It's you, why are you still hanging around outside this palace after a day has passed?" ”

"Well...... "Nair scratched his head a little embarrassed, "I thought I could understand these roadmaps when I first saw them...... But that's not the case at all! The connections and symbols between these patrol routes, as well as the relationship between the entry points of each other...... I haven't figured it out for a long time......"

"We didn't take that into account." Fei sighed helplessly, "Indeed, it is impossible for ordinary people to understand such a complex thing quickly...... But you're a journalist, well, according to Helriga, you should have mastered a lot of things that you shouldn't have mastered......"

"What's that subtle statement...... Forget it, since you're here, you can't just come to see the fun, right? ”

"Of course not." Fei smiled, "Let's go, it's time to exchange routes soon." Take out that purple bottle, hold it in your hand, and be ready to drink it. ”

"What...... I...... Alas......" Watching the girl walk towards the inconspicuous little door to the north, Nair sighed helplessly, and had to follow.

"Take it easy, uncle." Fei stared intently at the soldiers who were napping at the door, "The shift change of this group is very slow, and there is no threat. ”

"Uncle...... I said you...... "Nair was angry, he was still a young man who had just reached his thirties, was he misunderstood as an older uncle just because he usually neglected to tidy up his appearance?" But even so, looking at the girl's young and seemingly nonchalant expression, Nair began to feel that if he really defended, he really lost in a sense.

Coughing slightly, Nair, who was trying to change his mood, heard the girl's question again: "Words...... This palace ...... What is it for? ”

"You know what?" Nair first asked rhetorically.

"Helliga said...... It's like a queen on vacation. Fei tilted her head, "But I always feel that if it's just a vacation place, some places seem too redundant." ”

"Because he just said the main function of the palace." "As the name suggests, the Imperial Palace is a temporary residence for the royal family when they leave for their tours, but under the Kingdom's policy of resisting excessive luxury, the Imperial Palace is also used to receive foreign guests of sufficient honorable status, and some areas are open to visitors......"

"That's right...... It makes sense. When she had been observing the palace for a long time, Fei couldn't tell the purpose of some of these facilities and buildings, and after listening to Nair's words, she immediately understood what was going on, "Look, the shift change over there has begun." ”

Nair looked in the direction that Faye was pointing, and around the two lazy soldiers appeared two other Intelligence Division soldiers in the same black uniforms, who seemed to be communicating something, completely oblivious to their surroundings.

"It's now." Fei succinctly told Nair, "According to the observation, they will talk together for about 1-2 minutes, and we will now go directly from here to the nearest wall and ...... with a hook claw" After speaking, Fei also deliberately stared at Nair's haggard face: "Are you okay?" ”

"Of course, no problem." Nair blew his beard impatiently, what kind of reporter would he be if he was stopped by this difficulty. Fei also seemed to understand what Nair meant, and turned her head to start preparing.

For the next minute, no one said anything, and if they were discovered at this time, a clash with multiple agents would inevitably cause a lot of commotion, which would attract more guards and strengthen the internal defenses. Even though the girl next to her was skilled enough to quickly take everyone down without causing any movement, there were still other patrolling soldiers who noticed something was wrong and strengthened their vigilance - in that case, all the previous preparations and efforts would be undone.

Fortunately, the two finally came to the foot of the high wall without danger, and Fei had already prepared the hook claw in his hand, and threw it skillfully, and soon there was a sound of gentle biting.

"It's sturdy, that's fine." Fei pulled the rope hard, nodded in satisfaction, and then turned to Nair: "Drink that potion, you go up first." ”

“…… Good. At the critical moment, Nair, who understood things very well, did not ask about the effect of this potion, nor did he ask more about why he went in first. He drained the potion from the bottle in one gulp, wrapped the safety rope around his waist, and then stepped on the protrusions in the wall, advancing towards the wall little by little.

The process went smoothly, and it didn't take long for Nair to climb the walls several centimeters high. He looked at the dark ground inside the walls, took a deep breath, and leaped down.

"Oops...... The moment my waist ......" landed, the sudden spraining pain in his waist made him take a breath of cold air and cry bitterly, "It seems that I am really old......"

"Yes, you are indeed an uncle." The girl landed lightly beside Nair, without splashing a trace of dust, "The action can be said to have turned out well...... Until the end of their shift change, they didn't notice that two people had sneaked in. ”

"It's really long-winded." Nair complained as he touched the camera next to him, but fortunately it didn't fall off, "What about after that?" ”

"Hiding in the bushes over there, I need some time to observe how the soldiers in front of me are patrolling." Fei was also unambiguous, "Wait for my signal, you can wait here for a while." ”

"......" Nair, who wanted to say something, looked at the girl who had already begun to move towards the soldier patrol center in a dead end, but finally couldn't say it.

P.S: I've received some feedback, so I'll post a popular science article on the knowledge related to the work tomorrow...... Because there are a lot of words, you need to sort it out yourself, so tomorrow's update is probably going to be a pigeon...... If you have time on Friday, you can make up for it, and if you don't have time, you can only cut it......
