On the side of the Killing Dynasty, Li Xuetao was intensively preparing to supervise the defense work in various places.

Speaking of defense, it has to be mentioned that although the palace building is imitation of the Tang Dynasty, it is integrated with modern style, so it is extremely defensive.

The whole city is a rectangle, the total length of the city wall is about ten kilometers, in order to avoid the city gate directly exposed to the enemy's attack, also build a city wall outside the city gate, form a small area of defensive urn city, once the enemy enters here, it will be besieged on all sides, like a turtle in the urn.

However, the Killing Dynasty is located in the middle of nowhere, and no one usually cares about it, except that this city is hidden in the deep mountains, Li Xuetao also set up a chaotic formation outside, and ordinary people want to invade, but they have been lost in the mountains before they find the city.

In the imperial city, there is also a strict defense system, adopting a three-layer overlapping arrangement, with a total depth of 128 meters of city walls, and opening up 108 small holes for garrisoning soldiers and storing military supplies in the city wall, which are not cold weapons such as bows and crossbows in the past, but heavy machine guns that can strafe outward at 180 degrees, and there are water tanks, water filling holes and multiple gates that can block the enemy above the holes to defend against fire attacks. The dry gate, the water gate, the fort, the enemy platform, the sluice, the lamp tower and other facilities to deal with the enemy are complete, these are all made of reinforced concrete, very solid, not so much a city, but a military base.

However, although the defense of the imperial city was tight and tight, if the enemy was Li Chen, it would be very dangerous, because when the imperial city was built, Li Chen also participated in it, and even many defensive offensives were still his opinion.

War is undoubtedly terrible, and even more terrible is the civil war.

This time, the Killing Emperor encountered a real enemy, a powerful enemy who knew them well.

Li Xuetao was worried about the enemy's attack on the one hand, and Yan Xiaokai on the other hand, although she knew that Yan Xiaokai would not be in any danger at this moment, and he would not be hungry and freezing, but he and his father were like this, but it was definitely not what she wanted to see.

Just when she was in a mess, a subordinate's voice came from the intercom system: "Report, there is an emergency." ”

…………

The border between the western province and Russia has a unique karst topography, with peaks and jungles, numerous canyons, extensive caves, and streams!

In a dense forest outside the walls of the Killing Dynasty, a young man was hiding in a towering tree, slowly looking around, while looking down and sketching something!

This man is none other than Yan Xiaokai.

Hey, wasn't he imprisoned in the secret chamber of the Hall of Eternal Life? Why is it here again?

It turned out that after being trapped in the Hall of Eternal Life, Yan Xiaokai first sent his location to the base, and then began to rest, and when he slept enough, he began to practice.

However, the Wushang Heart Method requires men and women to practice together in order to have a significant effect, Li Yu locked him here, but did not arrange a maid for him, Li Xuetao was also nowhere to be seen, and after practicing alone for a while, he felt that it was not interesting at all.

When he was bored, he looked at the antique calligraphy and paintings on the wall, and he found that one of the paintings was exactly the same as the one he had seen in the hall above. This discovery made him curious, so he wanted to take down the painting to see, who knew that this painting seemed to be embedded in the wall, and he couldn't take it down at all, so he could only turn it, and after turning it around a few times, the whole room moved, and then returned to its original position, and the appearance of the hall of the Hall of Eternal Life appeared in front of him.

Yan Xiaokai, who had regained his freedom, slipped out of the Hall of Eternal Life, and then took a turn in the imperial city, with his skills today, he naturally would not attract anyone's attention.

After turning around the various places, he unconsciously crossed the walled city, ran outside, found a hidden place to hide, and began to sketch out the topographical map he had written down in his mind, ready to send it back to the base.

When he finally drew the map and passed it back, and then planned to go back to the Hall of Eternal Life to lurk, there was movement in the distance.

At the foot of the mountain in the distance, a platoon of off-road convoys was heading in this direction.

Inside a heavy-duty off-road vehicle in the lead, driving is a middle-aged man, next to a delicate.

This man and woman are undoubtedly Li Chen and Qin Xianglan.

The scenery of the mountain along the way is incomparably beautiful, with countless peaks on both sides, like a natural barrier, as far as the eye can see, the blue sky and clear water, the green trees and forests, and a qiē landscape are in full view, just like a landscape painting.

However, Qin Xianglan didn't have the heart to watch these, and saw that Li Chen had been walking around the mountains with the convoy, and there was no end to going around, so she couldn't help but say, "My dear, how long will it take to get to the ground." ”

Li Chen freed up a hand, stroked her plump legs, and said calmly: "Don't worry, we have now entered the realm of the Killing Emperor Dynasty, but there is a large formation set up by my niece outside, and we must follow the steps to go around, otherwise not only will we not be able to pass, but we will also be trapped alive in this mountain." ”

Qin Xianglan was silent, because she knew very well that there were some things that could not be rushed.

Seeing that she was silent, Li Chen asked again, "Have you arranged all your people?" ”

Qin Xianglan nodded and said, "Well, I have ordered them to be under your command according to your orders, and let you be fully responsible. ”

Li Chen asked, "How did you explain this trip to them?" ”

Qin Xianglan said: "It's very simple, I told them to come here to rob a hidden rich family. They are all the most desperate masters in the Hongmen, let them play the striker at that time, first solve your eldest brother's gang, and then you go to your time machine, and I will search for our gold and silver treasures!

Li Chen was slightly stunned when he heard this, and asked, "Are you really not going back with me?" ”

Qin Xianglan shook her head, "I'm used to modern civilization, such a backward era, I feel terrible when I think about it!" ”

Li Chen sighed and finally said no more.

By the time they reached the halfway point of the mountain, the sky was beginning to turn gray and the air pressure was very low, and it was clear that a heavy rain was coming.

Li Chen stopped the car, got out of the car and looked around for a while, then said to Qin Xianglan: "Before dark, we can only hide around here, and wait until it gets dark before making plans." ”

…………

Hearing the alarm of the intercom system, Li Xuetao hurriedly pulled down the microphone and asked, "What's the situation, is the enemy coming?" ”

One said: "Report to the princess, there is no enemy attack yet, but our intelligence network has a news that a group of people from unknown sources and forged identities got off the plane in Western Province, and also purchased more than a dozen military off-road vehicles, we suspect that it is Li Chen's group of rebellious ministers and thieves." ”

Li Xuetao frowned, it seems that Uncle Huang is really going to attack in a big way, and he has already gone up the mountain at this moment!

Looking up at the sky, there are dark clouds, and it is obvious that it is about to rain heavily, in such weather, will the emperor choose to attack?

After a deep sigh, Li Xuetao shouted: "Pass the order, and all defenses will be upgraded to special alert!" ”

"Yes!" There was a loud sound of promise in the intercom system.

Li Xuetao returned to the imperial city, entered the main hall, and saw his father sitting on a chair in contemplation, so he said: "See my father!" ”

When Li Yu saw her daughter, her frowning brows finally relaxed, and she said with a kind smile: "Xue'er is here, come quickly, come and sit down!" ”

Li Xuetao rushed over and sat down beside his father, and then said, "Father, the emperor's uncle may have already gone up the mountain." ”

Li Yu nodded, "I know, I've heard about it just now!" ”

Li Xuetao raised his eyes to look outside, and said slowly: "It's okay if Uncle Huang doesn't come, if he really wants to attack the city, I must make them look good!" ”

Li Yu didn't dare to be optimistic, and his brows furrowed again, "Your imperial uncle's personality, no one can know better than me." He has a smart head and a lot of tricks. Since he dares to come, he naturally has all the preparations, Xue'er, you must not hold it up! ”

Li Xuetao was slightly frightened, and said in a solemn voice: "My father has taught me a lesson, and I will deal with it carefully." ”

Li Yu nodded slightly, and said worriedly: "With the crystal energy of the batch of dinosaur eggs you sent back, the time shuttle has entered the final stage of research, and at such a critical moment, your imperial uncle actually came to attack, it is really not the right time." ”

After Li Xuetao hesitated for a moment, he asked, "Father, can we really go back?" ”

"Of course!" Li Yu said slowly: "We can already distort the space enough to create a local gravitational field, just like a bagel that can be presented in any size. The gravitational field forms a circle around this bagel so that space and time can be bent tightly into the past. The time of each phase in the time machine qì will be generated in a certain space within the bagel to propel a high-quality object in a high-speed circular motion. This energy field is the external gravitational force, which can quickly travel from one place to another, or from one moment to another. ”

Li Xuetao was stunned when she heard it, because although she felt very powerful, she couldn't understand it at all, and she couldn't imagine that her father from ancient times had become a modern scientist.

Seeing her expression, Li Yu couldn't help asking, "You don't understand, do you?" ”

Li Xuetao nodded, "I really don't understand!" ”

There was a hint of a smile on Li Yu's face, and he patted her weak shoulder and said, "You don't need to understand, you just need to know that your father will take you home!" ”

Hearing her father's words, Li Xuetao did not make a sound, because she was extremely conflicted in her heart, going home used to be her wish, but now she really wants her to go back, but she is reluctant, because she already has concerns in her heart.

It would be great if the officials could go back with me!

Li Xuetao thought so in her heart, but she understood that Yan Xiaokai would not go back with her.

Alas, it seems that only one step can be taken, and one step can be seen.

Li Xuetao sighed silently, and then began to discuss with his father the details of defending against the emperor's uncle's attack.

It's just that neither of them noticed that at this moment, there was a person lying on top of the beam, listening to their conversation word for word......
