Standing there pretty, his unique temperament like an iceberg beauty attracted the attention of many people, but no one was close to her.

There was a hint of excitement in Gu Jiayi's cold eyes.

This time Gu Sixin attended the three major music festivals, but she had been there for nearly a month, so Gu Jiayi naturally missed her very much.

Gu Jiayi loves her sister who has begun to move to the international stage and will definitely become one of the most famous pianists in the world in the future.

Of course, there was more or less Du Cheng's volatility between her fluctuations. The plane entered the airport on time. When she saw Gu Sixin walking out of the airport passage, her temperament, which was originally like an iceberg beauty, suddenly changed tremendously, and there was a little sweet smile on her face. When Gu Sixin walked towards her quickly, Gu Jiayi slowly opened her arms.

"Danu."

Not only Gu Jiayi misses Gu Sixin, Gu Sixin naturally misses her only sister very much. She is like a lactation swallow, throwing herself into Gu Jiayi's arms and hugging her tightly.

Du Cheng, Su Xueru and the others were behind.

Looking at the deep sisterly scene, their faces involuntarily showed a knowing smile.

Gu Jiayi came here in a car. Her Porsche sports car could only carry the two sisters. Fortunately, Du Cheng's car was parked outside. After Gu Jiayi and Gu Sixin got on the Porsche, Du Cheng followed Peng Yonghua and Su Xueru.

As for Dong Cheng and the others, they naturally went back on their own.

When we got home, it was already past four o'clock in the afternoon. After Gu Jiayi and Gu Sixin returned to the villa, they went back upstairs, tidying up their luggage while talking about what happened in the past month.

Du Cheng took his mother's wheelchair from Su Hui, while Su Xueru and Peng Yonghua went to pack their own things.

At this time, it was already a bit like the setting sun. The sun in the sky had begun to dissipate a faint sunset light. Du Cheng pushed his mother to bathe in the golden light while telling his mother a story. At this moment, Du Cheng didn't think about anything else.

This time Gu Sixin will stay at home for some time when she comes back, and will join several large-scale charitable actions of the Xinxin Charity Foundation, accompanied by Su Xueru and Peng Yonghua.

Gu Jiayi specially gave herself a day off the next day and spent a day with Gu Sixin.

During this period, Gu Jiayi, Gu, Xin, Zhong Lianlan, Su Xueru and Peng Yonghua also drove to Ningde City near City F, and went to Sanduao, a scenic spot there and had seafood.

Du Cheng naturally wouldn't go with these women's gatherings. The next morning, Du Cheng went directly to his soon-to-finished castle.

In the distance, Du Cheng saw a newly built avenue appearing between Xicheng District and the castle. The avenue is underway for the final construction. The entire avenue is twelve meters wide and about one thousand meters long. Although the scale is not huge, it is still very spectacular.

At the junction of this road and Xicheng District Avenue, two members of the elite group are guarding them to prevent some good people from entering and affecting the process.

Of course, Du Cheng's vehicle was released directly.

Du Cheng drove directly along the flat avenue to the foot of the mountain. There was no need to enter here anymore, because the hill in front was directly dug out of it. Not only did it open out of this avenue more than ten meters wide, the mountains on both sides formed a natural gate, and also formed the only road leading to the valley.

All this is carried out according to Du Cheng's wishes. Here we will build a remote control gate directly to block some curious people. If others want to enter the valley, they can only climb up from the side. Even so, the walls built by the mountain rain will block everyone outside later.

Not only that, Du Cheng will install the infrared sensing system and monitoring system at that time. As long as anyone approaches, Du Cheng can learn about it through Xin'er as soon as possible.

When Du Cheng arrived, Lian Chengchun was supervising the construction team to install the remote control door. The door was customized by Du Cheng from the UK. It is the same as the principle of the elevator door, and it is a triple telescopic type.

The entire electric door is mainly purple and white, and the middle is a bulletproof SLR glass carved with a Bauhinia pattern, which not only gives people a sense of dignity and grandness, but also allows people inside to see what is outside clearly, but people outside cannot see what is inside clearly, which greatly enhances the concealment and safety of the castle.

On both sides of the mountain, dozens of workers were beautifying the walls on both sides and strengthening them to prevent landslides in heavy rain.

Du Cheng did not use the car to park the car, so Du Cheng parked the car directly outside and walked inside.

"Brother Du."

Lian Chengchun had already seen Du Cheng's car, but the door was being installed and he couldn't walk away for a while, so he waited for Du Cheng to come over and said hello to Du Cheng.

"It's almost done. It's a few days to complete the renovation?"

Although Du Cheng did not enter, judging from the budget of the process, the decoration inside is probably coming to an end.

"Yes, Brother Du, it will be completed in five days at most. You can wait for a while. After the door is installed, I will accompany you in and take a look." Lian Chengchun pointed directly at the door being installed and said to Du Cheng.

Du Cheng just nodded and said nothing.

With five days left before the renovation is over, Du Cheng knew that he could almost start his own preparations.

Du Cheng naturally focused on safety in the establishment of this castle. He had already reserved a lot of places on the design draft. He just had to wait for the decoration to finish, and he would do it himself. The entire castle was accompanied by a powerful defense system.

After all, this place will become the most important place for him, Du Cheng, and before it happens, Du Cheng will naturally not be careless.

And if Du Cheng himself did all this alone, it would probably take several days.

Just like this remote control door, after the installation is completed, Du Cheng will modify the remote control door system. He had already asked Ye Mei to help her prepare two sets of eye pupil scanning and certification systems that only important national departments will use. If the modification is made, this sweeping system will be added to the gate. If you enter and exit, you only need to scan the eye pupils.

It took nearly an hour before Du Cheng came to install the entire door. Du Cheng waited for more than ten minutes before the installation was completed. Du Cheng just tried it briefly and walked along the valley passage with Lian Chengchun toward the villa.

The reason why Du Cheng opened this remote valley passage was not only to make his castle more hidden, but also to strengthen the defense system.

Du Cheng reserved several positions on both sides of the mountain wall. Du Cheng had already asked the electrician to keep the line in advance. At that time, Du Cheng would modify some automatic guns and install them inside later. As long as Du Cheng was willing, any dangerous person would definitely die and live when he entered this passage.

The overall valley passage is nearly thirty meters long. In order to make this passage less monotonous, the construction team will also beautify both sides of the passage in the past few days, striving to make everything look very visually impactful.

After walking through the valley passage, the entire huge castle was immediately fully displayed in front of Du Cheng's eyes.

However, what Du Cheng's sunlight fell first was not at the castle, but the large wall nearly three meters high around it.

This wall can be said to have been completed with great manpower and material resources. In order to build this wall in the shortest time, Lian Chengchun directly used the center of gravity to invite nearly ten construction teams to construct the construction at the same time. While ensuring quality and beauty, it took more than ten days to complete it.

It can be said that the number of people participating in the entire castle building is probably over a thousand.

The walls were expanded very wide, completely surrounding the entire castle. Moreover, the places where the walls were built were all the highest points of the mountain, and all the trees next to the walls that were higher than the walls were cut down.

When there are no peaks around, that is to say, even if you climb up the mountain, you may be able to see only the top of the main building of the castle, and you can't see clearly what is going on below the castle.

This was arranged after Du Cheng took half a day to arrange it, which not only greatly improved the concealment of the castle. Even if an enemy climbed the mountain with a sniper, there might not be any good ambush.

This is the real purpose of Du Cheng building this castle, safe and absolutely safe.

Because Du Cheng knew in his heart that if his plan was truly developed in the future, he might establish many enemies. At that time, Du Cheng needed an absolutely safe place, which was also considered a preparation made by Du Cheng in advance.
