The Chinese government was the first to ask Lu Weixian's opinion.

Without any hesitation or any strings attached, Lu Weixian agreed to the requests of various governments.

Lü Weixian never had the idea of destroying himself, and his original intention in creating this wall defense system was to help mankind re-establish a civilization on the ground. After verifying the feasibility of his plan in the process of assisting Huaguo to recover Huajing, he has decided to selflessly contribute the plan he has devised with great effort to all mankind, hoping to help people in other countries better recover their cities.

When the world learned the contents of the report and truly understood Lu Weixian's whimsical ideas, they could not help but feel sincere admiration for his genius thinking.

It turned out that the reason why the city wall designed by Lu Weixian had such a strong ability was that he connected the city wall with the entire city and transformed them as a huge magic crystal circuit.

The Great Wall that surrounds the entire Huajing City is actually an output end, and the carefully calculated buildings in the city are equivalent to the mosaic holes of the magic crystal circuit, and the main road that has been transformed is the path for transporting energy.

When the monsters crashed into the city walls, they did not hit dirt and stones in the ordinary sense, but a super-large "earth magic" that was composed of countless earth magic combined into a whole.

If there is any only drawback of this design scheme, it is that the consumption of magic crystals is too large, and those "mosaic holes" are not decorations, but giant beasts that devour magic crystals, and a generator that can convert magic crystal energy must be placed on each building to provide huge energy to the city wall.

Of course, if necessary, you can also use the Earth Awakened to replace the generator to supply energy, but the number of Awakened is very large, and at the critical juncture of the reconquest of Huajing City, Lu Weixian used this method.

Compared to being able to recover the city, even if it consumes a lot of magic crystals, it is nothing, when the countries understand through Lu Weixian's genius idea, they have modified it according to the actual situation of their own countries, and for a time various countries have launched a vigorous operation to recover the city.

Humans can finally be liberated from the darkness of the underground base, and return to the surface and return to the city they have built.

After that, Lu Weixian also continued to contribute his own strength to the country, and successively designed different city wall defense systems for the three cities of Huaguo.

They are:

The Magic City in the east - the Blue Sea Pearl Tower, taking advantage of the geographical advantage of the Magic Capital City's proximity to the sea, the Blue Sea Pearl Tower can absorb water vapor to create a large water curtain that surrounds the entire city, and all the demonic beasts that enter this water curtain will be weakened by a certain strength, and the degree of weakening can be adjusted according to the output of control energy.

The south side of Aries City - Nanli Fire Tower, which is a magic tower that towers in the center of Aries City, can inspire five types of powerful fire magic attacks according to different types of magical beasts, this magic tower can be flexibly controlled by the awakened, and it is especially threatening to units in the air.

In the west, the Potala City, the Aeolus Palace, similarly takes advantage of the abundant wind energy in the surrounding area of Buda City, and the Aeolus Palace can create a large number of wind whirlwinds around the city, which can cause all the magical beasts that step into it to be blown away or cut into pieces.

Lu Weixian did what most of the awakened people couldn't do as an ordinary person, and his contribution to Huaguo was unparalleled, but it was a pity that God was jealous of the talent. After Lu Weixian designed the defense system of the last Potala City, he unfortunately fell seriously ill due to overwork, and unfortunately passed away not long after.

After Lu Weixian's death, Huaguo also used many talents with talents in this area, but unfortunately no one could reach the height of Lu Weixian. The defense systems designed by those designers were basically modified according to the design manuscripts left behind by Lu Weixian, and their defensive power was far inferior to that of the Four Cities.

Until now, these four cities, which have been personally designed by Lu Weixian, are still the safest cities in China. These four cities have attracted countless human settlements, not only Chinese people, but also a large number of foreigners, and the four cities have become the four largest human settlements in the southeast of Zhongzhou.

......

......

As the altitude gradually decreased, it didn't take long for the Qinglan to dock steadily at the outskirts of Huajing City.

In the southern part of Huajing City, a large area has been cleared in advance for visitors from all walks of life to park their vehicles. When the people of Qinglan Academy arrived, they had already found that there were a lot of magic crystal hovering cars parked here, and there was a large floating ship such as the Qinglan, and the Qinglan was parked in it with a sense of immediacy that stood out from the crowd.

Under the leadership of Cheng Wei, everyone standing on the Qinglan jumped out of the deck and jumped to the ground, although there were also automatic elevators on the deck of the Qinglan, but with the physical fitness of the people present, the height of more than ten meters was a matter of a light jump.

"Hahaha, the person leading the team this time turned out to be you, Cheng Wei, long time no see." As soon as everyone jumped to the ground, three figures immediately appeared in front of everyone, and one of the tall bald figures laughed and opened their hands to "hug" Cheng Wei.

"Oh? Liu Wenlong, is the security of this national conference in charge of the special combat team of your 17th Division? Cheng Wei said in surprise, and at the same time turned sideways, avoiding the overly enthusiastic hug of the bald man named Liu Wenlong.

Liu Wenlong didn't care, raised his hand and touched his shiny bald head, and said with a laugh: "Not only our 17th Division, but also the 5th Division and the 10th Division's special combat team brothers are all security members of the National Conference." ”

After saying this, Liu Wenlong suddenly lowered his voice and said to Cheng Wei mysteriously: "Not only that, I heard that the government also dispatched one of the five teams." ”

Cheng Wei's heart jumped after hearing Liu Wenlong's words, and he couldn't help asking, "Really?" Which one is it? ”

"Don't ask me, there has been no formal explanation from above, and I have limited understanding." Liu Wenlong shook his head and said.

"It seems that this national conference is destined to be uneasy." Cheng Wei's face was worried.

"Don't worry too much, this team may be just a precaution, and I hope there will be no time when this team will be needed in the end." Liu Wenlong said.

"Well, hopefully." Cheng Wei nodded.

"Come on, let me see how the spirits of this year's junior brothers and sisters are?" Liu Wenlong took the initiative to expose the topic, and walked towards the students behind him.
