"Goodbye Grandma Mo, goodbye Hu'er!" Su Chen touched Hu'er's head, turned around and slowly left.

"Goodbye brother, I will be as powerful as my brother in the future, I will also fly into the sky, just like my brother, I will fly up while standing in the water, so beautiful, my friends want to see my brother." Xiaohu looked up at Su Chen and muttered.

"By the way, Brother Su Chen, can you take me to our school in a few days? The friends really want to see their brother, they all said that if anyone brings Brother Su Chen, then whoever can be the boss of the semester, I really want to ......" The little wild goose pagoda was slapped on the back of the head by Mo Yinxia before he finished speaking.

"Go, *Liwanji, how can I have time to accompany you to your school, and what reason do you have."

"People just want to take Brother Su to meet them, Hu'er has seen Brother Su, they ......"

Su Chen shook his head: "Then there is time another day, Brother Su Chen will take you to see your friends, okay?" However, during this period, the little wild goose pagoda has to read books every day, and after reading the books, Brother Su Chen often takes you to meet your friends, is it okay? ”

"Words count!"

"No backtracking!" With children, it seems that he is living younger, Su Chen smiled self-deprecatingly, and regardless of Grandma Mo's objections, Wu walked out of the library.

However, I am only 20, why do I feel like I am 80 years old in my heart?

Perhaps no one would have imagined that a young man who didn't know anything could stir up the ups and downs of Jiangnan City in a short period of time after returning to Jiangnan City. Even if it's me, I don't believe it.

Five years of memory, fifteen years of knowledge, have made it what it is today, but luck still accounts for a large part of it.

"Su Chen, since you know the answer, why do you still come to me, you must learn to grow up by yourself, learn to find the answer in your own life, find your own answer, and find the answer to Jiangnan City. Remember, the answer is in your own heart. Grow up, kid.

- Miao Sen"

Are they all in their hearts?

Su Chen closed his eyes, was silent for a while, and flew out of the library with the flying ship, flying towards the edge of Jiangnan City.

At this time, Jiangnan City was already surrounded by a thick light film, and from a distance, it looked like a huge eggshell, and each light film junction point was full of flying ships. The transmission channel of the Nine Cities does not use wormholes to transmit, but flies directly, which is not too dangerous.

It's just that the nine cities are from top to bottom, with a span of more than 5,000 meters, and it is difficult to arrange such a high city defense line, and the arrival of the beast clan is densely overwhelming, how to prevent it.

"Convene an emergency meeting!" Su Chen called the four elders, turned around and flew back to the financial building. When they arrived at the conference room, all the dignitaries of Jiangnan City had already gathered.

"This time to discuss the issue of city defense, I hope everyone will express their opinions and close our nine cities, so that the beast tide and the enemy will not advance."

"Build a foundation city and defend the inner and outer cities against land monsters!"

"This plan is feasible, and Lin Ruicheng will quickly mobilize troops to participate in the construction!" Su Chen commanded: "Since there is a beast tide, there must be a lot of birds, and it is not impossible to even jump to the Nine Cities, I don't know what your best plan is." ”

"The various cities are connected to each other, but they are separated from each other, but the city defense is difficult to build, and our armament is insufficient, so we cannot form a complete blockade, and we are still waiting for the city lord to decide!" After a half-ring discussion, someone said something, and all parties agreed.

"The machine shop has set out to build a floating shield!" Su Chen said.

"The cost is too high, the material is insufficient, the technology is low, the rate of lost materials is too high......" the technical department immediately objected.

"How much can be built within the limits of attrition?" Su Chen took a deep breath and asked.

"One...... One...... Not a single piece. ”

"Smack!" Su Chen was furious and slapped the table: "Thirty years after the introduction of the floating shield technology, you are actually ...... You actually told me that I can't build a piece, thirty years of you, what are you going to eat? ”

"Tell the city lord, the floating shield technology was held in the hands of the Great Elder twenty years ago, and it has never been handed over to the technical department, and now it ......" Someone relieved the pressure on the technical minister.

"Find, find it for me from the copying manual." Su Chen immediately ordered.

Five minutes later

"Report."

"Please come in."

"City Lord, this is the floating shield technique obtained from the Great Elder......" The member came to Su Chen with a book in his hand.

"Take it to the technical department, if it can be built, then try to build, how much can be built, how much can be built, how much technology has been turned, I don't know how much is missing, I don't know how much has been changed, if the technology has been eliminated, the R & D department is more attentive to research and development of new products." Su Chen said.

"Army distribution!"

"Our army is now nearly 10 million, and the foundation is built as a city, and the guard sergeants are personally arranged by Lin Ruicheng, preventing birds from attacking between the nine major cities, relying on gradients to arrange the army, the lowest ordinary army is the most, and the ninth city has the least ordinary army, so it is arranged. The elite armies are ranked the most in the ninth city, and they descend in order. ”

Beasts can't fly, but they are the largest group of beasts, so more ordinary sergeants are enough. And most of the demon beasts can fly, and it is not excluded that they can fly to the ninth city, and the flying demon beasts will definitely come towards the ninth city, so only the elite disciples can be deployed.

"In addition, tomorrow morning at eight o'clock in the morning to hold a reception on the prevention of animal tides, the address will be held in the square. All the inspection departments were immediately mobilized to gain a comprehensive insight into the movements of the beasts. ”

"Report!" Li Ruidong of the intelligence department.

"What?"

"City Lord, the beast tide has turned. Toward...... Coming from the southwest, if you walk in a straight line, it will only take three days to reach our city, while other cities will take four days at the earliest...... Could it be ......" Li Ruidong's words were like earth-shattering thunder, and the person who was leisurely and happy at first also felt the pressure at this time.

The meeting reopened, and everyone was gossiping, and more people were going to the technical department, and there was a strong demand for the development of floating shields and the like. However, a group of people who were pressed by Su Chen did not dare to press the technology too much.

For a time, the discussion of urban defense was extremely intense.

At nine o'clock in the morning of the next day, under the colorful description of the Jiangnan city staff commentator, all parties knew that the city lord had a serious matter to announce.

"City Lord, will announcing the beast tide too early now cause panic?" The four elders were beside Su Chen.

"The beast tide is bound to come, and I don't know sooner or later. However, we should always be mentally prepared for everyone, otherwise the sudden arrival of the beast tide may cause greater panic at that time, and now it can be regarded as a precaution. Su Chen replied.

The next qiē became Su Chen's performance stage.

After the people were frightened when they first learned of the arrival of the beast tide, with Su Chen's gradual explanation, as well as various precautions, coupled with all kinds of fierce words, the people eliminated the panic of the beast tide for a while, and instead became fierce and high-spirited.

Su Chen saw that the effect had been achieved, so he shouted: "Now that the beast clan soldiers are coming to the city, are you willing to fight with me?" Now that the beast tide soldiers are coming to the city, are you willing to fly with the banner of our city? ”

"All of you are united, the city is in the people, the city is destroyed and the people are dead!"
