On the one hand, it can reduce the forces of the four Nation Alliance, on the other hand, it can preserve their combat effectiveness.

In order to really eliminate Shen Yanxiao's influence, the alliance of four countries must seize the sun, which is located in the center of fifty cities. Even if the alliance of four countries wants to break through a direct road to the sun, it also needs to fight with seven or eight cities in this process.

This is Shen Yanxiao's best chance.

"During this period of time, Nazhi and Xiaowei strengthened the FA array outside each city, especially around the sun, which must be full of FA arrays. Ah Yu and Yang Xi prepared materials and weapons together. We must make sure that the fire power of our artillery cannot be cut off after the war. Qixia, you and Durang together persuade the human beings in each city to mix into the five main cities. I'll let fautu prepare for the demons. " Shen Yanxiao gave the order decisively. This was her first time to participate in a large-scale battle. In this war, she could not lose! I can't afford to lose.

"When will Xiao Feng come back?" Shen Yanxiao thought of the blue sealed glass that had not come back.

"I'm not sure. The news has been sent, but I haven't heard back. I hope he can come back before the war." Qi Xia sighed. The battle effectiveness of blue seal glass is the most powerful one among them. If there is blue seal glass, they will be more confident.

But blue sealing glass didn't get any news back in this period, which made them worried.

After all, there are two phoenix beside the blue seal glass. Their three combat effectiveness is very important for the barren land now.

"Then you should deal with these matters first, and ask me if you have anything." Shen Yanxiao can only wait patiently.

Knowing their respective tasks, the five animals did not delay at once to carry out.

They are racing against time!

In the next ten days, more than 50 cities under the influence of Shen Yanxiao took action.

All the merchants and residents in the city were moved to four main cities except the sun.

Because of Durang's previous control over the people, the number of people in each city is not large. Otherwise, the four main cities will not be able to hold 50 people.

Before, the main city of the barren land was deliberately vacant. The original city had no human beings but demons. Now even if there were people entering, it would not be too crowded.

Soon there was no human habitation in any city other than the five main cities, and the defense of all the cities was handed over to the demons.

The dungeons of demons are connected with each other. They can evacuate from the underground faster. When they have to leave, they will block the entrance of the dungeons and prevent anyone from entering.

Yang Xi began to speed up the building of artillery shells. Ye Qing and Yin jiuchen led a group of pharmacists to make potions day and night. Donald Zhi and Li Xiaowei had already taken the people sent by Xuanwu aristocratic family to make a killing array around the sun.

The whole barren land is like a huge machine, which runs under the command of Shen Yanxiao.

The time of thirteen days is so short that it will pass through your fingers if you are not careful.

Day by day, the armies of the four countries have been attacking from their own countries, crossing a long distance and converging at the entrance of the eastern part of the barren land.
