Cloud Piercing Spire unlocks the T3 Tech Defense Building: Plasma Cutter! It is a deadly single lethal tower, with the Dual Plasma Launcher firing two high-energy rays of plasma that continuously cut all units in half of their survivable armor. Despite not having the same group attack capabilities as regular towers, his high single-target damage and range that is only slightly lower than that of a cannon is a nightmare for all Flesh Shield units, especially when it comes to the Burst Trench that can be obtained by expanding technology with the addition of Cloud Piercing Spire.

It can be seen that the ability of the foehn wind in terms of defense is extremely strong, Yi Xiaofan was quite interested and wanted to look down, but a world announcement interrupted his train of thought.

"Ding! World Bulletin: In retaliation for the commanders for occupying the cities in the war zone, the Yuri Empire is planning to send a large number of elite troops to regain control of the city, this time the threat we face is unprecedented, commanders hurry up and prepare for battle, the storm is coming! ”

"Ding! System Announcement: The elite troops of the Yuri Empire are about to launch an attack on your city in twenty-four hours, and the number of troops is one hundred times the total number of players within ten kilometers of the current city. For each infantry or unit killed, an individual will earn 1 merit point and earn 1 point. Merit points can be exchanged for valuable items in the Merit Shop, and points can be exchanged for rare class technology after the event ends. ”

"There's another big event ......"

Yi Xiaofan took a closer look at the content of this event, although the number of system troops in this siege is only a hundred times the number of players, and 99% of the players are now the upper limit of 200 points or more, and the number of troops will basically not suffer. But this time, Yuri dispatched all second-level elite troops, which is a bit difficult. Even if all players are willing to spend money to buy elite card explosive troops, but you can't burst out so many second-level troops for a while, the most important thing is that Yuri is likely to send high-level troops to join the battle, in the current situation where players are generally single, it can be said that the winner is indistinguishable.

As soon as the world announcement ended, Excellence pulled him into the voice group.

"What to do Xiaofan, there are as many as 70,000 people in our three cities, plus unrelated players within ten kilometers of the surrounding area, the number must be more than 100,000, and each city has to face at least two or three million second-level elite troops, this is simply terrifying."

"That's right! In addition, we have just fought with the Wolf Tooth Alliance and the Dragon Alliance, and it has only been a day or two, and there is no time to replenish the troops. Yue Zifan said a very serious problem.

Night Wuxiu sent a statistical chart to Yi Xiaofan, and said: "This is the statistical data of the two cities that arranged for Qiao Ward and Cup Moting to be stationed in 96 and 85 before. At present, the strength of these two cities is about 2 million, and the infantry strength accounts for 40 percent, and the gap between the number of Yuri's elite troops is about 1 million. And City 25 now has only more than 300,000 troops, and it is all infantry units......"

After listening to the report, Yi Xiaofan was indeed a very bad thing, which reminded him of the Wolf Tooth Alliance, and it seemed that after helping them "get free", it allowed them to avoid the bloodbath of this system.

"Don't be so pessimistic, in my opinion, our defense is actually not too weak." Yi Xiaofan stood on the edge of the Foehn Chariot Factory, looked at the sea in the distance, and continued: "First of all! Looking at the major war zones, are there any fifth-level cities now? Two days ago, the three or four million troops of the Wolf Tooth Alliance failed to defeat us, so the AI in the system can destroy us? Unless you admit that your head is not as good as the system AI! ”

Yi Xiaofan paused for a moment and said: "The investment I received before is still coming in, I will reduce 96 and 85 as quickly as possible and upgrade the two cities to level five, and do my best to improve the city's defense capabilities." In addition, in the past two days, if you have an acceleration card, use the acceleration card, and if you don't have it, don't force it, try to build defense towers and meat shield troops that can be carried. And everyone knows that my class has a great advantage in battle, so I will spread my forces to protect the three cities. Of course, the most important point is that there is a high probability that the troops sent by Yuri this time will appear in high-level troops, which is the biggest threat to the city's defense. ”

After listening to Yi Xiaofan's words, Zhuo Zhuo sighed and said: "In the end, we are still not fat enough, and the resources are not enough, if it is the same as those old guilds, it will be cool!" ”

"Don't worry! After a while, you'll have a headache for not having more mining carts to mine and more buildings to build refineries! Yi Xiaofan said with a smile.

"What, you have good news again?"

"I can't tell you yet!"

After discussing the specific defensive details with everyone, Yi Xiaofan began to prepare. He kept refreshing Yunru and devouring Yunru in the United Fortress, and at the same time used the remaining 20,000 troops to start exploring the west and north and south along the United Fortress that he had occupied.

It took about a dozen hours for Yi Xiaofan to find three joint fortresses, and he forcibly used siege mechs with Boris, Yunru, and virus snipers to push down all the buildings in the fortress at any cost, and occupied the Yuri base car above.

Using those base cars, Yi Xiaofan, who had a building ceiling of two hundred and fifty, built a large number of ore refineries on the spot to collect the inventory ores in the super mine, and after almost twenty hours, Yi Xiaofan already had more than five billion in his hands. He exchanged all the remaining diamonds in his hands at a low price of 60,000 yuan into more than 2 billion funds, so that he could barely raise enough money for the two cities to be promoted to the fifth level.

Yi Xiaofan teleported to the two cities of 96 and 85 respectively, and in the cheers of the players of the Extraordinary Alliance, the city reached level five in seconds.

700 million to confess, Yi Xiaofan gained a full 70,000 merit points, and then everyone reading the book here can think of what he wants to do with their toes!

"Expand!"

How can 20,000 troops defend three cities at the same time be enough? Opening the meritorious mall, Yi Xiaofan slammed according to the first-level military expansion order without blinking. As soon as the 35 first-level military expansion order was used, the upper limit of 1,750 troops was expanded tenfold to 17,500 under the influence of the bug, and the total strength exceeded 40,000 in an instant.

After completing the pre-war preparations, Yi Xiaofan began to study the detailed defense methods, first of all, the unrestricted control building static grid that had just arrived, the psychedelic grid must be spread out outside the twelve passages into the city in the three cities, and Sheng Long's EMD mine, this thing made Long Teng Lingyun suffer enough last time.
