There are three types of war barriers. The first is the primary war barrier, which can only provide ordinary peripheral protection to the garrison or city to defend against the damage caused by artillery and divine thunders such as artillery and divine thunder. However, it has no effect on cold weapons such as bows and arrows. Of course, defense has a certain limit. Once the power generated by the artillery and divine thunder explosion exceeds this limit, the war barrier will lose its effectiveness. The blood volume of the primary war barrier is 100 million, and only if the cumulative explosion equivalent exceeds 100 million, the primary war barrier will break and disappear.

To build a primary war barrier, you need to complete a large mythical mission of one hundred people. After completing this mission, you can build a primary war barrier at your own station or city, with a cost of five million gold coins.

The second type is the advanced war barrier, which can provide ordinary peripheral protection to the garrison and cities, and can also provide internal protection to the garrison and the main buildings of the city. This kind of war barrier can not only protect enemies from outside the city, but also protect enemies lurking in the city from causing great damage to the main buildings of the city. The health of the advanced war barrier is one billion. To obtain the advanced war barrier, you need to complete a large magic-level mission of 500 people before upgrading the primary war barrier in the garrison or city into an advanced war barrier. The upgrade price is 20 million gold coins.

The third type is the ultimate war barrier, which can provide ordinary peripheral protection to the garrison and city, and provide internal protection to all buildings in the garrison and city. The health of the ultimate war barrier is 10 billion. To obtain the ultimate war barrier, a team of two thousand people requires a large elite-level task to upgrade the advanced war barrier in the garrison or city into the ultimate war barrier, and the upgrade price is 300 million gold coins.

Based on the information obtained from Instructor Mo and combined with his own observations, Xiao Han concluded that the war barrier in Edo Castle is an advanced war barrier. However, the advanced war barrier is also subdivided. According to the number of buildings that can be protected, it can be divided into five levels. The highest-level high-war barrier can protect the three hundred buildings in the war barrier. When the war barrier is not opened, Xiao Han has no idea which buildings they focused on protecting. The only way to solve the problem is to blow up the tower where the war barrier is located first.

Of course, the launch tower of the war barrier is not completely undefensive, and it is not that simple to destroy it. The launch tower of the advanced war barrier is 100 million. If used to calculate it, it is equivalent to the equivalent of the explosion of fifty nine-sky sky thunders or two hundred sky fire god thunders.

If all the divine thunders were used to blow up the barrier launch tower, what should we do if the remaining turrets and arrow towers were left? We wouldn't be instructing the monsters under our command to go up and destroy them bit by bit.

Xiao Han calculated that he had thirty-seven Nine Sky Thunders, and Xiaodie and Wu Ling had 66 Heavenly Fire God Thunders. Xiao Han had to make good use of these resources at hand. Only by using these limited resources to maximize their value can the task be completed smoothly.

Instructor Mo and Lin Tianlong had no way to rent a restaurant in the city, so they could only find a secluded place outside the city to study the war barrier. Lin Tianlong enjoyed this kind of two-person world. Looking at Instructor Mo's beautiful face, he couldn't help but feel excited.

"You're going to die, sit up honestly." Instructor Mo patted Lin Tianlong's hand and threw a stack of information in front of Lin Tianlong. "Study it carefully for me, and I won't be allowed to eat tomorrow if I don't study it."

Lin Tianlong immediately showed a bitter face, but had no choice but to read the information obediently.

Lin Tianlong was silent for a moment, and suddenly asked worriedly: "Xiaoxue, will the organization agree to the matter between us?"

"I've already said it." Instructor Mo looked down at the information in his hand and said casually.

"Hmm?" Lin Tianlong didn't understand for a moment.

"I have reported to the organization and the organization agreed." Instructor Mo's cheeks were slightly red.

Lin Tianlong held Instructor Mo's jade hand and was moved. It turned out that she thought much more carefully than herself. She had not expected these things before, but she asked her to do them at a girl's house. Lin Tianlong couldn't help but feel a little guilty.

Instructor Mo was also a little reluctant to see Lin Tianlong's guilty expression and glanced at Lin Tianlong: "Remember to be kind to me in the future, otherwise, hum," Instructor Mo raised his fist.

Lin Tianlong immediately straightened his back: "Wife, obey the order."

After studying the data for a while, everyone realized the seriousness of the matter. The war barriers in the three main cities are all advanced, which means they have to spend a lot of energy to destroy the war barrier first. Otherwise, the mission may fail, but destroying the war barrier will consume a lot of divine thunder. If the divine thunder consumes too much, everyone will not be able to complete the next task.

"Tsk tsk, the military headquarters is really willing to spend money. A high-level war barrier costs 25 million gold coins, and three are 75 million. If it is exchanged for RMB, it will be 750 million. This 750 million falls into the pockets of senior executives of the Tianxia Company again." Zhang Mo sighed.

750 million yuan has become a few virtual items. They are really willing to do so. If this money is used to develop the economy, they don’t know how much profit it can create. Of course, the military headquarters also has its own plans. It is much more cost-effective to defend the three main cities first than to wait until the national war is severely damaged and then rebuilt. Moreover, after the main city is defended, they can let go of other countries and maybe make more money.

They think this way, it is not bad for other countries? After the Japanese side starts, more countries will definitely upgrade their main city to fortresses. Who can get the advantage at that time? Anyway, players are above level 50, and they will not lose the level even if they are hung up. Just let it go. Destroy an enemy building and a village can get some money from the server, but compared to the money spent on building these buildings, it is just a drop in the bucket. Of course, occupying cities from other countries is a different matter. The benefits obtained from occupying a city are quite huge, including taxes, buying and selling goods, etc., which is equivalent to disguised economic plundering of other countries, and the economic benefits generated are quite huge. I believe that the Japanese military headquarters are just the idea of ​​making the main cities of other countries, otherwise they would not have spent so much money to build their own main city.

"I have a way, but I don't know if it's feasible." Xiao Han said.

"Oh, let's talk?"

"A formation is set up with divine thunder outside the war barrier launch tower to strengthen the power of divine thunder. But I don't know if it is effective. How many divine thunders can make it work?" Xiao Han said.

When Instructor Mo heard Xiao Han's words, he started to calculate the equivalent of each divine thunder explosion, and how much effect the effect will be generated after being arranged into a formation, and how far the divine thunder should be placed at the distance from the war barrier launch tower. The calculation amount is quite huge. Instructor Mo's eyebrows were deeply locked, which made Lin Tianlong feel a little distressed, and Lin Tianlong also began to help calculate.

Although Xiao Han knew how to set up the formation, he did not know much about the relevant data of the formations drawn by Instructor Mo. These data were very troublesome to explain, and they may not be able to be used in normal times, so Instructor Mo did not explain in detail to Xiao Han. So Xiao Han couldn't help much now.

After a long time, Instructor Mo calculated the relevant data. "If it is enough to arrange forty-nine within a radius of fifty meters, it is enough. If it is within a radius of ten meters, only thirty-six divine thunders are needed. However, our number of divine thunders is not large, so we must arrange thirty-six thunder arrays, that is, we must arrange thunder arrays within a radius of ten meters of war barriers. Although there are no special people around the war barrier launch tower, if we stay around the war barrier launch tower for too long, it will easily arouse others' suspicion. Therefore, this task is difficult." Instructor Mo said worriedly, "The detonation process is also quite troublesome. If people get too close, they may be killed directly by the power generated by the explosion. Because the power generated by the explosion of thirty-six divine thunders is quite huge. If we do not stand a hundred meters away, we may encounter danger."

"There is a way to detonate the process. If it really doesn't work, we can sacrifice the pets in our hands." Xiao Han said. Of course, Xiao Han would not let the Fire Kirin, the Golden-winged Roc, the Zhu Yan Beast and the Nether Bone Dragon King sacrifice. The puppet stone demon and the level 100 bone dragon that he just caught can still be used.

"Then there is only the arrangement process. Due to the different situations and terrain in various places, we will find ways to discuss them in a unified manner at that time." Instructor Mo said.

Everyone agreed.

"In one day, understand the situation around the barrier launch tower and then come up with a solution to the problem." Instructor Mo said.

Xiao Han looked at the tall tower standing in the center of the city from the restaurant window, and was already thinking about it. I believe that he would come up with a solution soon.

Xiao Han smiled at Xiaodie and Wu Ling: "Today I want to observe the terrain around the tower so that I can come up with a plan."

Xiaodie asked softly, "Do you want the two of us to accompany you?"

"No need. If there are too many people, or staying around the war barrier launch tower for too long, it will easily arouse others' suspicion. I am going to use invisibility to observe the terrain over there." Xiao Han explained.

If Xiao Han used invisibility to observe the terrain, it would be a bit cumbersome for them to follow. Xiaodie replied: "Okay, be careful."

Xiao Han smiled slightly, looked at Wu Ling, and then looked at Xiaodie: "You can walk around. There should be no big problems when wearing masks, not to mention that Wu Ling can speak Japanese."

Xiaodie and Wu Ling looked at each other and said, "We can just stay in the restaurant."
