As a formation base city, Yuanyue City did not consider the defense of the city itself when it was first established.

Its defense standards are not as good as Wang Ji's methods in City No. 92.

At least Wang Gong knew how to arrange several anti-escape formations under the city wall!

But there is no such thing in Yuanyue City.

Due to the confidence in the Fire Dragon Pass, Yuanyue City and other cities in the pass do not have anti-escape formations.

There are some mechanisms, but these mechanisms are not for resisting escape at all, but for extracting the power of the earth's veins.

Zhao Xing and Chen Shijie had prepared the firecracker arrangements yesterday.

The only difficulty is to be careful when escaping.

Because fifth-level firecrackers are really flammable and explosive, and Full Moon City is built on fire veins. If something goes wrong while sneaking, your own people will be in trouble.

"Set off!"

Chen Shijie gave the order.

One hundred magic evasion magicians and Sinong all headed towards Yuanyue City with a large number of firecrackers.

"Divine protection!"

Zhao Xing stretched out his hand and a large firecracker was enveloped in golden light and sank into the ground.

Then he shuttled underground carrying firecrackers.

Yuanyue City is as big as 25 football fields.

But there aren't actually that many parts to fry.

It is enough for the city lord's palace in Basda and the four judicial formations of Yuanyue City to be blown up.

The most important of them is the city lord's palace in Batha.

Because this is the core of Yuanyue City.

The formations distributed at the four corners of Yuan Yue City were blown up. These four nodes were destroyed. The defense formations in the southern section of Yuan Yue City and Huolong Pass were only cut off and could still be repaired.

But if the City Lord's Mansion is blown up, it will have to be completely rebuilt. As Pang Guangyao said, it will take three or four months to rebuild it.

This part can only be done by Chen Shijie and Zhao Xing.

Why?

Because no one else can fully utilize the power of firecrackers, and the magic circle under the city lord's mansion is relatively complicated.

When a hundred people were sneaking underground to the outside of the city, Chen Shijie sent an order to everyone through the earth's veins.

"The four groups of personnel retreated in unison after half an hour, and detonated five quarters of an hour later!"

"After half an hour, no matter whether the arrangements are in place or not, we have to retreat! Do you understand?"

"clear!"

Chen Shijie said: "The action starts from now on!"

Buzz~

After that, a hundred people dispersed in multiple directions at the bottom of the city.

Zhao Xing and Chen Shijie continued to sneak towards the city lord's mansion in the center.

They carry the largest amount.

The road to go through is also more complicated.

As the core of the formation, the City Lord's Mansion is pressed against the fire veins, and it is really difficult to sneak through it if it is weak.

Two quarters of an hour later, Chen Shijie and Zhao Xing stopped.

"We're here, ahead is the Fiery Dragon Formation."

In the earth vein in front, there is a dragon-shaped flame beating. The dragon's head is huge, its mouth is opened, and it is facing downwards.

Countless amounts of earth fire power were drawn into the dragon's head, and then transformed through the magic circle and transported to the small fortresses around Yuanyue City.

The small fortresses around Yuanyue City are equivalent to formation base transfer stations.

Finally, they gathered at Huolongguan City.

The Guancheng section is the most vulnerable part of the Flame Mountain Range, but after many complex formations have been superimposed, it has become the strongest pass.

"Split up, I'll start from the earthquake position, you start from... uh, I'll start from the southeast, you start from the southwest." Zhao Xing was halfway through, and then he remembered that Lao Chen didn't know the knowledge about Gongjia's magic circle.

He immediately changed his tune.

"Don't look down on people." Chen Shijie said, "Since I came back last time, I have been supplementing my basic knowledge of magic circles."

"The separation position is fire, and the exchange position is water. You asked me to start the layout from the southwest. Isn't the principle that the separation and exchange positions can maximize the power of the firecrackers?"

"When you set off firecrackers from the seismic position, don't you just want to use the power of the firecrackers to destroy the outlet of the Fire Dragon Formation, causing the ground fire to condense and eventually self-destruct?"

"Awesome!" Zhao Xing gave a thumbs up.

"What's so great? Who doesn't know how to learn? It's just a trivial matter." Chen Shijie said calmly: "While you were farming in Dongsang City, I was not idle either."

Although he said this, looking at Zhao Xing's stunned expression, Chen Shijie felt secretly happy.

I read at night for more than half a month, and finally I was quietly amazed by this guy. My efforts were not in vain!

Now that Lao Chen knows it, it will be more convenient.

Zhao Xing carefully rolled up the firecrackers and controlled the Octagonal Underground Palace to approach.

He and Chen Shijie each brought one hundred fifth-grade firecrackers, a total of one thousand four hundred firecrackers.

The power of fifth-level firecrackers is calculated based on each section.

The power of a single fifth-level top-grade firecracker is enough to penetrate the defense of a fifth-level armor.

If we were to blow up the city lord's palace in other places, just relying on these 1,400 firecrackers would not be enough.

Because the location they are currently sneaking into is relatively deep, two hundred meters below.

Moreover, the foundation of the City Lord's Mansion is so solid that it is simply not enough to blow it up.

But this is the Full Moon City, itself built on a powder keg.

The fifth-level firecracker only needs to light this powder keg.

A quarter of an hour later, Zhao Xing summoned him and asked:

"Done?"

"It's still a little bit close." Chen Shijie was not so quick, "Please check it for me and see if there are any errors or omissions."

"Okay." Zhao Xing finished his work and immediately came to review the firecrackers placed by Chen Shijie.

Another quarter of an hour passed, and the agreed retreat time was approaching. Zhao Xing and Chen Shijie cross-checked twice.

After confirming that there was no problem, we immediately began to retreat.

After the two left, only firecrackers were left buried underground, wrapped in golden light.

Action personnel know how to do this.

Because this is not a spell at all, it just attaches vitality to the firecrackers and wraps them.

As long as it reaches the eighth level, its ability to control vitality can do this, and it will automatically dissipate after three quarters of an hour.

Without the vitality package, the firecrackers will soon explode in the hot underground.

A quarter of an hour later, Zhao Xing and Chen Shijie took the lead in arriving underground outside the city.

The remaining personnel returned to their positions one after another.

Another quarter of an hour later, one hundred operatives were completely present, and no one had any accidents.

"withdraw!"

Chen Shijie immediately gave the order.

It would detonate in only a quarter of an hour, and they had to stay away, otherwise they would be affected.

In the city lord's mansion, Batha woke up from her dream.

The two beauties from the Fire Demon Clan next to him also woke up.

"What's the matter, sir?"

Basda covered her head and said, "I had a nightmare just now. I dreamed that I was dead."

Tiangang Disha's physical training, Basda, a sixth-grade warrior, has seven souls that are already very powerful.

The seven souls feed back the soul of life, and the soul of life can often interact with the soul of heaven and the soul of earth, and can get some precognitive responses.

These reactions are generally related to 'rebirth' and 'karma'.

Therefore, the more advanced warriors are, the harder it is for them to be attacked by surprise, because their vigilance will be very high.

"How could it be possible? We are in the Fire Dragon Pass..."
