The burning battlefield is illuminated by the moonlight, and the broken city walls are filled with smoke.

The power of the spell faded and appeared, and the flames spread crazily across the earth.

As the scorching flames rose, corpses lying on the ground were reflected, the bright red flowing on the ground was reflected, and ferocious and angry faces were also reflected.

The fierce collision of sword blades, the curses and wails at close range, the bodies wrestling together, and the roar of the magic cannon were like four movements, forming a symphony filled with steel and death.

When the front team falls, the back team rises up.

Scenes like this fill every corner of the battlefield, with one side fighting for imprisonment and the other fighting for freedom.

Upstairs at the city gate where people looked longingly, Lei Xiao felt the trembling coming from the earth while looking at the fierce battle scenes filled with blood around him, and his uneasiness became more obvious.

Just like what Orr introduced.

Compared with the beginning, although the opponent's offensive was gradually increasing, many elite troops were successively invested in launching a fierce and comprehensive offensive against the five-kilometer-long Wangxing City Wall.

However, our defenders were not at a disadvantage due to their advantages in equipment and potions, as well as the fact that Erza and Xiaohuan, who had been transforming into themselves and Ariel, wandering around to boost morale, and the calm command of the commanders.

.

However, although the enemy and we are evenly matched and our losses are significantly less than the other's, Lei Xiao clearly understands.

The real deadly storm is coming soon.

Once the strong wind rises, it is the moment that determines life and death.

"The key problem is that I don't know which areas are going to have storms."

Lei Xiao frowned and began to think to himself.

"If I can detect some clues, I can at least take some precautions, which is much better than being caught off guard and being kicked by the enemy."

"The area of ​​Hope Star City, Luolong City, Mountain Fortress, Territory, and even Kongqing Town is too vast. It is undoubtedly too difficult to judge how the other party will find another way."

Thinking of this, Lei Xiao's brows began to frown even more.

I have to say that compared to passive defense, I still prefer active offense.

"Lord, have you noticed anything strange?"

I saw Chao Yan coming up with small steps, blinking his big eyes and saying: "Facing a huge number of heavily armored enemies, they are rushing towards the city wall one after another. It is not uncommon to cause the earth to tremble, but the frequency of this kind of trembling.

It should be relatively chaotic..."

"You're right."

After hearing Chaoyan's words, Lei Xiao brought his thoughts back to reality, began to concentrate, and carefully felt the vibrations coming from the soles of his feet.

On a fierce and unusual battlefield, although this kind of tremor is not obvious, for Lei Xiao, whose senses are already different from ordinary people, he can still feel it easily.

"Chaoyan, you mean, are there other places where the tremors are relatively stable?"

Lei Xiao reacted quickly and asked immediately.

Before this, because Lei Xiao had been focusing all his attention on thinking about the other party's next move, he did not pay attention to such minutiae.

"Yes, Lord."

Chaoyan held up the witch hat on his head, nodded and said: "When I was teleported here just now, the tremors I felt in the City Lord's Mansion were completely different from those here, and they were relatively regular."

At this point, Chaoyan tilted his head and curled his lips and said, "Is it because of the long distance that the earth trembles regularly?"

"Impossible. The distance from the city gate to the city lord's palace is only a few kilometers, so it will never have such a big impact."

Teresa, who had been listening carefully, frowned and said: "If this is really the case, there is only one possibility, unless it is..."

"Unless there are two sources of tremors, the tremors Chaoyan felt in the City Lord's Mansion did not come from here."

Lei Xiao took over the conversation and said solemnly: "We will go back to the city lord's mansion to confirm now!"

After finishing speaking, under Jiang Li's transmission, the group quickly returned to the meeting hall on the first floor of the City Lord's Mansion.

"Lord, this place is indeed completely different from the city wall!"

Huzhang pressed his ears to the ground for a moment and reported to Lei Xiao: "Although the battle ahead has covered up most of the traces, my subordinates can still feel that this regular and unknown tremor seems to come from the ground!

"

"In addition, judging from the increasingly intense sound, the source of this regular tremor is still some distance away from Wangxing City, but it is no longer far away."

Knotweed's voice became more solemn and he added another sentence.

"Is that true? It seems we don't have much time left."

Lei Xiao rubbed his chin and nodded thoughtfully: "At this juncture, this kind of tremor is definitely not groundless. I think I know how the other party will find another way next time."

"Lord, are you saying that the other party is digging a hole underground in an attempt to cross the city wall and enter the city directly?"

Ariel immediately understood what Lei Xiao meant, blinked her starry eyes and said in disbelief: "This is too crazy!"

"That's the only reasonable explanation."

Lei Xiao first touched Chao Yan's head as a sign of praise, and then said firmly: "In this way, the whereabouts of the opponent's two missing legions are very obvious, they are underground!"

"So, when the other party was last supplying supplies in Lute City, they had divided their troops into two groups. One group was marching normally on the ground, while the other group was marching underground?"

Jiang Li blinked her long eyelashes and continued thinking along with Lei Xiao's train of thought: "The large troops marching on the ground are so powerful that they can also serve as cover, making it difficult for the two legions marching underground to be detected.

The same is true in siege, the opponent is using trembling to cover up the trembling!"

"Senior Jiang Li is right. When our attention is completely focused on the city wall, if these two legions suddenly appear in the city, and cooperate with the support of the main strong men, such internal and external cooperation will be enough to tip the balance of victory.

Let us get into trouble."

Ariel frowned and muttered: "It's really a clever and sinister plan."

"Yes, I have always focused my thinking on the entire area before, thinking that the other party would still cause trouble in other areas. I didn't expect that the other party would directly choose a new path this time to look out for Star City itself."

Lei Xiao nodded and slowly took a deep breath: "Once the other party's plan succeeds, the consequences will be disastrous."

"But Lord, my subordinates still have something unclear."

Bai Wei, who had just been promoted to the fourth level, gently waved her fluffy snow-white tail and said in confusion: "Lute City is so far away from here. Even if the opponent digs holes and marches, they can't dig so fast. Besides, it's not possible for them to dig holes so fast."

Let the two legions advance together."

"This little sister from the Snow Wolf clan, actually this is not a difficult task."

Teresa looked up and down at Bai Wei's pair of erect ears and big tail. She was obviously very interested in this fluffy thing and began to explain.

"As long as there is a fifth-level earth magician who is good at digging, and a number of fourth-level earth magicians leading the team, it is not impossible to forcibly open a path underground."

Speaking of this, Teresa's expression became solemn again: "In addition, there are several extremely difficult and powerful monsters that can also do this. To a certain extent, these things can

Much more difficult to deal with than ordinary strong men."

"So we must be prepared for the worst."

Lei Xiao took over the conversation and ordered Jiang Li to teleport as quickly as possible to bring back Orr who was commanding on the front line.

"See your lord!"

Not long after, Orr, covered in blood, appeared in front of Lei Xiao.

Of course, although the face of this middle-aged subordinate was darkened by gunpowder smoke, as a flexible wind magician, the blood did not come from him.

"Al, this is the situation."

Lei Xiao did not hesitate and explained the analysis just now.

"Lord, are you saying that the enemy will attack the city directly from underground?"

After listening to Lei Xiao's concise introduction, Orr looked shocked and swallowed involuntarily.

It is conceivable that since the opponent chose this strategy of surprise troops, the two legions dormant underground must be carefully selected elite troops.

In Wangxing City, although the residents have already been properly placed in the rear, they will not be affected.

However, the remaining forces on our side are only 5 new recruits who have never been on the battlefield, and the other 5 have already gone to the city wall to provide support.

In this case, not to mention two enemy elite legions, even just one can easily defeat our recruit legions scattered throughout the city for defense.

Once there are swords and soldiers everywhere in the city, the morale of the city wall that is attacked from both sides will be greatly affected, and the result is self-evident.

Thinking of this, Al, as the commander-in-chief of Wangxing City, was sweating profusely and kept wiping the sweat beads off his forehead.

"Fortunately, we have seen through each other's tricks in time."

Lei Xiao first asked Bai Wei to give Orr a cup of warm tea to signal him to calm down, and then asked: "How many open areas are there in the city?"

"Back to Lord, there are two places."

Al drank the tea in one gulp and immediately understood what Lei Xiao meant.

Since the enemy chooses to invade the city, they will definitely not disperse their troops, otherwise they will be easily defeated one by one by our side.

Under this premise, only open areas in the city can facilitate the opponent's rapid assembly and maximize their combat power.

In other words, the opponent's location for breaking out of the ground will definitely be in an open area in the city.

"Lord, these two locations are the central square in front of the city lord's palace and the airport storage area in the south of the city."

Orr held the tea cup and said to Lei Xiao: "Especially the storage area in the south of the city, which is not far from the city wall and is weakly defended. It is a good place to break out of the ground, and the central square is only a few feet away from the city lord's palace.
