The horse's hooves of the knight stepped into the air, and even the man and the horse fell into the black and purple swamp, and there was no time to let out an exclamation. The black-purple swamp churned, devouring the knight mercilessly.

No sooner had the steel torrent broken through the ice wall than it crashed headlong into the Death Swamp, a scene like a dumpling that mercilessly devoured the lives of horses and knights.

But this can only be delayed for a while. When the wall is broken, it is like a hole in the embankment that holds back the flow of the river, and it will eventually be washed away by the raging river. Ye Mo has a very clear understanding of this.

Ye Mo looked to the side, and the big pit that Huo Yizhou had photographed - below the pit was the tunnel that the enemy had painstakingly dug.

Ye Mo didn't know how many tunnels there were, and he didn't know how many troops the Hele Empire had put in the tunnels, which planted the seeds of anxiety in his heart, and this anxiety spread as the corroded swamp was gradually filled in, and it became anxious.

"No, I can't put it off any longer, I have to go down and have a look." Ye Mo shook his head vigorously, and then ran towards the pit.

Jumping down the pit, Ye Mo saw the rest of the team, as well as the corpses of the enemies lying crookedly on the ground in the pit, and the air was filled with the smell of blood and burnt.

Needless to say, it should be the handiwork of Li Minjia and Ye Yu, two fire magicians.

However, it seems that everyone in the team has not been harmed, and they all look at ease.

Ye Mo walked forward, squatted down, and looked at a corpse in front of him with nausea.

This corpse was dressed in the robes of a mage of the Hele Imperial Army, and judging by the remaining elemental fluctuations, it should be an earth-type magician. The wound on his body was very simple, he was pierced through the heart by a sword, and he died without much struggle. Judging from the wound, it should be Si Ze's hand,

And most of the surrounding enemy corpses are wounded like this.

Ye Mo untied his robe and took out a piece of parchment from the pocket on the inside of the robe.

Spread it out and look at it, but it was a map of the border city, and near the city wall where Ye Mo was stationed, a few lines were drawn crookedly, extending to the vicinity of the central town guard mansion in the border city.

Ye Mo carefully identified it, determined his location, and then discovered one thing.

That is, less than ten meters away from this tunnel, there is another tunnel. The tunnel seemed to pass directly below the crack in the wall.

Ye Mo thought about it, and had a plan at the moment.

At this time, Yin Lingna also jumped into the pit with Yan Li, and the members of Ye Mo's team were neat.

"Come on, I have an idea. It won't be long out there, I'll cut it short. Ye Mo cleared his throat and said to the team members.

"From here, about ten meters through, there is another tunnel, which leads directly to the town guard's mansion, we will move to that tunnel, and then block the passage, and use the enemy's tunnel to go to the advance retreat circle." Ye Mo said, pointing to the nearby passage wall.

"I'll leave it to Senior Huo Yizhou."

"No problem." Huo Yizhou nodded, didn't talk nonsense, and immediately began to break ground and open the way.

Ye Mo pulled Yin Lingna and beckoned Li Minjia over, and the three of them got together and discussed in a whisper.

As the brains of the team, the decision now determines whether they can escape from the border city smoothly.

"The timing of the enemy's cavalry was too good, and it happened to be the time when the city wall collapsed, and I felt that something was wrong." Yin Lingna said.

"And the two Holy Orders of the enemy ran out of the city so swaggeringly, I think it should be from this tunnel to enter the city, otherwise there is no reason why so many high ranks did not notice." Ye Mo added.

"You mean, the tunnel next door could lead straight to the town guard in the middle of the city? What are they doing digging so far, just go over the walls? Li Minjia asked a question.

"Hmm..."Ye Mo thought for a moment and said, "It should be for concealment." This tunnel is obviously prepared for those two high-level people to enter the city, their first task is obviously to find out the situation in the city, as for the collapse of the city wall, any tunnel can be done, but it just happens that this tunnel has a relatively high degree of completion, and the enemy has already infiltrated it and just made the best use of it. The other tunnels were not long enough, and if the walls were destroyed, the people themselves would be crushed to death. Ye Mo said to the corpse Nunu on the side.

Yin Lingna looked at the end of the tunnel and nodded.

"It's through, come on." At this moment, Huo Yizhou's voice came from the one-person-wide tunnel branch.

Ye Mo and the others immediately stopped talking, and the team members immediately entered the tunnel leading to the town guard mansion in order according to the formation assigned before.

"This—" Si You took a deep breath after entering the tunnel.

The expected battle did not appear, there was not a single enemy in the tunnel, the direction of the city wall behind him had been blocked by the collapsed city wall, and the tunnel in front of him was dark and deep, which made people feel a little embarrassed.

Ye Mo took out his bow and arrows, lowered his voice and said: "Everyone is on alert, the enemy may appear at any time, always be ready for battle, and take your steps lightly." ”

"There will be no enemies behind you, so I'll take the lead." Si Ze, who hadn't spoken much, said and walked to the front of the team and let go of his breath.

The group carefully walked along the tunnel.

"Thankfully, we didn't choose to travel from the ground." Li Minjia lowered her voice and said.

Ye Mo nodded, but did not continue, but thought about something.

If this tunnel really leads directly to the town guard's mansion, then there should already be a large number of low-level warrior magicians from the Hele Empire entering the city. If they retreated from the ground, then Ye Mo and his party would not only have to face the pursuit of the cavalry, but also have to be careful at all times to infiltrate the cultivators who had infiltrated the city through the tunnels.

At this time, Ye Mo's team was actually quite lucky—by mistake, a light came out of the dark.

The enemy would never have imagined that someone would escape along their tunnels.

But the current situation is a little too smooth. Ye Mo and his party walked all the way forward, but they didn't encounter a single Hele Empire at all. Ye Mo calculated according to the speed of travel, and his team had probably traveled a third of the way.

It was so smooth, but it made Ye Mo feel uneasy.

At this moment, the senior brother who was walking in front suddenly stopped.

This sudden move made everyone tighten up and make a posture of vigilance.

At this moment, there was a sudden violent vibration overhead, and sand and gravel continued to fall down the tunnel, and Yan Li opened a thin shield to protect everyone.

"It's... It seems to be cavalry. Yin Lingna said.

"That said... The walls have completely fallen. Ye Mo frowned, the situation was getting more and more serious.

Since the enemy launched the offensive in the early morning, the balance of last night seemed to be as if the Hele Empire had deliberately retained its strength.

"Let's speed up." Si Ze said that he ran forward with an arrow step, without the slightest caution just now.

"We don't have much time left!"
