The battle on the second day of the Avalon Fortress offensive and defensive battle, like the first day, ended in the seesaw of the two armies.

　　 The results of the Hiran Army have not made any substantial progress.

　　 On the third day, the mounds of the Hiran Army were finally piled up, and the tunnel was finally dug.

　　 After learning that both the mound and the tunnel can be put into battle, Dominic immediately ordered the use of the mound and tunnel.

　　 Regarding the authenticity of the Hiran Army, the Michael Knights have already taken precautions.

　　 The Michael Knights have already placed a bowl of water on the ground near the outer wall at intervals.

　　 Several soldiers were set up near each bowl of water to observe the bowl of water in shifts.

　　 If the bowl of water has a face, it means there is vibration underground.

　　This can quickly determine the location of the enemy tunnel and quickly intercept it.

　　 If the foundation of the hostile city is available for excavation, you can dig tunnels to attack. This is also a common tactic in siege warfare in this era.

　　The siege party that uses tunnel warfare will dig one or more tunnels, and continue to use wood to support the ground as it advances.

　　 Destroy the walls of the city by digging tunnels, or pass under the foundation of the walls, and open an entrance in the city so that troops outside the city can sneak into the city.

　　 Although tunnel warfare is a common method in siege, there are also countermeasures against it, and with continuous improvement, tunnel warfare countermeasures are still very developed.

　　 At the beginning of the offensive and defensive war, Su Cheng transferred 3,000 soldiers to Deng Jiaer, and handed over to Deng Jiaer the authentic task of countering the Hiran Army.

　　 After the soldiers in charge of observing the water bowl found ripples in the water, these soldiers immediately notified the news to Deng Jiaer, who was in charge of dealing with the tunnels of the Hiran Army.

　　 Deng Jiaer quickly judged the general location of the tunnels of the Xilan Army based on the different size of the ripples of the various water bowls.

　　 After judging the general location of the tunnels through the water bowl, Deng Jiaer led her soldiers to quickly launch a countermeasure, blocking the tunnels of the Hiran Army.

There is a deep trench dug at the foot of the outer wall of the Avalon Fortress. This trench is specially used to deal with the enemy tunnel. As long as the tunnel of the Hiran Army is found, it will be sprinkled with various combustible straws, etc. Throwing objects into the tunnel, using fire and smoke to force the Hiran army back.

　　 There were screams in the tunnel for a while, and the smell of burnt skin spread from the tunnel.

Compared with siege towers, crash vehicles and other siege equipment, it is really easy to deal with tunnels. As long as the general position of the enemy tunnel can be identified, the trenches are dug deep enough, and more flammable materials that can be used for gas and smoke are prepared. Even if an army of one million came, they could still be stuck in the tunnel and couldn't climb out.

　　 Many soldiers of the Hiran Army couldn't retreat in the tunnel, choked by the dense smoke, and then couldn't get up again.

　　 The Hiran Army soldiers, who were not choked to death by the heavy smoke, began to retreat hurriedly.

When 　　 hurriedly retreated, it triggered a stampede on himself, causing many casualties.

　　 "Retreat! Give up the authenticity!"

　　The Hiran army general who was in charge of the tunnel warfare, saw that the Michael Knights had been prepared for their tunnel, and he could only sigh in desperation, and ordered the retreat and abandon the tunnel.

　　 Compared to the tunnels, the dozens of mounds built by the Hiran Army played a lot of role.

　　 It took more than two days to mobilize tens of thousands of soldiers, and finally succeeded in building dozens of high mounds under the outer walls of the Avalon Fortress.

　　 These dozens of high mounds are 2 meters higher than the inner wall of the Avalon Fortress on the opposite side.

　　 On each mound, there are also bunkers to defend the bowmen.

　　Each mound can accommodate about forty crossbowmen standing on it, shooting down the outer wall of the Avalon Fortress, and covering the comrades who are attacking the city under their feet.

　　 The Hiran archer and crossbowmen standing on the mound threw arrows like torrential rain toward the outer wall of the Avalon fortress.

　　 The sound of shooting through the armor and flesh of the soldiers of the Michael Knights, and the screams of the soldiers of the Michael Knights one after another.

　　 Because the group of Hiran Army's crossbowmen standing on the mound was condescending, the battlements of the outer city wall lost their role as a shelter.

　　 This caused considerable casualties to the defenders on the outer wall.

　　 The commanders of each section of the city wall immediately ordered the crossbowmen on their side to fight back, raising their heads and shooting.

　　 It’s just that because there are bunkers on each mound, the counterbowmen of the Michael Knights are not very effective.

　　 With the participation of these mounds, the battle on the wall became more intense and bloody.

　　嗖!

　　 A flowing arrow fell from the sky and hit Darlene's shoulder armor.

　　 "Hmm..."

　　 Darlena snorted painfully, then raised her hand and pulled out the arrow that hit her left shoulder armor.

　　 Fortunately, the arrow only hit her armor. Under the protection of the armor, the arrow only scratched her skin and flesh, and did not cause her to suffer too much damage.

　　 "Really...what are the crossbowmen on the inner wall doing..."

　　 Darina bitterly threw the arrow that hit her to the ground, and complained very dissatisfied.

　　 "Hurry up and shoot all the enemy soldiers on the mound."

　　 These dozens of high mounds brought a lot of trouble to the defenders of the outer city wall.

　　 The Hiran Army crossbowmen standing on these dozens of mounds, because they were shooting down, the defenders on the outer city wall lost the protection of the battlements and were shot miserably.

　　Dalina and the others had to raise their shields to guard against the enemy infantry in front of them, and at the same time guard against the dense rain of arrows that fell from their heads from time to time.

　　 Seeing that the crossbowmen staying on the safe inner city wall were unable to solve the enemy soldiers on the mound~lightnovelpub.net~ Darlene couldn't help but get annoyed and cursed their inaction.

　　 But Darlena misunderstood the crossbowmen on the inner wall this time.

　　 After the Hiran Army's crossbowmen climbed up the mounds, the comrades on the inner city wall immediately began to counterattack.

　　 It's just that these mounds are higher than the inner city wall, and there are bunkers for protection, because the counterattack effect of the inner city wall is not ideal.

At the moment when Darlene pulled out the arrow on her shoulder, and at the moment when she was distracted, a soldier of the Hiran Army not far away from her looked at the timing and raised the battle axe in his hand high to reach Darlene. Na pounced.

　　 Judging from the armor on this Hiran Army soldier, it seems that he is not an ordinary soldier.

　　 Darlene felt that she was in a strange state.

　　 After 2 days of fighting, Darlene felt that her body became more and more relaxed.

　　 The stiff limbs became more flexible.

　　 Even the field of vision has a sudden widening feeling.

　　 Darlene's reaction became more sensitive and quickly sensed the enemy soldier.

　　 A shield blocked the enemy's attack.

　　 In the next moment when he blocked his attack, Darlene immediately slid towards the Hiran soldier like a fish.

　　 Darlene’s head was close to the body of the Hiran Army soldier, passing under his right armpit.

　　 When passing under the right armpit of the Hiran Army soldier, Darlene’s sword also swept across the side of the Hiran Army soldier along with her body.

　　 The sharp blade of the sword ran through the abdomen of the Hiran Soldier from the guard to the tip of the sword, and cut the Hiran Soldier in the waist.
