Whoosh -

In the battlefield of Nuoda, no one noticed the fall of this bullet, but in the next moment, everyone felt a ringing in their ears, and a piercing light lit up from the eastern corner of the city, and even Chen Xiao, who was far away in the west, lost his mind for a short time......

This is the secret weapon prepared by Tian Yang?

Unlike Chen Xiao or most of the people in the academy who only strengthen themselves, the mechanical flow taken by Tian Yang is exactly the same route, listening to Chu Qianqian, Tian Yang's dormitory has now become a laboratory, and he can already buy raw materials by himself and make powerful explosives. Pen, fun, and www.biquge.info

The blinding white light was followed by a violent roar, and countless orcs and small monsters such as bulls and lions were blown into the sky, and then fell down heavily, turning into flesh and mud, and the frozen plain rolled up a thousand layers of earth.

"Yes...... The other party's ballista?! Tian Lu, the thin man in charge of the command of the eastern city wall, had a little fear on his face, the power of such an explosion, if he rushed forward rashly, he would have to shed his skin if he didn't die.

Hurriedly gave the order to retreat from his heart, he had just been defeated yesterday, and he didn't want to take the blame again today.

But......

The order was given a step too late, and after the first wave of explosions, just as the monsters that had survived were dancing, the second wave of real terror came.

Because it was winter, although the surface of the plain was frozen hard, the soil below was extremely soft due to the penetration of snow water, and after a violent explosion and vibration, it collapsed like a chain of chains, and the entire hundreds of square meters of land under the eastern city wall became a swamp.

"The dragon slaying cannon of the arrow tower is ready, and before the other party escapes, it will be annihilated in one fell swoop!" Asuna's eyes lit up, she knew that this was the best opportunity, and hurriedly contacted the arrow tower, which also quickly gave her response.

"I didn't expect you to be quite powerful, are these all arranged by you? Why haven't I seen it in the game world, it costs a lot of gold, right? Asuna looked at Tian Yang, who was relaxed and freehand, and her attitude towards him changed.

"That's nature, it's my unique technique! It is impossible for them to escape from the quagmire. ”

Tian Yang hugged his arms a little proudly, while looking at the situation below, and saw that some big guys were about to climb up from the edge of the quagmire with brute force......

"Secret Weapon No. 2!" Tian Yang waved his hand to the players in charge of the reserve of war supplies in the corner tower behind, and after listening to the creaking sound, the players launched a crossbow machine with a small wheel, and a row of metal arrows on it exuded a cold cold light, which was chilling to see.

Trained players quickly wound and aim.

"Report, shooting ready!" A young player debriefs loudly.

"It's ...... Ballista? Asuna recognized the equipment in front of her, compared to the bow and arrow, the ballista did have the characteristics of fast fire and strong power.

"This isn't your average ballista, I've improved it." Chen Xiao waved the flag in his hand and motioned for them to shoot at the monster that crawled out of the quagmire.

Whoosh!

Not understanding what was going on, an orc who had just crawled out of the quagmire suddenly fell to the ground with a scream, a crossbow bolt stuck in his chest.

Immediately afterward, the monsters were hit by arrows one after another, and lay around the quagmire.

It wasn't over yet, the bolt pierced their bodies and plunged into the ground, and a little spark lit up at the arrow, and then—

Crash Crash!

A series of small explosions!

The metal arrows were exploded, like scattered petals, forming a terrible metal storm, the flesh and blood were as fragile as paper, and those low-level monsters with almost poor defense didn't even have time to scream, and they were instantly crushed to pieces.

Only a tough skin like a recluse beast can barely withstand this barrage attack.

"It's still a little bit less powerful." Tian Yang shook his head with some dissatisfaction, the world of Sword Art Online restricted the manufacture of firearms, and the high-efficiency clay gunpowder that caused the big explosion just now was all he brought from the academy.

These ballistas only have small bombs hanging on the arrows, and the arrows are designed by Tian Yang to have a gap in the middle and can be split.

"That's enough, it's almost time." Asuna looked in the direction of the arrow tower behind her, if she used the dragon slaying ballista to clean up this large number of monsters, she could also withdraw to support Chen Xiao......

Rumble!

There was still a sound like the earth shaking, and a blue magical light lit up at the arrow tower, followed by two magic cannonballs that accurately hit the monsters trapped in the swamp.

The fire is shining and the flesh is flying......

The monsters howled and screamed, and were pushed to the ground by the huge waves of air, and trampled on each other; A miserable cry was heard far away, not like a battlefield, but like a slaughterhouse.

In the blink of an eye, nearly a thousand monsters were blown to powder!

Seeing that only two more cannons were needed to completely annihilate the troops besieging the eastern wall, the arrow tower seemed to suddenly mute and made no sound.

"Keep firing! Now is not the time to save ammo! Asuna shouted sharply from the communication channel to the Arrow Tower.

But for a long time, there was still no movement.

"How so? This is the most critical time in the battle, and they can't afford to neglect their duties! Asuna's expression suddenly tensed, and her eyebrows furrowed together.

"I'll check it out! Just now I felt as if something had passed. Kirito said coldly in the channel, and after getting Asuna's consent, he led Yuki and Klein to run in the direction of the arrow tower in the inner city.

The news of the loss of contact with the arrow tower quickly spread in the communication channel, making the players who were already under siege pressure feel worried.

How did the other party sneak in? To what extent the arrow tower has been attacked, and whether it can still have the strength to support itself, these countless questions weighed on everyone's minds.

On Chen Xiao's side, Chu Qianqian's magic was finally prepared.

"Retreat!" Chen Xiao got the hint and quickly led the players who were still in the bloody battle to retreat, giving up a large section of the city wall.

The meat ball girl was overjoyed, but when she had not yet sent an additional team to consolidate this position, from the sky above the city wall, it seemed to crack a gap, and a rushing river rolled out, rushing out of the city, rushing quickly towards the orcs and wasps who were still standing in place......

This kind of low-level spell, although it is not lethal, and it does not have much effect on those heavy monsters, but it is really the best to deal with these orcs and metal bees, and only to hear a whining scream, those monsters are rushed down the city wall, and the bones that fall to the ground are broken.

The metal bee's wings were also stained with water, unable to maintain their flight status, and they fell one after another, and the situation on the western wall eased, and the players regained control of the city wall!
