As the sky grew brighter, more and more Liuguo monks gathered around the fortress, and it was clear that they were gathering strength and planning to launch a new offensive against the fortress.

Shi Yi hid in the distance and roughly counted, there were about 3,000 monks of Liu Guo who participated in this attack alone, and this only included the rotation and garrison personnel, after all, in the face of this protracted war, Liu Guo would definitely not drain all his strength, otherwise if the car overturned, it would be really troublesome if the follow-up was powerless.

However, these more than 3,000 people must also be the main force of the monks of the Liu Kingdom, and every time this kind of fortress is mastered by the Yan Kingdom for one more day, the difficulty of breaking through will inevitably increase exponentially, which is not easy for the monks of the Liu Kingdom.

Shi Yi was thinking that Liu Guo's side had already launched an offensive, only to see countless monks showing their abilities, and countless stone bullets, ice picks, and swords were like raindrops, hitting the fortress.

However, this seemingly ferocious offensive is really nothing to this fortress, these attacks can't break through the magic circle covering the fortress at all, at most it only makes the magic circle fluctuate, and as soon as the attack stops, the magic circle regains its calm, and it can't set off many ripples at all.

Seeing this, Shi Yi couldn't help but secretly say Sure enough, when he saw the huge sword marks on the walls of the fortress before, he had a question, this one had never been cut down when facing high-level monks, so you can imagine how strong the defensive ability of the magic circle here is.

Now, the Yan Kingdom and the Liu Kingdom have signed a treaty, and neither side can send high-level monks to participate in the battle, but the magic circle arranged by the high-level monks in this fortress is not restricted, so that if you want to break through this fortress with only the monks of the Fu Qi Period and a small number of Birthplace Realm monks, the difficulty will inevitably increase exponentially.

It was no wonder that they only saw the monks of the Liu Kingdom gathered here, but they did not see the monks of the Yan Kingdom coming out to meet them at all, because they were very sure that if the Liu Kingdom was only attacking at this level, even if they were allowed to attack, they would not be able to break through the defensive circle of the fortress, and everything would be in vain.

"The advantage taken by the Yan Kingdom here is really too great, if they keep cowering in the fortress, then our next plan will be in vain. Cui Zong saw that the attack of Liu Guo's side was useless, so he was a little breathless, and he asked Shi Yi with an anxious face.

"Rest assured, if there is no way at all, do you think that the Liu Kingdom will sign a contract with the Yan Kingdom, the high-level monks are not allowed to enter, and the low-level monks have no way to take this fortress, isn't this pushing themselves into a corner, if so, it is better to admit defeat as soon as possible, I think the high-level of the Liu Kingdom will not be so stupid, they will definitely have the means to deal with this situation, be patient." Shi Yi looked at the situation in the field with his usual face and looked at the situation with full attention, and casually said to Cui Zong.

Sure enough, just as Shi Yi said, after the Liu Guo side found that there was no way to defend the fortress, the monks standing in the rear began to quickly assemble some kind of equipment, and after a while, five huge ballista-like instruments were assembled.

Shi Yi looked at these huge siege equipment, his eyes couldn't help narrowing, this thing could appear in the hands of the monk, no matter how he thought about it, it couldn't be an ordinary ballista.

At this moment, all five ballistas were in place, and more than a dozen monks dragged the bowstring, pulling it little by little to the shape of a full moon, and with each step they went back, the whole bowstring became brighter by a minute, until the bowstring was fixed by many monks, and the ten monks collapsed to the ground completely tired.

Then a huge crossbow bolt was lifted out and installed on the crossbow body, the huge crossbow arrow at a glance made people feel extraordinary, the black inscription on it almost covered the entire body of the arrow, even if the sun was direct, the black inscription almost did not reflect any sunlight, the light seemed to be swallowed by the black part.

As the bolts were loaded onto the carts, the inscriptions on the arrows were lit up as if they had been infected, the end of the bolts touched the glowing bowstring.

At this moment, with an order, the sound of the machine also sounded, and the five crossbow arrows accompanied by a huge whistling sound, like five superswords, quickly attacked in the direction of the fortress.

With such a huge movement on the side of the Liu Kingdom, it was impossible for the monks of the Yan Kingdom stationed in the fortress to be invisible as long as they were not blind, and as the five crossbow arrows flew towards here, they also had a premonition that a crisis was coming.

A large amount of Yuan Jing was invested without counting the cost, and within the guardian circle, the defensive ability of the fortress was raised to the peak.

At this moment, the first crossbow arrow had already flown to the perimeter of the fortress, and as the tip of the crossbow arrow made contact with the circle, the light of the inscription on the arrow body shone more and more.

As the blue light grew brighter and brighter, the first crossbow exploded.

But before the Yan Kingdom side could breathe a sigh of relief, the crossbow arrow that exploded formed a blue film of light with the explosion, directly covering the entire defensive array.

Under the effect of the blue light film, the color of the defensive circle gradually dimmed and became almost nothing, and the second and third crossbow arrows were shot at this time.

Just as they came into contact with the fortress's defensive circle, at that moment, the blue light film attached to the defensive circle became dazzling.

And in this way, in front of the monks of the Yan Kingdom, the two crossbow arrows smoothly passed through the defensive circle and appeared in front of them.

As soon as these two huge crossbow bolts flew into the fortress, they displayed amazing destructive power.

I saw one of the crossbow arrows shot obliquely into the fortress, and then the inscription on the crossbow arrow exploded, and the whole crossbow arrow exploded violently, with the appearance of the inscription power, the fortress seemed to have encountered a tsunami, and a huge wave appeared out of thin air, directly destroying one of the walls of the fortress, and then still poured into the fortress.

Another bolt slammed into the top of the fortress, sending an endless wave of heat as it burst open.

Even if they were so far away, Shi Yi could hear the wailing sound coming from inside the fortress, and this time the monks of the Yan Kingdom must have suffered heavy casualties.

However, the offensive of the Liu State side was far from over, and the last two crossbow arrows were also approaching, just when Shi Yi thought that these two crossbow arrows would easily pass through the defensive array and enter the fortress as before, the Yan State side also launched a counterattack.

I saw that the two crossbow arrows shone with the blue light film covering the defensive circle, and then easily passed through the defensive circle as before.

Just as they were about to fly to the fortress, another earthy circle suddenly opened and collided head-on with the two crossbow arrows.

This earthy yellow circle was like a large elastic net, constantly deformed by the impact in the face of the huge power of the two arrows, but it always locked them firmly and did not allow them to enter the hinterland of the fortress.

As the shape of the earth-colored circle was stretched longer and longer under the impact of the arrows, a huge force suddenly came out of it, and under the effect of this huge force, the earth-yellow circle quickly recovered, and the two crossbow arrows were also bounced out, and one of the crossbow arrows was aimed at the place where the monks of the Liu Kingdom gathered.
