The NPCs didn't know what Zhou Tian was planning, and of course they wouldn't care about it. For the NPC leaders in those levels, just how to remove the tension of their soldiers is enough to give them a headache.

"Attack!" Just when those NPCs were nervously doing all kinds of work, hoping to increase their chances of winning through those preparations, and feeling that the other party was basically ready, Zhou Tian also gave the order to attack at that time.

With Zhou Tian's order, soon the orc army also launched a general attack on that level.

"Buzz ......" A piercing sound sounded, and when those NPCs looked in the direction of Zhou Tian, they also saw that they were in front of them for some time, and they had already been blocked by the rain of arrows. Then the NPCs didn't have time to prepare too much when the orc archers' attacks fell on their heads.

The sound of arrows entering the body sounded, and even if each of the more than 200,000 orc archers launched an attack, it would be a long-range attack of more than 200,000 yuan. Not to mention that the strength of the current orc archers is already good, even if the strength of those orc archers is weak, in the face of such a number of attacks, it is completely enough to cause considerable losses to those NPCs.

In fact, although the NPCs on the level also made defensive measures in the face of the attacks of the orc archers. But depending on their strength, even if they were prepared, they would not be able to block such an attack. Therefore, when hundreds of thousands of arrows fell into the level, those NPCs who were on the level at that time directly let them kill most of them.

Moreover, after successfully killing those NPCs, the orc attack did not end. When the orc archers unleashed a second and third wave of arrows, killing all the NPCs standing on the level, a group of orc warriors who launched the charge had already rushed to the bottom of the level.

Maybe those NPCs should be thankful, but luckily they have always relied on teleportation arrays to communicate with the outside world, so they didn't leave a door when building the level. Otherwise, if they had left a gate at this level like those cities, and let the group of orcs rush under the city wall without being prepared, then this battle would basically be over.

Because there is no city gate, even those orc warriors who have already rushed under the wall have no way to enter the level and slaughter those NPCs. At that time, there was only one thing they could do, and that was to attack the level with the weapons in their hands, and they wanted to destroy the NPC's fortifications with their attack power.

Undoubtedly, what the orc warriors want to do is not impossible. But for one, their attack is not suitable for destroying buildings. Second, the city wall of that level has a terrifying amount of blood, and those orc warriors have been beating for a long time below, but the city wall has not shed much blood in the end.

However, no matter how destructive the orc warriors are to the level, if the NPCs in the level are left to their own devices. Then there is no doubt that even if it takes a long time, in the end, that level will still be broken.

Of course, those NPCs in the level naturally couldn't give up the victory to Zhou Tian so easily. So, when those orc warriors slammed around the wall around the level, those NPCs hurriedly reacted to it.

Because of the suppression of the orc archers, those NPCs at that time really had no way to stand on the city wall safely. However, the number of attacks of orc archers is also limited, so even if the rain of arrows attack is really terrifying, those NPCs are not intimidated by their attacks, but actively respond at that time.

Except for the first three attacks, which were collective volleys of orc archers, although the attacks of the later orc archers were said to have suppressed those NPCs, their attacks were already somewhat scattered at that time. At that time, the attacks launched by the orc archers were almost always in batches of spot shots at the NPCs on the top of the level.

Undoubtedly, the actions of the orc archers were due to the limited number of arrows in their hands. But just when the orc archers had to change their attacks, they gave those NPCs a chance to breathe.

Now that there are fewer attacks, the orc archers' suppression of those NPCs will naturally be weakened as well. At that time, as long as the NPC side does not dispatch too many centaurs at one time to cause the attack of the orc archers, then even if they appear on the level, they no longer have to worry about being killed by those orc archers in a salvo as before.

And according to the situation at that time, for those NPCs, stopping those orc warriors from destroying the city wall has become their most important task. As a result, in that case, when the group of orc warriors attacked the city wall for a while, a group of NPCs soon appeared scattered on the level. At the risk of being shot by the orc archers, those NPCs attacked the orc warriors below without hesitation.

The NPC side naturally also has its own long-range attack ability, although there is no way to launch a counterattack against Zhou Tian's orc archers because their long-range attack power is not as good as that of orc archers. But if those NPCs want to attack the orc warriors below, there will be no problem at all.

As a result, the group of NPCs was on the level, and while guarding against being shot by the orc archers in the distance, they directly attacked the NPCs below them with various abilities.

Magic and bows and arrows were dispatched in unison, and attacks from top to bottom continued to fall into the ranks of orc warriors, and as a result, under that kind of attack, Zhou Tian's orc warriors suffered heavy casualties at that time.

In the face of the casualties of his orc warriors, Zhou Tian didn't seem to care about it at that time, just watching the siege battle coldly from the rear, as if he was ready to use this way to capture that level.

As a result, in the absence of a new order from Zhou Tian, those orc warriors could only follow Zhou Tian's previous orders to continuously attack that level against the attacks of those NPCs. Although each of their attacks was accompanied by a large number of casualties among their companions, no matter what, the fruits of the efforts of those orc warriors were still visible on Sunday.

It wasn't until that the battle lasted for more than an hour, and after Zhou Tian paid the price of tens of thousands of orc warriors killed, the blood volume on the wall of that level finally dropped to less than one percent. Seeing this, Zhou Tian gave an order, and he also sent those orc knife (spear) soldiers on both sides out at that time.

"Kill!" The dispatch of the orc knife (spear) soldiers was like a catalyst, directly pressing the balance of victory on Zhou Tian's side.

After all, in the previous war, those NPCs had already suffered most casualties due to the attacks of orc archers. And in this case, when the city wall was about to collapse, there was a new force on his side, and the orc warriors had knocked down a lot of walls with a concerted effort. In that case, those orc knife (spear) soldiers followed the orc warriors into the interior of the level, so that those NPCs had no ability to resist.
