Immortal Space

  Chapter 687 Retreat

  After these flying monsters were suppressed by the air-forbidden formation, they fell directly into the poison in front of the city wall.

  This piece of poison is not polite to the food that falls from the sky, and they all show their magical powers and hunt these monsters.

   By the time these flying monsters escaped from the range of the poison, there were not many left.

  The attack failed this time, and the Yaozu survived for another day.

  Afterwards, when the monsters attacked again, they changed their attack method to a feint attack elsewhere, concentrating on attacking a section of the city wall.

  This attack method actually caused some troubles for the defending army, but if they wanted to conquer the city wall, they still couldn't do it.

  The two sides fought fiercely all day, the Yaozu suffered heavy casualties, and the poison under the city wall was also destroyed a lot.

  In the days that followed, the Yaozu tried various tactics one after another, but they all failed. The Yaozu suffered countless casualties. Due to the distance, there have been no casualties among the cultivators on the city wall.

  Only the poisons under the city wall were destroyed, which is inevitable. After all, these poisons are still relatively fragile, and the new planting years are not enough.

  After exploring for a period of time, Yaozu also summed up some effective attack methods.

  Now they are no longer eager to rush under the city wall, but actively attack the poison on the ground every time.

   It seems that they are going to clean up the poison area in front of the city wall first, or at least clear out a few safe passages.

   And the monks on the city wall would naturally not let them be destroyed. All the giant crossbows were fired one after another, causing the monsters to fall one after another.

  The higher-ups of the monster clan didn't care much about the death of these low-level monster beasts, and let these monster clan step forward on the corpses.

  After a month, after paying the price of many low-level monsters, the Yaozu finally opened several safe passages in front of the city wall, leading directly to the city.

  Then they used these safe passages as a basis to launch focused attacks on the city walls, while constantly widening the safe passages to allow more monsters to pass through.

   Now these monster races can finally attack below the city wall. Sometimes they are lucky, and occasionally they can hurt the human monks on the city wall.

   In this regard, the higher-ups of the Yaozu are still very pleased. At least their previous attacks were not in vain. As long as they persist in this way, even grinding can grind down this layer of walls.

  As for the monsters that died, it is estimated that even their parents would not be sad about it.

  Here, most of these low-level monsters come from the sea, and their weak strength can survive in this cruel world of cultivating immortals.

  The main reason is because of their strong reproductive ability, they are used as food by high-level monsters every day, and they can still continue to this day with a huge number.

   It is already very good to be able to achieve such a result by wasting some low-level monsters.

  The battle continued in this attrition. Three months have passed since this dozen, and the poison in a large area under the city wall has been cleaned up by the monsters.

  The number of monster beasts has also decreased by at least 20%. Even cheap low-level monsters can't afford such consumption.

  In the past few days, the monster clan's attacks have suddenly become violent. They have been attacking for five consecutive days and have never stopped.

  Below the city wall, the corpses of the monster clan piled up higher and higher, almost reaching the height of the city wall.

  The purpose of the monster clan is very clear. They will use the corpses of these low-level monsters to pile up a slope, and then they can rush up the city wall along the pile of corpses.

  This method is a bit stupid, but it works.

   Moreover, most of the monsters in the sea are large in size, and it seems that a lot of them died. In fact, they have not died as much as when the safe passage was opened before.

   At this time, some monster races were able to rush up the city wall, and then beheaded by the soldiers on the city wall.

  The main attacking parts of the monster clan were only a few points, and they were shot and killed by countless arrows before they attacked the city wall.

   Only a small number of monster races can really attack the city wall alive.

  The army of the Great Chu Immortal Kingdom is not vegetarian either, they all lined up and waited for the monsters rushing forward.

  The few monsters that could charge up the city wall were quickly beheaded.

   Although the enemy is not very strong in such a battle, it should look easy.

   But this situation has continued. They have persisted for five days so far. Even if it is killing pigs, it will be very tiring to kill pigs even for five days.

  Although their defensive team was also divided into three rotations, such continuous fighting for several hours also made people feel extremely tired.

   Fortunately, Qizhou Island is not short of all kinds of resources at present, and the spiritual wine for replenishing mana and the elixir for healing can be distributed to everyone in a timely manner.

  The two sides maintained this fighting state, and another five days passed. At this time, the monsters had been attacking the city for ten consecutive days. During these ten days, they never stopped for a moment, and more and more slopes were piled up with monster corpses.

  At this time, the soldiers on the first city wall were exhausted.

  The reason why they fought continuously for ten days was that they were the only ones who were tired, but the Yaozu was not tired. It was because the Yaozu died one batch and then replaced them.

  At this time, a group of monks on the city wall were dismantling the giant crossbows above. After removing these giant crossbows, they put them in storage bags and took them away.

  In the current situation, if you insist on defending, the first city wall can be defended for another ten days and a half months without any problem.

   It's just that the defensive advantage of the first city wall is gone now, and the death Jedi composed of poison in front of the city wall has been completely destroyed.

  The height advantage of the city wall is also filled by the **** formed by the corpses of monsters, and the monsters can easily rush up the city wall.

   Therefore, Qizhou Island has planned to abandon the first city wall and retreat to the second city wall.

  Anyway, there are still two identical city walls at the back. Even if all three city walls are lost, Qizhou Island still has a nine-cursive formation that can be used, which has sufficient strategic depth.

  Since they plan to retreat, they will naturally remove all these giant crossbows and take them away.

  These giant crossbows still need to be installed on the city wall on the third floor. The giant crossbows have already been installed on the city wall on the second floor, and there is still an army stationed on the city wall on standby.

   Wait until all the crossbows on the first floor of the city wall are removed, and then they will retreat.

  Under the current situation, it is not an easy task to safely withdraw from the battlefield from the city wall.

   It is easy to be chased up by the Yaozu from behind, and the team that stays behind to cover is generally more or less fortunate.

   It seemed that the human race on the city wall wanted to retreat, and the monster race's offensive suddenly became more violent.

   Tier 3 monsters that rarely appeared before have emerged from the herd.

  However, the fate of these third-tier monsters is not that good. They often show up, and to meet them, dozens of short spears or flying swords shoot at them.

  Behind the group of monsters, the blond man from the Shemale Alliance was obviously very proud of this scene, "Hahaha! We haven't done anything yet, this city wall is about to come down."
