With enough troops, those undead monsters are useless even if they have an advantage in strength, in front of the half-orc warriors under Zhou Tian who died and replaced a batch of human sea warriors, how could those undead monsters at that time be able to support it.

At first, because of the battle, most of those undead monsters were only slightly injured. However, as the battle heats up, when more and more orc warriors continue to pour in, without time to rest, it is impossible to kill one or two orc warriors, and those undead monsters will not be able to kill all the orc warriors they encounter intact. As a result, with the continuous transformation of minor injuries and serious injuries, in the end, when the blood volume bottomed out, those undead monsters fell one after another under the sticks of those half-orc warriors.

And when more and more undead monsters died in the hands of Zhou Tian's half-orc warriors, it also meant that Zhou Tian's control over the Skull Cave was already getting bigger and bigger. And when the control is greatly increased, the pressure on Zhou Tian's rear will be lighter, not only are there fewer and fewer undead monsters attacking them in the skull cave, but even many orc warriors under Zhou Tian who had nothing to do at that time asked him to summon him to help him resist those high-level undead monsters.

In the end, Zhou Tian held out for nearly a week, and he didn't know how many casualties he paid, so he wiped out all the undead monsters in the Skull Cave at that time, and officially regained the dominance of the second layer of the Skull Cave.

And after things have progressed to this point, it means that Zhou Tian's first intention has been achieved. Now, as long as Zhou Tian finds a way to block those undead monsters from the entrance passage of the Skull Cave, then the crisis in the Skull Cave will basically be eliminated by him.

It's just that the problem now is that Zhou Tian wants to keep those undead monsters out of the skull cave.

Although Zhou Tian had thought that it would be such an ending before, he was also prepared to let his half-orcs use manpower to block those undead monsters from the passage. However, when Zhou Tian originally planned those plans, he seriously underestimated the strength of those undead monsters. In this way, under the current situation that the enemy's strength is obviously beyond the plan, Zhou Tian's original arrangement is a bit risky.

"If you don't hold on in the end, it's going to be miserable." Thinking of the benefits and disadvantages of those undead monsters, Zhou Tian knew that according to the strength of those half-orcs under his command, if one was not good, maybe it was really possible that those undead monsters would attack the skull hole again, and once that situation occurred, it would mean that the results of Zhou Tian's current efforts would be lost, and in the face of such a situation, if he had a choice, Zhou Tian did not want to take that risk.

It's just that Zhou Tianzhi said that he didn't have too many options. If he stays, it will indeed ensure that those undead monsters can't enter the skull hole for a short time. But in the same way, if Zhou Tian is tripped here, then don't say that his strength will not increase in any way, and even the source of soldiers will be exhausted. In this way, even if there are no problems in a short period of time, it is unlikely that Zhou Tian will end up with any good results.

Therefore, instead of staying where he is at this time, Zhou Tian is willing to take another risk and hand over this skull hole to his subordinates to defend. In this way, the worst result is to lose the territory of the Skull Cave, as long as Zhou Tian can grow his strength rapidly, then these undead monsters that seem incomparably powerful to him at the moment will one day be trampled under his feet.

Now that a decision has been made, Zhou Tian's speed of action is also fast.

After directly leaving all the remaining orc warriors in his hands on the second floor of the Skull Cave, Zhou Tian only took away a small number of orc warriors, but he also left ninety percent of the combat power of his clan in the Skull Cave.

Zhou Tian laid several lines of defense in the Skull Cave, and the passage from the lair of those undead monsters to the Skull Cave was the first line of defense. The entrance to the second level below the first level is the second line of defense. There is also the entrance to the Skull Cave that has also been made into the third line of defense by Zhou Tian. In this way, as long as the three lines of defense arranged by Zhou Tian are not breached, then even if something happens in the final skull cave, Zhou Tian believes that he will not really let those undead monsters attack his powerful abdomen easily.

After making all the preparations, Zhou Tian withdrew from the city at that time.

However, after really withdrawing from the gang, Zhou Tian was distressed again at that time. Because now he has just solved the problem in the skull cave, and in the blink of an eye, he must solve another problem.

In order to deal with those undead monsters, Zhou Tian must improve the strength of his half-orc clan, and the way Zhou Tian thought of at that time was to take over some of the more hot territories. Right now, Zhou Tian relied on his advantage in occupying those territories to the point that the strength of the half-orcs under his command had increased a lot, and finally snatched the skull hole back from the hands of those undead monsters. However, the consequences of Zhou Tian's original behavior were already beginning to be reflected at that time.

Zhou Tian's series of actions all have a lot of risks, in the case of so many troubles coming to the door at one time, in order to deal with those troubles, Zhou Tian is gambling with his own life. Now, as long as there is something wrong with any link in his plan, he is afraid that he will immediately encounter a series of blows. Whether it's Zhou Tian or the orcs under him, it is estimated that they will not want to exist.

And among Zhou Tian's series of actions, the most risky one is naturally the act of occupying part of the territory of the beast monsters.

Although Zhou Tian's actions in the Skull Cave seem to be risky, if they fail in the end, Zhou Tian has a good chance to retreat. And according to the situation at the time, the worst case scenario for Sunday would be to lose a skull hole.

And unlike the situation in the Skull Cave, Zhou Tian's actions after occupying those territories in order to deal with those undead monsters were really gambling on his own life.

Zhou Tian only won a heavy reward after just beating a small NPC village, and it can be seen from that that what kind of point the battle between monsters and NPCs has reached. And just like the case of rewards, Zhou Tian can get a heavy reward for defeating an NPC village, and if he loses a piece of territory, then he will definitely be punished fatally.

Originally, Zhou Tian's plan was to eat those NPCs who were not good at occupying their monsters' territory, and at the same time he was not prepared for his actions before he dared to do so. But no one can guarantee that there will be no accidents in the end, and if there is any accident, if there is any mistake in that territory, Zhou Tian will be unforgivable.
