After knowing all this, for the sake of the future and continuation of the race, those races that have not yet been exterminated by the "sweeping force" immediately use various methods to contact each other, wanting to discuss a strategy that can resist the "sweeping force". Pen "Fun" Pavilion www.biquge.info

It's a pity that in the face of the "sweeping forces" with absolute strength, no matter how they deduce, they still can't find a strategy that can confront them.

So, on this day, after several urgent consultations, the left-behind high-ranking of the various tribes in Zoltra had no choice but to issue an extremely cruel order - to abandon all the old, weak, sick and disabled people in the tribe, and go to a certain cave that is easy to defend and difficult to attack with the young and strong people in the tribe, with healthy children and a large amount of water.

Then, gather the forces of all races, and take advantage of the cave's geographical advantages to join forces to resist the evil and crazy "sweeping forces".

――――――――――――――――――――――

On November 20th, after two days of sweeping, except for the extremely precipitous cave where the last seeds of the Zotra tribes were gathered, there was no trace of the activity of intelligent beings in the whole territory of Zotra - although the strength of the Zotra tribes had weakened to an all-time low due to the departure of the young and strong people in the tribe, the advance speed of the two "sweeping troops" was not accelerated.

This is due in part to the fact that the "mopping forces" need to carefully inspect every cave and underground passage to ensure that no fish slip through the net. On the other hand, it is because those old, weak, sick and disabled who were abandoned by the high-level of their clan, in order to buy more time for the evacuation of the young and strong people and children in the clan, desperately resisted the extermination of the "sweeping troops", so that the "sweeping troops" could not get up quickly.

Thus, even as early as the 18th, two "sweeping forces" had already swept three-fifths of the territory of Zatta. But it took them two days to sweep the rest of the area.

And although he didn't do it himself, Zhou Yunfei, who did kill hundreds of thousands of people, also broke two million merit points for the first time, reaching a terrifying 2.13 million -- among them, hundreds of thousands of civilians of various ethnic groups in Zottra brought Zhou Yunfei more than 1.5 million merit points, and as for the remaining hundreds of thousands of merit points, Zhou Yunfei exchanged them for various "treasures".

In fact, Zhou Yunfei himself only found out later that not all races are as rich as the Crypt Demons, and many poor races can't get much valuable even if they scrape the ground.

To be honest, if it weren't for the fragments of the magic diary, after exterminating those poor races, Zhou Yunfei probably wouldn't have bothered to raid their tribe. After all, the cost performance of this is too low, and if you have that time, it is better to end the dungeon quickly and go back to Fu City to hunt the zombies on the streets.

On November 21, almost ten o'clock in the morning, outside the nameless but difficult to defend cave. Two hours ago, Zhou Yunfei, who had just flown here from Chuck Lake, was suspended in mid-air at a distance of more than 20 meters, observing the cave not far away, or the underground passage into the cave -- Zhou Yunfei, who had been practicing how to fly these days, had basically mastered the tricks of flying and adapted to the attitude when flying.

Therefore, whether it is flying from Chuck Lake to this side, or suspended in mid-air, it is a piece of cake for Zhou Yunfei now.

The observation lasted for more than ten minutes, and when the observation ended, Zhou Yunfei had to admit with some helplessness that the tribes of Zedra had found a good place, and this cave was too dangerous.

First and foremost, there is only one underground passage in and out of this cave. Other than that, the cave doesn't have any normal passages, not even the kind of "passages" that only rats can walk.

Secondly, as the only entrance and exit passage, there are not only many natural bunkers in the underground passage, which can be used by those who enter the cave to defend against the invasion of foreign enemies. Moreover, these bunkers are basically at a high place, which allows the people in the cave to attack from the outside in a "descending" way.

In the end, the underground passage is divided into several sections, each of which is narrow on the outside and wide on the inside. As a result, those who invade from the outside have to face the dilemma of having to enter only a few people at a time, and the few who are the only ones to endure a bunch of people attacking - and most importantly, this dilemma is not experienced once and then gone. Instead, you have to go through it four or five times.

From the above brief description, it is very obvious how difficult it is to enter this cave from the outside.

It is no exaggeration to say that almost every part of this cave, or the underground passage into the cave, was born for defense. Coupled with the trap mechanism prepared in advance, "one man is the key to ten thousand people" is the best description of it - to be honest, if it weren't for the small size of the cave, and the only land it had been very barren, neither a large number of crops could be grown, nor many animals lived, I am afraid that such a treasure land would have been occupied by a certain race.

In this case, if he chooses to attack head-on, even if Zhou Yunfei has hundreds of high-level powerhouses under his command, and there are only a dozen crooked melon-like high-level powerhouses on the opposite side, it will still be difficult for Zhou Yunfei to win.

Even, even if he really wins, the casualties of the soldiers will be very heavy, which is obviously unacceptable to Zhou Yunfei - after all, how many people died after so many battles in front? If for this kind of final battle, more people died than before, Zhou Yunfei was afraid that he would be depressed and want to find a piece of tofu to die.

Therefore, a frontal assault is absolutely not a no-go.

So, is there any other way to capture the cave without attacking head-on?

Regarding this question, Zhou Yunfei just wants to say that there is no real fortress in this world. As long as you have enough troops, materials, and time, no matter how strong a fortress is, it will eventually be captured.

Take this cave, for example, as mentioned above, it has a fatal flaw - that is, the cave is small in size and the land is very poor, and it can neither grow crops in large quantities nor have many animals to live.

In other words, there is no possibility that this cave will produce a lot of food, let alone thousands of young people from different races, different sizes, and completely different amounts of food. Even a few hundred ordinary adult humans, if they want to survive here, must constantly get food from the outside world, otherwise they will starve to death.

Therefore, as long as Zhou Yunfei is willing, he will be blocked outside the underground passage for ten days and half a month, and those people inside can only take the initiative to attack, and the so-called "one husband should be closed and ten thousand people will not be opened" has become a joke.

However, Zhou Yunfei obviously doesn't have the time in the United States to block people here, so the plan of blocking the door is definitely not good.

As a result, there was only one road left for Zhou Yunfei in front of him -- to open up a new offensive line.
