Three days and three nights, three days and three nights, and three days and three nights.

In addition, on the first day and night, Meng Zhang brushed the monster in the corpse cave for ten days.

Just as Kui Niu told him, no matter how much you kill the monster in this cave, it is impossible to kill it all, because after thousands of years of evolution, this place has become a place similar to the undead world, even if it is not worth mentioning compared to the real undead world, it is just a prototype of the undead world, but it is not something that Meng Zhang can shake in a short time.

In fact, having such a place where you can farm monsters is also a great thing for Meng Zhang, after all, if he wants to improve his strength, what he lacks a lot of time is psionic essence. As long as there was enough psionic essence, Meng Zhang would be able to push his own battle pets to the limit that the current order could reach.

After ten days of sleepless struggle, in this dark and gloomy cave, Meng Zhang brushed monsters and made people almost stupid. At this time, Meng Zhang didn't look like anything on his face, but the haggard in his eyes couldn't be concealed.

Fortunately, so many days of struggle were not in vain, and Meng Zhang's gains—strictly speaking, the gains of his war pets were extremely large, so big that they were beyond his imagination before he came here.

With enough psionic essence, Meng Zhang can increase the level of the war pet, and with enough psionic essence, Meng Zhang can make the war pets under his command forcibly break through the bottleneck of the product order, and then successfully improve the product.

Ten days and ten nights of struggle made every battle pet under Meng Zhang's command pile up to level seventy, even the spirit beehive. Under the infusion of massive psionic essence, the war pets jumped as fast as if they had eaten a golden carat.

If it weren't for the fact that Meng Zhang's rank was not high enough, so that the higher the level, the greater the consumption of spiritual energy essence, and in the back, it would increase tenfold and hundredfold, and the battle pets would definitely not stop at level seventy.

It is also level seventy, and the strength is also strong and weak, and the order is also high and low.

The strong can become the existence of the eighth order, and the weak can only be the seventh order. Although Meng Zhang really wanted his war pets to be the former, he couldn't help but his own rank was still far from the eighth rank of the ranks, so how could he ask for more war pets.

The pinnacle of the seventh order, one foot into the threshold of the eighth order, is actually very strong, after all, Meng Zhang's war pets are not one or two.

In terms of the improvement of strength alone, the ten days of hard work in the corpse cave have made Meng Zhang have a qualitative improvement. Although it has not achieved the achievement of being impressed by Shibei for three days, it can still be achieved for Shibei to be impressed for ten days.

In terms of assessing combat effectiveness, in terms of strength on paper alone, Meng Zhang has already left Kong Xuan behind.

But the strength on paper is only the strength on paper, and the actual battle cannot be completely relied on by this, after all, there are many factors that determine the outcome of the master's competition.

If he really wanted to fight, Meng Zhang was not sure that he could win against Kong Xuan, after all, Kong Xuan's ability was too special, and the group of golden lights that could kill and kill alone just restrained Meng Zhang.

No matter how strong your war pet is, you will be brushed into the golden light, and you will still be finished.

However, if he encounters the kind of enemy who does not have a super single-second ability, Meng Zhang, who relies on many powerful battle pets, can exert much stronger combat power than Kong Xuan.

Like Kong Xuan, do you have many existences with special abilities and super single-second abilities?

Not much.

Not only is there not much, but it is very few, so few that it is as rare as a few people, and it may not be possible to meet one among hundreds of millions of capable people. Therefore, Meng Zhang is now one of the very few people standing at the top, at least among the current Blue Star Terrans.

Continuing to stay in the corpse cave will not be able to improve the strength in a short period of time, Meng Zhang wants to improve his product order and only rely on the spiritual essence obtained by brushing the skeleton monster to save until the Year of the Monkey, so after learning about the situation, he did not have the slightest nostalgia, and directly summoned Kui Niu, let the latter open a spatial channel, and returned to Beachy City.

Back on the ground, the long-lost sunlight sprinkled on his body, which was very different from the dark and cold light and warmth in the corpse cave, dispelled Meng Zhang's mental exhaustion and made his state slowly improve.

When Meng Zhang, who had slept beautifully, got up again, he had already adjusted himself.

In the past ten days, when Meng Zhang was in retreat and cultivating and farming monsters frantically, Kong Xuan, who stayed at the base, was not idle. Jincheng's outer defense line has been built, although only the outermost defense line has been built, but according to Kong Xuan, the successful establishment of this defense line alone has given Jincheng the ability to resist foreign enemies. An enemy like the previous alliance of monsters of all races would be able to attack this line of defense without paying a heavy price. And the monster alliance that each has a ghost and wants to let others rush first, can desperately attack the solid defense line established by humans?

Not to mention that it must be impossible, the odds are too small, unless one of them has an existence that can suppress the field with absolute strength.

With a strong enough perimeter to keep out the external threat, the interior of Jincheng can rest assured that they can rebuild a new city from the ruins, just as they once did in the Third Base City.

Jincheng is like this, and the progress on the Bacheng side will be slower.

Because it was a newly recovered city, Meng Zhang attacked more ruthlessly, and almost burned the entire mountain forest, although it was to avoid the effort of clearing the forest during reconstruction, but it also increased the difficulty of reconstruction, because many times it was impossible to use local materials. In addition, the big mushroom planted when Bacheng attacked the four demon generals, it is not biased in the center of Bacheng, and the radiation after the nuclear explosion has not dissipated much at this moment, and it is not suitable for people to approach, which makes it more difficult to rebuild Bacheng.

Although Sun Bo and Gao Daqiang have been rebuilt, they have only occupied a few small hills and built a military camp on them, which can be regarded as announcing that Bacheng has returned to the human race, and outsiders are not allowed to touch it.

But what makes them feel helpless is that their announcement has not had much effect, the monsters near Bacheng always love to wander around the barracks, and from time to time they also launch tentative attacks, which have the meaning of probing the Bacheng garrison and taking the city at the first opportunity.

If this happened in Jincheng, Kong Xuan would teach those monsters to be humans, but Sun Bo and others in Bacheng did not have the ability of Kong Xuan, and they could often only defend passively.

Seeing the human garrison like this, the monsters who have tried many times have become more and more arrogant, more and more unscrupulous, and I think that in the eyes of the monsters, the human garrison in Bacheng has become a soft persimmon, the kind that can be manipulated by them. As a result, more and more monsters gathered near Bacheng, and their number exceeded that of the Bacheng garrison by more than ten times.

Sun Bo and the others estimated that if this momentum continued, it would not be a few days before the monsters would launch a large-scale attack on the barracks.

Once again, the clouds of war loomed over Ba Cheng.

However, with the arrival of Meng Zhang, all this seems to be about to change again.
