Luck was a part of one's strength, and these words were still valid in the apocalypse.

Yun Tu never thought that a life threatening escape would end in such a dramatic manner.

With the death of the Bone Devil, the formless threads that were controlling the zombies began to loosen up. The first level Black Scar hadn't gained intelligence, so it didn't feel anything, and it didn't know fear. However, the third level Purple Hair and the second level Green Hair felt their hearts tremble.

The Rank Four Bone Devil's entire body was naturally a treasure. Although the Bone Devil's head was already in Yun Tu's hands, when he sensed that the danger had been resolved, he would naturally want to pull the body out as well.

It wasn't easy to deal with the Bone Devil's corpse. Luckily, there was still space in the bracelet. Yun Tu took off one of the Bone Devil's leg bones and started grinding Black Back's teeth. The rest of the leg was stored into the bracelet.

The battle between Yun Tu and Feng Ling was over. The battle between Feng Ling, Ghost Foot, and the other two had only just begun in the secret realm.

According to Yun Tu's strategy, although they had successfully broken through the barrier of the Heavenly Sacrifice Tower's secret plane, they had encountered two purple-haired zombies in the Flower Garden Hotel. Before they had entered the secret plane, the two men at the back had already been severely injured.

A party would usually encounter small scale attacks the moment they entered the secret realm. Fortunately, this secret realm was a secondary palace for Feng Ling, so she had some understanding of the environment of the secret realm.

When the barrier between secret realms flashed, it hadn't even been a minute since everyone had entered the secret realm, but the first wave of attacks from the vicious beasts had already arrived in front of them.

"Feng Ling, what's going on? Didn't you say that the first wave of attacks was only four Level One Red Feathered Beasts? Why are there so many of them this time? Are you joking with us on the battlefield?" While fighting with all his might, Wang Ze couldn't help but ask.

It was obvious that the situation they were in was quite different from what Feng Ling described before they came in. Although the berserk beasts were of the same type as what she said, there were still more of them and their individual strength was not at the first level.

"I don't know either. They were both Level 1 last time, but this time, most of the attacks were Level 2!" When they were at the gate to the secret realm, they were certain that aside from the Quest Boss, Feng Ling, who was usually not too difficult, was not able to understand what was going on.

The secret plane was a mysterious place that was hard to understand. However, as time passed, the creatures inside would become stronger and stronger. This rule was explained more accurately by humans later on as their overall strength increased.

This point was something Cloud Diagram had never reminded anyone before. In addition, no one had repeated their experience of entering the same secret plane many times before, so the situation suddenly changed. The four who were not mentally prepared appeared to be in a hurry.

Although they were wounded, they were all level two masters with superior equipment. It was impossible for them to not be able to withstand the first wave of attacks. After a bitter battle, the four of them still managed to kill the first wave of vicious beasts.

According to Feng Ling, after surviving this wave of attacks, as long as they looked at the tallest mountain in the distance, they would be able to find the Heavenly Sacrifice Tower after traversing more than ten li of the mountain paths in the valley, and even after reaching that peak, the process would be basically safe.

In any case, there weren't any other teams fighting for the Heavenly Sacrifice Tower's secret plane. In addition, the Quest Boss was a Level 4 Ferocious Beast. For safety, Wang Ze decided to wait until everyone's wounds recovered before moving on.

No one objected.

After Xi Ke's Alchemy Skill reached level 3, as long as he had the necessary ingredients, he would be able to concoct a level 3 medicine at any time.

They were originally only missing the third grade zombie blood crystals. Just now, they had already killed several third grade zombies and collected several third grade blood crystals. Now, everything was in order.

While everyone was recuperating, Xi Ke started to concoct the new level 3 potion.

Everyone had high hopes for advancing to the third rank, but on the outside, Xi Yue did not bring all of the stored crystals from the Dark Night Guild with her. Now that the crystals from the magical beasts were insufficient, Xi Ke could only concoct two potions to advance to the third rank.

Out of the four of them, how were they going to split the two potions? If only Yun Tu was listening to him, then everyone else could use the first potion since Yun Tu was not around. The reason was that she was the weakest at the moment and had made the potions herself.

However, Xi Ke rejected everyone's good intentions.

This isn't good, all the good steel needs to be used on the blade edge, all the level three potions are used on me, so its usage is relatively limited. The secret realm is not safe, and once I arrive at the Heavenly Sacrifice Tower, killing the BOSS will not be easy, so I'll be able to safely pass the challenge as my priority.

No one could refute Xi Ke's refusals. To be the first to be promoted to the third rank meant that they had to be even more responsible for the team's safety. Everyone understood this point very well.

The reason was very simple. Feng Ling was the original founder of the Dark Night Guild, she had been with Cloud Diagram the longest, and had gone through many battles for the guild's development. Her battle awareness and fighting ability were both tested and recognized.

In addition, in terms of attacking the Heavenly Sacrificial Tower, in the internal battles, there was no difference between archers and no classes. In order to face the upcoming situation, he would have to pay a second potion to maximize its effect.

After deciding on the distribution of the potions, Xi Ke, Ghost Foot's Three Protectors, Feng Ling and Wang Ze swallowed each other's potions. After an hour, both of them successfully advanced to the third level.

Although they had entered the secret realm to seek refuge, they had entered the secret realm and were unable to leave until they had killed the BOSS. The strength of the party had greatly increased. The four of them congratulated each other and the party had set off again.

After having once entered the Heavenly Sacrifice Tower's secret plane and led the way, Wang Ze went to the back of the hall and easily walked on the familiar road, killing his way towards the direction of the Heavenly Sacrifice Tower.

Although it was only a few sporadic attacks, most of the mystic realm creatures they encountered were level two creatures, and two of them were level three opponents. If not for the fact that Feng Ling and Wang Ze Sheng were level three, it would have been difficult for them to reach the foot of the mountain where the Heavenly Sacrifice Tower was located even if they had not broken out of the secret realm and obtained the prizes.

Although the environment of the mystic realm was the same as last time, it was clear that the strength of the mystic realm vicious beasts had greatly increased. A few hours later, the four of them arrived at the Skysplit Tower once more.

"The last time I went there, all the mystic realm creatures were level one, but the Mystic Tower's quest BOSS was level four King Kong Wolf. Now, all the creatures on the way here have levelled up, so wouldn't that mean that the Heavenly Sacrifice Tower's ninth floor's quest BOSS has also levelled up to level five?"

If that's really the case, then it's impossible to break through the secret realm with just our two third rank and two second rank teams. "

As they sat down at the foot of the Heaven's Altar to rest, Feng Ling voiced out her thoughts. In fact, everyone's thoughts were about the same.

Entering the Heavenly Sacrifice Tower's secret realm was originally something that the zombie horde could do nothing about. It seemed that entering the Heavenly Sacrifice Tower's secret realm would temporarily remove the danger, but how were they supposed to deal with this new situation? The four of them looked at each other in dismay.

"Boss Yun Tu's foresight is like that of a god, why don't we not rush into the Tower of Heavenly Worship first, if we don't get out after a long time, after boss gets out of danger, he will organize pockmarked Zhang Feng and Steamed Bun and come in together again. When that time comes, the two squads of eight will work together, so even if it's a fifth level berserk beast guarding, it's not something to be afraid of!"

Wait!

It seemed like a hopeless strategy, but in their current situation, it was the safest. Besides, they didn't have a better plan.

Although they were only waiting, they were not lonely. On the road just now, they killed two level three berserk beasts, missing a level three energy crystal, and Caesar was able to produce a new drug to improve his strength. Each more person to level up, the team would become stronger, and they would definitely not miss this good fortune.

After resting for a while, everyone once again went to hunt in the forests surrounding the Heaven's Sacrificial Pagoda, preparing the ingredients for Xi's medicine.

However, what they didn't know at the moment was that the designer of the secret plane wasn't an idiot. If everyone could live inside the secret plane without breaking it, then the secret plane would become a refuge for humans. This obviously didn't match the original intention of the designer of the secret plane.

After a few hours of hunting in the secret realm, when everyone in the group had grown to the third level, the time they spent in the secret realm was already more than twice as long as the time they spent in the secret realm with Yun Tu. Moreover, at this time, the density of the vicious beasts in the secret realm was also more than twice as high as the time they spent in the secret realm.

Everyone had just levelled up to Level 3 and wanted to show off their skills. At the beginning, everyone was fighting very hard, but not only did they train themselves, they also gathered large amounts of energy crystals and various raw materials for the guild. They were all very excited, but after a while, Wang Ze felt that something was wrong.

"We can't go on like this. There are more and more vicious beasts in this mystic realm. When the density of the vicious beasts in the forest reaches a certain point, a beast tide will form. At that time, no one will be able to withstand it!"

This was a new development that no one had expected. After the four of them killed a group of ten or so vicious beasts, everyone fell into silence once more.

At this time, a group of vicious beasts larger than the group they had just beheaded began to surround them. Four third-level vicious beasts led the group, and the number of second-level vicious beasts numbered more than twenty.

"Retreat — — Kill and return to the Heavenly Sacrifice Tower. We'll rest at the first floor of the Heavenly Sacrifice Tower!"

The last time they had fought in the Heavenly Sacrifice Tower for so long, not a single beast had rushed in. It was clear that the wild beasts in the forest couldn't enter the tower, and Feng Ling's experience played an important role in determining the situation.

Although they were currently about a mile away from the Heavenly Worship Tower, the four Level 3 experts didn't keep fighting. They quickly rushed back to the Heavenly Worship Tower, and at this time, there were already 30 to 40 vicious beasts following them.

However, when they pushed open the gate to the Heavenly Sacrifice Tower's secret realm and entered the first level, everything was exactly as Feng Ling predicted. However, when they pushed open the gate of the Heavenly Sacrifice Tower's secret realm and entered the first level, everything was exactly as Feng Ling predicted.

Although the beasts on the first floor of the Heavenly Sacrifice Tower weren't even at the second floor, they were still much stronger than the first time Feng Ling had come in. Although the beasts on the first floor of the Heavenly Sacrifice Tower weren't at the second floor, they were still much stronger than the first time Feng Ling'er came in.

There were too many berserk beasts outside, and all four of them were level three experts. Even if Yun Tu went back to lead the team, other than Yun Tu, the rest of the people from the Dark Night Guild were all level two advanced beasts, so it was unknown whether or not the team Yun Tu brought could kill their way to the peak of the Skysplit Tower to meet up with them.

He could only rely on himself!

As for the Cloud Diagram that he had reincarnated into, he could roughly guess what kind of new changes would happen to Feng Ling, Wang Ze, and the others after entering the Heavenly Sacrifice Tower's secret realm.

The last time they had entered the secret realm, over two months had passed. As the humans' overall strength had increased, not only had the fierce beasts of the Heavenly Sacrifice Tower's secret realm leveled up, the other three secret realms' fierce beasts had also levelled up. These berserk beasts were no longer secrets in Jiangnan City, they had just been hiding from the famine in the Ox Back Ridge, and so they did not know about it.

The secret realm had always been a mystery. The last time a Level 4 King Kong Wolf appeared in the Heavenly Sacrifice Tower, it was a special case. According to common sense, the First Clear for the Secret Realm of the Serene Cloud Palace only showed Level 3 Centaur Beasts. Afterwards, Yun Tu speculated that all of this might have something to do with the Falling Ice King and the others entering the secret realm. After all, they were a different species and had advanced to rank 3 before the humans.

Now the problem was, since an anomaly had appeared during the first mission of the Heavenly Sacrifice Tower, then what would happen next?

But no matter what, without the help of the other teams, could Feng Ling, Wang Ze, and the rest of the four bite the Quest BOSS down? Yun Tu felt that this was too difficult!

Letting them enter the Heavenly Sacrifice Tower was forced by the circumstances. They didn't think too much about it at that time, and after killing the Bone Devil and leaving their predicament, Yun Tu didn't dare to stop. He quickly led Black Back to the south region!
