Su Yifei wanted to get rid of the female mutant orc who was suspected to be Su Rusha, no matter if there was any inside story in this, as long as he got rid of the completely burned and nothing left, there would be no trouble.

But it's not that easy, I don't know if the female mutant orc opened the spiritual intelligence, or if the main messenger behind the scenes issued an order. But when Su Yifei is in Sujia Fort, the mutant orcs will not appear around.

The mutant orcs that appeared in other areas of the Cloud Country far away from Sujiabao were also quick to decide, and Su Yifei couldn't even see the shadow of the female mutant orcs.

The situation was stalemate for a while, and in order to protect themselves, the people of the entire Xuanhuang Continent were huddled in the city.

Although this disaster has only been a few months ago, the humans of the entire Xuanhuang Continent have lost at least one-fifth, which is very tragic, but under the counterattack of the humans, the damage of the mutant orcs is even heavier.

There are many people in the city, and now the mutant orcs who are gradually decreasing in number cannot be defeated in a short time, and after a long time, the powerful reinforcements of the human race will arrive.

Although the strength of the remaining mutant orcs has been promoted very quickly, the human beings have crystal nuclei in their hands that can be used to quickly improve their cultivation, and in addition, they often fight to the death with the mutant orcs, and the overall strength of human cultivators is also rapidly improving.

A few months after entering the stalemate, a large number of Venerable Beings appeared in the Xuanhuang Continent, attracting some cultivation mad demons on the Shangqing Continent, who flocked to the Xuanhuang Continent through the teleportation channel and sent more troops to the Xuanhuang Continent.

Although these cultivators on the Shangqing Continent are not very high, not many of them have reached the Venerable level. However, they had extremely rich experience in fighting mutant orcs, coupled with high-tech attack weapons that were not available on the Xuanhuang Continent, so the situation began to tilt in favor of humans.

In the third year after the sudden appearance of the mutant orcs, the humans killed the vast majority of the mutant orcs, and the remaining mutant orcs all retreated back into the underground world.

Before Su Ruoji and Ye Chongshan did not ascend, they also suspected that there were likely mutant orcs underground, and even the two of them personally led people to investigate, but later they didn't find any clues before letting go.

At that time, it was just a speculation by the two of them, although the actions of the Zijin Sage and the Ziao Sage were known to many high-level cultivators, but because the two Sages did not recruit the cultivators to act together, except for the descendants of the two of them, there were no other forces involved in the matter.

In the Xuanhuang Continent, the Zijin Sage with the strongest spiritual power is very prestigious, and since she can't find out anything, the others don't have to think about it. In addition, there had been no trace of mutant orcs in the Xuanhuang Continent for hundreds of years, so everyone left this matter behind.

As a result, I didn't expect that after only ten years of ascension in Zijin Sage, those mutant orcs under the ground suddenly appeared to attack humans.

After suffering such a tragic attack, no one dared to neglect to leave such a hidden danger, let alone the cultivators of the Xuanhuang Continent, even the cultivators of the Shangqing Continent were all in favor of killing them all to get rid of the trouble.

The faster the time for the great counterattack, the better, because with the experience of the successful ascension of the Ziao Sage and the Zijin Sage, coupled with the attack of the mutant orcs, the human race has also obtained a large number of crystal nuclei to help cultivation, and no one can say for sure when the three Great Sages who have now cultivated to the late stage of the Great Perfection of the Holy Level will ascend.

Even if only one saint ascends, it will greatly weaken the total strength of the human race, you must know that those mutant orcs who retreat back into the ground are almost all supreme and saint-level cultivators, and without a saint-level late-stage saint to lead the team into the underground world, they are afraid that there is a great possibility that the entire army will be wiped out.

After making sure that all the living mutant orcs had retreated underground. The great power of the entire Xuanhuang Continent held a general meeting and decided to organize people to counterattack from each known cave in the Xuanhuang Continent.

The body of the mutant orcs is already taller than that of humans, so even if the underground passage is not spacious, it is very loose for humans to walk in it. The darkness in the underground passage is normal, and everyone has something that can be illuminated, but what makes people uncomfortable is the smell of the tunnel.

If it weren't for the action of the cultivators, the worst cultivation was also at the Venerable level, and his physical fitness was extremely fierce, and he was so smoked by the smell left by the mutant orcs that he was about to vomit to death.

Su Yifei, as always, went out with his second son Su Yu. The eldest son, Su Xin, is the head of the Su family and the second master of the Su family, and has always been in the base camp.

Su Yu is a mid-level saint, and although his martial power value is the last of the top ten masters in the Xuanhuang Continent, it is enough to take on any heavy responsibility.

Su Yifei led the cultivators sent by the large and small forces near Sujiabao to enter through the cave in the forest outside Fande City. And Su Yu is the former peak master of Scorpio Peak, such as the Great Elder of Mormon today, so he naturally returned to Heaven Mormon to lead the team.

Humans are ignorant of the situation in the underworld, and they can't guess which force will encounter the biggest boss, and they don't know if there is a way to communicate underground, or if they can ask for help from their accomplices. Only be prepared to fight alone, and try to balance the strength of each team, so as to have the power to escape from the battle when you meet the big boss.

Before entering the underground, everyone was ready to be attacked by various superior attacks by mutant orcs in the tunnel, but Su Yifei and his party only encountered some sporadic attacks on the third day of entering the underground.

The cultivation of these mutant orcs who attacked them was not high, and the highest was only the Venerable level, and none of them were at the Sage level.

"Zhongge Sage, these mutant orcs seem to have a purpose. During the break, the young Venerable from the Tan family came to Su Yifei's side and whispered.

More than a hundred years ago, the Tan family was suppressed for betraying the Zijin Sage. Later, the true identity of Zijin Sage's mother was exposed, and the Tan family's betrayal of Zijin Sage was suppressed to the point that they no longer had the power to rise, and Zijin Sage thanked the Tan family for saving his mother and adoptive mother, and the Tan family was able to rely on the Su family again.

Because of this, the more outstanding Venerable of the younger generation of the Tan family has been somewhat looked at differently by Su Yifei, and he can say a word or two in front of him as a junior.

Su Yifei glanced approvingly at the Venerable Tan family who was speaking, and said, "These mutant orcs are holding us back for a purpose. ”

After perceiving the purpose of the mutant orcs, Su Yifei and his party changed their previous cautious attitude and accelerated the pace of progress. After they walked for a day, the resistance they encountered along the way was still a high-level mutant orc, which confirmed Su Yifei's conjecture more and more.

On the fifth day of entering the underground, the unchanging narrow tunnels began to widen, and of course, the smell peculiar to mutant orcs was extremely strong.

And under the light of the light, the white bones are often seen in the cave. Some of these bones are beasts, but many more are human bones. The further they went, the more skeletons they saw, and at a glance they knew it wasn't recent.

This situation can't help but make people feel depressed, no wonder since ancient times, there have often been human disappearances on the Xuanhuang Continent, but no one has ever discovered the truth.

On the eleventh day, as the people walked, suddenly there was a light on the other side of the tunnel......
