At this time, a head with only a pair of scarlet eyes exposed slowly poked out from the mud. The scarlet eyes stared at Xu Feng's back. Seeing Xu Feng turn in another direction and continue to explore forward, the huge head slowly sank into the mud again, leaving only ripples in the turbid mud water. Xu Feng seemed to have sensed something and turned his head to look at the black swamp. There was nothing else except the black mud with bubbles and the ripples in the mud water. The turbid mud could even block Xu Feng's spiritual exploration, so he had no idea what kind of terrible monster was hidden in the swamp!

All the Black Lotus clones disappeared and entered a cooling period. They could only be summoned again after half an hour. This time, Xu Feng directly summoned a third-level skeleton soldier from the secret realm and controlled it to continue exploring the way for him.

In Xu Feng's secret realm, there is a Bone Temple, which is a war building that can produce a batch of undead creatures every month. However, Xu Feng needs to spend gold to summon them. If he does not summon them, the produced undead creatures will be stored in the temple. As long as Xu Feng needs it and has enough resources, he can summon an army of undead at once.

However, the level of this undead army was too low, not even at the level of a wandering immortal, and could provide little help to Xu Feng. Therefore, for a long time, Xu Feng had forgotten about the Bone Temple and was unwilling to spend resources to summon these low-level undead soldiers.

But now Xu Feng needs cannon fodder to explore the way, and these low-level undead soldiers in the Temple of Bones come in handy.

However, what surprised Xu Feng was that this swamp did not seem to repel undead creatures. Xu Feng saw with his own eyes that the skeleton soldier who was exploring the way stepped into the swamp and even fell down, with half of his body sunk into the swamp. In theory, he should have been swallowed by the swamp, but this skeleton soldier actually relied on his meager strength to crawl out of the swamp in a slightly embarrassed manner...

"The poisonous swamp doesn't repel or devour undead creatures?" Xu Feng showed a look of surprise on his face, and couldn't help but think to himself, "No wonder that disciple of the Netherworld Pavilion named Ouyang Ling lured the hunting team to this area. This place is like a paradise for undead creatures!"

The two most terrifying things about the Poisonous Swamp are: one is the miasma formed by the corrupt and highly toxic air, and the other is the swamp abyss that seems to have life and self-awareness. The cultivators still have a solution to the miasma formed by the highly toxic air, and the detoxification beads sold by Qian Dafu of the Baimai Sect are one of them. However, the swamp abyss that seems to have life and self-awareness is the nightmare of every creature that enters the Poisonous Swamp. Sometimes, even a shallow ditch on the surface can cause the death of a king or even an emperor-level powerhouse. The danger is self-evident!

However, for the undead creatures, any poison will not cause any harm to them. The undead have the racial talent of being immune to poisons, and the swamp abyss seems to ignore the undead creatures. Even if you go deep into it, it will not swallow them. This makes it possible for the undead creatures to walk freely in the poisonous swamp...

After discovering this characteristic, Xu Feng immediately summoned a large number of undead warriors and ordered them to explore in all directions. Thousands of undead warriors in the poisonous swamp were like salt sprinkled in the sea, inconspicuous, but for Xu Feng, they were excellent pathfinders. The efficiency of finding a safe road was increased hundreds and thousands of times.

In just two incense sticks of time, Xu Feng, with the help of thousands of undead creatures, discovered a safe path leading to the innate formation in the center of the swamp, which made Xu Feng feel happy.

Although the Undead Warriors are not restricted by the terrain in the Poisonous Swamp, they will still be killed by other monks if they encounter them. However, the occasional loss of three or five is normal, but the loss of dozens of them at once is obviously a bit abnormal.

The next moment, a terrifying monster leaped up from the horizon ahead. It looked like a huge whale shark leaping up from the sea and then falling heavily into the swamp.

With just a glance, Xu Feng had already detected the properties of this horrifying monster; "Poisonous Whale Shark, peak emperor-level strength, undead creature, lord-level BOSS template, able to swim unhindered in the poisonous swamp..." The light screen that appeared in front of Xu Feng detailed the horror of the poisonous whale shark; "This undead creature actually controls more than 1,300 laws of power?" Xu Feng couldn't help but show a look of surprise on his face. Although so many laws of power were all about poison and netherworld attributes, being able to control so many laws of power was already more than many supreme elders of the Baimai Xianzong.

At this time, Xu Feng also discovered that the dozens of undead creatures before were all killed by this huge and terrifying monster. Maybe it was not intentional, but just a leap and fall was not something that the undead creatures could withstand...

This poisonous whale shark blocked Xu Feng's way to the Netherworld Array, and the previous movement also attracted the attention of many cultivators around. Xu Feng could already sense that many cultivators were moving quickly in that direction; after hesitating for a moment, Xu Feng also quickly rushed in that direction. No matter what, he was unwilling to let others get the stone lamp in the Netherworld Array.

Because they had discussed the route in advance, Xu Feng was the first to arrive at the swamp where the poisonous whale sharks appeared;

This swamp was muddy and turbid, and its area was extremely vast and boundless, giving people a feeling of standing by the sea. At this moment, Xu Feng suddenly felt the hairs on the back of his neck stand up, obviously an extremely dangerous creature was staring at him; "Could it be that poisonous whale shark?" Xu Feng thought to himself.

The next moment, pairs of scarlet eyes emerged from the muddy sea in front of him. In the miasma-filled muddy sea, they were like pairs of red lanterns, staring at Xu Feng as if they were staring at prey.
