Chapter 131: Mutation

"Ah!"

Before Lin Chen and his four companions could wait too long, another demon beast roared and rushed into the black fog without hesitation.

"Hmm?"

Lin Chen narrowed his eyes and looked at the demon beast without expression. The demon beast was a low-level fifth-level giant python, named Giant Spirit Mang. It was extremely large and was a very powerful one among the low-level fifth-level demon beasts.

Seeing the giant spirit mang rushing into the black fog, the many demon beasts around the black fog suddenly became more anxious. They roared one by one, wanting to follow the giant spirit mang into the black fog, but they seemed to be a little afraid of the black fog and did not dare to move forward.

"Roar."

Just then, a top-level fourth-level demon beast roared, jumped up, and jumped into the black fog in front of it. As this top-level fourth-level demon beast entered, the demon beasts around the black fog suddenly roared one by one, with crazy expressions, and actually followed the demon beast and jumped into the black fog.

In an instant, except for more than ten monsters that were afraid of the black fog and did not dare to move forward, all the other monsters rushed into the black fog.

"What's going on?" Chen Feng looked at the monsters that jumped into the black fog with some horror. What on earth was in the black fog that made these monsters so crazy?

Lin Chen looked solemn and stared at the black fog without blinking. Lin Chen's soul power was strong and his senses were extremely sharp, but even so, he could only vaguely see the monsters in the black fog. As for Ao Xin, Yang Yifan and Chen Feng Sanran, they could only see a vague black shadow.

"Ah~"

"Roar..."

As these monsters jumped into the black fog, in the blink of an eye, the roars of many monsters came from inside. Lin Chen could vaguely see that the monsters were rolling wildly in the black fog, as if they were being bombarded very strongly and in great pain.

Even the giant spirit that entered the black fog first was rolling on the ground, stirring the black fog randomly, which looked extremely strange.

"What on earth is that black fog? Even a level 5 monster can't stand it after entering it." Ao Xin looked solemn.

A powerful level 5 low-level monster is almost equivalent to a warrior in the early stage of the True Dao Realm, but even a warrior in the early stage of the True Dao Realm couldn't resist the black fog, so the latter was a little too terrifying.

No one spoke, and they all stared at the rolling black fog without blinking. The black fog was stirred by many monsters, but it didn't emit a single bit. It seemed that there was a barrier covering them all and couldn't emit it.

Not long after, the frequency of the black fog being stirred was lowered, and the roars of many monsters in the black fog became lower and lower at this moment. In the end, all the monsters fell to the ground and died.

"All dead?" Chen Feng's face was gloomy and ugly in an instant. The aggressiveness of the black fog was really terrifying. Hundreds of level 5 low-level monsters died in just a dozen breaths.

But at this moment, Lin Chen narrowed his eyes suddenly, and saw a dark shadow moving in the black fog. Perhaps the shadow was too deep into the black fog, and Lin Chen could not see what kind of monster it was.

"There is a monster that is not dead."

Lin Chen spoke slowly.

"What?" Ao Xin was shocked. So many monsters were dead, and there were still some that were not dead? But what surprised Ao Xin even more was that Lin Chen could find the monsters that were not dead, that is, what Lin Chen could see was much more detailed and clear than what the three of them saw.

Yang Yifan narrowed his eyes and looked at Lin Chen deeply, his face did not change at all.

"Lin Chen, are you sure you saw a monster that was not dead?" Ao Xin asked again with a serious look.

Lin Chen nodded and said, "There is indeed a black shadow, but the monster is too deep into the black fog, and I can't see what kind of monster it is."

After listening to Lin Chen's words, Ao Xin pondered. What kind of monster could resist the attack of the black fog and go deep into it? However, it must have been seriously injured when the monster went deep into the black fog.

The most important thing is that since the monster has entered the black fog, the code in the black fog should also be solved.

Ao Xin pondered for a moment and whispered: "Let's wait here for a few days to see if the monster will come out."

The things in the black fog actually made so many monsters covet the things in it, so what exactly is inside?

Although they were very curious, the four of them did not dare to enter the black fog rashly. After all, even the fifth-level monster died in the black fog, so if the four Tiangang Realm warriors entered, they would probably die.

Therefore, the four of them could only stay where they were and wait for the monster to come out of the black fog. Perhaps the day when the monster comes out is the day when the secret of the black fog will be solved.

However, Lin Chen and the other four did not know when the monster would come out, but this was already a helpless solution, and they could only wait here.

Time passed little by little, and Lin Chen and the other three stayed on the tree, taking turns to guard the black fog. In the blink of an eye, more than ten days passed. For more than ten days, there was no movement in the black fog. During this period, dozens of level five monsters came from other places in the Molian Mountains. However, most of these monsters had already rushed into the black fog and died in it. At this moment, there were only more than ten low-level level five monsters left outside the black fog.

Even though there were only a dozen level 5 low-level monsters, Lin Chen and his four companions were still cautious, fearing that they would be discovered by these dozen level 5 low-level monsters. Fortunately, these monsters focused all their attention on the black fog, and Lin Chen and his four companions deliberately concealed their auras. In the past ten days, these dozen monsters did not notice that there were four human warriors hiding behind them.

In the morning, it was Lin Chen and Ao Xin's turn to observe the black fog. Yang Yifan and Chen Feng stayed on the big tree to rest.

Lin Chen and Ao Xin chatted while observing the black fog. The many level 5 low-level monsters around the black fog were still anxious and wanted to rush into the black fog, but they were afraid to move forward, which was extremely contradictory.

"Sisi!"

At this moment, a shocking momentum suddenly rose up in the black fog. This momentum was extremely huge and instantly covered the entire valley. The many monsters outside the black fog felt this huge aura, and they all crawled on the ground one by one, looking extremely terrified.

"Hmm?"

Lin Chen and Ao Xin's faces also changed, their eyes fixed on the black fog not far in front of them.

Yang Yifan and Chen Feng also opened their eyes in an instant, looking at the black fog with a serious look.

"What is it?"

"Could it be the monster that entered the black fog before and didn't die?"

The four looked at each other and felt incredible. If it was really the breath emitted by the monster that entered before, the change before and after was a bit too big. When it entered the black fog, it was only a low-level monster of level 5, and the breath it exuded was at most a little stronger than other low-level monsters of level 5, not as strong as it is now, causing many level 5 monsters to crawl on the ground in fear.

Lin Chen's face was solemn, looking at the black fog in front of him, but at the same time, he also suppressed the breath on his body to the lowest.

"Sisi"

Before Lin Chen and the other four waited too long, a giant monster with a burly figure and a length of dozens of feet suddenly rushed out of the black fog.

As it appeared, all the other monsters around it crawled on the ground and dared not move.

Seeing this monster appear, Lin Chen, Ao Xin and the other two were all stunned.

"Giant Spirit Mang!"

The monster that rushed out of the black fog was the Giant Spirit Mang! When many monsters entered the black fog, the Giant Spirit Mang was the first to enter, but at that time, the Giant Spirit Mang was only a low-level monster of level 5, and now...

"How could this happen!" Yang Yifan's face changed, and he said in disbelief: "When the Giant Spirit Mang entered, it was only a low-level monster of level 5, and now it is already a top-level monster of level 5..."

Top-level monster of level 5!

It has been raised by two realms!

When the monster enters the fog and reappears, its cultivation strength will increase greatly. So, what is in the black fog?

Lin Chen and the other four felt incredible, but more importantly, if there are more monsters that continue to enter the black fog and do not die, it will probably not take long before a large number of high-level monsters will appear in the entire Molian Mountains. The consequences will be disastrous.

The giant spirit beast's huge body was supported on the ground, its snake core was constantly swallowing and spitting out, and its eyes were cold and cruel, scanning the other monsters crawling around with the attitude of a superior looking at the inferior.

A level 5 low-level monster is equivalent to a warrior in the early stage of the True Dao Realm, while a level 5 top-level monster is equivalent to a warrior in the late stage of the True Dao Realm. It is extremely powerful, and a Tiangang Realm warrior can kill it with a casual blow.

When the beast tide occurred in Jinyang City, Lin Chen saw with his own eyes that several True Dao Realm masters besieged a level 6 low-level monster. Although this giant spirit beast is not a level 6 low-level monster, it is also a level 5 top-level, the overlord among the level 5 monsters, and it is definitely not easy to mess with.

Seeing the giant spirit beast swallowing and spitting out the snake core, Lin Chen's heart suddenly tightened, as if there was a heavy hammer, hammering hard on his heart, making it difficult for him to breathe.

Lin Chen felt uneasy in his heart. Suddenly, the giant spirit beast turned his head, and his eyes were cold and cruel, just looking in the direction of Lin Chen and the other four. This giant spirit beast is now a top-level fifth-level monster. Whether in terms of cultivation strength or perception, it is not comparable to the low-level fifth-level monster beasts. As soon as it appeared, it immediately discovered Lin Chen and his four companions.

"Run!"

Lin Chen's heart tightened. He growled and turned around and ran towards the Tianji Sect without hesitation.

What a joke. If Lin Chen stayed to deal with this giant spirit beast, it would be like an egg hitting a stone. He would definitely die. What's more, as the giant spirit beast discovered Lin Chen and his four companions, other fifth-level monster beasts outside the black fog also discovered them.

Once surrounded by so many fifth-level monster beasts, even if Lin Chen and his four companions could avoid the giant spirit beast, they would die in the siege of many fifth-level monster beasts.

"Run!"

"Go!"

Ao Xin, Yang Yifan and Chen Feng also changed their faces. They all growled and then tried their best to perform footwork and quickly went towards the Tianji Sect.

The four of them had all cultivated the skills to run fast, and they had all reached the state of great success. They were extremely fast. In the blink of an eye, the four of them had already run thousands of meters.

But at this moment, the top-level Level 5 giant spirit moved. Its huge body suddenly shrank forward, and the whole body instantly moved thousands of meters, closing the distance with Lin Chen and the other four at an extremely fast speed.

At the same time, more than a dozen low-level Level 5 monsters outside the black fog also roared and chased after Lin Chen and the other four.
