After Ling Crab finished picking the Red Snail Sky Crystal Umbrella from the tree trunk, he took Ling Feng and the others and continued walking upstream of the river.

As Ling Feng and the others continued to approach the upstream, the power of rules acting on them gradually became stronger, and Ling Feng felt that the true energy in their bodies was imprisoned.

Ling Feng tried the power of blood and found that the power of blood was not suppressed, and the same was true of the power of soul.

This made both Ling Feng and Cang Yu sigh in relief, because the situation was not very bad.

"Boom!"

Suddenly there was a fierce fighting sound from ahead.

Ling Feng and Cang Yu immediately accelerated forward.

After a while, they saw two behemoths fighting on a river beach.

"This is a saber-toothed porcupine and a red alligator!"

The spirit crab immediately communicated with Ling Feng and the others.

The sharp spines on the saber-toothed porcupine emitted a dazzling golden light, and the surrounding energy quickly gathered towards it.

"roar!"

The saber-toothed porcupine roared, then shook its body violently, and the spikes on its body immediately turned into streaks of golden light rising into the sky.

After these golden lights flew thousands of meters into the sky, they suddenly turned around, fell from the sky, and shot down towards the red alligator.

The red alligator also felt a huge threat. It immediately turned around and tried to escape back into the river.

But those golden spikes shot by the saber-toothed porcupine were extremely fast and hit its body instantly.

"Clang, clang, clang..." Because the golden spikes were too fast and had a strong impact, after they were shot on the scales of the red alligator, the powerful penetration caused cracks to appear on the red scales.

.

"What a strong defense!"

Ling Feng and Cang Yu were shocked when they saw that the scales of the Red Alligator could block the spikes of the saber-toothed porcupine.

Whether it is the red lin alligator or the saber-toothed porcupine, they all have the strength of a mighty king.

Neither Ling Feng nor Cang Yu expected that the creatures they saw here were so powerful.

Although the red alligator's scale defense was powerful, it was unable to block all the spikes of the saber-toothed porcupine. In the end, its body was penetrated by more than a dozen spikes, and it immediately fled back into the river.

.

The red alligator roared and then went to the river to drink water.

Although the saber-toothed porcupine is an omnivorous creature, it does not want to eat the red alligator.

The reason why it fought the red alligator was because it was attacked by the red alligator when it was drinking water, which completely angered it.

Now that the red alligator was injured by it, it can finally drink water with confidence.

"The creatures here are so powerful!"

Cang Yu spoke to Ling Feng in her heart.

"Um!"

Ling Feng nodded slightly. Now he seemed to understand why Elder Hua Yun, a powerful king, asked for help.

He now felt a strong sense of crisis.

In this place, the true energy in their bodies is suppressed, and the creatures here are extremely powerful. Various signs indicate that this place is not simple.

Ling Feng avoided the saber-toothed porcupine because they had just arrived and didn't know much about this place. They didn't even notice a single person.

So they don't want to conflict with this Jianchi porcupine now.

Lingfeng opened his mouth and asked Ling Crab: "Ling Crab, can you take me and Cang Yu into the space inside your body now?"

Ling Feng felt that under the current situation, it would be safer for him and Cang Yu to hide inside the spirit crab.

"I'll give it a try!"

The spirit crab immediately spit out bubbles and enveloped Ling Feng and Cang Yu.

But when the spirit crab was about to take Ling Feng and Cang Yu into its body, it found that it could not take Ling Feng and Cang Yu inside at all.

It opened its mouth and said to Ling Feng: "No, I can't open the space in my body here at all!"

Ling Feng frowned slightly and said, "Now it seems that we can only rely on ourselves!"

Cang Yu nodded to Ling Feng.

Ling Feng and Cang Yu kept walking up the river.

But after walking for a while, Ling Feng and the others discovered a strange phenomenon. The slope of the river was not gradually going up, but downward.

The terrain in front of them was downhill, but the river flowed from low to high.

Where they are standing now is a watershed.

The river in front of them continued to flow upward from the lower place. After crossing the hurdle under their feet, it flowed downwards.

This was the first time for Ling Feng and the others to see such a strange phenomenon.

"How strange!"

The spirit crab landed by the river and soaked its body in the river water. It kept spitting bubbles and felt the specialness of the river water.

There is nothing special about this river except that it is rich in spiritual energy.

"What do we do?"

Cang Yu asked Ling Feng. At this moment, she felt a little depressed, because they had been here for more than three hours, but they didn't even see a single person, and all kinds of strange phenomena appeared in front of them one after another.

"Huh..." At this moment, a huge creature flew over their heads, leaving a huge shadow on the ground.

Ling Feng looked up and saw that flying through the sky was a pterosaur.

He found that there seemed to be a person standing on top of the pterosaur.

"Someone!"

Ling Feng's eyes narrowed, this was the first person they saw after entering this place.

The pterosaur was so fast that it almost disappeared from Ling Feng's sight in the blink of an eye.

"I feel relieved if there are people there! There should be human cultivators in front of us, let's go over and have a look!"

After Ling Feng finished speaking, he took Cang Yu and walked downwards. Because they were not familiar with the environment here, Ling Feng and Cang Yu did not dare to fly.

Although their true energy has been suppressed, their bloodline power can still be used. Using the bloodline power, they can also fly in the air here.

But Ling Feng and Cang Yu didn't want to do this.

After Ling Feng and Cang Yu walked forward for a while, they discovered that another special power of rules seemed to have appeared.

Ling Feng frowned slightly. He circulated the power of blood and found that the power of blood was also imprisoned.

"It seems the front is more dangerous than we thought!"

Ling Feng said to Cang Yu in his heart.

"Um!"

Cangyu nodded, and her expression became serious.

Ling Feng took Cang Yu and walked downward along the backward river in front of him.

An hour later, they saw the ruins of an ancient city ahead.

All the ruins here are ruins. Although wind and rain have left traces of time on them, Ling Feng and Cangyu cannot see any moss or vegetation on these ruins.

The ruins of the ancient city in front of me are lifeless.

"It's so strange that there are no signs of life in this city!"

Lingfeng kept observing the environment in front of him.

Around the ruins of the ancient city, the vegetation is very lush, and there are even towering trees that are tens of meters thick and hundreds of meters high.

If you look down from the air, this ancient city looks like a scar in a primeval forest.
