"Um!"

Ling Feng nodded slightly, he knew that there was too much energy contained in the universe.

The technique he is practicing now is definitely not able to absorb all the energy in the universe.

Just like a mortal, after eating a kind of food, he can only absorb part of the nutrients in the food, and there are some substances that mortals cannot absorb.

These substances, which mortals cannot absorb, are excreted from the body.

Even though Ling Feng's Hunyuan Heavenly Book is already very powerful, Lingfeng knows that the Hunyuan Heavenly Book can only absorb a small part of the energy in the universe.

There is still a lot of special energy in the universe that he cannot absorb yet.

If he could absorb more types of energy, it would definitely be of great help to him.

Lingfeng opened his mouth and said to the spirit crab: "Let's find some animals to study first, because we are also one of the animals, and our body structures are relatively similar!"

"good!"

The spirit crab responded, then went into the mountains with Lingfeng and began to capture animals in the forest.

At this moment, the flow rate of time in the forest is more than 30 million times that of the outside world.

Under this terrifying speed of time, even the Lord does not dare to stay for too long.

Soon, Lingfeng caught a rabbit.

This rabbit is not very strong. Although they can live here, in the eyes of Ling Feng and Ling Crab, this rabbit is just like an ordinary rabbit.

Originally, Ling Feng thought that this rabbit's physical fitness was very strong, but when Ling Feng studied this rabbit, he found that this rabbit's physical fitness was not very strong.

"how so?"

After seeing the rabbit's body structure, Ling Feng couldn't help but frown.

The spirit crab looked at Ling Feng and said, "Ling Feng, don't be surprised. This is normal. For example, a fish that lives thousands of meters under the sea can withstand the terrifying water pressure thousands of meters deep. It's not because of their

Their bodies are strong because of their special body structure!"

"Um!"

Ling Feng nodded slightly. In the mortal world, those fish living thousands of meters deep on the seabed are not made of steel.

The spirit crab said: "We now need to focus on the special body structure of these animals to study why they can survive here and why they can absorb special energy from the outside world..."

Ling Crab slowly explained to Ling Feng.

In terms of fighting, the spirit crab cannot compare to Ling Feng, but in terms of research, this is the spirit crab's specialty.

Later, Ling Feng and Ling Crab began to study in the forest.

Although in such an environment, Lingfeng's body consumes energy very quickly.

However, in such an environment, Ling Feng could still continuously absorb enough energy from the outside world to replenish it.

Three days later, Ling Feng discovered an inner elixir inside a black tiger.

The existence of this inner elixir allows the black tiger to absorb energy from the outside world faster, which also makes the black tiger stronger.

In terms of attack power, the attack power of this black tiger is already comparable to that of a human cultivator at the Golden Core Stage.

Although the attack strength was only at the Golden Core stage, in this environment, even the human lord would not dare to attack this black tiger rashly.

Because in such an environment, even if you stand still, the energy in the human body is already consumed very quickly. If you continue to fight, the energy in the human body will be consumed even faster.

This is like a person who dives underwater. Although he does nothing and holds his breath for a longer time, the oxygen in his body will be consumed faster if he does strenuous exercise underwater.

Ling Feng knocked Black Tiger unconscious.

But after Lingfeng knocked Black Tiger unconscious, he found that Black Tiger could still absorb energy from the outside world, but the speed of absorbing energy had slowed down.

However, Ling Feng discovered that the energy in these animals was very different from the energy in the flesh and blood life outside.

Ling Feng and Ling Crab continued to study these black tigers.

Three days later.

The spirit crab opened his mouth and said to Ling Feng: "Ling Feng, the reason why these animals can absorb energy from the outside world is because they have a special mark in their bodies. This mark should have evolved over the long years.

!”

"But, how can we absorb the special energy in the surrounding space like them?"

Ling Feng frowned and pondered in his heart.

The spirit crab said: "Since you can't become like them in a short time, you can try to take the plants here, or even eat the flesh and blood of these animals, so that the energy in these animals and plants can slowly change your physique.

, you may be able to absorb the special energy around you!"

"good!"

Ling Feng nodded slightly, and then he directly put some blood on Black Tiger's body.

The blood of these black tigers is grey-brown.

Lingfeng drank Black Tiger's blood directly.

When Lingfeng drank the blood of the black tiger, he immediately felt that what he had swallowed was not blood, but a mouthful of iron sand.

The iron sand rubbed against his throat, causing bursts of pain.

"Chichi..."

A mysterious energy emitted from Black Tiger's blood, and this mysterious energy surged through Ling Feng's body.

"ah!"

Ling Feng immediately let out a scream and rolled on the ground.

"Lingfeng, how are you?"

Seeing Ling Feng's painful look, the spirit crab also panicked a little.

Ling Feng responded in his heart: "I'm fine, I can still bear it!"

After saying that, Ling Feng also stopped screaming. At this moment, he wanted to run the Hunyuan Heavenly Book to refine the energy in his body, but the effect was not very good.

It seems that the Hunyuan Heavenly Book cannot refine this special energy in the body at all.

Looking inside, Ling Feng saw that the energy was gray-brown.

This mysterious energy rushed around in Ling Feng's body, and finally poured into Ling Feng's Dantian.

At this moment, a terrifying devouring force came out of Hongmeng Dantian.

"Chichi!"

The mysterious energy in Lingfeng's dantian was instantly sucked into Hongmeng's dantian.

After feeling this change, Ling Feng's consciousness immediately entered Hongmeng Dantian.

When he saw Hongmeng Yuanying, he opened his mouth and ate the mysterious energy.

After eating the mysterious energy, some gray-brown runes appeared on the surface of Hongmeng Yuanying's body, but those runes turned purple in less than a moment.

After Hongmeng Yuanying ate the gray-brown energy, he seemed to be still unsatisfied. He licked his mouth, and then an even more powerful devouring force burst out in Ling Feng's body.

"Buzz!"

Lingfeng felt the powerful power emerging from Hongmeng's dantian and taking control of his body.

Ling Feng couldn't control his body at the moment.
