The swamp dragon was fighting against the swamp five-headed snake and the swamp three-headed dragon crocodile. He was seriously injured and his spiritual sense had been weakened a lot. Then Shu Feng's attack made it and one eye was smashed.

The swamp dragon's eyes broke, and he became even more cruel. He struggled wildly. He tore his claws hard and tore off one of the heads of the swamp five-headed snakes.

The swamp five-headed snake screamed and tangled even tighter.

The three-headed dragon crocodile took the opportunity to step forward, and the three heads bit wildly, and bit one of the claws of the dragon. The three heads pulled hard, biting the claws so hard that they were bloody and bloody, and the bones were cracked.

The remaining claws of the swamp dragon were blasted out with a fierce claw, containing black claws. They hit one of the heads of the swamp three-headed dragon crocodile with one blow, and penetrated one of the heads of the swamp three-headed dragon crocodile with one blow.

One blow smashed one of the three-headed dragon crocodiles in the swamp, and the aura of the swamp dragon suddenly became much weaker.

A afterimage flashed, and the steel beast jumped up from the back of a swamp three-headed snake. In the air, it suddenly changed into a third form, with a golden light blooming all over its body. It slashed wildly with an iron sickle in its hand, turning into a cold light that seemed to tear apart the sky and slashed hard between the neck of the swamp dragon.

Countless blood sputtered, and the head of the swamp dragon was blown up halfway by the steel beast, and a large piece of blood sputtered out.

The three-headed dragon crocodile swamp took the opportunity to pounce, and the two heads bit wildly, biting the wound of the swamp dragon hard, and tore it wildly, tearing it apart, and tearing it apart.

Countless blood ejected from the wound of the swamp dragon. No matter how strong its recovery power was, it could not resist such a terrifying bleeding.

The three remaining five-headed snakes in the swamp, with sharp teeth, bite them wildly, and bite them on the wound of the swamp dragon. They tore them hard, tearing them a large piece of flesh and blood again, and countless blood burst out.

The swamp dragon was subjected to such a fatal attack one after another, and its power began to flow away wildly with the blood in its body. It was hit hard, struggled for a while, and then the swamp three-headed swamp dragon crocodile bit off its neck and lost its breath.

"Advanced soul 1, spiritual power 2 million!"

A prompt sounded at once.

Shu Feng looked at the 40-meter-long corpse of the swamp dragon and said silently in his heart: "It's indeed a swamp dragon of the Spirit Lord level! It's really cruel!"

"In this swamp dragon swamp, there are indeed a crouching tiger and hidden dragon, hiding countless cruel swamp monsters. One swamp three dragon crocodile is not enough to dominate the swamp dragon swamp."

Shu Feng looked at the scarred swamp three-headed dragon crocodile and the swamp five-headed snake whose head was torn off. He had a deep understanding of the dangers of the swamp dragon swamp and understood why this place was not explored.

If a strong man at the Spirit Saint level has not been specially practiced by swamp magic, he will be unable to move in this swamp dragon swamp. Even if those strong man at the Spirit Saint level can fly, it will be very dangerous to encounter monsters like swamp dragon with the ability to forbidden air domain.

The forbidden air domain of a swamp dragon naturally cannot help but get a strong man from the Spiritual Saint Realm, but once the forbidden air domain of a swamp dragon is superimposed, even the strong man from the Spiritual Saint Realm will be trapped.

In addition, there is indeed no treasure in the swamp dragon swamp that makes the powerful people in the Spirit Holy Realm crazy, so this place has become a useless place.

"I don't know if there are any divine remains in the corpse of the demigod-level monster."

Shu Feng looked at the skeleton of the huge Demigod Swamp Dragon, and a burning look flashed in his eyes. After putting the corpse of the Spiritual Lord Realm Swamp Dragon into the base space, he moved towards the skeleton of the Demigod Swamp Dragon.

"Finally found the source of energy!!"

As soon as Shu Feng came under the skeleton of the Demigod Swamp Dragon, a look of surprise flashed in his eyes. Below the skeleton of the Demigod Swamp Dragon was piled up with a large piece of amber stone, which were the stones that could extract source energy.

Shu Feng immediately put the skeleton of the Demigod Swamp Dragon into the base space.

"Master, please give me the bones of this swamp dragon! Then give me source energy. I can feel that eating this bone. In the source energy evolution and mutation nest, I can evolve more powerfully and become your most loyal and powerful servant!!"

In the base space, the three-headed dragon crocodile in the swamp saw the skeleton of the Demigod Swamp Dragon, and a burning look flashed in his eyes. He wanted to swallow the skeleton corpse of the Demigod level, and emitted a burst of thoughts.

Shu Feng pondered for a while and then said decisively: "Hmm? OK! When I have collected enough source energy stones, you can eat!"

The three-headed dragon crocodile of swamps is an evolutionary and mutated swamp monster with extremely fierce evolutionary potential, and its evolutionary potential is much greater than that of ordinary swamps. If it mutates and evolves once again, it will become even more terrifying.

The swamped three-headed snakes rushed in, and the ghost-eating demon standing on it began to collect the amber stones crazily.

"The source energy is 150,000!"

Three days later, the amber stone was collected and sent to the resource dissolution tank, and converted into 150,000 source energy.

"Okay, you can eat!"

Shu Feng stood above the source energy evolution mutant nest, looking at the swamp three-headed dragon crocodile and said lightly.

With 150,000 source energy as a backing, Shu Feng's confidence suddenly became sufficient.

Gene mutation and evolution are very dangerous. If you are not careful, there will be a possibility of gene collapse. Once the gene collapses, even the strong man in the Spirit Saint Realm will die and become a monster.

The source energy evolution mutant nest can make the gene mutation of organisms mutate in a good direction, keeping the genes of the mutated organism so that it will not collapse.

There is a huge risk of gene mutation. Without a powerful energy such as source energy, gene mutation will begin. It is definitely a situation where there is no life. Even if gene mutation is performed, there is also a saying of success rate. Variation with good phase characteristics consumes low source energy and high efficiency. Variation with poor phase characteristics consumes high consumption and low efficiency.

The swamp giant crocodile has a high genetic identity with the Hydra. It absorbs a large amount of source energy and various resources to successfully mutate and evolve into a three-headed dragon crocodile. If the three-headed dragon crocodile can evolve and mutate again, it will definitely be much more powerful than the forty-meter swamp dragon.

Crack! Crack! Crack!

The three-headed dragon crocodile pounced on it and bit the skeleton of the demigod-level swamp dragon with one pound. The sharp teeth bit the skeleton of the demigod-level swamp dragon and swallowed it into its belly.

From the source energy evolution mutant nest, tentacle-like pipes extended out, which harshly harsh the body of the three-headed dragon crocodile in the swamp, and began to inject source energy into it.

Crack! Crack! Crack!
