I got the scarlet blood at the beginning.

The road ahead was long and winding.

Following the instructions of the map and the positioning device, Fang Yu quickly traveled more than ten kilometers.

He came to a ruined building complex.

This ruined building complex was a huge playground during the Tianqing era.

However, after hundreds of years of destruction, this place has completely changed and has become a place where ferocious beasts live.

Fang Yu carefully cut the green vines blocking the way in front of him and slowly entered a building.

Fang Yu estimated that this place should have been a scene like an experience hall or a haunted house before.

Turn on the lighting ball and hang it around his waist, and the scene around Fang Yu is instantly illuminated.

Fang Yu pays full attention and observes the surroundings while walking.

Suddenly, a dark red shadow pounced from the top of Fang Yu's head.

Swish!

Zhan Yuan's blade flashed.

Snap!

Then the body cut into two pieces fell to the ground.

Fang Yu glanced and found that it was just a red-haired rat of a junior apprentice.

That's it?

Worthless stuff!

Fang Yu showed a trace of disdain on his face.

Then he squatted down silently and began to try to absorb the flesh and blood of the red-haired rat.

At this time, Fang Yu found that he could not absorb any extraction energy from it.

"What's going on?"

Fang Yu frowned, as if he felt something was wrong.

Suppressing the thoughts in his mind, Fang Yu continued to explore in this dilapidated space...

After killing a high-level apprentice night cat living in the corner with one knife, Fang Yu tried to absorb extraction energy from the night cat again.

The result failed again.

"What's going on? Is it because after I broke through the first level, the scarlet blood body has undergone some changes that I don't know about?"

"Now, I may no longer be able to draw energy from the flesh and blood of the apprentice."

"It is even possible that I have lost the ability to absorb flesh and blood to obtain energy extraction?"

Thinking of the last possibility, Fang Yu's heart suddenly tightened.

He still knew his own cultivation aptitude.

Although after genetic modification, his aptitude has been greatly improved compared to before.

However, with the current aptitude, if he wants to complete the cleansing and transformation of the whole body bone marrow without any external force, and finally break through to the realm of the second-level warrior.

It will take at least 10 years!

Even with the assistance of a proper amount of fierce beast crystals and drugs, this time can only be compressed to 3-5 years.

Unless Fang Yu has endless cultivation resources, otherwise, his breakthrough to the second level will definitely not be less than 3 years.

Originally, Fang Yu also hoped to replicate the rocket-like upgrade rhythm of the apprentice stage by extracting energy.

But now it seems that this plan is probably going to fall through.

Fang Yu's face looked a little ugly.

But soon, he adjusted his mentality.

He had always been determined to practice martial arts. Even before activating the system, he had never thought of giving up the road of martial arts.

Now that he had the system, even if he lost the way to become stronger by extracting energy, there would be other ways.

There must be a way when the car reaches the mountain! There is no hurdle that cannot be overcome!

What's more, it is still unknown whether the energy extraction function has disappeared.

To verify this, it is very simple.

Just kill a first-level beast.

Fang Yu put away the body of the night cat, shook off the blood on the blade, and continued to move forward into the darkness.

Perhaps this building was too shabby. Fang Yu walked around the whole circle and killed 5 apprentice-level beasts.

He didn't find a formal-level beast.

Fang Yu secretly said that it was bad luck and planned to leave here.

Just when Fang Yu turned his head, a whistling sound rang from Fang Yu's ears.

Fang Yu immediately raised his knife to block.

I saw a slippery strip of meat shot out from the shadow.

This strip of meat pierced Fang Yu's temple at a very fast speed.

Ding!

A crisp sound came.

Fang Yu felt a huge force coming from Zhan Yuan and spreading to Fang Yu's arm.

However, although this force is strong, it is not enough in front of Fang Yu.

Fang Yu shook his arm and easily unloaded this force.

Swish!

The strip of meat quickly retracted and then shot towards Fang Yu again.

And this time, the target of the strip of meat was Fang Yu's lower body.

Fang Yu had a blank expression on his face and swung his knife sideways.

The Zhan Yuan in his hand chopped the strip of meat fiercely.

Fang Yu felt that his Zhan Yuan seemed to have cut a ball of cotton, and it was soft.

However, the sharpness of Zhan Yuan is also quite high among low-level weapons.

Although most of the force of this knife was removed, it still left a cut of several centimeters on the meat strip.

"Quack!"

A frog croaked in pain.

At this time, the enemy hiding in the dark finally revealed its true face.

A first-level early-stage exploding tongue frog.

This kind of beast, as its name suggests, has all its combat power concentrated on its tongue.

At this time, the strongest organ of the exploding tongue frog was cut by Fang Yu, which also stimulated its ferocity.

And Fang Yu, after seeing the exploding tongue frog, a look of joy suddenly appeared on his face.

After searching for so long, I finally encountered a first-level beast.

Looking at the exploding tongue frog in front of him, which was covered with slippery liquid.

Fang Yu couldn't help but stick out his tongue and licked his chapped lips, with a hint of inexplicable desire in his eyes.

Wind-breaking style!

A huge force came from under Fang Yu's feet, and his figure instantly crossed several meters and came to the front of the exploding tongue frog.

The Zhan Yuan in his hand was now wrapped in the power of Qi and blood, emitting a sharp edge.

The Exploding Tongue Frog once again ejected its slippery tongue to block Fang Yu.

The blade quickly passed through the air, as if to cut off the air in front of it.

Swish!

The knife directly cut off the tongue of the Exploding Tongue Frog and dropped it to the ground.

Snap!

The Exploding Tongue Frog found that its proud tongue was cut off, and a trace of violence rose in its heart.

However, this anger disappeared instantly when it looked into Fang Yu's cold eyes.

It turned around and was about to flee from here.

However, Fang Yu could not let the Exploding Tongue Frog escape as he wished.

Although the Exploding Tongue Frog's legs were extremely explosive and moved very fast.

But its opponent was Fang Yu.

Fang Yu, faster!

Puff!

When the Zhan Yuan pierced into the body of the Exploding Tongue Frog, the soft and slippery feeling came again.

But in front of Zhan Yuan, who was blessed with the power of Qi and blood, he could only resist for a moment.

Looking at the basketball-sized exploding tongue frog corpse hanging on the tip of his knife, Fang Yu directly inserted his finger into the wound.

With the familiar sucking feeling coming, Fang Yu's hanging heart finally let go.

Feeling the energy in his body that was several times stronger than before, Fang Yu couldn't wait to mobilize this energy for cultivation.

With the help of the extraction energy, Fang Yu's cleansing this time was extremely smooth.

Qi and blood seemed to have no obstacles, penetrating the bone layer and integrating into the bone marrow.

And Fang Yu's turbid bone marrow began to slowly show a faint glow at this time.

Fang Yu's mouth corners instantly grinned to his ears, and a satisfied look appeared on his face...
