When it comes to cultivating immortality, it naturally starts with upgrading the herb garden.

"We can't waste them; they're all top-quality cultivation resources."

After bleeding them out and cleaning up the two corpses, Song Chen removed their storage bags and examined them.

The female cultivator had two low-grade magic artifacts, while the butcher only had that kitchen knife. Together, they had less than two hundred spirit stones, and were very poor.

There was nothing else in the female cultivator's storage bag.

In the butcher's storage bag, Song Chen found a considerable amount of essence blood.

These are all resources that Song Chen can use to quickly improve his cultivation level.

He put it away, took off his clothes, and glanced at the wooden barrel filled with the butcher's blood, which smelled strongly of blood.

"A single physical body releases just enough essence and blood to fill a wooden bucket."

Song Chen remained expressionless and said calmly. Without hesitation, he pushed off with his foot.

thump!

Blood splattered everywhere.

Song Chen sat on the wooden barrel, looking like a demon from hell.

However, he himself did not care and only absorbed the rich spiritual energy brought by the essence blood.

Compared to the blood of demonic beasts, the essence blood of cultivators is clearly more effective in improving cultivation level.

The spiritual energy was recklessly poured into the dantian, and the speed at which cultivation improved was unbelievable.

Song Chen had to carefully control this spiritual energy, otherwise he would be burst by it if he was not careful.

The spiritual energy in his dantian rose at an extremely terrifying speed, quickly overflowing, and then suddenly contracted, breaking through to the third level of Qi Refining.

With more than half of his essence blood still remaining, Song Chen took out a mid-grade spirit stone.

As his cultivation level improved, his meridians were able to withstand even greater spiritual energy pressure.

With a thought, Song Chen sent the spiritual energy from the mid-grade spirit stone into his dantian.

In an instant, an almost terrifying surge of spiritual energy coursed through his dantian.

With his exceptional skill in manipulating spiritual energy, Song Chen easily controlled the spiritual energy in his dantian.

He tells them to move, and they have to move; he tells them to stop, and they have to stop.

His spiritual energy was like his hands and feet, as easy as his own arms.

Following the flow of this immense spiritual energy, Song Chen combined it with the spiritual energy in his dantian, and suddenly, the spiritual energy transformed into a rich spiritual liquid.

Successfully broke through to the fourth level of Qi Refining.

The breakthrough from the second to the fourth level of Qi Refining was almost effortless, as easy as drinking water.

"Why is there a tiny green dot in the center of this spiritual liquid?"

Song Chen only realized something was wrong now. If he hadn't broken through to the mid-stage of Qi Refining once, he might not have noticed this anomaly.

Originally, the spiritual liquid should have been a colorless and clear liquid, but now an abnormal green color appeared in the middle of the liquid.

Song Chen stared blankly at the drop of spiritual liquid, thinking, "Should I expel it and let it condense again?"

Thinking of this, he immediately prepared to expel the drop of spiritual liquid.

Suddenly, a spell appeared out of thin air in Song Chen's mind.

"The Art of Essence and Blood? What is that?"

As his memories unfolded, Song Chen gradually understood the function of this spell: to extract essence blood from ordinary blood.

However, the amount extracted is very small, about one hundred to one.

Song Chen was overjoyed. This spell was clearly a divine skill for him, which could help him extract more essence blood.

His joy didn't last long; an even greater sense of happiness welled up inside him.

"Could it be that by absorbing a cultivator's blood, I can acquire one of their spells?"

Song Chen reacted quickly and immediately realized that the spell must belong to the butcher.

Just as the butcher had finished drinking his blood, he quickly took out the female cultivator's essence blood and poured it into the bucket.

The female cultivator's cultivation level was indeed much higher than the butcher's, and Song Chen absorbed more and richer spiritual energy from her.

An hour later, not a single drop of essence blood remained in the wooden barrel.

Song Chen's mind remained completely blank.

"Is that not allowed?"

The moment the thought crossed Song Chen's mind, a spell called "Yin Yang Union Music Score" appeared.

This method is mainly used for dual cultivation and can only be used on cultivators with lower cultivation levels.

However, Song Chen did not feel sad about this heaven-defying magic; on the contrary, he felt joy.

"This blood spirit root actually has such wonderful uses! It's truly full of surprises!"

A sinister glint flashed in Song Chen's eyes: "Why not kill a few more cultivators and take their blood?"

In an instant, he rejected the idea.

Putting aside the risks, even with his current cultivation level, he couldn't just roam freely in Huanbei. It's better to be more cautious.

But he didn't give up, thinking, "If I can't kill him, can't I at least buy him?"

With Feng Sancai's memories, does Song Chen know where in the Northern Ring Road he can buy cultivators' essence blood and physical bodies...?

The next day.

After Song Chen finished setting up the buildings and reactivated them using the system, he went out.

He disguised himself, did not disturb anyone, and did not go to the middle alley, but walked in the opposite direction.

On the edge of the South Lane residential area, there is an extremely inconspicuous house with a sign that reads "Number 572 South Lane".

Song Chen lowered the brim of his hat and knocked on the door.

The person who opened the door was a fat man with a face full of freckles. He was taken aback when he saw Song Chen and said, "Want to drink?"

Song Chen nodded and replied, "Eat."

This man's name is Dong Fu, and because of his large physique, most people call him Fatty Dong.

Fatty Dong glanced at Song Chen, then led him into the house and asked, "Who's the one who started this thread?"

"He's dead."

"According to the rules, I should still try to say something..."

"Feng Sancai"

Fatty Dong glanced at Song Chen, then turned his head back and asked, "What do you want?"

"The ribs of a Qi Refining Peak cultivator, and the essence blood of a cultivator."

Upon hearing this, Fatty Dong turned to Song Chen again and said, "We're out of stock. You'll have to wait a few days if you want it. We do have essence blood."

"What level of cultivation is there in essence blood?"

Upon hearing this, Fatty Dong broke out in a cold sweat. This was a demonic cultivator!

He cursed Feng Sancai in his heart, then said with a fawning smile, "We have everything from the early to late stages of Qi Refining, priced between two and ten spirit stones per tael."

"How much Qi Refining Stage 3 essence blood do you have? I need a large amount."

Upon hearing this, Fatty Dong was delighted, realizing he was a big customer, and he began to praise Feng Sancai for his loyalty.

"We currently have around eight thousand taels. If you want more, you'll have to wait a while longer."

Song Chen remained silent for a moment.

Fatty Dong looked at Song Chen, his heart skipped a beat. Had he said something bad and angered the other party?

His back was soaked with cold sweat as he looked at Song Chen with trepidation.

Everyone says that demonic cultivators are crazy, let alone a demonic cultivator whose cultivation level he can't see through.

Fatty Dong felt a little panicked.

"I'll take it all. Add another ten thousand taels, and I'll also take the ribs of a peak Qi Refining cultivator. How many spirit stones will that cost in total?"

After making his estimate, Song Chen said calmly.

Fatty Dong was slightly taken aback, then overjoyed, and said:

"Eight thousand taels of essence blood and eighty thousand spirit stones, ribs and five hundred spirit stones. The deposit is no longer required. You can take the goods next month according to the rules."

Song Chen nodded and poured the spirit stones out of his storage bag: "Take the goods."

Fatty Dong stared wide-eyed at the mountain of spirit stones and quickly led Song Chen to the house around the corner.

The house was unremarkable, but underneath lay a hidden world.

A dark, secret passage led underground, and the two of them went down one after the other.

Song Chen always held a talisman in his hand behind his back, ready to kill the person in front of him if things went wrong.

Not long after we walked, the light below appeared.

Both sides were containers, with a large number of monks' corpses well preserved in liquid.

Song Chen casually shook his head and was surprised to find that the corpse of a cultivator in one of the containers was moving slightly.

Fatty Dong saw it too, but didn't think much of it, waving his hand and laughing:

"Don't worry, these cultivators' bodies sometimes exhibit this strange phenomenon, which we call post-death micro-movement."

Song Chen remained expressionless. He hadn't felt anything to begin with, and this explanation only made him feel even less moved.

Seeing Song Chen like this, Fatty Dong felt even more awe for him.

What kind of person is this! They don't even panic when they see a corpse moving!

Fatty Dong forced himself to remain calm and continued walking inside.

Further inside was a blood-red container, the place where essence and blood were stored.

He took out an empty container and drew blood from one of the containers with bright red blood into it.

"This is the essence blood of someone in the late stage of Qi Refining."

Song Chen placed his hand on the bucket, and in the blink of an eye, the entire bucket was put into the storage bag.

This scene left Fatty Dong utterly astonished.

If such a big bucket can fit into a storage bag, then how big must Song Chen's storage bag be?

A flash of greed crossed his eyes, but then he remembered Song Chen's behavior earlier and completely abandoned his evil thoughts.

Song Chen didn't move, pointed to the road, and said, "You go first."

Fatty Dong swallowed hard and slowly said, "...Okay."
