Chapter 104 Deep in the secluded mountains, the shepherd's bells ring out once more. [Bonus chapter for every 300 words]

On a distant mountain peak, a man riding an ox looked back at Spirit Beast Mountain one last time before urging the old green ox toward the distant, lush mountains.

Clang... clang... clang...

Deep within the secluded mountains, the sound of shepherd's bells rang out once more. Demonic insects swarmed, and crimson flames flickered... Following the old green ox's leisurely gait, Meng De continued to graze the source blood demonic insects while simultaneously harvesting them within a ten-mile radius of him.

In the vast mountains, Mengde was like a giant eraser; wherever he went, he left behind a forbidden zone of demonic insects twenty miles wide.

Mengde lay on the back of the old green ox, his head covered by a straw hat he had casually woven to shield him from the glaring sunlight. Apart from occasionally extracting a drop of first-grade pure source blood to feed the old green ox, Mengde completely let the old green ox lead the way.

A month later, the old blue ox, who knew the way well, returned to the mortal village where it used to live. Mengde left behind a few Blood Tyrant larvae and then left with the old blue ox.

A month later, the old green ox brought Mengde back to Meng Village. After leaving behind a few more Blood Tyrant larvae, Mengde left a Source Blood Talisman in the village and then quietly departed.

During this time, Mengde kept observing the condition of the old green ox that had consumed the pure source blood. He discovered that the old green ox's demonic beast body seemed to be more efficient at absorbing the pure source blood than the human body.

In just two months, the old green ox grew several sizes larger, seemingly approaching the mid-stage of a first-level demon beast.

"This must be due to the different evolutionary priorities of species..." Meng De had witnessed the transformation of the old green ox. Demonic beasts have an advantage in physique, and the pure source blood is also mostly reflected in physique. In addition, the old green ox had eaten a lot of source blood demonic insects before, so the old green ox's demonic beast physique was already highly adapted to the pure source blood.

The higher the adaptability, the greater the transformation of the pure source blood.

In addition to the experimental data previously provided by Han Li, creatures deeply modified and evolved by the Pure Origin Blood will experience an increase in cultivation speed...

In other words, even if the old green ox, which advanced to a first-level demon beast by mistakenly eating a spiritual herb, has poor cultivation talent, it will inevitably receive a considerable boost under the continuous evolution and transformation of the pure source blood.

The advantage of pure source blood is that it has no side effects, but the disadvantage is that its evolution and modification speed is relatively slow...

Only the source blood that Mengde himself extracted from the source blood swarm using the source blood demon flame can be called [pure source blood].

"The source blood refined by others is qualitatively different from the source blood demonic flame. More or less, they all contain impurities that cannot be absorbed and excreted by the body... thus creating an absorption limit similar to drug resistance..." Thinking of this, Meng De, lying on the back of the old green ox, couldn't help but sigh at Han Li, who seemed to have an inexplicable and complicated karmic connection with drug resistance throughout his life.

At first, Mengde was unsure whether the human body could absorb source blood, since in Mengde's view, source blood was almost equivalent to his own essence blood.

Unable to resist Han Li's curiosity, Meng De gave him a few drops of his own refined pure source blood. Han Li then discovered that Meng De's source blood seemed to have the miraculous effect of continuously optimizing the body and replenishing the life essence!

So, with the idea of ​​self-reliance, Han Li set his sights on the Source Blood Demon Insects he was raising.

From Han Li's perspective, although Meng De possesses unparalleled advantages in the field of insect control, Meng De is definitely inferior to him in terms of insect feeding. Therefore, Meng De's extraction rate of source blood is certainly not as high as his own.

So, with a bright future in mind, Han Li learned the Blood Refining Technique from Meng De and began to refine a large number of Source Blood Demon Insects to extract Source Blood.

At that time, Mengde extracted source blood and stored it in small vials, while Han Li used large cups for everything.

It has a somewhat boastful tone.

At first, Meng De also had some doubts about himself, because the source blood that Han Li refined was not much different from the source blood that he refined.

It wasn't until Han Li consumed ten drops of Origin Blood that he suddenly realized something was wrong: the optimization effect of the Origin Blood he consumed afterward began to visibly decrease... and depending on individual constitution, the Origin Blood Han Li refined would almost completely lose its effect after forty or fifty drops... unless he refined a higher-grade Origin Blood.

At this moment, Han Li discovered that the source blood refined by Meng De did not have this restriction at all.

Thus, Han Li was forced to acknowledge a cruel truth with mixed feelings: it seemed he could develop drug resistance no matter what he ate...

It was precisely because of the experimental data provided by Han Li that Meng De divided the source blood into three qualities: Creation Source Blood, Pure Source Blood, and Flawed Source Blood.

【Flawed Source Blood】can optimize the human gene chain to near its limit. For example, if your genes originally allowed you to grow to 1.8 meters tall, but due to environmental factors you are only 1.6 meters tall, then 【Flawed Source Blood】can allow you to start regrow until you reach 1.8 meters tall.

Subsequently, due to its purity, the genetic chain in your body begins to develop immunity to the [flawed source blood].

【Pure Source Blood】can repair the human gene chain to its limit, and even break through the limit with continuous supply.

As for the final [Creation Source Blood], in short, it unlocks the shackles and infinite potential.

That's why Han Li sometimes says that the source blood species are both a disaster and an opportunity for the entire Tiannan region and even the human world.

Pure Source Blood is extremely rare and hard to come by, but everyone has the opportunity to refine Flawed Source Blood. Therefore, under the wave of gene optimization, all races in the human world will receive a rain of evolution on the level of life.

Given Niu Niu's current condition, if this feeding continues, it's expected to reach the peak of level one within one or two years, or even break through to level two.

Upon returning to the spirit stone mine, Meng De's old green ox, after undergoing evolutionary transformation with thirty drops of first-level pure source blood, successfully absorbed the indigestible spiritual energy stones accumulated within its body, thus breaking through to become a mid-stage first-level demon beast.

By this time, it had been three months since Mengde left Ling Shou Mountain.

When Meng De leisurely rode his old green ox back to the spirit stone mine, Han Li followed closely behind, arriving once again with a large amount of array materials for repairing the ancient teleportation array.

The last time Han Li and Meng De parted ways, it was partly to return to Huangfeng Valley to let them know he was safe, and partly to make it easier for Han Li, as a Foundation Establishment cultivator, to go to various cultivation markets in Yue Kingdom to collect useful array materials.

"Teacher! Uncle Han!" Xin Ruyin greeted the two respectfully as they arrived as promised inside the cave.

In three months, Xin Ruyin successfully learned the Blood Refining Technique and refined her first drop of first-level pure source blood. Her life essence was replenished, and her complexion became much rosier than usual.
