At this moment, the green light on the Evergreen Immortal Creeper sparkled, expressing its affectionate feelings towards Zhou Sui.
It seemed to want more of the potion.
After all, these special potions brought it immense benefits.
"There's none left for today."
"But there will be more tomorrow."
Upon hearing this, the Evergreen Immortal Creeper calmed down and returned to tranquility.
With a wave of Zhou Sui's hand, he withdrew the Medicine Gu, then vanished from the spot and reappeared in the medicine gardens of the Xuanhuang Sect, which were now larger than before.
Each medicine garden extended over a hundred thousand miles and was densely planted with Spiritual Medicine.
The entire garden was filled with the rich scent of medicine to its extreme.
The next second, the Medicine Gu immediately flew out.
Instantly, it released a vast medicinal domain enveloping an area of tens of thousands of miles. Countless medicinal energy flowed into it like a river, rapidly replenishing its body.
Its withered form filled out again, and its aura seemed even more potent than before.
This was the way the Medicine Gu cultivated.
It could enhance its own source of power by absorbing the medicinal energy released from the Spiritual Medicine.
The more it consumed, the quicker it would evolve.
One could say it shared a mutualistic relationship with the various Spiritual Medicine plants.
Its spiritual liquid stimulated plant growth, and the medicine energy that these plants released stimulated the growth of the Medicine Gu.
Their relationship was one of mutual enhancement.
At this moment, a thought crossed Zhou Sui's mind when he noticed small green lights emerging from the body of the Medicine Gu.
The green lights, one by one, instantly disappeared into the medicine garden.
Like spirits, they merged into the depths of the earth.
These green lights were offspring-worms, miniature instances of the Medicine Gu, bred from its body.
These offspring could help the Medicine Gu absorb the medicinal energy from various Spiritual Medicine plants.
Furthermore, they could transmit this energy to the Medicine Gu's main body regardless of the spatial distance.
In this way, in the future, the Medicine Gu would not need to personally visit the medicine gardens to gather medicine energy.
Just these offspring-worms could help it absorb medicine energy to facilitate its main body's growth.
At the same time, these offspring-worms could also assist the growth of the Spiritual Medicine plants and improve the fertility of the soil, aiding the plants in growing even better and at an accelerated rate.
Although these offspring-worms were not on par with the Medicine Gu, the aura they released could also enhance the growth of many Spiritual Medicine plants far beyond their natural growth rate.
"Not bad, it can actually breed offspring-worms."
"In this way, even if I ascend to the Immortal World in the future."
"There's no need to worry about the Xuanhuang Sect's medicine gardens. They will still be able to continuously yield large amounts of Spiritual Medicine."
Zhou Sui stroked his chin.
He had initially worried that if he one day left the Xuanhuang Sect, the supply of Spiritual Medicine there might be cut off, or at least the gardens would not be able to produce as much Spiritual Medicine as fast as they used to.
However, as long as these offspring of the Medicine Gu existed, all these issues ceased to be concerns.
"But it's not only the medicine gardens of the Xuanhuang Sect."
"Should say, the soil of the Xuan Huang Continent is the same, it's extremely fertile."
"Recently, it seems to have given birth to numerous plants, numerous Spiritual Medicine."
"Plant any grains, and a large amount of Spirit Rice can be harvested."
Zhou Sui squinted his eyes.
Clearly, compared to before, the soil of the Xuan Huang Continent was many times better than other places.
Even Spirit Grains that couldn't survive elsewhere could be easily planted and thrive anywhere on the Xuan Huang Continent.
Even the yield could increase by several times.
One could say this is a land blessed by the heavens.
Indeed, it's not just the Xuan Huang Continent, all the land in the Profound Yellow Realm has seen the fertility of the soil double or more compared to before.
Although it's not as fertile as the soil of the Xuan Huang Continent, it was still quite amazing. It seemed as though it had evolved into Spiritual Soil.
All of this was because of the Evergreen Immortal Creeper.
Thanks to the power of the Evergreen Immortal Creeper, its roots spread throughout the world, and its creeping vines replaced the channels of the Spirit Vein. Therefore, a large amount of green wood energy was released from its body.
Over time, the land of the entire Profound Yellow Realm was eroded by the green wood energy, transforming it into Spiritual Soil, and thus the fertility of the soil greatly increased.
Basically, this world is simply a paradise for the growth of various Spiritual Medicine and other plants.
As for the Xuan Huang Continent.
Because the body of the Evergreen Immortal Creeper is located here, naturally, the impact here is greater.
So, the soil of this continent is even more fertile, anything planted here can grow rapidly.
"It's not only the Medicine Gu that can split off a part of itself."
"The Fifth Stage Wine Bug can do the same."
"The Wine Bug can now create a large Alcohol Pool."
"This Alcohol Pool is actually a clone of the Wine Bug."
"Simply throw in a lot of Demon Corpses or Spiritual Medicine, and it can be refined into Spiritual Wine."
"But since the main ingredient is demons, calling it a Demon Refining Pool is also fine."
"Moreover, as the Wine Bug evolves, the power of the Demon Refining Pool will also continuously increase."
Zhou Sui stroked his chin.
In the interior of the Xuanhuang Sect, there's a valley. It has transformed into a Demon Refining Pool, becoming a massive lake spanning more than a thousand kilometers in diameter.
