Primordial Era: Starting with the repair of Penglai Immortal Island

"Sweet Rain Technique!"

Lieshan was overjoyed as he looked at the divine power that appeared in his mind and its function!

This Sweet Rain Technique can even cultivate and promote the growth of immortal herbs and spiritual roots, let alone this tiny millet!

For Lieshan, who is at the peak of Taiyi, the Ganlin Technique was mastered in an instant.

As he looked at the mountains carved out of the earth, a thought struck him, connecting him to the vital path of life between heaven and earth.

The next moment, a cloud several miles in circumference gathered in the void, and the rich spiritual energy and vitality combined to transform into sweet rain containing abundant life force, which fell on the earth.

The scorched earth was instantly covered with a touch of green.

Nourished by the spiritual and life-giving rain, the millet seeds quickly took root, sprouted, and grew, maturing in just a few days and producing golden ears of grain.

After harvesting all the mature millet, Lieshan carefully examined it and found that the seeds of these millet had a more concentrated vitality than those of normally grown millet, making them more suitable for use as seeds.

Afterwards, while cultivating the seeds, Lieshan also cleared out an area to plant the medicinal herb seeds he had collected.

The entire human race was thrown into a frenzy upon receiving the decree from the sovereign!

That ancestor of medicine, that sage who tasted herbs, actually found a medicinal herb that could be cultivated for humankind, so that humankind could fill their stomachs.

Each tribe sent its most skilled human members to the human tribe to collect millet seeds and learn how to cultivate them.

At the same time, in accordance with the decree, they collected the plants around the tribe that met the requirements of the sovereign and sent them to the ancestral land of the human race.

In an instant, the ancestral land of the human race became exceptionally lively.

Every day, plant seeds or plants from various tribes arrive, piling up like mountains.

After cultivating enough millet seeds, Lieshan began a long and arduous screening process in the face of a mountain of plant samples.

The first batch he selected included more than three thousand varieties.

Lieshan classified these more than 3,000 plants one by one.

Some are grains, with seeds growing on the ears of grain.

Some are legumes, bearing pods.

Some are tuberous, with large, fleshy rhizomes growing underground.

Lieshan first focused his attention on plants similar to millet.

He divided the land where he had cultivated millet seeds into thousands of small plots.

In each plot of land, plant one type of grain.

He needs to observe the growth habits, adaptability to the environment, yield, edible parts, and storage time of each plant...!

This is an extremely complicated and arduous project.

Every plant requires complete observation from sowing to harvest.

Moreover, the "Sweet Rain Technique" cannot be used to accelerate ripening in large quantities; it can only slightly increase its growth rate!

Even so, the growth cycle of these plants ranges from several months to half a year or even a year.

Those that grow too slowly will be eliminated!

Eliminate those with too low a production volume!

Those that cannot be planted on a large scale should be eliminated.

Eliminate those with a small amount of toxicity!

.......

It took hundreds of years to select thirty species from tens of thousands of plants.

These thirty kinds of plants are high-yielding, highly adaptable, good at filling the stomach, and non-toxic.

Lieshan referred to these thirty grains as "candidate grains".

But thirty kinds are still too many.

Because among these thirty plants, some are similar, and some are different varieties of the same type of plant.

Lieshan needs to select the most suitable one from these thirty options.

He began to make a more detailed comparison of the thirty grains.

He compared their difficulty of cultivation, storage performance, taste, duration of satiety, and long-term impact on humans...!

Each comparison requires a long period of experimentation.

For example, storage time: grains need to be stored for one year, two years, or three years to see which ones can be preserved for longer.

Alternatively, it could involve long-term consumption, requiring a group of people to consume a particular grain over an extended period and observing changes in their physical condition.

These experiments all require a long time.

One year, two years, three years...!

Ten years, twenty years, thirty years...!

Finally, a special plant caught Lieshan's attention.

This plant is taller than millet, with thicker stems, and its ears of grain are not loose and drooping like millet, but rather stand upright in a more compact manner.

The seeds are slightly smaller than millet seeds, but more rounded.

Lieshan planted this plant on a large scale to observe its growth.

He discovered that this grain was more drought-resistant than millet and could grow even in places where it rarely rained.

Moreover, its yield is more stable than that of millet.

After harvesting this grain, Lieshan cooked it and made it available for ordinary people to enjoy.

The porridge is more fragrant and flavorful than millet porridge, and it is also more filling.

After eating a small bowl, I didn't feel hungry for most of the day.

Lieshan also planted it in different areas to observe its adaptability.

The results surprised him: this grain is highly adaptable to the soil, growing well both on fertile riverbanks and barren hillsides, with minimal fluctuations in yield.

Moreover, he discovered that this plant is easier to store!

Lieshan knew that he had found a second type of grain.

He named this grain "Ji".

The appearance of Ji greatly boosted Lieshan's confidence.

He continued to screen the remaining candidate grains.

Among the remaining candidate plants, he selected rice and wheat, two high-yielding plants.

Rice differs from millet, sorghum, and wheat in that it can grow in water.

There is another plant, which, although different from the four he selected, also has a low yield!

But he accidentally discovered that planting this plant first, and then planting wheat, millet, and sorghum, would greatly increase yields.

This plant is short and produces short pods, each containing two or three seeds.

The seeds are round and plump, and pale yellow in color.

After being cooked until tender, it has a soft texture and a unique aroma!

Lieshan named it "Shu".

From the initial selection to the dissemination of millet, rice, wheat, and beans throughout the human race, Lieshan spent over a thousand years.

When the last human tribe cleared the wasteland and sowed seeds.

When you see the millet ears drooping heavily, and the soybean pods plump and round.

An old man held a handful of golden millet, his rough fingers trembling, and cloudy tears streamed down the lines of his face.

He held the millet high above his head and cried out in a hoarse voice, "Thank you, Lord Lieshan! Thank you, ancestors of the human race!"

At this moment, in the ancestral land of humanity, hundreds of millions of miles away, the sky suddenly changed.

The rosy glow rose from the horizon, not in streaks, but spreading out across the sky in a vast and boundless expanse.

Red, orange, yellow, green, cyan, blue, and purple—the seven colors intertwine, painting the sky of our ancestral land into a magnificent picture.

Wherever the rosy light passed, auspicious clouds bloomed, and on each cloud, golden lotuses seemed to surge, fragrance wafted, and celestial music resounded.
