Primordial Era: A brick knocks Hongyun unconscious, and he seizes the throne at the start.

Lu Chen secluded himself at the Pillar of Heaven for twenty years.

Over the past twenty years, he has thoroughly refined the essence of Pangu's heart, and his cultivation has naturally broken through to the late stage of Hunyuan!

With the Law of Power fully mastered and all eight Ancestral Witch Laws integrated, his punches and kicks now contained the combined power of nine laws, making ordinary saints (such as Jieyin and Zhunti, whose foundations were unstable) no match for him.

After leaving the pass, the first thing he did was to go down to the mortal realm to check on the progress of the Three Sovereigns.

Fuxi of the Huaxu tribe is already eighteen years old.

This boy is exceptionally gifted. At the age of seven, he "suddenly comprehended" the Bagua divination method, and at ten, he invented fishing nets and traps, greatly improving the tribe's hunting efficiency. At fifteen, he was elected as the tribe's leader, and now he has developed the Huaxu tribe into the largest tribe of the human race, with more than a dozen surrounding small tribes coming to rely on him.

"Not bad, progress is fast." Lu Chen squatted in the clouds, looking down at Fuxi who was teaching his people to use knotted ropes for record-keeping, and nodded in satisfaction.

But he didn't show up—it's not the right time yet.

Next, he flew to the Jiangshui tribe.

On Shennong's side, the situation is a bit...unexpected.

According to the original plan, Shennong should have "tasted hundreds of herbs," invented medicine, and laid the foundation for human agricultural civilization.

But when Lu Chen flew over the Jiangshui tribe, this was what he saw—

Shennong squatted in a medicinal herb field, holding a leather book in his left hand and a medicinal herb in his right, muttering incantations:

"Licorice root, sweet in taste, neutral in nature, enters the heart, lung, spleen, and stomach meridians. Efficacy: tonifies the spleen and replenishes qi, clears heat and detoxifies, eliminates phlegm and relieves cough, relieves spasms and pain, harmonizes various medicines... Hmm, this one has mutated, it has added a 'calming' effect, write it down, write it down."

Lu Chen: "???"

This art style is off!

Shouldn't the story of "Shennong tasting hundreds of herbs, encountering seventy poisons in a single day" be described as Shennong tasting hundreds of herbs? How did it become a systematic drug identification process?

He descended using a brick-like technique, transforming into an old farmer gathering herbs, and walked to Shennong's side.

"Young man, your records are quite detailed." Lu Chen looked at the animal skin booklet, which was densely filled with the names, properties, and effects of herbs, and even had simple line drawings.

Shennong looked up, revealing a handsome yet resolute face: "You old man also know about herbs?"

"I know a little bit." Lu Chen squatted down and picked up a medicinal herb. "But where did you learn about these concepts of 'meridian tropism' and 'efficacy'?"

Shennong scratched his head: "I can't really explain it, it's like I was born knowing these things. And..." He lowered his voice, "When I dream, I always see an old man with a white beard teaching me this knowledge."

Lu Chen understood instantly.

When Chenhu (Shennong) was reincarnated, he did seal some basic herbal knowledge in the jade slip, but it wasn't this systematic. Now it seems that Chenhu's memories from his previous life merged with the knowledge in the jade slip, causing a "mutation" that allowed him to learn modern Chinese medicine theory without a teacher.

Good heavens, this is going to create a prehistoric version of the "Shennong's Classic of Materia Medica"!

"Have you tried these herbs?" Lu Chen asked.

"Of course I'll try it," Shennong said matter-of-factly. "But I'm not stupid. I don't eat everything directly. I first observe its growing environment, color, and smell, then I take a small piece of leaf, chew it, and if it doesn't taste right, I spit it out. Then I use licorice to detoxify it."

As he spoke, he pointed to a basket of dried licorice next to him: "This is the herb I grow the most of, and it has the best detoxifying effect."

Lu Chen: "..."

Is this supposed to be "tasting hundreds of herbs"? This is clearly "scientific drug testing"!

But...it seems safer and more efficient?

"Have you encountered any 'poison'?" Lu Chen asked curiously.

"Yes, there is." Shennong took out a small notebook from his pocket, opened it, and said, "This is the 'List of Poisonous Herbs,' which records thirty-seven kinds. The most poisonous one is this one—Gelsemium elegans, with heart-shaped leaves and small yellow flowers. I chewed a small piece of it and had a stomachache for three days. Luckily, I had prepared licorice soup in advance, or I would have been done for."

As he spoke, he drew an X in his notebook: "This kind of grass needs to be highlighted, and the clansmen are strictly prohibited from eating it by mistake."

Lu Chen was convinced.

This method is much more reliable than the original Shennong.

"By the way, old man," Shennong suddenly remembered something, "do you know anything about farming? I've been thinking about how to increase grain production lately, but I just can't seem to get the hang of it."

Lu Chen's eyes lit up.

The opportunity for agrarian civilization has arrived.

"I do have some experience with this." He took out a handful of seeds from his pocket (actually a Qiankun Diagram). "These are called the 'Five Grains,' which are rice, millet, sorghum, wheat, and beans. You can try planting them; it's much more reliable than picking wild fruits."

Shennong accepted the seeds, overjoyed, and said, "Thank you, sir!"

"And this too." Lu Chen pulled out a blueprint for a stone hoe. "Using this to turn the soil is less strenuous than digging by hand."

"And this, a diagram of the irrigation canal..."

"And this, crop rotation and fallow..."

Lu Chen crammed all of Shennong's basic knowledge of modern agriculture into a simplified version.

Shennong listened with shining eyes and kept taking notes in his notebook.

By the time Lu Chen finished speaking, he had filled three large notebooks with notes.

"Old man, you are truly a divine being!" Shennong exclaimed, tears welling in his eyes. "With these, humanity will never have to go hungry again!"

"Do a good job, the future of humanity depends on you." Lu Chen patted his shoulder and then disappeared using a brick-遁 (a type of teleportation technique).

Leaving the Jiangshui tribe, Lu Chen had mixed feelings.

It seems he... led Shennong astray.

The original Shennong was a tragic hero who "tasted hundreds of herbs and was poisoned seventy times a day," but this one... is the Minister of Agriculture and Minister of Health who practices scientific farming and systematic drug testing.

"Fine, let it be crooked, at least we'll live longer." Lu Chen shook his head.

Next, he went to the Youxiong tribe.

On Xuanyuan's side, the style is even more unique.

According to the original plan, Xuanyuan should "learn warfare, pacify the world," become the God of War of the human race, and lead the human race to fight against Chiyou.

But what Lu Chen saw was—

Xuanyuan is training a "special forces" unit.

This unit consisted of only a hundred men, but each of them was well-equipped: they wore rattan armor (based on blueprints provided by Lu Chen), carried bronze spears (based on smelting methods provided by Lu Chen), and had bows and arrows hanging at their waists (based on manufacturing techniques provided by Lu Chen).

The training content is not simply about charging into battle, but includes modern special operations skills such as infiltration, assassination, intelligence gathering, and psychological warfare.

"Intelligence first, decapitation strikes as the primary objective, and direct confrontation as a last resort," Xuanyuan instructed his subordinates. "We must achieve the greatest victory with the least cost."

Lu Chen: "..."

Is this supposed to be the "Yellow Emperor"? This looks like a "prehistoric version of 007"!

But... it seems more efficient?

"Report!" A scout rushed in, "Chief, the Chi You tribe is provoking us again on the border, stealing grain from three of our villages!"

Xuanyuan's eyes turned cold: "Chi You...you're courting death."

He turned to his men and ordered, "First squad, burn their granaries. Second squad, spread rumors that Chi You is going to sacrifice their tribe's children to his flag. Third squad, come with me to 'visit' Chi You's allies and persuade them to remain neutral."

"yes!"

The troops moved swiftly.

Lu Chen crouched in the clouds, watching this scene, and his lips twitched.

That's a really underhanded tactic.

But it must be said, it's effective.

Three days later, Chi You's tribe was thrown into turmoil. His granary was burned, his allies turned against him, and he himself was ambushed by Xuanyuan, suffering serious injuries and fleeing.

Xuanyuan resolved the border crisis without losing a single soldier.

"Warfare is based on deception." Xuanyuan murmured to himself, gazing at the distant smoke of battle. "Who taught me that... I think it was some old man with a white beard?"

Lu Chen covered his face.

Well, another one has been led astray by him.

But... it seems the results are all good?

Fuxi pursued cultural rule, Shennong promoted national prosperity through science and technology, and Xuanyuan pursued military hegemony.

With these three joining forces, it would be difficult for the human race not to rise to power.

"Alright, my mission is complete." Lu Chen stretched. "Now, let's watch their performance."

He used the brick-遁 (a technique to teleport) to return to the pillar supporting the sky, preparing to continue his seclusion.

But halfway there, he suddenly sensed a familiar fluctuation—

From Wuzhuang Temple, in the direction of Hongyun.

Senior Hongyun...has he woken up?

Lu Chen changed direction and flew towards Wuzhuang Temple.

The Three Sovereigns have taken their places; it's time to arrange for the Five Emperors as well.

And Hongyun may be the first of the Five Emperors - Zhuanxu.

The wheels of history are slowly turning under the influence of his sinister hand.
