He looked at his son who was standing with his head bowed and sighed softly in his heart.

This son is filial and kind, compassionate to the people, and truly has the qualities of a benevolent king.

However, this person is too honest and sincere. He only follows the procedures when encountering things, and lacks flexibility and scheming.

When it comes to being smart, wise, and decisive, he ultimately failed to learn the essence of himself.

"I have anticipated this matter long ago." The First Emperor spoke calmly, with a hint of insight in his tone.

Fusu suddenly raised his head, a trace of surprise and shame flashing in his eyes: "Father, you are wise! Your son..."

The First Emperor waved his hand, signaling him not to blame himself. "Although the power of the crystal core is strong, it is ultimately an external object. Sitting back and draining the resources is not a long-term solution. I have not only considered it, I have also begun to implement it."

Fusu was even more curious: "What magic trick does father have?"

The First Emperor's lips curled up into an inscrutable smile. "Do you know where those alchemists who used to be busy at my alchemy furnace are now?"

Fusu was stunned for a moment, then he understood.

When my father was obsessed with immortality, he recruited alchemists from all over the world to refine elixirs. However, the elixirs were ineffective and nearly cost him his life. If it weren't for the crystal core...

Later, my father killed a group of swindlers, and some were imprisoned because their crimes were less serious or they had some unorthodox practices.

"Father's intention is..."

"good."

"I have already brought out those alchemists who still have some skills from the prison and ordered them to study this crystal core and find a way to increase its effectiveness, or even create something out of nothing."

For the First Emperor, since these alchemists could make a variety of elixirs, they might also be able to learn some tricks from this "immortal stone".

Waste utilization is also the art of emperors.

At this moment, in a secret courtyard in Xianyang City, several haggard alchemists in prison uniforms were gathered around a crystal core that was flashing a faint red light, with frowns on their faces.

There were bottles and jars placed in front of them, and the air was filled with the pungent smell of medicine and burnt food.

"The Nine-Turn Extraction Method is ineffective!"

"The Yin-Yang Refining Technique is also useless!"

"The crystal core was nearly shattered by calcining it with earth fire!"

The alchemists all looked ashen.

They were already guilty, and it was a great blessing from heaven that Your Majesty rescued them from prison and entrusted them with such an important task.

If I don't make any more achievements, I'm afraid I'll really be beheaded.

The desire to survive made them exhaust all their energy and use all their skills, such as extraction, refining, fusion, and sacrifice...

He tried every method he could think of, but apart from the normal energy consumption, the crystal core showed no signs of being "enhanced" at all.

Seeing that the eyes of the eunuchs who were supervising him were getting colder and colder, the First Emperor's patience seemed to be exhausted.

Just as everyone was despairing, the oldest alchemist, whose hair and beard were already gray, suddenly had a gleam in his eyes, as if he had grasped a life-saving straw:

"My fellow disciples! Perhaps... perhaps the method recorded in my sect's tradition can work!"

Everyone looked at him.

The old alchemist swallowed his saliva and said cautiously:

"My sect once had a fragmentary scroll that recorded a long-lost 'formation'. This formation isn't a military formation, but... it's a unique formation that can gather the invisible 'spiritual energy' of heaven and earth into one place!"

The more he spoke, the more certain he became.

"The power of the crystal core may be similar to the legendary 'spiritual energy'! If we can set up this formation, we may be able to greatly improve the efficiency of utilizing the crystal core energy, and even... even draw similar power from the heavens and the earth!"

As soon as these words were spoken, it was as if a huge rock was thrown into the silent courtyard, causing a thousand waves.

Formation?

Gathering spiritual energy?

Does such a nearly mythical method really exist?
