The photovoltaic system was finally installed.
Li Daoxuan felt quietly pleased.
From now on, he would no longer need to keep carrying the tablet in and out of the box just to recharge it. That tedious cycle—take it out, charge it, put it back—was finally over.
However, once the excitement settled, a new problem surfaced.
The wiring.
Dragging an exposed cable directly from outside the city walls was far too risky. Anyone with eyes could see it. If it were discovered, the result would range from mass panic to full-blown worship chaos.
So Li Daoxuan adopted a familiar solution from his own era.
He dug trenches.
Outside the city walls, this was easy. He simply carved a long trench into the earth and buried the cable neatly beneath it.
Inside Puzhou City, however, things became… complicated.
The cable had to pass through residential courtyards, public streets, and even straight across the main drill ground of the Puzhou garrison.
In Li Daoxuan's own world, a project like this would require endless paperwork, permits, negotiations, and compensation. Construction crews would argue. Residents would protest. Someone would inevitably lie down in front of the trench.
But here?
Here, Li Daoxuan merely appeared.
The moment his figure manifested, the city erupted.
"Wow! Dao Xuan Tianzun has appeared!"
"What is Dao Xuan Tianzun doing this time?"
"Ah! He's digging again!"
"Look! That trench is heading straight into my courtyard!"
"Hahaha! My house has been personally blessed by Dao Xuan Tianzun!"
A trench was carved straight through the city.
No one complained.
Not a single person objected.
Horse carts were forced to detour, but instead of cursing, their drivers stopped, climbed down, and craned their necks to watch.
Children squatted by the trench, counting how many times Dao Xuan Tianzun lifted the soil.
Even shopkeepers leaned against their doors, hands clasped, faces glowing with pride, as if the trench were a personal honor.
The trench did not stop at one destination.
It split.
One branch ran toward the Puzhou Grand Theater.
The other extended to the marketplace square.
Puzhou City had two tablets, and both needed power.
Dao Xuan Tianzun buried a thick, long, black cable into the trench. At the branching point, he split the cable cleanly into two. When everything was in place, he filled the trench back in.
The roads were restored.
The courtyards returned to normal.
Only the slightly different color of the soil betrayed that the ground had ever been disturbed.
Thus, the tablets at the Grand Theater and the marketplace square were successfully supplied with power.
After confirming that everything worked, Li Daoxuan paused, thought for a moment, and shifted his view again.
This time, he returned to Gao Family Village.
On a small hill beside the Gao Family Village commercial district, he erected another photovoltaic system.
That evening, as the sun slowly dipped below the horizon—
On the large screen outside Gao Family Fortress, the program "Shi Kefa Legal Education" was playing.
Workers who had finished their shifts sat neatly arranged in rows in the plaza, snacking, chatting, and learning about the law with surprising enthusiasm.
Meanwhile, on the small hill nearby—
Song Yingxing.
Bai Gongzi.
Wang Zheng.
Along with senior technical engineers, graduate students, middle school students, and a group of so-called "knowledge pioneers" who had long since graduated middle school and were self-studying high school curricula.
All of them stood together.
All of them looked up.
Above their heads loomed an immense photovoltaic system.
To Li Daoxuan, it was nothing more than a few metal frames and panels.
To the little people below, it was a divine construction of unimaginable scale, something no human hands could ever hope to move.
Song Yingxing pointed upward.
"Everyone, look carefully. These panels are the same type as those installed on our Solar Cars. The only difference is that Dao Xuan Tianzun has laid them out on a scale far beyond anything we imagined."
Bai Gongzi nodded vigorously.
"There's no doubt about it. This converts sunlight into electricity. We've studied electricity in our physics textbooks… but we've never actually used it."
Everyone nodded.
Through the Physics Heavenly Books bestowed by Dao Xuan Tianzun, they had already completed middle school physics, and some had even begun high-school level material.
They understood electricity.
They understood circuits.
They understood theory.
What they lacked was practice.
Song Yingxing's voice trembled slightly with excitement.
"This divine machine can provide electricity. That means everything we learned but couldn't test before… can finally be realized!"
Bai Gongzi grew animated.
"In third-year middle school physics, there was a chapter called How to Light a Lightbulb. I read it over and over, but without electricity, it was meaningless. Now we can finally try!"
Wang Zheng coughed lightly.
"Gentlemen… let us not rush. This is a divine artifact bestowed by Dao Xuan Tianzun. If we secretly draw power from it for experiments, might we anger him?"
Song Yingxing laughed.
"Old Wang, you arrived too late to Gao Family Village. You don't know Dao Xuan Tianzun's temperament. He is happiest when we study diligently."
Bai Gongzi nodded.
"Correct. Dao Xuan Tianzun praises us often. He has never scolded us."
Several older students chimed in at once:
"Just do it!"
"Stop hesitating!"
"This is knowledge!"
Wang Zheng clasped his hands together hurriedly.
"Amitābha, Immeasurable Good Fortune, Allāh Akbar, Hallelujah. This discussion has nothing to do with me. I didn't hear anything."
At that moment, Bai Gongzi—always the boldest—stepped forward.
"To draw electricity, we need a wire. Look at this thick cable. If we make our own wire as described in the physics textbook and connect it—"
"We'll have to cut the insulation."
"The insulation looks thick, but it's soft."
"Wait," someone said nervously, "if our knife touches the metal core… we'll get shocked."
"Getting shocked means death!"
A wave of alarm rippled through the crowd.
Song Yingxing raised his hand.
"Don't panic. All divine artifacts provided by Dao Xuan Tianzun share one characteristic."
"What is it?" several voices asked.
"They have a large switch."
The crowd froze.
Then erupted.
"Master Song has enlightened us!"
Everyone rushed toward the electrical box.
And sure enough—
There it was.
A massive switch.
On it were two words:
ON / OFF
Everyone fell silent.
"…We can't read this."
"What if pushing the wrong side causes disaster?"
"Perhaps one side means 'Ascend to Heaven' and the other means 'Vanquish Evil Spirits'."
At that moment, Wang Zheng burst out laughing.
"Hahahahaha! I can read this!"
Everyone turned.
"These are Western characters," Wang Zheng said proudly. "'On' means open. 'Off' means close."
The crowd exploded with joy.
"Old Wang is actually useful!"
"But why are there Western characters on a divine artifact?"
Wang Zheng explained solemnly,
"As I've said before, many divine artifacts are borrowed from other deities. This one may belong to Jesus or the Virgin Mary. Hence the Western script. At times like this, we should say—Hallelujah!"
"Get lost!"
Despite the ridicule, the crucial information had been delivered.
A graduate student climbed onto the box, raised a large hammer—
Clang!
He struck the OFF switch.
