Only after unifying the world did I realize that immortals existed in this world.

"Did it work?"

Xie Cangrong lowered his eyes and looked at the girl sitting in the wheelchair in front of him.

"right!"

The girl hadn't rested in a long time, and even with her extraordinary power, she didn't look too well. But her eyes were bright and her spirit was high. She said to Xie Cangrong, "I have deciphered Lu Junfeng's method for mining spirit ore and gathering spirit."

"I can use mechanical power to replicate and modify, and we can now mine spirit ore independently."

"Unfortunately, some of the spell runes are still obscure. If a cultivator could provide annotations, the effect of gathering spirits could be further improved..."

In less than a month, with little intelligence, Gong Qiao managed to master the technology of spirit mine mining by relying on Lu Junfeng's few words and on-site investigation of the spirit gathering array.

Xie Cangrong knew very well what this meant.

This is the first step in breaking the monopoly of monks on technology.

The girl he raised was a genius.

"Good! Good! Good!"

He smiled, his eyes brimming with barely suppressed joy: "My Gong Qiao never disappoints."

He knew what Gong Qiao most wanted to hear at that moment.

He needs to express his joy, praise, and affirmation.

Showing concern, asking questions, reminding her to take care of her health and get some rest... these things should come later.

Xie Cangrong's words are enough.

Gong Qiao looked up at him and saw her own reflection in his eyes. A faint smile appeared on her lips: "I won't let 'you' down."

Xie Cangrong's promise was that she wouldn't need to engage in intrigue, politics, or worry about anything other than research...

Her promise was that as long as Xie Cangrong ensured her safety and created the conditions for her, she would do her best to achieve all of Xie Cangrong's goals.

They are all fulfilling their promises.

"And~"

This is not over yet!

Gong Qiao then took out two jade stones from her bosom, giving one to Xie Cangrong and keeping the other in her own hand.

These are spirit stones produced in the Great Xia Dynasty.

She then gently patted the armrest of her wheelchair, and a short wooden stick automatically popped out from under the armrest. She held the stick and gently tapped the spirit stone in her hand.

The two spirit stones immediately reacted and emitted a brilliant light.

She tapped it once, and the spirit stone lit up.

She looked up at Xie Cangrong: "The power of ingenuity allows me to see the fixed patterns in the internal structure of this spirit stone. By using the power of ingenuity to carve according to these patterns, some changes will occur, stimulating the energy within... I guess the talismans made by cultivators may be related to this."

The usually quiet girl was now talking non-stop about her research findings and conjectures, telling Xie Cangrong everything, regardless of whether he could understand her or not.

She is not good at expressing emotions or engaging in casual conversation, but she is very good at expressing objective facts about her discoveries in her professional field.

Xie Cangrong narrowed his eyes upon hearing this: "Oh?"

Spirit stones are indeed good things.

During my conversation with Chu Xiangyun, we touched on talismans a few times, but such casual conversations naturally didn't go into depth. I simply said that cultivators use their magical power as a pen to imprint magical runes onto spirit stones, creating talismans based on various secret techniques and incantations passed down through generations, to achieve various functions such as activating spells, providing protection, etc.

They seem to rigidly follow the passed-down experience and secret methods to make talismans, as if they have no concept of the internal structure of the spirit stone.

Gong Qiao's discovery and explanation seem to be closer to the essence of the spirit stone.

Is this Gong Qiao's power characteristic?

If they have the chance in the future, he and Liu Bingxuan will test those people again.

Gong Qiao had no idea what Xie Cangrong was thinking. He simply picked up the spirit stone in his hand, shook the small wooden stick, and said to Xie Cangrong, "I've discovered that if you cut the same spirit stone along its veins at a reasonable location, it won't be damaged. There's a connection between two spirit stones. If you then use this wooden stick, which has been enhanced with the power of ingenuity, to strike the cut surface and establish a flow, it will trigger a resonance between the two spirit stones. This reaction can overcome the limitations of extremely long distances."

"The limits are still unknown. I have ordered people to test it outside the city, and it should be successful."

A small stone contains enormous energy, and this energy, if properly guided, can accomplish many things and unleash infinite possibilities.

"There are too many secrets in this spirit stone. I want to continue to study it in this direction. Sooner or later, I will be able to send messages and find a way to communicate remotely."

Gong Qiao would do her best to help Xie Cangrong achieve whatever he wanted.

She didn't mention the lighting function that she'd accidentally discovered. The real purpose of taking out the two spirit stones was simply to tell him that there was progress on the remote communication matter Xie Cangrong had asked her to handle.

Da Xia once told Xie Cangrong that telephone research had stalled and faced many insurmountable difficulties.

Although the direction is definitely right, it's just that we can't seem to get it working.

After obtaining the spirit stone, inspired by Xie Cangrong, Gong Qiao abandoned the originally planned development path, changed her approach, and used the spirit stone to suddenly make a discovery, achieving a breakthrough.

This is simpler and easier than developing a phone.

The two spirit stones can react despite geographical limitations. If she continues her research and overcomes the difficulties of sound or writing, she can achieve information transmission.

Xie Cangrong looked at the glowing stone in his hand, then at the woman before him, and shook his head and sighed softly, "There is no one in the world more intelligent than my Gong Qiao."

The light from the spirit stone is very bright; perhaps in the future, this light can be used to illuminate the darkness of the Great Xia Dynasty.

But the girl in front of him was even more dazzling and radiant.

He stepped forward, took the wooden stick and stone from Gong Qiao's hand, and said to her, "We can now use these to send messages."

Gong Qiao paused for a moment, seemingly not quite understanding: "Huh?"

"Look."

He lightly touched the spirit stones with the wooden stick and immediately released it, and the two spirit stones immediately shone brightly for a moment.

Then the wooden stick was stuck to the spirit stones for a long time before being released, and the two spirit stones lit up for a long time before going out.

"By combining short highlights, long highlights, and pauses in different orders, can't we piece together information?"

Gong Qiao is so clever!

She was just too focused on transmitting messages. After Xie Cangrong's reminder, she paused briefly, then instantly realized: "Yes! Yes! Yes!"

Her eyes lit up, and she said, "As long as we have someone compile a secret report, we can communicate!"

Xie Cangrong played this game with her when they were little.

I've been out of my mind lately and genuinely forgot.

Xie Cangrong knelt down to meet her gaze, staring intently at her: "Therefore, there is no one in the world more intelligent than my Gong Qiao!"

"I'm so lucky."
