Feng Lingtian spent the night in the valley. The next morning, he picked up the Master Token again, looked at it for a long time in the morning light, then put it down and picked up a new piece of silver-patterned ore.
"After careful examination last night, I realized that the exposed patterns aren't actually a problem—as long as the core inside remains incomprehensible to others when they disassemble it, it's fine."
Feng Lingtian reconstituted the wind blade and carved a new token using the same method as the Master Token token—injecting diluted essence, sprinkling with immortal Immortal Herb powder, sealing it, and closing the groove.
This time, however, he added an extra layer of treatment when sealing the opening, making the grooves fit more tightly. When forced open, the ore would break first from the area with the densest texture.
After finishing the last cut, he examined the Sub-Token in his palm, then handed it to the Blue Silver King: "Try it, see how it works."
Without hesitation, the Blue Silver King probed the surface of the Sub-Token with a pale blue Soul Power, gently applying pressure along the edge of the pattern.
A very faint cracking sound came from inside the ore—the token cracked at the densest branch of the pattern, and then the entire token shattered into several pieces. The pattern broke, and pale golden essence seeped out from the cracks and quickly dissipated into the air.
Feng Lingtian looked down at the fragments and said calmly, "Success. As long as we forcibly break it apart, the token will be destroyed, and no one will be able to see the core inside."
Feng Lingtian and then said, "By the way, I also thought of a question yesterday, about usage patterns."
To facilitate communication, I previously developed Resonance Stone and Communication Stone. They can only transmit vibrations and text, and the connection is easily lost if the distance is too far.
However, the Yu Feng Token developed this time uses the essence of Blue Silver Grass as a medium. Given that Blue Silver Grass cover the entire continent, its effects should be even greater.
I want to see if I can enable this token to transmit text, voice, and image simultaneously.
So Feng Lingtian gathered the fragments and put them aside, picked up a piece of silver-patterned ore, and began to refine the second Sub-Token.
This time, he didn't adjust the structure; he simply confirmed that the process was stable before continuing to carve, inject fines, and seal, quickly completing the second finished product.
Feng Lingtian placed the second Sub-Token in front of the Blue Silver King: "You keep this one. I'll take the Master Token far away and see how far we can increase the distance."
Holding the Master Token's Feng Lingtian strode out of the valley, through a dense forest, over two hillsides, and stopped in an open space outside a village.
He infused the Master Token with pure Soul Power and sent a message. A moment later, the Master Token received a reply; the words were clear and the message read: Received.
Feng Lingtian tried the voice mode again—he entered a sound into the Master Token, and after a few breaths, the returned message restored the outline of the sound. Although it was not clear, it was clear that it was the words "heard".
Finally, Feng Lingtian began testing the image mode. He infused the Master Token with Soul Power imbued with light and shadow, Master Token the patterns on its surface to illuminate, and light and shadow to rise from above the token, condensing into a small image.
One can see the village where Feng Lingtian is currently located, the rooftops in the distance, and the sky above. A moment later, a second layer of light and shadow appears on the Master Token, coming from the Blue Silver King's side:
Deep blue-green leaves of Blue Silver Grass, damp soil at the bottom of the valley, and soft sunlight.
Feng Lingtian tried to speak, and the Blue Silver King's voice came back from the Master Token: "I can see you."
Feng Lingtian held the Master Token for a moment, then said, "Text can be transmitted, voice can be heard, and images can communicate with each other. The distance is far enough; this experiment has been a success. I'll go back now."
Feng Lingtian put away the Master Token and turned to walk back. When he returned to the valley, the Blue Silver King was still in the same spot.
After Feng Lingtian returned, he picked up the third piece of silver-patterned ore and began carving again.
This time he carved more slowly than the previous two times, each cut was made very steadily, as if he were completing something that should not have any mistakes.
After the patterns are carved, the diluted essence is injected, sprinkled with Immortal Herb powder, sealed, and then the edges are trimmed.
Instead of shaping it into a token, Feng Lingtian carefully polished the ore into a ring, with fine patterns engraved on the inner wall and a smooth, flat exterior, as simple as a plain silver ring.
He added a few fine lines to the ring, resembling the outline of some kind of flower or leaf; they served no purpose, just for aesthetic purposes.
After polishing, he examined the ring several times to make sure there were no problems before putting it away in his pocket.
Watching his actions, the Blue Silver King couldn't help but ask, "This shape is different from the other tokens. Was it specially designed?"
Feng Lingtian didn't look up, deliberately keeping his tone calm. "Yes, it was designed for someone waiting for me to return."
"Your partner?"
"We're not officially partners yet," Feng Lingtian said, "But... it'll be soon."
The Blue Silver King didn't ask any more questions; the pale blue light simply flickered slightly, as if it were smiling.
Not wanting to be teased, Feng Lingtian didn't stop. He picked up the fourth, fifth, and sixth pieces of ore and engraved several token-shaped Sub-Token. His technique was so skilled that he didn't need to pause.
Each one was made with diluted essence, and each one had the same tamper-proof structure. He Sub-Token one by one beside him, and finally put them all away before standing up.
"I have the Master Token, I have the Sub-Token, the anti-tampering problem is solved, and the communication function is verified. I should go back now," Feng Lingtian said.
Blue Silver King didn't try to stop him. "When are you coming back?"
"I'll come back as soon as I've settled in," Feng Lingtian said. "I'll make preparations at the Ice and Fire Yin Yang Well. Once you get there, the entire Blue Silver Grass clan will benefit."
The Blue Silver King remained silent, and the pale blue light gradually dissipated.
Feng Lingtian glanced at the deep blue-green Blue Silver Grass, then turned and walked out the way he had come. The Blue Silver Grass parted to the sides in front of him, then closed up again after he passed.
As Feng Lingtian stepped out of the valley, the sunlight returned, making him squint.
Feng Lingtian paused at the valley entrance for a while, waiting for his eyes to adjust to the light, before retracing his steps.
He left that Blue Silver Forest behind.
