This night, Xiu Yin could no longer continue to study the mysterious red stone, because "he" did not have the habit of going to bed late, so in order not to let his family doubt him, Xiu Yin had to hold back his strong curiosity until the next day.

After a night of sleep, Xiu Yin told Iana that she wouldn't eat breakfast today if she didn't have a good appetite.

Quietly locking the door like a thief, Xiu Yin couldn't wait to pour the mysterious red stone out of the water bag.

The early morning sun shines through the window of the room, which is facing the east, and this is the time when the sun is at its fullest.

Picking up the mysterious stone that had taken Xiuin a lot of effort, Xiuin squinted at the stone in the sunlight.

Under the reflection of sunlight, the viscous liquid in the crystal-like redstone seems to be more pronounced.

But Xiu Yin held the stone in the morning sun and looked up for a long time, but he did not notice any change in the mysterious stone, but his eyes were a little tired to see.

Unable to hold back the pain in his eyes any longer, the moment Xiu Yin took the red stone from front of his eyes, when Xiu Yin's left eye was directly aligned with the sun, a piercing sensation hit Xiu Yin's brain.

"Whew!"

Xiu Yin staggered back a few steps, a pained expression on his face, and he quickly covered his left eye with his left hand.

The pain came very suddenly, and the pain came from within, and it felt as if his brain had been hit hard in an instant, and all the pain was concentrated in a single spot in his left eye.

This is not the first time Xiuin has experienced this feeling, a few days ago, when Xiuin and Bill and Jack were about to go to the mining area together, as soon as he left the gate of the mansion, Xiuyin experienced a sudden pain in his left eye, and it was after that that he noticed that when he picked up the crossbow, there was a green crosshair in the center of his vision.

Only this time the pain in his left eye was even stronger than the last time, and Xiu Yin couldn't even help but shed a large number of tears in pain.

"Whew, what's wrong with these eyes, but don't break them!"

Xiu Yin can continue to bear the pain, but what he fears most is that the "Silver Pupil" will malfunction. After discovering the aiming function brought by the "Silver Pupil", Xiu Yin was already full of confidence in surviving in another world.

Especially after seeing the archer in battle last night, Xiu Yin thought that he really couldn't go on the path of a mage, at least he had the aim assistance of the "Silver Pupil", and he believed that with this skill, he could also make some fame in the other world.

At the same time, Xiu Yin was worried, and the pain began to gradually subside, and finally when the pain disappeared completely, Xiu Yin hurriedly let go of his left hand, opened his left eye, which was still full of tears, and looked out the window.

The morning light was still so soft, and the sky above Lystar Fort still had a beautiful blue, the color of the sky that was no longer visible in his previous world.

"Whew-"

Xiuin let out a long sigh of relief, his mood relaxed, and his eyes could still see the charming blue sky, and wiped the tears from his face with the back of his right hand and wiped it on his pants.

But at this time, Xiu Yin noticed that something was wrong, and there was an extra line of small green words in the lower left corner of his vision!

【System Charging...... 73%】

"Crossed his knee, what is this!"

Xiu Yin exclaimed, he didn't understand what this meant, this was also a subtitle that had not appeared before, and the "Silver Pupil" would only show subtitles on the field of view when it was first activated......

However, not long after Xiuyin's exclamation, Ianna's voice came from outside the door, "Young Master Xiuyin, what's wrong with you?" There was some worry in his voice.

This was followed by the sound of pushing the doorknob, but the door had been locked by Xiu Yin, and Ianna couldn't get in.

In order not to make Iana suspicious, Xiu Yin hurriedly went to open the door, but he still had a mysterious red stone in his right hand, so he stuffed it directly into his trouser pocket.

"Ianna?" said Xiu in surprise, pretending to be confused as he opened the door.

"Young Master, you just shouted!" Ianna said as she stretched out her head and glanced around Xiuin's room.

"Oh, nothing, it's just that I'm reading a book about magic and I've discovered a lot of things I didn't know before. A smile appeared on Xiuyin's face, in fact, he had a very good impression of Ianna, after all, people really cared about him.

However, there seemed to be something wrong with Ianna's expression, especially when Xiu Yin noticed that her gaze swept to her lower body, and her face became ugly again.

"Then young master, just continue to read, I won't bother. ”

The whispered words that Iana muttered as she turned to leave were heard again by Xiuyin, "Hmph, it's definitely not a good book......

Xiu Yin hurriedly lowered his head, although this time it was not as unbiased as the last time, but this time there was still a water mark near the important area of his pants!

And the most important thing is that on the water mark, there is also a bulge that looks like a big, stiff fabric that looks like a mushroom head through the pants!

"Crossed his knee, and there were tears, tears, and, and this is the stone in my pocket, the stone......"

Of course, Xiuyin's inner cry was inaudible to Ianna, who had already walked down the stairs.

"Over, this friendship must have dropped again!" Xiu Yin suddenly remembered the text adventure game he had played on the console in the original world, and if the friendship with the female characters in the game was too low, there would be many things that he would not be able to do!

"Forget it, I didn't want to do anything more......" Xiuin shook his head and locked the door again.

The green text in the lower left corner of the field of vision is still there, but it still reads: [System Charging...... 73%】。

"Could this number be the remaining power of the 'Silver Pupil'?"

After receiving the implantation of the "Silver Pupil", Xiu Yin received a thick instruction manual, and was told to read it carefully, so Xiu Yin clearly remembered that the energy source of the "Silver Pupil" was from solar charging, which would automatically store electricity during the day when there was sunlight, and only need 12 hours of charging to use it continuously for 24 hours.

"Could it be that the pain in the eyes has something to do with the recharge of the silver pupils?"

Xiu Yin recalled the pain in his eyes when he first went out, and it was true that he had been stuffed in the mansion for a long time, and he could only bask in the sun for a short time in the morning every day, maybe it was because of the lack of energy in the "silver pupils" caused by this?

But this time the pain made him unable to think of the reason, because he was out of the house these days, and spent almost a lot of time in the mine.

Finally, with the heart of trying, Xiu Yin walked to the window again, raised his head, and let the gentle morning sun pour on his face again.

"Whew!"

There was another tingling sensation, but it was much lighter than the previous two times, but the pain still had that sudden feeling.

At this time, the lower left corner of Xiuin's field of vision reads: [System Charging...... 87%】
