Wood stood there, watching Professor Shivara busy for a long time, and he didn't know what kind of experiment Professor Shivara was doing, it looked very complicated. After a long time, seeing that the sun was about to set in the west, Professor Shivara smiled with satisfaction, and it seemed that the experiment had succeeded.

"I've been waiting. Professor Shivala looked at Wood and gave Wood, who had been waiting all afternoon, three words to explain.

"Drop the potion in your hand into it. Professor Shivala instructed that this was the final step of the experiment, and that it would be successful with just one drop.

"Me?" Wood asked, uncertain, the experiment seemed important, and Wood didn't feel qualified to take this final step.

"Don't you dare?" Professor Shivara smiled, looking at him, it seemed as if everything had gone through the past, as if it had never happened.

Wood picked up the potion in his hand, and since Professor Shivara had said it all, Wood had no reason to refuse. So, Wood calmly walked over, first sucked up some of the potion with a straw, and then tried to drip the potion into the test bottle.

Originally, the liquid in the test bottle was transparent, but when Wood dropped the drop, the clear liquid gradually decreased, and finally condensed into a small drop. This consists of a large bottle of liquid condensed into a small drop, and under Wood's gaze, begins to change its color. Yellow, blue, green, and finally red. The bright red color was like the bright red blood on Wood's neck.

"This is the tear stone, and the liquid you just saw is not famous, but it is actually the tears of some different species. Professor Shivara said as he poured out the tearstone from the bottom of the bottle and placed it in Wood's palm.

Tearstone is so hard that you can't tell that it's made of so much liquid. Wood looked at the tear stone repeatedly, and his heart began to feel sad inexplicably, and soon, Wood's tears were like beads with broken threads, which kept falling and couldn't stop.

"It has the power to make people sad, and everyone who comes near it will cry with sadness. The more tears it collects, the more powerful its magic becomes, and if it is used on the battlefield, it can be a lethal weapon to catalyze opponents. But this thing has a drawback, that is, whoever comes close to it will be affected by its own magic. Professor Shivara explained that Wood didn't understand why he had told him so much about tearstones. Although Wood didn't think it had anything to do with him, he didn't bother Professor Shivara.

"In this world, many things are reversed, and tearstones are like this. If a person's grief is higher than its grief power, it can change interestingly. At this point, Professor Shivala looked at Wood, and saw that he was very calm, and then said:

"When that happens, the tearstone changes its personality, and it tries to make that person happy, happy. Because its power is contagious, when it changes its mood, everyone around it will become happy and happy with it. However, these dry cooking happen at the time when people don't know it, so people don't thank Tearstone for it, and they don't know what Tearstone has done for them. With that, Professor Shivara took the tearstone back from Wood's hand and placed it in a small bottle.

The bottle was small, just big enough to fit the tearstone, as if it were made for the tearstone. Wood knew that this would not be difficult for Professor Shivara, but Wood became curious about the vial.

"Is this bottle a way to isolate it from the outside world?" Wood asked.

"You're right, this bottle is made of a special material, which I specially used to preserve the tearstones. Professor Shivara looked at Wood and said very seriously, the tearstone in his hand emitting a dazzling dawn in the light refracted by the bottle.

"It's so beautiful!" The blood-red tearstone is full of a dazzling light, it seems to have some kind of magic, so that people's eyes unconsciously stay on its body, unable to move.

"I gave it to you. Professor Shivara said it lightly, and his words made Wood shake violently.

"You're saying you're going to give me the Tearstone?" Wood said as if in a dream, not believing that Professor Shivara had really said that.

"Didn't you just say it's beautiful, this thing has no use for me at all, so I'm giving it to you. Professor Shivala spoke lightly, but Wood was a little apprehensive.

"Why?" Wood didn't know why Professor Shivara was so unusual today.

"Because...... Your mother, since you like this thing, I'll take it as a favor. Professor Shivala said of Wood's mother, a look of relief on his face.

"Do you know my mother?" As soon as Wood said this, he knew that he was really asking a hypocritical question, and sure enough, Professor Shivala's smile deepened when he heard Wood's question.

"You have to ask, in the whole wizarding world, who doesn't know your mother Lilia's. She's a well-known person in the wizarding world, so why don't I know her? Not only do I know her, but I often hang out with your mother, and we can't be said to be very good friends, but we do have a good relationship. At that time, Lilia was fifteen years old and Shivara was eighteen, and although the two of them didn't often play together, they were the kind of people who knew each other's thoughts without saying too much when they met.

Lilia used to call Brother Shivala, because in Lilia's mind, she always longed for a brother who could talk to her. And Sivara at that time was Lilia's yearning for her brother.

"Although your mother is criticized by everyone now, please believe me, I have always believed in your mother. It's just that...... Your mother came and went so suddenly that she didn't leave any clues for us, and even if we tried to help her, there was no evidence of her innocence. Professor Shivala regretted this.

This was the first time Wood had seen Professor Shivara confide in him, and it was related to his mother. I was very touched in my heart, Professor Shivara was like a mystery to Wood now. The more he expressed his inner thoughts to Wood, the more confused Wood became.
