This stick of incense is quite long and can burn for about half an hour.

In half an hour, out of the thousands of raw stones in the entire square, it takes at least four stars to pick out a piece containing spiritual stones.

In order to pick out the raw stones containing spiritual stones, one has to use spiritual consciousness to scan them one by one. However, these raw stones have been processed and it is difficult for spiritual consciousness to penetrate them, which greatly increases the difficulty of selection.

However, using spiritual consciousness brings mental exhaustion, just like people will feel tired after reading for a long time. Spiritual consciousness cannot be used for a long time.

Some people have weak spiritual awareness, which can only be released for a few seconds. They have to rest after watching for a while, and time is limited. Unless they are lucky enough to choose a piece containing spiritual stone at once, the result is uncertain.

Xue Huan didn't feel much. Although her spiritual sense did feel some resistance when scanning those raw stones, this resistance was not strong compared to her spiritual sense. If her spiritual sense was a knife, then this resistance could only be regarded as a piece of paper at most.

It made little difference to her whether she had the paper or not.

Xue Huan released her spiritual sense and directly scanned all the raw stones within a radius of five meters. This was because there were people farther away, otherwise her scanning range could be larger.

She was lucky, as there happened to be spirit stones within the scanning range, and there were more than one.

There are three pieces in total. The spirit stone in the No. 1 raw stone is only as big as a chess piece, but it has a very high clarity and meets the standard of a mid-grade spirit stone. The No. 2 piece is as big as a teacup and is a low-grade spirit stone. The last piece is as big as a cantaloupe and is also low-grade.

Although Teacher Zeng said that you can pass the test by choosing the raw stone containing spiritual stones, I wonder if there will be any extra points for this test?

Xue Huan compared the three rough stones and finally chose number three, then walked towards that rough stone.

However, just as she was about to reach out and touch the raw stone, someone suddenly bumped into her. Although she dodged in time, another person took the opportunity to grab the raw stone in his hand.

These two were the two lackeys around Zhou Lekang. The lackey B who got the raw stone handed it to Zhou Lekang with a flattering look on his face.

Zhou Lekang took it and looked at the stone from front to back and up and down. When he saw a black mark somewhere, the corners of his mouth curled up and he smiled.

That smile was the smile of someone who was sure that he could get the spirit stone out of it.

Almost in an instant, Xue Huan understood the trick. Zhou Lekang was cheating!

In other words, someone helped Zhou Lekang cheat. That person knew the test questions in advance, so he marked the raw stone and told Zhou Lekang, so Zhou Lekang had someone take the raw stone away.

Xue Huan's first reaction was to expose Zhou Lekang, put a truth talisman on him, guide him to tell the truth, and expose herself. But then she thought it was not appropriate. If she did that, Zhou Lekang would definitely bear a grudge against her.

The previous matter is not over yet. If the Zhou family finds out about her, she will be alone and might be ambushed by the Zhou family.

The Zhou family can extend their influence into the college, which means that their power has already penetrated the college. If the Zhou family members target her specifically, it will definitely be very troublesome and detrimental to her plan.

The plan was aborted before it even started because of the Zhou family's targeting.

She should keep a low profile and develop slowly now.

Therefore, it is not advisable to confront Zhou Lekang head-on.

If that's the case, then let's do it secretly.

Xue Huan pointed at Zhou Lekang angrily, "What are you doing? I was the first one to see this rough stone. What gives you the right to snatch it away?"

"Oh, you saw it first? Who can prove it? I said I saw it first." Zhou Lekang said sarcastically.

Dog Leg Armor: "That's right, it was obviously Master Zhou who took a fancy to this rough stone first!"

Latch Second: "There's no name written on the stone. It's in Master Zhou's hands, so it belongs to Master Zhou."

Xue Huan glared at the three of them, too angry to speak. She could only watch Zhou Lekang leave triumphantly with the stone in his arms.

Wang Qiubai, who was not far away, saw this scene and gloated. For some reason, she felt disgusted when she saw that woman and wished she would be in trouble.

Zhou Lekang held the stone and walked towards the place where the stone was to be cut. What he didn't notice was that the small stone with the invisibility talisman on it had approached the stone in his hand and slowly drilled into it, or to be more precise, merged into it.

The small stone is a stone spirit that can blend into any stone silently like a drop of water falling into a lake. Once it blends into the stone, it can easily find the spiritual stone inside and eat it into its stomach with a crunch.

"How did he choose so quickly? The incense isn't even halfway burned yet."

"He looks so confident. That piece of raw stone must contain spiritual stones. I'm so envious."

"Hey, I have to speed up, otherwise I will be eliminated."

Facing the envious, jealous and hateful eyes of the crowd, Zhou Lekang enjoyed it very much and his face became more and more proud.

"Untie this stone for me." He said to the old man in charge of untie the stone in a very impolite tone, as if he was talking to his own servant.

The old man pointed to his ears and said, "What did you say? Speak louder. I can't hear you."

Zhou Lekang repeated it unhappily.

The old man said, "You want to cut the stone yourself? Oh, you can choose the tools yourself."

Zhou Lekang's eyes turned sinister, "Old man, you are deliberately teasing me!"

If he hadn't remembered that this was Lingyao Academy, not a place where he could act wildly, he would have been unable to resist beating up the old man.

The old man said, "Are you kidding me? Tell me clearly, why are you kidding me, an old man?"

He grabbed Zhou Lekang's collar with unexpectedly strong force, and no matter how hard Zhou Lekang tried, he couldn't break free.

Zhou Lekang's neck was stuck, and he had difficulty breathing. He couldn't hold it in any longer: "You old fool, let me go... cough cough!"

This time the old man heard it clearly, "You called me an old man? Oh, young people nowadays really don't know how to respect the elderly."

The hand that was holding Zhou Lekang's collar suddenly loosened. Zhou Lekang, who was struggling hard, lost his balance, fell out, and sat down on the ground.

As luck would have it, there was a sharp stone on the ground, which happened to poke it.

Zhou Lekang jumped up in pain like a monkey, holding his buttocks, his face twisted in pain.

The old man looked at him with a smile: "Do you want to break the stone again?"

Zhou Lekang squeezed out a word from between his teeth: "Solve!"

The old man skillfully cut open the raw stone with smooth movements. Although it was a boring job, when he did it, it was full of leisurely rhythm and beauty.

However, Zhou Lekang could not appreciate that kind of beauty. He only felt hatred in his heart, hatred for the old man.

The stone was opened, and there was nothing but stone, not even a trace of spiritual stone residue.

Zhou Lekang took a look and blurted out: "Where is the spirit stone!"

His tone was one of shock and confusion, not disappointment, as if he had known there were spirit stones inside.

The old man looked at him deeply and spread out his hands: "What spiritual stones? There are no spiritual stones here at all!"

Zhou Lekang: "Impossible, I clearly...used my spiritual sense to detect that there were spirit stones inside. Did you secretly swap my original stones?!"
