The consumption of the canteen is very high, and the average student from the viscount and earl family can only come here once in a while to satisfy his appetite, and a simple meal will cost at least one lower grade spirit stone, which is hundreds or thousands of times more expensive than the restaurant consumed by ordinary people in the outside world.

As the top three forces in the Refining Saint Tower, the Wasteland Reclamation Group took the top floor of the entire dining hall and held a banquet, which fully reflected the heroic spirit of the top three forces.

It was noon, and the sun was shining in the sky, and wisps of scorching sunlight were shining on the earth and burning people's skin.

Yin Lan carried a heavy black bag and came to the top floor of the dining hall, looking around, there were four or five exquisite tables made of ice crystal cold jade, and beside each table, there were already many members of the Wasteland Reclamation Group.

At the table in the center, the atmosphere was the most enthusiastic, and the person in the first seat was a handsome young man, with long black hair tied up, and two strands of long hair hanging down his cheeks at the sideburns, with a dashing bearing, and a faint gentle smile on his face.

And on the silver round badge on his chest, there are five stars, indicating that this is a rare five-star student!

"He should be the head of the Wasteland Reclamation Regiment, Xiao Changqing. Yin Lan looked at the handsome young man and secretly confirmed the identity of the other party.

The cultivation of the ninth-level spiritual cultivator, coupled with the identity of a five-star student, is located in the first seat, this handsome young man is naturally Xiao Changqing, the head of the Wasteland Reclamation Regiment who left the Refining Saint Tower a year ago and went to practice outside the territory.

Xiu Fan and the other deputy heads of the wasteland reclamation regiment sat next to the handsome young man, after seeing Yin Lan come to the top floor. Xiufan, who had long purple hair, shouted to Yin Lan, "Come and sit here!"

Yin Lan is a core member of the reclamation group. Naturally, he was qualified to sit at this table, so he walked over.

"I've seen Captain Xiao. Yin Lan walked over. Before anyone else reminded him, he directly greeted the handsome young man.

"You're welcome, just sit down. Xiao Changqing smiled at Yin Lan, his tone was gentle, and then, he took out a square exquisite white jade box from his arms and looked at Yin Lan, who had already sat down: "I heard from several deputy heads that you want to destroy the source stone, and it just so happens that I am outside the territory." I bought it after I came across it, and this is it. ”

Xiao Changqing said, and put the white jade box on the table in front of him.

"Thank you Captain Xiao for your help!" Yin Lan thanked him, looking at the white jade box, his expression was calm, but his heart was hot.

Then, Yin Lan took off the big black bag he was carrying from his back. put it on the table and said, "Captain Xiao, this is two hundred and fifty top-grade spirit stones, please accept it." ”

Others at the table. They all smacked their tongues secretly, two hundred and fifty top-grade spirit stones, that is, two hundred and fifty thousand low-grade spirit stones. With such a fortune, except for Xiao Changqing, who has a terrifying family background, there are people here. Only this Yin Lan in front of him can be taken out!

"Yin Lan, don't worry. Destroying Source Stones is a forbidden item. The killing range is extremely wide, can you tell me why you need to destroy the source stone?" Xiao Changqing did not give the things to Yin Lan immediately, but stared at Yin Lan's eyes, and his tone was slightly serious.

Without thinking, Yin Lan replied, "In order to study the reaction agent." ”

"Reactors?" the others were intrigued by this statement.

"Captain Xiao, all the deputy heads, and all the core members, I think everyone knows about my promotion to a four-star student, and it is true that it is precisely because I contributed to the Holy Tower a reaction agent formula that I researched by accident. ”

This is naturally the rhetoric that Yin Lan prepared, and with the fact that he was suddenly rewarded with a large number of points by the Holy Tower and promoted to a four-star student as a foreshadowing, this reason did not seem abrupt at all.

Wow!

Many of the people present were suddenly stunned.

All the students who were within the scope of the Refining Saint Tower had received the announcement that Yin Lan had been promoted to a four-star student, but no one knew how Yin Lan was promoted, and Yin Lan had not revealed the slightest, which made people very curious.

Now, they finally know why.

"A self-created reactant formula has been directly promoted to a four-star student, and at least seven or eight hundred points have been obtained, what kind of reactant is it that is so valuable?"

"No wonder Yin Lan can take out so many top-grade spirit stones, I'm afraid they were rewarded by the Holy Tower. ”

"Tsk, it's really good luck that he has created a reaction agent that can be exchanged for a large number of points! But this kind of good thing is already rare, this Yin Lan wants to do it again, and he is ready to use the destruction of the source stone as the research direction, this ambition is inevitably too great. ”

Whether it was the members of the reclamation group at the central table or the members of the reclamation regiment at the surrounding tables, they all secretly discussed or sighed in their hearts.

But Yin Lan's doubts about wanting to destroy the source stone have also been reduced a lot.

Xiao Changqing stared at Yin Lan, the expression on his face was still gentle, but in the depths of his eyes, there was a trace of doubt, he always felt that Yin Lan's reason for wanting to destroy the source stone was not so simple.

However, since he returned to the Dahua Kingdom from outside the territory and purchased the destruction source stone that Yin Lan needed, he naturally would not let this thing rot in his hands, after all, in addition to the high danger, the destruction of the source stone is not very useful.

The reason why I asked Yin Lan was just out of curiosity.

Small courtyard, inside the attic.

After Yin Lan entered the room, the topaz doll Changsheng, who had been obediently staying in the room, hurriedly ran to Yin Lan and jumped onto Yin Lan's shoulder at once.

"Changsheng, I'll show you something good. In his own private space, only Changsheng, who had signed an equal contract, was accompanied, and Yin Lan finally did not suppress his emotions, and his face was full of excitement.

Destroy the source stone, finally get it!

Under the gaze of Changsheng tilting his head and his big eyes full of curiosity, Yin Lan took out a white jade box from his arms and opened it slowly and carefully.

Rumble!

As the white jade box slowly opened, the light shone brightly, and a destructive aura full of destructive power emitted strongly, making people's souls feel a suffocating sense of apocalypse, as if they were in a murderous and violent hell.

"Ahhh

If it weren't for Yin Lan's previous life, he had learned the power of this kind of thing, I am afraid that after feeling the aura of destroying the source stone, he would be so frightened that he hurriedly threw it away.

"With this thing, I will soon be able to break through to the realm of spiritual cultivators!" Yin Lan muttered in his heart as he stared at the light that slowly dissipated, revealing a square crystal as black as the devil's eyes.

This square black crystal, the size of a goose egg, feels thrilling at a glance, the soul trembles, and the breath makes the heart palpitate.

In this era, most people's understanding of the destruction source stone only stays at its ability to cause great destructive power, and no one has deeply explored its role.

Many people only know that once the destruction source stone is triggered, a huge suction vortex will be generated in an instant, forming a black hole, and frantically absorbing the aura of heaven and earth.

As the more heaven and earth aura is absorbed, the black hole will also expand, and when it expands to the limit, it will completely collapse, and that kind of destructive power is enough to make chickens and dogs not stay within a radius of thousands of miles!

It was not alarmist that it was able to destroy a small county like Qinglan Kingdom.

Of course, generally speaking, no one will use this thing in normal national warfare, this is an unspoken rule, and countries large and small on the Shanlan Continent tacitly follow such a rule.

Basically, it is a treasure used to carry out extraterritorial reclamation, such as encountering some obstacles that are difficult to break through and prevent the progress of wilderness reclamation, it will be solved by destroying the source stone.

However, this method of using the destruction of the source stone, in Yin Lan's opinion, was the lowest!

With Yin Lan's experience and knowledge in his previous life, the Destruction Source Stone could be used for high-level refining products such as spiritual power cannons, spiritual power warships, and fixed space teleportation arrays, and they were all one of the important materials for those refining products.

Of course, Yin Lan bought this destruction source stone, naturally not to refine those high-grade refining products, now he doesn't have the strength and capital, he is using it to improve his cultivation.

This kind of usage is a kind of "crooked and evil way" that Yin Lan had heard of in his previous life, that is, to use the destruction of the source stone to devour a huge amount of spiritual energy to form a black hole, and then, using a unique secret technique, the violent spiritual energy that formed the black hole was incorporated into the sea of qi to cultivate......!
