The consumption of the kitchen hall is very high. Generally, students from the Viscount and Earl family can only come here to consume once a while to satisfy their appetite. For a simple meal, you will need to spend at least a low-grade spirit stone, which is hundreds or thousands of times more expensive than restaurants consumed by ordinary people from outside.￥f

As the top three forces in the weapon refining holy tower, the land reclamation group booked the top floor of the entire kitchen hall and held a banquet, which fully reflected the heroism of the top three forces.

It was noon at this moment, and the sun was shining brightly in the sky, and wisps of hot sunlight shone on the earth, burning people's skin.

Yin Lan carried a heavy black bag on his back and came to the top floor of the kitchen hall. Looking around, there were four or five exquisite tables made of ice crystal cold jade on it. There were already many members of the land reclamation group sitting next to each table.

On the table at the center, the atmosphere was the warmest. The person in the first seat was a handsome young man with long black hair tied up, and two strands of long hair on his temples were hanging down against his cheeks. He was graceful and had a faint gentle smile on his face.

There are five stars on the silver round badge on his chest, which means that this is a rare five-star student!

"He should be the chief leader of the land reclamation group, Xiao Changqing." Yin Lan looked at the handsome young man and secretly confirmed the other party's identity.

The cultivation level of a level ninth spiritual monk and the identity of a five-star student are also located in the first place. This handsome young man is naturally Xiao Changqing, the leader of the land reclamation group who left the holy tower of weapon refining a year ago and went to the outside world to experience it.

Xiu Fan and other deputy heads of the land reclamation troupe were sitting next to the handsome young man. After seeing Yin Lan come to the top floor, Xiu Fan, with long purple hair, shouted to Yin Lan: "Come here to sit!"

As a core member of the land reclamation group, Yin Lan naturally had the qualifications to sit at this table, so he walked over.

"I have met Captain Xiao." Yin Lan walked over. Before anyone could remind him, he directly greeted the handsome young man.

"You don't have to be polite, sit down." Xiao Changqing smiled slightly 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 commanders that you want to destroy the source stone, and I happened to be outside the domain. After I met it, I bought it, and it was this."

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

"Thank you, Captain Xiao for your help!" Yin Lan bowed and thanked her, looking at Bai Yu Box, with a calm expression, but her heart became hot.

Then, Yin Lan took off the black bag he was carrying from behind and placed it on the table, saying, "Captain Xiao, these are two hundred and fifty top-quality spirit stones, please accept it."

The others on the table were all secretly stuttering, two hundred and fifty top-grade spirit stones, or 250,000 low-grade spirit stones. Apart from Xiao Changqing, who had a terrifying family background, only Yin Lan in front of him could take out such a wealth!

"Yin Lan, don't be anxious first. Destruction of the source stone is a forbidden object. The range of killing is very wide. Can you tell me why the source stone needs to be destroyed?" Xiao Changqing did not give Yin Lan immediately, but stared at Yin Lan's eyes, his tone slightly serious.

Yin Lan replied without hesitation: "To study the reactants."

"Reactant?" Everyone else was curious by this statement.

"Captain Xiao, the deputy commanders, and the core members, I believe everyone knows that I was promoted to a four-star student. It is to be honest that I contributed a recipe for reactant that I accidentally developed to the Holy Tower."

This is naturally the argument that Yin Lan prepared. With the sudden reward of a large number of points by the Holy Tower and being promoted to a four-star student, this reason does not seem abrupt at all.

Wow!

Many people here suddenly realized.

All students within the scope of the weapon refining holy tower received a notice that Yin Lan was promoted to a four-star student, but no one knew how Yin Lan was promoted. Yin Lan had not disclosed the slightest, which made people very curious.

Now, they finally know why.

"A self-created reactant formula has been directly promoted to four-star students and has received at least seven or eight hundred points. What kind of reactant is it? What value is it so huge?"

"No wonder Yin Lan can bring out so many top-quality spirit stones, I'm afraid it's rewarded by the Holy Tower."

"Tsk tsk, I'm so lucky. I actually created a reactant that can be exchanged for a large number of points! However, this kind of good thing is rare once. Yin Lan wants to do it again, and is planning to use the destruction of the source stone as the research direction. This ambition is too great."

Whether the members of the central bank's land reclamation group or the members of the land reclamation group who were around, they all secretly discussed or sighed in their hearts.

However, the doubts about Yin Lan's desire to destroy the Source Stone have also been reduced a lot.

Xiao Changqing stared at Yin Lan, her face still had a gentle expression, but there was a hint of doubt in her eyes. He always felt that the reason why Yin Lan wanted to destroy the Source Stone was not that simple.

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

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

Small courtyard, in the attic.

After Yin Lan entered the room, Changsheng, the yellow jade baby who had been staying obediently in the room, hurriedly rushed towards Yin Lan and jumped onto Yin Lan's shoulder.

"Changsheng, let me show you something good." In his private space, only Changsheng, who had signed an equal contract, was accompanying him. Yin Lan finally did not suppress his emotions, and his face was full of excitement.

The destruction source stone was finally obtained!

With Changsheng tilting his head and curious eyes in his big eyes, Yin Lan took out a white jade box from his arms and slowly opened it carefully.

boom!

As the white jade box slowly opened, the light spread out loud, and a destructive aura of destructive power was strongly emitted, making the soul feel a suffocating sense of doomsday, as if it was in a violent hell filled with murderous intent.

"Ah!" Changsheng felt this breath and was so scared that he covered his face and quickly penetrated behind Yin Lan.

If Yin Lan had not experienced the power of such things in his previous life, he would have been so scared that he would have thrown away after feeling the aura of the destruction source stone.

"With this thing, I will be able to break through to the realm of a spiritual monk!" Yin Lan stared at the light slowly dissipated, revealing a square crystal that was as black as the eyes of the devil, and murmured in his heart.

This square black crystal is the size of a goose egg. It feels thrilling at a glance, the soul trembles, and the breath makes people feel palpitations.

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

Many people only know that once the destruction source stone is activated, an extremely huge suction vortex will be generated instantly, forming a black hole, and madly absorbing the spiritual energy of heaven and earth.

As the more spiritual energy is absorbed in heaven and earth, the black hole will also expand. When it expands to its limit, it will completely collapse. That destructive power is enough to keep a chicken or a dog within a radius of thousands of miles!

It is by no means an exaggeration to destroy a small county like Qinglan Kingdom.

Of course, generally speaking, no one will use this thing in normal national wars. This is a latent rule. All countries of all sizes and big and small follow such rules tacitly.

Basically, it is a treasure used for out-of-domain land renovation. For example, when encountering some difficult obstacles that are difficult to break through and prevent the progress of land renovation, it will use the destruction source stone to solve the problem.

However, in Yin Lan's view, this method of using the source stone is the lowest level!

With Yin Lan's experience and knowledge in his previous life, the destruction source stone can be used for advanced refining products such as spiritual cannons, spiritual warships, fixed space teleportation arrays, and are all one of the important materials for those refining products.

Of course, Yin Lan bought this destruction source stone not to refine those advanced refining products. Now he does not have the strength or capital, so he uses it to improve his cultivation.

This usage is a kind of "false way" that Yin Lan heard of in his previous life, which is to use the destructive source stone to swallow a huge amount of spiritual energy to form a black hole, and then, use unique secret techniques to incorporate the violent spiritual energy that forms a black hole into the Qi sea for practice!
