Inside the black door, Richard walked in.

Looking at it, you can see that inside the door is a huge palace, with a radius of nearly 100 meters, an area of nearly 10,000 square meters, larger than a complete football field, and the height is more than ten meters, majestic and magnificent, as if you are just a speck of dust in it.

At this time, in this huge palace, there are golden stone tables densely arranged neatly, and the surface of the stone tables is carved with complex magic patterns and brightly colored patterns. As far as the eye can see, the number of stone tables is in the thousands.

On each table, there was a thick scroll.

Is that......

Looking at the scroll on the stone table, Richard raised his eyebrows, and without hesitation, strode over. I walked up to a table and spread out the scroll on it, and I saw that there was dense text written inside, starting with the title: A detailed explanation of energy storage.

Approaching another table and opening a new scroll, the subject has changed: On the Advantages and Disadvantages of Multiple Ways of Energy Storage.

Walk near the third table, open another scroll, and the subject changes again: On the relationship between energy storage and the material of the container.

"It seems to be all about energy storage, which is the technology involved in the Black Energy Storage Short Staff. Richard muttered to himself, noticing a black conch on a nearby table.

After thinking about it, he walked a few dozen meters to the right, came to the front of the table in another place, saw the pattern on the table turn into a red flame, and reached out to open the scroll on it.

The scrolls are still densely packed with text, which is a headache to read, but the title is extremely clear: many ways to increase the power of fire-based spells.

The table on the left, also with a flame pattern, opens the scroll on it, titled: A detailed explanation of the principles of lava-based fire-based spells.

On the table on the right, still with a flame pattern, open the scroll on it, title: Comparison of Fire Spells with Other Plastic Energy Spells.

Looking up, looking at the many tables around him, looking at the various colors and patterns on the tables, Richard had some enlightenment, and said to himself: "It seems that all the tables are similar scrolls, all of which record knowledge, divided into different categories. So, the ultimate treasure of the Black Spirit King is no longer a gold and silver treasure, but a lot of magic knowledge left behind......? An empire's top-secret library?"

"That's pretty good. Richard muttered, his eyes lit up, and this knowledge seemed to him to be much more precious than any gold or silver treasure.

Really mastering all the knowledge here can not only greatly improve his strength, but also allow him to further peek into the framework and core of the current world's spell system, which can help him deeply understand the truth of the current world.

And what he has been doing, not hesitating to leave the Blue Lion Kingdom, suppressing all kinds of emotions, and giving up pleasure, is it just to find out the truth of the world and figure out why he came to this world.

Only by seeing the way he came can he determine which direction the future road will take, and how to go right.

Take a deep breath and feel the air pass through the filters of the mask into your nose, down your trachea into your lungs, through the capillary network of alveoli into your bloodstream and throughout your body.

Richard's eyes widened, and he strode to the side, picked up another scroll, and began to browse carefully.

The title of this scroll is long: on the principles of wind spells, their commonality with water fluids, and the use of wind spells in speed amplification and wide area perception......

......

Meanwhile.

On the ground, it was afternoon, and the sun was streaked due south, slightly deflecting towards the west.

The warm winter sunshine is the most sleepy and slack.

Just when many people were sleepy and slack, two figures appeared on a hill in the field, one was Sig Adolf, the director of the Deep Blue Castle, and the other was Bayer, the emissary of the mysterious organization.

The two squinted their eyes at the line of defense where the sun had deflected, where a large city was standing. The gates of the city are wide open, people come and go, and it is very lively. At the same time, there were also figures flying from the sky, either entering the city or coming out of the city, all of them were obviously powerful wizards.

After watching for a long time, Baier turned his head to look at Sieg and asked aloud, "Dean Sig, are your people ready?"

"Huh. Sig said with a straight face, "Of course my people are ready, and they are almost impatient! I want to ask you, are your people ready? ”

"Don't worry, absolutely not, as I said before, all the manpower has been mobilized, just waiting for the attack order. "Byerdo.

"That's for the best. Sig's expression softened slightly, "In that case, don't be verbose, let's attack." ”

As Sigurg's words fell, a large area of air behind him distorted and deformed, and dense wizards appeared, each wearing dark blue flying fish wizard robes, with a solemn face.

"Okay, just follow what Dean Sieg said, attack. Bair also said.

A large expanse of air behind him distorted, revealing a large group of wizards in dark black robes.

The next moment, without commanding, the bodies of the many wizards who appeared swept out, clinging to the ground and quickly approaching the big city in the distance.

......

About the same time.

In the city, in a house.

Wizard Eva frowned and looked at the wizard under him, and asked aloud, "How is it, there is still no news from Richard?"

"This ......," the wizard hesitated for a moment, then shook his head, "still not, but I think it's going to be soon." ”

"Oh well. Eva the wizard nodded, "Then wait for him, don't be too anxious, after all, the time has not yet come." ”

"Yes. The wizard nodded.

Eva didn't say anything more, stepped out the door, and then blinked her eyes to see a powerful wizard next to her approach. There was an invisible transparent energy condensed around the other party's body, making the light appear a little distorted, like an energy black hole, which was none other than the elemental master Russell.

"Hello, Master Russell. Eva greeted.

"Hello Eva Wizard. Russell looked at the response and said casually: "Andrew, the 'Voodoo Heart' of the Rotten Swamp, the 'Water Spirit' Gal of White Mist City, and Tris, the 'Source of Grudge' of Heieburg, have all brought people here, ready to participate in the decisive battle discussion. By the way, what's the situation on your side, there's nothing wrong with it, right?"

"Nope. Eva shook her head and replied, "The people on my side are basically all together, and occasionally there are a few who have not sent back news, and it will be about the same by night, and tomorrow's decisive discussion can be carried out normally." ”

"That's good, then I'm relieved, it seems that this time I can successfully concentrate my forces in one place and let Deep Blue Castle understand......" Russell said loudly, but halfway through his words, he suddenly stopped and turned his head to look in the direction of the outside of the city.

Well?

Eva was a little puzzled, and looked at it together, and after a while, she sensed something, her face changed suddenly, and she opened her mouth to send a warning.

Russell was faster than her, shouting "enemy attack", and the sound quickly spread throughout the city under the effect of the spell. Then Russell's body soared into the sky, like a meteor, flying towards the outside of the city at high speed.

Then there was a sudden light outside the city, as if the sun in the sky had fallen and exploded. With an astonishing light and heat, sound waves and vibrations were transmitted rapidly in all directions, and an entire wall of the city was shattered in an instant.

In an instant, everyone understood, and the decisive battle, which had not been discussed, began in advance.
