Fang Yi drew the lines of the Spirit Gathering Formation on the paper.

The brain starts to make conclusions and conjectures.

"What if I use a storage card to seal the spiritual energy pattern in it?"

Just do what Fang Yi says.

It was immediately engraved on the card virtual machine.

The storage card was first engraved, and then Fang Yi carefully engraved the aura overlay pattern on the gap between the physical lines of the storage card.

It's just a simple aura overlapping pattern, because the space on the empty card is not enough.

Fang Yi frowned slightly.

Buzz!

He pushed the storage card.

A bright light rose from the card virtual machine, and spiritual energy patterns appeared in mid-air.

Dissipated quickly immediately.

"no……"

Fang Yi shook his head.

This will still make mistakes.

"Not only will the spiritual energy overlapping patterns dissipate quickly, but even the originally engraved storage patterns will also disperse."

He glanced at the chaotic physical lines on the card virtual machine and shook his head helplessly.

The small space created by physical lines can only store physical things. It cannot accommodate lines composed of spiritual energy. The lines just now were engraved on the empty card by Fang Yi ingeniously.

It existed in the empty card, and the aura overlapping pattern was stimulated, which not only dissipated directly, but also destroyed the original pattern on the storage card.

Failed again.

Fang Yi shook his head slightly.

Various tests began immediately.

He tried to carve the pattern on a board and put it into a storage card. This time, he used a physical medium to bring the pattern into the storage space. However, the pattern could not be stored for a long time. After about half an hour, the aura gradually disappeared.

Dissipated.

He tried a series of conjectures in succession.

Just like that, the afternoon passed.

He ate a bowl of instant noodles as quickly as possible and then continued his research.

"Failed again..."

"Am I thinking about everything?"

Fang Yi took a deep breath.

A gust of cold wind blew by, and he hurriedly walked over and closed the window. The night was as dark as ink, and a few stars dotted the night sky.

It's late at night.

Fang Yi glanced at the time.

2:24

It's two o'clock in the morning...

Fang Yi sighed.

"I didn't pay much attention to the time. I didn't expect it to be so late. It seems that I need to manage my time well in the future. Otherwise, if this continues, I may become more energetic later and develop dark circles under my eyes."

"I've been studying it all afternoon, but there's still no breakthrough."

"I still feel like I'm thinking a little too complicatedly..."

Hold a cup of wolfberry water in your hand, which is slightly warm.

Don't ask where the wolfberry comes from.

The scientific researchers had no choice but to hide wolfberry under the bed in the dormitory.

There was a bit of coolness when he stood by the window, which made him shiver.

He glanced at the water glass and shook it twice.

His eyes straightened.

Inspiration suddenly came to my mind.

He threw it hard.

Click!

The thermos cup broke instantly and the wolfberries spilled all over the floor.

"Yes, yes, if the thermos cup is a card, the wolfberry is the spirit gathering array."

"Why should I dwell on the matryoshka problem?"

"Cards are the medium that holds the spirit gathering array. When needed, crush the empty cards directly to release the lines inside..."

Fang Yi did as he was told, immediately walked to the table and picked up the spirit engraving pen.

"Um?"

"No more spirit stones?"

Why did he suddenly feel so embarrassed? In one afternoon, he used up all the three spiritual stones that came with him...

Two o'clock in the morning...

Clang.

He pushed open the door.

Gu Dongqing:???

"Lao Gu, here are four spiritual stones!"

Gu Dongqing was almost frightened to tears.

How the hell did you know I just came back!

"Sneaky, hurry up, I know you have a spiritual stone."

"you……"

"Fifty thousand pieces, two hundred thousand will be transferred to you."

Seeing that Gu Dongqing was still in a confused and frightened state, Fang Yi went over and grabbed a handful of Gu Dongqing's weird big windbreaker.

Wow!

The sound of the collision of spiritual stones came from inside.

"Keep it secret, you must keep it secret."

Gu Dongqing had a sneer on his face.

After getting the spirit stone, Fang Yi couldn't help but laugh.

What on earth is this kid doing every day?

Came back so late at night.

The body is covered with spiritual stones...

But this is someone else's secret, and Fang Yi doesn't have much interest in it.

He took the spirit stone and returned to his room.

"Finish this last guess before three o'clock and be a time manager."

Fang Yi began to carve.

An empty card.

He didn't even engrave the ten basic lines, but directly engrave the spiritual energy overlapping patterns inside.

"Release without using cards."

"Crush the empty card directly..."

Click!

The empty card in his hand shattered, and immediately the lines inside appeared directly, and Fang Yi slapped it with his hand.

With the lines in the air, he pressed directly to the ground!

Done!

Fang Yi immediately withdrew the formation pattern, but he knew it was successful!
