Chapter 720

"Three sets of materials, that's just right, I can experiment a few more times!"

With the Eye of Omniscience in hand.

Plus expert-level Magic Card theory and card construction skills.

Su Yu wouldn't fail in constructing a Quasi-Legendary Ritual Card.

But the extra materials.

Can be used for the construction of other Magic Cards!

After his Magic Card theoretical knowledge was raised to the expert level.

Based on the settings of those fantasy world works in Su Yu's mind.

With the assistance of the 【Eye of Omniscience】.

Su Yu had come up with quite a few auxiliary Magic Cards that could be constructed!

"However, for now, let's prioritize the Mask Mode!"

After all.

This Ritual Card.

Concerns the further strengthening of the Zanpakuto: Ryujin Jakka and the third life-bound Magic Card, Gallantmon!

If he can master the Mask Mode.

Gallantmon's combat power will surely leap again!

By then.

Even without stepping into the Star Spirit level, Su Yu could easily suppress and kill the restless aliens in the star field outside Blue Star!

"Swish!"

Without the slightest hesitation.

As Su Yu.

Moved his mind!

The Source Energy materials flew up directly!

Su Yu now.

With the mastery of the "Wa Emperor Guidance Method".

The Source Energy in his body had all been converted into higher-level cosmic spiritual energy!

Under the drive of spiritual energy.

Even Half-Saint Tier materials.

Were quickly processed!

Turning into clusters of incomparably pure liquid energy, hovering in mid-air!

At the same time!

In front of Su Yu.

The Magic Card slate hovered in the air.

A stylus pen condensed from spiritual energy.

Moved in mid-air under the traction of spiritual energy!

Magic array circuits were also quickly taking shape!

Just as Su Yu.

Began the construction of the Ritual Card: Mask Mode!

Outside the Hanging City!

Shen Tianyu and Nantian Yue.

Were already preparing to bid farewell and leave!

However.

Just at this moment!

"Hum—"

Inside the Hanging City.

In the direction of the card construction room.

An incomparably miraculous spiritual energy fluctuation was suddenly released!

"Bang—"

The moment this fluctuation shook out.

The entire Hanging City shook faintly!

"What's going on?"

"Is the Magic Card Saint Su is constructing already finished with the first step, and starting to draw Source Energy?"

The three Shen Tianyu.

All changed color!

Looking in the direction of the card construction room.

Their voices.

Were faintly trembling!

As Half-Saints.
