Chapter 400 The ultimate traceless stretching spell, the teaching of any door key!

In more than a week, Irina has gained Newt's complete understanding of the Traceless Stretch Spell, which allows Irina to rapidly increase the conversion rate of the magic power in her body into space power when she casts the Traceless Stretch Spell.

After Newt taught Irina the last lesson about the Traceless Expansion Spell, Irina's original space expansion rate of 125 billion has been increased to 800 billion!

Today, she is not far from the trillions of space expansion magnification required by Newt. Moreover, every time she casts the Traceless Stretch Spell, her space expansion magnification will be significantly improved compared to the last time.

Looking at Irina whose space expansion magnification was steadily increasing, Newt was convinced that after Irina thoroughly digested the knowledge he taught, the space expansion magnification of Irina's Traceless Stretch Spell would definitely reach one trillion.

Irina also lived up to Newt's expectations.

On the night of July 14th, under Newt's watchful eye, Irina once again cast the Traceless Stretching Charm on the wooden box.

As the space inside the wooden box continues to expand and extend, the magic power in Irina's body is also rapidly consumed.

But compared with two weeks ago, every time Irina consumes a point of magic power, the power converted into expanding the space inside the wooden box will be several times greater!

After the magic power in Irina's body was almost exhausted and she stopped casting spells, Newt waved his wand again to summon the light gate.

However, the two did not walk into the light door like the first time. Instead, they stood outside the light door and stuck their heads out to look inside.

"Yes, the space expansion rate here has reached one trillion. If the carrier you use to release the traceless expansion spell is a suitcase, you can create a space equal to the size of my small world in the box!"

Newt's head passed through the light door, and after looking into the space inside the wooden box, he quickly retracted his head and said to Irina with satisfaction.

Compared with the space expansion rate of 125 billion two weeks ago, today's space expansion rate of trillions appears in the space inside the wooden box, which will only become more unstable and easier to fragment.

Therefore, Newt would never dare to put himself in danger and enter this space that could completely collapse at any time.

Otherwise, with the fragmentation speed of the unstable space with trillions of space expansion magnifications, he would probably be completely torn apart by the fragmented space before he could escape from the light gate.

Looking through the light door at the constantly fragmenting space on the other side, Irina seemed to have some realization.

If the broken space can tear the human body apart, then if the space where the enemy is located is broken, wouldn't it be possible to directly tear the enemy into pieces through the air? !

After Irina successfully cast the Traceless Spell with trillions of spatial expansion magnifications, Newt stopped her training on the Traceless Stretch Spell.

Nowadays, Irina has reached the ultimate level of understanding and mastery of the Traceless Stretch Spell. Before she is promoted to the Demon King level wizard, it may be difficult for her to improve on the Traceless Stretch Spell.

Going too far is not enough. Instead of letting Irina waste her energy on the Invisible Stretching Spell, it would be better to teach her more of what she has learned throughout her life.

"I'll give you a day to rest and take care of the magical animals in your suitcase. On July 16th, we will continue to learn how to make portkeys."

Newt said to Irina.

Irina was naturally happy to hear this.

Although she is very eager to improve her own strength, everything requires a combination of work and rest.

Even Lin En, who is obsessed with alchemy experiments all day, will leave himself a certain amount of time to relax, not to mention Irina, who is more playful in the first place? !

Irina immediately got into her suitcase and fed the magical animal food that Newt had prepared for her to the little ones living in different areas.

Including the Bowtruckle Green Girl and her tribe, Sniffing Little Treasure, Little Gallon and Little Xiko, Little Winged Demon, Thunderbird Tim, Invisible Beast Silver Sparkle, Bird Snake Ruyi, six Moon-Crazy Beasts and six Ball escape bird.

After feeding these little ones, Irina played with the clingy Moon Crazy Beast, Qingnu, the little Winged Demon and Tim for a while. It was not until the night of July 15th that she was still not satisfied. Got out of the suitcase.

Irina slept soundly in the room Tina arranged for her. It wasn't until midnight the next day that Irina got up sleepily.

Newt rarely asked her to get up, but allowed her to wake up naturally. After breakfast, he started teaching the portkeys.

"Take these nine objects and make them into trigger door keys, rechargeable door keys and timed door keys respectively. The types of door keys are ordinary door keys, cross-border door keys and arbitrary door keys. Let me see you. today’s level.”

Newt said this as he handed nine emerald green teacups of the same size to Irina.

Irina nodded, she raised one of the emerald green teacups, lightly touched the wand on the teacup, and whispered: "Mentos!"

A flash of white light flashed, and the inside of the teacup was filled with weak magic power fluctuations.

"This is an ordinary trigger door key, and its destination is the corridor on the second floor of the villa."

Irina used magic to isolate the teacup from her hand and handed it back to Newt.

Newt took the portkey, and the next moment, his figure twisted and disappeared.

But in less than a second, Newt apparated back to Irina.

After that, Irina made rechargeable door keys and timed door keys among ordinary door keys, as well as trigger door keys, rechargeable door keys and timed door keys among cross-border door keys.

For door keys with the same teleportation distance, whether it is a trigger door key that triggers upon contact, a rechargeable door key that automatically triggers after injecting magic power, or a timed door key that automatically triggers when reaching a designated time node, Irina spends The time and magic power are almost the same.

It takes Irina about five seconds to make an ordinary door key, but it takes nearly five minutes to make a cross-border door key.

At this time, Irina only had three emerald green tea cups left in her hands.

"Mentos!"

Irina once again chanted the magic spell on an emerald green tea cup. This time she planned to make a trigger-type arbitrary door key.

The transmission destination of any door key is not decided by her, the maker of the door key, but by the user of the door key. This concept of door key operation is the first time it has appeared in the entire magical world.

Since making an arbitrary door key requires taking into account the possibility of a large number of destination coordinates, the time it takes for Irina to make an arbitrary door key is much longer than making a cross-border door key.

After more than half an hour, the trigger-type arbitrary door key was completed. It was lying quietly on the coffee table between Irina and Newt. (End of chapter)
