Chapter 658 You Came at the Right Time

After Nico erased the space expansion array that Lin En had refined, the expanded square training ground also returned to its original appearance.

After learning from Nico about the shortcomings of the space expansion array he had just refined, Lin En waved his magic wand again and refined the space expansion array again.

And this time the space expansion array was much more perfect than the previous one, and the shortcomings Nico raised were also improved in this space expansion array.

However, Nico seemed to be still dissatisfied with this space expansion array. He waved his magic wand again, erased this space expansion array, and put forward new opinions.

Even if Nico's opinions were all some almost undetectable flaws in this space expansion array, even if no modifications were made, it would not affect the operation of this alchemy array.

But Lin En still obeyed Nico's request, and started over again and again, refining space expansion arrays one after another.

After Lin En refined the 43rd space expansion array, Nico finally nodded with satisfaction, looked at the perfect space expansion array under him, and said: "Very good, these expanded training grounds belong to you."

"In the next five days, I hope you can practice the space transmission array and space blockade array to this level. In these five days, you can ask me any questions at any time, and after five days, I will test your practice results."

Nico said so.

Hearing Nico's words, Lin En couldn't help but smile bitterly.

Although the space expansion array, space transmission array and space blockade array are all alchemy arrays, the difficulty of refining these three alchemy arrays is very different.

If the space expansion array is equivalent to the floating spell, then the space transmission array is equivalent to the Avada Kedavra curse, and the space blockade array is equivalent to the difficulty of learning the Patronus spell after the soul is polluted by black magic!

With Nico's strict requirements for alchemy arrays, Lin En refined even the simplest space expansion array forty-three times before he refined an absolutely perfect space expansion array without any flaws.

Then, how long would he have to practice the more difficult space teleportation array and space blockade array? !

Thinking of this, Lin En no longer wasted time on meaningless thinking, but walked into the training ground he had expanded, waved his magic wand, and refined the space teleportation array.

The characteristic of the space teleportation array is point-to-point transmission, and because its transmission principle is point-to-point transmission based on coordinates, rather than linear space shuttle.

Therefore, no matter how far the distance between the starting point and the end point of the space teleportation array is, the magic power required for space teleportation is the same.

So, Lin En directly set the starting point and the end point of the space teleportation array in this square training ground, with a distance of only a few meters between the two.

For a day and a half, Lin En spent a whole day in this square training ground, refining the space teleportation array over and over again, and when he was confused, he would ask Nico without hesitation.

In the evening of the second day, under Nico's witness, Lin En finally refined a perfect and flawless space teleportation array.

Lin En slowly walked to one end of the space teleportation array and injected magic power into the golden and silver intertwined lines under his feet. With the white light on, Lin En's figure appeared at the other end of the space teleportation array in an instant.

Looking at this scene, Nico nodded slightly and said: "Below the Demon King level, your space teleportation array has reached the extreme. Only the existence of a wizard who has been promoted to the Demon King level with alchemy attainments can intercept its transmission with the space blockade array he has refined."

After getting Nico's evaluation, Lin En finally breathed a sigh of relief, and a bit of joy appeared on his face.

In the entire magic world, the only existence who has advanced to the level of Demon King with alchemy attainments is the defeated goblin Arnold, except for Nico Flamel, who is his master in front of him.

As Nico is his master, he will naturally not become his enemy, nor will he break his space teleportation formation.

And the goblin Arnold is rejected by the alchemists among wizards. It is impossible for him to learn the space blockade formation from wizards, let alone refine the space blockade formation to intercept Lin En's space teleportation formation.

This also means that the space teleportation formation refined by Lin En is now unsolvable!

In the remaining three days, Lin En devoted himself to the practice of the space blockade formation.

The difficulty of the space blockade formation is much higher than the previous two combined. Lin En spent three days, but still failed to refine a perfect space blockade formation without any flaws.

Fortunately, the power of the space blockade formation is very overbearing. Even if the space blockade formation refined by Lin En is not perfect, it is still no problem to intercept the space transmission of the floo network and the door key, as well as the phantom movement performed by the demon king-level wizard.

Only the space transmission formation refined by the alchemist who has advanced to the demon king level with alchemy attainments can break through his space blockade formation.

Because of this, Nico was not so strict with Lynn in the space blockade formation. After checking Lynn's practice results in the past three days and confirming that Lynn had made extraordinary progress in the past three days, he let Lynn pass.

After Nico checked Lynn's practice results, Lynn said goodbye to Nico and Green, and took the cross-border arbitrary door key to Newt's villa.

"Lynn, you're here! Come in!"

Irina, who got the news in advance from the two-way mirror, stood at the door of the villa and said happily.

Lynn came over, kissed Irina's forehead lightly, then looked at Newt in the living room and saluted slightly: "Professor Scamander!"

Just like Fred and George, before they became Green's teachers, they all used Green's name when he was still the professor of Defense Against the Dark Arts in Hogwarts Castle.

Lynn also used Newt's name when he was the professor of Care of Magical Creatures in Hogwarts Castle.

Newt smiled and waved his hand, saying, "Don't call me 'Professor' anymore. I've resigned from Hogwarts, haven't I? Come in, you're here just in time!"

As he spoke, Newt took out the sixteen pure white cubes that were placed in the living room and protected by protective magic.

Lin En raised his hand and stroked a pure white cube. He could sense the magic fluctuations of his own alchemy array in this pure white cube, which came from the universal energy stabilizer he refined. (End of this chapter)
