On the Lost Ground side, Fen took the seeds of the World Tree, his apprentice, the necromancer Marquis Baran, and the long-serving guard, Stone, to the Twin Towers of the Gate, in front of the Magic Tower on the Lost Ground side.

On the abyss side, Lin took Halumi and Kaya directly to the third floor of the magic tower on the abyss side, before booking the location of the energy pool.

On the side of the fascination, Fen changed into a four-spirit robe, inserted a phoenix hairpin, and held a short wand made of the branches of the World Tree in his hand. This is her strongest aggressive form. The reason why she doesn't use box-cutting weapons is because she doesn't like to be spied on in her inner world, and she doesn't believe in box-cutting discipline.

Behind her, the Marquis of Balan was dressed in a black robe made of magical silk. Not only did the robe have a hood and veil that covered his face, but the long sleeves and hem also covered his limbs so that not an inch of skin was exposed.

Stone put on a simple cuirass, bracer guards, and leggings, and focused on a whole row of lightsaber hilts on his waist. The blade of the lightsaber is materialized from an extremely high concentration of eight powers, and it is only extended during battle, which is suitable for different situations.

And he was holding a wooden box in his hand. The box contains the precious seeds of the World Tree, which are used to create the magic tower's energy pool. In fact, the wooden box is also famous, but here it is just to prevent the breath of the World Tree Seed from leaking out and avoid attracting attention.

On the abyss side, Lin was wearing his most powerful sky-blue robe, holding a colorful pearl feather fan. It's just that this attitude has no effect in front of his two apprentices. Anyway, I've seen the appearance of my bare buttocks, and I want to pretend where to go.

Harumi was dressed in a light ivory robe, and it didn't look like any fancy decorations. But if you look closely, you can see that there are silk threads of similar colors on the robes, and uncommon magic secret texts are woven.

When illuminated by a light source at a specific angle, the robe is able to reflect a silky sheen of different colors. This will make the soul of the person who sees it feel as if it has been washed, and it will make people feel relaxed and calm.

The clothes on Kaya's body were not so much a robe as a purple dress that made her look as noble and elegant. Although the style is simple, the tailoring is not a revealing route.

A one-sided left shawl, with this dress, combined with her own quiet atmosphere, makes her temperament different from that of secular nobles, like an otherworldly goddess.

She is over thirty years old, and she no longer has two childish braids like in the past. But the curtain-like bangs in front of her forehead, and her long straight hair tied into a ponytail, the new look made her teacher still not know what to say after seeing it.

I can only sigh that this girl's aesthetics are as unique and different from ordinary people as they were when she was a child. I used to be an elementary school student, but now I have only evolved to the level of a junior high school student.

But of course, this is not the time to criticize his two little apprentices. Lin sent the two of them to inspect the various facilities on the third floor of the magic tower on the abyss side. Do the final checks before the energy pool goes online.

At the same time, on the side of the maze, Fen took his apprentices and guards and took a little time to admire the busy construction site of the machines, an unprecedented magic array city.

Due to the limited supply of materials, the enchantment of houses has not yet been fully completed, and most houses still only maintain the appearance of earth embryos.

The project is basically centered on the magic tower and radiating outward. But it is not a building by a unit, but a special combination of units to complete.

And this combination is a complete functional loop. Although it may be only a small part of the large magic circle, as long as the circuit is formed, the magic circle can start to work.

With the new magic stone-shaped energy pool for energy, it represents the magic array arranged in this part of the city, which was activated earlier than the magic tower. However, because the magic circle is still not fully unfolded, only a small part of it, the effect it should have has not yet been exerted.

This means that the house near the magic tower has been enchanted, and the part of the construction is a distant earthen house. Therefore, the scope of the machine's operation is far away from the location of Fen and others.

In fact, the moment Fen used the flashing technique to appear, it also aroused the vigilance of the machines.

However, as one of the two humans who participated in the unification battle of the earth elemental plane throughout the whole process, Fen's appearance is also familiar to the mechists. Therefore, after confirming the identity of the visitor, the machine people no longer care about the affairs of the magic tower.

Anyway, the magician sent it before, and the request for temporary changes took them a lot of effort.

In someone's mind, micron-level operations are something that can be done by robots. But not all machines can do it, otherwise all machines will be able to self-transform and self-repair.

There are only a handful of people in the group who can make those design changes that have been modified.

Their daily routine is to help the machine to carry out the transformation of the core category, and the business is so heavy that ordinary people can hardly imagine. Even when he came to the maze to prepare for the battle, the related work did not stop.

So when someone temporarily asks for a change, the robot can be said to be a chicken, a dog, and a dog. The bigwigs who can do this kind of micron-level operation are dissatisfied and shouting to strike. Only in the end, they got the job done before someone arrived.

For no reason, it's different from Party A, who travels through the hometown and is responsible for paying. This is not a rich uncle, if any Party A has the ability to beat Party B, he will not be responsible afterwards, probably no Party B dares not to work hard.

How the saying goes: It's better to sweat than to bleed.

The robot fleet washed the demons in blood, the Abyss Lord washed the machine man in blood, and a certain magician washed the Abyss Lord in blood. It would be a joke to think that the demon could turn around and beat up a magician. So it was a reasonable thing to do to follow the magician's request.

Therefore, the hard work of the machines is not because they are willing to abide by their promises, nor because they are all intent on currying favor with a certain magician, but simply succumb to great power.

Finn doesn't care what the people really think. Or rather, there wasn't much she cared about in this world, including the one she was going to do now.

When life is just living, and everything is done just to pass the time, that person's mood will be the same as Fen now, and it doesn't matter what he sees.

So after glancing at the big construction site of the machine people, she didn't have any extra emotion, so she led the two people behind her and walked to the inside of the magic tower.

On the abyss side, Lin had to prepare much more than Fen.

Although the two magic towers on the abyss side and the maze side are exactly the same in structure and design, the most critical energy pool is completely different from the strange things that make up the core.

As mentioned earlier, it is quite easy to use the seeds of the World Tree to build an energy pool. He's a magician, and he can do it according to the table. Therefore, Lin was very relieved to hand it over to Fen, even if there was any emergency, with the knowledge reserve of the former Demon King, he could handle it very properly.

However, the magic tower on the abyssal side will use the stump of the unspeakable to build an energy pool.

If you use various strange objects as the core of the energy pool, there is a hierarchy in the difficulty of building. Then the energy pool of the World Tree Seed is undoubtedly the least difficult. The difficulty is highest when using any part of the unspeakable to build energy.

The sheer difficulty of the problem is certainly not the reason for thwarting Lin's actions. Who has ever seen an otaku retreat because the game is too difficult, even if it is a souls-based game, you have to play until you break through the sky. Of course, it takes some time to study and practice.

In the same way, it is only difficult to build an energy pool with the strange things in your hand, not impossible. So in order to complete this difficult work, it is necessary to make good preparations in advance, and plan all possible accidents in case of emergency.

To this end, Lin needs a helper to help himself and make success more secure.

The two older girls are no strangers to the Magic Tower. Of course, Halumi and Kaya are quite familiar with mathematics, and even the various mechanical structures and technological products that someone likes to use.

Maybe they didn't reach the height of the machine or the box cut, but they knew better than the craftsmen of the Technology Guild. In addition to the fact that they are closer to their teachers and have more resources; Craftsmen focus more on the knowledge required for their craft, and rarely broaden the breadth of their knowledge.

It's like someone's hometown, in most cases, theoretical scientists have a higher level of academic knowledge than applied scientists. Most of the latter's efforts are focused on how to put the knowledge into practice and then find a more suitable process, the so-called 'commercialization'.

However, the former has to do the latter's work, and it is not completely impossible, but it needs to be properly guided, and there is a difference in efficiency. It's just that the situation of the two older girls is still a little different.

If it is said that in the Lost Land, Lin Hefen is already an intellectual at the professor level, the ordinary people in the Lost Land are illiterate, and the craftsmen of the Technical Guild are at the elementary or junior high school level, then the two older girls are at the level of college students.

To put it simply, to act according to their own ideas well, maybe the hands-on ability of the two apprentices is not as good as those craftsmen, but they are definitely much better than those craftsmen in terms of understanding and cooperation.

Therefore, your own apprentice is the best helper. There is no better person to trust.

In order for Halumi and Kaya to help in the rest of the matter, Lin took the time to explain what he was about to do, what the two apprentices should be aware of, and what they could and should not do.

At least, Lin didn't want to deal with the energy pool of the magic tower on the abyss side at the cost of two crazy apprentices. Therefore, pre-departure education is very important, and it is more important to let the two girls know that it is more important to protect themselves.

As for the idea of simply excluding them in order to protect them, Lin didn't even think about it. One cannot choke on food, nor can one deprive others of the right to make mistakes in the name of love.

As long as the mistake is not fatal, or can jump sideways on the edge of the mistake repeatedly, it is better to accumulate such experience than to face similar challenges without experience.

Sooner or later, danger will happen to the person you love. Instead of protecting them everywhere and then regretting their negligence, it is better to teach them to protect themselves early on.

So someone spares no effort to pit his own apprentices, and then conclusively says that this is exercise!
