Inside the cave, below the altar, Adès stood as if waiting for something, and he remembered what Ward had just said, the city tree's control.

The vast majority of magicians are technical nerds, and they don't like to manage the affairs of the magic tower or the magic city, and when the magic tower spirit is not perfect, and can only do things according to the orders of the magician, the city tree, a super magic plant with the advantage of intelligence and intelligence, has become the best choice to manage the magic tower or the magic city instead of the house mage.

Therefore, the tree species that spread from the Zall population have naturally become the research object of magicians, and under the collective efforts of the vast group of magicians, the control method of the city tree has been cracked, which is also an inevitability, and it is impossible to say that others cannot master it, and Zall is not a higher race, and even the city tree is just the descendants of the tree of life, and the method of controlling the city tree cannot be hidden.

The method is very simple, that is, when the city tree is still a seed, sign a contract with it according to the control method of the magic pet, and then you can treat the city tree like the magic pet, but there is a major problem here, that is, the lifespan of plants is generally very long, not to mention the lifespan of super magic plants like the city tree, and the lifespan is calculated in thousands of years.

In the long years, as the City Tree grows, its strength will increase, especially in terms of spiritual power, it is easy to have a situation where the servants ∞are ♀ strong and the master is weak, and if you don't pay attention to the terms of the contract, you will be used by the City Tree, or even backfired, if it is a human being. With a short lifespan of only a few decades, it's good that he is the original owner of the City Tree. When the contract is first signed, it is well restricted, and this kind of thing will not happen.

But if the original owner is old. Do you want to pass on the city or the magic tower to future generations?

Even if you can use the means of inheriting the demon pet to transfer the contract to the next generation's control, if there is a slight accident here, it will be easy to encounter the counterattack of the city tree, especially when the strength of the inheritance contract owner cannot suppress the plant, it is more likely to have such a problem.

This is also the most troublesome thing for Terran magicians like Ward, if they can't improve their strength to a state that can compete with the City Tree before the original owner inherits the contract to the next generation, then it will be very troublesome to re-sign the contract, after all, this super magic plant is also a kind of intelligent creature. It has its own ideas.

Of course, for immortals like Adès or Willina, there is no problem at all, or some elven magicians, some magicians who can transform themselves into lichs, without the short-lived limit, there are no zài problems, but this can only be said to solve part of the trouble, and the trouble of inheritance of future generations has not been solved, even if it is solved in one generation. What about the next generation? There will be endless generations, which means endless troubles.

In the long history of magic, there have been problems of one kind or another, and most of them have been in the process of inheritance. The suppression of the City Tree could not be maintained, and the resulting city was destroyed and its citizens slaughtered. There are all kinds of strange incidents.

Later, after the magicians perfected the magic tatar. In the construction of the magic city, I abandoned the troublemaker of the City Tree, and I was bored with it. No matter how good Taling is, there is no problem in this regard at all, as long as the magician gives the supreme authority of the magic tower general control room to others, Taling will also be transferred, and it is not as troublesome as the city tree.

But why would Ward say this, instead of mentioning the construction of a magic tower between Ades, according to the general situation, Ades is now also satisfied with the financial resources to build a magic tower, why should he talk to Ades about the source of this trouble.

This involves the ability of the magic tower, yes, the magic tower can also suppress the volcano, and it can also extract the energy in the magma as the energy to drive the magic tower, but this does not mean that the magic tower can control the magma, in case the magic tower fails, or the speed of extracting energy is not as fast as the magma lake can produce magma, the volcano will still erupt.

The City Tree is a super magic plant, as long as the energy can keep up, it can infinitely extract energy to grow itself, and even when there is a surplus of energy, it can make some energy gems out and supply them to the owner of the City Tree.

Of course, the magic tower also has such a function, but the magic tower has a power problem, it can't extract energy unlimitedly, and the energy channel of the magic tower depends on the size and material when the magic array is erected, which is why the magic array built by the demon is pumping energy and gathering energy, because of the high temperature, it ablates the earth's crust and opens up the upper and lower magma chambers.

To put it simply, whether it is a magic tower or an elemental pool, it is a centralized extraction of energy, and in the process of extracting energy, a large amount of heat energy will inevitably accumulate, and the high temperature and high heat will also create new magma.

On some small volcanoes, such an energy cycle can make the magic array obtain endless energy, but on large or super-large volcanoes, this kind of cycle will kill people, and the energy of the magma lake itself will not be exhausted, and new magma will be created, the magma lake will become bigger and bigger, and finally it will get out of control, and the volcano will erupt again.

The City Tree is different, it is decentralized, it can cover the magma lake with fibrous roots, and gradually eat away at the magma lake, and the magma that has been extracted energy will turn into hard rock, blocking the possibility of volcanic eruptions.

The reason why Ward said the City Tree very contradictory is that he knows that Ades is a dragonborn, his lifespan is very long, and there will be no inheritance problems in a short period of time, and in Adex's long life, it is not difficult to choose a descendant who can suppress the City Tree in terms of strength, and such a risk is controllable.

The most important thing is that this is an island, and the area is not large, even if something goes wrong, can this big tree still cross the ocean? From Ades's point of view, the benefits of planting a city tree are far greater than the risks caused by it getting out of control, and this is why Ward will explain to Ades from the position of a friend, and ask him to carefully consider the pros and cons of the two methods.

In fact, there is nothing to consider for Adès, the City Tree is a degraded version of the Tree of Life, just like some fruit trees and animals, the ancestors are excellent varieties, and the offspring will be degraded, which is very common in nature, but the descendants of the Tree of Life also have its excellent bloodline, although the fruit and sap of the City Tree are not as magical as the Tree of Life, but after all, it is still a super magic plant, and it can also extract the life energy that Mia and Yunni need in it.

This effect alone is not comparable to the magic tower, and after learning about the various effects of the City Tree, Ades didn't think about erecting a magic tower, and directly asked Ward where he could get seeds.

It's a pity that Ward is just a low-level magician, even his teacher Nancy, there is no news about this, but Ward said that he can help ask the upper echelons of the academy to see if there is a way, and he also prompted Adès and asked Verina, she is an elven clan, and at the same time she is an elder of the forest lady, and it is easier for her circle to get information about this.

Just as Adex was pondering, Ward and Winnie walked in, alarming Ades, who saw Ward walk in and asked urgently, "Are you sure the metal blocks in the storage room are alloys of Adamantite and Mithril?"

Ward nodded very sternly and said: "It should be said that there are many kinds of metal alloys, basically the metals we commonly use are included in it, I guess it is the demon directly extracted from the magma, but this alloy is difficult to deal with, and it is basically impossible to refine each metal separately." ”

Adès opened his mouth, there was a rock chamber in the cave, it was full of metal ingots, he had known this for a long time, he had come to check with Hunter on the night he had just destroyed the demon, he thought it was just an ordinary iron ingot, and he didn't pay much attention to it.

But now Ward suddenly told him that this metal block contained gold, silver, copper, iron, tin, as well as a small amount of pure gold and mythril, as well as copper smelting produced by the long-term erosion of the fire element, not counting those magic metals, gold and silver alone were enough for Adès to surprise.

The three of them went to the secret room where the metal ingots were stored, and Ward led Adès to a slightly wider place, pointed to the wall in front of him that was stacked with metal ingots, and said, "Look at this metal ingot, I scraped it open here with a sharp weapon, and its color is obviously wrong, it is not an ordinary iron ingot. ”

After saying that, he used a light spell, and Winnie also performed a light spell next to him, two balls of light suspended in mid-air illuminated the entire secret room, and Ades saw a stack of metal ingots in front of him, and at the height of his chest, a metal ingot had been scraped, which should be the one Ward said.

He took a closer look, and as Ward said, this metal ingot was pale gold, and it should be said that all the metal ingots here were about the same color, and when he came to see it before, he didn't pay attention to it, and there was not enough light to observe, so he didn't notice that the color of the metal ingot was different from that of ordinary iron ingots.

The most important thing is that the entire secret room here is full of metal ingots, too many, dense, stacks of stacks, each pile of metal ingots is stacked as high as two people, the passage left can only be entered and exited by one person, so many metal ingots, Ward doesn't say, how could Ades think that it was all alloy?

Ades looked at the metal ingots in the secret room, his expression was a little dull, this secret room is not small, the width and depth are at least more than fifty feet, all of them are piled up with metal ingots, how many are there?

Ades' mind was a little confused at this moment...... (To be continued......)
