Spirit summons? I want to do it myself!

Although Lido wanted to use local materials to find a handy tool in the cave to dig a hole between the mountain wall and the mother ore, and then peel the mother ore off the mountain wall, to be honest, Lido was a bit helpless.

After three thousand years of erosion and scouring by groundwater and water magic elements, the meteorite itself, the surrounding mountain walls, and the stones on the bottom of the water have mostly become round and extremely hard. The stones on the mountain walls and the stones on the bottom of the water can be completely called magical materials.

So Liduo couldn't even find a sharp object, let alone grinding it on the spot! Even if she put the fishhook in again, it would be useless.

Last time, only a small part of the mother ore beads were connected to the mountain wall, so Liduo still had room to make a move. But this time, the meteorite fragments were completely embedded in the mountain wall, and there was no room for tricks. She had to force a hole out!

Fortunately, Lido is not helpless. This is all thanks to Lido's understanding when she learned the Ice Armor and the inspiration brought to Lido by the Dragon-Tooth Turtle.

In order to master the spell circuit of the Ice Armor, Lido spent about an hour every day for about a month to deepen her control over the resonance of the water magic element.

Before this, the elemental resonance that Lido performed the most was the wind magic elemental resonance. Both Qinggong and Qingfengzhan used the wind magic elemental resonance. As for the resonance of other magic elements, she could only master the basics and had no time to study them in depth.

But as Lido has to master more and more spell circuits in the future, the training of resonance of other magic elements must also be put on the agenda. Now the resonance of water magic elements takes the lead.

It is difficult to say whether the many kinds of movements that Lido found when researching Qingfeng Zhan that could trigger resonance effects of different wind magic elements were the prototypes of wind magic skills.

When training Qingfeng Zhan, Lido often uses a random combination of several of these moves, at least one of which must be powerful or have a special effect, forming Lido's unique magical martial arts.

As one of Lido's current trump cards alongside mental attacks, Qingfeng Zhan was an epiphany that came about when the timing, location and people were right.

If you extract the martial arts movements in Qingfeng Zhan and find its corresponding spell circuit, it is a wind magic skill!

However, when Lido was training the resonance of water magic elements, she did not encounter that kind of enlightenment state. It can only be said that it is not so easy to get the right time, place and people together.

However, even with the skill of water grinding, Lido has now mastered several resonance states with different effects. For example, through the resonance of water magic elements, the water vapor in the environment is gathered to form a water arrow.

But in fact, the attack power of the water arrow is not strong. It has a certain impact force, but it does not achieve the penetrating effect. After all, Lido's mastery of the resonance of water magic elements is only at the primary stage.

What Lido was thinking about was to compress and accelerate the water arrow as much as possible, just like the high-pressure water gun of the dragon-toothed turtle, so that it could be turned into a high-pressure water gun, and some hard and fine sand could be mixed into it to enhance the physical cutting ability of the water gun. Then, even if it cannot compare with the industrial water jet in the previous life, it can at least be comparable to the water drill, right?

However, this is a method that Lido has not yet mastered, and some practice!

Fortunately, there is nothing else in the cave except a lot of water magic elements! Although it will interfere with Lido's resonance of water magic elements, the resonance effect will also become more powerful!

Lido's current mental strength is strong enough to keep herself from being washed away even by the tide of water magic elements radiated by the meteorite mother ore.

In order to avoid causing a riot of the water magic elements in the cave, it would be more accurate to say that what Lido is going to do next is not to initiate elemental resonance, but rather an alternative application of the water magic elements in the special environment of the cave.

Because Lido must accurately control the range of resonance and must not affect other water magic elements! And the power of the water gun must also be released accurately!

Then the conventional element resonance method will not work! But Liduo thought of a good idea!

That was something that Lido read in a comic fan fiction called "Naruto" in her previous life. Lido felt that it could be used as a reference here. Although the situations were different, the principles were the same!

First, you need to create a high-pressure water ball. Lido has no chakra, so she can't create a water ball directly, but the most abundant thing in the cave is water and water magic elements, so using mental power instead of chakra is the same.

With Lido's current mental strength, there is no problem in bearing objects weighing about 100 kilograms. It should be noted here that attack force and load-bearing are two different concepts.

If Lido uses her mental whip to attack physical objects, she can destroy football-sized stones, but Lido will not do so because the cost-effectiveness is too low!

Although the load-bearing capacity of one hundred kilograms is not high, it is enough at this time!

Lido deliberately used her spiritual power to wrap a large ball of water at the bottom of the cave and brought in some fine sand from the bottom of the water.

The reason why these sand grains have survived to this day is that, apart from being extremely small, their hardness is not much different from that of rocks on mountain walls or underwater. When used in high-pressure water guns, their effect is much stronger than that of the ice particles of the dragon-toothed soft-shell turtle!

Lido used her mental power to act as the outermost surface of the water ball, and then absorbed the water magic elements in the water ball into the surface of her mental power, and began to try to induce resonance among these magic elements.

Lido doesn't need a high frequency of resonance at the beginning. She only needs all the water magic elements to participate in the resonance to form a whole. This is equivalent to regenerating an inner layer of magic elements inside the surface of mental power.

Then Liduo controlled the surface of her mental power to begin to shrink inwards. Naturally, the inner layer of the magic element would shrink along with it, and the frequency of the resonance would gradually increase as it shrank.

Then it is natural that the water ball wrapped by the inner layer of magic elements will be compressed, and will also be given quite good initial kinetic energy by the resonance of the magic elements.

When the endurance of the surface layer of mental power is about to reach its limit, it is necessary to open a hole the size of a sewing needle on the surface layer of mental power and the inner layer of magic elements to release the pressure inside the high-pressure water ball.

At this time, the tiny water column ejected from the pinhole has extremely high pressure and speed, and is mixed with hard sand to increase the cutting ability. It should be able to cut through the hard mountain wall.

This is the principle, it is not very complicated, but it is not as easy as it sounds to actually do it.

Lido failed more than a dozen times just to control the contraction of the surface layer of mental power and the inner layer of magic elements. After she achieved this, how to keep the endurance of the surface layer of mental power at a critical state was another point that Lido needed to explore and practice repeatedly.

During practice, the high-pressure water ball often explodes beyond the critical value, or a hole is opened too far away from the critical value, resulting in the water column having insufficient pressure and unsatisfactory power.

Moreover, after the hole is opened, as the water inside the water ball sprays out, Lido has to control the surface layer of mental power and the inner layer of magic elements to continue to contract, so that the remaining water in the water ball still maintains the same pressure. To maintain this dynamic balance, it is a big challenge for Lido's control and calculation ability!

At the same time, Lido also had to calculate whether the high-pressure water ball could last until the meteorite fragments were peeled off the mountain wall, so it would be best to leave some margin.

Therefore, we need to make a comprehensive consideration of the thickness of the surface layer of mental power and the amount of water initially wrapped around it.

Lido's knowledge of science in her previous life was quite average. Even though her thinking speed, memory and thinking ability have been enhanced in this life, without a foundation, it is equivalent to no knowledge for Lido.

So we can only rely on repeated attempts to eliminate wrong options.

As a result, the number of experiments increased. Of course, the number of failures also increased. The water in the cave was no longer calm, but kept turbulent.

Even though the size of the water ball was insignificant compared to the amount of water in the entire cave, and the noise caused by the explosion was mainly concentrated in the water at the bottom of the cave, Lido was still worried that it would alarm the high-level monster above.

But Lido was really lucky today. The high-level monsters were completely silent. Could it be that they were really hibernating?

After countless failures and when Lido's mental strength was mostly depleted, she finally managed to get the high-pressure water gun out!

Lido controlled the high-pressure water ball and came to the mountain wall where the meteorite fragments were located. She opened a hole, and a thin column of high-pressure water sprayed out. Although it was not fast, the mountain wall was still cut open like tofu by a knife.

What Liduo did was to cut a slanting line on the mountain wall on both sides of the meteorite fragments, which was more than half a meter deep. In her mental perception, the water gun avoided the location of the meteorite fragments.

Then Lido cut another line on the upper and lower walls of the mountain. Since the meteorite fragments were located in the upper part of the cave, under the dual effects of gravity and Lido's mental power, the cut stones quickly broke away from the mountain wall and sank to the bottom of the water.

At this time, the meteorite fragments were almost exposed. Although they were still wrapped in rocks, Lido didn't need them to reveal their true form now. She just needed to separate them from the mountain wall and make them large enough to pass through the spring channel.

With the high-pressure water ball in hand, the meteorite fragments were quickly separated from the mountain wall. Lido used a high-pressure water gun to slightly trim the edges, turning it into an inconspicuous stone ball, and then used the spiritual thread to drag it into the spring channel.

There is still a small half of the high-pressure water ball left. I will seal the pinhole with it and take it away. It will be useful when I pull the stone ball out of the ground later.

So Lido began to walk along the spring water channel towards the Huashi River, and the stone ball and high-pressure water ball also followed in the spring water channel.

When they were a little further away from the crater, Lido used a high-pressure water ball to make a hole in the ground and took out the stone ball. In order to prevent the magic elements from leaking to the ground, Lido sealed it back as it was.

After so much hard work, the second part of the new school year's opening is finally here! Sprinkle flowers!
