The spell Doro's use didn't really make her smaller.

Li Yu didn't expect that Doro's spell would involve space. In Li Yu's view, Doro's spell just narrowed the space it occupied, and it could be regarded as a special space expansion technique.

I have to say that Doro's spell is a trick, and spells can always do something tricky. It's just a trick, and you have to pay some price, so her spell also has a lot of problems, and the biggest problem is that this spell consumes a lot of mana.

In other words, Doro's spell doesn't last long.

With Doro's strength, she could maintain the spell for three hours, and when the time was up, she would have to disarm the spell.

Knowing the principle of this spell, then Li Yu has more ways to optimize this spell.

As soon as she saw Li Yu's expression, Doro knew that Li Yu's research had come to fruition.

"Li Yu, do you understand the principle of my spell?"

"Well, that's right, your spell, I have to say it's very thoughtful!"

"Can you improve it?"

Doro's eyes were full of anticipation, and it seemed that she also knew that her spell had a big flaw.

"I can improve your spells, but my improved spells will be much more difficult to cast!" Of course, Li Yu will not say the best solution all at once, because then it will not be worth it.

The most important thing is that this is only the first official meeting between Li Yu and the Blue Bird Clan, and it is not yet time to make friends.

In other words, the Blue Bird clan must pay some price in order for Li Yu to tell the solution. Of course, the Blue Bird family can also study on their own, and I believe that they can eventually study the optimization plan, but the time required cannot be determined.

Doro may not understand the middle of this, but the elder of the Blue Bird Clan, he understands.

Li Yu's strength, he saw it last time. Because of Li Yu, they had to modify the high-dimensional spatial coordinate signal of the Holy Land. It can be seen that Li Yu's strength cannot be underestimated.

However, although Doro is young and not very sensible, she is not stupid, after listening to Li Yu's words, she rolled her eyes and told the people present the spell she had studied.

In this process, the elders of the Blue Bird Clan did not stop it. Really speaking, this spell is also useful for huge inhumanoid creatures, and for Li Yu and them, this spell is not of much value.

Therefore, this spell had no secret value for Li Yu and them at all.

When everyone else began to study the spells that Doro had researched, the elders of the Blue Bird Clan found Li Yu and chatted.

"Speaking of which, this is also the second time we have met, I didn't expect that after such a short period of time, your strength has improved so much!"

The elder of the Blue Bird Clan was not complimenting Li Yu, he really felt the changes in Li Yu's strength.

"Excuse me, what is the purpose of your visit to Xinghai this time? If we can, we're here to help. ”

Li Yu's heart moved, "We came to Xinghai this time, there is indeed something, and it is only by the way to visit Doro." ”

"Oh!? I wonder if we can help? ”

Of course, there is a reason why the elder is so enthusiastic, Li Yu obviously saw the principle of Doro's spells, and there was an improvement plan,

It is definitely inappropriate to ask Li Yu to say the plan rashly, and it is even more inappropriate to use strong words.

In this case, equivalent exchange is the most suitable option. When Li Yu and the others came to Xinghai, they definitely didn't come to visit Doro, and the elders saw this very clearly.

So Li Yu, what are they doing in Xinghai?

No matter what it is, the Blue Bird Clan, as the head snake of the land, will definitely be able to help.

As long as the Blue Bird Clan can help, wouldn't it be natural to let Li Yu help solve the problems with the spells that Doro had researched?

"The purpose of our coming to Xinghai is to test a research, but the object that needs to be selected for this test has relatively high strength requirements, so we can only come to Xinghai. Because only here in Xinghai can there be experimental objects that meet our needs. ”

It turns out that Li Yu and their purpose in coming to Xinghai is for this? If you need a strong test object, the Blue Bird Clan can definitely meet the needs, who can say that the Blue Bird Clan is not strong?

However, the elder did not immediately propose to let the Blue Bird clan take on the test object.

"If that's convenient, can you tell me what your test is?"

Li Yu thought to himself, it seems that this elder really wants to take on the role of the test object, but he still needs to determine whether the laboratory test will cause any bad consequences to the Blue Bird clan.

If the consequences of the test are too much for the Bluebird clan to bear, I believe that the elder will not agree to become the target of the test.

If the consequences of the test were within the tolerance of the Blue Bird Clan, the Elder would definitely agree to become the test object of the laboratory, and the price would be the improved spell.

Li Yu also just came up with the idea of making the Blue Bird clan the object of the test. Before coming to Xinghai, the lab's plan was to visit Doro, and then let Felenon reunite with Doro here in the Blue Bird Clan, and then the lab would find a suitable test object and conduct the test.

When the test was over, he hurried over and took Felenon away, and then slipped away.

The test is likely to cause great damage to the test object, so don't run and other troubles.

It's just that Doro's spell gave Li Yu one more choice, that is, to let the Blue Bird Clan voluntarily become the test object, and only need to control the power of the energy matrix without causing harm to the Blue Bird Clan's testers, I believe they will be happy to become the test object.

"We've worked out a defensive system, and we need some powerful civilizations to test it to perfect its performance."

"A defensive system?" Forgive the elder for not understanding what Li Yu meant, because he hadn't heard of such a thing as an energy matrix.

"Well, you can think of it as a magic circle or something, just like your high-dimensional space spells, we designed a defensive spell that needs to be tested."

A smile appeared in the elder's eyes: "I suppose the defensive circle you designed is not just a defensive circle, right?"

"What you said is right, pure defense, that is a long-term defense, this is the oldest understanding of our civilization. Therefore, we also have a saying that offense is the best defense. ”

"It's just that we didn't do it so extremely, the main mode of operation, or defense."

"I have one last question, and if there are no problems, I think the Blue Birds would be happy to take on the role of test subject."

"How dangerous is this kind of test?"

What the elder meant, Li Yu understood, the Blue Bird Clan could not risk the loss of the clansmen to conduct the test.

Li Yu also understands this reason, because the Blue Bird Clan seems to be powerful, but they have a fatal problem, that is, the number of their clansmen is too small.

Although there is no specific data, Li Yu believes that the number of blue birds is estimated to be less than the population of a province in China.

In this case, every clansman is very important to the Blue Bird Clan.

"There is definitely a danger, but the danger is controllable."

At this time, the elder was relieved.

"Well, I think we, the Blue Birds, would be happy to take on the test for this character."

Li Yu smiled with satisfaction and said, "Ha! This has helped us a lot. As a token of appreciation, I'm going to give you a small gift to show our gratitude! ”

After speaking, Li Yu took out one of his improved plans, which could make Doro's spell last for a month.

At the same time, Li Yu also hinted that after the test is over, he will study the improvement plan for Doro's spell that can be used permanently.
