After speaking, the white-haired old man did not explain any more. He waved his hand and an hourglass appeared. According to the speed at which the sand flowed down, it would take exactly ten days.
Seeing this, everyone did not dare to waste time, and they all closed their eyes to meditate.
"Array Heaven Book..."
After a moment, Lin Yu's eyes flashed with light.
Previously, he just memorized the contents of the scriptures without hesitation, but now he had the time to carefully comprehend them. After this insight and consideration, he immediately felt its extraordinary mystery.
This scripture is called the Formation Heaven Book. Although it is extremely long, in fact, it is just the introductory chapter of the Formation Heaven Book, which only records some basics of the formation method.
The way of formation, as an important branch of the path of cultivation, is naturally extremely broad and profound, and can be said to be mysterious and unpredictable. Even the most powerful saints cannot say that they have understood even one ten thousandth of it.
In fact, setting up a large formation with the help of formation flags is just the most basic method of using formation techniques.
A true formation master can directly use various mysterious terrains to set up large formations, and use the natural power of heaven and earth to exert the strongest power at the smallest cost.
It is said that some top formation masters can drive thousands of stars to form an extremely powerful formation using the stars and rivers of the universe as a formation map, which can kill even the strongest men above saints!
Of course, that level is not something ordinary people can achieve. Those who can achieve this can already be called heavenly masters and divine masters. Even in the entire Hongmeng God Realm, they will be admired and respected by countless powerful people.
.
In fact, it is impossible to get involved in that field just by relying on the introductory chapter of the Formation Heaven Book. After all, this is just an introductory chapter. Most of the records are about the methods of using the formation flags, and there are not many records involving various strange terrains.
.
However, even if it is just the method of using the formation flag, there are countless mysteries in it. If you want to understand it thoroughly, it will not be possible in a short time.
At that moment, Lin Yu suppressed the distracting thoughts in his heart and began to devote himself wholeheartedly to the heavenly book. With this understanding, he soon became completely immersed in it.
"Time is up!"
At a certain moment, the white-haired old man's voice sounded again, and Lin Yu suddenly woke up.
"Ten days have come. Next, it's time for you to take the third test."
Looking at the people who were still immersed in enlightenment, the white-haired old man looked calm. He pointed forward, and a shadow of the boundless starry sky appeared in front of everyone.
"In this third test, all of you will enter an independent starry sky space."
He said: "In this starry sky, there are a large number of starry sky robbers. What you have to do is to kill these robbers as much as possible. However, in the process, all of your cultivation bases will be sealed.
Unable to use divine power to kill the enemy!"
"What?"
"How can we kill the enemy without using divine power?"
The words of the white-haired old man immediately made many people's expressions change slightly.
"It's very simple."
The white-haired old man said calmly: "In this starry sky, there are a lot of rare materials. Although you can't use your divine power, you can use these materials to refine formation flags, arrange large formations, and use formation techniques to kill enemies.
.”
"The so-called talent and understanding can only be reflected in actual combat. This level is for you to apply what you have learned. Combined with what you have seen and learned from the previous level, see how much of your skills you can display!"
"this……"
The words of the white-haired old man made everyone look at each other in shock. Suddenly, one person said: "In that case, senior, how many enemies do we need to kill before we pass the test?"
"There are no specific standards. You just need to do your best. I will naturally make a judgment on whether you pass the test."
The white-haired old man's voice was very calm, and he said: "Okay, everything that needs to be said has been said, it's time for you to take the test!"
As he spoke, the boundless starry void transformed into a passage, and a powerful suction force erupted, immediately sucking Lin Yu and others into it.
Wow~
The next moment, Lin Yu was in the boundless starry sky. Not far from him, there was a ruined star with no life breath at all, just a large area of dark red ore.
"This is... dark magnetic ore?"
Lin Yu thought about it and immediately recognized this dark red ore.
Dark magnetic ore itself is not an extremely precious material. However, if there is a sufficient amount of dark magnetic ore, dark magnetic ore can be extracted, which is an excellent material for refining formation flags.
"Although you can't use your divine power to kill enemies, it shouldn't be a problem to use your divine power to refine ore."
Thinking of this, Lin Yu quickly took action. He quickly collected a large amount of dark magnetic ore, and then burned it with divine power. Three days later, only less than three hundred kilograms of hundreds of thousands of kilograms of dark magnetic ore remained.
A dark magnetic mine was formed!
"good."
Sensing the energy fluctuations emitted by the dark magnetic ore, Lin Yu couldn't help but nodded slightly, and then refined the dark magnetic ore into an array flag according to the method in the formation book.
Half a day later, he refined nine dark red formation flags, with countless divine patterns on the surface, and abundant energy fluctuations faintly flowing.
Whoosh whoosh!
At this moment, a sound of piercing the sky suddenly sounded, and then, dozens of iron cavalry quickly swept over and landed on the stars.
"Dark Magnetic Mine!"
The next moment, the leader's eyes suddenly burst into light.
After Lin Yu finished refining the nine formation flags, there was still some remaining dark magnetic ore. It was piled on the ground at the moment, emitting a dark red luster, which immediately attracted the attention of the cavalry leader.
"I didn't expect that in such a ruined star, I could still find the dark magnetic mine!"
His eyes fell on Lin Yu, with a sneer: "It seems that this dark magnetic mine was refined by this person. Capture him and use him as our mine slave!"
"give it to me!"
Behind him, a person shouted, and then quickly took action, controlling the strange beast under him. With strong winds, he appeared in front of Lin Yu in an instant, and then grabbed Lin Yu with a slap, trying to pick up Lin Yu.
!
"court death!"
Such an arrogant attitude immediately made Lin Yu's eyes become cold. He snorted coldly, and while retreating, he threw three formation flags.
Wow~
The three dark red formation flags buzzed, and the divine patterns on their surfaces all lit up, and then turned into blazing flames, immediately enveloping the man in them.
"ah!"
Accompanied by a shrill scream, in less than a breath, the man was burned to ashes and disappeared!
