Chapter 501: The World's Strongest Infrastructure Legion is Born!

Tianwen Academy.

Because they wanted to inspect secrets, Yao Yun and his party were very low-key and entered Tianwen Academy without alarming anyone.

As asked today, the college is divided into three parts.

The first part is the exchange circle formed by the pilgrimage of Qi Refiners from all over the world, Tianwen Academy very much welcomes fellow Qi Refiners from all over the world to come to Tianwen Academy to exchange the way of runes, not only announcing all the basic runes in the Rune Dao Monument, but also updating them from time to time to guide Qi refiners from other places to learn and comprehend.

The second part is the school where Xiguo Zheng'er Bajing cultivates talents in all aspects.

The third part is the rune laboratory, which is the most important part of Yao Yun, and it is the main force of Tianwen Academy's research on the way of runes, and the core of the core belongs to the secret department of the Xi Kingdom.

The teachers and students here will study, experiment, summarize, and summarize countless times a day, and gain an in-depth understanding of the way of runes through practice again and again.

The cultivation of the teachers and disciples of the Rune Laboratory may not be as profound and detailed as the high-level Qi Refiners outside, but their understanding of the basic runes and even the entire rune path is the most profound and detailed among mortals.

This is not surprising, although the cultivation of the foreign qi refiners in Tianwen Town is unfathomable, and there are a lot of witchcraft secret techniques they have learned, but most of them "know what it is, but they don't know why", and the witch spells and secret techniques they learn are all passed on from the master, how the master communicates, how they learn, and they don't understand the mystery.

Some people think they are clever and modify the runes in the witchcraft to improve the spell spell, but the idea is very good, but the reality is very cruel, the runes in the spell spell are extremely subtle, if you don't know how to change blindly, then the final result is naturally failure - a good and powerful secret art, stunned into a bunch of ghost painting peach talismans.

There are also many strong qi refiners with their superb understanding, in the process of performing witchcraft spells again and again, they occasionally gain something, and improve witchcraft spells with their own ideas, which can be called everyone in the eyes of many qi refiners.

This is also the reason why the foreign Qi Refiners were extremely excited when they first saw the basic runes, because the way of the runes provided the Qi Refiner masters with an idea to understand their own witch spell secret arts.

Not to mention anything else, there are many Qi Refiners who have a flash of inspiration and have benefited a lot.

The teachers and students in the rune laboratory established by Yao Yun followed Yao Yun's guidance and began to study the characteristics of each basic rune, and studied the way of runes through countless experiments and comparisons, from small to large, from simple to difficult.

Although the achievements achieved at the beginning were not so great, they were not as good as the wonderful hands of the foreign qi refiners, but as long as they persisted, sooner or later there would be an outbreak, and by that time, its energy would be beyond imagination.

Yao Yun was convinced of this, but he often didn't expect that the results would come so quickly, a secret technique that turned dirt into hard stone.

"Your Majesty, Prime Minister, please see. ”

Under the leadership of Yan Ah Qi, Yao Yun and Sun Muyue and their party quickly entered the secret cave in the mountain behind Tianwen Academy.

The beast oil lamp in the cave was always on, and at the suggestion of Yan Ah Qi, a group of Tianwen Academy disciples made a pile of half-dry and half-wet soil from a basket made of bamboo strips, and poured it on the ground very casually.

Yan Ah Qi: "King, this is ordinary soil, please take a look." ”

Yao Yun and Sun Muyue looked at it one after another, it was indeed ordinary soil, and then the two of them nodded one after another, signaling the disciples to follow.

Then the disciples spread the soil on the ground, a thick layer, forming a square, and then after a simple tamping, they gave up.

After making preparations, one of the disciples had words in his mouth, and his hand was even more energetic and condensed, yellow, orange, like a sparkling wave, and jumped from his hand into the dirt cube and submerged in it.

After the vitality fluctuations of yellow-orange-orange passed, the original earthy yellow earth block that was not very compact was transformed into an earthy yellow hard stone, which looked strong and durable.

This scene is actually nothing in the eyes of the Qi Refiner.

Whether it is Yao Yun or Sun Muyue, there are also a lot of qi refiners over the years, compared to this more magical and powerful means are commonplace, Yao Yun also heard the second elder Wu Tong say that he has seen a five-grade qi refiner use his magical power to turn a swamp into scorched earth and stubborn stones, and the means are good.

However, the surprise on the faces of the two of them at this moment was from the bottom of their hearts, not because of anything else, it was precisely because it was not a fifth-grade qi refiner who used this method, not even a qi refiner, but just a witch boy who had just cultivated the power of the mind.

"It's finished?"

"Returning to the Prime Minister of the State, exactly!" replied, and then bowed down and said, "Please review the king!"

"Good!" Yao Yun was the first to walk up, the touch of stepping on it was quite strong, stomping his feet at will, the ground was not broken, it looked very durable, and it was a fight with the cement concrete of the previous life.

Yao Yun casually took the weapon from the hand of the armorer on the side, and stabbed it hard, without attaching the power of the mind, let alone using the vitality, but the power was not small, enough to make a barbarian wearing animal skin die through his chest.

However, such a sword pierced only a small pit in the earth and stone, and there was no crack or piercing.

Compared with the reinforced concrete of later generations, it is not much better!

Yao Yun was immediately overjoyed, he wanted to get the cement out before, but because of his life experience, he didn't know much about cement, he only knew that the soil method cement was made of limestone, clay and other things, and he didn't know the specific situation.

At the moment, the rune earth stone poured out by the Tianwen Academy seems to be more magical and powerful, and the only question is how long this earth stone can last.

The first witchcraft that Yao Yun learned when he was a witch boy was the [Golden Spell], which had the effect of strengthening the weapon and making it sharp and strong, but the time limit was very short.

If this is the case with the soil and rocks in front of you, then you will be happy in vain.

"How long can this earth and stone last?" Yao Yun asked.

Yan Ah Qi did not answer immediately at this time, but pointed to the disciple who had just performed the rune secret technique and said: "Great King, the idea of the earth and stone rune secret technique was put forward by Xiao Niba, and he has made the greatest contribution and has the most say in this rune secret art. ”

When Yao Yun heard "little mud", he was not surprised, many people from poor backgrounds, without names and surnames, most of them casually called the common objects around them, and they were rustic.

"Little mud. Yao Yun turned his head to look at him, and then nodded frequently: "You did a good job, don't be nervous, ask you, how long can this earth and stone last?"

Little Mud was a little flattered and stammered, "Go back to ...... Back to the king, is... Under normal circumstances, it can never be damaged, but this secret art only plays a role in guiding and fusing it, and the solidity of the earth and stone does not need to be maintained, so it does not lose much mental power and vitality when performing this secret art......."

Speaking of the way of runes, the little mud stopped stammering, gushing endlessly, his face flushed, and he was very excited.

When Yao Yun heard this, there was a look of surprise in his eyes, he originally thought that this earth and stone would have great practical value if it could last for a year and a half, but listening to Xiao Mu's words, this earth and stone rune technique was not only powerful and long-lasting, but also did not require too much vitality to perform the rune secret technique.

In this way, the value of this [Earth and Stone] rune secret art is immeasurable, and it can be called an infrastructure artifact.

For the first time, Yao Yun had an idea in his mind: to pass on this [Earth and Stone] rune secret technique to the army of ghosts under his command, and then the most powerful infrastructure army in the world was born.

Hundreds of thousands of infrastructure maniacs!
