Chapter 501: The world's strongest infrastructure legion is born!

Tianwen Academy.

Because of the secret inspection, Yao Yun and his group were very low-key and entered Tianwen Academy without disturbing anyone.

Today, the college is divided into three parts.

The first part is a circle of exchanges and discussions formed by Qi Refiners from all over the world to pilgrimage to Rune Tao Monument. Tianwen Academy welcomes Qi Refiners from all over the world who come to Tianwen Academy to exchange Rune Tao. Not only does it publish all the basic runes in the Rune Tao Monument, but it is also updated from time to time to guide Qi Refiners from other places to learn and comprehend.

The second part is the school where Xiguo is a serious school to cultivate talents from all walks of life.

The third part is the Rune Laboratory, which is the part that Yao Yun values ​​the most. It is the main force in Tianwen Academy's research on rune methods. The core of the core belongs to the Xiguo Secret Department.

The teachers and students here will study, experiment, summarize, and summarize countless times every day, and through repeated practices, we will deeply understand the way of runes.

The teachers and disciples of the Rune Laboratory may not be as good as those of the high-level Qi Refiners outside, but they have the deepest and most detailed understanding of the basic runes and even the entire rune way.

This is not surprising. Although the cultivation level of foreign Qi Refiners in Tianwen Town is unfathomable and they have learned a lot of witchcraft secret techniques, most of them "know the truth but not the reason". The secret techniques of witchcraft secret techniques they have learned are passed down from the master. How the master communicates with them and how they learn, they do not understand the mystery.

Some people are smart and modify the runes in the witch cursive secret technique to use it to improve the secret technique of the witch cursive. However, their ideas are good, but the reality is cruel. The runes in the talisman secret technique are extremely exquisite. If you don’t know how to modify them, the final result will naturally be failure - a magical and powerful secret technique will turn into a bunch of ghost-painted peach talismans.

There are also many powerful Qi Refiners who rely on their supernatural understanding to occasionally gain something while using their own ideas to improve the magic spell secret techniques. In the eyes of many Qi Refiners, they can be regarded as a master.

This is also why the Qi Refiners from other places were extremely excited when they first saw the basic runes. Because the Rune Way provides Qi Refiners with an idea to understand their own magical magic.

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

The teachers and students in the rune laboratory established by Yao Yun followed Yao Yun's guidance and started researching the characteristics of each basic rune. Through countless experiments, they compared the way of runes, from small to large, from simple to difficult.

Although the achievements made at the beginning were not that great, they were not as good as those of foreign qi refiners, as long as they persisted, they would explode sooner or later. By then, their energy would be beyond imagination.

Yao Yun believed in this, but he often did not expect that the result would come so quickly, a secret technique to turn soil into hard rocks.

"King, Prime Minister, please see."

Under the leadership of Yanzhe Aqi, Yao Yun and Sun Muyue and their group soon entered the secret cave behind Tianwen Academy.

The beast oil lamp in the cave was always lit. At the warning of Yanzhe Aqi, a group of Tianwen Academy brothers made of bamboo strips to get a pile of half-dry and half-wet soil, and poured it on the ground casually.

Yanzhe Aqi: "King, this is ordinary soil, please check it out."

Yao Yun and Sun Muyue looked at each other, and it was indeed the most ordinary soil. Then the two nodded and signaled their disciples to continue.

Then the disciples spread the soil flat on the ground, forming a thick layer, and then gave up after simple compaction.

After preparing for the work, one of the disciples muttered a word, and his hands were filled with vitality, yellow and orange, like rippling waves, jumped from his hand into the dirt block and sank into it.

After the fluctuations of the yellow-coloured vitality passed, the originally not-solid earth-yellow earth-cup block transformed into a yellow-coloured hard rock, which looked sturdy and durable.

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

There are many Qi Refiners who have seen in the past few years. Compared with this, it is more magical and powerful means. Yao Yun once heard from the second elder Wu Tong that he had seen a fifth-grade Qi Refiner using his magical power to turn a swamp into scorched earth and a stubborn stone, and his methods were great.

However, the two of them were surprised at this moment, but they were heartbroken. It was not because of anything else, because the person who used this method was not a fifth-grade Qi Refiner, and they were not even considered a Qi Refiner. They were just a witch boy who had just cultivated the power of the mind.

"It's done?"

"Report to the Prime Minister, that's right!" Yanzhe Aqi reported, and then bowed and said, "Please review the king!"

"Good!" Yao Yun was the first to walk up. The touch of one foot was quite strong. He stomped his feet casually, and the ground was not broken. It looked very durable, comparable to the cement concrete of his previous life.

Yao Yun casually took the weapon from the soldier beside him and stabbed it hard, without adding mental power, nor did he use his vitality. However, his power was not small, enough to make a barbarian wearing animal skin die through his chest.

However, with such a sword, there was only a small pit on the earth and rocks, without cracks or piercing.

It is no less than the steel and concrete in later generations!

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

The rune earth and stone vacated by Tianwen Academy now seems to be more magical and powerful. The only question is how long the earth and stone can last.

The first witchcraft that Yao Yun learned when he was a witch boy was [Golden Character Curse]. Its effect was to strengthen weapons and make them sharp and solid, but had a very short time effect.

If the earth and stone in front of you are the same, then you will be in vain.

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

Yanzhe Aqi did not answer immediately at this time, but pointed to the disciple who had just used the rune secret technique and said, "King, the idea of ​​the earth and stone rune secret technique was proposed by Xiao Niba. He made the greatest contribution and had the most say in this rune secret technique."

When Yao Yun heard "Little Niba", he was not surprised. Many people from poor backgrounds, without names or surnames, mostly called common objects around him, and were rustic.

"Little Niba." Yao Yun turned his head to look at him, and then nodded frequently: "You are doing well, don't be nervous. I ask you, how long can this soil and stone last?"

Xiao Niba was a little flattered and stuttered: "Return...Return the king, it is normal...it can never be damaged. This secret technique only serves as a guide and fusion effect. The strength of the earth and stone does not require the maintenance of vital energy, so using this secret technique will not consume much mental power and vital energy..."

Speaking of the rune, Xiao Niba stopped stuttering, talked endlessly, his face turned red, and he was very excited.

When Yao Yun heard this, he immediately looked surprised and surprised. He originally thought that this earth and stone could last for a year or two, but after Xiao Niba said that this earth and stone rune technique is not only powerful and lasting, but also does not require much energy to cast the rune secret technique.

In this way, the value of this [earth and stone] rune secret technique is immeasurable and can be regarded as an infrastructure artifact.

At the first moment, Yao Yun had an idea in his mind: pass this [earth and stone] rune secret technique to the army of ghosts under his command, and then the most powerful infrastructure legion in the world was born.
