Coming out of the Nine Chambers of Commerce, Jiang Ding checked the invitation in his hand again.

Unnamed, there is a faint black dust nine mountains pattern inside, the time is three years later, but the location has not been decided, saying that it will be revealed on the invitation at that time.

According to the past practice, in an inconspicuous place in the Great Sun Sword City, or a hut, or an underground, or a teahouse, a hidden auction venue will be temporarily built by means of space, and a teleportation escape venue.

However, if it is said to be an underground auction, it must also be secretly supervised by the Great Sun Sword Sect.

It's just that he follows the ruling strategy that is better than sparse and puts it under his nose.

"It's still three years before ...... start"

Jiang Ding didn't like to stay in a place where big forces gathered, and he didn't like to have any friendship with people, so he called him a brother and a brother, flew out of the Great Sun Sword City for tens of thousands of miles, and found a random place to live in seclusion and lurk.

Enter the standby state, do not do much, do not touch, cause and effect do not touch.

……

Under the three-thousand-meter-high Sun God Tree.

Jiang Ding opened his eyes, logged on to the Xianmen website, searched for keywords such as 'synthetic materials', 'sacrificial refining magic weapon', 'sacrificial refining baby treasure', read one literature after another, and after a few months, he had a general understanding of the development of Xianmen's material science.

Of course, just to understand, to know the state of development, what are the results at the forefront.

Go deeper, but you can't.

This requires a lifetime of effort from many immortal cultivators, and it is extremely complicated.

Not to mention anything else, many Yuanying-level and god-level articles may not be able to read and understand them in a few years.

"The highest achiever of Xianmen materials science is the king of ten thousand machines."

"He is the mentor of Jin Lingfeng, the teacher of Rongjin Jinjun, the teacher of the teacher."

Jiang Ding's gaze swept past the sentence at the end of the article, 'This article does not need to refer to any literature in the realm'.

"This old-timer is far from the same era as him, a scholar of Xianmen Materials Academy, at least four or five thousand years old, almost all his friends and relatives of the same generation are gone, and he has been in retreat for a long time, and it is estimated that he has not appeared in public for one or two thousand years."

"Even if you make an appointment to meet, it's an honor to meet the old-timers once in a hundred years."

"But...... I know where he is now. ”

Jiang Ding waved his hand to put away the Sun God Tree and put it in the center of his eyebrows.

The trunk of the Shenmu branch disappeared, and only a huge steel battleship remained in the original sky, pulling the Great Sun Light to refine the hull and the fourth-order Magnetic Cloud Splitting Star Cannon.

The Lingzi Engine Furnace was running non-stop for a moment, smelting many second- and third-order heavenly and earthly treasures in the fuel tank, and refining the Tiangang Prohibition of the electromagnetic system within it.

"Yunri, are you going to the library?"

Jiang Ding asked.

In the Xianmen, he set up quite autonomous permissions for the Chaori ship spirit, and did not force anything.

"Commander, you go by yourself, I still have to go to the battleship maintenance center to practice the Tiangang ban, one of the stages needs the support of your divine soul, I will inform you when the time comes."

Ship Lingyun said crisply.

She is always busy in the Xianmen, refining the magnetic cloud splitting star cannon, refining the Dyson sunglasses drone, refining the hull, smelting various magic weapons and even baby treasures as materials, and so on.

"Okay."

Jiang Ding didn't care about her, the blue light of his body flashed, the tearing space disappeared, and the light faintly overflowed with the edge of the sword, and the speed was a little faster than usual.

This is the preliminary result of the third-order electromagnetic system sword escape.

Decades ago, Yu Qianzi promised to help him improve the research and development of the third-order electromagnetic system sword escape for some reasons, even if the relationship between the two parties has dropped to the freezing point in recent years, she still has not broken her promise.

She didn't respond to other questions, such as swordsmanship, but she could respond in a timely manner to the research and development of the third-order sword escape.

Jiang Ding's choice was to integrate other swordsmanship things into the sword escape and ask her.

It is expected that in another 20 years, the third-order electromagnetic system sword escape will be successfully developed.

If successful, the legacy of research and development experience will give great inspiration to those who come after it, and many of the experiences can be applied directly, without having to start from scratch.

Fly over some time and come to the Xiandu Library.

The surrounding area is bustling, the elderly, youth, children, teachers, farmers, soldiers, businessmen, etc., people of all ages and statuses are reading and walking through the library, there is no noise, and they all try to keep it quiet.

There was no priority passage for high-level monks, Jiang Ding honestly followed behind a sixth-grade child, swiped his card, and walked briskly to the high-level immortal Dao knowledge reading area in the second half of the Xiandu Library.

High-level immortal dao knowledge is dangerous in itself.

There are a lot fewer people here, most of the people who come and go are Jindan monks, and occasionally there are one or two Zhuji monks who are also cautious, stopping every few steps to stop to read the library reading manual, and compare their current behavior, so as not to inadvertently come into contact with high-level knowledge and cause themselves to go crazy.

Deeper, fewer people.

Most of the people who come and go are Yuanying Zhenjun, and the probability of knowing each other has been greatly improved, and there have been occasional intersections at academic conferences.

When Jiang Ding saw it, he often bowed slightly and greeted him silently.

Finally, I came to the very deep place in the library, where the Yuan Ying Zhenjun was rare, and occasionally, they were often cautious.

Jiang Ding stopped at the gate of a palace that was all over gold.

Golden Palace!

The second sequence of the collection, the beautiful picture of the Golden Emperor's bath.

That's right!

At other times, all the Heavenly Monarch seniors scattered in all directions, retreated, studied, and waited for leisure to be rare, but as soon as the immortal art appeared, they all exploded, and they were soaked here all day long, and rarely went out.

If you want to meet people, just come here and rummage around.

Walk into the palace with a strict forbidden formation.

"It's not like that!"

"You old thing confused? How could Kim be like this? Don't mislead others, hurry up and admit your mistake to Lao Tzu! ”

"Fart ......"

It's a noisy place, like a vegetable market, and a few places have been opened and ping-pong.

Jiang Ding was not surprised.

These old-timers will also stand up in front of the juniors, and they look respectful.

It's not so easy to talk when you meet your peers, and after many years of experience, maybe you remember clearly when you were a child peeing your pants on the battlefield.

But they weren't just brawls.

The comprehension of the two parties is deviated, one side thinks so, the other thinks that, so they directly use the same divine sense and mana, and use their own comprehension to do it, and whoever wins is more correct-

Just more correct.

Before the exact theorem and formula were born, even if a person was beaten on the ground, it was impossible to be convinced.

When they were fighting, the Yuanying Zhenjun who was brought in on the side trembled and fled far away, for fear that they would be injured by mistake.

Jiang Ding rummaged through the piles of people everywhere for a long time, and finally found his goal.

A person more than one meter tall, the limbs of the mechanical arm can be retracted, the whole body is made of some kind of high-grade metal, and the head is made of ...... Well, without a head, it's just a computer screen.

The whole looks like a body, limbs, hands and feet growing under a computer screen.
