Golden stone.

A type of mineral.

It is also a material that Taiwu needs to refine and absorb.

Similar to the original search for wood, Li Hongru also searched for some metals, but many of them did not indicate anything.

Just as Taigo did not recognize copper coins and silver as wealth, Taigo was also picky about gold and stone.

Only a few metals that meet the specifications may be recognized.

Li Hongru picked up the black object, and a heavy feeling suddenly came.

It is an irregularly shaped object, somewhat like the prototype of a sword hilt.

A familiar feeling came, and Li Hongru immediately took a bite of this black object.

The pain of his nearly broken teeth cleared his mind.

Li Hongru knew that this was due to the demonic influence of the iron-eating demon beast, and his habitual actions came again.

Whenever he is close to metal or holding metal objects in his hand, Li Hongru wants to take a bite to try the situation (taste).

"This is iron essence, not something to eat, you don't have to break your teeth."

The sound of teeth rubbing against metal made Wang raise his head vigorously.

He glanced at Li Hongru rather strangely, and then introduced the items.

"Iron Spirit?"

"Refined iron is refined by a hundred tempers, and iron essence is obtained by thousands of hammers, this is the material for building strong soldiers and magic weapons, and you are afraid that it is rare outside."

"I haven't seen it."

Li Hongru touched his aching teeth.

The bite is constant, not to mention devouring refining and absorption.

But it was not bad to accidentally learn the source of the gold stone.

In order to meet Taiwu's gold and stone specifications, the metal quality requirements are relatively high, and now I finally know a concept.

This is not only a test of the source of obtaining the gold stone, but also a test of his mouth teeth and stomach refining power.

"This iron essence looks inconspicuous, but it can give the sword the ability to sharpen iron like clay, and its price is not cheap, just the small piece in your hand, at least ten taels of gold."

"So expensive!"

"Yes, these are all rare materials provided by the Equipment Division, and each piece is extremely precious."

Wang Dali is a wonderful person, and he likes to beat around the bush when he speaks.

This is probably thinking that he is rummaging through things.

As soon as the other party said it, Li Hongru immediately put away his hands and feet and focused on the carving of the crystal.

At this time, the crystal already had the basic rudiments of the convex lens.

These are two rare large transparent crystals from the Instrument Division, which were directly requisitioned for experiments.

There are very few impurities in the crystal, and if Wang Da is more skillful, he can also directly remove the impurities in some areas.

Although it has the aid of demonic powers, it is obviously a water-grinding effort that takes a long time.

Whether it meets the requirements is only clear to Li Hongru.

He's not going to be here for a short time.

Looking at the workshops outside, Li Hongru was also fortunate to have a backstage, otherwise he would be favored by the Equipment Division, and his future life would have to change direction.

The waiting in the workshop was quite boring, and after waiting, Li Hongru recited the words and began to recite the "Five Classics of the Spiritual Vein".

It's not a waste of time to memorize more and delve into more.

This will allow him to rely on Taiwu to improve his initial progress in cultivation, and he will also be able to continuously strengthen his learning ability and avoid relying too much on Taiwu.

Li Hongru even started his cultivation according to the method of "Five Classics of Spiritual Veins".

A little cyan shimmer through his body, his mind was calm, and his ears were much sharper, and he could hear some subtle sounds that he usually ignored.

"If you don't borrow or borrow, why should Lord Xu be strong."

"Now he is the only one who understands the principle, if something goes wrong, you can't let me run back from Bingzhou, right?"

"Do you want treasures and people? My students are still studying too much. ”

"It's also a good thing for young people to see the outside, and it's not a loss to go to the state to see, not to mention that the community should be the most important."

"He has no defense, and if he goes to those treacherous places, he will die."

"I will definitely take care of him like a parent, and I will not lose him, let alone put his life in danger."

"Your ......"

Outside the workshop, Xu Maogong was haggling with Wang Fuchou.

This is an attempt to requisition him.

Li Hongru pricked up his ears.

He lived a good life in Chang'an City, went to school every day, endorsed books every day, practiced every day, lived a good life, and didn't want to join the army at all.

Even if it was requisitioned, he just wanted to travel with the children of Taixue's family.

It is a safe security group, and it is also a heavenly group that makes contributions to oil and water, which can make many people gilded.

Li Hongru has long been ready to learn both hands, and wait until the right time to make some extra money.

But Xu Maogong disrupted the plan.

Wang Fuchou was a little overwhelmed at this time.

The official level crushed people to death, not to mention a general like Xu Maogong, who was close to the king.

The other party has the military power of a state, not an honorary position, and belongs to a real fierce general.

"He's still young, I'm afraid he can't withstand this kind of toss."

"Chicks go through wind and rain to become eagles, and Dr. Wang's greenhouse helps to become a big tool."

"I lost a student in the wind and rain, and it hasn't been two months since I started."

"That's the person you left down to follow, if you follow me, how can he have an accident, it's not that I am bragging about it, there are only a few people in Datang who can beat me, and no one can kill anyone I want to protect."

……

"It's up to him to do that himself."

"It's hard to disobey the teacher's order, just let Brother Fuchou agree."

was assured by Xu Maogong's chest for a while, Wang Fuchou was finally irresistible.

Although Xu Maogong persuaded people with reason, in fact, Wang Fuchou could not resist.

Salute first, then soldier.

From the beginning of Xu Maogong's contact with Li Hongru, Li Hongru was very clear about the other party's methods.

Coming slowly, it's hard to refuse.

After convincing Wang Fuchou, the roadblock, it became an easy task to persuade Li Hongru and the Li family.

"Pills!"

Li Hongru sighed secretly.

The leisurely little days are coming to an end.

A telescope gave him a chance, and at this time it also had some bad consequences.

I thought that Xu Maogong was just making a telescope, but I didn't expect that the other party would even pack people and take them away.

He drew the schematic diagram of the telescope and made a lot of explanations, just to get it out of his mind.

But Xu Maogong seems to have other ideas.

Either he didn't want to leak secrets, or he was guarding against some people, or he didn't want to make a mistake when the time was urgent, Xu Maogong didn't find someone else to replace him.

Taking things with people would limit the knowledge of the telescope to a very small extent.

Without leaks, there is also an opportunity to strike at the enemy.

Li Hongru thought about it for a while.

When he heard a soft knock on the door, he immediately frowned and walked out.

"Little friend Li Hongru, are you interested in going to our state to have fun?"

Xu Maogong's eyes were smiling, but like a strange Shu Huang who tempted Lori, there was a sense in his eyes that he had to play.

"Teacher, how much can I be worth now?"

Li Hongru sighed.

He also has a backer, and it is impossible for him to do voluntary labor.

Since he couldn't refuse, Li Hongru still wanted to get some due treatment.

"You know everything?" Wang Fuchou said strangely.

"You're talking a little loud, you can hear it clearly in the back room."

"How much am my student worth?" Wang Fuchou asked Xu Maogong.

It was only at this time that Wang Fuchou finally felt that he could give Xu Maogong some problems.

Since he is so important as a student, he must be treated with important treatment.

If he is treated casually, he will be sent away directly, and then he will not be able to complain that he will make poems for Xu Maogong and give the other party a 'beautiful' name.

He can even find a few old friends and go to the emperor to pass on two sentences.

"I treat him like a parent," Xu Maogong muttered, "This should be the best treatment." ”

"How much money do you get?"

Xu Maogong's words are a bit exaggerated.

After suffering the loss of this governor, Li Hongru decided to ask clearly, after all, there is a saying in the "Book of Rites" that 'love the people is like a son'.

If it is calculated in this way, Xu Maogong treats him like a parent, and he is not the only one.

"Xu Dudu, you still give an accurate number, after all, my student family is poor and ugly and realistic, and I have to feed some food to do things."

Wang Fuchou scolded with a smile, but the implication was that it was not the case, and a definite number was needed.

"The literati are the most annoying!"

Xu Maogong looked at Li Hongru, and finally muttered, began to mention the treatment, and also bargained.

He was very bold in applying for money from the imperial court for Wang Dali, but when he arrived at the territory of the state, he was stingy when he needed to pay for his own place.
