Gold and stone.

A kind of mineral.

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

Like looking for wood, Li Hongru also looked for some metals, but there were no prompts for many metals.

Just as Taigo does not admit that copper coins and silver are wealth, Taigo is also picky about gold and stone.

Only a few metals that meet specifications may be recognized.

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

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

A familiar feeling came, and Li Hongru immediately chewed at the black object.

The pain of his teeth almost collapsed, clearing his mind.

Li Hongru knew that he was under the influence of the demonic power of the iron-eating monster, and his habitual movements came again.

Whenever you get close to metal or hold metal objects in your hand, Li Hongru wants to take a bite and try the situation (taste).

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

The friction between teeth and metal made Wang Dali raise his head.

He glanced at Li Hongru in a strange way, and then introduced the items.

"Iron Essence?"

"A hundred refinings can lead to iron, and thousands of hammers can lead to iron essence. This is the material for building strong soldiers and magic weapons. It is probably rare for you to go outside."

"I've never seen it before."

Li Hongru touched his teeth that were painful.

Even if you bite, you won't have to say that you can swallow, refine and absorb it.

But unexpectedly, I learned that the source of gold and stone is also good.

If we want to meet Taiwu's gold and stone specifications, the metal quality requirements are relatively high, and now we finally understand a concept.

This not only tests the source of metal and stone, but also tests the refining ability of his mouth, teeth and stomach.

"This iron spirit looks inconspicuous, but it can give the sword the ability to cut iron like mud. It is also expensive. Just the small piece in your hand can cost at least ten taels of gold."

"So expensive!"

"It is necessary, these are all rare materials provided by the Equipment Department, and every piece is extremely precious."

Wang Dali is a wonderful person and likes to beat around the bush when speaking.

This is probably because he was thinking that he was flipping through items.

As soon as the other party said this, Li Hongru immediately stopped his hands and feet in disappointment and gathered his eyes on the crystal carving.

At this time, the crystal has already had the basic prototype of a convex lens.

These are two rare large transparent crystals in the Equipment Department, which were directly requisitioned for experiments.

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

Although it has the help of demonic power, carving lenses is obviously a water grinding effort and it takes quite a long time.

Only Li Hongru knows whether it meets the requirements.

He will not be here for a short time.

Looking at the workshops outside, Li Hongru was fortunate enough to have a backstage, otherwise he would be attracted by the Equipment Department and his life would have to change direction in the future.

The waiting in the workshop was quite boring. Later, Li Hongru was lying in his mind and began to recite the "Five Classics of Spiritual Vein".

It is not a waste of time to recite more and study more.

This will allow him to improve his initial progress when he practices with Taiwu, and can also continuously strengthen his learning ability, avoid relying on Taiwu too much.

Li Hongru even started practicing according to the "Five Classics of Spiritual Veins".

The faint blue light penetrated his body, and his mind was in a state of concentration, and his ears were much more keen. He could hear some subtle sounds that he usually ignored.

"If you don't borrow, don't borrow, why should you force others to do anything?"

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

"You want treasures and people? My students are still studying in the Imperial Academy."

"It is also a good thing for young people to see outside. It is not a bad idea to go to Bingzhou to see it, let alone put the country first."

"He has no protection, and going to those dangerous places will be lifeless."

"I will definitely take care of him like a parent-child, and I will not blame him for his life."

"Your parent-child..."

Outside the workshop, Xu Maogong is bargaining with Wang Fuchou.

This is to recruit him.

Li Hongru raised his ears.

He lived well in Chang'an City, went to school, memorized books and practiced every day, and lived well and did not want to join the army at all.

Even if it was requisitioned, he just wanted to travel with the aristocratic families of the Imperial Academy.

It is a security guarantee group and a group that can make money and make money, which can make many people gilt.

Li Hongru has been preparing to learn a lot and wait until the right time to get some extra money.

But Xu Maogong disrupted this plan.

Wang Fuchou was a little unbearable at this time.

The first level of official position is to kill people, let alone a general like Xu Maogong who is close to the king.

The other party has the military power of a state, not an honorary position, but a real powerful general.

"He is still young, so I'm afraid he can't stand this kind of tossing."

"The young birds have become eagles after storms. How can Dr. Wang become a great man by promoting growth in the greenhouse?"

"I lost a student in the wind and rain. It's not been two months since I bought this one."

"That's the person you left and followed is wrong. If you follow me, he wouldn't be surprised. It's not that I, Old Xu, bragging. There are only a few people who can beat me. No one I want to protect can kill."

...

"It must be made willing to do this himself."

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

Wang Fuchou was finally unable to resist the promise that Xu Maogong had slapped his chest.

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

First rituals and then troops.

When Xu Maogong came into contact with Li Hongru, Li Hongru was very clear about the other party's methods.

It comes slowly, making people unable to refuse.

After persuading Wang Fuchou, it became an easy task to convince Li Hongru and the Li family.

"pill!"

Li Hongru sighed inwardly.

The leisurely little day is about to end.

A telescope gave him the opportunity, and at this time it also brought some bad consequences.

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

He drew a schematic diagram of the telescope and made many explanations, just to be ignored.

But Xu Maogong seemed to have other thoughts.

He either didn't want to leak the secret, or was on guard against some people, or was in a hurry to make mistakes, so Xu Maogong did not find anyone else to replace him.

Take things and people away together, which will limit the knowledge of the telescope to a very small range.

Without leaks, there will be a chance to strike against the enemy.

Li Hongru recalled it in his head.

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

"My friend Li Hongru, are you interested in going to our Bingzhou for fun?"

Xu Maogong's eyes were smiling, but it was like a strange millet that seduced Loli, and his eyes were filled with the meaning of having to play.

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

Li Hongru sighed.

He has a backer at least, so he can't do voluntary labor.

Since he could not refuse, Li Hongru still wanted to get some due treatment.

"Do you know everything?" Wang Fuchou said strangely.

"Your communication is a bit loud, and you can hear it clearly in the inner room."

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

Until this moment, Wang Fuchou finally felt that he could give Xu Maogong some difficult problems.

Since he is such an important student, he must have important treatment.

If he was given up casually, he would be dismissed directly, and he would not blame him for writing poems to Xu Maogong and giving the other party a reputation of "beauty".

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

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

"How much can your parents and children get?"

Xu Maogong's words were a bit exaggerated.

After suffering from 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 as your son".

If this is the case, there will be more people who treat Xu Maogong as a parent-child, and he is not the only one.

"Governor Xu, you should give me a correct number. After all, my student family is ugly and realistic. I have to feed some food to facilitate work."

Wang Fuchou laughed and scolded, but the implication was that, and he needed an exact number.

"The literati hate the most!"

Xu Maogong looked at Li Hongru and finally muttered, starting to mention treatment, and bargaining.
Chapter completed!
