Just as the paper is corroded by sulfuric acid,

A small piece of long gold ingot in Li Ang's hand quickly melted and eroded, covering the sponge-like internal hollows, becoming riddled with holes.

On the surface of countless ink-colored silk threads, wisps of golden light appear, flowing to the part under the skin.

Li Ang could feel that the weight of his palm had not increased, nor did he feel severe pain.

At the same time, the ink-colored silk thread did not seem to be satisfied with absorbing a small piece of gold ingot. On the contrary, it continued to wind and stretch towards the other gold ingots in the wooden box as if it had smelled a metallic breath.

"Bang!"

Li Ang pulled back his palm, closed the wooden box heavily, and took a few steps back.

The oil lamps and candles on the table were swaying, reflecting his uncertain expression.

The ink-colored silk thread swayed in the air for a while, and then it "unwillingly" absorbed all the remaining gold nuggets and retracted under the skin.

“…”

Li Ang stared at his palms, with clear lines in the palms, long lifelines, and veins vaguely visible.

No wounds, no blood.

"It's not possible to solve it. You must figure out what the ink-colored silk thread is."

Li Ang took a deep breath, took the wooden box containing gold ingots and sat down in the living room, and once again combed out the passage of his ink-colored silk thread.

First of all, time.

At around 6 o'clock yesterday morning, he and Jiao Cheng and others got a stone box in the underground palace of Jianxian Clothing Tomb. Jiao Cheng opened the stone box and found the ink silk, causing the underground palace to collapse. Everyone fled to the corridor, and the rest, including Jiao Cheng, died. When Li Ang left, he touched the ink silk thread in the stone box and was parasitized by him.

‘Jiao Cheng was the first person to open the stone box, but the Mo Si did not parasitize him. There are two possibilities: one is that the conditions are inconsistent, and the other is that the contact method is incorrect.’

Li Ang said silently: "Jiao Cheng's age has exceeded the range suitable for practice. According to the classics of the Academy, his spiritual veins have long been closed and rigid - and my spiritual veins are still active.

This may be the difference.

And the second possibility is the way of contact.

Jiao Cheng just opened the stone box and did not touch the ink silk thread with his palm. I had direct contact with the ink silk with his palm.

Of course, there may be two reasons for both - direct contact and spiritual veins activated.’

Li Ang raised his right hand and pressed his fingers on the hot oil lamp glass cover in turn. He saw that the whole finger was red under the candlelight, and the venous artery patterns inside were clear.

‘You can barely see the ink silk. The single diameter is very thin. It is a branch-shaped branch, covering the whole finger.’

If an ordinary person saw his fingers covered with silk threads and thought of his body that might have been parasitized and devastated, he might have screamed in horror.

However, after all, Li Ang was a person who had pulled out the dragon worm with his own hands for ten hours in a row. There were countless parasitic lesions that were sour and curious in his mind. His first reaction was not to be shocked, but to try to understand and analyze.

‘There is no obvious problem with my physical function, and my hands and feet are moving normally.’

Li Angsi asked: ‘The information currently known is.

1. Ink silk can guide spiritual energy and connect spiritual veins.

2. Ink silk has a certain ability to move freely and is indestructible.

3. Ink silk usually lies dormant under the skin. When attracted by gold, it will directly pierce out of the body surface and absorb gold.

4. When the ink silk moves, it will not cause any wounds or bleed.’

First of all, when he just crawled out of the underground palace, Li Ang had already discovered that when he guided the spiritual energy into the spiritual vein, it was unobstructed and there was no painful reaction.

‘Before, I used sunken wood, fine gold and other materials to conduct spiritual vein connection experiments. Without holding any materials, I introduced spiritual energy into the spiritual vein, and the pain was 1.

When holding purple Dushan chalcedony, the pain is 1.3.

The gloomy wood in Youzhou 1.2.

The best performance is the pure metal, with the pain level when holding it is 5.0. After making a ring and putting it on the head, the pain level drops to 1.5.

The higher the pain reduction from grip to the head ring, the higher the efficiency of the material to conduct spiritual energy.

The pain of the ink silk is 0.7, which means that it greatly supplements the broken defects of the spiritual vein, allowing the originally hopeless skull breaking sword to practice.’

Li Ang pressed his eyebrows and thought, "The excellent conduction efficiency of the essence gold spiritual energy is already one of the most expensive special materials that can be bought in Chang'an Auction House.

Even the cultivator of the Yunxing Realm was so luxurious that he used a whole piece of pure gold to build a flying sword.

If the spiritual energy transmission efficiency of ink silk is higher than that of pure gold, it is very likely that it will be recorded in the Academy Library.’

Li Ang closed his eyes and silently recited the "Shangqing Inspiration Chapter". After a moment, he frowned slightly and opened his eyes.

I don’t know if it was an illusion, but after absorbing the gold ingot, he felt that the pain caused by driving the spiritual veins was slightly lower than before.

‘Can absorb metals enhance the spiritual energy transmission efficiency of ink silk?’

Li Ang thought in shock. After thinking for a while, he stood up, moved the box out of the corner of the wall, and took out all kinds of materials he had previously entrusted to the Duke of Yan's Mansion to buy from the Chang'an Auction House.

Including and not limited to wood, jade, metal, bones, etc.

Li Ang took a deep breath, put on the simple surgical gloves he made, took out all kinds of materials and arranged them neatly on the ground.

Then take off your gloves and take turns using your palm to test it out in the air.

Lantian jade, no response.

Gloomy wood, no response.

The crown dove feathers had no response.

The reaction was slightly strong. When the ink-colored silk thread was three centimeters away from the sterling silver, it pierced out of the skin surface and tried to swallow it.

Iron and copper, the reaction was extremely weak. The ink-colored silk thread did not appear actively after the palm touched the pure iron and pure copper. It was not until Li Ang used his spiritual energy that he barely tried to drill out of his skin.

Mercury, lead, and the reaction is weak.

Bismuth, the reaction level is close to that of silver.

Jin, strong reaction...

After some experiments, Li Ang finally confirmed that the ink-colored silk thread reacted relatively strongly to metals, especially gold and silver, and the "desire" to swallow was relatively high.

‘There is no experimental environment now, so metal elements such as oxalene, radium, uranium cannot be produced. Further experiments need to be carried out after the conditions are complete.’

Li Ang Si Sui said: "The next step is to explore whether the ink silk will further improve the efficiency of spiritual energy transmission after absorbing gold and silver metals."

He put all kinds of materials back into the box and put them in the box.

He put a few large pieces of silver ingots into the wooden box containing the gold ingots, came to the next room, took the wooden basin and fed water, poured a pot of clean water into the large wooden barrel for bathing until the barrel was filled with water.

Then Li Ang took off his clothes and lie carefully into the wooden barrel. He watched the water in the barrel overflow because of his volume. He opened the wooden box and slightly poked out of the water surface with his palms, and began to let the ink-colored silk thread absorb gold and silver materials.

When all the gold and silver in the wooden box were absorbed, the water in the wooden barrel did not overflow further.

"My volume has not increased at all..."
