Lao Zhang handed the wrapped black iron knife to Su Yu. Su Yu weighed the weight of the black iron knife and found that it was just right for him, so he took out the black iron knife.

The blade body, which is as deep as the night, has shallow lines, which are like human meridians, giving life to the black iron blade.

Holding it in his hand, Su Yu felt as if he had met an old friend for many years, with a familiar yet unfamiliar feeling.

With a slight stroke, the invisible sword energy sliced ​​through silently.

The size and weight were just right. Su Yu nodded with satisfaction, stroked the black iron sword and said, "I'm very satisfied, Lao Zhang. I feel that your forging skills have improved a lot. I will still forge swords from you in the future."

.”

Lao Zhang was naturally happy and said with a smile: "It would be better if we get more rare ores."

"This is the remaining purple gold ore, returned to you."

Su Yu took the purple gold ore, said goodbye to Lao Zhang, and returned to the yard at home to get used to the weight of the black iron knife and test the sharpness of the black iron knife.

He gently threw a piece of purple gold ore away, held the handle of the knife lightly with his right hand, and chopped it lightly, cutting the purple gold ore into two halves like cutting tofu.

Yes, it's very sharp. Even if it's armor made of purple gold ore, I can easily cut through it.

Upgrading the black iron sword with purple gold ore is also to deal with the situation when the enemy is wearing armor. Now, the black iron sword fused with purple gold ore is sharp enough. Even if the enemy is wearing armor, Su Yu can easily deal with it.

"Huh, we have a transaction tomorrow. Let's focus on practicing today and no longer make alchemy."

In the remaining time, Su Yu focused his energy on practicing the Golden Silkworm Kung Fu, hoping to break through it to the next level.

After practicing all afternoon, Su Yu was exhausted and aching all over. A large amount of sweat came out of his forehead and dripped down. The floor was covered with Su Yu's sweat.

Su Yu took a bite of the Rejuvenation Pill and had a premonition that his Golden Silkworm Kung Fu was about to break through, so he started to perform the Golden Silkworm Kung Fu movements.

In conjunction with each of the weird movements, the bones and joints in Su Yu's body seemed to be opened and became flexible. Movements that were originally very difficult to perform became soft and smooth.

The vitality of the body was also affected, growing and strengthening, becoming more solid, and even taking on a hint of green color.

Click, click, like a chain being broken.

Su Yu's body was also sublimated, pieces of skin fell off, and the already white skin became even whiter and more shiny, like a newborn baby.

The skin is no longer stiff, but has elasticity, and is as silky as water.

Su Yu took a long breath.

"The Golden Silkworm Skill finally broke through!" Su Yu stopped his movements and opened the attribute panel.

Name: Su Yu

Lifespan:89

Potential: 13

Martial arts: Health-preserving boxing (51% of the results are gained from the heart), basic sword skills (88% of the gains are gained from the mind), drawing sword skills (30% of the gains are gained from the mind), Golden Silkworm Kung Fu (1% of the gains are gained from the mind), Extreme Thunder Body Technique

(25% achieve something small)

Skills: Pharmacy (99% of what you gain), Alchemy (90% of what you gain)

At this time, all martial arts and skills have risen to the level of what one can achieve.

"Experiment with the Golden Silkworm Skill after the breakthrough."

Su Yu took out the black iron sword, hesitated for a moment, then slashed at the arm, using three-thirds of his strength.

Like being hit by soft cotton, the skin rebounded most of the force. Not only did it not suffer any damage, it didn't even feel painful, it was just slightly itchy.

Su Yu's eyes lit up, astonished by the powerful defensive power of the Golden Silkworm Kung Fu.

Try harder and try again!

This time, Su Yu used 70% of his strength, which was equivalent to 400 kilograms of force plus the sharpness of the black iron knife, to hit himself.

The skin rebounded most of the force again, but it was still injured, and red blood flowed out along a thin line.

"As expected..." Su Yu thought of the incident in his previous life when he smashed his cell phone in a desperate attempt to kill himself.

Although the defense of the Golden Silkworm Skill is high, it is not an absolute defense. If I use my full strength, this arm will be cut off.

However, even so, Su Yu was very satisfied. He was able to withstand an attack with a force of four hundred kilograms. This defensive power was already astonishing.

He believes that if he practices the Golden Silkworm Skill for a while, his body will be comparable to a treasure armor and he will not need additional armor to protect himself.

After practicing all afternoon, Su Yu's body was very tired, and a warrior could not practice for a long time. In addition, he had to trade tomorrow, so Su Yu stopped practicing and lay down on the bed early and fell asleep.

The next day, Su Yu put on the mask he wore last time in the ghost market, prepared the rejuvenation pills, used the Extreme Thunder Body Technique, and rushed to Yushui Creek.

The man didn't tell me the time, and I didn't know if he was near Yushui Creek.

Su Yu soon arrived near Yushui Creek and found the man also wearing a mask, with three extraordinary and powerful warriors behind him.

Su Yu felt a strong sense of crisis among these three warriors.

Their strength is extraordinary, and they are probably all Qi Yun realm warriors... The situation is not right, so run away immediately.

However, it stands to reason that there is no need for them to hurt themselves. After all, there is still a cooperative relationship between the two.

"Here are one hundred and sixty rejuvenation pills, please count them." Su Yu took out the pills and put them on the ground.

The man with the red face mask counted the quantity and the quality of the elixir, stood up, nodded slightly and said: "Yes, your alchemy talent is the best I have ever seen."

In a short period of time, the quality of the elixirs has improved a lot, and being able to refine so many high-quality rejuvenation elixirs in such a short period of time is enough to prove that the talent is extraordinary.

"Where's the money?" Su Yu came here to trade mainly for the money.

"Here you go, seven hundred taels of silver notes. No need to look for them." The red-faced masked man handed the seven silver notes to Su Yu.

Su Yu took it cautiously and asked by the way: "I want to ask if you have any blood training methods to strengthen your qi and blood."

"Except for elixirs and learning martial arts."

The red-faced mask smiled coldly: "If you want to ask for information from me, why not... join us and become one of us, then I will tell you."

Hearing this, Su Yu's eyes turned cold and he ran away.

The opponents were four Yun Qi realm warriors, and Su Yu was not confident in dealing with four Yun Qi realm warriors.

"Wait a minute...young man, we are actually good people."

Su Yu snorted silently in his heart. He didn't believe the lies of the red-faced masked man at all. He silently moved his hand to the handle of the knife and silently used the Thunder Breathing Technique.

"I really have a blood training method that uses the blood of monsters to strengthen my own blood. If you are interested, just give me three hundred taels of silver."

Seeing that Su Yu was about to run away, the red-faced masked man said anxiously.

"Here, three silver notes." Su Yu remained vigilant, kept a safe distance, and threw the bank notes to the red-faced man.

"Hey. Here, this is a blood training method I got. It needs to be matched with the bloodline of the Demon King."

Su Yu took over a piece of yellow parchment, frowned and said, "Bloodline of the Demon King?"

"The existence that is superior to monsters and beasts is called a monster king, which is equivalent to an innate warrior."

When Su Yu heard this, he almost cursed. Isn't this a trick on him? If a demon beast with innate warrior level strength is allowed to obtain the blood of the demon king, isn't this asking for death?

"Young man, calm down, I didn't trick you." The red-faced masked man continued: "We found an injured demon king, whose strength has dropped to the level of a demon beast. We need you to cooperate with us to obtain the blood of the demon king."

"I'm not strong enough, so I'll take my leave."

If he falls to the level of a monster, just let them deal with it. Su Yu doesn't want to take such a big risk.

The voice of the red-faced mask turned cold: "Young man, don't deny me face. It's not good to be too young and energetic."

Su Yu ignored him and immediately left the scene with his extremely thunderous movement technique, hiding in the woods like lightning.

"What a speed!" A person behind the red-faced masked man said in surprise, but he didn't look like he was in a hurry to chase after him.

"Boy, do you think you can escape from my grasp?" the red-faced masked man said coldly.

At this moment, Su Yu had already run for ten miles. Looking behind him, he secretly breathed a sigh of relief and said, "I should be able to get rid of them now."

Su Yu was stunned and felt something was wrong. Why didn't he come after him?

Is it possible that there is a way to track myself?!

As soon as Su Yu thought of this, he saw four figures rushing towards him quickly. One of them shouted in a voice like an oven: "Boy, don't run away, you can't run away from us."

"There is really a way to track me!" Su Yu couldn't figure out how he tracked himself, and when he tampered with him.

Is it possible that they have known about my stay in Stone Village for a long time? No, there must be distance restrictions, there can be no distance restrictions!

Su Yu's thoughts flashed quickly, and he used the Extreme Thunder Movement Technique again and ran wildly.

"Damn, why is this kid faster than us!"

"Hong Gong, don't scare him, catch up with him and explain clearly!" The man in the red face mask was a little panicked at this time.

If such an important alchemist is lost, he will definitely be severely punished!

"Damn it, this kid is so good at running away!"

The red-faced masked man never expected that Su Yu could be so fast and maintain such a long time.

Su Yu's body movement was very fast, passing through trees and streams, and he ran for twenty miles close to the limit of his body.

"Huh...huh, I don't believe they can catch up."
To be continued...
