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

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

Holding it in his hand, Su Yu seemed to have seen an old friend for many years, and he had a familiar but unfamiliar feeling.

With a slight swipe, the invisible sword qi slashed silently.

The size and weight are so just right, Su Yu nodded with satisfaction, stroked the black iron knife, and said: "I am very satisfied, Lao Zhang, I feel that your forging skills have improved a lot, and I will look for you to forge a sword in the future." ”

Lao Zhang was naturally happy and smiled: "It would be better if there were more rare ores." ”

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

Su Yu took the purple gold ore, said goodbye to Lao Zhang, returned to the courtyard of his home, got used to the weight of the black iron knife, and experimented with the sharpness of the black iron knife by the way.

Gently toss a piece of purple gold ore away, gently holds the handle of the knife in his right hand, and gently slashes it, cutting the purple gold ore like cutting tofu, cutting it in half.

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

Upgrading the Black Iron Knife with Purple Gold Ore was also to deal with the situation where the enemy was wearing armor, and now, the sharpness of the Black Iron Knife that had melted the Purple Gold Ore was enough, even if the enemy was wearing armor, Su Yu could easily deal with it.

"Huh, I'm going to trade tomorrow, concentrate on cultivation today, and no longer alchemy."

For the rest of the time, Su Yu focused his energy on practicing the Golden Silkworm Gong, wanting to break through to the next level.

After an afternoon of cultivation, Su Yu was exhausted, his whole body ached, sweat the size of a bean was dripping down his forehead, and 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 Gong was about to break through, and then he started the action of the Golden Silkworm Gong.

With the strange movements, the bones and joints of Su Yu's body seemed to be opened, and they became flexible, and the movements that were originally very difficult to do became soft and smooth.

The vitality of the body was also affected, and it grew and strengthened further, becoming more condensed, and even had a hint of green.

Click, click, like a chain has been broken.

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

The skin is no longer hard, it is elastic and silky like water.

Su Yu exhaled.

"The Golden Silkworm Gong has finally broken through!" Su Yu put away his actions and opened the properties panel.

Name: Su Yu

Lifespan: 89

Potential: 13

Martial Arts: Health Boxing (51% Heart), Basic Knife Technique (88% Heart), Knife Drawing (30% Heart), Golden Silkworm Gong (1% Heart), Extreme Thunder Body Method (25% Small Success)

Skills: Pharmacy (99% Heart), Alchemy (90% Heart)

At this moment, all martial arts and skills have risen to the level of gain.

"Let's experiment with the breakthrough Golden Silkworm Gong."

Su Yu took out the black iron knife, hesitated slightly, slashed at his arm, and used three points of strength.

As if on soft cotton, the skin bounced back most of its strength, not only did it not suffer a trace of damage, but it didn't even feel pain, just a slight itch.

Su Yu's eyes lit up, and he was surprised by the strong defensive power of the Golden Silkworm Gong.

Try harder!

This time, Su Yu used seven points of strength, equivalent to four hundred catties of strength plus the sharpness of the black iron knife to hit him.

The skin rebounded most of its strength again, but it was still damaged, and red blood flowed down a thin line.

"Sure enough, I can't prevent ...... cheap," Su Yu remembered that he had smashed his mobile phone in his previous life.

Although the defense of the Golden Silkworm Gong is high, it is not an absolute defense, if you use all your strength, this arm will be cut off.

However, even so, Su Yu was very satisfied, and he was able to resist the attack of four hundred catties, which was already amazing.

He believed that if he cultivated his Golden Silkworm Gong for a period of time, his body would be comparable to treasure armor, and he would not need additional armor to protect himself.

After an afternoon of cultivation, Su Yu's body was also very tired, and the martial artist couldn't go to practice for a long time, plus he had to trade tomorrow, so Su Yu didn't continue to cultivate, and fell asleep on the bed early.

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

The man didn't tell me the time, and I don't know if I got to the vicinity of Yushui Creek.

Su Yu soon came to the vicinity of Yushui Creek and found that the man who was also wearing a mask had three powerful warriors behind him.

In these three martial artists, Su Yu felt a strong sense of crisis.

The strength is extraordinary, I'm afraid they are all Qi Realm martial artists...... If the situation is not right, 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.

"This is one hundred and sixty rejuvenation pills, you count them." Su Yu took out the pill and put it on the ground.

The man with the red-faced mask counted the quantity, as well as the quality of the pill, got up, nodded slightly, and said, "Yes, your alchemy talent is the best I have ever seen." ”

In such a short period of time, the quality of the pill has improved a lot, and the fact that so many high-quality rejuvenation pills can be refined in such a short period of time is enough to prove that the talent is extraordinary.

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

"Here you go, seven hundred taels of silver tickets, don't look for it." The red-faced masked man handed seven silver tickets to Su Yu.

Su Yu cautiously took it and asked by the way: "I want to ask, do you have a blood training method to strengthen qi and blood." ”

"Except for pills and learning martial arts."

The red-faced mask smiled coldly: "If you want to ask for information from me, why don't you ...... Join us and be one of us, and so, I'll tell you about it. ”

Hearing this, Su Yu's eyes were cold, and he was about to run away.

The other party was four Qi Realm martial artists, and Su Yu didn't have the confidence to deal with the four Qi Realm martial artists.

"Wait a minute...... Young people, we are actually good people. ”

Su Yu snorted silently in his heart, he didn't believe the red-faced masked man's nonsense at all, and silently moved to the hilt of the knife with one hand, silently casting the Extreme Thunder Breathing Method.

"I really have a way to practice blood, use the blood of demon beasts to strengthen my own qi and 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 a little anxiously.

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

"Huh. Here, this is a blood practice method I got, and it needs to cooperate with the demon king's bloodline. ”

Su Yu took a piece of yellow parchment, frowned, and said, "Demon King bloodline? ”

"The existence above the demon beast is called the demon king, which is equivalent to an innate martial artist."

When Su Yu heard this, he almost didn't scold, isn't this a pit for him, a demon beast with innate martial artist-level strength, let him obtain the blood of the demon king, isn't this looking for death?

"Young man, calm down, I didn't cheat you." The red-faced masked man continued, "We have found an injured demon king, whose strength has fallen to the level of a demon beast, and we need you to cooperate with us to obtain the blood of the demon king together. ”

"I'm not strong, so I'm leaving."

Falling to the level of a demon beast, then just let them deal with it, Su Yu didn't want to take such a big risk.

The red-faced mask's voice cooled down: "Young man, don't lose face, it's not good to be too young and vigorous." ”

Su Yu ignored him, and directly burst out of the Extreme Thunder Body Technique and left the scene, hiding in the woods like lightning.

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

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

At this moment, Su Yu had already run ten miles, looked behind him, and secretly breathed a sigh of relief: "This time it should be to get rid of them." ”

Su Yuyou was stunned and felt that something was wrong, why, didn't he chase himself?

Could it be that there are means to track yourself?!

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

"There's a way to track me!" Su Yu couldn't figure out how he tracked himself, and when he did something to him.

Could it be that they already knew about me in Stone Village? No, there must be a distance limit, and it is impossible to have no distance limit!

Su Yu's thoughts flashed quickly, and he once again used the Extreme Thunder Body Technique to run wildly.

"Rub, how can this kid be faster than us!"

"Hong Gong, don't scare him, hurry up and catch up with him and explain clearly!" The red-faced masked man was a little panicked at this point.

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

"Damn, this kid is too good to run!"

The red-faced masked man had never expected that Su Yu's speed would be so fast and that he could maintain it for such a long time.

Su Yu's body method passed through trees and streams extremely quickly, and ran for twenty miles close to the limit of his body.

"Whew...... Phew, I don't believe they can catch up. ”

Su Yu jumped onto a stream, washed his clothes, and washed his body, he guessed that it was because the other party had a certain fragrance on his body or clothes, which could be tracked by special means.

However, Su Yu, who had just washed his body and put on his clothes, saw the red-faced masked man again, and the expression on his face suddenly froze.

"Do you have to catch me and let me go?" Su Yu was about to perform the Extreme Thunder Body Technique when he was about to run again.

Suddenly, a white arrow came at a rapid speed in front of him, and the speed was extremely fast, and he didn't have time to use the Extreme Thunder Body Technique, so he could only dodge in a hurry.

"Boy! It's easy for me to find, don't run away, we're really good people. ”

As soon as Su Yu dodged, he felt that his shoulder was pressed, and the voice of a strong man came from behind.

He lowered his head helplessly, knowing that he had no way to escape, and the other party didn't seem to have such great malice, the strong man behind him had already caught him, and he could completely remove his arm and teach himself a lesson.

However, the other party did not do this, but could clearly feel that the other party was deliberately restraining his strength, as if he did not want to hurt himself.

At this time, the red-faced masked man walked over and sighed: "You kid, obviously you are just a martial artist in the Inner Strength Realm, and you can run better than us...... Whew, no, let me hold off. ”

Su Yu looked up at the red-faced masked man and asked, "What do you want me to do?" ”

"Didn't you say it, cooperate, cooperate with us to find the bloodline of the demon king."

"Why do you fancy me, I'm just a little warrior in the inner realm."

"No, no, no, you're still an alchemist, that's the most important thing."

"After the demon beast of the killer demon king level, we need you to refine the pill with the demon king's heart, and I will give you the pill when the time comes, even if you give it to you now, you won't be able to practice."

"Therefore, I need a talented alchemist, who has a high alchemy success rate after reading the Dan recipe once, and also has a certain martial arts strength, otherwise it will be difficult to deal with the corrosion of demonic energy, and there are very few people who can meet these points, so we can only ask you for cooperation."

Su Yu knew that he had no choice, and said, "Let go of me first, I won't run, it makes me very uncomfortable to hold on to it like this." ”

"Liu Yang, let him go." The red-faced masked man said kindly.

Su Yu stretched his body and said, "When will I go, I have a good mental preparation." ”

"On the fifteenth day of the next month, when the demonic energy is at its peak, the demon king's heart obtained at the peak of the demonic qi is used to refine the pill, and it is the easiest to succeed."

"Can you tell me how you found out where I am?"

"That's not going to work, I told you, you kid didn't know where he had slipped away. This cooperation is also good for you, after the Demon King's bloodline refining and strengthening your blood, your martial arts realm will reach a new level. ”

"Okay, I'll work with you." Su Yu can only agree now.

Moreover, this matter is indeed beneficial to him, he can get the mysterious Dan Fang and obtain the blood of the demon king for blood training.

"Okay, in order to show our sincerity, this poison pill is given to you. However, we have the antidote to this poison, so don't think of using it against us. ”

They seem, really good guys?

Su Yu still cautiously took the poison pill prescription in his heart, there was no good thing for no reason, for this kind of thing, it was difficult for Su Yu not to be cautious.

"Okay, you can go, when it comes to the fourteenth, we will take the initiative to come to you, and see you then, I hope your strength can be improved to another level, at least don't become a laggard then."

After the red-faced masked man finished speaking, he took the rest of the people away, Su Yu looked at a blood practice method and a poison pill with some astonishment, and was vaguely uneasy.

Accept it first, as for whether there is a problem with the two things, you can wait until you verify.
