A little surprise flowed from Su Heng's face.

His current physical strength, three blood refining superimposed copper skin and iron bone talent, ordinary swords are difficult to pierce the flesh and skin.

But the thin old man in front of him.

Just by simply using two fingers, he almost made Su Heng break his defense.

"It is worthy of being a martial artist..."Su Heng said secretly in his heart: "It is really extraordinary." ”

"How old are you?"

"Fifteen." Su Heng replied with a serious face.

Hearing this, the thin old man's palm that was stroking his long beard violently slammed into a force, almost pulling off a gray beard directly.

Senior brother Lu Ping, who was standing beside the old man, also showed a surprised expression on his face for the first time, as if he had re-acquainted himself with Su Heng, and looked up and down seriously.

"You... Fifteen years old? ”

The old man looked two meters tall and full of muscles.

Standing in front of him relaxed, the shadow was enough to completely envelop Su Heng, his face was full of astonishment.

Su Heng thought about it for himself, nodded seriously, and repeated: "That's right!" ”

"At the age of fifteen, three blood refining successes... Boy, you're so talented. ”

After a long time, the old man slowly accepted the matter. He lay on the recliner and took a chicken foot from the table next to him, his face full of emotion.

Just didn't wait for Su Heng to be happy.

The old man's words turned sharply, shook his head and sighed: "It's just, it's a pity... Your martial arts are too miscellaneous. ”

"Too miscellaneous?"

Su Heng looked at the old man in front of him with some confusion.

"You should know that the human body is like a big water tank, and the water capacity in the tank is limited. This water is the qi and blood in our body. ”

The old man explained with a serious expression, but Su Heng turned sideways slightly, not letting go of every word that the old man said:

"And refining blood is equivalent to the process of changing the water in the water tank.

Through cultivating day and night, the qi and blood in your body will gradually transform into a special and powerful seal blood.

Each kind of blood refining martial arts, the blood that is transformed is different. But the difference is that some of the seals can cooperate with each other and promote each other. Other blood seals may contradict each other and conflict. ”

"It is conceivable that it is also the third blood refining consummation. Others practice a complete set of exercises, and the blood seals cooperate with each other, and the power of the twelve points is exerted with one punch. And your exercises are too chaotic and complicated, and a punch can only exert seventy percent or even less than seventy percent of the power, and in the case of life and death fighting, of course, the former has a greater chance of winning. ”

After hearing such an explanation.

Su Heng's complexion gradually became a little solemn.

However, that's not all. The old man raised his hand, and Lu Ping, who was beside him, brought a cup of tea with a very eye-catching eye.

After drinking all the tea in the cup and coughing twice, the old man continued to speak: "The gap in combat power alone is secondary. What's more, if you want to impact the realm of refining martial artists in the future, the blood seals and blood conflicts with each other and cannot be condensed, and it is difficult to successfully break through the level. ”

"I see."

Su Heng asked, "So, is there a way to disperse the exercises you practiced?" ”

"Yes, but it's difficult." The old man stretched out his hands: "The specific method, it's not that I don't want to tell you, but even I don't know." If you go to the state capital in the future and see a bigger world, you may find a way. ”

Su Heng still didn't give up, and continued to ask:

"Then can I continue to practice the mutual set of blood refining martial arts, and refine more blood in my body?"

"Such hope is not impossible..."

The old man thought about it seriously and explained, "But have you ever thought that the more times you refine blood, the more difficult it will become. ”

Su Heng's face was a little dazed.

What the old man said seemed to have some truth, but Su Heng's cultivation had never encountered any bottlenecks so far, and he didn't have much feeling in this regard.

However, the people around him all nodded slightly, obviously agreeing with what the old man said. Martial arts practice is like climbing a peak, the higher you go, the more difficult it becomes.

"Get back to practice for me!"

The old man scolded angrily, and the disciples who had quietly gathered around dispersed one after another.

"These unsuccessful guys!" After scolding in a low voice, the old man shook his head slightly and continued to talk about the topic just now: "Do you know why this is? ”

Su Heng has not yet answered.

The old man continued to explain, "This is because, whether it is a blood refining martial artist, a refining martial artist, or even a more powerful martial arts master... The amount of qi and blood in our body is limited. ”

"Your first time refining blood, you have enough qi and blood, so it is naturally much simpler.

But when you refine blood for the third time, a large amount of qi and blood has already been transformed into seal blood, and the remaining qi and blood are thin, and it will naturally become extremely difficult to succeed in blood refining.

So, theoretically speaking, a martial artist can perform a fourth or even more blood refining, but that kind of situation is too rare, I have never seen it in more than 30 years, and I have never heard of it. ”

The old man paused slightly, and then continued:

"As for things like qi and blood, they are destined by nature, and they have nothing to do with cultivation.

Generally speaking, the taller the body and the more nutritious the person, the more qi and blood will be more abundant than the person who is thinner.

If you compare the human body to a big tank, it's easy to understand.

However, such a gap is not too exaggerated.

You can have a height of two meters or nearly two meters, and the blood of the innate weather has surpassed ordinary people by a lot.

But you can't grow your height indefinitely, you can't grow to two or five or three meters, because everyone has their own limits, and it's fate. ”

Speaking of which.

The old man seemed to have thought of something, shaking his head slightly, and his old face was full of memories and sighs.

Hearing these words, Su Heng was really relieved in his heart.

The old man was right, humans do have their own limits.

But Su Heng's situation is slightly different, with the help of the immortal talent, Su Heng's body size can grow unlimitedly, theoretically speaking, Su Heng's qi and blood are unlimited.

He can practice the Dharma as much as he wants.

And now, the problem of messy exercises may bring a little trouble to Su Heng.

But with the growth of Su Heng's body and qi and blood in the future, and the increase of martial arts cultivation, these troubles will eventually be transformed into a part of his strength.

However, as long as you know these things, there is no need to explain them to outsiders.

Thinking of this, Su Heng's eyes suddenly felt brighter, and a feeling of refreshment arose.

"The path of martial arts is like climbing a mountain, if you don't advance, you will retreat. In any case, I can't give up easily. Su Heng clasped his fists at the old man and said, "In the future, I will ask the master to take care of him." ”

The expression on the old man's face was stunned for a moment.

Seeing that Su Heng's face was full of open-mindedness, not half gloomy, he was surprised.

The old man drank all the tea in the cup, then shook his head and smiled: "Boy, your heart to the Tao is extraordinary, and you may really be able to achieve something great in the future, wonderful!" ”
