After Ning Yuan returned to his small courtyard, but after a while, the chief butler Ning Fu walked in and said to Ning Yuan respectfully: "Childe, Tianyinlou sent a box, saying that it was to be handed over to Gongzi. ”

"Huh?" Hearing this, Ning Yuan was stunned, and then he remembered the Qianjun Iron that Su Duwan Wanqing gave him, because of the Jin Family Firm, he didn't take it with him when he left Tianyin Tower, but he didn't expect Su Duwan Wanqing to send it to him.

Thinking of this Qianjun Tie, Ning Yuan also had a trace of expectation in his heart, and said, "Take it in." ”

"Yes!" Ning Fu nodded in response, then left the small courtyard, and after a while, he led someone to carry in the jade box made of Qiankun jade.

After waving off Ning Fu and the others, Ning Yuan stepped forward and opened the jade box, which was the cold Qianjun iron, a total of twenty pieces, each piece weighed a thousand catties, and the twenty pieces added up, that was a full twenty thousand catties.

Martial arts practice, through the martial arts, after the completion of the foundation, can open up the dantian, so as to cultivate the internal qi, the internal qi into the truth, the true qi into Gang, Gang into the congenital, this is the vast majority of martial arts martial arts cultivation road, so it is called internal cultivation.

In addition to this internal cultivation, there is also a cultivation method like Ruo Ningyuan that continuously strengthens the physical body through the cultivation of the Swallowing Yuan Catalogue, which can be called external cultivation.

However, external cultivation is often not pure, because except for special circumstances like Ning Yuan, no one will only focus on refining the physical body, the martial arts, the true qi in the dantian in the body is the real foundation, without the true qi, it is impossible to transform into gang, how to break through the limit of the human body, the threshold of life and death, and step into the innate nature?

If you don't enter the innate, it is impossible to get on the stage after all, so the method of external cultivation is mostly regarded as a side door, and even the miraculous skills such as the Swallowing Yuan Catalogue have not been widely spread.

One of the reasons is that in addition to the difficulty of the method of external cultivation to enter the innate nature, there is another reason, that is, although the method of external cultivation has made rapid progress in the early stage, it is full of obstacles in the later stage.

It's like this Swallowing Yuan Catalog, with Ning Yuan's qualifications, he can cultivate it to the third level in just one month, which is equivalent to the seventh-rank realm of an ordinary martial artist, and this kind of speed can't be compared to Ji Wushuang at the beginning.

But after reaching the seventh layer of Qi training, Ning Yuan's cultivation speed slowed down significantly, if it weren't for the Demon Clan's secret realm, Ge Yue used countless precious fruit elixirs to melt into a pool of water for him to absorb, so that Ning Yuan had enough accumulation, it would be impossible for him to cultivate the battle body totem and step into the realm of the fourth layer of the Swallowing Yuan Catalog.

And now that Ning Yuan had cultivated the Battle Body Totem with his own Chi You's blood, and after stepping into the fourth layer of the Swallowing Yuan Catalog, his physical body had already reached the limit that the human body could reach.

Even the great master of that one-grade realm, the physical body that was tempered day and night with Gang Qi was difficult to compare with Ning Yuan.

Such a strong physical body, although Ning Yuan has incomparably strong combat power, is also a shackle, a shackle that is difficult to break through.

The current Ning Yuan, even if he continued to eat the flesh and blood of the demon beast and absorb the essence of qi and blood to cultivate the Swallowing Yuan Catalogue, his entry into the realm was extremely slow, and he might not be able to go further for more than ten years, or even for life.

This is the disadvantage of the Swallowing Yuan Catalogue, a cultivation path with no way forward, if he continues to cultivate this Swallowing Yuan Catalogue, Ning Yuan will at most reach a point comparable to a first-grade great grandmaster, and it is impossible to be comparable to the Innate Realm.

On the other hand, the path of internal cultivation, although the early stage of entry is slow, but it is laying the foundation, as long as the perfect foundation is laid, there is a road to heaven behind it.

So don't look at Ning Yuan's physical strength now, even ordinary grandmasters are not his opponents, but this situation is only limited to the Nine Rank realm.

Internal cultivators, as long as they break through the threshold of life and death in their bodies and step into the innate realm, they will be able to refine their physical bodies with their innate qi, and when the time comes, even if Ning Yuan cultivates the Swallowing Yuan Catalogue to the extreme, it will not be able to compare.

The innate realm has already transcended the limits of the human body and stepped into a higher level of life, so in the eyes of ordinary people, the innate strong person is a god-like existence.

This is the difference between internal cultivation and external cultivation, one has unlimited potential, and the other has been shackled from the beginning.

Even Ning Yuan, now he has to face this problem, the ordinary demon beast flesh and blood has no effect on his cultivation, it can help him break through, only the flesh and blood that exists supreme among those demon beasts, such as the true dragon and the phoenix, but this kind of thing can be thought of, it is an existence that even the innate powerhouse does not dare to provoke.

And in addition to the flesh and blood of demon beasts, there is another way, that is, with the help of external forces, some supreme treasures can also help Ning Yuan break through, such as the current Qianjun Tie.

This is the essence of the dark iron produced in the abyss of the southern region, each piece has a weight of thousands of catties, which contains the essence of the dark iron, which can continuously quench the flesh and blood, plus the weight of this thousand iron, it can also play a role in exercising the body.

Therefore, this Qianjun iron is also the best material for casting and or armor, a piece of Qianjun iron, worth 100,000 gold, is still priceless, Su Duwan Wanqing gave Ning Yuan a full twenty pieces of Qianjun iron as soon as he made a move.

Regardless of whether this matter is sincere or sincere, it is not false or wrongful, but for Ning Yuan, who has already reached the limit of his human body, this Qianjun Iron is of great significance, although it cannot allow him to step into the innate realm, but it can allow him to cultivate the Swallowing Yuan Catalogue to the seventh layer, that is, the realm of the grandmaster.

At that time, even if you can't defeat the innate nature, but at least you have a trace of self-preservation, if you add the hero card, you may not be able to fight with it.

Thinking of this, Ning Yuan no longer hesitated and took out Qianjun Iron from the jade box.

In this jade box, in addition to the twenty pieces of Qianjun iron, there are two pairs of bracers that are also made of Qianjun iron, which are used to place Qianjun iron, after all, this Qianjun iron is too heavy, and ordinary bracers can't bear the weight of this Qianjun iron at all.

Bringing the two pairs of wrist guards to the wrists and ankles respectively, Ning Yuan obviously felt the heaviness of this thousand irons.

It is a martial artist who cultivates internally, and after reaching the realm of the six grades, the physical body also has the ability to load thousands of catties, and if you use true qi, you can even reach a load of ten thousand catties.

And Ning Yuan's physical body has already reached the limit of the human body, and the load can be nearly 100,000 jin of strength, although this load does not mean an explosion, but this kind of power is also terrifying to the extreme, even the incomparably heavy blood gentian in his hands can also be like a spirit snake.

And after bringing these two pairs of bracers, Ning Yuan could clearly feel the heaviness, which was enough to explain the weight of Qianjun Tie.

In addition to the heaviness, there was also a trace of cold and sharp Xuantie essence gushing out from Qianjun Iron, constantly piercing into Ning Yuan's body, beginning to stimulate Ning Yuan's flesh qi and blood, strengthening his physique, although this process was extremely slow, but if it was accumulated over time, it would definitely be a gain that could not be underestimated.

Of course, this process must not be very pleasant, the dark iron essence shuttling through the body, it is like thousands of long needles piercing the body, and the pain spreading among the limbs and hundreds of bones is enough to make ordinary people collapse.

Therefore, the method of external cultivation is even more difficult in the future.

But fortunately, Ning Yuan didn't have any other strengths, that is, his endurance was particularly strong, coupled with the influence of Chi You's blood, this pain was quickly adapted to him, and he began to put Qianjun Iron into the bracer.

Twenty pieces of iron, five pieces of each wrist guard, plus the weight of the wrist guard, is almost 25,000 catties.

With such a weight on his body, Ning Yuan also felt a little heavy, and coupled with the enhancement of the dark iron essence, the pain connected to the refining body was even more intense.

This made Ning Yuan smile bitterly and muttered, "Isn't this cultivation method fatal?"

Having said that, Ning Yuan didn't mean to solve this thousand irons, but instead picked up the blood gentian on the side, ready to practice marksmanship.

As a result, he didn't think about it, he stepped out of one step, and directly stepped out of a deep pit on the ground.

This is a manifestation of not being able to control his own strength, after all, he suddenly has an extra weight of 25,000 catties, and he will definitely not be able to adapt to it for a while, and it is okay to step out of a pit, if he does it on the stone bench on the side, he may directly crush this stone bench.

Although Qianjun Iron was extremely heavy, fortunately, Ning Yuan had reached the realm of lifting weights as lightly and lightly as weights, and he quickly adapted to this sudden increase in strength, stepping on the ground without crushing the ground, and even the footprints were very shallow.

Adapting to this power, Ning Yuan took the blood gentian and prepared to practice marksmanship.

At this moment, another sound of footsteps sounded, and the chief housekeeper Ning Fu walked quickly into the small courtyard and said to Ning Yuan: "Son, the chief steward of the Jin family firm asks to see him. ”

"Chief Steward Li?" Hearing this, Ning Yuan frowned slightly and asked, "Is he the only one?"

Ning Fu nodded and said, "Yes, he looked in a hurry, as if he was in a hurry to see you." ”

Hearing this, Ning Yuan put down the blood gentian and said, "Please let him in." ”

"Yes!" Ning Fu left in response, and soon walked into the courtyard with a person, it was the big steward Li with a hurried expression, and he was still holding a small box in his hand.

Seeing Ning Yuan, Steward Li hurriedly stepped forward, and then knelt directly on the ground, and said excitedly: "Yuan Shao, please save the young master!"

"Huh?" Hearing this, Ning Yuan's eyes froze, he glanced at Chief Steward Li who was kneeling on the ground, and then said to Ning Fu: "You go down first." ”

"Yes. Although Ning Fu saw that this matter was unusual, Ning Yuan spoke, and he didn't dare to ask anything, so he turned around and left.

Only Ning Yuan and the chief steward Li who knelt on the ground were left in the courtyard, Ning Yuan sat down and said, "Okay, stand up, tell me what the hell is going on with first?"
