"Very good! But in less than a day, you can understand the truth of this, which is very rare!"

Yang Dingtian glanced at Yun Zhan with satisfaction, nodded and said: "This sword-forging technique, you can be regarded as having mastered the true essence, as for the skills, the old man has run out of oil and has no power to teach you!"

Seeing that Yang Dingtian's remnant soul was getting weaker and weaker, Yun Zhan knew that he was really already running out of oil as he said.

"I don't know what the seniors have unfulfilled wishes, the juniors are willing to do their best to complete it for you!" Yun Zhan bowed.

Yang Dingtian passed on his sword-forging skills, and Yun Zhan also wanted to repay him for his favor.

"Alas!" Yang Dingtian sighed softly: "If the old man has no regrets in this life, but it is also a lie, the old man's biggest wish now is to hope to be able to hand the sword Dao invincible and the Dao Qianji, the thief father and son, but at this time they have completely controlled the Sword Casting Valley, how can you be the opponent of their father and son, this revenge, don't revenge!"

"But the old man really has something to ask you for!"

Saying that, Yang Dingtian waved his hand, and saw a corpse flying in the depths of the fiery red space, and when he stayed in front of Yun Zhan, he saw the truth, but it looked exactly the same as the remnant soul of Yang Dingtian.

"This is the old man's body, I just hope you can find a good place for the old man, so that the old man can be buried in the ground, so as not to expose the corpse wilderness!" Yang Dingtian finished speaking, and then took off a ring from his corpse's hand.

Yang Dingtian gently touched the ring, and a blue gem inlaid in the ring suddenly flashed with a flash of light.

"Whoa!—"

In the middle of the air, piles of colorful metal suddenly fell, it seems that there must be nearly 10,000 catties to say the least, but from the appearance, each of them is not ordinary, definitely not worse than Xuantie.

However, before Yun Zhan could tell what kind of materials these were, Yang Dingtian waved his hand, and these metals suddenly roared, passing through the spatial diaphragm of the Fire Spirit Bead, and only heard two booms, obviously being blasted into the mountain by Yang Dingtian.

"These materials, each of them is priceless, with your current ability, it is not a blessing or a curse to leave you, if you have enough strength in the future, you will come and take it out again!"

"There is still a book left in this "Sword Casting Notes", which is the old man's perception when he was casting swords all his life, if you have any questions in the future, you can look through it, and you can find the answer from above!"

"Drop blood and recognize the Lord!"

Yun Zhan bit his finger and dripped into the gem inlaid on the Qiankun Ring, his mind sank into the Qiankun Ring in his hand, and immediately a stream of information poured into his mind, which was about the items contained in the space of the Qiankun Ring.

Different from the space of the fire spirit bead, the space of this Qiankun ring is much smaller, and it cannot include living creatures in it, but there are advantages and disadvantages, the owner of the Qiankun ring can control it at any time, and only need a thought, you can take out the things inside anytime and anywhere.

"Hmm!?" However, after Yun Zhan General recognized the Qiankun Ring in his hand with blood, he found that in addition to the "Sword Casting Notes" that Yang Dingtian said, there were also a large number of ores, but unlike the divine materials that Yang Dingtian had taken out before, this pile of ores did not look like the slightest brilliance.

"This is just ordinary iron ore, since you have understood the truth of refining into steel, then use it to forge a sword......"

Speaking of this, Yang Dingtian's remnant soul was getting weaker and weaker, and it was obvious that the limit was approaching, but he didn't have the slightest fear.

And he cast it ...... Sword...... Let's go!" As the remnant soul gradually collapsed, Yang Dingtian's voice became weaker and weaker: "Now that ...... Red Sky Venerable...... Still outside, you're ...... Can't go out, as for this...... Fire Spirit Orb...... I've given it to you, too, but that's ...... The symbol of the Lord of the Sword Forge Valley, you must not ...... Show it to others easily, or ......"

Otherwise, Yang Dingtian couldn't say it after all, the remnant soul had disappeared into nothingness, and the dignified Sword Casting Valley Lord finally came to an end!

"Congratulations to the seniors!" Yun Zhan clenched his fists and bowed, and after a long time, he got up and took out the iron ore in the Qiankun ring, and then looked at the corpse of Yang Dingtian and said apologetically: "I have wronged my seniors!"

Saying that, Yun Zhan included Yang Dingtian's corpse in the Qiankun Ring, after all, in the face of a corpse, no one can deal with it calmly.

After doing all this, Yun Zhan turned to look at the pile of iron ore taken out of the Qiankun Ring, which looked like it was a hundred tons at least, like a small mountain.

"Let me use these to forge a sword, but what do you use to melt it!" Looking at this mountain-like iron ore, Yun Zhan had a headache, although the Nine Heavens Divine Fire was quietly suspended in front of him, but Yun Zhan thought to himself with his current spiritual power, I am afraid it would be difficult to control it.

If you throw iron ore into the Divine Fire, firstly, there is too much iron ore, and secondly, the temperature of the Divine Fire is too high, even the outermost Tianyi Divine Fire is enough to burn this iron ore to ashes!

"Squeak!" But at this time, Ahri ran over, before Yun Zhan tempered his body in the fire lotus, Ahri was bored, and now he saw that Yun Zhan was fine, so he hurriedly ran over.

"There it is!" Seeing Ahri, who was blinking a pair of big black jewel-like eyes and looking at him, Yun Zhan's mind flashed, and he suddenly had an idea.

"Ahri, do me a favor!" Yun Zhan said and pointed to the pile of iron ore, and said to Ahri**: "If you help me refine this pile of iron ore, when you get out, I will roast you a lot of barbecue meat and let you eat to your heart's content!"

Ahri's beast fire is extremely hot, and it has recently devoured a lot of divine fire, and its power must be even greater, so it is definitely not difficult to melt these iron ores.

"Squeak!" As soon as he heard that he had his favorite barbecue to eat, Ahri immediately drooled, but the thought of melting all the iron ore like this hill made Ahri feel a lot of pressure instantly.

However, as a foodie, Ahri finally couldn't resist in the face of the barbecue, and it took more than a day to melt all the iron ore.

Although these iron ores are as many as hundreds of tons, in front of Ahri's beast fire, they are still melted into molten iron in an instant, and a total of tens of thousands of catties of iron are refined, but these are rough refining, which can only be regarded as pig iron, and it takes a lot of process to cast a sword with this.

"If you cast a sword, what kind of sword is it good to cast!?" Ahri was already so tired that he lay on the side, and Yun Zhan thought about it, what kind of sword should be cast, although he already had a black crystal flying sword, but at that time, the hole cards must be used at a critical moment.

And what Yun Zhan is casting now must be his own sword, just like Situ Dashao's Heavenly Fire Sword, which complements his "Fire Swordsmanship", Qin Zhongliu's Thundering Sword makes "Thundering Swordsmanship" even more powerful.

Yun Zhan must first decide the swordsmanship he wants to use, and then forge a new sword according to the characteristics of the swordsmanship.

Although "Remnant Swordsmanship" is good, but after all, it is a clever victory, the real power is still limited, at most it is equivalent to intermediate swordsmanship, at this time, Yun Zhan is already the strength of the seven heavens after tomorrow, which is equivalent to the good hand among the acquired ones, and the swordsmanship used should also be high-level swordsmanship.

So Yun Zhan spent nearly half a day, constantly checking the swordsmanship in his mind.

"Smack!-"

In the end, Yun Zhan clapped his legs and finally decided on the swordsmanship he was going to practice.

"The heavy sword has no edge, and it is not skillful!" Yun Zhan muttered.

This sentence was said by Wei Nie, the sage of Shushan, this sage can be said to be the most amazing and brilliant figure in the 10,000-year history of Shushan, and he definitely has the potential to become a sword immortal;

Wei Nie can slay the Demon Dao Sect Master with a disabled body, naturally there is something extraordinary, that is his physical body, he is also the only one in the 10,000-year history of Shushan who has achieved physical sanctification, and he can split mountains and seas with a gesture.

And this Shushan sage Wei Nie was unable to cultivate sword qi in this life because of his self-abandonment, so he created a set of swordsmanship, which was extremely simple and divided into two layers.

The first layer is lightweight, Yun Zhan has seen Wei Nie's sword in the Shushan Sword Shrine, it is made of the world's fine gold, and the weight is up to 10,000 catties, but in Wei Nie's hands, it is like an ordinary sword, swinging freely.

The second layer is as light as it is heavy, and the grass mustard starts, but it can also be like holding Mount Tai, and holding it to cut the sun, moon and stars.

This "Heavy Sword Technique" is said to be swordsmanship, but in fact, it is more like a kind of sword intent, and it is Wei Nie's comprehension of swordsmanship.

And this "Heavy Sword Technique" is as the name suggests, as you can see from the name, if you want to practice it, you have to have a heavy sword.

Yun Zhan had seen Wei Nie's predecessor's sword in the sword mound beforehand, it was an extremely heavy heavy sword, with Yun Zhan's strength at that time, he felt that it was difficult to pull it out, not to mention hundreds of thousands of catties.

Of course, with Yun Zhan's current strength, this heavy sword can't be too heavy, a hundred or ten catties is enough, if it's too heavy, it will be difficult to play, and if it's too light, it can't show the indomitable power of "Heavy Sword Technique".

After everything was decided, Yun Zhan got up, lifted a piece of pig iron of thirty catties, and forcefully placed it into the Nine Heavens Divine Fire.

There were too many iron ores before, and if the iron ore was thrown into the divine fire, even the outermost Tianyi divine fire would be enough to burn it to ashes, and it was the cloud battle that made Ahri serve as a coolie.

The temperature of the Nine Heavens Divine Fire was too high, and as soon as thirty catties of pig iron were thrown into it, it melted instantly, and in a blink of an eye, most of it had been burned, leaving less than half a catty.

Yun Zhan constantly threw the pig iron into the divine fire, and with the help of the divine fire to remove impurities, the whole ten thousand catties of pig iron, after the removal of the divine fire, there were only two hundred catties left.

"I'm afraid this is already comparable to the essence of iron!" Yun Zhan said secretly.

You must know that Xuantie is also extracted from pig iron, but ordinary swordsmiths, where can they be like Yun Zhan, with the help of the Nine Heavens Divine Fire, they can only melt with mortal fire and keep beating.
