The elder touched the stone tablet with emotion and said, "Xiang Ru, do you know what this Heavenly Burial Mountain is used for?"
Xiang Nan said, "Isn't it used as a tomb?"
The elder smiled and shook his head, "Before the first sect master was buried, this place was not a tomb."
"No one would be so unlucky as to create a tomb mountain for themselves."
"This is a place that the The Dark Underworld Sect has specially built for our Azure Underworld Sect's number one Sect Master to cross the tribulation."
Xiang Nan sucked in a breath of cold air, "Is this the refuge of a ninth level Heavenly Tribulation martial artist when facing the lightning tribulation?"
The elder nodded, "This mountain contains extremely powerful profound dao power. It can help my first sect master withstand a portion of the lightning tribulation power."
"Unfortunately, in the end, the Old Sect Master still failed to cross the tribulation and died on this mountain. In addition to the Old Sect Master's death, today, more than a thousand years later, our Azure Underworld Sect has never produced a single expert at the ninth level of the Heavenly Tribulation."
"Therefore, this mountain was naturally used as a tomb mountain."
"The stone tablet you saw was a mountain rock that was accidentally struck by lightning tribulation back then."
Xiang Nan was instantly shocked. The stone stele that had been struck by the lightning tribulation?
How powerful was this thing's lightning attribute?
"Such an important thing" Xiang Nan hesitated. After all, this stone tablet was of far-reaching significance to the Azure Underworld Sect.
The elder sighed and shook his head, "Let go of what should be. Sooner or later, let go of it. If we continue to hold onto the glory of the old sect master, it will only delay our Dao Heart."
At this point, the elder's hand flickered with a strong light. He cut a long, translucent stone from the stone tablet and handed it to Xiang Nan. "This forging material is not small. It should be able to satisfy your needs."
Xiang Nan first bowed deeply to the stone tablet, then received the stone bar with both hands. After thanking him for his kindness, he left on his own.
Holding this piece of stone, Xiang Nan's heart surged. It was absolutely fake to say that he wasn't excited.
The sense of crisis in his heart grew heavier and heavier.
Although he possessed ten times the strength of his physical body, this heaven-defying advantage would soon disappear.
After all the martial artists in the world cultivated half-demon bodies, or their modified golden bodies could not be broken, the so-called tenfold physical body strength would not be ten times stronger.
If a Heavenly Profound Sect disciple with a half-demon body and five times the strength of his physical body stood in front of Xiang Nan, then to him, the so-called ten times of Xiang Nan was actually only twice as strong as him.
If he encountered an enemy six or even seven times his physical strength, ten times Xiang Nan's would not even be enough.
Someone once said that the great era of martial arts had arrived, and the collective increase in the physical strength of all martial artists in the world was a great trend that could not be stopped.
Xiang Nan had thought about how he could continue to widen the gap in strength between himself and the world's martial artists. At present, it seemed that he could only start with the strength of his Yuan Qi.
A heavenly-grade weapon with lightning attributes was one of the main ways to increase the strength of one's Yuan Qi.
Xiang Nan found the Dream butterfly and immediately took her away from the Azure Underworld Sect to the vast primeval forest.
After Xiang Nan finished setting up the pill furnace and the materials that had undergone the lightning tribulation, he glanced at the Dream butterfly not far away.
Dream butterfly was sitting under the tree with a lazy expression on her face. She looked at Xiang Nan with a faint smile.
Xiang Nan frowned. In his heart, the scene of him and Dream butterfly meeting again shouldn't be so calm as water. Dream butterfly wasn't even the slightest bit excited.
Xiang Nan did not pay too much attention to her and immediately threw himself into the process of forging.
As for Dream butterfly, Xiang Nan had nothing to hide anymore. He could directly forge weapons in front of her.
He first threw the Dragon Blood Saber into the smelting furnace and used the Yuan Qi flames to heat the Dragon Blood Saber until it turned red before throwing the stone into the furnace.
Immediately after, Xiang Nan discovered that an awkward scene had appeared!
No matter how hard he tried, even if he used his strength to suck milk, his Yuan Qi flames could not shake the stone bar in the slightest!
The stone bar stood quietly in the smelting furnace. It didn't even have the slightest bit of temperature. Instead, it felt a little cold.
Xiang Nan recovered his Yuan Qi and gasped for breath. This time, he really had a headache.
"Dream butterfly, I can't melt this forging material." Xiang Nan asked out of breath.
Usually, at this time, Xiang Nan was willing to ask for Dream butterfly's opinion.
The Dream butterfly was already lying on the ground, looking at Xiang Nan lazily and said, "What kind of attribute is that stone bar of yours?"
"Naturally, it's a lightning attribute." Xiang Nan said.
The Dream butterfly giggled and said, "I can see that your artifact forging techniques are very clever, but your experience is obviously inadequate."
"Since this stone bar is a lightning-attributed material, you should use the power of lightning to dissolve it, right?"
"Ah!" Xiang Nan slapped his forehead and thought to himself, "Why didn't I think of it?"
In the Heavenly Grade Weapon Refining Technique, only Xiang Nan was taught how to refine a weapon and how to control the temperature of the weapon, but he was not taught how to deal with the weapon refining materials themselves.
He only knew how to use flames to burn the smelting materials, but he forgot that the properties of the smelting materials were too strong! It was no longer something that flames could handle.
Xiang Nan took a deep breath. He drew heavenly lightning, recovered his Yuan Qi, and sent it back into the smelting furnace.
And this time, once he used his Yuan Qi to connect with the stone bar, he quickly changed his Yuan Qi to White Flame Lightning!
The white lightning exploded in the smelting furnace. The smelting furnace was like a tiny night sky, and thunder rolled in the air.
Seeing this scene, Dream butterfly stood up in shock.
"It really works!" Xiang Nan's forehead was already sweating from exhaustion. He directly used divine lightning to refine the stone strips in exchange for more Yuan Qi consumption.
However, the effect was also remarkable. Under the bombardment of thunder and lightning, the stone bar slowly melted into rolling magma.
Xiang Nan followed the incomparably mysterious Heavenly Grade Weapon Refining Technique and mixed the magma with the Dragon Blood Saber and tempered it.
As soon as he realized that his Yuan Qi was about to run out, he immediately activated Heavenly Lightning to replenish his Yuan Qi and slowed down the refining process, preventing the Yuan Qi supply from becoming vacant.
After repeating this for five hours, the smelting furnace finally exploded with a loud boom.
The power of the White Flame Blazing Lightning instantly reached its peak, directly shattering the Heavenly Grade Equipment Refining Furnace!
A snow-white saber soared into the sky!
The giant saber was as white as snow and as bright as light!
A dragon roar mixed with thunder rushed into the sky!
Xiang Nan jumped up and grabbed the new saber in his hand. He felt incomparably hot from his hand.
"There is an embryonic form of an artifact spirit?" The Dream butterfly was stunned and said, "Quick! Let your blood in! Use your blood to nourish your artifact spirit!"
Xiang Nan did not expect that Meng Die would suddenly give such a suggestion. Without thinking, he cut his palm with a giant saber.
His blood quickly seeped into the giant saber and disappeared.
Xiang Nan panted violently, his face filled with ecstasy.
This time, the artifact forging actually didn't touch the red demon blood thunder sealed inside the giant saber. This was truly a great fortune! It seemed that the power of the White Flame Blazing Lightning had suppressed the Red Devil Blood Lightning.
