One person: I, Daoist Master, am a cultivator of immortality!

After obtaining the Celestial Star Copper, Sun Yao understood the operating principles of this world; it was entirely structured by the Celestial Star Copper. In other words, whoever controls the Celestial Star Copper can freely enter and control this world.

He simply used his spiritual energy to activate the Heavenly Star Copper and disappeared from this world. The next second, he reappeared on the platform of the great tomb in the real world.

"Everyone stop! This pool of water is highly poisonous and cannot be protected by ordinary means."

Upon returning to the platform, Sun Yaozheng saw the disciples of the Unloading Ridge Sect preparing to go into the water to retrieve something and immediately stopped them.

"Master Dao, you're finally back. Judging by the time, you've been gone for about half an hour."

Upon hearing the sound, Qi Tiezui immediately ran to Sun Yao's side. Just moments ago, he had been directing these members of the Unloading Ridge faction, explaining in detail what was valuable and what should be taken.

“These things are all immersed in this toxic pool of water, and your gloves and such are not enough to protect them. I will control the toxic water, and you all go down and take away the valuables as soon as possible.”

After Sun Yao finished speaking, he raised his hands, and the poisonous pool water rose continuously as he raised his hands. Even the poisonous water in the bronze vessels rose up together, leaving not a drop of water behind.

"Everyone, quickly clean up the battlefield and take all the valuables with you."

Seeing that Sun Yao had lifted the entire poisonous pool, Hong Guniang immediately made a decision and ordered everyone to act quickly.

With the coordinated efforts of hundreds and thousands of people, even the magnificent Qingwuzi tomb was looted clean.

After looting all the valuables from the entire tomb, they drove back to Shacheng. They left with only 10 trucks, but returned with a full 30. Ordinary people, merely observing, gossiped about where those 30 trucks came from and what they were doing there. Those from the Nine Gates who knew the inside story, however, gasped in astonishment—what kind of tomb could possibly yield so much treasure!

Upon returning to Shacheng, Sun Yao did not receive any visitors. Instead, he locked himself in his room and began his seclusion. This time, with the Heavenly Star Copper in hand, coupled with the true dragon body left behind after the Fire Flood Dragon's demise, the magical artifacts in Sun Yao's hands were about to experience a tremendous surge in power.

The most important thing right now is to strengthen the Thunder Pool Flying Sword. With Sun Yao's current cultivation level, the Thunder Pool Flying Sword, which is only made of fine iron, is no longer sufficient for his use.

However, he did not intend to use the Celestial Star Copper to enhance the Thunder Pool Flying Sword, because during the past three years, he had examined the Fire Flood Dragon's body after its transformation, and found a Dragon Pearl within it. If the Dragon Pearl were combined with the Celestial Star Copper, the combined power of both could be unleashed.

However, it's clear that the Dragon Balls are not very compatible with the Celestial Star Copper and the Thunder Pool Flying Sword. It's not that they can't be used, but rather that they are not the most suitable.

Neither Dragon Balls nor Celestial Copper can achieve their maximum effect on flying swords, but Dragon Horns are a good fit.

However, what needs to be incorporated is that pair of dragon horns. The material of the Thunder Pool Flying Sword is really too poor. If it were really made with real dragon horns, it would be better to just make a new pair of flying swords.

The more Sun Yao pondered it, the better he felt this decision was. He could use two dragon horns to strengthen the Thunder Pool Flying Sword, and then use two true dragon horns to forge two separate flying swords, or even forge two true dragon horns into one flying sword. Even legendary sword immortals might not only have one flying sword.

Most importantly, the fire dragon had already become a true dragon after its transformation. Even though this true dragon body was dead, it was still not something that could be divided by ordinary iron.

With no other option, Sun Yao could only choose to refine the two dragon horns into the Thunder Pool Flying Sword, so that he could possess a weapon powerful enough to sever the body of a true dragon.

After Sun Yao's investigation, it was found that the two dragon horns and the Thunder Pool Flying Sword were a perfect match. These two dragon horns were knocked off by tribulation lightning when the Fire Dragon was undergoing its tribulation, and they contained the unparalleled power of tribulation lightning.

With the power of this tribulation lightning, other types of magical artifacts simply cannot fuse with these two dragon horns. However, for a lightning-attribute magical artifact like the Thunder Pool Flying Sword, this tribulation lightning power is like adding wings to a tiger, almost doubling its power.

Sun Yao first roughly sketched out the blueprints, and then began preparing the materials for forging the weapon. This time, strengthening the Thunder Pool Flying Sword wouldn't be achieved with just these two dragon horns. When he previously forged the Thunder Pool Flying Sword, he used fine iron, which was made by layering high-carbon steel and wrought iron. Therefore, the materials used for the Thunder Pool Flying Sword weren't rare, nor were they particularly powerful.

Since the plan was to reforge the Thunder Pool Flying Sword, it was natural to prepare the materials. Sun Yao had already sent a letter to the Northeast before coming to Shacheng, purchasing three tons of cold iron and red gold copper mother metal from the Chuma family with gold.

Besides cold iron and red gold copper mother, Sun Yao thought of another material: diamond, the hardest substance on Earth. Coincidentally, the Huguang region was a well-known diamond mining area.

The diamond deposits in Hunan are mainly placer deposits, primarily located in the Yuan River basin. They are scattered and of low grade, but of high quality, with gem-quality diamonds accounting for approximately 40%. Legend has it that scattered diamond deposits were discovered in the Yuan River basin of Hunan during the Ming Dynasty.

What would it look like if a dragon's horn were combined with diamond? How different are the diamonds in this world from those in myths and legends?

So he immediately gave orders to have diamonds mined in the Yuan River area, while he himself worked on designing blueprints for other magical artifacts.

About two months later, Sun Yaocai finally gathered enough diamond materials for the two flying swords. For two whole months, he mobilized a total of 3 people to mine diamonds in the Yuan River region. Sun Yaocai obtained enough diamond materials to construct two flying swords, but these diamonds were all microparticles; to make a sword, he still needed to forge them.

After obtaining these materials, Sun Yao immediately put the diamond particles into the Heavenly Star Torch Furnace. To forge two flying swords, the first thing to do was to create two sword blanks. For a sword, the sword blank is the most important.

The best material for forging the sword blank is undoubtedly diamond, at least in this world, diamond is the hardest substance that he can currently mine.
