Lu Tan's expression finally changed. He could never have imagined that Wu Chen's power would be so strong that he could bring the power of the earth-level spiritual treasure to such a terrifying level.
“Click.”
A sharp sound brought his thoughts back to his senses. Lu Tan took a closer look and was even more shocked to see that a crack had appeared on his golden halo.
"How is that possible?"
Looking at this crack, Lu Tan was extremely shocked and could not believe it. He could never have imagined that Wu Chen's power was so strong that he could even shatter the golden circle that he had condensed with all his strength.
The others were also extremely shocked and stunned. They had never expected that Wu Chen's strength was so terrifying. Even Lu Tan, an eighth-level True Martial Realm expert, was no match for him.
"Break it for me."
Wu Chen shouted loudly, holding the Sirius Halberd in his hand, and a pressure eroded down, acting on the crack. The crack expanded rapidly, and in an instant it spread throughout the entire golden circle, which was unable to withstand Wu Chen's power.
"No, there is no way I can lose. Absolutely not."
Lu Tan roared and the power in his body surged and poured into the golden circle. He tried his best to maintain the power of the golden circle and try to save the defeat.
However, no matter how hard he tried, he was unable to reverse the situation.
"Bang!"
Finally, Lu Tan's golden halo could no longer hold on and completely collapsed, turning into endless rain of light radiating from the sky.
"ah."
Lu Tan screamed, and his figure flew backwards, splattering a rain of blood in the air. He fell to the ground in a mess, and the momentum surging around his body also died down in an instant.
Everyone was shocked. Looking at Lu Tan lying on the ground, they couldn't help but gasp. This result was something they had never dreamed of. Lu Tan, a strong man at the eighth level of the Zhenwu Realm, would actually be defeated by a man who was only at the fourth level of the Zhenwu Realm.
After looking at Yan Zhen and the others, Wu Chen turned and left. This time he chose to spare Lu Tan's life because Yan Zhen, Bai Ran and the others were watching. If he killed Lu Tan and the news got out, it would be very bad. After all, he still had to rely on Beichen Academy to obtain some training resources.
After defeating Lu Tan, Wu Chen continued to move forward. He didn't know if his luck had run out, but in the following journey, he gained very little, almost nothing.
"It's time to go out."
Since there was no treasure to be found, there was no need for Wu Chen to stay any longer. Moreover, his harvest this time was already huge enough. So many spiritual treasures were enough for the Dragon Slaying Sword to be upgraded to an earth-grade spiritual treasure.
Time flies, and another half a month has passed. During this half month, Wu Chen either stayed in Tianyin City or went to Tianyin Mountains to wander around and fight some monsters. He was waiting, waiting for the Dragon Slaying Sword to be upgraded. The reason why he wanted to seize so many spiritual treasures was all for the Dragon Slaying Sword, in order to upgrade it. As long as the Dragon Slaying Sword can be successfully upgraded, his strength will also increase greatly.
"Finally finished swallowing it."
Seeing that the Dragon Slaying Sword had finally devoured all the spiritual treasures, Wu Chen showed a relieved smile. The power of the Dragon Slaying Sword was now several times greater than before. It was even more powerful than some Earth-level spiritual treasures. It should be able to advance.
Next, he can just wait for the Dragon Slaying Sword to be upgraded. He wants to see what the scene will be like after the Dragon Slaying Sword is upgraded to an earth-level spiritual treasure.
However, what made Wu Chen feel extremely disappointed was that he waited and waited but still could not see any signs of the Dragon Slaying Sword being promoted, which made him feel very disappointed.
"Why haven't you advanced yet?"
Looking at the Dragon Slaying Sword, Wu Chen didn't understand. He had clearly reached the standard for advancement, but he refused to advance.
Because of anger, he grabbed the Dragon Slaying Sword and threw it out of the window. He was very angry. What kind of a thing is this? It has swallowed so many spiritual treasures and its power is stronger than that of earth-level spiritual treasures, but it refuses to be promoted.
At this time, the Dragon Slaying Sword flew back from the window, emitting brilliant light. It was also very innocent. It originally thought that it only needed to devour a lot of spiritual treasures and absorb enough power to be promoted smoothly. However, it didn't know that things were not as simple as it thought.
Wu Chen gradually calmed down and began to think about the reason. He had absolute confidence in the sword he had refined. There was no doubt that it could be upgraded to a earth-level spiritual treasure.
But where exactly is the problem? Wu Chen thought about it over and over again, but he still couldn't figure it out.
"Oh, right, the Record of Weapon Refining?"
Suddenly, Wu Chen remembered the Treasure Record of Weapon Refining, which was a priceless treasure and a classic work regarded as the Bible by weapon refiners. All his knowledge of weapon refining came from this Treasure Record of Weapon Refining.
He went over the contents of the Weapon Refining Record several times in his mind, looking for the reason. He didn't believe that the Dragon Slaying Sword had no potential for advancement. This was absolutely impossible.
"Is it because of the spirit of the weapon?"
After searching for several times, Wu Chen found the possible reason, perhaps it was because of the lack of weapon spirit.
People have souls, and weapons also have souls. The reason why Lingbao is called Lingbao, which is different from ordinary weapons, is because it has spirituality. In other words, in order to cast a Lingbao, you must inject spirit into it to make the Lingbao spiritual. This spirituality is extremely important to Lingbao.
When the spirituality of a spiritual treasure reaches a certain level, it will transform into an instrument spirit. Such a thing as an instrument spirit absolutely does not exist in a spiritual treasure, even in a top-grade spiritual treasure, because the spirituality is insufficient and it is not enough to transform into an instrument spirit. Even in many earth-grade spiritual treasures, it does not exist. At least, in the Heavenly Wolf Halberd, there is no instrument spirit. As for heaven-grade spiritual treasures, there is definitely an instrument spirit, without a doubt.
However, there are also some high-quality earth-grade spiritual treasures. They have strong spirituality and have undergone a long period of evolution to condense into weapon spirits. This type of earth-grade spiritual treasure is absolutely invincible among the same level of earth-grade spiritual treasures. Among the same level of earth-grade spiritual treasures, no magic weapon can compete with the magic weapon with weapon spirits.
"How can I make it work?"
After finding the crux of the problem, Wu Chen had to consider how to find the spirit. As a spiritual treasure of higher level than ordinary spiritual treasures, the requirements for spirituality of earth-grade spiritual treasures are naturally far higher than those of ordinary spiritual treasures. This is also the reason why earth-grade spiritual treasures are difficult to cast. Even for a master of refining, it is not an easy task to cast an earth-grade spiritual treasure.
