Suddenly, Mu Guangming turned around, handed the iron essence into the palm of Xu Yi, and said with a smile, "I understand. It must be the power of hard work, willpower, and Lei Ting's power during the battle. They appeared in sequence and circulated endlessly. They were absorbed by the iron essence and formed an internal circulation. Only then did the iron essence, which was purely uncontaminated by foreign matter, completely polluted."
Iron essence is similar to source iron and is also the metallic raw material in Pure Five Elements Raw Material. This type of Pure Five Elements Raw Material is the most difficult to pollute.
This is also the fundamental reason why Xu Yi has repeatedly used iron essence to form shields to defend himself, but the iron essence has always remained intact.
Mu Guangming's guess is good. The reason why the iron spirits were polluted is actually that Xu Yi suffered from repeated wars. The iron spirits were used extensively in the wars. They were first besieged by eight thousand Golden Talisman Army. As the main defense force, the iron spirits were the first to bear the brunt.
The gold medal that makes up Golden Armored Giant God is nourished by the blood of the heart and enhanced by the power of the talisman. The iron essence is being eroded by the power of the blood.
After that, Xu Yi was attacked by Dragon Lock Imperial Qi again. Although he was protected by the iron spirit, he was seriously injured. And this Dragon Lock Imperial Qi, in the final analysis, is the power of wish, which is the power of the wish of the billions of living beings in Greater Vietnam to recognize the royal family.
Finally, Nine Heavens True Dragon Sword led the power of Lei Ting to attack.
Three encounters, all imposed on Tie Jing, formed such a perfect internal cycle that completely locked Tie Jing to death.
Speaking of which, this ending is not the worst for Tie Jing. Not only that, it is also a bit of a blessing in disguise.
If it weren't for the power of hard work, will, and Lei Ting, which formed a perfect internal circulation, the Iron Spirit would only shrink significantly under such a fierce offensive, and eventually be completely eliminated. How could it be preserved?
"If it weren't for chance and a gift from God, where would this piece of iron essence be? It's really a treasure. I really don't know what this iron essence will look like after it is restored."
Mu Guangming was full of praise and threw the iron essence to Xu Yi with a smile.
Xu Yi was overjoyed. Mu Guangming said so. Obviously, Yin-Yang Two Qi can be used to warm and regulate iron essence. At that moment, he said, "I want this Yin-Yang Two Qi. Thank you Brother Guangming for informing me."
Xu Yi was skillfully operating the instrument, but when he saw the light flickering, Golden Token inserted in the card slot turned purple in an instant, with a score of more than 1,300, but it did not move at all., then, there was another jingling sound, and the copper bottle containing Yin-Yang Two Qi slid out of the box, Xu Yi took it, and put it into Sumeru Ring.
Yin-Yang Two Qi was an unexpected surprise. After it was over, the focus of Xu Yi naturally shifted to the mid-level Thunder Spirit Stone, and he immediately expressed his feelings to Mu Guangming.
Manager Mu, who spoke little and had an air of dignity, inexplicably made him feel trustworthy.
Mu Guangming said, "Mid-grade Thunder Spirit Stone? There are two of them here. You have the Thunder Cat Bear demon core of the Mid-stage Tongyu Realm. You only need one hundred points to exchange for one. As for that one The Thunder Cat Bear demon core of the Early-stage Tongyu Realm is not qualified to exchange for the mid-grade Spirit Stone. If you want to obtain it, you can only spend 100% of the Fei Wu value, plus 20,000 spiritual stones."
Even though Xu Yi had been mentally prepared, he was still taken aback. The 500 points were only exchanged for one exchange opportunity, and 20,000 spirit stones had to be paid separately.
As far as he knew, the price difference between Five Elements Spirit Stone and ordinary spirit stones was about two thousand times, and the price difference between mid-grade Spirit Stone and ordinary spirit stones was also about two thousand times. If replaced according to this theory, it would be 40,000 ordinary spirit stones to replace one medium-grade thunder-attribute spirit stone.
However, such a simple reasoning may not be absolutely correct. In short, no matter which angle you look at it, exchanging twenty thousand spirit stones for one medium-grade thunder attribute spirit stone is worth thousands of dollars.
Of course, after counting the precious 500 points, we have to carefully analyze whether the value is worth it. After all, the 500 points means five Fire Spirit Stone. Calculating the 500 points, it is worth more than ten thousand spiritual stones.
Adding the two phases together, the price of a medium-grade Thunder Spirit Stone is undoubtedly more than 30,000 spiritual stones.
However, at this moment, Xu Yi is not thinking about whether it is worth it or not. The middle-grade Thunder Spirit Stone is something he must get, and he must get it.
But at the moment, he still had twenty thousand spirit stones in his bag, so he said, "I wonder if it is allowed to use other things to redeem the spirit stones here."
Mu Guangming said, "Shang Gong Hall is not a chamber of commerce, but it cannot be offset. There is no precedent."
Xu Yi was secretly anxious, "I would like to ask if the exchange can wait for a while until I go to raise spiritual stones and come back."
Mu Guangming said, "I'm afraid you have forgotten that redeeming treasures is also one of the links in the entire trial. It is just the last link. But fundamentally speaking, you are still in the trial. Without Shang Gong Hall, once the trial is over, redeeming treasures will naturally end."
Seeing that Xu Yi was feeling depressed, Mu Guangming said, "That's all, I and Your Excellency hit it off at first sight. Seeing that you really want this middle-grade Thunder Spirit Stone, I went to report it, maybe there is room for change. After all, a handsome and outstanding person like you is a rare encounter in a century. An extraordinary person should be treated extremely well."
Xu Yi solemnly clasped his fists, "Thank you, Brother Guangming."
After half a stick of incense, Mu Guangming turned back, with a happy face, and said from afar, "As expected, the superiors agreed to use your Early-stage Tongyu Realm Thunder Cat Bear demon core for mid-term use, but there is a small condition."
Xu Yi felt relieved, then tightened his nerves, "I would like to hear the details."
Mu Guangming said, "It's not a strict requirement, it's just a small vision. The superiors require you to show full goodwill at the appropriate time when the superiors need it, or to meet one of the above requirements within the scope of your ability."
"What kind of conditions are these? It's unheard of. Is it really pie in the sky?"
Xu Yi was secretly surprised, he couldn't figure out the reason why the other party offered such conditions.
Mu Guangming seemed to see the doubts in his heart and said with a smile, "Don't worry, Your Excellency. An outstanding person like you will be the target of all parties wherever you are. I just want to form a good relationship with you, so there is no need to be suspicious."
As soon as these words came out, Xu Yi instantly understood that indeed, he had received too much preferential treatment, whether in Dai Viet or Tianxia Association.
"In this case, I will thank you."
Xu Yi gave a respectful fist hug.
Ten breaths later, two middle-grade pure white jade Thunder Spirit Stone were put into Sumeru Ring, consuming the demon core of two Speech Stage Thunder Cat Bear, and incidentally losing two hundred points.
Afterwards, Xu Yi once again browsed through the items in the exchange equipment. He was a little aimless. There were indeed many precious things among them, either because he had not saved them or because he needed too many spiritual stones.
After browsing for a long time, I finally aimed at two objects. After that, all the spiritual stones in Sumeru Ring were used up, as well as 600 points.
What he exchanged was Array Breaking Stone and Great Evolution Array of Rotation, one to break the formation and the other to protect the formation. Although they are not urgently needed, they can be prepared for emergencies.
