"Even though you said that, I, Long Qi, still know that I owe you more, but there's no point in being so fussy about it, so let's just do as you said and let's not owe each other anything."

Long Qi looked at Zhang Mu with a kinder look, and continued, "No matter what your purpose is in coming to Shanxi City, as long as you don't harm your fellow human beings, I can help you."

"Of course not. I won't use the lives of my people to exchange for my own interests." Zhang Mu chuckled, but his tone was firm.

"That's good. Tell me, how can I help you?" Long Qi felt Zhang Mu's sincerity and made a promise to him directly, saying that he would do whatever he could for him.

Zhang Mu was about to refuse, because he had successfully completed the transaction with the Epoch Merchant, but he suddenly remembered something and might really need Long Qi's help, so he said, "Aren't we going to Jinzhong City to clean up the battlefield in a day? I hope you can give me all the beast cores you collected. Of course, I will use Yuanjing, which is the energy behind the zombies' brains, or food in exchange, at a ratio of one to ten. As for if it is not enough, I will keep it on credit and pay it back the next time I come to Shanxi City."

"Yuan Jing, so this is its name?" Long Qi did not respond in a hurry. Instead, he was thinking carefully about what Zhang Mu had just said.

Indeed, there are many terms they don’t know yet. They learned the information from their respective Epoch Merchants through the Epoch Agents. However, the Epoch Agents in Shanxi City seemed to have not communicated with the leader of this gathering place, Long Qi, so he expressed confusion.

After a moment of silence, Long Qi finally spoke. He said slowly, "I can give you the beast core, just according to the ratio you mentioned before. I know its value, but I find that you know much more than us.

Like Long Er told me before, you are much more mysterious than us in the Dragon Group.

If you don't have enough crystals or food, you don't have to buy it on credit, just answer a few questions."

It seemed that Long Qi had never met Jiyuan’s dealers. Zhang Mu answered him easily, “Ask me. I will tell you everything I know.”

"The first question is, can the Yuan Jing be used in conjunction with the Beast Core during advancement? Can it be used normally?" Long Qi first asked the first question in his mind.

"Of course it is possible, but without the advanced breath to attract and extract energy, the normal evolver's absorption capacity for Yuan Crystals is actually very low." Zhang Mu explained to Long Qi patiently, "It can make your energy recovery efficiency in a non-combat state reach twice the original efficiency. As for how much you can recover, it depends on the number of Yuan Crystals."

Long Qi nodded gently, as if recalling something, and continued to ask, "Because when I was advancing, relying on Long Er's intuition, she found the materials needed for my advancement, which were the large amount of Yuan Crystals collected before, or the beast core of a mutant beast with extremely strong mental power that I had slaughtered before, so I succeeded by chance. Is the normal advancement process the same? It requires a matching beast core and a large amount of Yuan Crystals. Because Long Er has always refused to use other beast cores without mental power attributes to complete his advancement."

It turned out that it was relying on Long Er's ability. No wonder, she was indeed very sensitive to danger. However, the wrong advancement was the biggest danger to Long Qi and Long Er standing beside him.

Zhang Mu was not going to hide it anymore and told Long Qi the key point directly, "That's right, to advance as a human, you must find a beast core that matches your attributes, otherwise there is a 70% chance that you will explode and die."

"Seventy percent. Is that so high?"

Long Qi sighed and said, "No wonder Long Er has been unwilling to advance. It turns out that using a beast core of a different attribute will kill him. But where can I find her a mutant beast with the same spiritual attribute as I did last time?"

Zhang Mu suddenly remembered an item hidden in his Epoch Merchant Ring, so he quietly moved his right hand behind him, took out a few diamond-shaped crystals, and shook them in front of Long Qi's eyes, saying, "These are the beast cores of several mutant beasts I encountered on the road before. They are all spiritual. If you give them to Long Er, you can help her advance smoothly."

These are all the remaining Yuan Crystals that Zhang Mu collected from the nightmare bugs last time. He originally planned to give them to Yuan Rui, but now there is obviously a more suitable choice, that is the second-level Yuan Crystal of the old white fox, and its attributes are extremely close to her initial attributes.

Before, Zhang Mu used most of the soul crystals because his own mental power was not very strong, so he needed more mental energy to replenish him. However, Long Er was different. She was a leader among the mental power masters at the first level.

After Long Qi felt the familiar breath, his hands trembled with excitement. This was the key for Long Er to advance to the second level! If Long Er also reached the second level, then it would be much easier for them to realize their ambitions.

"Psychic mutant beasts are so rare, but I can't refuse. How about this? No matter how many beast cores my men collect, I will give them all to you. What do you think?"

Long Qi's smile seemed a little guilty, because really, spiritual mutant beasts were extremely rare.

Zhang Mu didn't care. He originally wanted to give it to Long Qi for free, but since he said so, Zhang Mu didn't hesitate. It was just a matter of each taking what he needed. He replied to Long Qi with a smile.

"make a deal!"
