“A year?” While Lin Mu wasn’t restricted by the body cultivation technique, it still felt a little long for him. “When’s the next time the Interworld Teleportation Array will activate?” he asked.

“The Interworld Teleportation Array had activated just a month ago so the next time will be 12 months from now.” The Clerk replied.

“Hmm…” Lin Mu didn’t know where he would be till then. ‘No… after I solve a few problems, I don’t really need to rush anywhere. I can technically wait.’ He thought to himself.

“Would you still like to place a request?” The clerk asked again.

“Yes, please do.” Lin Mu confirmed. “How much will it be?” he inquired.

“Placing a request will cost about twenty Mid Grade Immortal stones, but the cost of the Tyrant Bull marrow might vary depending in the availability. Sir will have to pay half the cost upfront.” The clerk stated.

“Half upfront? But isn’t the cost going to vary? How are you going to determine what the half rate will be?” Lin Mu asked.

“We will consider the half value from the last sale of the Tyrant Bull marrow. If there is any fluctuation, the cost will be adjusted according to the advance paid.” The Clerk explained.

“I see… Very well, what’s the advance cost?” Lin Mu didn’t mind paying it.

“Two thousand six hundred high grade immortal stones.” The clerk answered.

Lin Mu raised a brow hearing this, wondering if he was being overcharged.

“Sir must know that the Tyrant Bull is an immortal beast with great strength. Finding and hunting one will take considerable effort along with the cost of importing it to our world, the charge will be high.” The clerk didn’t want to lose a big sale like this so tried his best in convincing Lin Mu.

If Lin Mu didn’t have the ‘support’ from Lan Bao and Elder Niji, he might not have been able to afford this cost at all.

‘I really need to start generating my own income… I can’t keep on spending like this even if I have a lot.’ Lin Mu felt a little uncomfortable.

“Alright. What will be the cost for other the Immortal essence crystal and to book a slot with the alchemist?” Lin Mu asked next.

“The low grade immortal essence crystal are sold for one Mid grade immortal stone each. While mid grade immortal essence crystals are sold for one high grade immortal stone each.” The clerk replied. “As for booking a slot with the alchemist, sir doesn’t need to pay anything extra. It shall be complementarity for you with how much you’ve already spent.” He added.

While Lin Mu was pleased with the last part, he was a bit concerned about the immortal essence crystal. He certainly knew that there were different grades of Immortal essence crystal just like Immortal stones, the cost was higher by a magnitude.

“Hmm… I’ll take a hundred mid grade immortal essence crystal and a thousand low grade immortal essence crystal then.” Lin Mu decided to get this much for now, as he needed to see how much he could use first.

He hadn’t practiced the Three apertures Invoking technique after all, and didn’t know the consumption. Besides, he would be getting the alchemical pills later too, so they would contribute to his cultivation too.

But it also made him wonder about something.

“Are there no high grade immortal essence crystals or above available?” Lin Mu questioned curiously.

“No, sir. High grade immortal essence crystals are very rare and don’t develop in our mines for hundreds of years. And whenever one is formed, it is sold in the auction house.” The clerk answered. “As for the peak grade immortal essence crystal… there have been no cases of them ever being formed on the Rust Sky world.” He added.

“I see…” Lin Mu furrowed his brows.

“Though if sir wishes to get some, you can refine for them yourself.” The clerk spoke.

“Refine them not mine them?” Lin Mu was puzzled.

“Yes… while you can’t mine them for obvious reasons. There is a way to refine them from another material.” The clerk said in a low voice before leaning in. “If you go to the Desolate Blood Battlefield, you might be able to find something called Blood Essence crystals. These can be further refined and purified into High grade immortal essence crystals.” He revealed.

“Is that so…” Lin Mu decided to keep it in mind. “You take the crystal cards right?” He asked before taking out his newly registered card.

“Of course sir!” The clerk took the crystal card from Lin Mu before placing it into a receptacle that was the perfect size for it.

The crystal card glowed for a moment, before the receptacle ejected it out.

“The payment has been confirmed. I shall bring you the bought items right away.” The clears happily walked away.

He had made a big sale today, and would possibly make another big sale in the future due to Lin Mu asking for an alchemist. From each of these sales, the clerk would be getting a commission, thus it pleased him to no extent.

Lin Mu waited five minutes before the clerk returned.

“Here you go sir,” the clerk handed two pouches to Lin Mu.

One held the low grade immortal essence stones while the second held mid grade immortal essence stones. Lin Mu could tell that they were actually quite heavy as compared to immortal stones.

‘Are immortal essence crystals denser than immortal stones?’ Lin Mu wondered.

After getting these, Lin Mu didn’t leave right away though. Instead, he browsed the place for more things. He wanted to get a look at the body cultivation techniques that were being sold here too.

Lin Mu ended up spending two hours here and learned a few things. The biggest of all being just how good the techniques that Xukong had given him.

‘The techniques here are really bad compared to Senior’s… no wonder the requirements are also high.’ Lin Mu thought to himself.
