“Can sucking blood strengthen you?”

Su Yu wasn’t too sure, but he couldn’t absorb the blood here. Otherwise, it would be difficult to explain.

“Stop being restless. When I have money later, I’ll buy some for myself. Ordinary blood isn’t too valuable.”

Previously, he had bought a bottle of ordinary ironwing bird blood worth 5,000 yuan. Naturally, the amount wasn’t much.

In reality, if they were to purchase it in bulk, the price wouldn’t be expensive and there would be a huge discount.

The main point was that no one would purchase ordinary blood in bulk unless…

Su Yu’s gaze flickered. Blood essence was actually refined from ordinary blood. Su Yu couldn’t help but mutter, “Little brother, can you refine blood essence?”

If possible, this was a way to get rich.

There were some civilization masters who could refine essence blood. For every drop they refined, their pay would be quite high.

A drop of blood essence at the Thousand Pound Realm. The Xia Trading Company dared to sell it for 50,000!

In reality, there wasn’t much cost. It was mainly in terms of storage, transportation, and extraction, plus personnel fees.

As for the cost itself… if you went to the Allskies Battlefield and spent 100,000 yuan, you could ask the military to bring back tens or even hundreds of Thousand Pound Realm demon beasts. Those things were trash in the Allskies Battlefield, and the soldiers wouldn’t eat them. There were too many of them and they couldn’t be finished.

The majority of them were in the later stages. The cost of refining blood essence and transportation wasn’t worth it to transport a Thousand Pound Realm demon beast back from the Allskies Battlefield. Unless it was a large-scale transportation, even 50,000 wasn’t worth it.

Naturally, the military also had civilization masters who could directly refine them in the Allskies Battlefield. However, those at the Thousand Pound Realm weren’t very valuable, and civilization masters couldn’t be bothered to take action.

In the past, Su Yu didn’t understand these things too well. However, now that he knew of the existence of civilization masters, he could make some connections and gain a rough understanding.

“Blood characters and divine runes need to absorb blood…”

Su Yu sighed. He felt that he would go bankrupt soon. If blood could nurture divine runes, wouldn’t he have to go and buy them?

He definitely had to buy it!

The nurturing of divine runes was very important.

If his willpower wasn’t enough, he would use other methods to nurture it. It seemed that he would be short of money in the future.

Su Yu was amusing himself in the storeroom. He was so tired that he was sweating profusely when he checked on the corpses.

These corpses were too heavy. As someone at the Origin Opening Realm, he couldn’t move the corpses at all, let alone carry them.

Some of them were piled up together, so he had to move them bit by bit. Otherwise, he wouldn’t be able to see them clearly.

A moment later, Su Yu’s body was covered in blood, looking extremely dirty.

The divine character for “blood” throbbed even more intensely, as though it wanted to come out and suck blood. Since Su Yu had suppressed it, was this thing looking for a fight again?

…

It was only at night when the door to the storeroom opened that Su Yu was released.

Outside the door, Liu Wenyan looked at his dirty appearance. The booklet was filled with dense words, and he revealed a smile.

“Very good!”

He didn’t complain or patronize her. It was very good.

“That’s all for today. We’ll continue tomorrow. We’ll stay here for five days and change locations in five days.”

After Liu Wenyan finished speaking, he thought for a moment and continued, “Previously, Bai Feng taught you to try out the divine language. Of course, you won’t be able to do this now, but you can try to get used to it in advance.”

“The consumption of willpower to outline divine runes is very high. Actually, there’s another shortcut. By using the demon race’s blood essence to outline, the blood essence will naturally contain willpower and origin qi. One will first outline divine runes that possess a divine charm in the outside world before drawing them with their will. This is the normal cultivation method of civilization academy students.

“I didn’t teach you this in the past, but I will do so in the future. Every five days, you can receive a drop of essence blood from me that is suitable for sketching divine runes. The prerequisite is that you complete the course very well!”

Su Yu was excited at first, but he then spoke awkwardly, “Teacher, forget it. I don’t need it.”

It was impossible to expect the academy to reimburse him for the blood essence.

Clearly, if Liu Wenyan wanted to pay out of his own pocket, even if he wanted to redeem it in the academy, he would have to pay 1 merit point.

“I’m talking about the outstanding completion of the course. Do you think I’m giving it to you for free?”

Liu Wenyan snapped, “Do you think you can complete it easily? Maybe in two months, it’ll be considered not bad if you can get a single drop. What is one merit point to me?”

Su Yu was embarrassed. He wanted to say that he had actually completed the outline, but there were still people from the Xia Trading Company beside him, so he held back.

(Let’s wait and see. Besides, the teacher is right. I might not be able to complete the mission he gave me.)

If it wasn’t for the fact that he was used to being killed in the dream realm today, he probably wouldn’t have been able to withstand such a thick stench of blood.

“Let’s go. Go back and have a good rest tonight. Your mission recently is very important. You can put aside your cultivation for Origin Opening Realm for now.”

“Yes, I understand. Teacher, don’t worry. There won’t be any delays.”

“…”

The two of them exchanged a few words before Su Yu returned home and Liu Wenyan returned to the academy.

…

Time passed by.

During the day, Su Yu would learn from Liu Wenyan. At night, his missions were also very important. He would cultivate in the Origin Opening Realm and observe the [Origin Opening Art]. He would also take the time to learn the all-races languages while fighting in the dream realm.

He also began to officially observe and learn the original bone fragments of the Thousand Pound Realm. Even though he couldn’t see them yet, every time he fought against them, it would be beneficial to his willpower.

Bai Feng said that he could see it at most twice a day. As for Su Yu… he could see it at least ten times a day.

He didn’t feel that there was anything wrong with it. In any case, every time he finished reading, his head would ache a little, but it would recover very quickly. It was harmless.

At this moment, Su Yu was so busy that he didn’t have the time to deal with the matter of the “blood” underling wanting to absorb blood.

He would use his willpower to nurture it first. It wouldn’t be too late to slowly test it out when there was more time.

In the blink of an eye, a month had passed.

It was now mid-May.
