In the process of collecting materials, Yu Hao also learned that void energy is a kind of energy with extremely high purity, which only exists in the universe, and has very harsh birth conditions, it must be a place where stars gather intensively, and there is a large amount of gamma ray irradiation, and it is possible to form it after at least 100,000 years of condensation.

The main effect of the void energy is to increase the potential of human beings, and the price of a drop ranges from 80,000 to 100,000 credits, and it is generally only found in the world of exams in the context of interstellar warfare, such as the world of "Starship Troopers".

As for the so-called divine blood, it is not actually the blood of the real gods, and those creatures that have developed all the thirteen chains of hidden genes in their bodies are called gods, and their blood is divine blood.

The "divine blood" required for "creating a physique" is not the real divine blood, after all, only a strong person at the professor level can encounter a creature of that level in the graduation exam, and only the blood of those creatures descended from the "god" is needed, such as the blood flowing from the green dragon, the white tiger, the vermilion bird, the Xuanwu unicorn, etc. in Chinese legends.

The price of the blood of these creatures also ranges, the fire unicorn from the world of "Fengyun" is a kind of unicorn, and its blood is sold very cheaply, at most 20,000 credits can be done, but the more advanced "divine blood creatures" are very terrifying, and none of the creatures that are already called divine beasts are below the SS level.

Creatures of that level, even if he stood still and asked Yu Hao to collect blood, he would not be able to break through the skin of those creatures to get their blood, and compared to the SS-level strength of humans, maybe those creatures were even stronger.

Yu Hao did find a kind of blood called "Divine Bird Bi Fang's Blood" in the trading market, but this Divine Bird Bi Fang is an S+-level creature, the price of this drop of blood has reached a terrible 500,000 credits, and there are a large number of comprehensive test scores, even if Yu Hao buys it, he can't afford it.

But the low-level "divine blood" is not something that can be bought if you want to, at least it has not appeared in the trading market during this time, but you can publish some information about buying in the trading market, and only need a 1% service fee, and Yu Hao can only rely on this method to buy.

As for the last thing, the "Devouring" Virus, this is the most difficult thing to obtain, because whether it is "Divine Blood" or "Void Energy", although the price is very high, there are still many exam worlds that have the opportunity to obtain them.

However, this "devouring" virus has only appeared in the exam world so far, you know, although there are many classes in the school, the number of realm worlds is unimaginably large, and the difficulty of getting that virus is undoubtedly the greatest.

The bloodline of the ancient god is naturally the most powerful, but although the "Creation Physique" second only to it is very difficult to obtain, but a person like Yu Hao, who pursues perfection, it is impossible for him to be interested in any other bloodline, even if he gets into the tip of the horns, he must get this thing.

"That's right, Spring Outing!" Yu Hao remembered the reward again, ordinary exams are arranged by the principal, they have no choice, but the spring outing is the most special kind of exam, its particularity lies in the fact that the world of the exam is decided by the class teacher!

The danger level of different realms is different, and all the basic rewards are also very different, especially for some difficult exams, maybe the basic credit rewards will reach tens of thousands or even more, and Bai Mengmeng's original plan is an extremely difficult exam world, they only need to play comfortably in it for a few days to come out with more than 10,000 credits.

As the head teacher, Bai Mengmeng can also get 5% of the credit reward from all of them, which is almost 10,000 credits, even if it is a top sophomore like Bai Mengmeng, the average gain for each exam is about 8,000 credits.

Thinking of this, Yu Hao immediately sent a message to Bai Mengmeng.

"Teacher Bai, I have something I want to discuss with you."

"Oh? What's the matter? Bai Mengmeng grinned, this was the first time Yu Hao had something to look for him.

"Can the world of the next exam be replaced by the world of the "extraterrestrial virus"? Yu Hao had already investigated the name of that world a long time ago.

Bai Mengmeng was quiet for a moment, it should be that she was inquiring about the information of that world, and then she said in a somewhat reluctant voice: "Yu Hao, you must know that the spring outing is a very rare reward, the basic reward of the world you said is only three or four thousand credits, this is not only a loss for you alone, but also the entire second class, and me!" ”

"I know." Yu Hao said firmly, "But I want to find a very important thing in that world, and that thing can only be found in that world, which is related to my future growth......

"Oh?" Hearing this, Bai Mengmeng hesitated, "Is it ...... What did you get in the library? ”

"Yes, as long as I get that one thing, my strength will be able to improve by leaps and bounds in a very short period of time, and the overall strength of the class will definitely be improved by a stage at that time."

"Okay, then I'll promise you once, but you kid must not make any mistakes, I can count on you to get rich." Hearing that it was Yu Hao who got the information from the library, Bai Mengmeng had to pay attention to it, and after weighing it, she still agreed to Yu Hao's request.

"Thank you, Mr. Bai!" Yu Hao was ecstatic, in this way, the most troublesome thing is in hand, and this unified examination is also a great creation of his.

Everything has a clue, Yu Hao has devoted himself to the production of bloodline strengthening potions, he has already made arrangements, first improve the team's combat effectiveness and endurance, then first make bloodline strengthening potions for the most important combat power in the class, Fang Ruoyuan and Li Yixiao, and the treatment core Xu Yun.

After nearly a month of research, Yu Hao finally made three bloodline boosters of different colors a few days before the final exam.

Sword Immortal Physique (Elementary): He has an extraordinary talent for swordsmanship, which can make him twice as effective in the cultivation of true yuan power, and is one of the basic systems for cultivating truth. Rating: E-

Nine Yin Divine Vein (First Vein): The Nine Yin Divine Vein is the bloodline body of a god in ancient times, with the supreme power to control the energy from Yin to Cold, and the nine veins are all connected, comparable to the gods. Rating: F.

Tree Elf Bloodline: The first elven bloodline has the power to communicate with nature and condense life, but it is extremely fragile and has a very strong healing ability. Rating: F.

These three bottles of things have almost exhausted all of Yu Hao's free time, if he studies step by step, I'm afraid he won't be able to get it until his sophomore year, and the cost will increase by at least fifty percent, with these things, it will definitely be able to make the three of them more capable of a higher level!
