After reading all the pills, Hua Lei spent more than half an hour before finally reading the remaining content on the redemption token.

Finally, he calculated that although the credits used for array disks were used, if the success rate was less than 65%, it might not be cost-effective for him to exchange credits for materials.

For example, the level nine attack formation map he is ready to make - "Wind and Fire Sky Thunder Array". If he exchanges it directly in the redemption token, he will need 800 credits to exchange for one.

The materials for this Fenghuo Tianlei Formation are mainly made of fire-patterned sand, wind-patterned sand and green thunder line. The credits required for these three materials are only 500. In other words, if you cannot rent every two pieces of materials and you can successfully make a array plate, then using credits to exchange materials will be a loss-making transaction.

The same problem also exists among the other array plates he wants to make, the biggest difference is the level 8 array plate he wants to make.

The finished product is only more than 3,000 points, but if you buy the materials directly and make them yourself, you will need to have nearly 2,000 credits.

After Hua Lei calculated all the materials he needed, he roughly estimated that he needed to earn at least 20,000 points in just half a month to prepare enough materials he needed to go to this college entrance examination.

Therefore, after he withdrew from the redemption token, he returned to the mission reward order.

He had a rough look before. Although the tasks from Level 1 to Level 3 are relatively simple and the risks are within ten, the corresponding credits are very small.

The highest nine-star mission in Level 3 has only ten difficulty, but the credits are only more than six hundred.

The task of the reward order starts from level 4, so it is no longer a simple task such as mining, medicinal mining, sending letters, and purification.

The difficulty of the level 4-level one-star mission directly ranges from ten to twenty. It requires hunting a small monster wind wolf in the Yefeng Valley on the southern foot of Qinggao. Hunting a monster can earn 100 credits. The realm of the monster is basically equivalent to the third level of the Qiqiao Realm to the fourth level of the mouth and the fourth level of the mouth and bone realm.

Although the realm of a monster does not seem to be high, the real combat power of a monster will be higher than that of a human cultivator. That is to say, if a practitioner wants to hunt monsters from the third to fourth levels of the Qijiao Realm, he needs to have at least the strength of the fifth to sixth levels of the Qijiao Realm to ensure his safety.

Especially if monsters like Wind Wolf still appear in groups, the difficulty will be even higher.

If you go alone, your strength may not allow it. If you go together, the profit will be too low.

After Hua Lei finished the Level 4 tasks, he found that the basic level 4 tasks were within 30. Although the difficulty was not particularly high, it was not suitable for him now. Either the credits were too small or they were required to work together.

Since he entered the school, he has encountered all kinds of strange encounters, which has also led to basically not knowing any classmates except Wu Xiuxiu in the same dormitory.

So he could only continue to watch the level five tasks, and after looking around, he found that there was not much difference between the level five tasks and the level four tasks, but the ability of the monsters in the level five tasks became stronger.

Even in the fifth-level mission, there are many monsters that cannot be dealt with by the Qiji Realm. Most monsters need to reach the Body Building Realm at least to be able to complete.

Similarly, the level 6 task is even more difficult, most tasks are directly at around 60, and many tasks require even the perfection of the tenth level of the Body Building Realm. Even in Hualin Academy, only a small number of students in the top 50 can reach this level.

No wonder the black robe teacher just now said that he could only receive a level seven task.

Just when Hua Lei was helpless and didn't know what to do, he suddenly discovered that there was a five-star purification task in the CET-6 task. The credits rewarded for the task are not particularly high in the CET-6 task, one thousand credits at a time.

However, the difficulty of this task is particularly eye-catching among a lot of tasks with a difficulty of fifty or sixty, because the difficulty of this task is only ten.

However, the requirements for this task are quite strange, and there is no specific thing to purify.

It was just written in the task details: "The mental power must be at least tenth level of the Body Building Realm to be collected, otherwise you may encounter huge dangers."

"If you receive a task and cause danger to yourself, it has nothing to do with the task publisher, and you will be responsible for all consequences."

The place where the task was taken was not in the academy, but in Qingshan County. Cultivators who think they have strong mental power can go to Qingshan County to collect it.

Qinggao Town is just one of the hundreds of towns under Qingshan County. Although Qingshan County is just one county, it is actually very large in scale.

Hua Lei vaguely remembers the year when he was five years old when he had a sudden sleepy disease. His grandfather once took him to Qingshan County.

In his memory, although Qingshan County has only one county, it is a majestic city at first glance, with great momentum and majesticity.

Therefore, this task received in Qingshan County is surprisingly low at the same time, and the credits are not low at all. You can get one thousand credits for every purification. However, many monsters who have hunted tenth levels of the Body Building Realm just now have only one thousand credits.

You should know that as long as your mental power is strong enough, you can continue to purify it, and there is no upper limit on completing the task.

It is much harder to hunt a monster at the tenth level of the Body Building Realm. After each hunting is completed, you not only have to rest, but also continue to look for new monsters. In contrast, the risk coefficient also soars.

When he saw this, Hua Lei was already very moved. He felt that this task was simply tailored for him.

Although the task does not say what to purify, as long as it is a task issued on the reward order, it has been officially certified. First of all, there is no need to worry that others will not settle the credits after completing it.

Although the above mentioned that insufficient strength may lead to risks, it is only ten difficult, and Hua Lei is very confident in his mental power, so he basically doesn't have to worry about the danger.

Thinking of this, Hua Lei checked this task in the check box behind the reward order task.

After he checked the task, the task information in the reward order was passed to the token of his Hualin Academy.

First, it is used as a certificate for completing the task in the future to receive credits, and second, it is to protect any accidents in the task to facilitate recording and confirming his identity information.

After choosing the task, Hua Lei put away the reward order and the redemption order and headed towards his dormitory.

Although it was just a purification task, he still felt that he needed to go back and prepare for such high credits and unclear statements of such unclear tasks.

Moreover, Qingshan County is quite a short distance from Qinggao College. If you walk on foot, it will definitely not be enough for the college entrance examination.

Only by using the Academy's flying monsters can he travel between the two places in the shortest time. He also has to reserve a few days for himself to make a formation disk.

Although he has also learned the method of formations with Yi Peijue for so long, he has not had much experience in actually engraving the array diagram and array plate by himself.

Therefore, for Hua Lei now, he not only lacks credits but also lacks materials, but also lacks time, and lacks a lot of time.
