Chapter 190 Two years, level five

"Uh, what is this mandatory mission...?"

The window lady with a mask looked at him with sympathy, and comforted him in a soft tone.

"It is the number of missions you need to participate in with the biochemical group. In addition to the mandatory participation, the rewards for the mandatory missions are no different from those for ordinary missions."

"Then how many mandatory missions are usually required for the biochemical division of the expedition group?"

"Dear Mr. Level 4 Biochemical Division, it is usually once, and there are three opportunities for free missions every year. The most is two mandatory missions. This is the first time I have seen four missions like you being forced to participate."

This Cen Tianxing is still a bit cruel. It seems that he has directly maxed out the number of missions he has to go out in a year.

"In fact, there are also some more radical or more money-strapped biochemical divisions who choose to participate in four missions a year. There are also situations like you."

The lady continued to comfort him kindly. In her opinion, except for the top few in the fourth level, few biochemical divisions can endure the intensity of four consecutive missions in a year. The possibility is even slimmer since the biochemical division in front of him looks so young.

Think of this as hospice care. Thinking of this, the lady's extension became more gentle.

Xu Yi didn't expect that he was already a dead person in the eyes of others. He was a little puzzled by the sudden kindness of the window lady.

"Okay, I know. Please help me register the expedition number and information."

"Okay, you haven't participated in an expedition yet. You are just a first-level explorer. The expedition points are zero. The current authority can only be exchanged for ordinary biochemical supplements and some supplies."

"What else can be exchanged at a higher level?"

Xu Yi's goal is the secret method and modulation information, so he is naturally quite interested in this.

"The secrets and techniques of biochemists, the data on the modulation of biochemical beasts, but these should not be lacking for the biochemists who can join the expedition team, right? More biochemists still choose to change to some more niche equipment, as well as some advanced auxiliary extracts for cultivation."

Xu Yi secretly said, lacking, the secrets and biochemical beast modulation materials are lacking anyway, and asked about some ways to obtain points, and then took the explorer certificate that the window lady had issued for him and left the window.

At the door of the business processing hall, Xu Yi successfully found Du Yuanfei, Hu Zi and Su Lishi. At this time, there were still a few minutes before three o'clock, and Cen Tianxing arrived soon.

He was a little surprised that the four people had no signs of being late at all, and seemed to be more stupid than he imagined. Originally, he was prepared to use someone as a target to establish his authority if he was late, but now he had no way to start.

Could it be that all his thoughts were seen by these four biochemists who came from remote villages?

Not really, but for the first time he had doubts about the four people, but then he thought, what can four level 4 biochemists do?

It won't affect his level 5 biochemist either...

After eliminating his worries, he regained his composure. No matter if they are stupid or not, just listen now!

"The target of this expedition is Shelter No. 36, where a large-scale tide of phantom puppets has appeared..."

...

Two years passed in a blink of an eye. In the past two years, Xu Yi completed eight tasks, and more than half of his points were exchanged for secret methods and biochemical beast modulation methods.

A small part was exchanged for auxiliary agents for cultivation, which greatly increased the accumulation speed of his radiation energy and reached the threshold of a level 5 biochemist.

In the past two years, the eyes of the young lady at the window of the business center have gradually changed from sympathy to admiration, and then to weirdness.

In her opinion, it was a little unreasonable that this young biochemist invested most of the resources he had obtained from the expedition missions into the biochemist secrets and bio-beast modulation methods that had nothing to do with him.

But he was able to survive with only a small part of the resources, and he exchanged all of them for cultivation auxiliary extractants. There must be a way.

It might be that her vision was too low. The secrets and modulation methods exchanged by biochemists were not allowed to be passed on to others privately. She really couldn't see what use these intermediate and advanced secrets and modulation methods could be, but he survived...

The cultivation auxiliary extractants exchanged by Xu Yi with a small part of his points helped him quickly reach a total radiation of 2,000 roentgens. Compared with other biochemists who also took on many difficult expedition missions a year, he spent very little on secrets.

The Wall of Slowness and the Slowness Domain he had just exchanged were the only two secrets he had exchanged. These two were the fourth and fifth level advancements of the Slowness Ray. These soft control secret arts, when in his hands, were as powerful as hard control when used with annihilation radiation, and the cost-effectiveness was very high.

Xu Yi had not forgotten the high-end secret arts, the fourth and fifth level annihilation series secret arts that he had snatched from Dean Rong.

As for the special equipment for some illusion puppets and the materials for biochemical beast modulation, Xu Yi chose to get them all for free, so that he used the points saved to exchange for the secret arts and biochemical beast modulation materials stored in the Fifth Shelter.

Because he had communicated with Du Yuanfei and Su Lishi, the secret arts and materials exchanged by the few people were staggered to prevent the First Military University from not counting their credits on this basis.

After this trip, the three of them could be said to have made a lot of money, and each of them could get 50 to 60 credits after returning.

The things that Hu Zi exchanged seemed a little more normal, including the modulation materials for biochemical beasts, the refining agents for auxiliary cultivation, and many professional large-scale equipment. He was the one who got free for a long time.

Xu Yi didn't know why he exchanged so many seemingly useless equipment, but Hu Zi's exchange style was normal, which also reduced Cen Tianxing's vigilance against them in the past two years.

In the past two years, the new and old faces of the Fourth Biochemical Expedition Group came and went, and the personnel turnover was very fast. Even Cen Tianxing did not lead the team three times, but Xu Yi and the other four were always there, and they were also trusted old faces in the group.

In addition, during this period, the four people broke through to level five one after another. Cen Tianxing verbally promised that after this mission, he would give the four people a long vacation so that they could go back to Fortress No. 76 to take a look.

However, according to the four people's understanding of Cen Tianxing, this old fox, most of the time, there was a problem with this mission, and it was possible that the four people did not have a chance to come back.

The algorithm for points is partly based on military exploits and killings, and the other part is the evaluation of the group leader.

In eight missions, the four people had the opportunity to have their points deducted by this old guy, but this old guy never let it go once.

This was a big grudge, otherwise Xu Yi and the other two would have at least earned another six or seven credits.

Moreover, they were often assigned the task of clearing mines and clearing pits. Even though the four of them were gods, it was too difficult to kill them. If they were ordinary biochemists, they would have died in some mission.
