Among the options displayed on the payment window, in addition to the option of paying in federal currency, there is another option.

"Contribution value payment?" Chu Nan looked at this option in wonder. "What is contribution value?"

After thinking about it, Chu Nan first closes the payment window, opens help and searches for contribution value.

After reading the relevant explanation, Chu Nan understood.

Originally, the so-called contribution value is the reward value given according to the contribution made by each account on the forum. It can be used to do many things on the forum, including directly buying martial arts.

This thing is probably equivalent to the virtual currency on the forum, but it can only be used on this forum.

Of course, this forum is the largest martial arts related forum of the Earth Federation on the pan Galaxy network. According to the description of this contribution value, it is often even more useful than the real federal currency.

Chu Nan seldom wandered here before, so he looked at his account and found that his contribution value was still pitifully zero. Naturally, he couldn't use it to buy Martial Arts.

After hesitating for a while, Chu Nan jumped out of the section where he bought martial arts and turned to the section where he exchanged martial arts issues.

According to the description of contribution value, if you answer questions here, you will get contribution value rewards according to different questions.

Chu Nan also limited the level of the problem to level F martial arts, then randomly clicked a problem and found that it was a problem about cultivating external skills.

This problem is also attached with a short video, which shows the problem intuitively.

Chu Nan looked at it roughly. He easily saw the problem and gave the answer below.

It took him less than five minutes to solve the problem. Then he changed another question and continued to give the answer easily.

After answering 13 questions about external skills in succession, Chu Nan felt that this was a waste of time, so he limited the questions to internal skills.

The problem of internal breathing skill is more difficult. The main problem is that it is difficult to describe it accurately. However, with his research on low-level internal breathing skill these days, Chu Nan can still easily understand the core of the problem and give an accurate answer.

It has to be said that these problems are strange. Chu Nan didn't even think of some problems. While thinking about solving these problems, he gave him some additional inspiration.

After answering more than 30 questions, Chu Nan calculated that the contribution value should be more than enough, so he stopped to answer.

However, the contribution value of these questions will not be given until the other party adopts the answer. Therefore, although Chu Nan spent an hour answering the questions, in fact, the contribution value he really got is very few.

Chu Nan looked to other places where he could get contribution value, and soon noticed a very eye-catching hint.

"Participate in the forum competition and win the grand prize immediately!"

Chu Nan opened the introduction and took a closer look. He was immediately delighted.

It turns out that this is a martial arts competition held by this martial arts forum. As long as you can win the competition, you will get corresponding rewards.

There are not only contribution value rewards, but also cash rewards and martial arts rewards!

Moreover, compared with other martial arts competitions, this challenge arena competition has one of the biggest advantages, that is, it is not held in reality, but carries out virtual warfare in "Wu soul". Therefore, it does not need a real venue, nor does it need contestants to rush to the competition venue all the way, which saves a lot of time and organization costs, and can be held continuously for a long time, which is unmatched by any real martial arts competition.

After reading the introduction of the challenge arena, Chu Nan couldn't help feeling in his heart.

"Wu Hun" has been launched by nuoyantem chamber of Commerce for nearly two years, and has begun to have a great impact on reality.

I believe there will be more and more virtual martial arts competitions like this in the future.

Of course, Chu Nan doesn't need to think about these things now.

He looked carefully at the rules of the challenge arena competition and found that he could sign up and fight at any time, so he got up and went back to the dormitory without hesitation.

A few minutes later, Chu Nan slowly opened the dormitory door, and a few long and regular snores came out, but the three roommates had fallen into a deep sleep at this time.

Just now Chu Nan went to the grove outside the dormitory in order not to disturb them. Now he has to come back because he wants to participate in the virtual challenge arena.

Glancing over, a silver-white game warehouse was lying in the corner of the dormitory, which reflected the silver light under the faint moonlight outside the window.

This game warehouse is the new type of "Wu soul" game warehouse that Mondeo and sal negotiated with Chu Nan and bought together.

Thinking that he bought the game warehouse from nuoyantem chamber of commerce at an ultra-low preferential price of only 35000 through the relationship of tamkenqi, Mondeo and the three of them looked shocked. Chu Nan couldn't help laughing. He walked past without making a sound at his feet, bent down and slipped into it lightly.

After a while, the login interface of Wu soul appeared in front of Chu Nan.

In fact, because he had been studying the internal breathing skill some time ago, this was the first time he entered the game after the game warehouse was bought back.

Probably because of the new game warehouse, the login interface is much more gorgeous than when Chu Nan logged in through his helmet. Even the personal space after entering the game is much richer than before, and has even become a customizable private space.

Chu Nan first noticed the system information.

Because it has been several months since he last landed in Wuhun, a lot of system information has accumulated.

Chu Nan ignored those meaningless spam messages and focused on the only three friends' messages.

Click to see that all the three messages come from "free stamens".

The first is the usual chat. The second is to ask Chu Nan why he didn't go to school for such a long time after a week.

These two messages are more than four months away from today, which is completely last year.

The third message is less than a week away from today.

"Hey, damn guy, you know what? I've bought a new version of the game warehouse of" Wu soul "and put it in my lab. in the future, I don't have to go back to bed at night. I just lie in the game warehouse and sleep while playing games. How about it? Do you envy it? Come on up quickly, too. I haven't seen you play games for a long time. I'm worried about you."

After reading the news, Chu Nan couldn't help smiling at the corners of his mouth.

He was already suspicious when he heard the sentence "virgin 001" suddenly pop up in Ivy's dream.

Now seeing the last message from the free stamen, Chu Nan's doubt turned into certainty.

This free stamen is Ivy! (to be continued)
