Reader Welfare Activities: The first answer-and-win contest.

Purpose: To give back to readers' support, and exercise everyone's brainpower, strive to create the next strongest brain, board the world brainpower stage, and win glory for the country! Let the brilliance of Xueba spread all over the world.

Organizer: Well, it's me, the man who learns to dominate-the author bacteria!

Specific content: To make a long story short, to put it simply, every two or three days I will write a title in the "Author's Word" of a certain chapter (which one is uncertain). Then, I will specify an answering area at the end of the chapter. Just write the answer in this chapter here.

Rules: ① In this chapter, the book friend who answers correctly and is the first to answer correctly will be rewarded.

②, the number of answers per person cannot exceed twice, even if the answer is correct after two times, the answer will be invalidated.

③ It is forbidden to brush the building maliciously, otherwise it is directly muted.

④ Some questions require not only the correct answer, but also the steps to solve the problem. Otherwise, it is considered wrong. I will indicate the questions that need to be solved.

⑤The answer must be done in this chapter of the prescribed paragraph, and the answer in other paragraphs will be considered invalid.

⑥ This activity is only for starting readers. If you want to participate in other genuine channels or readers who watch pirated editions, you can download the original app from the starting point to read ~www.readwn.com~ There are some questions that may not be described in words. At this time, I will use pictures The form is posted in the v group.

Reward: Each winner will get 8.88 yuan Xueba red envelope! ! ! ! 8.88 yuan! !

After each session, the top three book friends who have won the prizes will receive mysterious rewards.

How to receive awards: On the second day of each question, I will explain in the official chapter who the book friends of the previous issue are. Then, the book friend enters the group private chat and I can receive the red envelope.

The time limit for receiving the prize is one day. That is 24 hours after I said in the chapter that "xxx got the red envelope of the last period of Xueba". If no one receives it after the time has passed, I will send the red envelope as a benefit to the group.

Hmm, finally, finally!

The right to interpret this event belongs to the organizer!

…………

Spoiler alert, the next chapter will have the first issue, welcome to challenge it!
