As soon as the sword was empty, Ye Rong's heart was cold, and he left the place in an embarrassed manner.

No matter how ugly the posture is, it is not important to keep the surname, anyway, there is no one else in this Langhuan Jade Cave.

"Huh?"

After Ye Rong stood up, he found that those teak puppets did not chase after him, but dragged their heavy steps to divide into left and right sides, and actually wanted to bypass the bookshelf and get close to him.

"What's going on, it's impossible for the AI that the teak puppet just showed to be so stupid, and it's impossible not to see such a big hole. Why don't you come over directly, and have to take such a long detour to entrap me. ”

Ye Rong was puzzled, but anyway, the current situation was in his favor, if the teak puppet really chased directly from the space where he knocked the bookshelf out, then he would be miserable at this moment.

The teak puppets were still a long distance away from him, Ye Rong first aimed at one of them with a fire talisman and slammed it, waited until they got close, fought hard a few times, and had nowhere to retreat, and then turned over and returned to the previous passage from the middle of the broken bookshelf.

A strange scene happened, the faint red light in the two eye holes of the teak puppet jumped rapidly, and it actually detoured from both ends of the bookshelf to Ye Rong's bag again.

"I see, I see!"

Ye Rong's heart was shocked, he shook his fist violently, and shouted excitedly.

This seemingly powerful and invincible teak puppet was finally found by him to have a weakness, or a design flaw.

When the owner of Lang Huan Jade Cave made these teak puppets, he apparently gave them instructions to protect the bookshelves in the stone hall. Although the bookshelves were already empty at the moment, and they were even smashed by Ye Rong, they were still following this instruction.

Following Ye Rong's steps, directly from the middle of the bookshelf, in the eyes of their limited AI, this is undoubtedly a move that will destroy the bookshelf, so it is absolutely not possible. In other words, no matter what happens, it is impossible for the teak golem to destroy the bookshelf, or even pass through the original place where the bookshelf was standing.

In the middle, there was a lot of place for Ye Rong to take advantage of, especially when he still had a long-range attack method like a fire talisman.

made such a guess in his heart, and Ye Rong had a plan in an instant.

The fire charm drained blood and aimed at the target, blowing up a piece of the wooden armor on the chest of a teak golem after a few rounds. When the teak puppet surrounded itself from both sides again, Ye Rong hit it hard again, and the rotten bookshelf on the other side was also broken.

Sure enough, all the teak puppets were stunned and stopped in place. I thought about it for a while, and then I turned around and made the bag from both ends of the bookshelf again.

Ye Rong took advantage of this, constantly weaving through several rows of bookshelves, and every time he released a few fireballs, he stepped out in one step, so that the teak puppet had no choice but to surround himself stupidly the same way.

The fire talisman damage was very low against the teak puppet, but it still worked under Ye Rong's persistent attack against the same monster.

Five minutes later, the first teak golem fell.

Kill the broken teak golem and gain 120 experience.

"Pretty experienced!"

Ye Rong is very relaxed and comfortable now, no different from visiting the park playground, and he has the leisure and elegance to care about the experience points he has gained.

As the number of teak puppets decreased, Ye Rong became more relaxed, but unfortunately after killing all six teak puppets, nothing was violent except for bringing him 720 points of experience.

The stone hall was carefully scanned by Ye Rong inch by inch, and the thick dust made him sneeze several times in a row, but there was nothing of value except for the old empty bookshelves.

In the end, Ye Rong groped for a raised handle on the stone wall with both hands, and pulled it hard in the direction.

Click-click-click

There was a sudden clicking sound on the smooth stone wall, Ye Rong didn't know what mechanism he had touched, and a stone door automatically came up.

The stone door opened, and Ye Rong stepped in without fear, and there was a world inside, a bright hall.

Countless torches lit the walls, illuminating the hall with no dark corners. Directly in front, there are bluestone steps, slowly rising, and at the top is a huge white jade table.

Ye Rong slowly stepped forward, this Immortal Family Cave Mansion was the first time he had entered, who knew what mechanism would be hidden and waiting for him. The Xianfu key was famous during the closed beta, and he didn't believe that a few teak puppets were all the test.

Carefully stepped on the bluestone steps, until Ye Rong finished the thirty-nine steps, there was still no change.

"This round of testing, is it?"

Ye Rong rubbed his nose, he had already seen that the white jade table was actually a huge chessboard, but at this time, instead of black and white chess pieces, a layer of clear water flowed on it.

Under the flowing water, there are also chess pieces, but instead of playing chess normally, the chess pieces are arranged into a rectangle.

In the center of the rectangular pattern, there is a jade saucer, dangling.

Ye Rong counted, the chess pieces arranged in a rectangle were eight long and six wide, and in addition, the jade chessboard was empty.

"Throw in the correct number of pieces and start the game."

A low and mechanical electronic voice sounded in Ye Rong's ears, and with such an abrupt sentence, there was nothing else.

"Go, hint, you should give me a hint!"

This broken system suddenly jumped out of such a sentence without a head, and I don't know what Shengfeng's game designers are thinking in their heads, trying to make some bizarre questions to trick players, is this pure guessing numbers?

Ye Rong grabbed a handful of chess pieces from the cup on the edge of the jade chessboard, pinched them in his hand, and didn't know how many to throw.

Six, eight, rectangular......

After reading it twice, a few numbers lingered in front of Ye Rong's eyes, and his heart fluttered.

"It turned out to be so simple, but it was deviated before!"

Ye Rong counted ten chess pieces and threw them into the jade disc one by one, waiting for the changes in the chessboard.

Rectangles, 6 and 8, when these things are put together, the number 10 naturally jumps out - the square of 6 plus the square of 8 equals the square of 10; A rectangle with a length of 8, a width of 6, and a diagonal ratio of 10.

This is the simplest Pythagorean theorem, which can be thought of as long as you have the right idea.

Although Ye Rong had made a complete inference, he still looked at the chessboard nervously, after all, this was only his own inference, and it was not sure that it was the correct answer.

The chessboard shook, the clear water flowed, and the entire jade chessboard was actually moving in reverse, which made Ye Rong wave his fist excitedly.

According to the experience of beta players, in the Xianjia Cave Mansion, as long as there is a failure in one link, it will be teleported away immediately, and you will not even be given the opportunity to make amends.

The chessboard was completely reversed, revealing a long sword with cold light and a blue paper talisman.

Ye Rong took two steps forward excitedly, this is the reward of Langhuan Jade Cave, and he has already passed the test.

ps, the reunion is rounded, rolling and asking for recommendation votes!
