After all the poisonous vines rotted and turned into dirt, the full extent of the stele was revealed.

The stele is roughly rectangular, slightly inclined to the left, the amplitude is not large, a red stepping stone is pressed under the inclined end, Bo Yituo squatted down to try, pressed very tightly, there is no way to pull it out by strength.

From the side, the shape of this stele is very special, like a small top and large bottom of the 'paper bag', the top of the 'paper bag' is tightly sealed, and a lot of weeds grow at the tip.

Bo Yituo was very strange about this, and he asked Zimu Hitomi: "Little Hitomi, how can grass grow on the stones?

"The fact that grass grows on the stone proves that there must be a gap in the middle of the stone, or something hidden. You look at the surface first, are there any special patterns and words? Hitomi's baby body is too restrictive for me to learn more. ”

"Good. ”

Zheng Zhan and Bo Yituo immediately went around to the back of the stele to look, because the front of the stele was empty and there was nothing!

"There are five rows of small holes in the back, six in each row, and there is no text or pattern. However, the inside of these holes seems to be clean, without a trace of dirt and weeds. Zheng Zhan put his finger in and tried it, and after taking it out, there was not even dust on his fingers!

He told all this to Hitomi Purple Mu, who fell into deep thought: there are impurities in the small hole, which proves that someone uses it regularly. According to Zheng Zhan and Bo Yituo's descriptions, these small holes are about chest level.

The diameter is about a finger or so, and then there are soft things inside to the touch, which can be pushed inward, and it should be a small enchantment made of some spiritual mana or the juvenile body of a small monster is also possible.

Due to the limitations, what is inside can only be pushed inward, and it is simply impossible to pull it outward. If you put your eyes up to see it, you can't see anything clearly.

"Where is the red brick stuck underneath?" Hitomi Shigi asked suddenly.

Bo Yituo immediately replied: "It's stuck under the bottom corner of the left, and the stele is tilted to the left." ”

"Bo Yituo, you and Zheng Zhan are now working together, you count the third small hole in the first row from right to left, the second small hole in the third row from right to left, and the first small hole on the right side of the fifth row at the same time, remember to push the things inside to the bottom!"

"Zheng Zhan, you count the second hole in the first row from left to right, the second hole in the second row from left to right, and plug the first hole on the left side of the fourth row at the same time, the same method as Bo Yituo. Then you kick the red brick down there hard and see if it can be kicked out!"

"Okay!" Bo Yituo and Zheng Zhan responded at the same time.

"Two people have to act together, or they won't work. Hitomi Shigi added.

Everything that followed was according to what Zimu Hitomi said, after the two elf boys pushed the contents of the small hole to the end at the same time, the red bricks that had been suppressed just now suddenly loosened at this moment, and the thin wing Tuo, who was close to him, immediately kicked hard, and the red bricks immediately flew several meters away, and half of them were inserted into the grass.

After letting go of his hand, Thin Wing Tuo flapped his wings and quickly picked up the red bricks that had been beaten into thin pieces.

He took it in his hand and looked left and right, but there were no words and patterns on it, Bo Yituo couldn't help but be a little discouraged, after handing over the bricks to Zheng Zhan, Bo Yituo asked: "There is no code on it, what should I do?"

Zimu Hitomi's answer immediately came out: "It's not a code, this is a key, you insert it into the gap at the top of the stele, and you can open the stele." ”

"But I still don't understand why, how did you know that the red bricks are the key?" Bo Yituo continued to ask, he really couldn't understand what Hitomi Zimu thought?

Zimu Hitomi said: "You open the stele first to see what is inside, and then I will explain to you when you pass here, it is important to save your brother." ”

"Okay, I'll go!" Bo Yituo agreed, and immediately approached the stone monument and began to act.
