The gentle breeze makes the grassland very quiet.

Bustani, carrying Su Xiao, has been running on the grassland for nearly two hours.

"Bub, stop."

Su Xiao looked around. The place where he saw it was green. He could see trees before. Now there is only grassland.

"What's the matter?"

The little emperor, who was riding on the ticket, asked, "except Su Xiao, others dare to ride on the back of bubteni. These two goods turn around. So the little emperor is now riding on the" ticket hanging "and is being carried by Su Xiaodan.".

"There's something wrong here."

"Dangerous creatures?"

"No, we may be lost."

Su Xiao jumped off buxtney's back and pulled out an iron chisel in the grass not far away, which he had inserted here before.

"How can we get lost, not all the way forward? "

when the little emperor looked around, the scene was almost the same, the endless green grassland.

"Bub, run forward."

Su Xiao stood where he was, and let bouttney go straight.

It's normal for bouttney to run more than ten meters, but the route starts to shift after running more than one hundred meters.

You know, from time to time, bustani will turn around to determine Suxiao's position and try to keep a straight line with Suxiao.

After a few hundred meters, Su Xiao could only vaguely see each other. Even more strange things happened. However, he ran out of a half circle on the grassland and then went to the rear of Su Xiao. A few minutes later, he had a round with Su Xiao.

They have been turning around, but Su Xiao is helpless.

Before, there was no sign on the grassland, but after he acted as a sign, bouttney still went around in circles.

It's a bit difficult. It should be able to confuse the sense of direction of creatures.

Su Xiao thought in situ. This grassland will confuse people's sense of direction. It should be the visual deviation effect caused by the surrounding environment. The more you want to walk in a straight line, the more you will circle.

He couldn't decipher the arrangement quickly unless his perception covered the whole grassland, which was obviously impossible.

Since you can't tell the opposite direction, you can't go in the right direction at all.

It's just to confuse the sense of direction, not the maze. There's a fundamental difference between the two.

Riding on the butney, Su Xiao begins to command the butney to run forward.

Now he has made two large circles to the left and several to the right. During this time, Su Xiao inserts a steel drill in the ground from time to time.

After a dozen laps, Su Xiao began to check the dozens of iron chisels on the ground.

Some of the bits are in a straight line, while others are stuck in the grass.

"Cloth, go on. "

Su Xiao takes out the pen and paper in the saving space, draws a circle on the paper first, and then points out some black spots on the paper with the pen.

At the beginning of the circle, after about dozens of circles, bubteni could not bear it. The two goods also noticed that they were circling.

"The first 30 meters, the left 50 meters, the right 10 meters, no, the right 15 meters..."

Su Xiao racked his brains to find the right way. Although his face was calm, he had asked the grassland designer "hello" from his heart many times.

The designer is a perfectionist. The steps of changing direction are different every time, which is more difficult to calculate.

"Cloth, 30 meters earlier."

Butney turned to look at Su Xiao. The dog's face was blankly, and he seemed to ask: "boss, how far is thirty meters."

Su Xiao sighs secretly. He overestimates the intelligence quotient of buteni. Buteni is an intelligent creature, but his intelligence quotient is moving, which is commonly known as the second best.

"Just go ahead. I'll stop as soon as I stop. I can't go any more."

Bouttney began to move forward, sometimes to the left, sometimes to the right, and sometimes to step back.

"This way, keep running."

The scene in bubteni's vision changes as he rushes. It's no longer a prairie.

Successful. He walked out of the grassland with his IQ.

At last, the scene is not the same. Some low trees appear in the sight.

[you have entered the center of the "birumak alchemy proving ground" and alchemical toxins have changed. ]

[you are being eroded by 'sderolo' alchemy toxin, strength-10, agility-10, physical strength-10, receiving 7 real damage per second. ]

[whether to turn on the advanced air filter device requires 300 yuan per hour. ]

weakness appeared, and Su Xiao felt that the whole body began to be heavy.

"On."

Although my heart is aching, I have to use the air filter of reincarnation park now.

Half an hour later, the surrounding grassland is no longer broad, two stone walls appear, and the route forward is a funnel-shaped, narrower and narrower.

At the end of the day, a cave tens of meters high appeared in front of it. All the plants on the ground nearby were yellow and withered.

There was a strong smell of scorching, and Su Xiao directed bubbney into the cave.

Shortly after entering the cave, a heavy footsteps came from behind, and bubbney hurried into the crack in the rock wall.

"Gabach cough (unknown language). "

"Tutujo (unknown language). "

It should be a language. Su Xiao can't understand a word. He hides in the crevice of the rock wall and looks out.

A group of strange creatures with a height of only about one meter, a thin body, dark yellow skin, protruding eyes, sharp ears, and a whole human shape appeared.

There are five strange creatures in total. Although they are only about one meter high, their strength is not small. Each strange creature holds an iron box more than three meters high, which is filled with a kind of black and bright stone.

Su Xiao immediately recognized that it was coal. This creature is likely to be intelligent. Is this the alchemist? I'm sorry for the look.

"It seems to be a dangerous species: cave people, but they don't have such great strength. "

the little emperor recognized the origin of strange creatures.

"Cave man? A kind of human? "

"No, cavemen are between human beings and wild animals. They have independent languages. They usually live in the west side of the continent. There are hundreds of thousands of them. They often plunder nearby villages. They also have the habit of eating people. To be exact, as long as they are living creatures, they will eat. If they are too hungry, the weak and small ones are also emergency food."

The little emperor knew a lot about dangerous species.

During the conversation, the cavemen had entered the cave.

Su Xiao was very concerned about the destination of the cave people. He began to follow the cave people. Bubuteni and the little emperor followed Su Xiao.

Several cavers are familiar with the terrain of the cave. About ten minutes ahead of the seven turns and eight turns, several cavers enter an open space.

Boom.

The sound of large machinery was heard in the open space, and Su Xiao saw it in the open space.

This is an open space of thousands of square meters, full of large machinery.

These large machines are made of steel. Some metal conduits are connected to these machines, and the other end is deep into the rock wall.

In the center of the open space, a ten meter high furnace is working, and all the coal transported by the cave people is put into the furnace.

The temperature of the open space is very high. There are hundreds of cave people working around those large machines. Their red upper body is covered with sweat beads of oil, and their dark yellow skin is covered with dirt.

PA!

A whips of the crisp sound came, there are several tall cave people standing on the steel machinery, hand whips under the supervision of the cave people work.

These cavemen, who look like guards, are about one and a half meters old. They are dressed in simple armor and have pale blue skin. Their big eyes are extremely fierce.

Hear whips, the underground cave people coolie body a shake, more efforts to carry coal, maintenance machinery, etc.
