The breeze was gentle, and the prairie was unusually quiet.

Bubutni was running on the grassland with Su Xiao on his back, and he had been walking for nearly two hours.

"Bubu, stop."

Su Xiao looked around, and everywhere he saw was verdant, and he could vaguely see the trees before, but now only the grassland remained.

"What's wrong?"

The little emperor who took the hanging ticket opened his mouth and asked, except for Su Xiao, other people dared to ride on Bubutni's back, and these two goods turned around, so the little emperor is now taking the 'hanging ticket', and he is being carried by Su Xiao with one hand.

"There's something wrong here."

"Dangerous creatures?"

"No, we might be lost."

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

"How can we get lost, aren't we always moving forward?"

The little emperor looked around, and the scene was about the same everywhere he looked, an endless verdant grassland.

"Boo, run forward."

Su Xiao stood in place and let Bubutni move forward in a straight line.

Bubutney was normal when he ran more than 10 meters away, but after running 100 meters, the course began to deviate.

You must know that Bubutni will turn back from time to time to determine Su Xiao's position, and try his best to keep a straight line with Su Xiao.

After Bubutni ran out of a few hundred meters, Su Xiao could only vaguely see the other party, and something even more strange happened, Bubutney actually ran out of a semicircle, came to Su Xiao's rear after making a circle on the grassland, and a few minutes later Bubutney and Su Xiao rounded.

They kept going around in circles, but Su Xiao was helpless.

There were no markers on the grassland before, but after he served as a marker, Bubutney was still going around in circles.

It's a bit tricky, and it's supposed to confuse the creature's sense of direction.

Su Xiao thought in place, 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 go around in circles.

He couldn't decipher the arrangement quickly unless his perception covered the entire grassland, but it was clearly impossible.

Since you can't tell the opposite, you simply don't know the direction to move forward.

It's just a sense of direction, not a maze, and there's an essential difference between the two.

Riding on Bubutni, Su Xiao began to direct Bubutni to run forward.

Now he spared two large circles to the left, and then circled a few times to the right, during which Su Xiao inserted an iron drill on the ground from time to time.

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

There are a few iron drills that are kept in a straight line, while others are inserted haphazardly in the grass.

"Bubu, go on."

Su Xiao took out a pen and paper in the savings space, first drew a circle on the paper, and then used the pen to point out some black dots on the paper.

The circle began again and again, and after sparing about dozens of laps, Bubutni couldn't stand it, and the two goods also noticed that they were going around in circles.

"The first thirty meters, the left fifty meters, the right ten meters, no, the right fifteen meters......"

Su Xiao racked his brains to find the right route, although his face was calm, his heart had already 'greeted' the designer of this grassland countless times.

The designer is a perfectionist, and the number of steps is different every time he changes direction, which makes it even more difficult to calculate.

"Bubu, thirty meters ahead."

Bubutni turned his head to look at Su Xiao, his face was full of confusion, as if he was asking, 'Boss, how far is thirty meters?' ’

Su Xiao sighed secretly, he overestimated Bubutni's IQ a little, Bubutni is an intelligent creature, but his IQ is a little touching, commonly known as the second goods.

"It's okay to walk forward, stop immediately when I shout stop, and I can't take more than one step."

Bubutney began to walk forward, sometimes to the left, sometimes to the right, and occasionally a few steps back.

"In this direction, keep running."

Bubutni ran wildly, and the scene in his sight changed, no longer a grassland.

Succeeded, he used his IQ to get out of that grassland.

The surrounding scene is finally no longer the same, and some low trees appear in view.

[You have entered the heart of the 'Birumak Alchemy Proving Ground', and the alchemy toxin has changed. 】

[You are being eroded by the 'Strolo' alchemy toxin, -10 strength, -10 agility, -10 stamina, and take 7 true damage per second.] 】

[Whether to turn on the advanced air filtration device or not, it costs 300 Paradise Coins per hour.] 】

A feeling of weakness appeared, and Su Xiao felt that his entire body began to feel heavy.

"On."

Although my heart hurts, I now have to use the air filtration device of Samsara Park.

Half an hour later, the surrounding grassland was no longer vast, two stone walls appeared, and the forward route was a funnel-shaped, narrower and narrower.

At the end, a cave dozens of meters high appeared in front of me, and all the plants on the ground near it were yellowed and withered.

A strong smell of burnt paste came, and Su Xiao commanded Bubutney to walk into the cave.

Not long after entering the cave, a heavy footstep came from behind, and Bubutney hurried into the gap in the rock wall beside him.

"Gabaha cough...... (Unknown Language). ”

"Tutu tweets...... (Unknown Language). ”

This should be a language, Su Xiao couldn't understand a word, he hid in the crack of the rock wall, and looked out.

A group of strange creatures with a height of only about one meter, thin bodies, dark yellow skin, protruding eyes, and pointed ears, all appeared in human form.

There are five strange creatures in total, although they are only about one meter tall, but their strength is not small, each strange creature holds an iron box more than three meters high, and the iron box contains a kind of black and shiny stone.

Su Xiao immediately recognized that it was coal, this creature was most likely an intelligent creature, could this be an alchemist? This look is also too sorry for the audience.

"This seems to be a dangerous species: the Cryptmen, but the Cryptmen don't have that much strength."

The little emperor recognizes the origin of the strange creature.

"Cryptmen? A human kind? ”

"No, the cavemen are between humans and beasts, they have an independent language, they generally live on the west side of the continent, there are about hundreds of thousands, they often raid nearby villages, they also have the habit of eating people, to be exact, as long as they are living things, they will eat, if they are too hungry, the weak kind are also emergency food."

The little emperor knows a lot about dangerous species.

While the two were talking, the cavemen had already entered the cave.

Su Xiao was very concerned about the destination of those cavemen, and he began to follow several cavemen, and Bubutny and the little emperor followed behind Su Xiao.

Several cavemen were familiar with the terrain of the cave, and after about ten minutes of turning and turning, several cavemen entered a clearing.

Thundered.

The sound of large machinery coming from the clearing, Su Xiao saw it in the clearing.

It is an open space of thousands of square meters, and the open space is filled with large machinery.

These large machines are all made of steel, to which some metal conduit is attached, and the other end is deep into the rock face.

In the center of the clearing, a furnace more than ten meters high was working, and all the coal transported by the cavemen was thrown into the furnace.

The temperature in the clearing was high, and there were hundreds of cavemen at work around the large machinery, their shirtless bodies covered in beads of sweat and their dark yellow skin covered in dirt.

Syllable!

There was a crack of whips, and several taller cryptmen were standing on the steel machine, long whips in their hands, supervising the work of the cryptmen below.

These cavemen who looked like they were about 1.5 meters long, wearing rudimentary armor, pale blue skin, and their big eyes were extremely ferocious.

Hearing the sound of the whip, the coolies of the crypt people below shook their bodies, and they worked harder to carry coal, maintain machinery, etc.
