After a day of labor, Zhou Feng and the others followed the slave workers into a stone room, which was dark and damp and dimly lit. The inside of the stone chamber is also spacious, which can accommodate more than 100 people to lie down.

The slave laborers, tired and weak, lay on the ground in an orderly manner, stretching and relaxing their bodies. There were also some smaller slave laborers who laughed and played together, and did not worry about the current situation.

"It's time to eat!"

A few sturdy slave laborers brought a few baskets of radishes and put them at the door, and the slave laborers, who were physically and mentally exhausted, quickly got up and lined up to receive food. Zhou Feng and the others lined up at the back of the line, and each received two turnips.

The stone chamber was full of creaking, creaking sounds, like an animal farm. There was a teenage boy sitting next to Zhou Feng, the speed of eating radishes was called a fast, one radish in three or four bites, and in the blink of an eye, two radishes entered his stomach, and his face still had a feeling of unfinished.

Zhou Feng silently handed him a radish in his hand, and the boy bared his teeth at Zhou Feng, snatched the radish and wiped it out with only a few bites.

The others saw that Zhou Feng had a radish in his hand and gathered around, revealing begging eyes. Zhou Feng smiled helplessly, and broke the radish in his hand into several sections.

Zhi Ling, Mo Yan, Crazy Fire and others also learned from Zhou Feng to distribute the radishes to others, and this time the stone room began to be chaotic, and those who did not get the radishes began to coax the people who received the radishes. For a while, there were shouts, and some even scuffled with each other. Zhou Feng and the others were dumbfounded, for a turnip.

"Smack, smack......"

There was a sound of leather whips, and I saw more than a dozen strong slave laborers holding leather whips to disperse the chaotic crowd, and the stone room immediately fell silent.

"What's going on?" asked a strong man.

At this time, one of the slaves whispered in his ear and pointed at Zhou Feng and them with both hands.

The strong man strode forward with a whip, his eyes widened angrily, and he said viciously, "You guys are not hungry, are you?" ”

He raised his whip and tried to whip Xiong Hu, Xiong Hu's eyes glared, the guy swallowed a mouthful of spit, and whipped out.

"Smack!"

This whip was whipped on the shoulders of the thin monkey, and it was really a meteorite from the sky, and bad luck always fell on the thin monkey. The thin monkey's eyes were popping out, and he wanted to go up and bite the strong man to death.

"Heh! and glared at me. The strong man picked up his whip again and whipped it at the thin monkey.

"Smack!"

The head of the whip was grabbed by Xiong Hu, and with a slight force, the leather whip was snatched from the strong man's hand.

"What, you...... If you want to rebel, you can't do it. The strong man was shocked.

The other strong men rushed up one after another, and Xiong Hu broke the whip rod in his hand into two sections. These people were all stunned in place, this whip is made of black iron, this guy has too much strength!

"Brother, seeing that you are in good shape, you might as well join our security team. The strong man who was robbed of the leather whip by the bear tiger said with a smile.

The security team is to help the shaman manage slave labor and ensure the safety and order of the black kiln.

Hearing this, Zhou Feng hurriedly glanced at Xiong Hu, meaning to let him agree. Xiong Hu was not stupid, he thought for a while, and asked, "Do you have pasta to eat?"

"Yes, and meat. The strong man laughed.

The slave workers in the stone room heard that the flesh was all bright, and they were envious and jealous of Xiong Hu.

"There's meat! Okay, I'll go with you. Xiong Hu readily agreed to the invitation.

Working in the black kiln is divided into white nights, taking turns to work, and is allowed to rest twice a day, each time for three hours, and in the process of resting, each person is allocated two turnips, which is also the staple food of the whole day.

When it was time to work again, Zhou Feng and the others were led into a wide stone room, which was full of sacks one person high, and the smell of choking people flowed in the stone room.

Zhou Feng felt that this smell was very familiar, very similar to the smell of firecrackers when he was a child, could it be black medicine? Impossible, how could ancient humans have black medicine!

These sacks were transported by Zhou Feng and them to a stone chamber underground, and in one of the stone chambers, it seemed that someone was making something, so naturally they would not be allowed to enter. However, during the transportation process, Zhou Feng was able to conclude that this was black medicine from the black powder left on the sack.

Zhou Feng leaned against the stone wall and gnawed on the radish in his hand, puzzled by the black medicine that appeared here, what did the sorcerer do with these black medicines?

Mei Qinglin leaned next to Zhou Feng and nibbled on the radish, and said with praise: "It's delicious, I didn't expect the radish here to be so delicious." ”

At this time, Xiong Hu came in with a leather whip in one hand and a package in the other. He opened the package, and there were a few baked cakes inside. The thin monkey was quick-eyed, so he grabbed a big bite and ate it first, and several other people also picked up a baked cake and ate it with a radish. The room was full of people drooling, and with the experience of the past, Zhou Feng and they no longer dared to distribute food, so as not to cause a bigger snatching battle.

"To the west of the furnace there is an underground workshop where armor and weapons are being made, and huge pieces of black iron, I don't know what to do with them. Xiong Hu whispered.

"It seems that this is the underground forge of the wizards, and there is no special place, so if we find a way to destroy the furnace and workshop, our mission will be completed. Mo Yan said cautiously.

"Remember the sacks we carried this time, the black powder in them can burn, and it is very powerful. Let's get a few sacks out of the stone chamber and destroy their furnace mouth and workshop. Zhou Feng didn't say that this kind of thing was black medicine, for fear that they would think they were aliens.

"Are you sure those things will burn?" Mi Xiaoxi asked.

Zhou Feng nodded, his eyes full of determination.

"So this thing is made of flint? No wonder it smells. Mi Xiaoxi still said with some doubts.

"It doesn't matter what it is, with this thing we will save a lot of trouble, what should we do next?" Mo Yan looked at Zhou Feng as she spoke.

"My brothers and I went to destroy the furnace mouth, and my sisters went to destroy the workshop. Zhou Feng thought that the furnace was more dangerous than the bottom, so naturally it should be a man.

"Okay, that's it, let's go our separate ways. Mo Yan said.

In the dim passage, a huge black snake lay silently, lifeless, and next to it stood three black-robed wizards and several gray-robed men.

"Unexpectedly, even Da Hei couldn't stop them, what are these people, so good. A thin black-robed wizard said indignantly.

"I heard that the cultivators have already started to take action against us, I think it must be the master they have sent. A fatter black-robed wizard said thoughtfully.

"Then what are we waiting for here, hurry into the black kiln and catch them. A taller black-robed wizard next to him said.

Three black-robed wizards led several gray-robed men in quick pursuit of the passage.

Zhou Feng and the others gathered together again to discuss the time of action and the route of escape.

"Before we set fire to the sack, we must drive the slaves out first to avoid hurting people, and we must stay away from the sack when we light it, because the contents of it are very dangerous. After success, we went to the exit and escaped using the colorful gate. Zhou Feng explained the plan in detail.

At this time, Xiong Hu hurriedly ran over and said in a panic: "Oh no, there are three black-robed wizards and people who are searching for us." ”

"Then let's do it without further ado. Zhou Feng said hurriedly.

Zhou Feng took the lead in picking up four sacks of black medicine and rushed to the top of the furnace, and the three of them also picked up the black medicine and followed closely behind. A few gray shadows moved quickly along the winding mountain path, startling the slave workers who were transporting materials, these people are crazy, why are they running so fast!

The gray-robed men who were guarding saw the figure flash in front of them, as if they had thought of something, and felt loudly: "Catch them......"

The gray-robed people on the top of the furnace rushed down to intercept Zhou Feng and them, and the gray-robed people below the furnace also chased after them, forming a front and back attack. But how could they stop Zhou Feng, they were kicked out by Zhou Feng one by one like a ball. There was a great uproar on the furnace, and the slaves stopped transporting the materials and leaned aside to watch the bustle.

It didn't take long for Zhou Feng and the others to come to the top of the furnace, and more than fifty gray-robed people surrounded them with short swords in their hands.

Zhou Feng swept with one foot, and a blue light flashed, and suddenly five or six gray-robed people rushed to the end and lost consciousness. They also rushed into the crowd in the frenzy, and with one kick from you and one kick from me, they beat more than 50 people to the ground.

The three black-robed wizards who were searching for the infiltrator below saw the chaos on the furnace and knew nine times out of ten. They turned into black smoke and floated onto the top of the stove, turning the paper talisman into a fire cage and covering them around the wind.

"No, throw the sack over. Zhou Feng shouted loudly.

When several people heard this, they quickly threw the sack in their hands towards the black-robed wizard. These black-robed wizards knew the power of the black medicine in the sack, and they all collected the fire cage.

Zhou Feng signaled to them to retreat, and several people understood what Zhou Feng was going to do, and they used enough energy and mana to run down desperately, a puff of smoke when they came, and a light when they returned.

Before the three black-robed wizards could understand what was going on, a flash of fire from Zhou Feng had already hit the sack.

"Bang!"

The rockfall furnace cracked, and smoke and dust rose everywhere.

"Bang! bang......"

There were a few loud bangs, the entire black kiln trembled, the furnace mouth was blown up, and the magma poured down like a torrent, which Zhou Feng did not expect. The slaves and grey-robed men of the furnace fled in search of a place to take refuge.

Zhou Feng turned into a goldfinch and rushed down to the roof of the furnace before the explosion, and the three black-robed wizards also escaped with black smoke, but because their speed was a little slower, they were affected by the explosion and were seriously injured.

At this time, there were several explosions underground, and it seemed that Mo Yan and the others had also succeeded.

Taking advantage of the chaos, everyone quickly gathered at the northwest corner of the black kiln.
