Among the counties of the Northern Xuan Kingdom, Heishui County has the largest land area, but the population is the most sparse.

There is no precipitation and a lack of water for irrigation, so the fields have less food to feed them.

Blackwater County is famous for the Blackwater River, which, as the name suggests, flows with a strange kind of black water.

According to Xiong Meng and Gui Ye before, the black water in this river is highly poisonous, and every time there is thunder or lightning or hot weather, the river water will even burn an open fire, black smoke billowing, rain can not be extinguished, and those who inhale smoke and dust will die.

Meng Yun felt very strange when he heard about it, but in a blink of an eye, he understood that where was this black water, it was clearly crude oil.

It is common sense that oil is a black oily substance, which can be ignited, and if it is not burned sufficiently, it will produce toxic chemicals, and naturally cannot be used for irrigation.

By daybreak, the snow had stopped.

After a night's journey, the turtle master couldn't hold on, so he had to rest for a while.

Meng Yun took out the dry food and handed it to Er, this kid shook his head and didn't ask for it, don't pull it down and eat it yourself.

I found a tree and squatted against it, buried myself in gnawing on it, ate some snow when I was thirsty, and then continued to gnaw on the dough, which was frozen so hard that I could bite it and lose my big teeth.

While gnawing and watching the turtle master pour the black stone, Lao Wang Ba held the black stone and studied it all the way, but he didn't see any doorway.

Ten minutes later, he put away the dry food and walked over to the turtle master, "Can you see anything?"

"It's like it's alive and it's like it's dead," he muttered without raising his head.

"Give me what is dead or alive," Meng Yun snatched the stone.

No matter what the mystery of the stone is, the turtle master probably can't see the doorway in it, if he can see it, he will see it a long time ago, and he won't grind until now.

"What is this?" said the turtle master, turning his head to him.

"If I knew, I would still ask you?" Meng Yun put the black stone on the ground, took a step back and pulled out the Ice Xuan Sword, the turtle master saw this and hurriedly hid behind him, fools know what he was going to do, the last time the cave sword test left a shadow on it.

"Bang"

With a sword slash down, a large crater was blown out of the ground, but the black stone did not move.

On the scene, the earth and rocks were splashed, and Jie Xiu reacted quickly and ran away in advance, but he and the turtle master were poured with a dusty face and covered in mud.

Meng Yun collected the sword and flipped it to check, fortunately, there were no cracks in the sword body, and the Bing Xuan Sword was blessed with aura, and the tenacity should not be underestimated.

At the same time, the turtle master stepped forward to pick up the black stone, turned his head and pouted at him disdainfully, "There is no trace left." ”

"Hey, hell," Meng Yun put away his sword and reached out to take the stone, and then turned his head to look at Di Er not far away, "Uncle, let Er come over and try it." ”

Immediately after, he didn't know what the turtle master said to Er, this guy directly appeared the black dragon body, a behemoth ten zhang long.

The black dragon jumped into the sky, hanging two feet above the ground, exuding a terrifying aura, as if the surrounding aura was trembling, majestic and domineering.

He hadn't seen the body of the dragon since the last time, but after seeing it this time, he couldn't help but be shocked to find that the black dragon's body was two times larger than the last time, and its body length was almost three times that of the past.

The long dragon whiskers, the dark dragon scales, the hideous dragon head, and the dragon claws have also turned into five claws, thick and powerful.

The two placed the stone on the ground, retreated a hundred paces, and watched from afar.

Er's cultivation is between man and God, and it is not comparable to a half-person like him at all, if he does it with all his might, if he is not careful, he will be affected and the game will be over.

After the two of them stood still, the black dragon immediately began to gather momentum, and the huge metal aura between heaven and earth frantically surged towards the dragon claw.

In an instant, the dragon's claws emitted heart-palpitating fluctuations.

The man in the black cloak gave him the feeling of being like a black hole, and he was like a compressed sun at the moment, one restrained and weirdly profound, the other depressed and ready to explode at any time.

A few seconds later, the black dragon quickly gathered momentum, and with a dazzling white light, it raised its claws and smashed it towards the ground.

"Boom"

There was only a muffled sound in my ears, and the whole ground was shaking, but this was not the most terrifying, with a transverse wave rippling, after the dust settled, with the claw hitting the black stone as the center, within a radius of a hundred steps, the ground fell as much as two feet.

Just when he was shocked, the black dragon re-landed and transformed into a human body, picked up the intact black stone, and came to him in a flash, shaking his head helplessly.

"Uncle, what is this? It's so hard," Master Turtle took the black stone.

Pulled back by the voice of the turtle master, he looked down at the black stone again, it is indeed the extreme evil gate, but if it can't be opened, I'm afraid no one can open it, and I'm afraid the secret will be unknown.

"Where the hell did you get it, boy?" said Master Turtle and returned the black stone to him.

"Someone gave it to me," Meng Yun reached out and took the stone, and the man in the black cloak said that the black stone was his, what was the secret in it?

"Who, when?" asked the turtle master.

Under the questioning of the turtle master, he summarized what happened last night, of course, he didn't mention those shocking pictures, he mainly talked about the black cloaked man, and his terrifying cultivation.

Five minutes later, the turtle master scratched his head and said, "What does it look like?"

"I didn't see it, I said he was wearing a black cloak," Meng Yun said.

"How could you provoke such a character?" the turtle master looked at him with some suspicion.

"Uncle, how did you hear it, why did I provoke him, obviously he found me for some reason," Meng Yun glared at the turtle master angrily.

After finishing speaking, he remembered the scene again, "When I went back, you didn't sense the aura fluctuations?"

"No," the turtle shook his head.

"Where?" he looked at him again.

At this moment, Er Wenyan looked at the turtle master again, and then shook his head at him.

By this time, he felt more and more the horror of the black cloaked man, and with his aura cultivation, he didn't even notice the appearance of the other party.

Seeing him fall silent, "What are you going to do?"

"I don't know, my mind is all mush now," Meng Yun shook his head and said, this thing is too unbelievable, the black cloak is a mysterious existence, and the words that the other party said pulled him into the unknown and lost.

The scene depicted on the parchment scroll seems to have gradually emerged, the war of the Terrans has begun, what if he can't go back? Do you really want to join this melee? With his weak cultivation, what role can he play in the battle?

"Let's go to the county town and find what Old Man Qi left for you," Master Gui thought about it and said again.

......

On the road leading to the county seat, almost all the villages along the way were slaughtered, and none of them were spared.

Most of the dead died in the same state, turning into a dried corpse, according to the turtle master, the villagers were sucked dry blood and souls and died, very vicious and cruel.

War is very cruel, and the overwhelming side of the forces wantonly destroys the defeated side, whether it is men, women, children, old, weak, sick and disabled.

......

The next day, in the morning, the sky was a little overcast.

An ancient city appears in front of you, the city is built on the mountain, stretching for seven or eight miles from east to west, the city wall is more than six meters high, the wall seems to be made of green bricks, and there are many battlements on it.

There are three gates in the city, which are the east and west south gates, and the one in front of you is the south gate.

There are marks of fire on the gates, and there are signs of siege under the walls, so it is judged that there have been battles recently.

As they approached, a sergeant in bronze armor poked his head out of the battlement in the gate, "Who are you?

"Refugees from the north, please go into the city to escape the scourge of war," Meng Yun raised his head and shouted at the city gate guard, he had already thought of the whole set of words, and naturally there was nothing to hesitate to answer.

"No, the county keeper has an order, and in order to prevent the barbarians from being spies, no one is allowed to enter the city," shouted the gate guard again.

Meng Yun frowned when he heard this, Xiong Meng was really right, this county guard is guarding the city, regardless of thirty-seven twenty-one, no one is allowed to enter the city.

There are probably two reasons for the other party to do this, either they have no experience in defending the city and are timid, or they have been mixed in by the enemy and suffered losses.

"Get your wizard here," the wizard can sense the aura fluctuations, and when the time comes, let the wizard release some aura, so that the wizard guarding the city can know that they are different from ordinary people.

But after shouting, he regretted it a little, unlike his concept, in the eyes of the other party, the status of the wizard is very high, and it is impossible to really call the wizard over for him.

Sure enough, after he said this, the city gate guard immediately showed a look of disdain, "Hmph, Lord Wizard, how can you ......?"

At that moment, another voice rang out from the city gate, "Which wizard are you looking for?"

"Childe," the gate guard took two steps back and saluted with fists in his fist.

The person who came was no more than thirty years old, and between the gestures, there was a bit of ancient Confucian temperament, different from the shabby copper armor worn by the guard, the other party was wearing leather armor, black shiny, clean and tidy.

"Looking for the Wizard of Qi," Meng Yun hesitated for a moment and reported the name of the Wizard of Qi.

The county town of Blackwater County is very small, and there won't be too many great witches to guard it, if the wizard really came, it is impossible that no one will know, unless he hasn't come, but the black cloaked man should not fool him.

"Oh, who are you Wizards?" the other man looked surprised.

"We are ......"

At that moment, a trumpet sounded from the city gate, "Woo-"

Immediately after, a sergeant hurriedly ran to report, "Bao Gongzi, twenty miles away, a large number of barbarian wolf horses are coming!"

"Hmph, it's coming so fast," the other party waved at the sergeant to sign back, and then turned to him and said, "Little brother, I'm sorry, let's run for your life-"

On the surface, he said that he couldn't help it, but the other party spoke inadvertently, but there was despair in his eyes, and this reaction undoubtedly showed that the city could not be defended.

"Let me in, we can help you defend the city, put a rope down," Meng Yun shouted again at the head of the city, he was coming for the county town, how could he turn around and leave.

If it weren't for the fact that he couldn't fly with people, he would have already boarded the city gate, and he still needed to pull around here.

"Childe, don't talk nonsense with him, go into the gatehouse for a while," the city gate guard urged the man, and the two guards also stretched out their hands to stop him, which can be seen that this young man's identity is not ordinary, otherwise, he would not be so closely protected.

"This," seeing his firm tone, the other party first muttered a little, and then turned to the city gate guard and said, "Pull him up!"

"Childe!" the gate guard ignored him.

"Do as I say!" the other man's tone became serious.

"Yes," the gatekeeper clenched his fists......
