Qingduan Chen and the others traced their way up the underground river and began to enter an underground cave system, all the way to the west, all the way through the natural passage formed by narrow underground fissures.

The cave passage is pitch black, full of forks and torrents, many places have to dive into the water, the longest section of the underwater passage is as long as a hundred miles, if it is not for the bluestone has understood the water of the heavenly way, can sense and identify the passage and the dead end, I am afraid that they will have to spend a lot of time.

In addition to the underground river, along the way passed through dozens of large underground caves and lakes, encountered a lot of river Jiao, cave crocodiles and other evil beasts, the three of them walked for more than a month, at least two thousand miles, before walking out of an underground cave and returning to the ground.

Above the ground is a large limestone hill, the bare stone mountain is almost devoid of grass, and the aura and air are as thin as the desert.

Qingshi took out the map of the Shenmu Continent given by Daddy Bai, and after the three of them calculated, they found that they had come to the hinterland of the continent, and from here they could reach Baiyun City by walking two thousand miles north.

Ten days later, outside Beigu City, about 100 miles south of Baiyun City, there were three human monks wearing strong suits inside, hooded cloaks, bows and arrows, and swords, these were Qingshi, Duan Wutian, and Chen Tianye.

Beigu City is the northernmost large city under the rule of the Ten Thousand Immortals League, and it directly confronts the last city of the human resistance army, Baiyun City, and is the most important military fortress to prevent the human resistance army from moving south and entering the area ruled by the Ten Thousand Immortals League.

To the north of Baiyun City is the Great Snow Mountain, a bitter cold land, with no life at all, to the west is also a barren lofty mountain, and to the east is a large desert full of quicksand, so the Ten Thousand Immortals Alliance only needs to block the south to trap the human resistance forces in Baiyun City. And the most important city and stronghold of the southern defense line is this Beigu City.

Beigu City has been operated by the Ten Thousand Immortal League for hundreds of years, the city walls are tall and strong, and the defensive magic array is dense, and at the same time, the entire city has also set up a giant spirit gathering array, making the spiritual energy in the city several times more abundant than the outside world.

There are 3,000 'immortal soldiers' stationed here, and the immortal soldiers are an army composed of shape-shifting demons, known as the 'Xianqu Army', of course, most of them are 'quick demons'.

There are more than 20,000 human alliance troops serving the Ten Thousand Immortals Alliance, and there are 100,000 spirit beast armies distributed in the barren mountains and canyons outside the city. In order to ensure the normal operation of these military forces, there are thousands of 'great immortals' and hundreds of thousands of human beings living in the city, engaged in various related jobs and livelihoods.

In a hundred years, Beigucheng has gradually developed from a single military fortress to a large city dominated by military, because whether it is the 'immortal soldiers' or the human alliance army serving the Ten Thousand Immortal Alliance, they have various needs.

Therefore, the smelting, casting, transportation, textile, catering, entertainment and other industries that serve the military have gradually developed, and today, it has already been a thriving scene.

There are only two gates in Beigu City, the north gate has been closed for many years, only the south gate will open and close regularly every day, when the three of Qingduan Chen walked outside the south gate, the human beings and 'great immortals' who were waiting outside the door to enter the city were already thousands. They could only blend in with the crowd and wait for the door to open.

Soon, the wide city gate slowly opened, and I saw that the city gate was divided into five passages of different sizes by the fence, two passages for people and chariots and horses to go out of the city, and two passages for people and chariots and horses to enter the city.

The 'Great Immortals' all go through a special passage to enter and exit, and their number is very small, although there are 'immortal soldiers' standing guard, but they are not checked.

There were a lot of people entering the city, and when it was Qingshi's turn to be the same, they still used the identities of Haiya, Mangju and Kesuyun, and learned the answers of the previous people, saying that the three of them came to join the army and wanted to join the human 'Co-Glory Army'. The interrogating sergeant only glanced at them and let them go.

Entering the city, Qingshi and the others did not really go to the 'Gongrong Army' battalion headquarters in the west of the city as instructed, but came to the business district in the east of the city and lived in an inn that was neither luxurious nor shabby.

It is not an easy thing to get out of Beigu City and go north and enter Baiyun City, which has been blocked for a hundred years. Because, the entire northern defense line has been laid by both sides, and it is impossible for a person, not even a bird, to cross these lines.

Qingduan Chen and the others are not in a hurry, since there is no good way, let's wait for the opportunity. There are many restaurants and restaurants in this Beigu City, and there are many entertainment venues, and the three of them hang out every day and enjoy the exotic customs, which is not boring.

On this day, at dusk, Qingshi walked out of the door after nine weeks of Dahuang Gong, Chen Tianye had been waiting for him for a long time, and when he saw him come out, he immediately pulled him to go to the 'Spring Rain Building' to drink and listen to music.

Qingshi never sleeps in flowers and willows, Chen Tianye naturally knows. However, he said that he went to listen to the music today, the top singer of the Spring Rain Building, 'Yingying', does not sell her body, and singing the song is the first in the world, Chen Tianye went once, and greatly appreciated it, so he spent a lot of money to get his reception alone tonight. Aoshi agreed.

Chen Tianye called Duan Wutian again, and the three of them came to the Spring Rain Building in a hurry, who knew that when the waiter saw them, he hurriedly waved his hand to let them go, saying that there was another distinguished guest today.

"What?" Chen Tianye said angrily, "Lao Tzu paid the deposit three days ago, and said that he would listen to Miss Yingying sing tonight, don't you recognize Lao Tzu?" Tell your boss lady to come out! ”

"It's not a reckless boy!" The waiter said with a sad face, "Xiao naturally remembers your old man, and I also know that you have made an appointment for the Yingying girl's brand tonight, but the sixth general of the 'Xianqu Army', Delang Daxian, is here, so ......"

"How can it be!" Chen Tianye said, "Since you have agreed to Lao Tzu's reservation, then you have to do it!" Why did you let someone else get ahead of the curve? ”

The waiter was so sorry, and called the proprietress again, the proprietress saw Chen Tianye, and explained again, Chen Tianye came a few times, and he was generous, and the proprietress naturally did not want to offend, but today's situation was special, but she had to miss the appointment, and immediately took out the deposit and returned it to Chen Tianye.

Qingshi didn't want to be entangled in such a thing, smiled slightly, patted Chen Tianye's shoulder and signaled to leave.

Chen Tianye was helpless, so he had to say: "Okay, then this son will come back tomorrow night!" You should keep this deposit. ”

"This ......," the proprietress was embarrassed, "Mangju Gongzi, you better take it back, my Yingying girl is afraid that she will not be blessed to sing music for her son in the future." ”

Chen Tianye was shocked, and hurriedly asked why, and the proprietress explained the situation. It turns out that since Miss Yingying started to pick up customers three years ago, she has always shown that she is not selling her body, she has excellent singing skills, and she doesn't look very good-looking, so the high-roller bosses in Beigucheng have also fulfilled her, and they have not forced her to sleep.

However, three months ago, after the sixth general of the 'Xianqu Army', Delang Daxian, saw the Yingying girl, he insisted on possessing her.

Miss Yingying was unwilling, and this Delang was entangled several times, and today he came again while he was drunk, threatening to sleep with her today, and take her home tomorrow to be a mother-in-law.

Now, the warbler girl is singing to him, hoping to stabilize him, but this Delang is very powerful, and the force is high, and he acts arrogantly and unscrupulously, and the proprietress estimates that the warbler girl is afraid that she will be in a catastrophe today.

Qingshi originally didn't want to pay attention to this matter, but when he heard the proprietress say this, he couldn't help but secretly scold this Delang for being really a beast.

Get rid of him! Bluestone made a decision immediately.

Qingshi was about to think of a way, when he suddenly heard a woman's scream from the backyard, and at the same time, a beastly laugh sounded: "Hahaha...... This great immortal has taken a fancy to you, that is your blessing...... What are you hiding, haha......"

The proprietress sighed and shook her head, and the three of Qingduan Chen knew that this Delang Daxian was going to overlord the bow. At this time, Qingshi was not allowed to think of a way, the three of them glanced at each other, their hearts were connected, Chen Tianye led the way, Qingshi and Duan Wutian followed, and the three of them rushed to the small courtyard of the Yingying girl together.

"Ouch! Don't go! ”

The proprietress and the three waiters ran over together, trying to stop the three of Qingduan Chen. As a result, as soon as he entered the small courtyard, Qingshi turned around and knocked the four of them to the ground one by one, and then closed the courtyard door.

This single courtyard is not big, only a delicate two-story building, at this time, on the second floor of the Yingying girl's guest room, Delang deliberately let himself get drunk, he is not in a hurry to do things, is laughing while staggering around, tearing off a wisp of Yingying's clothes or half of the skirt from time to time, causing Yingying to scream in fright, wanting to capture and indulge, enjoy it.

Suddenly, a brick broke through the window, smashing several bottles and cans, and making the ground shattered with broken porcelain tiles.

"Delang, you pig and dog are not as good as bastard!" Qingshi stood in the courtyard and scolded, "Get out of here!" ”

"Who?" Derang was furious and roared, "Who the is impatient enough to meddle with grandpa's business?" ”

"The girl that Ben Daxian has a crush on," Qingshi continued to scold, "You fucking dare to force it!" Hurry up and get out and try it with Lao Tzu, I'll give it to you if you can beat Lao Tzu, if you can't beat it, go back to your beast circle quickly! ”

"Grandpa is here!" Derang slammed the door and shouted, "I'm going to see who's impatient!" ”

Delang rushed out of the room, only to see a person standing in the courtyard shouting and scolding, and immediately jumped down and punched this person.

As soon as Qingshi saw Delang, Qingshi's mind moved and released the puppet Yanlong, and at the same time activated the stealth function of Xuanyuan Jia to hide the trace, in fact, he did not move his position, but used the art of earth escape to sneak underground. After comprehending the Heavenly Dao of the Earth, the bluestone escaped into the soil as if it were diving into the water.

Delang punched, and a ten-zhang long Yan Dragon appeared in front of him, grabbing him with a claw. Delang was taken aback, stretched out his arms to separate his claws, and shook violently into a monster about the size of the Yan Dragon, which turned out to be a Kui Niu.

It's good that Kui Niu doesn't turn into his original form, and as soon as he turns into his original form, he immediately finds that he is tightly entangled in his body by dozens of energy ropes, it turns out that there is a trapped array in the small courtyard by bluestone, and the scope of the trapped array is only a little larger.

Delang sensed that something was wrong, and immediately mustered up all his strength to directly burst the trapped array, but Yanlong was not within the scope of the trapped array, it hit Kui Niu hard, Kui Niu couldn't dodge, so he had to resist, Yan Long's steel claws fell on Kui Niu's head, making a muffled sound.

The Kui Ox's skin was so tough that the puppet dragon couldn't scratch it, but the claw struck the puppet's head firmly, making it dizzy and buzzing in its head.

Kui Niu roared violently, and used all his strength to try to break the shackles of the magic circle, and at the same time crashed into the puppet Yan Long, Yan Long stretched out two front paws against the two horns of the Kui Niu, and the tail supported the feet to resist, however, this Kui Niu is not a 'quick demon', but a real big demon, the power of the puppet Yan Long couldn't bear him, and he was pushed back again and again.

At this moment, Duan Wutian, who was hiding in a corner of the courtyard, jumped up a few zhang high, picked up the sky-breaking axe and slashed down at the bull's head, Kui Niu saw that the situation was not good, turned his head and turned the horns of the cow towards the sky-breaking axe, when there was a crisp sound of metal strike, Duan Wutian's axe flew out of his hand, and he himself flew back a few feet away, his hands were painful and numb, and he trembled.

After Duan Wutian broke through to the Immortal Pill Realm, his combat power was almost invincible under the Shenyuan Realm, but in front of this real transformation demon, it was still not enough. Although this Kui Niu Delang is not as far as Aso Kun, its combat power is also quite terrifying.

Whoosh, a golden arrow suddenly shot in front of Kui Niu's right eye, Kui Niu didn't expect a sneak attack, too late to dodge, quickly closed his eyes, the golden arrow shot on its eyelids, although it pierced the cowhide, but also failed to blind its eyeballs.

Although this axe and arrow did not cause substantial damage to the Kui Niu, it also greatly consumed its true power and stimulated its nerves.

Roar~

Kui Niu was furious, it roared, and rushed forward violently with the power of the wilderness, knocking the top of the puppet Yanlong to the ground, and the huge Yanlong body fell, crushing the wall of the small courtyard and even the corridor with the main body of the Spring Rain Building.

The energy restraint of the magic circle was also broken by the bull strength that burst out with all his might, and the Kui Niu finally got out of the trap.

Seeing that Kui Niu broke through the trapped formation and toppled the Yan Dragon, he immediately let out a long breath of turbidity, this is the time when its old power is exhausted and the new power is not born, although this is only a moment, but for Qingshi, who has been waiting for this moment for a long time, this is enough.

The bluestone suddenly came out of the ground under Kui Niu's belly, and the cold light of the Moon Soul Sword in his hand flashed and gently inserted into Kui Niu's abdomen, reaching the handle.

Kui Niu is ten zhang long and six zhang high, and the moon soul sword of Qingshi is only three feet and six inches, and it cannot directly stab its heart, but the sword of Qingshi erupted with a violent and incomparable sword aura, like a sharp blade cut into the tofu, instantly crushing Kui Niu's internal organs and killing its vitality.

The current bluestone, the fourth stage of the elixir realm, the nine true qi is complete, and he has understood the four heavenly realms of earth, gold, wood, and wind, even if he fights alone, it is not much worse than this Delang, he used the magic array to set up an ambush to trap Delang, and he had to be covered by the puppet Yanlong and Chen Tianye Duan Wutian, so he naturally made a sneak attack and succeeded in one fell swoop.

The Kui Niu let out a scream of frustration, and the puppet Yanlong jumped up, opened its huge mouth with sharp teeth, and bit off most of the Kui Niu's neck in one bite, and then raised its head to the sky and let out a shocking roar.

Qingshi immediately took the puppet Yanlong, and the three of them did not go to the main entrance, but went around to the back of the small building, Duan Wutian gently knocked down a gap in the wall, and the three of them got out and walked down the small alley behind the wall.
