This is the fourth Yin Qi gushing, after several Yin Qi gushes, Bai Cheng discovered two rules, the first is that each Yin Qi gushing must be separated by an hour, and the second is that the skeleton warriors that appear after each gushing are more powerful than the last one.

The first law was beneficial to Bai Cheng and the others, but the second law was a bit bad, Bai Cheng was worried that after three days, thousands of Refining God Masters would suddenly appear from underground.

The first wave of skeleton warriors was slow and staggered when they walked, the second wave of skeleton warriors was already agile and not inferior to ordinary soldiers, and the third wave of skeleton warriors were all easy to use the martial arts of the Tendon Realm, although their cultivation was still shallow, but it was also an extremely difficult force to fight.

Now in this fourth wave, although I don't know how they cultivate, just look at the unity of orders and the orderly advance and retreat, and I know that it is not comparable to the previous waves of guerrillas.

The skeleton warriors were neatly divided into four teams, lined up under the arrow tower, and lined up on all sides of the arrow tower to defend it, but they were not in a hurry to attack, but sat back and watched the previous wave of skeleton warriors attack.

Bai Cheng and Yan Gaofei stood on top of the arrow tower, although they had doubts in their hearts, their subordinates were not slow at all, and they were not leaky, and they were solid.

Half an hour later, the head of the last skeleton warrior was cut off, and the corpse was separated and turned into a cloud of black gas, which was still swallowed by the Xuantian Wujin Python.

With the skeletal warrior gone, the four teams of men and horses below the arrow tower finally began to move. Of the four teams of skeleton warriors, the first half of each team took a step forward, while the second half of the team took a step back.

In an instant, the four teams turned into eight teams, and when Yan Gaofei saw this scene, his face changed, and he said, "It's not good, be careful!"

Before the words fell, I saw that the four teams in front of me did not move, and the four teams behind took out their longbows and shot arrows with bows.

I only heard the sound of "buzz", and long arrows rained down on the arrow tower.

Reminded by the wild goose flying high, Bai Cheng had already prepared, and with a flick of the spear in his hand, he pushed dozens of long arrows away, but then more sharp arrows flew in.

Fortunately, the arrow tower is ten zhang high, and the long arrow has lost its strength so far, otherwise hundreds of sharp arrows will attack, even if Baicheng's martial arts are ten times higher, it will be difficult to protect it.

Bai Cheng and Yan Gaofei are two, one is located in the southeast corner, and the other is located in the northwest corner, and each of them has to protect both sides.

Although Yan Gaofei's martial arts are higher than Bai Cheng's, he suffers from the fact that the long knife in his hand is shorter, which is not as convenient as the spear in Bai Cheng's hand, and for a while, he is a little stretched. Thanks to the presence of the Xuantian Wujin Python, he knocked down the sharp arrows that he couldn't pull away one by one.

The wild goose flying high and Bai Cheng are working hard to resist. The old club, Sun Jiangguan and Lin Suhuan settled in the building, ignoring the turmoil in the outside world, and did not even raise their eyelids.

Yan Gaofei was secretly surprised in his heart, he was a friend of the old Zhou family, and knew that although he was an old man now, he had also charged into battle when he was young, crisscrossing the north and south of the river, and he didn't know how many strong enemies he had fought with, so he had developed such a resolute heart. General Sun is a fierce general of the imperial court, leading the army for many years, conquering the east and the west, although he despises this person, but also knows that this person also has the bearing of a general.

Only Lin Su was still there, which surprised him, he had a very bad impression of Lin Su when he met twice, not to mention frivolity, and liked to provoke right and wrong, but he didn't expect this person to also have this temperament that is not afraid of life and death, just in terms of this character, he is not a mediocre person, but he is also an important person in the Daomen.

Yan and Bai were finally outnumbered, although their martial arts were exquisite, they were suppressed by the rain of arrows layer upon layer, and they left the battlement wall step by step, retreating towards the middle of the arrow tower, unable to check the skeleton warriors who climbed up.

Two quarters of an hour later, the skeletal warrior had shot three waves of arrows, and the two had been forced three steps away from the battlement wall.

At this moment, the rain of arrows suddenly stopped!

The wild goose is experienced and agile, and he doesn't look out, he stretches out his hand and swings it out along the battlement wall, only to hear three crisp sounds, and three clouds of black gas suddenly rise.

After he swung his sword, he didn't look at it, stepped lightly, and jumped onto the other side of the battlement wall, where three skeleton warriors were already able to climb the arrow tower.

The wild goose flew high and swung his long knife, chopping off the two skeleton warriors with a single sword, but the remaining one took the opportunity to climb up. The skeletal warrior climbed up, speared the goose in his hand, and stabbed it in the heart. It's just that it didn't guard against a snake tail like a steel whip from above, and it was whipped to pieces.

Taking advantage of the gap between removing a few skeleton warriors, Yan Gaofei looked down and saw dozens of skeleton warriors climbing along the stone crevices towards the top of the arrow tower, and the nearest few of them were only more than two feet away from the top.

These skeleton warriors were roughly divided into three waves, each of which was twelve, and they climbed along the four stone walls of the arrow tower, and the distance between each wave was three zhang.

Yan Gaofei is a master of qi training, if it is in normal times, as long as he swings out with a knife, the sword qi is several feet longitudinal, and it is not difficult to crush the people below. But now these are skeleton warriors, tangible and substantial, and the sword is difficult to hurt, and he is helpless.

Yan Gaofei was bored in his heart, and turned his head to look at Bai Cheng, only to see Bai Cheng holding a spear in his hand, squatting on the battlement wall, not knowing what he was thinking.

Feeling the gaze of the wild goose flying high, Bai Cheng turned around and said: "This wave of skeletons is not aggressive, they have a rain of arrows as a cover, we can't shoot in advance, but if they really rush up one or two, it will be even more difficult for us to be distracted to prevent the rain of arrows." ”

Yan Gaofei nodded and said: "The arrow tower is steep and can only accommodate a few people to climb, so they only send a few people at a time, and everyone else is downstairs to greet with a rain of arrows, this is a standard tactic in the army, there is no good way to crack it." ”

Bai Cheng shook his head and said, "If the real army is used, there is naturally no way to crack it, but it is not impossible to clean up these skeleton warriors. ”

Yan Gaofei's eyes lit up and asked, "Do you have a way?"

Bai Cheng didn't answer directly, and asked, "How long can Brother Yan guard alone?"

Yan Gaofei thought for a while and said, "If you have a spear in your hand, there will be no problem for a while." ”

Bai Cheng shook his hand, threw the spear to Yan Gaofei, and said, "After this wave of skeleton warriors rushes up, I will look for an opportunity to go down the arrow tower, but Brother Yan's long knife will be borrowed from me." ”

Yan Gaofei did not hesitate and threw the long knife in his hand to Bai Cheng.

The knife is three feet long, the back is thick and the blade is thin, the blade is shiny, and the handle is pitch black.

Bai Cheng thought that this long knife was long and thick, but he was afraid that it would be very heavy, but he didn't expect that after getting it, it was as light as nothing, a few points lighter than a wooden knife, and he couldn't help but be stunned.

While the two were talking, another wave of arrows arrived. The two of them guarded the two sides separately, blocking for a while, resisting the rain of arrows.

Just as the rain of arrows stopped, several more skeletal warriors climbed the battlement wall.

Bai Cheng didn't have time to make a move. Yan Gaofei smiled coldly, and with a shake of the spear, dozens of spear flowers scattered in all directions, and more than ten skeleton warriors were ignited together with one shot.

Bai Cheng was shocked, and the high level of Yan Gaofei's marksmanship was above his knife skills. If it is an ordinary wooden-handled gun, it is not difficult to shake out the spear flowers, but this spear is made of cold iron, which is extremely strong, and he can even shake out more than ten spear flowers, this kind of marksmanship is the only one seen in Bai Cheng's life.

But the situation was urgent, and Bai Cheng didn't have time to think about it, so he took advantage of the goose's flying skills, held a long knife in his hand, flew over the battlement wall, lowered his head and rushed down to the bottom of the arrow tower. (To be continued.) )
