Soon, the hundreds of soldiers in Cangyan Emperor City were almost wiped out by Lin Yi and others, leaving only the black beard man to lead them.
The big man with the black beard was obviously at the end of his strength, and he fled to the distance with a feigned sword strike.
Lin Yi quickly flew over, blocking the way of the big man with a black beard, and smashed down the stone sword in his hand, striking with all his strength.
There was a look of horror in the eyes of the big man with a black beard, but the black iron epee in his hand was directly chopped into pieces by Lin Yi.
After that, the big man with a black beard could only resist with his arms, but how could his physical body block Lin Yi's sword skills.
When the sword fell, Lin Yi chopped off the arms of the big man with a black beard.
The iron sword caught up from behind, and the two swords slashed at the same time, that is, from the back, the body of the black bearded man was chopped into three pieces.
The crowd suddenly cheered, "Your Commander is mighty! Your lieutenant is mighty!"
In this battle, all the people in Cangyan Emperor City were wiped out, and Tie Dao also lost seventy or eighty men.
"Bury all the corpses of the brothers!" Tie Dao's expression was not very good, and he ordered coldly.
"Yes, Lord Commander!"
The crowd dug a big pit on the sandy mountain, and buried the dead brother carefully in it.
As for the cultivators in Cangyan Emperor City, all their valuables were taken away by the crowd, and then their bodies were thrown into the sandstorm.
"Go to the Spirit Crystal Mine!" Tie Dao and Lin Yi discussed the plan, and quickly led the crowd and continued to fly forward.
At this time, the sandstorm in the sand mountain became stronger and stronger, sweeping between the sky and the earth, like a big monster that devoured everything.
Lin Yi and the others had no choice but to avoid the huge sandstorm and approach the center of the sand mountain.
Finally, half a day later, Tie Dao and Lin Yi, leading hundreds of men, finally passed through the sandstorm and entered the deepest part of the sand mountain.
This place is very strange, there is no sand and dust, but a large piece of black rock, exposed on the ground, forming a thick layer.
Because the sand and dust blowing from the desert are almost completely blocked by the rolling sand hills, so this area is basically not covered by sand and dust. There are only black stones everywhere, one after another, each of which is very huge.
Looking around, this black stone area spreads for a distance of hundreds of thousands of meters, forming a large-scale special stone field.
"Here is the Spirit Crystal Mine?" Lin Yi asked.
Tie Dao nodded, "The City Lord sent someone to investigate, and there are a lot of spirit crystal ore hidden in this black stone, with a thickness of hundreds of meters!"
Everyone gasped when they heard this. Such a large-scale mine is hundreds of meters thick, and the number of spiritual crystals in it is simply astronomical. No wonder the two imperial cities want to compete for it.
But at this time, the entire Spirit Crystal Mine was full of people from Cangyan Emperor City. In every direction, there were a large number of monks forming a defensive formation. There were also soldiers patrolling non-stop in midair.
Obviously, Cangyan Emperor City's strict defense is to guard against the Wuji Emperor City.
If the subordinates like Tie Dao alone rushed down, they would probably be wiped out by the opponent soon.
"My lord, what shall we do now?"
Tie Dao pointed down, "Ambush first and wait for Yan Luo, this is the order of the Lord City Lord!"
As he said that, Tie Dao flew down first, and landed behind a sand mountain, and everyone also fell, closely following Tie Dao.
Here, it is very close to the Spirit Crystal Mine, and it is also very hidden, hiding in the sand hills, it is difficult to be found.
At night, the world is quiet except for the sound of wind and sand.
"Lin Yi, let's sneak into the Spirit Crystal Mine tonight and check the situation!" Tie Dao said, obviously planning ahead.
Lin Yi nodded.
The two quickly left the sand mountain, but they were close to the Spirit Crystal Mine. They didn't dare to fly in the air at all, so they could only run over quietly from the ground.
Under the darkness of night, on the sandy ground, two black shadows, like two arrows, rushed forward at an extremely fast speed.
"Remember, if there is an accident, run away immediately without hesitation!" Tie Dao said.
Lin Yi naturally knew the importance, nodded, followed the iron knife, and walked into the black stone area.
Strangely, when Lin Yi stepped onto the black stone, he clearly felt a force pressing down on his body.
The gravity in this black stone area has actually increased several times, which is very uncomfortable.
Lin Yi immediately released the power in Xuanfu to offset this gravity.
Tie Dao obviously also encountered this situation, and hastily released Xuanfu.
Of course, after entering the Blackstone area, everyone will be affected by gravity, and there is no difference between them.
"There is someone in front!" Tie Dao and Lin Yi quickly lay down and hid behind a boulder.
"There are a total of ten people, all of whom are in the Xiaohua period, and half of each person!" Tie Dao said.
Lin Yi nodded, met Tie Dao's eyes, and rushed out at the same time, his figure was silent, but he was almost at the limit.
Those ten monks were obviously on patrol, and they didn't feel anything, they just felt a chill in their necks, and then their heads fell to the ground.
Lin Yi killed five of them with a single sword strike.
As for the iron knife, swinging the two knives solved all of them without making any sound.
After finishing off the group of monks, Lin Yi and Tie Dao continued to sneak.
The defenses laid down by Cangyan Emperor City are indeed very tight, with a wave of guards every 100 meters.
However, with the fighting power of Lin Yi and Tie Dao, it is not difficult to deal with these guards silently.
Soon, the two killed five waves of guards in a row, and finally entered the middle of the Blackstone area.
Here, camps are stationed one after another, soldiers from Cangyan Emperor City are everywhere, and monks are constantly patrolling in mid-air.
The two of Lin Yi could only observe the surrounding area, secretly noting down all the terrain and the opponent's strength.
"Commander, they have eight tents in total, and outside each tent, there are at least a hundred monks in the Xiaohua period!" Lin Yi observed around and whispered.
Tie Dao nodded, frowning fiercely, "Besides, there are quite a few strong men in the Great Transformation Period. There are three commanders I saw just now!"
"Dahua period is not a big problem!" Lin Yi frowned lightly, raised his finger and pointed to a golden tent in the distance, "Look, the middle tent has no guards around it, it's very strange!"
Indeed, Lin Yi had already noticed that the largest tent, standing in the middle of the Lingjing Mine, was like a golden boulder, and it must be very important.
"Then there is only one explanation, the people inside don't need any protection at all!" Tie Dao's face changed, "Could it be..."
Lin Yi raised his head, his eyes were like torches, and he saw an invisible fluctuation above the golden tent, oppressing outwards, it was not a kind of power, but the aura of a strong man, "Could it be that Cangyan City Lord of the city!"
