Li Yi caught the ghost crow released by Bi Fang, and when Bi Fang sensed it, he learned the information of Bi Fang's location from the eyes of the ghost crow.

Bi Fang has a large number of troops around him, and his location is extremely open, unlike Li Yi who is hiding in a cave now.

The black ghost brother recognized the location of those people at a glance.

It is the Valley of Horror thousands of miles away from where Yongcheng is located.

Even if Bi Fang rushed back with all his might, it would take several hours.

"They are out in force at the moment, and it is a good opportunity for us to conquer Yongcheng. As soon as Li heard the black ghost brother say that Bifang's army was thousands of miles away from here, a gleam suddenly appeared in his eyes.

Hearing Li Yi's words, a look of excitement also appeared on the faces of these Yin cultivators.

This was something that they couldn't think of when they followed Kui Niu, but now Li Yi not only let them regain their dignity, but also gave them the opportunity to become an official and make a contribution.

Li Yi saw that the eyes of these sergeants showed a surging battle intent. Understand that the fighter plane is fleeting, and now is the time to attack!

Li Yi suddenly had a raging battle intent rising in his body, and held the half-immortal sword composed of Lihattian and Yun Qingtian in his hand.

Pointing in the direction of Yongcheng, he roared angrily, "Fight to the death!"

"Fight to the death!" all the sergeants beside Li Yi stood up suddenly, like a long black dragon, and they all let out an earth-shattering roar.

"The first and second arrays, take the lead with me and attack the main gate of Yongcheng. The remaining three to eight columns were lying in ambush at the gate of the small city in the east-west direction, using fireworks as a letter to launch a fierce attack!" Li Yi quickly said his battle plan.

The sergeants in Kui Niu's department are also well-trained troops, but they were not able to exert their combat power by Kui Niu before.

After being re-aroused by Li Yi, he has extremely strong combat effectiveness.

At this moment, after Li gave the order, the remaining eight commanders of the array led the army to the battle site in turn.

Li Yi led the first and second arrays and rushed towards the main gate of Yongcheng.

There are also some millions of similar yin cultivators in the main city of Yongcheng.

Most of them are below the golden pill, and they are lowly cultivated, and they have not yet condensed into entities.

Their presence is extremely important for the maintenance of the entire Underworld.

With this population, one can produce the Yin Qi Pill for cultivation.

These Yin Qi Pills need to be swallowed by ordinary monks before they can be condensed and formed.

Yin cultivation above the Jin Dan, condensing the Yin Qi Pill from the Yin Qi is too much of a waste of time.

And those low-level Yin Spirits used the Yin Qi Pill as a tax as a qualification to stay in the city.

And the Yongcheng defenders provided them with security guards.

Low-level Yin cultivators, without the blessing, can easily become the ration of other Yin cultivators.

The strategic position of a city is also extremely important.

Li Yi's troops left all the Yin Qi Pills in the camp.

If Yongcheng is not seized, I am afraid that it will take an extremely long time to even restore the Yin Qi cultivation, which will also make Li Yi's troops lose their flexibility.

It is extremely important for Li Yi to seize Yongcheng.

Li Yi brought two thousand Yin cultivators, and there were about two hundred of these Yin cultivators.

These underground Yin Cultivators are very few for the Combined Attack Formation.

But Li had that Song Teng's storage bag in his hand, and there were at least dozens of combined attack formations in it.

As a demonic cultivator, Song Teng was extremely similar to the yin qi of these yin cultivators.

These Yin cultivators used Song Teng's formation, which can be said to be handy.

Li Yi searched for the combined attack formation from Song Teng's storage bag and taught it to these two thousand people, and more than 6,000 other monks.

The array formed by eleven people can share the damage, and the attack power is even more condensed with the power of eleven people.

It became extremely difficult to kill Li Yi's troops.

The two hundred arrays formed by Li Yi's troops were like invincible chariots, running towards Yongcheng.

"Kill me!"

Li pointed with one arm and one finger.

Two hundred combined strike circles engaged the defenders of Nayong City.

"Enemy attack! Enemy attack!" Suddenly, the alarm sounded on the head of Yongcheng City.

Li Yi's troops' combat strength was obviously a level stronger than that of the Yongcheng defenders.

In the face of an enemy nearly ten times larger, it seems to be invincible.

Especially with a flick of Li Yi's wrist, dozens of Yin cultivators died under the flying sword.

Li Yi had relied on these troops to capture Yongcheng, which was guarded by several times the defenders.

However, the city of Yongcheng was also lit up with a ball of light, and hundreds of extremely powerful giant crossbows were put up.

The base of the crossbow was as large as a house, and shone with a faint light.

The crossbow was huge, but there were no arrows on the bowstring.

There were dozens of monks sitting on these huge crossbow racks, and under the yin power infused by these dozens of Jindan Yin cultivators together, an arrow as huge as a spear appeared on the bowstring.

Shout......

The giant crossbow seemed to have finished gathering momentum, and pitch-black spears shot out one after another.

Attack on top of the array of combo attacks in the sky.

This black arrow is enough to threaten the Great Perfection of the Yuan Infant.

At this moment, the two hundred arrays of Li Yi's troops were fired in a volley by the giant crossbow, and dozens of them were shot down in an instant.

"How can there be so many defenders of Yongcheng this time. Li Yi looked at the giant crossbow on the head of the city wall, and couldn't help frowning.

These hundreds of giant crossbows require nearly 10,000 Yin cultivators to pull them.

Those giant crossbows could even pose a threat to Li Yi.

So many Yin cultivators were pulling giant crossbows, but Li Yi saw that there were still many resistance forces on the city wall.

Protect those giant ballestas. It made it difficult for Li Yi's array to rush in.

Li Yi's array is all treasures, and under a salvo, dozens of them will be lost, how can this make Li Yi accept.

"Sword Annihilation!" Li Yi suddenly dispersed the hatred of the sky into a flying sword, and sent out a sword annihilation.

In an instant, a violent storm of sword qi razed a giant crossbow bunker in the shape of a bunker to the ground.

At least hundreds of Yin cultivators were destroyed under Li Yi's sword.

However, it was impossible for Li Yi's sword to be used unscrupulously, and a single sword annihilation had already drained nearly one-tenth of Li Yi's spiritual power.

But there are still hundreds of giant crossbow bunkers on this wall. Even if Li Yi's spiritual power is drained, it is still a drop in the bucket.

When Li Yi attacked the city before, there were only a few dozen of these giant crossbow bunkers, and they were destroyed by Li Yi's several rounds of attacks.

Call......

Two white flames suddenly rose in Li Yi's hands, and Li Yi relied on the fireball technique to break through this Yongcheng before.

The fireball technique consumes much less spiritual power than the sword extinguishing, as long as Li finishes two shots, and then takes out the best spirit stone from the storage bag to recover the lost spiritual power.

Li Yi's spiritual power can maintain a continuous fireball attack.

The defenders below knew the power of Li Yi's fireball, and suddenly there was a shout from below.

"All the black cloud crossbows will shoot at the man in one volley!"

Li Yi had attacked Yongcheng once, and these people had already understood Li Yi's methods.

Suddenly, all the giant crossbow bunkers turned around and pointed at Li Yi in the air.

Being pointed at by hundreds of black cloud crossbows, Li Yi suddenly felt a thrill in his heart.

Even if Li Yizheng was a master of art and boldness, it was impossible to ignore these hundreds of attacks.

"Wind and thunder!"

Li let out a loud cry, and his speed skyrocketed, and he ran up and down the city wall.

"Hurry up and release the arrows!"

The commander of the city's guards saw Li Yi flying underground, and immediately understood Li Yi's intentions.

If Li Yi flew close to the ground, then their Black Cloud Crossbow would enter the dead end of the attack.

gargling gargling ......

Under the order of the commander of the city's guards, all the arrows shot at Li Yi together.

There was a gargling sound.

But Li Yi's speed was extremely fast, rubbing the ground, swimming on the ground like a swimming fish.

Several arrows almost grazed Li's scalp and flew over.

Rumble......

Li Yi dodged the first round of attack of the Black Cloud Crossbow and flew two fireballs towards the city wall.

One fireball was thrown at the giant crossbow, and the other was thrown at the person who made the sound.

"Stop me!" the commander of the city's guards looked horrified when he saw the fireball in the sky.

He roared at the monk beside him.

Suddenly, dozens of sergeants flew up and blocked Li Yi's fireball technique in the air.

Dozens of monks were completely reduced to ashes in the air, but they allowed the city guards below to escape.

"Hmph!" Li Yiyi wanted to directly blast the person who made the sound to death, but now that he was hiding in the sea of people, Li Yi's fireball technique was too wasteful to waste on these low-level monks.

Suddenly snorted coldly, his body was like a swimming fish, holding a superb spirit stone in one hand and Lihate Heaven in the other, strangling the enemy army on the city wall.

Li Yi and their sergeants were fighting hand-to-hand, and these black cloud crossbows suddenly had no target.

Moreover, Li Yiyi's fireball technique also made the city guard a little jealous, and he didn't dare to show his head again.

At this moment, the sound of killing on the city wall shook the sky, and the black cloud crossbow just now shot at Li Yi together, and the two commanders also led the troops to eliminate dozens of giant crossbow bunkers.

But the battle also fell into an extremely difficult situation.

Without the deterrence of Li Yi's fireball technique, the arrays in the sky were shot down from time to time.

"Commander, don't you give a signal yet?" The two thousand men fought with a tenfold enemy.

The troops under these commanders are also their flesh.

The commander of the thousand, Sun Ji, couldn't help but ask Li Yi for advice.

Because the remaining six arrays are still on hold. The two arrays of them were fighting to the death, and it was normal for them to have some imbalance in their hearts.

"No, they're not messing around yet! Li Yi looked at the long battle line of the city wall.

At the edge of that line was the east-west entrance to the city.

There were also thousands of troops there, which were not used.

What Li Yi has to do now is to use these two thousand Yin cultivators and himself to pry this entire city wall battle front.

Once they are in chaos, the ambush can be of maximum use.

"Body, you quickly let the mosquito beast send it to me!" Li Yi couldn't help but sense his mind with the body in the distance.

Li Yi's mosquito beast is close to the body and likes to stay by the body's side.

But at this moment, the mosquito beast is no longer there, and Li Yi may not be able to hold on.

"Good. "Li Yi's body is immersed in fiery magma at the moment.

Hearing the doppelganger's cry for help, he immediately flew out of the magma.

"You go too. Li Yi placed the ghost beast on his chest on the chest of the mosquito beast.

The ghost beast seemed to understand what Li Yi meant, and without any resistance, it attached itself to the mosquito beast.

Buzzing......

Li Yi's mosquito beast suddenly let out a buzzing roar and flew towards the location of Li Yi's clone at an extremely fast speed.
