"Lord, what is the origin of this Xuantian Empire? The four of us have only been in seclusion for almost two years, and suddenly this country appears?"

When they heard the word Xuantian, the four cultivators felt something was wrong and wanted to find out more.

"I'm not sure either, but according to intelligence, no other immortals have appeared in these armies, so please rest assured."

Listening to the king's words, the four of them sneered and would not believe it. The four of them had also stayed in this spiritual country for quite some time and already knew the king's character very well. The four of them avoided the king and began to communicate with their mental power.

'Could this Xuantian Empire be related to Xuantian Sect?'

"Need I say this? Of course there is. In the East Continent, apart from the Xuantian Sect, would any other force dare to do this?"

"Don't worry. I just checked the surroundings with my spiritual power. There are indeed no monks. However, the spiritual power contained in those armors is very strong. Although those who use them are mortals, we cannot take it lightly."

"Why think so much? Let's see how strong the opponent is first, and then make a decision. Besides, that armor is really good-looking and suits my taste!"

After the four of them finished communicating, they flew out of the city wall together and rushed towards the location of the Armored Legion. On the city wall behind them, the King of Ling Kingdom and the soldiers defending the city looked at the backs of the four people with hope. That was all their hope.

Chen Zhen and his four companions and 50 monks were hiding in the distance on the battlefield. Chen Zhen looked at the four monks attacking from the opposite side and asked Liu Zhi who was standing beside him.

"Liu Zhi, there are four people from the other side who are at the ninth level of Qi training. Should we go and help them?"

"Let me take a look at the situation first. To be honest, I am very curious about what level of cultivator this mortal can match with the spiritual armor. Now is an opportunity. Chen Zhen, aren't you curious?"

Liu Zhi made the suggestion with a smile, but in his heart he was very wary of the spiritual armor. After three days, this armored corps had improved very quickly in combat. During the first siege, most of the soldiers were still very stiff in controlling the armor, and they attacked in a methodical manner, but now their movements were very smooth, and after many battles, they were full of murderous aura, and they had killed many more people than the cultivators like himself. Moreover, he felt that this armor must have some other means.

"The 1000 people in the front row deploy shield defense, and the back row shoot!"

Yu Wen looked at the sword energy, fireballs and other attacks flying from afar and began to order the armored legion to fight. He was very excited. After three days, he finally met a monk and could fully exert the power of the armor.

One thousand armored soldiers deployed spiritual shields, forming a 500-meter-long and 200-meter-high spiritual wall in front of the legion, blocking attacks and providing shooting space for the armored soldiers behind.

Boom! Boom! The attacks of the four cultivators all hit the spiritual power wall, and a large number of ripples appeared on it. Some places were sunken, but they could not be broken. This kind of array shield was taught to Xiao Ningxue by Yu Yue. It can share the opponent's attack and improve the defense of the shield.

The four cultivators were shocked. Although they had never comprehended the momentum, the attack just now could easily destroy a small city. However, it didn't even break the shield. As independent cultivators, they were timid and cautious to begin with. After seeing the first round of attacks was fruitless, they had already considered retreating. However, the attacks of Yu Wen and others had also reached them at this time.

Dense spiritual power bullets continuously bombarded the spiritual power shields around the four people. After being improved, the speed of the spiritual power bullets was close to four times the speed of sound within a thousand meters, which was faster than that of an ordinary ninth-level Qi training cultivator, and they could fire continuously like a machine gun. This caused the four cultivators to be unable to fight back for a while, and they could only hold up the shield for passive defense.

"Turn on the maximum frequency of the spiritual power gun and continue attacking, suppressing them with firepower until one of the power crystals is used up."

While giving orders, Yu Wen adjusted the regulator on the spiritual power gun to the highest frequency. Instantly, the firepower of the armored legion increased to a higher level, reaching more than a thousand spiritual power bullets per minute, forcing the four opposing monks to retreat.

"Don't linger any longer. As long as the green mountains remain, there will be no shortage of firewood. Let's retreat!"

Looking at the ripples of the spiritual shield in front of them and the rapidly consumed spiritual power in their bodies, one of the four people ran away first, and the other three also turned around and fled. These armors had a lot of attacks, but the destructive power of each light ball was still too low, so it was very easy for them to escape.

Looking at the four monks fleeing, although they didn't know what level of cultivation they had, they defeated the monks, which made the soldiers of the Armored Corps cheer. Yu Wen saw that there was nothing he could do about them running away, so he could only let the other armors stop attacking and remove the spiritual shields.

"Armored Legion, listen up! Our goal has not been achieved yet. It is too early to cheer now. Let's continue attacking the capital of the Spirit Nation!"

As Yu Wen gave the order, the cheers around gradually faded away, and everyone began to accelerate towards the capital. The black-armored cavalry behind them had already been stunned. The result of this battle left a deep impression on these black-armored cavalry, and they remembered it firmly in their hearts, making them even more eager to be promoted to the armored corps.

The ruler of Ling Kingdom stared blankly at the four monks fleeing. The ministers and generals around him came to their senses and gave suggestions.

"Lord, let's surrender. At least we can save our lives."

"Yes, even the immortals have fled. How can we mortals fight this army? This is courting death! Please order us to surrender, Lord!"

Listening to the words around him, although the king wanted to kill these people, he also knew that the situation was hopeless and he had no chance. Even if he did not surrender, these traitors would force him to abdicate, and the end of the royal family would be even more miserable. It would be better to surrender early so that he could negotiate terms. With this in mind, the king spoke.

"Let the soldiers in the city lay down their weapons, take off their armor, open the city gates and surrender..."

After saying this, the king's entire spirit became weak. Several ministers behind him felt a little sorry to see him like this. After all, they had been king and ministers for many years. But since things had come to this, they might as well open the gate and surrender.

Yu Wen, who was almost rushing to the city gate, looked at the opened city gate in surprise. Many soldiers who were not wearing armor and did not hold weapons walked out. The leading king was still wearing a dragon robe. When these people saw the armored army up close, their faces became even more panicked, and then they all knelt down and surrendered.

"Stop, the other side surrenders."

Yu Wen slowed down, waved his hand to stop, then walked towards the group of people step by step, looked at the king who was kneeling in the front and said.

"Are you the ruler of the Spirit Kingdom?"

"Yes…"

The king lowered his head and spoke in a weak tone. After getting the answer, Yu Wen ignored him and led the armored legion into the city first. Even the monks were defeated by them. What was there to be afraid of in this mortal city? After the battle just now, Yu Wen's confidence was greatly inflated.

After Ling Kingdom surrendered, the handover went smoothly. However, because the cultivators who came did not have much management experience, Chen Zhen could only send a message asking Luo Youran to send someone to take over Ling Kingdom.

At night, after the celebration, the army of Xuantian Empire left some people to keep watch, and most of them went to sleep. In a courtyard in the Ling Kingdom Palace, Yu Wen, who was not wearing armor, was asking to see Chen Zhen. After being allowed, he entered the room.

"Join the coach!"

"What's the matter, Yu Wen?"

Chen Zhen was originally practicing, and he felt a little uncomfortable being disturbed, but he was the commander of the army after all, so it was normal for Yu Wen to come to him.

"Commander, this is what I want to say. One of the legion's armor energy crystals has been consumed after today's battle. Now each armor has two energy crystals left. If we encounter monks later, the crystals will not be enough. I hope that the commander and Lord Xiao of Tianshu City will need some spare energy crystals."

"I understand. You can go down and rest first. You still have to attack other countries tomorrow."

"As ordered!"

After Yu Wen bowed, he left the room and closed the door. Chen Zhen took out the jade talisman and input the message. The jade talisman turned into a stream of light and left. Then he went to Liu Zhi's room.

"Liu Zhi, do you really think this kind of armor-like magical weapon can threaten our status?"

"Yes, especially after watching today's battle, I am even more certain. Now the Armored Corps has only 3,000 people and can defeat four ninth-level Qi training cultivators. What if the number increases to tens of thousands, or even hundreds of thousands? By then, the status of ordinary foundation-building cultivators like us who have not comprehended the realm of intention will definitely decline."

Liu Zhi slowly spoke out his analysis. Chen Zhen's face looked a little unhappy after hearing it, but he still refuted.

"Liu Zhi, have you ever thought about the cost of this armor? This armor is made entirely of low-grade spiritual materials, hundreds of thousands? That would probably drain half of Xuantian Sect's money! Do you think it's possible?"

"Chen Zhen, I'm not convinced by you now, but we'll have to wait and see. The four of us should speed up our cultivation so that one of us can reach the state of mind and build a foundation as soon as possible, so that we don't have to worry about this matter."

Afterwards, Chen Zhen returned to his room to practice. Although he still doubted Liu Zhi's words, this conversation took root in his heart and made him practice harder.

……

Five days later.

In Xiao Ningxue's room in the Tianshu City Lord's Mansion, Lin Ji slowly opened his eyes, and a mysterious aura flashed by.
