The two have been scuffling together, you come and go, and they don't let each other go.

And as the battle deepened, more biochemical pill metamorphosis and metamorphosis effects were presented in front of everyone's eyes one by one.

It looks like green and elastic skin, but it has an almost perfect self-repair ability, and the wounds that are deep in the bones are already intact in the blink of an eye, and there is not even a scar.

And this is only one aspect of it, through careful observation, Chu Yan also found a lot of surprises.

Lightning-like speed, like the body of a spirit snake, super sensory organs, and so on...... These have been reinforced to an outrageous point that is completely beyond people's perception.

The most important thing is that after Chu Yan reduced the measurement by one-fifth, the tiger master became less irritable than just now, or retained more humanity.

This is the most important thing, because no matter how strong and high the combat power is, it is just a group of crazy people who cannot be restrained, and when facing the cultivators and well-trained troops, they are just a group of mad dogs waiting to be slaughtered after all, and they have no combat skills to speak of, if so, what is the point at all.

The hundred pills were melted again, and one hundred and twenty bottles of liquid medicine were placed in front of everyone's eyes.

These one hundred and twenty people are elites carefully selected by the instructors, although they are not cultivators, but their endurance and concentration are not comparable to ordinary people, so that after taking the biochemical pill liquid, they can control their bestial side more effectively.

In the evening, everyone gathered together, and the tiger master was full of praise for Chu Yan's endless methods, if those soldiers of the Yanhuang Ancient Kingdom could have such armor and biochemical elixir, even if the Immortal Realm and Demon Domain joined forces, they would not be able to praise it at all.

As for Ou Yefeng of the Medicine Refining Guild, he was not as calm as the instructors, because judging from Chu Yan's age, he was no more than twenty-five years old at most, but why could he refine such a powerful pill and design such a powerful armor. There is also a city in the sky that continues to be built, which makes the old man puzzled.

You must know that although Ou Yefeng's cultivation is not high, those who can enter the Medicine Refining Guild are not ordinary people. Although the old man was skilled in mining, stone blocking, and casting methods, he was also a great alchemist, and with his experience, these things were unheard of, and his heart was shocked, and at the same time, he was deeply impressed by Chu Yan's strange ideas and superb methods.

Chu Yan quietly left the table. Alone in the cave where the parts of the Sky City were stored, I was very satisfied when I looked at the mountains of iron parts.

With Ou Yefeng supervising him, he is very relieved, believing that it will not take long for the Sky City to be built, and with the Iron Legion and biochemical warriors, it is enough to compete with the fairy world and the demon realm.

"Young master, Liu Tiehammer is here. ”

Just when Chu Yan was looking forward to a better future, the instructor ran over.

Chu Yan was taken aback, and when he was leaving, he left Liu Tiezhu in the new city. But now that he has suddenly come here, it is obvious that something has happened to Xincheng.

Sure enough, when he saw Liu Tiehammer covered in blood, Chu Yan knew that he was right.

"Ergou, why did you run here, if it weren't for the ghost's quick brain, I wouldn't be able to remember here. ”

Liu Tiehammer took a few steps to greet him, "The reinforcements from the Blood Jade Empire have arrived, we really can't resist it, so we asked me to find you back." ”

Chu Yan nodded. Knowing that the situation was critical at the moment, he immediately asked the instructors to assemble the Iron Legion, and at the same time planned to bring the first batch of biochemical warriors to see how their combat strength was.

Today, the Iron Legion has grown to two and a half thousand. The captain is the instructor and the tiger master, and it doesn't take long for them to assemble, and everyone is eager to try, and the fighting spirit is high.

This place itself is very close to the south, and the armor of the Iron Legion has the Soaring Runes and Wind Breaking Runes on it, and the Biochemical Warriors and Chu Yan and others are riding on the backs of the Iron Legion. When the sky was light, I came to the mountains fifty miles away from the new city.

Two days ago, the reinforcements of the Blood Jade Empire arrived, a full 100,000 people, and the leading figure was called Ma Changfeng, who was the generalissimo of the Blood Jade Empire, and the seventh-order cultivation of the Reincarnation Realm.

Under the leadership of Ma Changfeng, the army went straight to Xincheng and immediately launched a fierce attack.

Among these 100,000 troops, there is a very special team, they are the orc army that the Blood Jade Empire is proud of, and it is their participation in the war that has caused the Three Realms Alliance to suffer heavy casualties, and now the new city is already in danger, if it weren't for Gu Tianduo carving steel runes on the city wall, I am afraid that the city would have been destroyed long ago.

Chu Yan stood halfway up the mountain, and vaguely saw that the army of the Blood Jade Empire was still attacking frantically, and the orc army that Liu Tiehammer said was also among them.

"Damn, these orc armies are so powerful. ”

Liu Tiehammer said with palpitations: "Those guys with wings fly very fast, and many people are blocked by a sword before they can react; there are also guys with human heads, but the lower half of their bodies are like lions, they run extremely fast, and their power is infinite, and the throwing spears thrown can fly up the city wall; and there are also some guys who seem to be short in stature, but they can ...... Yes...... Eh, it's pretty awesome, anyway. ”

Listening to Liu Tiehammer's introduction, Chu Yan nodded solemnly, "Big brother, you first find a way to go back, and tell them that they don't have to worry, I have a way to deal with them." ”

"Okay, then I'll go back, but Ergou should be careful, these guys are very powerful. ”

After speaking, Liu Tiehammer had already galloped down and went straight to the new city.

"Instructor, gather your men and get ready to go. ”

After speaking, Chu Yan shook his head helplessly, turned around and went down the mountain.

To be honest, Chu Yan didn't want the people of the Immortal Realm and the Demon Domain to see the Iron Legion, especially the biochemical warriors right now.

Because Chu Yan's strength is still very weak now, although the combat power of the Iron Legion is very strong, there are only two thousand five hundred people, and the biochemical warriors are less than two hundred, in case the Immortal Realm and the Demon Domain are afraid of its strength, they will definitely try their best to eliminate these people.

Although this will be very difficult, and there is also the support of the Alchemy Guild behind the scenes, it is also very dangerous, if there is any mistake, the achievements of the nearly three years of hard work will be ruined and will be wiped out.

And it will also arouse the suspicion of the fairy world and the demon realm, why did Chu Yan secretly build such a strange army, and what is the purpose, the Heavenly Emperor and the Demon Queen are both old monsters who have lived for nearly ten thousand years, and it is not difficult to think that it may be aimed at himself.

With so many factors added together, Chu Yan almost didn't have to think deeply to know what kind of difficult situation he would face after this battle.

But he didn't have any way, the new city was in danger right now, and after breaking the city, blood would flow like a river, and the confidence that the Terran side had built up with great difficulty would also be completely crushed, and at the same time, it would further fuel the arrogance of the Blood Jade Empire.

Although I knew some about the past of the Blood Jade Empire in Shanyi, it was already 10,000 years ago, and now that time has passed, the Fighting Spirit Continent has undergone great changes, and I believe that the same is true within the Blood Jade Empire, otherwise it would not be unreasonable, and there are even people like Huangfu Yuebai who have a small belly and chicken intestines, and they can also sit firmly in the second position of the elder group.

Although he wanted to win them over to fight against the Immortal Realm and the Demon Domain, he still said that if he was stubborn and insisted on going his own way, just wanting to restore his status as the overlord of 10,000 years ago, then when they got their wish, who would dare to guarantee that the Blood Jade Empire would not be like the current Immortal Realm and the Demon Realm, maybe by that time, the situation would be much worse than now.

With a long sigh again, Chu Yan looked at the Iron Legion and the Biochemical Warriors on the opposite side.

After some thought, Chu Yan decided to divide the Iron Legion into three, led by the instructor, Tiger Master and Xu Fei, and the biochemical warrior was handed over to Scar.

In the last battle in Los Angeles, Chu Yan saw the potential of Xu Fei's command ability, so he planned to let him have more experience and give him a team.

"Instructor, you lead the five hundred steel legions through the air, remember, you must be near the city walls before you start, Scar's biochemical warriors will assist you. ”

Saying that, Chu Yan looked at Hu Ye and Xu Fei again, "The two of you each lead a thousand steel legions to attack the two wings of the Blood Jade Empire's army, remember, the more chaos the better." ”

"Young master, don't worry, Lao Tzu promises to complete the task. The tiger master patted his chest confidently, and the other three people clicked together, and then took off into the air, and disappeared without a trace in the blink of an eye.

Seeing that these people had already left, Chu Yan turned his head and glanced at Su You, "You hurry back to the main hall of the Medicine Refining Guild and bring more masters over, the more the better." ”

Su You nodded, knowing that Chu Yan really had no choice, otherwise he would not have exposed the Iron Legion and the Biochemical Warriors in front of the Immortal Realm and the Demon Domain, and now he asked the Medicine Refining Guild for help.

"Husband, be careful yourself, I'll be back soon. ”

With a faint halo flashing, Su Yu had disappeared, and Chu Yan's entire temperament had changed dramatically.

The heavy anger swirled around his body, almost condensed, and the next moment, a lone shadow had appeared in his hand, and he smiled coldly, "Yue'er, the rear of the Blood Jade Empire's army is you and mine." ”

"Okay...... "Yue Wujian looked very excited, "After the two little ones came out last time, they have been making noise now, as if they haven't had enough fun, just let them have fun again this time." ”

At this time, the Iron Legion had already started to move, although the number was small, but with the unparalleled combat power, it really stirred up a thousand waves with one stone, and killed the Blood Jade Empire by surprise.

Among the reinforcements of the Blood Jade Empire, only Tu Guang had seen the power of the Iron Legion, looking at the steel giants armed to the teeth like a wind, the giant swords and axes in their hands were like lightning, leaving stumps and broken arms all over the ground, and a scene of rivers of blood.

"It's them, it's them......" Tu Guang shouted again and again, and at the same time, the centaur in the orc army of commanders greeted him. (To be continued.) )
