After Chen Chunan and the three of them passed through the fog barrier at the gate of the city, they unexpectedly appeared next to the ravine that was once a flat land.

The fog barrier behind them disappeared, and they could no longer return to the ancient city to notify Zhang Ruochen and the others who were still staying in the city.

The cold wind here is cold, the wind is gusting, and the cold is outrageous.

Before, the three of them hadn't approached the ravine, but they recognized it at a glance.

It's just that it's so cold here, and the long nights and colds of the whole desert seem to start here.

Rumble!

An explosion suddenly sounded in the distance, and powerful energy surged out, and the entire space vibrate.

"It seems that someone is fighting. Chen Chunan's expressions became solemn at the same time.

"Could it be that the general has sent someone to investigate the news again?" Chen Chunan guessed.

"It doesn't matter who they are, just go and see them. As soon as Cao Gui's voice fell, he took the lead in stepping towards the place where the explosion came from.

Rumble!

They had been walking through the desert for days, and had never seen a single living person except Woolray.

However, at this moment, they actually heard the sound of someone fighting, which filled their hearts with all kinds of doubts.

"Who will they be?" asked Li Ba suspiciously.

"The battle ahead looks fierce, could it be...... Are they really another wave of men sent by the Great General?" Li Ba was also suspicious.

Boom, boom, boom......

"In addition to the sound of swords chopping, there seems to be the sound of energy cannonballs, could it be that Wu Lei is surrounded by the men and horses of the Prairie Tribal Alliance?" Chen Chunan speculated again.

Another earth-shattering explosion sounded, surging out of surging energy, shaking all directions, and the entire world was shaken, making people tremble.

Sneer......

As the three approached, in addition to the sound of explosions, they also heard the sound of swords slashing, as well as the sound of shouts of killing.

An energy cannonball blasted out from the direction they had just been, heading straight into the distance with earth-shattering energy.

"This is really an attack from Woo Lei's metal man, he shouldn't be really surrounded by people, right?" Chen Chunan said.

"Something is wrong. Cao Gui suddenly noticed a hint of abnormality, he listened carefully to the battle in the distance, and then said to Chen Chunan and Li Badao: "It seems that there is more than one metal man there, and their battle is probably even more fierce than we imagined." ”

Rumble!

"Quick, dodge. ”

Another roar and Huang Ying's voice sounded in Chen Chunan's mind almost at the same time, and he subconsciously pushed Cao Gui and Li Ba away, and then lay on his stomach on the cold sand.

"That's ......" Chen Chunan's eyes widened, he saw a total of three metal men, and there were a large number of soldiers in strange costumes beside those three metal men.

Dressed in coats made from the fur of various beasts and armed with a scimitar, the soldiers were fighting alongside the metal men, and their enemies turned out to be three green-haired monsters.

The strength of the green-haired monster, Chen Chunan had personally experienced it not long ago, with the assistance of Zhang Ruochen, a powerhouse in the Imperial Spirit Realm and the metal man operated by Wu Lei, as well as the assistance of the Buddhist scriptures and Taoist scriptures, they killed a green-haired monster with difficulty.

Chen Chunan and Li Ba also became more solemn, they also heard the sound of more than one metal man fighting, and they inexplicably had a bad premonition in their hearts.

"Be careful, the battle ahead may not be easy. ”

The three of them became more and more cautious, and they soon approached the place where the battle was taking place.

Chen Chunan had already had this guess before, but when the facts were in front of him, he was still a little surprised.

These metal figures are very similar to the legendary mecha on the earth, but they are different from the mecha in Chen Chunan's understanding.

The energy that drives the metal people is the Yuan Force, and even the cannonballs they bombard are condensed from the Yuan Force.

But there were three green-haired monsters at once.

Li Ba said to Chen Chunan: "Those soldiers are the men and horses of the Grassland Tribal Alliance. ”

Chen Chunan suddenly said: "So, their secret army is a metal man?"

Even the soldiers of the Divine Army, when faced with an army of metal men, would be a one-sided slaughter, completely unable to resist.

It's like an army with cold weapons and an army with a fully armed hot weapon facing each other head-on, and it's not a heavyweight contest at all.

Thankfully, they didn't have to face such an enemy at this time, and there were even more powerful green-haired monsters fighting them.

With such a metal person, even a powerhouse in the Spirit Realm like Zhang Ruochen has to retreat, and it is difficult to match.

If the secret weapon of the Grassland Tribal Alliance was these metal men, it would be a disaster for the Shence Army and the entire Eastern Earth Divine Prefecture.

The person driving the metal man was just a monk at the peak of the Yuan Devouring Realm, but he was able to burst out with powerful energy that far surpassed that of the beginner powerhouse of the Imperial Spirit Realm.

The six powerhouses of the early level of the Imperial Spirit Realm were all injured to varying degrees, and even the two regimental captains were also wearing colors, and they were cooperating with the three mechs to attack the green-haired monsters.

Although the green-haired monster killed many soldiers of the Grassland Tribal Alliance, the injuries on their bodies were also very serious, especially one of the green-haired monsters had a broken leg, and its movement speed had obviously decreased a lot, and under the pressure of one of the regimental captains, even the ordinary cannonballs fired by the metal man mecha could not dodge.

"I'm keeping an eye here, and by the way, I'll record the battle data of the metal men, and you guys will pick up Lao Zhang and them. Cao Gui turned on the battlefield recorder on his armband and lay on the ground quietly observing the battle ahead.

"I'm afraid that the number of men and horses of the Prairie Tribal Alliance here is enough for three brigades. Cao Gui said.

"I'm afraid it's more than that. Li Ba shook his head and said: "Look at the corpses on the ground, originally they should have two regiments of men and horses, but now there is only one group left, and among the men and horses of these grassland tribe alliances, there are two existences that far surpass the junior powerhouses of the Imperial Spirit Realm, they should be two regimental captains, and there are six junior powerhouses of the Imperial Spirit Realm, they should be six brigade commanders." ”

Li Ba's eyes were very keen, and he found several leading figures among these soldiers in a very short time.

One energy projectile after another shot at its chest, and a large amount of green liquid splattered out of its body, pouring onto the sand.

Laugh at!

The regimental captain of the Prairie Tribal Alliance descended from the sky with a scimitar in his hand, and slashed deep into the green-haired monster's left shoulder.

Half an hour later, Zhang Ruochen took all the remaining members of the Pioneer Brigade through the fog and stood in the desert again.

The ancient city was cold and sinister, but the world outside the city was even colder, and the black blood on Zhang Ruochen's chest was quickly frozen into ice slag.

The battle between the Prairie Tribal Alliance and the Green-Haired Monster has not stopped, and the Green-Haired Monster, which had lost a leg, is nowhere to be found, and it is on its knees on one leg, completely unable to dodge the energy bullet attack on the metal man mecha.

The regimental lieutenant was very decisive, he raised and fell with a knife in his left hand, and slashed it with one sword, and half of his arm fell to the ground.

Hiss!

"This, the green-haired monster is so terrifying?"

A stream of green blood erupted from the green-haired monster's shoulder, and the regimental lieutenant with the scimitar was unable to dodge, and a few drops of green liquid landed on his right hand.

His entire palm immediately froze at a visible rate, and quickly spread across his arm.

Laugh at!

Through the footage transmitted by Cao Gui's battlefield recorder, many soldiers of the Pioneer Brigade gasped.

The strength of the green-haired monster is much more terrifying than that of the dry corpse, and the green blood on its body alone is terrifying, and even the strong people who have already broken through the spirit realm for many years cannot resist, and they need to cut off their arms to stop the spread of the freeze.
