On the battlefield, the army of the Star Luo Empire was in chaos.

"Seventh Soul Technique! The Lion King's True Body!"

Wren directly abandoned his horse, turned into a wild lion, and rushed to the rear of the army at great speed.

However, it was still too late, and the rear army, as usual, completed the attack in the time of a stick of incense, and set a fire on the grain and grass.

And the attacker is customary, leaving the iron hoof prints of war horses on the battlefield of yellow sand.

Wren knew that even if he followed the hoof prints of these horses to track the traces of the enemy, it would be useless, and these hoof prints would disappear completely after a certain distance.

"Damn...... "Even if he has a good temperament, he will feel quite annoyed by being teased like this for a month.

The enemy is like this every time, coming and going without a trace, attacking the supply army of the Star Luo Empire, and they have no choice.

Although the number of escort supply troops has been increased this time, and even 10,000 Royal Knights of the Star Luo Empire have been dispatched, the enemy still found an opportunity to attack and kill the weakest part of the supply army.

The point is, the Royal Knights of Xingluo and he are also incapable of separating each other.

He had also tried to have the Royal Knights of the Star Luo Empire spread to every part of the supply army.

However...... The scattered knights of the Royal Knights of the Star Luo Empire couldn't stop the enemy's edge, but instead let that part of the Royal Knights of the Star Luo Empire send them to death in vain.

They lost hundreds of members of the Royal Knights of the Star Luo Empire for this.

Although they are the elite of the empire, the scattered elite cannot stop the surprise attack of the enemy army.

Because of this, Wren had no choice but to give orders that if he found an enemy army anywhere, he must immediately call out his allies.

And the other armies must go to reinforcements as soon as possible.

But it still didn't work.

Because after a small number of nearby reinforcements arrive, they will still be defeated by the enemy and killed together.

Moreover, the direction chosen by the enemy to attack must have been a long distance from Wren, and before Wren and the other main forces arrived, the enemy flew away.

That's the worst part.

Back and forth, Wren really had no choice.

This strategy of light cavalry wandering and attacking, coupled with the strange performance of the enemy coming and going without a trace, no one can do anything.

Even a peerless general like Ren who is famous in the entire Douluo Continent.

"General...... The enemy is gone again." One of the generals, the Imperial Horse, came to the golden lion that Wren had turned into and said, "This time we have lost about one-tenth of our grain, grass and baggage, and more than 8,000 casualties."

Wren's Lion King True Body frowned humanely, "I see."

Such casualties and losses are already commonplace.

Every time grain and grass was transported, it was attacked by enemy troops, followed by casualties and losses.

Not to mention Wren, even the army of the Star Luo Empire is used to it, and the tools to extinguish the fire have been prepared early, and this is an ancient battlefield filled with yellow sand, and the yellow sand is the easiest to extinguish the fire.

They took a shovel and scooped up a spoonful of yellow sand, covered it with the flame, and extinguished the fire.

But even so, every time a part of the grain and grass is lost.

It's just that they are skilled in extinguishing fires, and the proportion of losses is not as high as it was at the beginning.

The grain and grass transported back were lost, but they could still feed the army of the Star Luo Empire in Zhennan Pass.

"Take a break, and then we'll get ready to go back to the city." Wren lifted the martial soul true form, and finally said.

……

After returning to the mountain range, everyone in the Heaven Dou Royal Knights was full of smiles.

During the month of fighting, they were almost unscathed, not even a single soldier was killed.

Of course, injuries are inevitable, but after all, there are no casualties, and it is a blessing on the battlefield.

What makes them happiest is that they can

After killing the people of the Star Luo Empire's army and burning the grain and grass, he can still walk away.

Those cubs in the Star Luo Empire have nothing to do with him, this is the coolest.

There has been a long-standing grudge between the two empires, especially these soldiers, the longer they have been soldiers, the more they have fought with the Star Luo Empire, the more they hate the people of the Star Luo Empire.

This is the hatred that will inevitably arise between the two powerful countries, and the only reason they do not hate is because they have not had much contact.

"Presumably, the four kingdoms have retreated and gathered their troops at this time." Lu Yuan smiled and said, "It's already the twenty-sixth day."

"yes, almost another month has passed before I know it." Ning Rongrong also said with some emotion.

However, the month's battle led by Lu Yuan was far easier than the previous month's battle of holding Zhennan Pass.

During this period, he used the source number to control the portal and went to the territory of the Duchy of Hull to observe the situation of the Lu Po and them, and the guerrilla warfare of the Celestial Shadow Army was also good.

But compared to the Heaven Dou Royal Knights, although the battle situation on the side of the Celestial Shadow Army was good, there were not many casualties.

In particular, the army of the Star Luo Empire deliberately targeted and planned two battles of annihilation, and the Celestial Shadow Army lost more than 4,000 soldiers.

The Star Luo Empire was also ruthless enough, and directly set a fire in the jungle, and the fire stretched the entire forest where the Celestial Shadow Army was hiding, which forced the guerrilla scattered warriors of the Celestial Shadow Army out.

At this time, it was the end of August, and the sky was high and dry, and it was difficult to extinguish this fire.

In a world that was so developed in the previous life, the continuous summer and autumn wildfires were natural disasters that were difficult for humans to easily solve.

And even more so now.

Moreover, in this era, human towns and jungles are staggered and crisscrossed, which is closer than the location of human cities and mountains and forests in Lu Yuan's previous life.

The fire broke out, and it was able to directly burn down the city of Hull, where the Star Luo Empire's garrison army was located.

Therefore, the follow-up Star Luo Empire also paid a lot of pain to extinguish the mountain fire.

This is a self-inflicted loss of 1,000 and the killing of 800 enemies.

The Celestial Shadow Army can be regarded as a good completion of the essence of guerrilla warfare.

"yes, so General, are we going to continue fighting for the next four days?" Gao Kai on the side couldn't help but ask.

"Anyway, we've been playing with the Star Luo Empire for a month, and we've never officially met with them, so it's a bit unreasonable...... right" Lu Yuan smiled slightly at this time and said.

"General...... You mean......" Barnaby said at this point.

"They should have a huge amount of grain and grass coming over in the next four days, let's take advantage of this last battle to officially make a appearance with them......" Lu Yuan laughed softly, but a flash of wisdom flashed in his eyes.

Suddenly, everyone understood the meaning of Lu Yuan's words.

Lu Yuan, this is the last time to make waves for the Star Luo Empire.

But it was exactly what they meant, and they all excitedly responded, "Yes! General!"
