High Martial Arts: Slay enemies to become stronger, forge invincibility from billions of corpses.

Song Chen sheathed his sword, staggered a step, and knelt on one knee against the outer wall.

Zefar released the gun from his hand, took two steps back, looked at the two halves of the corpse, and then turned to look at Song Chen.

Gu Tu lay not far away, unable to stand up.

Zefar said, "Let's go to the command center; there are two more there."

Song Chen stood up, walked to Gu Tu's side, and glanced down at him.

Gu Tu was covered in wounds; the cannon barrel on his right arm was shattered into three pieces, and half of his faceplate was nowhere to be found.

Song Chen tried to help him up, but Gu Tu waved his hand and said, "Go away. If I can't hold the command center, then my injury will have been for nothing."

Song Chen didn't say anything more and turned to fly back to the defensive line.

The road ahead will be fought for.

When Song Chen returned to the interior from the outer wall, the battle inside the defensive line had reached a fever pitch.

The enemy deployed a large number of troops in every direction, but their most elite forces were all concentrated on the road leading to the command center.

As soon as Song Chen entered, he was met with a swarm of Blood-Corroded Battle Bodies, which were as dense as ants. The sixth and seventh-tier enemies rushed towards the core area like madmen.

He had no time to hesitate; he gripped the knife and charged in.

The Void Traveler became the most terrifying weapon in the chaotic battlefield. Every time he appeared, he landed precisely in the densest area of ​​enemies, and the Star-Splitting Slash's momentum was unleashed once again.

Wherever the blade flashed, hordes of enemies fell, as if harvested by an invisible scythe.

He led an ever-growing number of Allied soldiers behind him, like a sharp dagger piercing straight into the enemy's heartland.

"Follow that silver-armored man and kill!"

"Don't fall behind, he's too good!"

"That swordsmanship... I couldn't even see the shadow of his blade!"

……

Song Chen ignored what was behind him; his attention was entirely focused on what was in front of him.

The command center was just a few hundred meters away, and the severely deformed alloy door was still stubbornly holding on.

Two eighth-level auras were not far behind the door, like two balls of energy that could explode at any moment.

Song Chen accelerated, weaving through the enemy lines, his blade flashing incessantly.

One after another, the Blood-Corroded Battle Bodies were cleaved in front of him, and his kill count soared at a visible speed.

He had killed so many that he couldn't even remember them all. All he knew was that the road was littered with corpses, enemy and friendly, all mixed together, indistinguishable from one another.

His silver armor was stained with blood—red, green, and black—making him look like a demon crawling out of a sea of ​​blood.

"Support, support has arrived!" Virian's voice suddenly came through the communication channel.

Song Chen looked up and saw dozens of powerful auras approaching in the starry sky outside the defensive line.

The leader's aura was extremely strong, even stronger than Zefar's.

At the same time, signs of spatial teleportation appeared inside the defensive line.

The reinforcements for the Tian Shu defense line have finally arrived.

The remaining two eighth-tier warriors of the Blood Erosion Civilization reacted almost simultaneously, retreating with their troops without hesitation.

The biological fleet retreated from the defensive line like a receding tide. Song Chen didn't give chase. He knew he couldn't catch up, and there was no need to.

He stood at the door of the command room, panting heavily.

The kill count in the lower right corner of the system panel was lit up. He glanced down at it and saw it was 580 billion.

The battle did not last long, but its intensity was unlike anything he had ever experienced in his life.

He turned his head to look at the huge hole in the defensive line, then looked at the dilapidated corridors and the corpses scattered all over the ground behind him.

"The enemy has retreated," Virian's voice came from the side, hoarse with relief.

"They didn't retreat; they just withdrew. They'll come back from millions of kilometers away."

Vilian gave a wry smile and nodded.

Song Chen sheathed his knife, turned and walked towards a relatively intact corner; he needed to rest.

He went to a corner and sat down with his back against the wall.

I closed my eyes, but I couldn't find peace and quiet.

Everyone along the entire defensive line seemed to have heard about the battle that had just taken place. People would occasionally pass by, glancing over before quickly looking away.

Two iron soldiers stopped directly in front of him, pushing each other. Finally, one of them was forced forward by his comrade, awkwardly saluted, and then ran away quickly.

After a while, several gunmen from the Huiyang Civilization stood in a row at a distance, bowing slightly in their direction as if to express their respect.

Song Chen kept his eyes closed; he felt it was pointless.

Soon after, Zefar came over.

He was still wearing the officer's armor, which was dented and battered from the battle, with several deep knife marks on his breastplate, left from a head-on clash with the short, stocky man.

The golden spiritual energy had been withdrawn into the body, leaving only a faint glow covering the skin's surface.

As he walked, soldiers kept saluting him, and he smiled and nodded in response to each one, not at all like someone who had just finished a life-or-death battle.

Zefar sat down opposite Song Chen and said in a hoarse voice, "I can't sleep. After killing eight-level people, not many people can sleep."

Song Chen opened his eyes and looked at Zefar: "I wasn't planning on sleeping. How's the defense?"

"We're still taking stock. The command post has been saved, and the core area hasn't been breached, but the damage rate of our outer defenses has exceeded 70%."

"Your killing of that eighth-tier enemy was decisive for the entire battle. If he had survived and fought his way to the command center, we wouldn't have been able to hold out until Tian Shu's reinforcements arrived."

Zefar continued, "I've lived for tens of thousands of years, which is considered long in my race. But in these tens of thousands of years, I've seen countless seventh-tier beings, and there are only a handful of them who can fight eighth-tier beings."

"You're the first seventh-tier being to kill an eighth-tier opponent."

Zefar spoke very seriously, without the slightest exaggeration.

"If I'm not mistaken, your swordsmanship has already reached the peak of the Star Crown level."

"And that teleportation ability, which can still be used under the spatial blockade of Tian Shu, is something I've only heard of in some ancient traditions."

"But you don't need to be nervous. It's nothing. Which strong person in the universe doesn't have secrets? Your strength is a good thing for our defense line."

Song Chen laughed and said, "Thank you for the compliment."

Zefar chuckled a few times as well: "Let's get down to business. The Joint Defense Council has approved the rewards for this operation."

"You single-handedly held off the East District and cooperated with us to kill the eighth-tier enemy. The command has given you the highest praise."

He reached into his pocket, took out a spatial ring, and handed it to Song Chen.

Song Chen took it and probed it with his mental energy. Inside was a large pile of cosmic crystals.

Zefar said, "This is 50,000 cosmic crystals. These are extraordinary times, so the reward will be given on the spot, without delay."

"These 50,000 crystals can be directly exchanged for military merits within Tian Shu, or for resources in the Warrior Shop. You should be able to use them if you need anything during your breakthrough later."

Song Chen accepted the ring.

Thank you.

Zefar stood up: "You're welcome. It was sent from above. Go take a rest. The next wave won't be too far away."

After Zefar left, Song Chen sat for a while longer.

He glanced down at his hands; today he had killed a genuine eighth-tier Star Crown Realm expert.

Although that strike had all the advantages of timing, location, and people—Zefal and Gutu were locked together at the cost of their lives, and the eighteen strikes of the Star-Splitting Slash were stacked to their maximum to succeed—it was still ultimately he who killed him.

A seventh-tier warrior killing an eighth-tier warrior? If word got out, no one in the entire Moonshadow Battle Zone would believe it.

The road ahead will only get harder, and he needs to toughen himself up before those even tougher roads appear.
