Even a one-star general should have respect for those who cover the rear, because they risk their lives to do so.

"Mission accomplished!"

At that moment, all fifty-three special operations squads saluted. On the battlefield, life and death are no one's fault but one's own. Once on the battlefield, one's life is no longer one's own.

However, Jiang Yuan sensed another power emanating from this one-star general. He stepped forward and looked at the middle-aged man, asking, "General, what is the situation at the front? Does Shiyan Pass still exist?"

If he had been asked this question by a lowly soldier who didn't even wear a military insignia before, he would have slapped him long ago. But the situation was different now, and he had to answer: "The Altai defense line has fallen, and the Nine Dragons Formation base at Shiyan Pass has begun to be moved!"

Jiang Yuan frowned. Only now did he dispel his doubts. If he guessed correctly, the power emanating from this one-star general was indeed the Nine Dragons Formation Base. That was why he had to send someone to cover the rear. The Nine Dragons Formation Base was related to the future of China. Let alone sacrificing a few special operations teams, even sacrificing the entire Fierce Tiger Legion was necessary to protect the Nine Dragons Formation Base.

"Let's retreat!"

The one-star general ignored Jiang Yuan and led the Tiger Legion, which had less than 20,000 men left, through Death Valley. This number showed that the Tiger Legion had indeed suffered heavy losses, losing one-third of its main combat force, and was theoretically close to losing its fighting capacity.

Watching the heavily wounded Tiger Corps retreat, the four special operations teams remained silent. This is war.

Once the entire Tiger Legion had withdrawn, Jiang Yuan shouted, "Blow up the exit of Death Valley and prepare to hold out for one hour!"

That's right, they had no other choice but to rely on the terrain of Death Valley to hold out.

Death Valley cuts through the Altai Mountains, and it is the only passage for the Holy Spirit Clan to reach the border of China. If they don't go through here, it will take the enemy at least several more days to cross the Altai Mountains and enter western China.

Death Valley has a unique structure with a treacherous terrain that makes it difficult for even one person to pass through. This is why the higher-ups allowed the four special operations teams to stay behind, because they had found a good place for themselves.

"Aren't you leaving any way out?" Lin Yu hesitated when he heard Jiang Yuan's crazy idea.

If the exit of Death Valley is blown up, they will truly be isolated and helpless with no way out.

“If we can’t stop them for an hour, the Tiger Legion will lose five figures!” Jiang Yuan said in a deep voice.

Fifty-three deaths and five-figure deaths may seem like a comparison of numbers, but for those who are personally involved, it's more than just a comparison of numbers.

"Let's blast it!" Zhang Chong, the captain of Team Seven, agreed with Jiang Yuan's plan.

"I agree!"

"I agree!"

Apart from the captain of Team Seven, the captains of Team Twelve and Team Eighteen also agreed with Jiang Yuan's do-or-die approach.

"Okay, explode!"

Lin Yu finally agreed, and there was no time to hesitate.

"Boom!"

With a deafening roar, a mountain several hundred meters high collapsed, completely blocking the exit of Death Valley.

Almost exactly ten seconds after the explosion, a force far larger than the previous Tiger Legion appeared.

"The Holy Spirit Clan!"

Jiang Yuan looked at the Holy Spirit Clan that appeared before him. He had never seen such a pure Holy Spirit Clan team before. The Holy Spirit Clan, which had not revealed its strength in the past, finally showed its fangs to dominate the battlefield after the battlefield was fully restored.

"A hundred thousand Holy Spirit Clan soldiers!" Jiang Yuan's pupils shrank. Humans had always been able to slaughter beastmen, but the Holy Spirit Clan was an exception. They were a group whose individual strength was even greater than that of humans.

“Not only that, they also have a beastman army of nearly a million behind them!” Zhang Chong shook his head and said.

This was a dead end; those fifty-three people couldn't possibly hold out for even an hour.

"Retreat to the narrow pass and don't let the main force in!"

Jiang Yuan realized at this moment that stubborn resistance was futile; they could only use the strategic advantage of the narrow pass to delay the enemy.

Without Jiang Yuan saying anything, the other fifty-two people knew what to do, so they immediately abandoned the advantageous terrain they had already occupied and retreated into Death Valley.

"kill!"

The leading Holy Spirit looked at Jiang Yuan with a ferocious smile. The order had been given from above to take the traitor's head, provided that there was some connection between them and the traitor.

The racial war is the cause and effect, and as long as Jiang Yuan dies in this war, the higher-ups will not blame him in the slightest.

The Holy Spirit Clan remained motionless, while countless spirit beasts behind them charged into Death Valley.

"Detonate!"

All the spirit bombs from the four squads exploded, shaking the entire Death Valley for a few seconds.

With a deafening roar, another section of the massive valley, stretching for dozens of miles, collapsed, not only killing countless spirit beasts but also temporarily separating the Holy Spirit Clan from the spirit beasts, buying Jiang Yuan and his companions precious time.

"kill!"

Within the narrow passage of the One Line Heaven, which was only ten meters wide, the spirit beasts could not rush in in large numbers. Jiang Yuan, however, transformed into a deadly vanguard, wielding the Gentleman's Sword and charging into the spirit beast ranks from the opposite direction.

"Sword Drawing Stance!"

"Directory-style!"

"Embracing the Moon Style!"

"Swallow Return Style!"

"..."

"Sword Killing Style!"

Jiang Yuan used the Thirteen Swords of Tai Chi to their fullest extent in this narrow space. Whether they were in the Void Spirit Realm or the True Spirit Realm, they could only perish under Jiang Yuan's ferocious attacks.

"Jiang Yuan, there are birds flying in the narrow sky!"

Ground-based blockades are not a panacea, because in the Spirit Realm, some creatures have already acquired the ability to fly.

A flash of lightning streaked across Jiang Yuan's dark pupils. He looked up and said, "You guys guard the narrow passage, I'll take over up there!"
