Chen Bai's whole body was ignited with golden flames, and he punched the dog-shaped mutant beast with five heads. The high temperature exploded and knocked its huge body into the air.

Roar!

This mutated beast was extremely ferocious. It was at high altitude, and it actually twisted its body forcibly. When it landed, it aimed its mouth larger than a truck at Shen Bai, and smashed its fangs on his body.

"snort……"

Shen Bai put his hands on his head, holding the fangs that were more than two meters long. The golden flames flowed to his arms. He used brute strength to continuously lift the five giant dogs like breaking sacks and hit them against the steel house. .

The already crumbling building was torn apart. After everything within a hundred meters radius was razed to the ground, the giant dog whimpered and stopped breathing.

Shen Bai gasped, and the golden flames on his body flickered.

The Apocalypse also needs to rest. After a long and fierce battle, Shen Bai's physical strength and energy have reached the limit. Otherwise, it only took half a second to burn the five giant dogs into cokes.

This was the sixth hour after the main force of the expeditionary force had evacuated, and all the people behind had entered a state of street fighting.

The Steel Fortress is too high and too wide, blocking the beast tide like a city wall. You can only climb in and then out.

After releasing all the large-scale thermal weapons in their hands, the troops hid in buildings, laid mines, and sniped at the mutant beasts and aberrations that entered.

Due to the "current limiting" effect of the Steel Fortress and the tenacious fighting of the Duanhou troops, the beast tide has been advancing extremely slowly. Although occasionally strong men break through the defensive line, it is not harmful. The Duanhou troops have left sufficient gaps for the larger forces. time.

However, the price is also very high.

Just as Shen Bai had thought before, a large number of wounded soldiers in the Duanhou army were slaughtered immediately after squandering their ammunition. Today, only about 5,000 people are still fighting tenaciously in street fighting.

This number will decrease every minute, and as the number of humans in the Steel Fortress decreases, the number of mutant beasts breaking through the defense line and chasing them forward will increase. In a dozen hours, the rear of the main body of the expeditionary force will be Enemies from the old land have appeared.

But that is inevitable. Shen Bai and his team's mission is to seize the rear. Just buy time. There is no need to fight to the death. Once twenty hours have passed, the surviving retreat troops will hide in underground bunkers where there is sufficient fresh water and food. , and even has a very good drainage system, where people can wait with peace of mind for the expeditionary force to come back again.

Of course, the premise is that you can survive.

Two hours later, the golden flames on Shen Bai's body were so weak that he couldn't even let the temperature of the flames rise. He could only spread the golden flames into a very thin layer, covering the surface of his body.

Another hour passed, and Shen Bai's flames decreased again. After being dragged twice by mutant beasts and smashing a house, he removed the flames covering most of his body, only supplying his limbs to maintain mobility and lethality, and once again Kill back.

Nine hours after the street fighting began, Shen Bai could no longer see his comrades around him. Everything he could see was blood and mutilated corpses. All the steel and concrete houses collapsed and turned into ruins.

He has now changed his tactics again, focusing on fighting and harassing, and will never fight head-on as a last resort.

Ten minutes ago, he saw Liu Tiancang. This guy who was known as the number one high school student in Lanhai City looked worse than him. He looked like a bloody man, with his whole body covered in red. Shen Bai was about to say hello when he saw Liu Tiancang screamed and jumped into the belly of a huge mutant beast. After a few dozen seconds, he used ferocious combat skills to disembowel the belly from inside, tearing the mutant beast's body apart and then jumped out, still covered with various colored internal organ fragments. .

Then in the blink of an eye, he was swallowed by another mutant beast.

Shen Bai, who was far away on the other side, gritted his teeth. It seemed that Liu Tiancang was too tired and could only use this stupid method.

As for Fenghua Rei, although this girl is suffering from the disease of heaven, as long as the battle starts, she will use her [Mimicking God] to bombard her wildly. She suppresses the most enemies in the center of the steel fortress.

Another two hours passed, and the sounds in the Steel Fortress became smaller and smaller. Now, most of the mutant beasts would not be effectively blocked. They roared through here and chased in the direction of the large army.

There were only about 2,000 people left after the break, and they were all gritting their teeth to hold on, stuck in place like nails.

However, because there were too few people left, out of proportion to the mutated beasts, this group of ferocious beasts only focused on chasing the retreating troops, but there was not as much pressure as at the beginning, and because the people who were still alive were at least little masters, those who died in battle The speed has slowed down somewhat.

When Shen Bai was blown away by a certain mutated beast, he leisurely observed it in the air and felt that when the mission was over, there would probably be about a thousand people left alive in the fortress.

The survival rate is one tenth. Although the cost is high, the mission has been successfully completed, which is much better than being wiped out.

"Attention everyone, if we persist for another four hours, we will be able to enter the underground bunker. Please leave enough energy to retreat in time!"

During the selfless battle, Zhou Yulin's panting voice came from the micro headset. Shen Bai breathed a sigh of relief, swallowed a high-concentration psychic meatball into his belly, and regained his strength.

This is a special military ration that can only be provided by second lieutenants and above in the army. It is a product of Hercules Company. It not only contains high concentrations of psychic energy, but also stimulants and analgesics.

Shen Bai counted the time and planned to swallow one pill every hour during the next period, hold on until it was time to retreat, and then run away.

He felt that he had done enough for this war and there was no need to risk his life and die in the fortress.

He has no self-destructive tendencies and would be best off alive.

However, just a few minutes after Shen Bai swallowed the special military rations, he suddenly caught sight of a handsome young man from the corner of his eye.

He was sitting on a tiger-shaped mutant beast, wearing blood-stained fur and looking stern.

——It is boundless tyranny!

Shen Bai was stunned for a moment, and the next moment, a strong will rose in his heart.

It was this guy who launched the invasion of Lanhai City, causing more than 200,000 expeditionary troops to die in the underground world. He was the culprit and a core figure on the Old Earth side!

The fatal injuries caused by the guardian cannot be healed in such a short period of time. Wujiang Tyranny must be forcibly suppressing it at this time. It seems strong, but it is actually the weakest time!

An unstoppable murderous intention arose in Shen Bai's heart. The enemy's leader was rarely alone, and his combat power was horribly reduced. This was a great opportunity to kill him.

"Hello...Brother Liu?" Shen Bai clicked on the headset and adjusted it to the private channel:
Chapter completed!
