The outermost walls of the Iron City were about a hundred meters high and nearly thirty meters thick, and the bricks on each wall weighed more than five tons, and the whole city looked the reddish-brown color of iron oxide from the outside.

The sky was still covered by thick radioactive clouds, and the humans on the ground seemed so small.

With a "boom" sound, the nearly 100-ton jack gate of the city gate was hoisted, and then, a convoy slowly drove out of the steel city.

The convoy consisted of more than a dozen heavy trucks carrying oil drilling equipment destined for Hope City, as well as some rare metals and monster materials.

Most of the trucks in the convoy are empty and are spare cars, and the truck drivers in the convoy are also ready to die at any time, and they have prepared suicide notes before going out!

As the back of the convoy came out more than 500 soul beings wearing mechanical armor and holding various weapons and shields, heavy mechanical armor and neat steps, making them let out a "thump" when they walked. Boom... Boom... Knock ......" dull rhythmic sound.

The last to come out were ten rune powerhouses, all of them were wearing mechanical armor, and the weapons in their hands were all bronze rune swords, their gait seemed random, but each of them had a strong aura and a faint coercion.

At this time, on the high reddish-brown city wall, Hua Yan, Han Chenggang, Shi Yushan, Hong Zhan, Shi Feng, Luo Zhongfa and several others were standing solemnly.

"Uncle Han, let's go."

Hua Yan looked at Han Chenggang with a respectful face and said softly.

This old man is much older than when he first came to the Steel City, and his back is also hunched heavier, and the survival pressure of nearly two million people has made him carry a huge mountain.

"Hmm!"

Han Chenggang didn't say anything, he agreed in a thick nasal voice, looked at Hua Yan kindly, and gently patted Hua Yan twice on the back with one hand.

"Daddy!"

Shi Feng was also saying goodbye to Shi Yushan.

The eyes of both father and son were a little moist, Shi Yushan's lips trembled a few times, and he gently stroked Shi Feng's shoulders and said:

"The Shi family has no seeds! Go, you've grown up too, kill it, and kill a piece of the world for humanity! ”

"Hmm!"

Shi Feng nodded heavily, gritted his teeth, but a teardrop accidentally rolled down, and he hurriedly turned his head and reached out to wipe it away.

Hong Zhan solemnly gave a military salute to Han Chenggang, Shi Yushan, and Luo Zhongfa, without speaking, and the three of them also silently returned the military salute.

Then Hua Yan, Shi Feng, and Hong Zhan flew down from the city wall and merged into the marching convoy in front.

Some time ago, with the help of his family, Shi Feng also constructed the "Ze" character script, and also became a powerhouse of double runes, but the newly constructed rune was still faint white, and he needed to continue to cultivate and strengthen.

The trio quickly swept past the convoy, walked to the front of the line, and began to make their way in the direction of Hope City.

Less than thirty kilometers out of the Steel City, he had already reached the edge of the Demon Beast Forest, which made Hua Yan secretly frightened, but he didn't expect that during this time, the scope of the Demon Beast Forest had expanded again!

Hua Yan remembered that when he came to the Steel City before, there were no such blue-black deformed vegetation here, but he didn't expect it to expand to this point in a month or two.

There is a heavy shadow in my heart, be fast! You have to kill these monsters quickly and destroy these monster forests!

After a while, these demon beast forests can even expand to the gates of the Steel City, and I really don't know what kind of difficult situation it will be at that time......

"Hong Zhan, turn on the over-the-horizon life detector, strengthen vigilance, let everyone rest first, and prepare to enter the demon beast forest."

Hua Yan beckoned over and Hong Zhan said.

"Good!"

Hong Zhan agreed, then turned around and made a stop and rest gesture to the convoy behind. Then he turned on the over-the-horizon life detector and began to monitor the surrounding environment.

At this time, Hua Yan, Shi Feng, and Hong Zhan had also put on mechanical armor, and the mechanical armor on the three of them was the kind of higher strength made before the end of the world, of course, this kind of mechanical armor also had higher requirements for people's bodies.

Hua Yan held the one-meter-eight long Wind Spirit Blood Sword in one hand, and was on guard, Shi Feng and Hong Zhan also took out the rare alloy rune sword that Hua Yan had created for them.

After resting for more than half an hour, the convoy began to slowly enter the demon beast forest, and everyone's hearts became nervous.

The deformed trees in the Demon Beast Forest were unusually tall and hard, and the blue-black canopy also obscured most of the sky, causing the light to be very dark.

If Hua Yan is alone, he has perception, and if his vision is not good, the impact is not too great, but it is different for other people in the team.

Now it's a convoy, carrying important supplies, and it's moving slowly.

As soon as I entered the Demon Beast Forest, sporadic demon beasts began to discover the convoy. and launched an attack, but these small number of B-level and C-level demon beasts, they did not deliberately avoid them.

A few rune powerhouses who followed took turns to fight, and they were slaughtered after dividing five by two, and the convoy suffered almost no losses, but instead made some demon beast materials.

But everyone didn't relax, and they all knew in their hearts that they had just entered the Demon Beast Forest for two kilometers.

In this way, the whole convoy had entered the Demon Beast Forest for nearly ten kilometers.

A fishy smell began to fill the air, and bursts of pale blue mist began to float between the blue-black misshapen trees.

Hong Zhan, who was in front of the team, suddenly raised his hand and made a gesture to stop all of them.

The entire convoy immediately came to a halt and fell silent.

"Quack~quack~"

There were a few piercing cries from the sky, this crow-billed dove is a kind of demon bird, with a pair of sharp claws, which can scratch through metal protection, and the cry contains a faint spiritual attack, touching the soul, a large number of crow-billed corpse doves chirping together can make people go crazy and kill each other.

"Director Hua, come and see!"

Hong Zhan was a little nervous and put the screen of the over-the-horizon life detector over.

Now this over-the-horizon life detector has a larger perception range than Hua Yan, so Hua Yan simply put away his perception to save soul energy.

Hua Yan looked at the screen handed over by Hong Zhan, his brows were also furrowed, in addition to the three crow-billed corpse doves in the sky, there were two dragon-scale demon pigs and more than a dozen iron-backed demon wolves around him moving quickly in their direction.

The dragon scale demon pig is an A+-level demon beast, when he first came to the Steel City, he and Shi Feng also worked together to kill one, and he is relatively clear about its strength, the iron-backed demon wolf is an A-level demon beast, and the last time Shi Feng suffered a plot, it was when he was fighting with a lone iron-backed demon wolf.

Their convoy was moving slowly, and it was impossible to avoid it, in this case, there was only one word - kill!!

Hua Yan's eyes gradually sharpened, and he shouted:

"All soul powerhouses line up to protect the convoy!"

"Hong Zhan, Shi Feng, wait a while, each of you will fight a dragon scale demon pig!"

Speaking of this, Hua Yan beckoned the ten rune powerhouses again and ordered:

"You guys are ready to take on the ironback demon wolf!"

"Yes!"

Everyone agreed in unison.

After the arrangement, Hua Yan, who was dressed in mechanical armor, was on guard with the Wind Spirit Blood Sword in his hand, but the three crow-billed corpse doves in the sky did not pounce down, but circled in the sky.

Hua Yan did not act rashly, he had to pay attention to the situation of the whole team at any time, and he didn't want to cause unnecessary harm to others because of his attack.

After about two minutes, I just listened to the "Whoa... Whoa..."Two five- or six-ton dragon scale demon pigs collided like roaring chariots.

Many of the blue-black misshapen trees in the impact path were also broken by the tremendous force of the impact.

Hong Zhan and Shi Feng jumped up almost at the same time, each rushing towards a dragon-scale demon pig.

"Woo~Woo~"

At this time, more than a dozen iron-backed demon wolves also surrounded him.

"Up!"

Hua Yan waved his hand.

The ten rune powerhouses standing beside him wearing mechanical armor and holding rune weapons all rushed out quickly and fought with these iron-backed demon wolves.

Hong Zhan and Shi Feng have both constructed the two runes of "Wind" and "Ze", and they themselves also have a strength of more than 3,000 kilograms, and with the strength bonus of more than 3,000 kilograms of mechanical armor, it is not too much of a loss to the dragon scale demon pig.

It's just that the fighting styles of the two are very different, Shi Feng is relatively light and elegant, and the Shi family's wind splitting sword technique is also quite unique, Shi Feng surrounded the alloy rune sword in the hand of the dragon scale demon pig and shining, leaving sword marks on this demon beast at a very fast speed.

Now Shi Feng's strength was enough for him to cut through the skin of the dragon scale demon pig, and after a while, blue-black blood began to splash everywhere, and after the dragon scale demon pig was in pain, he began to let out a crazy scream, staring at Shi Feng with blood-red eyes and repeatedly twisting his body with long fangs.

However, Shi Feng's speed was extremely fast, and the attack of the dragon scale demon pig basically did not touch the armor on Shi Feng's body at all, although the dragon scale demon pig had the ability to repair the body, but it could not withstand the slashing of Shi Feng's sword, and the momentum slowly weakened.

On the other side, Hong Zhan is another style of fighting, he now mainly uses the Mojia swordsmanship, but every move on him seems to be powerful and heavy, majestic and heavy, and a pure hard-hitting style.

At the beginning of the battle, the dragon scale demon pig rushed over from a distance, carrying tens of thousands of kilograms of impact, but Hong Zhan did not dodge or dodge, standing in place.

When the dragon scale demon pig was about to approach, Hong Zhan's mechanical armor left hand suddenly showed a big iron fist, and a "bang" punch hit the dragon scale demon pig's jaw, directly distorting the impact of the dragon scale demon pig, and deformed the mouth of the dragon scale demon pig, bursting out of blue-black blood.

Then he poked the sword with his right hand, and went down with a "poof", poking a hole nearly half a meter deep in the dragon scale demon pig.

If it weren't for the dragon scale demon pig's rough skin and thick flesh, and its extremely strong anti-strike energy, it might have turned out to be the result of it.

Seeing that Hong Zhan and Shi Feng both had the upper hand, the corners of Hua Yan's mouth curled slightly, and he put down the newcomer.

And the other ten rune powerhouses who were fighting with the iron-backed demon wolf were not as easy as Hong Zhan and Shi Feng now, the iron-backed demon wolf was very fast, and its claws were extremely sharp, tearing through their mechanical armor from time to time, causing trauma.

What's even more troublesome is that these iron-backed demon wolves obviously have a high IQ, and they also have strong organization and coordination, and they are more difficult to deal with when they work together.
