On the way to the temporary headquarters, the artillery positions did not stop firing.

Song Xirui also calmed down when he walked on the road, he knew that the artillery fire had not stopped, which meant that the two sides had not yet entered the stage of hand-to-hand combat, otherwise these artillery would have stopped firing a long time ago.

Approaching the front-line position, this place is far away from the artillery position, but it is a little quieter than the rear, looking at the defense line built with flesh and blood in the distance, Qin Shi'an said that it was a lie not to be moved.

It is because of these people that there is hope for humanity.

"Report!"

Walking to the temporary headquarters, Song Xirui shouted a report.

"Come in!"

After getting permission and letting the guards at the gate let them go, Song Xirui took Qin Shi'an and the three of them into the temporary headquarters.

Brown Sugar and the others were left outside the temporary headquarters by Song Xirui.

Seeing Song Xirui come in with three people, Song Guoqiang realized that this might be Qin Shi'an and others.

"Hello, I am the commander of the 9779 Army, Song Guoqiang, you are Qin Shi'an, right? I can call you Xiao An, right? Thank you for saving my son's life. Song Guoqiang greeted him, stretched out his hand to hold Qin Shi'an, and said words of thanks in his mouth.

Qin Shi'an wore a battle weapon, the characteristics were very obvious, and it was easy to recognize.

"Commander Song is polite, you are an elder, how you call it casually, it doesn't matter. As for saving Xiaorui, I also happened to be at the right time, and it was right to help my own kind. Qin Shi'an was a little flattered.

It was the first time Qin Shi'an had seen this kind of official, and he didn't seem to have much of a fight.

"These two next to you are your little brothers, right?" After greeting Qin Shi'an, Song Guoqiang's attention turned to Qian Haoduo and Hua Mantian behind them.

The two of them, Song Guoqiang, also knew that Qin Shi'an taught them the conditions for cultivating the body refinement, and Song Xirui had already reported it to Song Guoqiang in advance.

"Yes. Qin Shi'an replied.

"Hello chief. ”

"Hello chief. ”

Qian Haoduo and Hua Mantian were very self-aware, they could only enter here with Qin Shi'an's light, so they didn't come up to shake hands with Song Guoqiang, but bent down and half-bowed to say hello.

"Good, all right. Song Guoqiang said kindly.

"Father, the video has been recorded, how many levels of file should it be set?" Song Xirui saw that they were almost there, so he interjected a sentence.

"Xiao An, can you tell me how strong the effect of your exercise is?" Song Guoqiang did not answer Song Xirui's question immediately, but instead asked Qin Shi'an a question.

"The Basic Body Refining Body Determination can improve the physical fitness of ordinary people by about three or four times, and the Demon Tiger Body Refining Body Determination can improve the physical fitness of ordinary people by about six or seven times. Qin Shi'an thought for a moment and replied with an approximate value.

Song Guoqiang was very puzzled when he heard it.

"Xiao An, according to what you say, even if humans practice to the limit, they can't beat the black devil, right?" Song Guoqiang said his doubts.

"Cultivation is not a simple method of addition and subtraction, there will be many factors involved, the first important factor is the level of physique, you can understand the quality of qualifications. If you compare a normal person to 10, then some people can reach the sky if they can go up to 100 when they cultivate, but some people can go up to 1000 when they cultivate, and this is the difference between high and low physique. Qin Shi'an explained Song Guoqiang's doubts a little.

"Oh, I see. After listening to Qin Shi'an's explanation, Song Guoqiang realized that cultivation really had good qualifications.

I used to think it was a novel, but I didn't expect it to be like this.

"Is there a way to tell if everyone's physique is high or low?" Song Guoqiang thought for a while and asked another question.

"I can't screen this, so I can only let everyone judge the level of physique by looking at their data after cultivating. "In the other world, it is all data automatically displayed by the system, and Qin Shi'an himself has no way to measure the physical fitness value of others.

"In this case, let's make it an S-class file first, and send it to the logistics archives department for preservation. Hearing that there was no way to screen qualifications, Song Guoqiang didn't bother too much, and first set the level of the file.

"Yes. Song Xirui responded.

"Father, Brother Qin said that he can close the space tunnel. Song Xirui saw that they had finished talking about the exercises, and hurriedly told Qin Shi'an that he could close the space tunnel.

"What ??!!"

Hearing Song Xirui's words, all the officers in the temporary command headquarters came over, this news was really amazing!

"Xiao An, do you really have a way to close the space tunnel??!!" Song Guoqiang asked excitedly.

He couldn't help but be excited, cultivating exercises and fighting monsters is just a palliative way, even if you cultivate to the point where you can defeat the black devil today, you don't know if there will be monsters stronger than the black devil in the space tunnel one day.

Now he suddenly heard that Qin Shi'an could close the space tunnel, this is the way to cure the root cause, how could Song Guoqiang not be excited!

"As long as you can find out where the space tunnel is, shutting it down shouldn't be a problem. ”

With the jammers provided by the system, closing the space tunnel is not a problem.

"Okay! great! I'll ...... right away."

Just as Song Guoqiang was excited to say something, a shout in the temporary headquarters interrupted him.

"The monster is about to come within range of the ground forces!" a soldier in charge of monitoring where the monster was attacking suddenly shouted.

"What! so fast!" Song Guoqiang didn't care about anything else, and immediately walked behind the soldier.

The screen on the monitor can already put both the enemy and the enemy inside, which means that the distance between the enemy and the enemy is very close!

As you can see from the screen, the first to rush over are low-level monsters such as the white bone skeleton and the green-eyed walking corpse, and the ghouls are blocked behind them due to the focus of the artillery, and they can't rush for the time being.

That particular ghoul had been pressing behind the monster tide and hadn't rushed up.

Such a result made Song Guoqiang breathe a sigh of relief, and the artillery still played a certain role.

“10，9，8...... 1！”

When the soldier's countdown reached 1, gunfire erupted outside the temporary headquarters!

Dada......!!!

The rapidly surging monster tide collided head-on with a metal frenzy, and the furious metal frenzy tore the monsters rushing ahead to shreds!

The monster tide has been suppressed!

Between the enemy and the enemy at a distance of 100 meters, they are competing for space for survival, and the human defense line is in danger.

In particular, the deadliest ghouls are about to break through the artillery blockade.

In the temporary headquarters, everyone held their breath and nervously watched the battle situation on the screen.

"Ready to reload! The second row is ready to take over from the first row!"

"Ready!

In front of the position, the soldiers of the two teams quickly exchanged positions, the soldiers of the first row retreated and changed the ammunition, and the soldiers of the second row stepped forward to take over the defense line, maintaining a state that there was always a rain of bullets suppressing the monster forward!

"Don't be afraid, the monsters in front of you can be killed with bullets, they are not invincible!"

The officers in the army were constantly cheering on the soldiers behind the soldiers, so that they would not be frightened by the horror of the monsters.

A large number of white bone skeletons and green-eyed walking corpses were shattered in this torrent of metal, and the distance of 100 meters, which normally only took a few seconds, was now as impassable as a moat for them.

"Molotov cocktail ready!"

"150 meters ahead!"

On the long front, some places can no longer withstand the pressure of the monster's advance, and they began to use the unconventional weapon of incendiary bombs, which ignited a sky-high fire behind the monsters, forming a wall of fire, although the wall of fire only eased the monsters' offensive momentum slightly, but also allowed the soldiers on the front to regroup and suppress them again.

"Let the artillery in the rear wash 200 meters in front of the front line, right?"

"No! The artillery is now suppressing the black devils, and there is no way to draw fire to support us!"

In front of the battle line that is more than ten kilometers long, it is densely packed with monsters, although there are more than 70,000 soldiers in the human race holding their positions, but the number of monsters is even more!

There are all kinds of situations happening on the battlefield all the time, and the slightest problem in these situations can make the monsters take advantage of the situation to break through the human defenses.

If the monsters get close to each other, then the humans will have no chance of winning.

Inside the temporary headquarters, a loud voice suddenly broke the silence!

"The Dark Devil has broken through the artillery blockade!!The Black Devil has broken through the artillery blockade!!"

The soldiers, who had been keeping an eye on the ghouls, gave a sharp report on the ghouls' breakthrough through the artillery blockade.

Except for Qin Shi'an, the faces of all the people in the temporary command turned pale.

No one knows better than them what the deadly consequences of the Dark Devil breaking through the artillery blockade will be.

The weak balance on the front of you will be shattered in an instant under the impact of the black devil!

At that time, countless soldiers will be killed.

Song Xirui didn't say a word, turned around and rushed out of the temporary headquarters.

"Xiao Rui!"

Song Guoqiang, who was awakened by Song Xirui's actions, was too late to stop him.

"I'm going to bring him back. Qin Shi'an said a word to Song Guoqiang and then turned around and prepared to go out.

Qian Haoduo and Hua Mantian were also ready to follow Qin Shi'an out at this time, but they were stopped by Qin Shi'an.

"Neither of you are soldiers, you can't even use a gun, and I'll have to spend energy protecting you when you go out, so you better stay here." ”

After listening to Qin Shi'an's words, Qian Haoduo and Hua Mantian couldn't object, because they really couldn't help if they went out.

"Commander Song, my two brothers will ask you to take care of me, Xiaorui I will bring it back. After talking to the two brothers, Qin Shi'an turned his head and entrusted Song Guoqiang.

"Okay, no problem, the two of them will stay with me. Song Guoqiang nodded and said that he would let them stay with him.

"Thank you. ”

After Qin Shi'an finished speaking, he patted the shoulders of the two dead friends and walked out of the temporary headquarters.

Out of the temporary headquarters, Qin Shi'an looked around and found that Song Xirui had already run a hundred meters away.

Brown Sugar and the others, who were waiting outside just now, also followed Song Xirui to the battlefield, and the video recording machine was placed in a corner outside the temporary headquarters.
