Before Ren Xiaosu set off on his mission, he had pulled Ji Zi'ang aside and whispered something to him. At the time, Wang Yun vaguely heard mention of the cesspit. So Wang Yun could vaguely guess at that time what Ren Xiaosu might be thinking.
By putting the tunnel and the cesspit together, it was very difficult not to associate it with something bad.
But even though everyone was mentally prepared, they still found it a little cruel when this indescribable scene happened.
The level of the cesspit rapidly decreased, taking only five minutes to drain to half its original level.
P5092 was speechless. He had been studying military strategy for more than 10 years, but this was the first time he saw someone doing something like that on the battlefield.
Ren Xiaosu was really willing to resort to anything on the battlefield to achieve victory.
Mt. Zuoyun was once again attacked by the expeditionary army's main forces. They saw the barbarians rushing over from the wilderness, and it looked like they were coordinating with the elite barbarians underground to carry out a pincer attack.
However, they were still unaware of the cruel things that would soon befall their elite warriors.
Wang Yun thought about it from the other perspective where someone used such a method against him. His scalp went numb.
Ren Xiaosu asked Xun Yeyu, "How far have those underground barbarians gone?"
"They're right over there and advancing quickly. I estimate they'll encounter the… within a minute," Xun Yeyu said as he tripped over his words. He really did not want to talk about it as it was a little gross.
Ren Xiaosu looked at Ji Zi'ang and pointed to a spot. "Over there, cut off their escape route there and leave a ventilation hole behind them."
"OK." Ji Zi'ang nodded and said.
Everyone understood Ren Xiaosu had never had any intention of letting the barbarians leave.
In the tunnel, Anatoli, who was at the front of the group, suddenly said, "I smell something strange!"
Anatoli was the "Crazy Bear" responsible for tracking Ren Xiaosu with his sense of smell in this group of elites. But just as he finished speaking, the barbarian behind him snapped, "Even without your sense of smell, we can smell the strange smell."
As they spoke, the barbarians nearly teared up from choking. It was not that they were crying from sadness but that the smell was too pungent!
"Retreat! Retreat!" Anatoli suddenly shouted.
Unlike what they had imagined, the enemy did not plant any bombs in the tunnel. Instead, they used an even more despicable method!
But when they wanted to turn around and return through the passageway behind them, they were shocked to discover that the path had been sealed off. All that was left was a ventilation hole only big enough to fit a thigh through!
The reason why Ren Xiaosu wanted Ji Zi'ang to leave an opening there was purely so that those indescribable things could get in easier.
By the time the barbarians realized the path behind them had been completely sealed off, they were getting devoured by a yellow torrent.
One of the barbarians immediately commanded, "Break open the ceiling of the tunnel. We're very close to the surface now, so we should be able to open up a path to the top… glugurgh…"
When the other barbarians heard the drowning sound this comrade made, they nearly vomited.
However, they were not much better off. When one of the barbarians saw the yellow torrent had already reached his thigh, he immediately hit the soil layer above his head with everything he had.
With just one punch, the soil layer started to loosen up a little. "Quick, let's hit the soil layer above our heads together… glugurgh…"
Ren Xiaosu and the others were quietly watching from the defensive position as the expeditionary army's main forces approached.
P5092 looked through his military binoculars and suddenly got excited. "The barbarians' main forces seem to be approaching very hurriedly this time. Even their formations are not orderly. This is a once-in-a-lifetime opportunity for us."
Under normal circumstances, even if the barbarians were to attack the defensive position, they would do it in a very disciplined manner. But now, in a race against time, the barbarians in the tunnel had coordinated with the barbarians on the outside. They could no longer use the usual tactics and only wanted to attack the defensive position at full speed.
In this way, a lot of weaknesses would be exposed.
P5092 immediately gave orders. "Let's take it slowly this time. Let them get a little closer first. I want to take out these troops today!"
After that, P5092 looked at Ren Xiaosu. "Future Commander, this is an opportunity you created for our defensive position!"
"Ahem, not so loud, not so loud, please," Ren Xiaosu said.
While they were talking, the expeditionary army's main forces were about to arrive at the front of the defensive position. However, the commander of this group was a little puzzled. Didn't the elite warriors say they were going to coordinate for an attack from the inside? Why did it seem like nothing was stirring in the Central Plains' defensive position? Could their own experts have failed?
No way. He had not heard any explosions or gunshots earlier. He knew very well how strong those experts were, so there was no reason why they would get killed by the Central Plains people without a sound.
That was right. Those experts were probably waiting for them to attack first. After all, it was a little dangerous to breach the position from the tunnel. It would be better to attract the attention of the Central Plains people on the surface first so they could conceal their movements!
Yes, that must be it!
"Attack! Attack with all your might!" The regimental commander shouted, "Blow the attack horn!"
The commands of the barbarian troops were basically issued through signal flags and the sound of horns. So when the horn sounded a drawn-out signal, all of the soldiers in the main forces started dashing madly towards the defensive position without any regard for their lives.
But before they could get to the point below the defensive line, the ground in front of them suddenly cracked. Right after, it caved in.
When the charging barbarians smelled the scent emitting from underground, they vomited several times on the spot!
Then, when a few people who were covered from top to bottom in filth crawled out of the yellow torrent, they vomited even harder!
Anatoli wiped his face and shouted, "What are you standing there for? I'm Anatoli of the expeditionary army's advance guard. Hurry up and pull the others up!"
However, the other barbarian soldiers looked at him and hesitated for a few seconds without moving forward.
First of all, this sight was a little strange and no one could make out Anatoli's face. Second, it was way too disgusting and they could not bear to do it.
"What are you waiting for? Hurry up!" Anatoli roared.
But what answered him this time was the sound of gunfire coming from the defensive position.
Amid the loud sniping, Yang Xiaojin received Ren Xiaosu's directive to open fire on all the barbarians who emerged from the tunnel.
According to Ren Xiaosu, she did not have to worry about the others and only needed to snipe the elite barbarians.
As the battle unfolded, more than a dozen machine gun nests at the defensive position opened fire. In the past, they would only be able to take out about 2,000 barbarians' troops in a single day. But this time, it was definitely the best opportunity for the 6th Combat Brigade to attack the expeditionary army.
Amid the gunshots, an unconcealable light glinted in the eyes of the soldiers of the 6th Combat Brigade. Having been stuck at this defensive position for three days, everyone knew that even if they killed 10 barbarians for each one of their soldiers, they would still be wiped out. Right now, they really needed to score a great victory to boost their morale!
