Yin Hongfei, who had been monitoring from the air for a long time, saw this scene and felt a little relieved in his heart. At present, the soldiers are no longer in danger of being overturned as they were just now! But the situation still cannot be solved. No, there is a huge number of demons and beasts coming from behind. Such a thrilling scene, even he, a veteran god of war, was very worried in his heart.

In order to prevent the situation from getting out of control, the order was decisively issued. Let the follow-up troops build a defensive earthen wall along the battlefield, and welcome the retreat of the troops in front to defend together. Otherwise, if you continue to fight endlessly like this, even if you are a King Kong indestructible body, you will not be able to withstand long-term wear and tear. Besides, if the wounded soldiers did not receive treatment earlier, they would have been dragged down and sunk. After this, all the troops who came to hunt in the Valley of the Dead can be said to have thrown themselves into it.

As soon as the order was delivered, Cao Su and many other battalion commanders below commanded the battalions to slowly retreat towards the earthen wall behind. At this time, the earthen wall in the rear had already been built into an earthen wall ten meters high, twenty meters wide, and several thousand meters long.

With the current height of the earthen city wall, it is tantamount to a mantis arm blocking the car for those demons and beasts with high and profound paths, and many soldiers can be added to guard it, and it can also be used to fight with it for a while.

Qin Jian's Huwei battalion had already retreated with the army all the way back, and now the armies formed a one-word line. The demon giants in front of them kept pouring towards this side. But under the triple defense and all-out attack of human beings, its own losses are also extremely huge. But this only stimulated the greed of the demon beasts even more, seeing the corpses of their companions competing to eat and eat them, and then continued to rush to kill without fear of death with red eyes.

All the battalions were under such pressure that they could barely breathe. had no choice but to retreat again, relying on the earthen city wall for defense. Seeing that the number of demon monsters has increased again, Yin Chongfei, who is monitoring the battle situation from the air, has long been unable to search for the old demon lurking in the demon beasts. Yun Zuyuan Li raised the 'thunder palm' and slammed down, and suddenly only heard two thunderbolts. The source power that raged suddenly exploded in the demon giant beast group. Hundreds of demon beasts with a slightly lower path were swept away like autumn winds sweeping away leaves. This kind of shocking palm power shocked Qin Jian so much that he opened his mouth wide, and he almost couldn't close it! I didn't think that in the hands of the peak powerhouse of the Tongtian Stage, this ordinary extremely powerful palm technique would have such great power!

It was extremely rare for all the soldiers on the ground to see the boss take action in person, and they shouted excitedly. The demon beast suddenly suffered a major blow, and it was a little hesitant for a while. Seeing this favorable opportunity, the armies threw off their opponents and calmly retreated.

Qin Jian and the others quickly jumped over the earthen wall, and the waiter stood guard above. A large number of soldiers took out their bows and crossbows from their storage bags. This crossbow is coated with runes that break the source power shield. The lethal effect is particularly noticeable when used in large quantities. Behind the demon monster is swarming to chase to, before the trance, the arrow rain is like a waterfall rushing down, a large number of demon beasts were injured for a while, and then the demons who are still chasing are due to the large number, so that the impact inertia and can not turn back in time, under the trampling of each other, the corpses of the demon monsters are suddenly piled up.

"Attack!"

Such opportunities are extremely hard to find. Humans have long been fighting demon monsters, and they have long been aware of their weaknesses. In the battle, they often only care about individual rushes, and the species only use each other without any rules at all, as long as there is a trace of profit, its ferocious greed is immediately presented, at this time, since there are so many demon monster corpses on the ground, how can the demon monster that smells of blood behind it be willing to let go of such a god-given opportunity, and randomly launch a crazy devouring. As a result, humanity seized the opportunity to launch a major counteroffensive.

In this wave of attack, all the troops did their best, and even the soldiers who participated in the defense in the rear attacked on all fronts. For a time, a huge numerical advantage was formed locally. The demon beast was blocked by the front attack, and the loss was even greater!

But even with such a large number of kills, there were still a flood of demonic beasts like cow hair. It's completely incomprehensible why this demonic beast suddenly has so many numbers overnight?

You must know that since the siege of the National Death Valley, the demon giant beasts that have been eliminated by humans have reached more than hundreds of thousands, but I didn't think that this not only did not reduce their number, but killed more and more, and their Taoism became more and more profound, directly oppressing the human race This wave of attack momentum only lasted less than a quarter of an hour, and the offensive has turned into a stalemate, so that the casualties of human soldiers have increased, and the demon beasts have seen this fierce flame more and more blazing!

Seeing that this continued, a large number of soldiers had to die in the devil's mouth, and the generals saw that the situation was not right, and they ordered to shrink their ranks and desperately defend the earthen city wall.

Such an offensive and defensive back-and-forth, if it is counted as one round, at this moment, the human race has been engaged in a tug-of-war with the demon beasts for as many as ten rounds. Not to mention the rest of the soldiers, even Qin Jian was a little out of breath with a super small universe. Fortunately, after so many battles, the demon beasts are also seriously injured. The offensive was no longer as ferocious as it had been, so that the soldiers who had to guard the city walls could be replaced in batches to rest.

Qin Jian and his ten personal soldiers had just been replaced at this time, so they stayed by a small mound not far behind the earthen city wall to rest, and hurriedly ate and drank some dry food and water.

"Team Qin! It seems that this battle must be fought for a few days, should we first go to the military pharmacist to exchange some pills and come back? In case we don't get rest for a long time, we can make up for the temporary shortage of source strength. Leon suggested to Qin Jian.

When the brothers next to him heard this, they immediately joined randomly. In particular, one of the personal soldiers named Miyagu was the weakest among all because of his cultivation, and when he heard this, he screamed loudly: "Oh! Yes, yes, yes! I have been fighting for so long just now, and my source power has long been weak, if it weren't for the Qin team to escort me, I would have hung up my mother's aid." Let's go and change some now, or I'll have to say whether my brother will die next time. When everyone saw his anxious and painful appearance, they all burst out laughing.

"Does this military still have any pills to exchange?" Qin Jian also heard it for the first time, and couldn't help but be surprised.

"Of course there is! Team Qin, you have just come to the army, and you don't really know the whole army. In fact, every time there is a big action in our army, its pharmacists must follow the army. This is also a guarantee of the army's combat strength! Otherwise, what's the use of us getting so many demon beast corpses? Besides, just relying on the empire's little bit of source crystal, I can't improve my cultivation in this life. Fortunately, there are treasures such as elixirs in this world, which can not only improve cultivation but also treat injuries, it is simply a perfect artifact!

"Oh——" When Qin Jian heard this, he suddenly remembered that he had obtained many divine skills and immortal techniques in the inner room of the Lei Hall, and could there be a secret method for this medicine alchemy. So he hurriedly called up the inner chamber of the brain. He hadn't had time to check and sort out these magic skills since the end of time.

One by one, he actually saw more than a dozen secret recipes for refining pills. These secret methods of refining pills are not too difficult to practice. It is nothing more than using the source power to purify the corpses and inner pills of various demon beasts, and then adding various immortal grasses so that people can easily absorb their essence. It plays the role of enhancing the source force and cultivation. It seems a bit complicated, but as long as you master its secret method, plus there are a large number of raw materials, Qin Jian's cultivation at this time can be easily mastered in two or three days. It's a pity that Qin Jian doesn't have any more materials now, and the other doesn't have time to cultivate and control such secret methods. So he sat up and said to Leon, "Brothers, in that case, let's quickly send someone to exchange some pills and come back." ”

"Hmm, Team Qin, why don't we go together! There must be a lot of people who exchange there, and each brother's physique cultivation is different, and the pills they use will also be different. Leon reminded.

"Okay! Let's hurry up, or it will be our team's turn to defend later. Qin Jian said and quickly got up, seeing that all the brothers lying on the ground had already stood up, and looked a little impatient, he smiled and motioned for them to lead the way.

In fact, Qin Jian's subordinates had long wanted to use the large number of demon and giant beast corpses they had stored to exchange for pills. During this time, they were no longer in danger of dying under the protection of Qin Jianjian, and everyone could be said to have made a lot of money. Besides, the pill can quickly replenish the deficit source power, which can greatly improve one's combat effectiveness. In addition, when cultivating, you can also use this to offset the amount of source crystals. This is also the biggest reliance of all martial arts monks, otherwise it would not be enough to rely on the army to distribute that bit of source crystal, even to plug the gap between the teeth.

In fact, these soldiers have one of the biggest responsibilities in the army, that is, to repay their parents and families. What does it depend on? It is this source crystal, often as long as they bring one source crystal home, their parents, wives and children can live happily for a year! So that in the use of Yuanchang, unless they encounter a bottleneck, under normal circumstances, they can only desperately kill more demons and giant beasts on the battlefield and come back, and exchange them for pills for improvement。。。。。。

Qin Jian followed everyone, and under the leadership of Leon, he walked back less than five hundred meters along the small mound, and he had already found several large camps. At this time, a relatively flat square in front of the big camp tent was already overcrowded. Everyone scrambled to squeeze in. Trading with a row of soldiers in special costumes in front of the tent.

Finally, Qin Jian and the others finally squeezed in, and saw a long table in front of them, which was full of bottles made of various crystals. Inside there are all kinds of pills of different colors. In addition, soldiers are probing the corpses of demonic behemoths in the storage bags of the soldiers who have come to exchange them. After a while, a soldier happily took the elixir poured out of a crystal bottle. I saw that he quickly took out a jade bottle from his storage bag and carefully filled the pill. He went away full of joy.

The fragrance that emanated when the soldier took out the pill just now was not only fascinating, but even his own source power had also increased a little. It can be seen that its effect is indeed extraordinary. Seeing this, Qin Jian also hurriedly untied the storage bag from himself, which was still the trophy he picked up when the army returned to defense. He had fed the blood-eating aardvarks before. However, the number of them is pitifully small. The soldier poked into it, frowned, and said contemptuously: "I said little brother!

"Uh! This big brother, I have dozens of demon corpses that have been practicing for a hundred years here! Can't I even exchange one? Isn't your elixir a little more expensive?"

Seeing Qin Jian's immature face, this knew that he was a soldier who had just entered the army, so he patiently persuaded him: "Little brother! Yes, you have dozens of demon beast corpses, but they can be truly exchanged, and they can only be exchanged for the lowest-grade 'Shengyuan Pill'. However, the number of them can only be ten. So I advise you to wait until next time to collect more together, and it would be more cost-effective to exchange them. ”

"Oh——" Qin Jian was relieved when he heard this. I thought that according to the secret method I got from the inner room of Lei Tang, I specially introduced the entire process of its medicine. He divided all the pill making methods in the mainland into low-level, intermediate, high-level, and top-level levels from easy to difficult. And making this kind of Shengyuan Pill can be described as very simple, as long as it is purified in a hundred-year-old demon giant beast corpse, even the immortal grass inner pill can be made into more than a dozen without adding it, if your own dozens of demon giant beast corpses are not counted as inner pills, you can make at least a few hundred if you specialize in making this kind of Shengyuan Dan without any problem. This soldier said that he could only exchange for a dozen or so pills, this kind of interest rate difference is really a million profits! Qin Jian hesitated unconsciously after thinking about it, and finally thought that he didn't have to rely on taking pills to improve his source power now, these demon giant beast corpses were trophies anyway, and it was a good thing to change a few to study and study first.

Thinking about it, he nodded at the soldier and said, "Come on, this big brother, you can change that kind of Shengyuan Pill for me! Anyway, my cultivation is still low now, so it doesn't matter." ”

"Team Qin, don't worry!" Leon and the others had already heard the conversation here, and saw that Qin Jian only had a pitiful dozens of demon giant beast corpses for himself and the others, and at this time, they actually exchanged them for this lowest-grade Shengyuan Pill, which made them feel how to get by, and even put down the matter of exchanging the pill for themselves and the others, and hurriedly took his storage bag and handed it to Qin Jian.

Seeing this, Qin Jian was also moved in his heart. He waved his hand and said, "Thank you, big brothers." The younger brother has not yet reached the Fengjing stage of cultivation, so he doesn't particularly need the pill, but you have to improve yourself quickly. Now hurry up and change the elixir, time waits for no one, and you will have to go to the battlefield again in a while. ”

After Qin Jian's persuasion, Leon and the others were also ashamed in their hearts. It was only under his escort that he and the others got so many demon corpses, and now they not only refused to accept the gifts from their brothers, but let them persuade them. How fortunate are they to be able to follow such a magnanimous captain! Fortunately, they are all soldiers, thinking about Qin Jian now, as he himself said, he really doesn't use the pill much in the peak realm of the Voyeur Martial Arts. Just keep this feeling in mind. So everyone no longer insisted, and each went to exchange it for the pill they needed. Of course, among all the soldiers who came to exchange for pills, their amount could be said to be outstanding. Hehe!

When the soldier who exchanged pills saw this scene, he couldn't help but look at Qin Jian differently. I didn't expect that people would only peep into the martial arts cultivation, but instead become the captain of the Tiger Ben Army! I couldn't help but stretch out my thumb and raise it to Qin Jian. Now even the tone of his voice was much softer, and he transferred all the demon beast corpses in Qin Jian's storage bag with a smile, poured ten brown and black pills from a crystal bottle and handed them to Qin Jian, while asking Qin Jian: "Little brother, you are the lowest cultivation captain I have ever seen in the Tiger Ben Army, I really don't know how you sat in this position, it is too curious." Later, when the battlefield is free, can you tell your brother your own story? Of course, I won't let you tell it in vain, how about I give you ten of this Shengyuan Pill?"
