Junior Uncle is too cunning.

"Fellow Daoist Yu, you've really struck gold! Look at Chen Fusheng's sword strike just now; it already had a hint of the Great Dao of Swords. No wonder he deserves the title 'Ghost Sword'."

"Not only that, but this little guy has also mastered the art of troop deployment and military strategy. He has a bright future ahead of him."

……

As Yu Jinzi listened to the Taoists around her praising Chen Fusheng, she shook her head modestly, but her eyes were full of joy, and she was overjoyed.

At this moment, Chen Fusheng was completely unaware of the high praise he received from the powerful Golden Immortals, and was focused intently on the battlefield before him.

As the temporary leader of this legion, he was effectively the legion commander in reality, even though he was only nominally in charge, as Yu Jinzi was not involved in the affairs of the legion.

"Defend"

At Chen Fusheng's command, the body-cultivating cultivators standing in the front row stepped out of their ranks and charged towards the dozen or so demons that had already broken through.

Not only those who practiced body cultivation and immortality, but also a longsword squad led by Chen Fusheng also left the camp.

It's called a long sword, but it's actually just a club... a long spear and other long weapons.

Sticking close behind the body cultivator, after only a hundred and twenty steps, a tiger demon led three or four wolf demons pounced on them.

Chen Fusheng stared intently at the demon race's movements, a glint of light flashing in his eyes. He said in a deep voice, "Defend."

The body cultivator raised the defensive shield in front of him, connecting the shields one by one to form an invisible wall, and slammed it down on the demon race in front of him. With a "boom", the two sides collided.

Since receiving the order to advance towards the demon race, Chen Fusheng discovered a drawback: once they left the human race's heavily fortified battle lines, the human race's defenses plummeted and its mortality rate steadily increased as they advanced.

Of course, these were unavoidable casualties, and the human race's high command could only try to avoid them tactically. However, for a top-notch weapon refiner, Chen Fusheng immediately thought of whether he could solve this problem by focusing on weapon refining.

After that, he racked his brains. Although he could refine defensive magical treasures, he was only one person and could not produce enough defensive magical treasures for the entire battle line.

Furthermore, defensive magical artifacts are ultimately just simple protective tools; it's impossible for them to achieve the same effect as a defensive array on the human front.

Then he thought of whether he could inscribe some formations on each defensive magical treasure, so that each magical treasure could be regarded as a single array base, and then connect them to form a mobile protective array.

Chen Fusheng did what he wanted to do. Since Yu Jinzi wasn't around, he directly abused his power for personal gain and began his grand plan to train troops.

To be on the safe side, he initially crafted low-grade acquired spiritual treasures for his shields. In case the experiment failed, having low-grade defensive spiritual treasures would at least greatly improve his safety.

After a series of experiments, Chen Fusheng finally succeeded in forging a set of shield formations. Although these shields were made by Chen Fusheng, their design concept was still inspired by Cao Cao's chained warships in the Battle of Red Cliffs.

Although each of the shields designed by Chen Fusheng was a low-grade spiritual treasure, he incorporated a formation into each shield. Once activated simultaneously, they would form a protective array in the entire sky, with defensive power no less than the defensive arrays on the human race's front lines. Chen Fusheng gave this array a particularly catchy name: "Turtle Shell."

It is precisely because of the "Turtle Shell" formation that even if the demon race has passed the first attack and Chen Fusheng's sword, if they want to kill the human race, they still have to break the Turtle Shell formation first before they can reach the body cultivators and immortal cultivators, just like before.

The human race's high command quickly learned of this matter and, led by Yu Jinzi, came to investigate. Chen Fusheng did not hide anything and told them everything. To avoid unnecessary trouble, he selflessly put Cao Cao out of his mind and claimed the design concept as his own.

The higher-ups immediately recognized the brilliance of this idea and hurriedly returned to the Marshal's Mansion to invite all the weapon-refining masters and formation masters to study its feasibility.

Just three days later, with the great efforts of the masters, based on Chen Fusheng's "tortoise shell", some modifications and improvements were made, abandoning the use of acquired spiritual treasures as the array base and instead using ordinary spiritual artifacts.

After all, even if the Dao Alliance is large and powerful, it cannot support the distribution of millions of acquired spiritual treasures. Moreover, according to their experiments, even if ordinary spiritual artifacts are used as the array base, the defensive power of the "turtle shell" is only slightly weaker than the turtle shell array set up by acquired spiritual treasures.

Of course, this was also thanks to the help of the array masters. Chen Fusheng was indeed a master craftsman, and could even be said to be one of the top craftsmen below the grandmaster level.

However, everyone has their own expertise, and the formation he inscribed on the shield was only the most basic and common formation.

Among the array masters invited this time, several are disciples of the Jie Sect and are well-known figures in the Eastern Continent.

After seeing Chen Fusheng's formation, he just smiled and said nothing. This was not to mock him, but rather because he was even more interested in Chen Fusheng.

After all, Chen Fusheng is a master craftsman, and he deserves the respect he deserves. Moreover, someone who can come up with the "Turtle Shell" formation has a bright future. Besides, they can't hold a master craftsman to the same standards as a master formation master.

Afterwards, the array masters easily produced several sets of advanced defensive arrays and inscribed them on the array. This directly increased the power of the array several times over, so that even if the array base was changed from a defensive spiritual treasure to a common spiritual artifact, the power of the array did not decrease much.

It is said that even the busy Demon Slayer Marshal was alarmed and personally inquired about the matter. Subsequently, under the promotion of the Marshal's Mansion, the Dao Alliance exerted its full strength and, in just one year, ensured that every immortal in the front-line troops had one. The effect was quite remarkable, reducing the casualty rate by at least half. This saved not just one or two people, but the entire border between humans and demons.

However, to Chen Fusheng's dismay, since he submitted this idea and the tortoise shell formation, apart from Yu Jinzi bringing him back an improved version of the tortoise shell formation, nothing else has come of it.

Logically speaking, even if Chen Fusheng's actions don't qualify as having immeasurable merit, they are still of great benefit to the human race. He doesn't expect to be promoted or made rich, but at the very least, he should be rewarded with fifty or sixty pieces of refining materials and pills... or even a hundred thousand or so battle merits!

Several times he wanted to ask Yu Jinzi, but he was too shy to ask.

Fortunately, Chen Fusheng didn't open his mouth, otherwise even if the Marshal's Mansion and the Dao Alliance's higher-ups didn't react, Yu Jinzi could have strangled him herself.

A million or so! You have to know that killing a demon lord only earns a million battle merits. Even she didn't have that opportunity. How dare Chen Fusheng, a mere True Immortal, have such a thought!

Of course, Chen Fusheng no longer has this thought; it's just that in the quiet of the night, he feels inexplicably heartbroken.

The moment the demons made contact with the shields, the body cultivators immediately channeled their magical power into the shields, causing their blood and energy to surge. Their arms, waists, and entire bodies grew larger. With a loud shout, they pushed the demons stuck to the shields with all their might.

Seeing that the time was ripe, Chen Fusheng immediately shouted, "Charge!" and led the sword-wielding team out of the tortoise shell formation, unleashing a flurry of blows and slashes at the demons in front of them.

In particular, Chen Fusheng wielded the Azure Dragon Crescent Blade (a replica), a mid-grade acquired spiritual treasure, with great skill. Every strike was aimed at the vital organs of the demon race, such as the throat and eyes, making each blow potentially fatal.

A group of people took on one person at a time, and soon they had the group of demons in front of them knocked to the ground. Chen Fusheng knew when to stop and led his men back into the tortoise shell formation, waiting for the next wave of escapees.
