Lin Shanhe shouted with a sinister grin, "Open fire."
The 6,300 rapid-fire cannons roared to life, especially the 300 enhanced rapid-fire cannons deployed on the front lines, which were ferociously destructive.
Each alloy shell could penetrate several skeleton knights before exploding violently.
In an instant, several rows of charging skeleton knights were mowed down.
Listening to the sounds of numerous hooves, Lin Shanhe and the others could confirm that all 3 million skeleton knights had been deployed.
This meant that half of the battlefield, including the jungle ahead, was filled with charging skeleton knights.
Lin Shanhe quickly sent a message to Lin Hu: "Huzi, at 1500 meters in front of the position, maintain a distance of 200 meters, advance with a barrage, and fire."
Lin Hu, who had been waiting for the message, quickly relayed Lin Shanhe's orders to Lin Ying. Moments later, the 8 heavy artillery platforms and 4,000 heavy cannons roared to life once more.
Due to the relatively high mobility of the skeleton knights, Lin Hu and Lin Ying employed saturation bombardment. They were not afraid of wasting shells but rather aimed to maximize the density of shells to increase enemy casualties and slow down the skeleton knights' charge.
While the central army's front line was engaged in fierce fighting, Leng Shan and the sacred beast White Tiger also discovered the trolls sneaking up from the jungles on both sides.
The Boa Constrictor clan and the White Tiger clan were naturally hunters of the forest, and the dark night had no effect on their members.
The silent assassination of the trolls began.
One million White Tiger tribesmen, one million Boa Constrictor tribesmen, and 2.5 million from the Leng Shan Hunter Legion all gathered in the forest to the left of the central army.
Although there was no ambush in the right forest, the mad little Daoist had the Hunter Legion mine the entire forest with explosives.
For this purpose, the little Daoist produced 5 million bombs of various sizes, leaving no gaps in the right forest.
The First Army Group and the Fourth Army Group each had one legion stationed on the right flank.
The logistics corps, aware of the bomb-laden right forest, specifically strengthened the defenses on the right flank.
All the soldiers stationed on the right flank hid in the defensive bunkers, fearing that the explosions might harm their own men.
The trolls attacking the left flank quietly crept towards the human positions under the cover of night.
However, in the rear of the formation, unseen by anyone, trolls were having their throats slit or were being tied up like zongzi by Boa Constrictors descending from the trees.
By the time the trolls reached the human positions on the left flank, more than a tenth of their warriors had been silently eliminated by Leng Shan and his men.
"Enemy attack, defend, launch illumination flares."
The left flank became lively the moment the trolls approached.
Illumination flares were launched from the positions, and nearly a thousand large searchlights instantly focused on the jungle on the left.
The trolls, who were preparing to surrender, were instantly illuminated clearly.
"Bowmen prepare, fire." Following the orders of the two legion commanders, arrows and javelins whistled towards the enraged trolls.
The trolls at the forefront of the charge fell like wheat stalks, row by row.
Seeing the left flank engage, Leng Shan quickly signaled the Hunter Legion to draw their bows and arrows. Armor-piercing arrows, coated with potent poison and glowing with a blue light, were shot towards the rear of the troll ranks.
The charging trolls never expected the fatal blow to come from behind.
"Ah... Enemy attack, there are enemies behind us."
Screams erupted.
Amani quickly looked back and saw people swarming in the forest behind him. He immediately shouted, "Amani tribe, turn around and block the enemies behind us. The rest of the tribes continue their attack on the human positions."
"Send a signal, tell our tribesmen in the right forest to speed up their attack on the human positions..."
"Boom. Boom. Boom."
Before Amani could finish, intense explosions began to erupt from the right forest.
The two legion commanders on the right flank, looking at the elemental energy of thunder and fire brought about by the fierce explosions in the forest, couldn't help but swallow.
"My word, this son-in-law is too damn ruthless. With this kind of explosive power, how many troll lives would it take to fill the void?" said the legion commander from the Fourth Army Group, his face full of apprehension.
"Exactly, exactly. That's why they say don't provoke these cultivators. They're too brutal," the legion commander from the First Army Group agreed wholeheartedly.
Leng Shan chuckled as he watched the charging trolls and then let out a whistle.
300,000 Leng family tribesmen released their hunting dogs and war hounds.
"Damn it, I didn't dare to let my dogs bite you in the forest for fear of heavy casualties. Now that we're in open terrain, if I don't let them bite you, it would be coddling you too much."
Whistles sounded continuously, and 3 million Leng family war hounds, in coordination with the White Tiger tribesmen and Boa Constrictor tribesmen, fiercely clashed with the troll army.
Leng Shan's Hunter Legion also picked up their melee weapons and engaged the trolls.
Seeing that reinforcements had arrived, the two legion commanders on the left flank grabbed their large sabers and shouted, "Brothers, these troll bastards have fallen into Commander Yue's ambush. Brothers, follow me and chop these sons of bitches!"
Without a word, the soldiers of the two main combat legions left 100,000 men to defend the positions, preventing a troll ambush, while the rest grabbed their sabers and spears and charged towards the trolls with roars.
Xuan Zhen, leading 1,000 kings from the Great Shang Ancestral Court Guard, had been hidden in the deep forest.
Seeing that close combat had already begun with the trolls, these kings from the Great Shang Ancestral Court Guard immediately located the troll kings and, in pairs, began to slaughter them.
Dian Wei, who had been guarding Leng Shan's side, found Amani immediately after the battle began.
The once incredibly powerful Amani encountered the human general Dian Wei. After only a few rounds, his head was severed by Dian Wei's halberd.
With the addition of the Great Shang kings, the troll kings fell one by one.
The armies of the Human Alliance, led by a group of kings, were filled with high morale and fearlessness. For a time, they actually gained the upper hand against the numerous trolls.
Leng Shan, observing the battlefield, blew his whistle again.
Leng family tribesmen began to disengage from the battle and retreated into the deep forest once more.
"Brothers, don't push these bastards too hard. Leave a path for them to escape, and we'll deal with them slowly."
Everyone understood Leng Shan's intention and cleared the path leading towards the forest.
