Although the new annex only moved the heavy trebuchet forward a hundred meters, it took a day. Just as the engineer was adjusting the equipment, a shrill howl was heard overhead, and an urgent cannonball fell from the sky, smashing between the trebuchet and the bed crossbow position, and dusting the already white-sunned earth. Since the night battle against the Banshu military barracks, it has not rained in the Divine Arm Castle. The land at the east gate is a highly hydrophobic slope of mud and rock, and under the heat and sun, the land has become very dense and hard, which is why Liu Cheng tried to dig the tunnel but eventually gave up. The tunnel should be dug into the city of the divine arm, and the amount of work

It's huge, and it won't work at all without three or five months.

The sudden arrival of this shell frightened the new annexed troops, and they fled in all directions. A few of them fled quickly and rushed to the Overseer in a puff of smoke. The bright swords and axes in front of them made their necks cold, and they couldn't help but shrink their heads, and when they turned their heads and saw that there were no more shells, they returned to the trebuchet again.

At this time, a lieutenant was pulling his neck to cheer his subordinates: "Brothers, the Thunderbolt army in the city does not have heavy artillery, some are only small cannons, so I can't wait." All it takes is to break through the third wall to recapture the Divine Arm City. Lord Liu Cheng has already presented the commander of Niu Ling, and the official who has won the first merit of the city has been promoted to the fifth level, and the reward is thousands....... "This captain said spittle, and those big-headed soldiers listened to it with enthusiasm, and they couldn't wait to immediately put on their wings and fly into the city to fight for the wealth of the sky.

"There must be a brave man under the heavy reward", the soldiers of the new annex army in front of the city of the god arm shouted, and even the people who twisted the rope of the trebuchet shouted an impassioned trumpet. The engineer technician who operated the bed crossbow in the back was also whipping the oxen vigorously to make the crossbow strings more tense. Liu Quan, who was supervising the battle in the back, couldn't help but feel relieved. With the morale of this army, why worry that the Divine Arm City will not be lost and regained? Only by keeping this city can the Mongolian army be invincible, and its glory and wealth will be guaranteed. Just as he was about to give the order to attack, a series of cannons were heard behind the third wall of the Divine Arm City, and the cannonballs smashed into the trebuchet position with a screeching sound.

Liu Quanqing knew that something was wrong, and urgently ordered the bed crossbow to fire back. Dozens of spears struck the third wall with a roar, some even half of which had been submerged, and the remaining tail was trembling outside the wall, and the sound was quite terrifying. However, the actual damage caused by the ballistas was limited to this, and not a single Thunderbolt was injured. Because the Tiger Squat Cannon is a curved firepower, it can be deployed against the root of the wall, and the ballistic straight crossbow spears are blocked by the city wall. On the other hand, this round of artillery of the Thunderbolt army covered the trebuchet position, although the losses of the new annex army could not be seen under the rising dust, but judging from the number of new annex soldiers who fled back in embarrassment, it was also a great success.

Before the smoke of the first round of artillery had cleared, another shell fell into the bed crossbow array with a scream, which coincidentally broke the bowstring of a bed crossbow, and frightened several engineering technicians operating the bed crossbow to cry and flee desperately. The cry was like an order to withdraw, and for a moment the new annex soldiers on the bed crossbow position ran back with their feet drawn and fled back with the remnants of the trebuchet position.

Although these soldiers of the new annex army did not know what it meant to test and calibrate fire, they all knew that after this shell, a dense number of shells would inevitably fall. The shadow of death overcame the fear of the Warlords' axemen. Under the onslaught of the surging rout, Liu Cheng had no choice but to retreat to the rear camp with his own troops. He now finally knew what the Thunderbolts had sent into the city two days ago.

Surrounded by Liu Quan's own soldiers, he hurriedly retreated to the rear camp, and at this time, the shells of the Thunderbolt army arrived as scheduled. The bed crossbow was definitely a high-tech weapon in the era of cold weapons, much more technological than trebuchets, and its production was very delicate but also very fragile. Although Liu Cheng ordered people to build a low wall and set up a shield to protect him, he could not prevent the cannonballs falling from the volley. After a few rounds of bombardment, the bed crossbow was blown to pieces, and although the main structure was not damaged, it was obviously unusable. In contrast, although the trebuchet position suffered several rounds of shelling, most of the trebuchets were still standing after the smoke cleared, but a circle of new annex soldiers fell around them, and a few hundred people were seen.

Before the tiger squat cannon fired, Liu Cheng was full of confidence in recapturing the Divine Arm City. After the shelling, the flame of hope in his heart had been extinguished. It's just that Niu Xuan is willing to give up the Divine Arm City easily, and his ambiguous attitude in the dispute between the two khans has been suspected by Kublai Khan, and now he finally has the opportunity to make meritorious contributions. Although Kublai Khan gave him the task of being sure to ask for Liu Quan, he did not specify other tasks. However, in Niu Ling's view, the Great Khan's edict did not state that Luzhou would be taken, but in his words, Tongchuan Mansion Road had already been regarded as a bag. If he only returns with the remnants of more than 1,000 people of Liu Quan, it will be a failure or even a failure, which means that his prestige will be damaged, and it also means that he and his family will lose power and be marginalized. He decided to continue attacking the Divine Arm City, after all, his own side was superior in numbers, and the battlefield was on land. No matter how strong the Thunderbolt army was, they did not dare to go ashore to face the charge of their own cavalry.

After these few days of fighting, Liu Quan's men have been reduced to more than 1,000 people. Relying on this, if the personnel can't take the Divine Arm City, it is tantamount to a fool's dream. What's more, although his subordinates are elite, they are blown out of the psychological shadow by firearms. Today's tiger squatting and artillery bombardment have turned these veterans of a hundred battles into frightened birds.

Niu Xuan knew that Liu Quan's army was no longer of great use, and might even blow up the camp in the wind, so he transferred another 1,000 new attached troops to Liu Quan's command. Liu Cheng knew that the combat strength of these new annexed troops was worrying, but seeing that Niu Xuan had made up his mind to continue the attack, he had to select 400 people from them, and draw 100 elites from the remnants, preparing to carry out a night attack on Shenjian City. Before leaving, he gritted his teeth and sent his own personal army to accompany him. There was only one chance for a night raid to succeed, and in his opinion, victory or defeat was a matter of victory.

Taking advantage of the third watch when the moon was bright and the stars were scarce, Liu Quan's personal soldier captain led people to quietly touch the east gate of Shenjian City. The family of the captain of this pro-soldier is still in the city, and Liu Cheng promised to promote him to the prefect of Luzhou after taking the Shenjian City, and the rest of the soldiers will also be rewarded for their meritorious deeds, so these 600 people are full of fighting spirit, and they will become benevolent if they do not succeed.

The first and second walls were saturated by trebuchets and covered with holes and stones, which made it quite inconvenient to walk, but eventually collapsed in many sections, and it was not difficult to follow the gap to the third wall. As long as they cross this last wall and open the gates, the army of Niulin can rush in and retake the Divine Arm City. In order to advance lightly by surprise, the soldiers of the new annex army carried only hooks and ropes and short ladders.

The soldiers of the new annex army silently rushed towards the city wall, and when they were still more than ten meters away from the city wall, the soldiers who rushed to the front let out a miserable scream, rolling on the ground with their feet in their hands, and the open space in front of the original city wall was sprinkled with triangular nails, which were originally used to prevent horses from charging, and the killing effect on the infantry was naturally not a problem. To say that these new annexes are also brave, seeing that their teammates in front stepped on the iron nails, the ones behind still rushed forward, but unexpectedly detonated the mines under the city wall.

Seeing that the sneak attack failed, the captain of the army hurriedly ordered all the troops to attack, but as soon as they reached the base of the wall, large and small round objects were thrown on the wall—the small ones were mines, and the large ones were clay pots filled with fire oil. A series of grenades exploded, followed by a burst of explosive oil. Under the skyrocketing fire, a large group of new annex soldiers turned into humanoid giant candles, screaming and rolling on the ground. The soldiers of the new annex in the back were so frightened that they threw down the ropes and short ladders, and fled to the camp below without looking back.
