From Chenjiagou, along the Meixi River, down the river for more than ten miles, is the White Emperor City. Although there are only about 300 people in Hu Yidao's hands, they are all the best elites among the elites, and if they suddenly come out from behind when the battle is raging, they may be able to pose a great threat to Zhang Kewang.

There are not many soldiers in the White Emperor City, this is known to everyone. Zhang Kewang's soldiers are not small, but White Emperor City is not a big place, and it can't accommodate so many people. There can be more than 2,000 people here. Zhang Kewang's soldiers were only the 2,000 cavalry, which were more elite. Moreover, these two thousand cavalry are not really troops that can fight on horseback, but are just infantry on horseback. As for the rest of the infantry, they were all brought in temporarily, and they didn't have much combat effectiveness. Zhang Kewang divided his elite into two parts, one of about 1,000 people, and placed them in the White Emperor City to act as the main force of defense; The other part is arranged in Kuizhou City, which can be regarded as protecting its own back road. As for the infantry who came with them, there were also more than 1,000 people who were deployed in the White Emperor City to serve as auxiliaries. Most of the remaining ones stayed in Kuizhou.

"A few strong men, how long will it take for you to go back to the mountain again?" Xuan Yi asked the five people.

"Overseer, we came over the mountain, and we had to open our own way all the way, and it took us five days to turn over. But it was much quicker to go back, because the road had been protruded, and ropes had been left in some difficult places. We'll be back in about a day and a half. The scout in the lead replied.

"Well, I have a military order here, you bring it back, and it must be handed over to Hu Yidao within three days." Xuanyi Daoist handed them a document sealed in a bamboo tube.

……

The revolutionary army and Zhang Kewang's army have been facing off in the Kuimen area for five days. During these five days, the revolutionary army would organize two rounds of attacks every day, and generally speaking, after the morning fog had cleared, the revolutionary army would launch their first attack at most half an hour, followed by another after lunch. However, the terrain around Kuimen determined that the scale of these attacks was quite limited, and the attitude of the revolutionary army was not very positive, so these attacks were easily repelled by Zhang Kewang. Of course, for the same reason, the casualties on both sides were actually very small. Judging from the number of casualties alone, to the melee of some later African warlords, the two sides mobilized tens of thousands of troops, fought for a month or two, and finally suffered dozens of casualties.

By the early morning of the sixth day, there was still a heavy fog on the river. Fog is an obstacle for both the attacker and the defender, and for the defenders, such fog greatly reduces their detection distance from the enemy, making their various long-range firepower almost useless. Often, when an enemy is spotted, the two sides will enter hand-to-hand combat. This is certainly not a good thing for the defensive side that occupies a favorable position. On the other hand, fog is also a huge obstacle for the attacking side. In the fog, the commander simply could not see the situation of his troops and therefore could not issue effective commands. This made the attacker's army de facto disorganized. In contrast, the defending side is familiar with the terrain because of its geographical position, and if it has a certain amount of preparation, it is easier to maintain a degree of organization.

Because of the uncontrollable factors that the fog would bring, the revolutionary army had never attacked the White Emperor City in the fog before.

But this morning the situation was a little different, although through the fog and the roar of the river crashing against the mountain walls on both sides of the gate and the mounds at the entrance, the sentries still faintly heard all kinds of sounds coming from behind the thick fog, the sound of footsteps, the sound of weapons cumping and clashing, and even the sound of horses. Obviously, an army is quietly approaching taking advantage of the fog.

The sentinels naturally immediately sounded the alarm, and Zhang Kewang immediately led the army into the position, preparing to resist the onslaught of the enemy army.

"He Zhangqi's playful attack a few days ago was mostly to make the soldiers more familiar with the terrain here. He must have been preparing for this attack since then. Zhang Kewang looked at the thick white mist in front of him and thought like this. He estimated that He Zhangqi's trick should be like this: first take advantage of the fog to approach a place very close to the White Emperor City, and then wait there, and when the fog gradually dissipates and both sides can see each other, they will immediately attack.

"It's just that the front pass is just so wide, and there are at most two or three people rushing up to the front row. Two or three people, how can they rush us? Zhang Kewang looked at the sky - although it was also foggy, but looking at the brightness, he could estimate the approximate time.

"In a little while the fog should lift. Well, Li Ergen, where is your tiger squat cannon? Shoot two shots over there! Zhang Kewang shouted.

A few steps away was the artillery position arranged by Zhang Kewang. After the occupation of Chongqing, Zhang Bingzhong also captured some artillery. However, Lao Zhang has never cared much about the cannon, in his opinion, this thing is just a sound, and it will also slow down the speed of the march, so those copper cannons have been remelted by Lao Zhang (copper is a valuable thing), and the tiger squat cannon made of pig iron was left behind and lost to Zhang Kewang.

"Howler!" Li Ergen answered over there, and then two cannon shots rang out from there.

After these two shots were finished, Zhang Kewang immediately pricked up his ears and listened to the movement on the opposite side, and there seemed to be no movement on the other side.

"Li Ergen, you useless goods, you are crooked, and you haven't hit a single hair. A few more shots! Zhang Kewang smiled and scolded at Li Ergen. Not hitting the target is actually in Zhang Kewang's expectation, this blind fight that can't see anything, can't hit, it's much more normal than hitting anything. After all, Zhang Kewang, and even the entire Zhang Bingzhong group, did not have much experience in defensive warfare, so naturally they would not have conducted artillery test firing before the war and compiled a complete firing table or something. Now that you can't see anything, relying on your memory to shoot indiscriminately, what you can hit really depends entirely on luck.

The reason why Zhang Kewang asked Li Ergen to fire a few more cannons was not really expecting how many people those tiger squat guns could kill under such circumstances, but to use continuous artillery bombardment to reduce the nervousness and fear of the soldiers in the fog when facing an enemy who might be close at hand but completely invisible.

At this point, the fog began to dissipate gradually, but it was still a while before it completely dispersed. Zhang Kewang naturally couldn't see it, but just two or three hundred steps to the northeast behind him, a group of soldiers of the revolutionary army was moving.

These soldiers were the more than 300 people that Hu Yidao carried. Last night, they quietly approached the White Emperor City from behind. At this time, the fog was slowly dissipating, and although it was still not clear to see anything else, the shadow of the White Emperor City was gradually emerging from the fog.

Hu Yidao did not plan to go to White Emperor City by land. The White Emperor City is surrounded by water on three sides, and only one side has a ridge that is not wide and connected to the White Emperor Mountain. This must be the focus of Zhang Kewang's defense, and he pounced directly on here, and his three hundred or so people were not enough to fight. Hu Yidao planned to take the waterway, cross the water, and land directly from the back of the White Emperor City.

It was impossible to launch a waterway attack from the direction of He Zhangqi, because they were in the lower reaches, and in the Qutang Gorge, the current was turbulent, and it was impossible to sail against the current. But Hu Yidao's side can go downstream. Moreover, his location is still outside Qutang Gorge, and the current is not so fast, although the boat is not without risk, but it is not impossible.

Last night, Hu Yidao made people set up some bamboo rafts overnight. At this time, under his command, everyone lightly put the bamboo raft into the water, and then they all put on their red hair, followed the water, and drifted towards the faintly exposed outline of the White Emperor City.

The fog was dissipating faster and faster, and although I couldn't see it clearly when I looked ahead, I could already see the outline of the mountains when I looked up. After a while, the sun began to shine on the cliff on the right, and then reflected again. With the reflected sunlight, I can already faintly see the road opposite.

At this moment, several flames burst out from the opposite side, and then a large number of shotguns swept over, knocking down four or five defenders at once. It turned out that the revolutionary army actually carried the large elm cannon over. After the cannon was fired, the soldiers of the revolutionary army who followed the cannon rushed forward with shouts.

At this time, Hu Yidao's bamboo raft had already reached a place that was only more than ten steps away from the cliff in the north of the White Emperor City. The attention of the defenders in the White Emperor City was attracted to the other side, and no one noticed that just behind them, dozens of bamboo rafts were approaching.

Hu Yidao pulled a flying claw (a kind of claw with a rope) twice, threw it forward and upward, this flying claw flew out, wrapped around a branch on the cliff wall, Hu Yidao pulled the rope to let the bamboo raft lean against the cliff wall, and then he bit the knife in his mouth, held the rope with both hands, pulled it, and then climbed up along the rope.

Hu Yidao climbed the cliff first, and then the other fighters also climbed up one by one. This direction is a cliff, so Zhang Kewang did not send troops to guard it at all. At this time, his attention was also drawn to the frontal hand-to-hand combat.

Relying on the fog, the distance was smoothly compressed, and the revolutionary army soon began hand-to-hand combat with Zhang Kewang's army, but because the capacity of the battlefield was limited, and Zhang Kewang was the most elite troops here, so for a while, the revolutionary army was not able to break away from the defenders, as the fog dissipated, and more defenders were invested, Zhang Kewang felt that he should soon be able to repel the enemy's attack again. But at this moment, from the direction behind him, a shout of killing suddenly sounded.
