Although the feint attack accidentally used too much force to defeat the pass of the Cave Waist Mountain, Guan Yu quickly found that this mistake was still worth the money.

First of all, early the next morning, Huang Quan, who was in charge of torturing the prisoners, came to report that it was from the mouth of a captured Qu Junhou and the three tun chiefs that after half a month of tackling key problems, the number of enemy troops in front of Wei County had reached 30,000!

Not only did it attract a standing army of less than 10,000 people in the entire Jianning County and a temporary mobilization of more than 10,000 people, but also the Mengwei tribe in the border area of Jianning County and Yongchang County sent tens of thousands of reinforcements.

In addition, the captives also confessed, saying that when the commander Cai Fei was boosting their morale, he said that Gao Yi, the barbarian king of Yuewang, might also send troops to help, but Yuewang had a long way to go, so the troops had not yet arrived. After Gao Yi's reinforcements also arrived and Guan Yu's veteran soldiers were tired, Jing Yi would lead the South-Central Alliance Army to take the initiative to enter the open area to fight Guan Yu!

And the reason why the concave waist mountain pass is still lost in this situation is only because the terrain of the checkpoint is narrow, and too many troops cannot be deployed, and the side with many people cannot play.

After confirming the enemy's situation, Guan Yu became more and more sure of the effect of his enticing of the enemy - sure enough, the main forces came.

After another two days, Guan Yu determined that the danger of infiltration of his grain route was greatly reduced, so he sent a messenger back to Zhu Ti to urge Zhang Fei and Li Su-

This can be regarded as a side benefit of taking the concave waist pass, because when the wall is in the hands of either side, the defenders can force the enemy away from the open area within 200 steps in front of the pass, so that at night, the city head can use hanging baskets to drop people down, sneak out of the pass, and hide in the mountain and forest paths on both sides.

This is also the reason why Jing Yi and Cai Fei can repeatedly send a mountain-climbing team that is familiar with the terrain to intercept and kill Guan Yu's wheelbarrow grain transportation team.

Now that the wall has fallen into the hands of Guan Yu, Jing Yi and Cai Fei have sent people to infiltrate again, and the difficulty has suddenly increased by an order of magnitude.

Guan Yu waited anxiously in the pass for another ten days, and finally waited for the messenger to return by crossing the mountains and mountains.

"Where are the third brother and the military advisor?" Seeing the messenger returning, Guan Yu couldn't wait to ask.

"Returning to the generals, when I returned to Zhuti, the three generals were already about to set off from the waterway and enter Tushui from Lushui. Li Dudu told the general that he was also because the scouts had detected that Gao Yi, the barbarian king of Yuewang, was in a tendency to reinforce Jing Yi, and he was afraid that he would be bumped into by this unexpected enemy army halfway, so he immediately postponed the attack and let the enemy cross the river first. The rest of the plans remain unchanged. ”

Guan Yu brushed his hair and pondered: It turned out that Li Su's side was also because of the unplanned appearance of reinforcements from the Yue Net, and he was afraid that he would be attacked and dumpled by the front and rear attacks too early, so he let all the enemies over......

This is also the most common accident in ambush warfare, there are more enemies than expected, and it is always necessary to finish before you can start your pockets.

"Even so, it is not a big change, our army is guarding the concave waist pass, and moderately assumes the posture of continuing to harass the camp in the enemy's mountain road. The catapult in front of the gate was also dismantled and reloaded on the other side of the gate, pretending to be steady and steady to avoid suspicion from the enemy. ”

"Yes, General!" The adjutant general and the army were immediately ordered to do it.

……

Not to mention that Guan Yu's plan was unexpectedly completed perfectly, like an anvil to attract all the main forces of the enemy.

On the other side, Li Su and Zhang Fei, who had originally planned to send troops in late August, held their starting positions in Zhuti County for an additional 15 or 6 days, and stayed up until the end of early September before they officially started by water.

As a result, the "August Dulu" has become a more stable "September Dulu". The fleet struggled for two days on the turbulent Lushui (Jinsha River) before turning to Tushui (Niulan River), where the current was much slower and the water level was much shallower.

After entering the water, the sailors can use the long bamboo pole to support the boat. The huge penny three or four feet long, each of which requires the joint operation of several sailors, can be easily inserted into the rocks at the bottom of the river and quickly advanced against the boat. Each boat is equipped with at least four of these long pennies, as the so-called "one penny top three oars", in the mountainous water shallow river popular boat is much faster and much less labor-saving than paddling.

Zhou Tai, the deputy general in charge of the water war, was the first to sit on the first warship. Although these ships are light ships between the boat and the fighting ship, it does not affect Zhou Tai's confidence in dealing with sudden enemy situations in the slightest.

Day and night, they took turns to support the boat, and safely moved forward for seven or eight days, sailing out of more than 600 miles of waterway, and soon arrived at Muma County, a county town on the periphery of the Kunming Basin and close to the source of Tushui.

Zhang Fei and Li Su's army was not discovered by the enemy, and sure enough, Lushui was regarded as poisonous water by the local Nanban, and since ancient times, it has never been heard that a Han army will always follow the river to sneak attack, so the deep mountains and dense forests on both sides are not at all guarded.

In contrast, the biggest threat to Li Su's troops and even Li Su himself lies in the disease - although the Jinsha River and its tributaries cannot really be "poisonous water", and Li Su does not believe it, the reason why the natives say this must be reasonable.

Therefore, this poison mainly comes from mosquitoes, fleas, lice, mites and bacteria in the primeval dense forests on both sides and tropical rainforests. The able-bodied soldiers were bitten by some of the malaria mosquitoes, which were estimated to be carrying the malaria parasite, and a small epidemic of malaria soon spread among the army.

Fortunately, Li Su made a quick decision and ordered Zhang Fei to put all the sick soldiers on the same boat, and to isolate the sick and healthy soldiers in different boats.

But even so, malaria and other tropical diseases infected more than 10 percent of the troops, and at least seven or eight hundred people were infected after 600 miles. Hundreds of them were so seriously infected that the whole boat could not hold the boat, so Li Su had no choice but to promise them to go back downstream, or to give them enough dry food and clean drinking water, and let them find places with sparse mountains and forests on both sides of the river to station, and wait for rescue by themselves.

In fact, Li Su has already done a lot for this, otherwise the number of infected soldiers will probably be several times more, or even impossible to control at all.

"And the toilet oil? Wipe me a little more, no, I'm so hot that I scrub my body again, and I have to reapply the medicine. Li Su was lying alone in the cabin, panting for breath, but he had to continue to grit his teeth and insist, he knew that he must not fall short at this time, as long as he walked out of the tropical rainforest basin and entered the Kunming area, everything would be fine.

The soldiers carefully sprayed and smeared the precious toilet water prepared in advance in the army to ensure that Li Su, the core soul of the army, would not be bitten by mosquitoes, fleas and lice.

This flower water was also mass-produced by Li Su when he was making the final preparations for the Southern Expedition in Qianwei - not that he didn't want to prepare for a longer period of time, but because the shelf life of plant products in this era could not be guaranteed, and the essential oils of flowers and herbs were easily volatile and ineffective, Li Su could only start centralized production one or two months before the war, and it was put into use as soon as the production was completed. In addition, summer is the season when flowers, various resins, and tree sap are most abundant, and raw materials are also easy to use.

Li Su's flower water, he originally intended to imitate the later tropical wilderness artifacts "Wanjin Oil" and "Wind Oil Essence" to make it, but the three main materials needed for Wanjin Lump, camphor, peppermint and eucalyptus oil, can only get the first two now.

Camphor is native to Nanzhong, mint is Li Su before entering Shu asked Loulan Hu merchants from the Western Regions to buy, native to Persia, the late Han Dynasty is rarely planted locally by Han people. After Li Su entered Sichuan, in order to prepare for the Southern Barbarian expedition, he had a small amount of mint planted for military needs.

As for the core soul and eucalyptus oil for poisoning, eucalyptus is still in Australia today, and there is no great exchange of species in the Age of Discovery, and this problem is unsolvable. Li Su could not be like the Hakka people who colonized Nanyang in the late Ming and early Qing dynasties, and relied on panacea to eliminate tropical diseases.

However, the flower water without eucalyptus oil can also play about half of the insect and fever prevention effect of the gold balm, which is already a great benefit for the Han army, which originally had nothing. If there is no flower water, maybe half of the soldiers will really be on the voyage of "600 miles of water and water".

"I see the city! In front of it is Muma County! ”

As the adobe city wall appeared at the end of the field of vision, Zhang Feibu, who still had 4,500 people left to fight, and Li Su's personal soldiers, who still had 1,800 people left, all burst out with amazing morale.

After being bitten by insects for 600 miles, it's finally time to vent! Du Du is really a god and a man, such a road can carry a surprise attack, and the enemy army can be undefeated if he is defenseless!

"Boya, don't move, I'll come when I go, take the county seat and then take you into the city!" Zhang Fei saw that Li Su himself also wanted to struggle to get up, so he hurriedly pressed him and let him lie down, saying that he would leave the matter of using knives and guns to the third brother to take care of.

Zhang Fei's physique is much stronger than Li Su, so in the case of a supply of toilet water, a trace of mosquitoes can not cause damage to his health at all, and he even takes mosquito swatting as a pastime along the way, and has killed thousands of mosquitoes for fun in so many days.

It's finally time to kill people and vent instead of swatting mosquitoes!

Zhang Fei asked people to lead the horses, held the Zhangba snake spear and put on the armor, and then led the people and horses of the headquarters to attack the county seat of Muma.

The station ship originally carried a small amount of crashing wood and a few flying ladders, the key is that the broken county town of Muma, the earthen wall of the city wall is only one person high, and there is no defense at all - since ancient times, no one has come to attack such a remote city, and the Nanban is too lazy to waste a lot of people's power on building the city wall.

Therefore, outside of the two core counties around Dianchi Lake, Guchang and Dianchi Lake, the city walls of other counties are similar to the walls and fire sealing walls in the north.

Zhang Fei led the troops to rush down, not only was the city gate knocked open by the crashing wood, but even the city wall was directly knocked down by the trees, which was similar to hitting the courtyard wall, and then Zhang Fei jumped through the gap and started a street battle and brandished a snake spear to assassinate wildly.

"Run! Go to Weixian and Dianchi to report the news! ”

"Where did the madman army come from, and who called this?"

The county lieutenant of Muma and several of his commanders were scattered, and after dozens of soldiers were killed, they collapsed directly, after all, this place is usually the county lieutenant directly with the commander, and there is not even a Qu military marquis, and the troops are extremely weak. Jing Yi dispatched the main force to the mountain road battlefield in Weixian County, there were only more than 200 people left, how to defend?

Zhang Fei rushed along the main alley in the county town and took Muma County before taking Li Su into the city and asking him about his follow-up plans.

Li Su endured fatigue and illness and ordered: "Our army will continue to advance down the river first, divide the troops after leaving the Tushui River Valley, and immediately turn south over the mountains and turn into the Wenshui River Valley, take Kunze County, and block the retreat of the enemy army in Wei County to retreat to the Dianchi Basin."

On the other hand, taking advantage of the emptiness of the enemy, they directly took Guchang County and Dianchi County, and controlled all the rich lands of Kunmingyi. Let Wang Ping and Zhou Tai cut off the enemy's rear road with Kunze, and after taking it, camp on the road and don't engage the enemy. Yide, I will enter Kunming with you. ”

Li Su's hand, one is to block the enemy's main force to return to help and escape the road, the other is to stake the land quickly to grab real profits, and the later Zhuge Liang when he first came out of Qishan while frantically enclosing the three counties of Longxi, while sending Ma Tan to block the street pavilion to prevent Zhang He from crossing Longshan, is quite similar.

But the only difference is that this time Li Su asked honest and cautious people like Zhou Tai and Wang Ping to block the road, and without Ma Tan's kind of "camping troops in dangerous places on the mountain", Zhou Tai and Wang Ping should not have a problem blocking a river valley.

From the map, Kunze County, which blocks the outlet of warm water, is located on the west bank of Wenshui, and Wenshui also plays the role of a moat on the east side of Kunze. To block the entire river valley, Wang Ping and Zhou Tai only need one to guard the county seat, and the other to camp on the other side of the river in the east of the county, blocking both sides of the river, leaving no room for smuggling, and it is foolproof.

Li Su pointed to the map and briefly said this thought, and then said: "Camp strictly according to what I said!" Don't adapt and innovate by yourself, vainly seek danger to kill and injure more enemy troops, let's seek stability in everything, otherwise we will be killed even if we win! ”

"The last general obeys!" Zhou Tai Wang Ping listened to Li Su's detailed instructions and said that he would set up camp in strict accordance with the plan and never cut corners.
