"I haven't thought of it yet, but when they build it, I guess there will be a way!" Zhao Tianyou had an idea in his mind, but he still sold Guan Zi and didn't say it directly. The power of the Thunderbolt is still limited, and it needs to shoot projectiles to hurt the enemy, not a real kinetic explosion, and the effect is much lower when it encounters a building car made of logs.

If you use dozens of thunderbolts to destroy a building car, the price to pay is too great, and some gains are not lost. As long as there are people with wood, the Yuan soldiers can build building cars at any time, and for the consumption of gunpowder, such a result is not cost-effective.

And the same problem, Wen Tianxiang, who is far away in Zhangzhou City, is also worried about this. After Zhang Shijie withdrew from Quanzhou, Pu Shougeng needed to reorganize the endgame of Quanzhou Port, and he had no intention or ability to participate in the Yuan soldiers to continue to move south, and at this time, Suoduo's 30,000 cavalry became the main force of the Yuan soldiers on the land route of Fujian.

The memory of the massacre of the city in Tingzhou is still fresh, and the new hatred and old hatred are unforgettable, but it is still suffering from the lack of large-scale cavalry, and it cannot become an effective deterrent to the Yuan soldiers, so it can only rely on the high city wall to defend Zhangzhou, and cannot take the initiative to attack.

Suo Duo led the main force to attack Xiamen and Ludao, and the local militia was organized to resist together with the Song army stationed there, because of the complex terrain and stubborn resistance, the war fell into a stalemate. Dong Wenzhi led an army of 2,000 yuan to patrol and guard along the coastline, beware of Zhangzhou sending troops to rescue Xiamen.

There are soldiers and no horses in Zhangzhou, and the warships of the Canghai County Navy Division have also scattered and fled, and there are only some fishing boats in their territory, and their combat effectiveness at sea is even weaker, and the threat to the invading Yuan soldiers is very small. Dong Wenzhi led his troops to inspect in the direction of Zhangzhou, and after burning two villagers who did not hide in time along the road, the burning and slaughter of the people rose up, and then he simply led the army straight to Zhangzhou.

Outside the city of Zhangzhou, there are uneven roads everywhere, and the Anshan ravines and small rivers are intertwined, which is very unsuitable for large-scale charging operations, and it is very easy to hurt the war horses by galloping. Dong Wenbiao didn't care at all on a whim, when there were still ten miles to Zhangzhou City, more than 100 injured horses had been left along the road.

Zhangzhou City received a report of the enemy situation early on, and the people outside the city had been evacuated.

"Lord Wen, the last general is willing to take five hundred soldiers to the black pine forest to ambush, give the attacking enemy a dismount, and rob them of some horses by the way!"

Wen Tianxiang said with a smile: "General Qin, the scout reported that there were two or three thousand cavalry soldiers, and you brought five hundred soldiers to ambush, is there a little less?" We have not been idle in the past few months, the three craftsmen have been working hard to create new firearms, if we are afraid of these two or three thousand yuan soldiers attacking, we will all jump into the sea and commit suicide.

Pass on my general's order, General Qin Song led five hundred god-armed crossbowmen to ambush on the left and right sides of the black pine forest, remember to shoot only people and not horses! Su Yong listened to the order, you take five hundred sword and shield men to cover the flank of Wuhupo, drive away the Yuan soldiers who are chasing and killing the stragglers, and you can't let go of one. I've already set up an ambush in these two places, you just do your job, and don't worry about the rest! ”

The two generals were ordered to leave, and Wen Tianxiang then made many arrangements. This half a year was spent on preparations, and if some arrangements were not made in advance for the two transportation arteries in front and behind Zhangzhou City, wouldn't it be a waste of the hot labor of the military and civilian people in the city.

Qin Song and Su Yong, the two generals, were originally Deng Huaiyuan's cronies, and Wen Tianxiang had a lot of whispers at the beginning of his takeover, but Wen Tianxiang laughed and passed, and he didn't bother with these two people. But today is an important matter related to the defense of the city, and it is related to the heads of the 80,000 soldiers and civilians in Zhangzhou City, Wen Tianxiang has to be a little more vigilant, and some military preparations have been concealed from them, and he is ready to talk to the two of them after today to unravel the past matter.

"Report to Lord Wen, the Yuan soldiers have crossed the water from the shallows of the Min River and have already gone up to Sanfeng Mountain! There are still five tiger slopes and eight miles away! ”

"Okay, send a signal to prepare, the Yuan soldiers have crossed the Min River, and all walks of life are preparing for war!"

Under the governance of Wen Tianxiang, the city of Zhangzhou was well organized, mobilized the strength of the whole city to learn and produce gunpowder, absorbed thousands of apprentices, and made thunderbolts and thunderbolts. The three craftsmen left by Zhao Tianyou were originally highly skilled, and with the unselfish teaching of skills, they soon accepted many talented apprentices in Zhangzhou City.

Some of Zhao Tianyou's design schemes, drawings, ideas, etc., were all things that his craftsmen had to discuss every day, and it was the same style in Zhangzhou, where everyone discussed and studied together, and worked hard to optimize and improve the existing technology.

With a mature basic technology, there has been a small breakthrough in the deep processing of gunpowder in Zhangzhou, after multiple experiments, adding specific metal ore powder will greatly increase the power of the explosion. Perhaps it was this open learning environment, the gunpowder workshop with the participation of thousands of people, that evolved into different functions and designs, and of course the mines used for ambushes were an inevitable product.

Wuhu Slope has five bends in a row, which is a ramp formed by natural rainwater impact to descend the mountain, and later after manual trimming, the slope and road width are slowed down. On the left and right sides are slopes several zhang high, but there are no lush woods to hide a large number of troops, so after Dong Wenshan looked at the terrain, he ordered the cavalry to dismount and carefully walk around the corner.

"The first batch of 300 people, go down to the bottom of the slope and cover the formation!"

Rao is Dong Wenzhi is full of confidence, and he looks down on the defenders of Zhangzhou in his heart, but he is also very cautious under this terrain, and first sends 300 people down to cover the brigade. The three hundred men went down quickly, and found nothing along the way, so they immediately informed the group on the slope to leave.

Dong Wenzhi led the rest of the cavalry to dismount, led the reins of the horse and walked downhill, along the way people shouted and talked about the neighing and laughter of the horses, and talked very indulgently about how to play when they caught a woman, and how to torture and kill a man when he caught him.

Su Yong's more than 500 sword and shield men were ambushed on both sides of the road below the slope, looking at the three hundred cavalry who came down in advance, Su Yong muttered in his heart. The place where I ambushed me is not bad, it is very hidden, but how do you fight the enemy after you go out?

Not to mention two or three thousand cavalry, just in front of the three hundred cavalry bending bows and arrows, there is not much left of my five hundred sword and shield men rushing to the front, what to fight with the main force? also asked me to follow and cover up, could it be that Master Wen has always been at ease with me, worried that I will not accept his complaints, and specially sent me to die!

After pondering it like this, I thought of Qin Song's ambush in the black pine forest not far away, could it be that our brothers are a fate, and they are regarded as a thorn in the side by Lord Wen, and the hand of the fake Yuan soldier sent us back to heaven!

At this time, the Yuan soldiers had already dismounted and entered the ramp, and a spark rose from a weedy pile on the side of the road, swimming forward in the grass like a thin snake.

"Squeak...... Syllable! ”

A rattling arrow flew into the air and exploded, flashing a silvery-white light.
