At this moment, on the street not far from the gate of Jinzhou City to the north, there was a platoon of combat sappers who were laying several prefabricated traps in the place they had chosen.

The most important of these is a kind of chain trap.

Among the bluestone slabs that littered the street, several pieces had been lifted, and the dirt road underneath, which had been tamped, had been dug up into large holes, and a large number of explosives had been placed in the potholes.

The fuses used to fire these explosives are taken from the flint fuse mechanism in the style of stepping on mines.

After the explosives and fuses were planted, on top of the hole that had been dug up, several thin planks sawn from relatively crunchy wood were erected, and on the top layer was a bluestone slab that had been faintly cracked.

The load-bearing capacity of this trap planted on the avenue is very low, and anyone who steps on the bluestone slab that has been passive will definitely fall down and step into the hole below, and then trigger the flintlock mechanism to ignite the buried explosive bag.

Of course, the trap that will be specially made by combat engineers cannot be so simple, if it is only this level of simplicity, ordinary soldiers of the Huaxia Army can complete it, why do professionals like combat engineers need to take action.

In fact, it was only one of a series of traps, and a large number of explosives, black powder, and ignitions were planted under several other stone slabs connected to the pits with flint fuses, or in the gutters on either side of the street, or even in the houses on either side of the street.

Between this series of things, there are several different routes of primers connected together, and they can all pass through the most critical node to detonate in a chain.

At the same time, also to be on the safe side, the trap would not work due to the temporary failure of the pressure device, and several of the ignition devices in the center were placed by the combat engineers.

This series of blasting arrays connected together is a relatively large trap in Jinzhou City, the amount of gunpowder has reached more than 100 catties, and there are about 10 catties of new explosives during the burial period, after the instant explosion, the energy that can be triggered is absolutely amazingly powerful.

This kind of serial trap was copied out by the combat sappers from a series of military books bought by the Ministry of Military Training from the Ming Dynasty, and after many experiments by the combat sappers, there are now many special units that have fallen in love with this powerful serial trap.

A large part of the members of the combat engineers are bombers drawn from the mines opened in various parts of China. These miners, who were born in the mines, were quite familiar with the use of explosives.

The trap now laid by the combat sappers was the last trap they had laid in the Golden State City. The staff officer of the brigade headquarters ran over and carefully noted the location of the trap on the map, and several scouts in charge of the broken rear also mounted and entered the urn city.

Since then, there has been no one in the entire Golden State City.

Two scouts circled the city from the side, rushed in through the southern gate, and came to Zachdan, who was standing in the middle of the urn city, and reported, "Report to the brigade commander, the Houjin Tartars who came out of Fuzhou, the forward cavalry unit, have arrived at the landmark 5 kilometers away. ”

Zachdan turned his head and looked at Jinzhou City, which was hidden in the dust and mist, and continued to ignite bursts of black smoke, looking hazy, and then asked the staff officers beside him, "Have the people and the last batch of non-combat troops boarded the ship?" ”

"Brigade commander, rest assured, they have been arranged to go to the small dock to board the ship a few hours ago, although there is no definite news yet, but they are only a few hundred people in total, and they must all be on board now."

Zachdan took out his pocket watch and looked at it, nodded his head, and without hesitation, he clipped the horse's belly and gave the order: "Then it's our turn!" ”

Two companies of cavalry, together with the brigade guard company, followed Zachdan and rushed out of the southern gate. More than 600 cavalrymen galloped out with the rumbling sound of horses' hooves, and they were the last remaining forces in Jinzhou City.

A dozen scouts remained in the urn city, poured fire oil on the materials that could not be moved, and then threw a torch on them, burned all the supplies, and then chased the cavalry army.

······

The cavalry behind the palace of the First Mixed Brigade of the Huaxia Army, which had been recuperating for a long time, was slowly walking on the avenue, and after marching about 6 or 7 kilometers, the first batch of Houjin Army forward scouts had already appeared behind them.

They hurriedly pursued the troops behind the Huaxia Cavalry Palace, and then, probably knowing that it was impossible for dozens of scouts to shake the formation of the hundreds of Huaxia cavalry in front, they began to follow from a distance.

Zachdan personally led the team behind the palace, commanding two companies of cavalry soldiers to keep the formation tight, and then evacuated in the direction of moving away from the enemy in alternate cover.

Along the way, they were constantly blocked by mine explosions, and the Jin army, which had walked for one day and two days, immediately understood what was going on when they saw the fire everywhere inside and outside Jinzhou City.

This time, they had carefully planned for a long time and spent a lot of effort on the surprise attack, which had completely failed.

The Houjin Forward Cavalry Troops, along the way, were constantly frightened, afraid that they would be blown up into the sky by a mine that suddenly exploded from the ground, and they had already held their breath in their hearts along the way.

At the front of the team was a red-flag-inlaid Ala-ezhen under Yue Tuo's command, who led the 500 Bayala and Jia's soldiers who belonged to the red-flag, and chased closely all the way.

And the cavalry of the Huaxia Army also launched a part of the rangers behind, and the cavalry of the Houjin Army who were in hot pursuit, rubbing and testing each other.

There was already a smoky scene near Jinzhou at the moment, and when I looked up, I could find that in everyone's field of vision, everything had a hint of haze. Therefore, Zachdan and his scouts, falcons, etc., have no way to accurately judge the number of Houjin cavalry that follows after birth.

So, on the orders of Zakdan, the entire cavalry detachment withdrew from this area at a slight acceleration. And the horsepower of the Houjin army, which has been running for two days in a row, is far worse than that of the Huaxia cavalry, even if the Houjin army desperately pursues, it can't completely stick to the Huaxia cavalry who has not completely let go of the speed.

The two sides chased each other one after the other, and ran a distance of 6 or 7 kilometers.
