After the people were strong and the horses were strong, the number of fire guns and copper cannons planned by Gu Yuan was completed, and the earth mines were also produced to the number of pre-built plans, and they were basically verified one by one. Only after the iron casing and wooden handle of the grenade were installed, the work of pouring gunpowder into it and setting off the detonating wire was not completed.

Because this is a highly technical job, it is not something that ordinary people can operate after learning it. Gu Yuan personally taught a group of people, and then this group of people taught the second group of people, and it was not so smooth in the middle. Some of them have spent twice as much time and energy, but they still haven't been able to learn, and they can't make qualified grenades, either duds, or gunpowder that doesn't explode, which is very dangerous!

Gu Yuan had no choice but to select people with good skills, and under his personal leadership, he worked overtime and overtime to manufacture, and in this way, when the original departure time of the expeditionary force arrived, in early summer, more than 800 pieces were processed.

"Okay! More than 800 pieces are enough to be used for a while, and there is no problem in fighting three or five battles! We can still make them on the road, bring those hundreds of wooden handles and iron shells, and gunpowder raw materials! Are there two thousand earth mines?" Gu Yuan asked his logistics company commander Wooden Stake.

The stake laughed "hehe", there were three thousand earth mines, half of them of clay pots, half of them iron.

"Yo he! The fire cannon is enough for five hundred, is there a hundred bronze cannons?" asked the Qiu Junshi in surprise.

"Six hundred fire guns, one hundred and five bronze cannons!"

"Okay! Select people to gather materials, set off after the third day, and go directly to sweep the Bahe Twin Cities!"

Gu Yuan gave the order for the expedition in high spirits! The Protoss people immediately got busy, and now there are more than 2,500 people in the entire tribe, excluding the people who live separately in the outpost, there are more than 1,800 people living in the Protoss Palace, and there are already more than 1,300 soldiers in the Shenwei Camp alone.

This time, Gu Yuan was going to take away an army of 1,000 rao and 200 villagers to live in the twin cities of Bahe in the future. The five companies became five battalions, five types of arms, reconnaissance, operations, logistics, communications, and guards, and each battalion had Sakura

The original headquarters of the battalion was also turned into the regimental headquarters, and the entire army was called the "Divine Guard Regiment". The more than 300 people who stayed at home were combined into the army, called the "palace defense battalion", shouldering the task of patrolling and protecting the family, and together with the brute dragon, giant birds, dinosaurs, and flying ants, they formed an iron wall to protect the palace of the gods day and night.

The old man in charge of the knife is the battalion commander, the night old witch is the military division, and the hunting and soil gathering are the deputy battalion commanders. Separately, they all joined the ordinary life and labor, some helped with smelting and casting, some helped with farming, some helped with hunting and gathering, and some helped with weaving and clothing.

The army set off, and Gu Yuan sent scouts within 50 miles of the front and back. Not only that, Gu Yuan also sent a flock of giant birds to carry 100 Qi agents, all carrying rockets, rushing to the Bahe River in front of their heads, stationed on both sides of the river, and first cut off the road for them to come to Hedong to rescue from Hexi Tucheng, as long as they saw someone coming out of Hexi Tucheng, the Yu agents took off into the air of Tucheng and shot rockets down.

Gu Yuan also deliberately arranged for the Yu agents to fly higher with birds, so that the bows and arrows on the ground could not be shot, and they just threw rockets downward in the air, without aiming at anything.

Without distractions, the march speed is naturally much faster. Within a few days, they arrived 30 miles northeast of Tucheng on the east bank of the Bahe River, and Gu Yuan ordered a large group of men and horses to be stationed on the spot and hide in a large valley. He only led 300 firebolts, bronze cannons, throwing teams, and bombardiers, and brought enough gunpowder and grenades to approach Tucheng.

Or march at night, let the brute dragons walk around, and the men and horses walk in the middle. Gu Yuan held a telescope with night vision to lead the way, and first quietly touched the big cliff in the northeast corner of Tucheng, which he was originally optimistic about, and set up ten copper cannons and ten powerful throwers on the cliff.

As soon as the light was bright, Gu Yuan sent a huge group of 500 barbarian dragons to the Bahe River to help the giant bird flock block the reinforcements of Tucheng in Hexi.

"Prepare - the first round of artillery fire and earth mines are intensively bombarded, covering every corner of the center of the earth city, release!" With Gu Yuan's order, the copper cannon barrel spit out a red-hot iron egg, and it poured into the center of the earth city like hail.

"Boom-" The dragonfly-like earth mine that lit the water exploded when it landed, and the people in the Tucheng tribe who had just come out of the thatched hut and had not yet woken up were blown to the point of flesh and blood, crying dad and calling mother, dizzy, and didn't know that they were hiding, and looked up stupidly.

"The second round of earth mines bombarded the city gate hole, prepare - release!"

"Boom-" Sure enough, it was able to hit the position of the two city gate holes, and only three or four earth mines on one gate hole collapsed, directly blocking the city gate.

"The bombardment team is ready to attack the city! From the two city gates, seize the top of the first earthen wall, and lie there to drop bombs and launch rockets will achieve the best results! Attack!"

Gu Yuan raised his binoculars and saw that the Tucheng people began to assemble, and a leader and a wizard came out, leading people to prepare to go up to the city wall to organize a counterattack. It was too late for them, and several of the warriors guarding the city walls were shot by the Divine Guards as soon as they showed their heads.

The battalion commander of Bigfoot led the bombardment team to crouch on the first earthen wall of Tucheng, that is, on the outer slope of the outer wall, and looked down and gasped. There are more than ten meters wide between the two walls inside and outside, and it is impossible to jump over, and the bridge ladder cannot be put over. It's not just that, the main thing is the depth, and looking down is a trench dozens of meters deep.

"Obediently, isn't this a line when you look up from below? Can you bury the dead without fear of landslides when digging?" thought to the battalion commander of Bigfoot, looking at the ancient command flag on the high cliff. Because the outer wall here is lower than the inner wall, only the upper part of the inner wall can be seen on the outer wall, and the human head can not be seen, and the situation in the city cannot be seen.

You can see it from afar, and with the help of a telescope, you can see it very specifically and meticulously, and you can see many subtleties in the corners. Seeing that the warriors of Tucheng had gathered at the foot of the inner wall and were about to go up the wall, Gu Yuan ordered the flag to be unfurled, ordering them to drop bombs immediately!

"Boom-" "Boom-" This is miserable, the Tucheng warrior who just climbed to the dirt slope was suddenly smashed and blown up by a burst of unknown things flying down from the top of his head, and the head was broken and bleeding was slightly injured, and the flesh and blood were flying sideways to death!

I don't know who was blind and shot so accurately, and a grenade blew up the leader and the wizard together. Bigfoot led a flurry of grenades thrown in, and then withdrew to guard the outside of the city gate.

At this time, Gu Yuan could see that the Tucheng was already in chaos, and the warriors were also dead, but only a few grass huts were on fire, and most of the grass hermitages were still hiding people, there were about eight hundred people in them, and more than half of them should be hidden.

"Agents have attacked, fired rockets, cleared their dwellings!"
