The rest of the Yu agents took off the bird and set fire down from the air, and the resistance was already very rare and weak, there were so many archers shooting arrows into the air, because the giant bird flew high enough, their arrows flew to a height of several meters away from the big bird and fell, and they couldn't even touch the giant bird's feet!

The fire soon burned, and the smoke billowed out of the city, and it was estimated that the smoke and fire were burning, and choking could choke some Tucheng people to death. Sure enough, soon there were old people and women kneeling on the ground and kowtowing to the air, looking pious, as if they were begging to surrender, begging to stop fighting!

"Stop the attack! Hungry the three of them, then dig the city gate and order them to come out! Now, let's go and clean up the people in the Tucheng City in Hexi!"

Gu Yuan led the people to retreat from the cliff, the bronze cannon and throwers were still left on it, of course, leaving the gunners and throwers to guard, and a flock of giant birds on the surrounding trees to help.

As soon as Gu Yuan arrived at the Bahe River, he saw that the other side of the river was in shambles, with ten giant birds sacrificed, six brute dragons glorious, and four Qi agents injured. Gu Yuan was a little distressed, and took a look at it again, the buffalo and hippopotamus in the water and on the shore were killed and injured countless times, and some were being decomposed and eaten by the brute dragon.

This is a war of different scales, no need to ask, the tribesmen in Hexi Tucheng have come out, and they are trying to help the people of Hedong Tucheng to flank the Protoss before and after, just like the last time. Unexpectedly, this time they didn't even cross the river, they were beaten severely by a group of brute dragons, a group of giant birds, and the people who drove the birds, and rolled back to their Hexi Tucheng in disgrace.

"Queen, carry me across the river, I will destroy this tribe, and at the very least, I will kill all their adults who can wield weapons, and not a single one will be left!" After Gu Yuan led the men and horses to cross the river, they had brute dragons and wooden rafts, and it was easy to cross the river, and when they went to the shore, they could see one or two dead people from time to time on the way to Tucheng, all of whom were strong warriors. Undoubtedly, they were all killed by the giant bird or the Monkey agent.

There was still smoke rising from the city, and the fire set by the agents had not yet been extinguished.

"Siege the city, chief?" said the commander of the Yan battalion indignantly.

"No! We can't afford to lose a single casualty or soldier! We don't need a single high-powered firearm, because there is no commanding height, we can't hit the city under the dirt slope, and we can't throw grenades, it's too far away!"

"What then? Send flying ants to destroy them!"

"I don't want to kill them all yet! It's still useful to keep a few children!"

"So? this...... How will this battle be fought?"

"Fight well! Dig the embankment, flood the earth city with water, and drown them!"

Autumn, smoke, clouds, and soil were happy when they heard Gu Yuan's words! This trick is too amazing! It's just that digging up the embankment is not easy! Gu Yuan looked at the embankment of the big river and smiled: "It's not too difficult! Manually dig out more than half of it first, and hand over the most difficult and dangerous places to the brute dragon! They can climb the embankment without being afraid of the water rush!"

While all the more than 200 people who had followed him were concentrating on digging the river embankment, Gu Yuan ordered the Yu team to take a bird to inspect the sky above Tucheng in Hexi. As soon as the team flew over the earthen castle, they saw a lot of arrows shooting upwards from it, but they fell before they reached the height of the birds.

When the agents came back to report that nearly a thousand people had gathered in the city, they were scattering and climbing up the slope of the city wall, which was organizing the defense of the city. Gu Yuan didn't have anything more on the surface, but in his heart, let's lie down on the slope and cool down!

"Chief, there is no need to dig the embankment with a dragon plow, although there is not much danger, but it is not fast enough, and if it is not fast, the river will not have much impact, and the destruction force of the earth city will not be too great! Rou whispered to Gu Yuan, now as long as there is no special task, Rou will sit in Gu Yuan's arms, like a good girl who is always coquettish in her father's arms. Now wearing a tights made of grass-green soft thin cloth, her bumpy body is even more exquisite!

"Okay! That's a good idea! Why didn't I think of it? The demolition team attacked, planted earth mines on the river embankment, and then detonated the lead wire!"

"Boom boom" a few loud noises, a bang, the river embankment will burst, the surging river water for thousands of miles, has been poured into the Tucheng in the west of the river, in an instant the Tucheng ghosts cry wolves, chickens fly and dogs jump, more cruel than when the fire burns. Originally, the water and fire were ruthless, and this earth city was as if it was deep in the bottom of the earth basin, and the two city gates had no time to escape from the outside.

When the water overflows half of the earthen walls of the earthen city, the water level is considered to be equal to the surface of the river. At this time, Gu Yuan sent agents to drive birds to reconnoitre, and almost all they saw were dead bodies, floating all over the center of the city, including rao and livestock.

"Report to the chief, you didn't live up to your hopes, most of the people drowned were women, children, and the elderly, and most of the samurai of the tribe who survived climbing the slope of the earthen wall. We saw the leader with brocade feathers on his head beating a young man with a shuttle pole on the dirt slope, but we didn't see the old wizard again!"

"Hey! This brutal guy is quite lucky, and he is not dead! Now every hour, a burst of rockets will be released in the air, and the agents will attack in turn! It is also the same method as dealing with the people in Hedong Tucheng, trapping them to death!"

The army of the Protoss was stationed on both sides of the Ba River, set up a fire to cook, and collected all the meat of hippos, donkeys, mules, and buffaloes. The remaining meat was then made into bacon and stored as military rations.

There was no movement in one or two, and when it came to the third, the people in the two earth cities couldn't stand it. Although there is still food and drink in the Tucheng City in Hexi, there is no place for people to stand. It is difficult to stand on the dirt slope, so you can only sit or lie on your stomach, and you keep sliding down. And there is no food or drink in Tucheng in Hedong, at most there is only one food, the second is starving, and the third is a little difficult to support, and you can't even drink a drop of water, what will it feel like?

Gu Yuan ordered the guards below, the people of Hexi Tucheng only left children under the age of ten and young women, and no one else left, as for the leader, he would kill him if he showed up. As for those in Tucheng in Hedong, as long as they come out to surrender and express their submission to the Protoss, they will accept it.

Early in the morning, the people in the earthen city in Hexi put long wooden strips or long bamboo poles on the trench between the earthen walls, and one person pulled it on his head, and the other climbed down from it. Astonishingly and comfortingly, the brutal leader, while crawling over the wooden bar, fell down and fell so hard that he could not die again!
