The fleet needed to sail north out of this tributary of the Yellow River into the Yellow River, and then travel eastward in the Yellow River for about two days, and finally enter the tributary adjacent to the three cities of the Dragon Tribe in the north, and the whole journey took about three days, with a little faster downwind and a slower headwind.

The women who originally belonged to the Blood Tiger Tribe were the biggest helpers of the Dragon Tribe, a total of more than 240 people, divided into six groups equally, each batch was divided into five boats, under the command of the men of the Dragon Tribe, they would use the language of the Niu tribe to comfort and persuade the passengers on the boat.

On the five ships, the men of the Niu tribe took one boat alone, fifty men from the Niu tribe, ten women from the original blood tiger tribe, and thirty dragon tribe warriors, plus the boat pilots, the total number of people on this boat was nearly a hundred.

The boys between the ages of six and twelve in the Niu tribe were also on a single boat, with a total of seventy-five teenagers, ten women of the original blood tiger tribe, thirty warriors and boat pilots, and the number of people on this boat had exceeded one hundred and twenty.

In order to prevent accidents, the men and teenagers on both boats were tied with ropes, and ate and lazard in batches at regular intervals.

The remaining three ships are a mix of women, girls, and children, with an average of about eighty people, and the sailors and ten women of the original blood tiger tribe are standard, and the warriors are reduced to ten, and the possibility of accidents on these three ships is very small, and there are not many warriors.

Maybe it's the first time for the people of the Niu tribe to take a boat in the river, most of them are very honest, and even show a look of fear, and because it is the first time to take a boat, a small number of people have seasickness, seasickness will be seasick, anyway, it will not die, and it will pass.

Three days passed in a flash, and on the morning of the fourth day of sailing, the fleet slowly sailed into the Zhucheng wharf.

Knowing the return of the fleet, Lu Yuan came to the dock to understand the situation as soon as possible, as the supervisor of this fleet, Yue Rong handed over a letter written by Su Yan to Lu Yuan, from the letter, Lu Yuan quickly learned about the situation of this campaign.

Except for the sailors and half of the warriors on the five ships, the rest of the people stayed in Zhucheng, and the fleet replenished some fresh water and food in Zhucheng, and at noon, the fleet sailed away from Zhucheng and headed towards the Niu tribe's residence.

The fleet left, and Lu Yuan was still busy dealing with the personnel left by the fleet.

According to Su Yan's orders, among this group of people, women, girls, children and injured men were left in Zhucheng, and teenagers and uninjured men were sent to Yuancheng by land or water, and then sent to the copper mining area, where they were waiting for a long slave life, and those injured men were also sent to the copper mining area after they recovered from their injuries.

Although the woman stayed in Zhucheng, she couldn't deal with it for the time being, and she couldn't be picked up by the men in Zhucheng to go home now, and when Su Yan returned, she would reward the woman to the meritorious man, not only the man who went out to fight this time, but also other meritorious men in the tribe.

In addition, the women of the original Blood Tiger Tribe will not make arrangements, they are considered to have voluntarily joined the Dragon Tribe, if the previous spouse is still there, they can return to the previous spouse, if the spouse is not there, give them a year to find a spouse, if a year has passed and there is no spouse, the tribe will arrange for them.

After a little more than two and a half days, the fleet returned to the Niu tribe's residence, and after a short day of rest, the warriors of the one of the tuns on the ships stayed at the residence, and the other two tun warriors boarded five ships as guards.

This second leg was similar to the first, and when all the crew had boarded the ship, the fleet set sail.

On the shore, Su Yan watched the fleet go away, turned around and glanced at the Niu tribe's residence, two fleets, the number of people in the Niu tribe's residence decreased rapidly, up to six trips, most of the personnel will be sent back to the Dragon tribe, and the last trip will be used to transport cattle.

With the reduction of personnel, danger will also appear, once there is an enemy to attack the Niu tribe at this time, then Su Yan's situation will be a little dangerous.

Especially in the last few trips, there were not many people left in the Niu tribe's residence, and even if the warriors of the dragon tribe could defeat the enemy with one as ten, they would suffer heavy losses.

Time passed, a month passed quickly, and what Su Yan was worried about did not appear.

That's right, the enemy who dares to attack the Niu tribe will not be worse than the Niu tribe in terms of his own strength, but with the Niu tribe living as the center, it is difficult to appear such a powerful tribe as the Niu tribe within five days' journey.

When two tigers fight, one killed and one wounded, the powerful tribe will avoid waging war with another powerful tribe, unless that tribe has an overwhelming advantage and will not suffer too many casualties itself when conquering the other tribe.

Cattle were herded onto the boat, tended by the women of the original Blood Tiger tribe, and with the last warrior on board, the cow tribe settlement was empty.

This "emptiness" only refers to the fact that there are no people, and only part of the grain in the place where the cattle tribe lives is eaten, and most of the rest is left.

These leftover things are definitely a huge wealth for other tribes, but for the dragon tribe, the value is very low and low, there is no need to bother to bring it back, the valuable things of the cattle tribe are the population and cattle.

The flotilla departed.

Driving in the river, the cows in the cabin were a little restless, it was the first time they had such an experience, and it was strange that they could settle down.

The last group of women of the original blood tiger tribe who remained were more in contact with cattle, and the warriors were strangers in the eyes of the ox, but they were acquaintances, and they were comforted by acquaintances, and the restlessness of the big cow and the calf subsided a little, but they were still very nervous.

"It's over." Su Yan sat at the stern of the boat, looking back at the place where the Niu tribe lived, and there were many indescribable emotions in his heart.

After two years of preparation, a team of nearly 500 people, and an expedition, the Niu tribe was wiped out by the dragon tribe.

The purpose of the conquest of the Niu tribe is to obtain the cattle, the ox, and the dragon tribe to get it, and at the same time, to allow the dragon tribe to gain more population, and by the way, to get more information about the south of the Yellow River.

The destruction of the Niu tribe is just the beginning, in the month that the Niu tribe stopped, Su Yan has already formulated a new plan: to form two expedition teams, starting from this year, except for spring ploughing, autumn harvest, and winter time, the two expedition teams will take turns to set off with the fleet, conquer the tribes on both sides of the Yellow River and the regions on both sides of the Yellow River, and obtain population resources for the Dragon tribe.

The shipbuilding area also has to keep building ships, limited by the number of carpenters and rivers, the size of the shipbuilding area can only maintain the current level, build three A-type ships a year, and wait for the fourth city of the Dragon tribe to be established on the south bank of the Yellow River, and a second shipbuilding area will be established in the area near the fourth city, and more and larger ships will be built.
