There are four counties in Liaodong, all within the sphere of influence of the Gongsun family.

Liaodong County located in the Liaodong Peninsula migrates from the northern part of the Korean Peninsula to Xuantu County in the northern part of the Liaohe Plain, and Lelang, located on the southeast coast of the Korean Peninsula, and two counties in the Daofang.

It can be said that if you don’t have confidence, you won’t fight. The entire Liaodong still has a certain strategic depth. After all, the Wei army came from a distance and walked thousands of miles. Running inside can further lengthen the Wei army’s front line.

Stop until winter or spring next year and wait for the times to change.

To this end, Gongsun Xiu wanted to solve the upcoming surge in the river. He mobilized the people's efforts to clear the rivers and expand the rivers in Xiangping. He also dug a drainage waterway in the city to prevent the surge in the rivers and give the Wei army an opportunity to take advantage of it.

Historically, the July River rose sharply and the water level rose, flooding the Yan and Wei troops. The water flooded the plains and the water was nine feet deep, surrounding Xiangping and blocking the water. The Wei army's grain transport ships could run directly in the water, which was also the reason why Liaodong was defeated very quickly.

To this end, he recruited the people of Liaodong to repair the river channel. The diversion of the diversion ensured that the entire Xiangping City was safe and sound before the July heavy rain came.

Not only that, in order to prevent food outages, we also raised food and grass five months in advance to avoid the scene of people eating after siege.

In fact, Gongsun Yuan did stock up on sufficient food and grass. In the end, the root cause of the encirclement of the encirclement was that he was attacked by Sima Yi's plan to attack the east and west, and brought the main force of the Liao Tunnel into Xiangping without carrying the baggage. It turned out that sufficient food was not enough to eat at once.

The Yan army set up defenses along the Liao River coast, facing Sima Yi across the river.

Gongsun Xiu could not think of what Sima Yi would do next, and he would not do it if he couldn't figure it out. Consolidating his own strength was the most important thing.

He looked along the Liaoshui River for a long time, and Bei Yan led his personal army to approach and said in a deep voice: "Criminal, you have discovered the Wei army's food route."

Gongsun Xiu thought: "Is it on the sea?"

Bei Yan nodded: "The prince Mingjian, the Wei army's food route came from Liaokou."

Sima Yi's march route came from the sea route, through Guzhu, Jieshi and other places. From the map, he almost ran to Liaodong along the coast.

The road to the sea is extremely dangerous and is a shortcut to Liaodong.

In 207 AD, when Cao Cao was expeditioning to Wuhuan, his march was not on the sea route, but on the farther Lulong Road. Although Lulong Road is easier to walk, it is also extremely dangerous. Cao Cao's army was almost wiped out due to lack of food and water. Hundreds of miles were deserted and deserted, and there was no source of water even though he was chiseled twenty feet away.

With these natural barriers, Liaodong was able to be independent of the Central Plains.

Gongsun Xiu frowned when he heard that the grain route was transported from Liaokou to Liaodong, "Does our army have large warships?"

Bei Yan said: "There are only small boats, but no big boats."

He thought of the lightning and asked, "How small is the boat?"

"It's basically three feet tall, about sixty ships." Bei Yan replied.

Gongsun Xiudao: "We sent ships to harass the Wei army's food route, forcing him to save himself."

Bei Yan said: "Don't you plan to go hand in hand with water?"

Gongsun Xiu shook his head: "Turn Sima Yi out first, and it is useless to go through water and land."

When he led his army to the dock of Liaoshui, sixty ships were moored there in scattered shapes.

Gongsun Xiu was stunned and said speechlessly: "Is this your small boat warship? It sank after being hit by the Wei army. How can you resist?"

Bei Yan smiled bitterly and said, "There is only such a ship in Liaodong."

Gongsun Xiu was speechless. How could he launch a decent naval battle? He immediately said, "Is each boat moving fast?"

"The speed is OK, but it is easy to fall apart when there is a collision."

Bei Yan glanced at the hull, "It will be destroyed when it hits, it is relatively weak."

Gongsun Xiu jumped onto the ship and ordered his soldiers to run the ship. He found that although the ship was only three meters long, it could accommodate nine people. It was extremely convenient to operate and turn around, and it was much more flexible than a bulky big ship.

In ancient times, naval battles were basically based on equipment. For example, the tower ship was an ancient aircraft carrier with a huge hull and more than ten feet high. The three-fold building was built on the ship, the women's walls were arranged, the battle grids, the banners, the windows were opened, the spear holes were opened, the throwing carts were placed, the stones were built, and the iron buckets were shaped like a city turret.

The smaller one is the hunch. The hull is very narrow and long, with strong mobility, which facilitates conflict with enemy ships. This ship "covers the ship with raw cowhide, opens the snatch holes on both sides, and has crossbow windows and spear holes on the left and right, front and back. The enemy cannot advance, and the arrows and stones cannot defeat them."

Of course, naval battles are projecting weapons from far to near, until the two ships collided, and the weak one destroyed the shipwreck. If both sides strengthened each other, they would fight each other directly on the deck.

When Gongsun Xiu's Yan Army Navy faced Cao Wei's navy, there was basically no difference between a small sampan, and it broke up after a collision.

He had a sudden inspiration and suddenly said, "There are eight pulp handles under the ship, and sixteen wooden pulp are flying. Working together can make the ship come and go like the wind. The warship is equipped with a strong body, and it can harasse the Wei army's food route by firing the extremely lethal arrows. Even if it cannot be conquered, it can harass Sima Yi and the right side will be clumsy."

Once the bed crossbow was quoted, it became very useful. The Yan army called it "Potian Yan".

Bei Yan also felt that this was good, and nodded and said, "That's not bad. It's far from the sky, so it's not difficult to break through the tower."

Gongsun Xiu laughed and immediately ordered people to equip Potianjian onto the warship. Potianjian was slow to manufacture, with only thirty-five warships, so they could only be equipped with thirty-five warships.

He selected nearly four hundred soldiers who were good at water, and hung up flags and named them "Ambassisted Battleship".

At the third update that night, Gongsun Xiu personally led a warship around the sea to Liaokou.

The Wei army established a dock at the entrance of Liaokou. A large number of civilians transported food and grass at the dock, and rushed to the battleships in a row to form a huge dock.

The endless stream of food and grass was unloaded from the cabin, and truck after truck was transported to Sima Yi's camp.

The sea-surrounding warships were sailing scattered on the huge sea surface. Before Gongsun Xiu could get close to the dock, he was spotted by Wei Junshi patrolling nearby waters.

As soon as the Wei army discovered it, they immediately beat the drums and horns. Seven or eight ships rushed around. The ship was brightly lit and prepared to encircle and annihilate the small boats.

Gongsun Xiu shouted: "Retreat all, fire arrows, and do not be surrounded by the enemy."

At this time, the advantages of the sea-surrounding warship were reflected. The small sampan was extremely lightweight, quickly turned the bow of the ship, and rushed towards the Wei army's stern.

"How dare you come to rob the food road with more than thirty broken ships?"

In the dock, the long-bodied civil servant was a little funny. He walked to the deck, looked at the small boats on the sea, shook his head and said, "Everyone stopped, one by one, sinking."

This person is named Wang Chang, and he is the escort officer of the Wei army. He is responsible for logistics and supplies and other matters. He is almost in line with Sima Yi's army's departing.

Logistics is an extremely important item in military wars. The so-called "before the troops and horses move, food and grass will lead, and the 40,000 Wei infantry and cavalry army that drove all depend on the baggage troops for food, clothing, housing and transportation.

To be honest, tens of thousands of troops died in battle, and the war could continue to fight. If the baggage, food and grass troops were intercepted, the army of tens of thousands would be hungry for three or five days.

Attacking the baggage troops in the rear is almost the same as directly attacking the enemy's camp.

The navy of the warships around the sea began to turn the winch, rolled the arrows on cotton cloth, poured tinder oil on fire, and a loud "collapse" sound. The arrows snailed flames and shot a nearby ship near the rushing, and the bow of the ship caught fire.

The Wei army hurriedly carried water to put out the fire, and the ship was in chaos.

Wang Chang's face changed color by the arrow and said strangely: "What kind of bow is this? It can actually shoot hundreds of steps?"

No matter how the catapults of the Wei soldiers were, even the feather arrows could not match the opponent's ships, the crossbows equipped on the Yan army were so fierce that they not only had a range of 700 steps, but also could break through the solid walls of the ship.

Thirty-five sea-circling warships were equipped with a crazy launch, and each arrow was sank, causing the Wei army to run away with its head in its arms.

Wang Chang was frightened to see it, and stood at the bow of the boat and shouted loudly: "Scatter and surround them. The boat cannot withstand the collision, and surround it and do not follow it."

He saw the power at a glance, and if he followed behind, he would only become a living target.

At this moment, a bolt arrow flew towards Wang Chang.

The personal soldiers beside him hurriedly pushed Wang Chang away, but the personal soldiers had no time to dodge. The arrows drove him away several feet away, nailed them to the side of the ship, and the body was ignited with flames.

Gongsun Xiu cheered, and as he saw the pursuit of Wei army began to disperse and unfold in a semicircular manner. If he was allowed to surround the sea, the warships around the sea would have no advantage.

The strategic goal of harassing the Wei army's rations was achieved. Gongsun Xiu no longer fought and led his troops to evacuate. At the same time, Potianqi kept shooting continuously. Potianqi fired extremely slowly. It took more than ten minutes from turning the winch to pull the bowstring, loading the arrows, and then aiming and launching. Fortunately, the range was very long, and the boat kept a certain distance from the Wei army's rushing battleship, so it was not surrounded.
