Time passed little by little, and the sun gradually set. The Liang soldiers and generals on the ship still stared at the shuttle boats and bamboo rafts parked on the island beach in the distance without blinking.

Suddenly, a soldier who was responsible for looking at the scene whispered: "It's moving, it's moving. Mahan's ship has started to move again." The general squinted his eyes and tried hard to look at it. Sure enough, he saw several Mahan ships as small as small black dots starting to move slowly, and then the other small black dots also moved, and these small black dots became larger and larger, obviously coming in their direction.

The general immediately ordered: "All members retreated into the cabin, and their status was changed to full diving in the hull!" Then, three or four people on the deck went down from a small hatch into the cabin, and then pulled down the entire piece of bronze cast and wrapped in a rubber ring heavily. Then, the entire hull quietly sank under the sea.

However, the ship still did not really dive to the bottom of the water. The place where the mast was originally upright was exposed, a thick metal tube painted in blue was exposed, two feet above the water surface and one foot in diameter. A head was exposed leisurely from the metal tube and continued to look in the direction where the Mahan ship came.

Daliang can only build such primitive submarines, strictly speaking, semi-submersible ships. The existing technical conditions cannot provide a hull that can withstand sufficient water depth pressure, cannot be suspended in the water to any position, and there is no condition to make a periscope that can truly see the scenes of dozens of battles ahead. The bronze-sharpened mirror will blur the scenery after several refractions. But in this era, this kind of semi-submersible ship has extraordinary significance both in tactical and strategic.

Su Shan Duli's fleet passed by more than 70 metal copper battles, but no one could find the object that looked about the size of a melon seed in the waves in the distance. In fact, in the eyes of Liang Jun's semi-submersible ships, these Mahan ships only sank and floated on the distant sea like a duck egg.

While observing the direction of the enemy ship, the Liang army's observation soldiers whispered to the generals in the cabin. In the cabin, eight soldiers began to pedal the oars and pushed the semi-submersible ship forward slowly, and then the speed became faster and faster. The helmsman held the rudder and kept adjusting the direction under the command of the general.

The Mahan army's bamboo raft was full of hot bombs deliberately discarded by Liang's army, and was traveling against the wind, so the speed was no faster than the Liang army's semi-submersible ship when it was stealthed in the water and all "manpower" was started. In this way, the Liang army's semi-submersible ship could bite the Mahan army's fleet tightly.

After 30 or 40 miles of sailing, the Mahan army fleet finally arrived at the coast of the area where Chaoxia Valley was located. Instead of landing directly, they entered a fjord extending to the hinterland of this land.

On the semi-submersible boat, the lookout soldier whispered to the cabin: "Boss, they have entered the fjord! The direction is two or three points!"

The general immediately said to the helmsman: "Follow up at two points."

At this time, his deputy who had been drawing on the table immediately said: "Boss, wait, this fjord is not marked on the chart, we are not familiar with the water. Is it too risky to go in!"

The general gritted his teeth and said, "We must take this risk!"

Soon the cylinder that surfaced was surrounded by weeds and branches, and soon entered the fjord, continuing to track Su Shiduli's fleet from a distance dozens of battles.

After about half an hour, Su Qiduli's fleet turned into a river again. When the semi-submersible lookout soldiers reported the news to the cabin, the deputy next to the general said again: "Boss, we can't follow us anymore. You know, our ship cannot sneak into the river, and the river is likely to be winding. When we enter, the lookout soldiers will find it difficult to observe the state ahead. If they don't do it well, they will be discovered by the other party, and then all their efforts will be wasted."

The general commanding the semi-submersible boat was silent, and the deputy pointed to the map on the table and advised: "Boss, we can basically determine the general location of their nests now. This land is actually an island surrounded by water on all sides, covering an area of ​​dozens of miles. They entered the river and went upstream, and it was unlikely that they would return to the sea through other waterways. Therefore, their nests must be hidden in the mountains of this land. We only need to report this news to the upper peak, even if we make great achievements. If we are greedy for me, we will be beaten up and all our previous efforts will be wasted!"

His words immediately convinced the general to make up his mind. The general waved his hand and said, "Retreat! Go back quickly and report to the top of the peak! Be careful when retreating, and don't let the enemy's secret whistle scouts notice it!"

There was a rustling sound from a bush on the coast of the fjord. After a while, two Mahan soldiers holding weapons emerged. The two of them were patrolling this section of the coast with the orders of the peak. Obviously, both of them were very relaxed, and it was no wonder that they had never seen a Liang soldier for dozens of days since they patrolled here.

The two of them walked while chatting, and one of them suddenly said, "Brother, I'm anxious to pee. You're here to wait first, I'll come here after I'm done." After that, he quickly walked to the coast, stood on the cliff two or three high, unbuttoned his belt and urinated. While peeing, he watched the scenery of the fjord.

His gaze suddenly swept across a floating weed, but he didn't care. It was very common for the branches, weeds, birds' nests that rushed from the river to the fjord. When he tied his belt, he always felt something was wrong.

While he was muttering in his heart how he felt this strange feeling, his companion urged him to get up and said, "Why do you urinate like shit? It's so ink-like. It won't take so long to shit, unless you urinate. Come quickly, let's change posts and go to eat, otherwise you will have to eat cold rice and leftover soup again today!"

This urge broke his thoughts. He immediately followed him. In fact, the reason why he had a strange feeling was that the inconspicuous weeds floating on the water was moving in one direction. This was not surprising on the river, but it was on the sea of ​​the fjord.

In the Bumicheng Government Office, Zhang Liao and Xu Rong were playing black and white pieces on the chessboard. Half an hour ago, the report of the attack of the Liang army's transportation team reached him. Not only was he not shocked, but he was glad that Su Shi Duli finally took the bait. He was sure that the eight car bombs would be sent to Su Shi Duli's real lair. But then he became uneasy again, that was, he didn't know if he could keep an eye on the Mahan army's fleet. Although he arranged a ranger, a secret whistle, a Viking fleet, and a semi-submersible ship at the points where the Mahan army might have evacuated. But this was still unsure.

Therefore, Zhang Liao looked very calm on the surface, but in fact he was still in a state of mind.
