Faced with this unexpected situation, not only Gao Ming frowned a little, but the two boat owners and bosses who often walked the Red River channel were also quite surprised.

After thinking for a while, Boss Hu shook his head slightly, and said: "This is really strange, even if the people of Annam are so powerful that they have fine work in Qinzhou, and they are very sure that we are here to embarrass them when we leave the port this time, but even so, they don't have time to notify the Shenglong side to arrange these 'river chun'!" ”

"That's right, the old has a point." Boss Li also frowned and said, "Even if the Annan people are really unexpectedly smart this time. But from Qinzhou to Thang Long, and then from Thang Long to the mouth of the Red River...... How could this news spread so quickly? Can the efficiency of the Thang Long Annam people be so high? ”

"You all have a point." Gao Jue also frowned, and said: "Qinzhou is the Qinzhou of my Ming Dynasty, even if the Annan people have a fine work in Qinzhou, it is impossible to have a six-hundred-mile rush or an eight-hundred-mile rush, if we leave the port, the other party will send the news back to Annan again, and the land route will not be so fast." And the sea route ...... Qinzhou is Jinghua's private port, which ship leaves the port, we don't know? Recently, all the ships that have gone to sea in Qinzhou Port are in our fleet, how can it be possible to inform the Thang Long side? ”

He vetoed the possibility of Annan Hosaku transmitting information, but he couldn't figure out how the news was leaked for a while. At this time, Boss Li interjected and said, "Perhaps, these 'river chun' actually have nothing to do with us?" Maybe...... Maybe it's used against pirates? It doesn't seem that far from a pirate's lair, does it? ”

"Not far from the pirate's lair is the mouth of the Ganghe River, not the mouth of the Red River." Boss Hu shook his head and said, "There is still some distance between the mouth of the Red River and the mouth of the Yan River. ”

"Besides...... Boss Hu paused and added: "Pirates plundering along the coast is a common thing, and the area around the mouth of the Red River is not without being harassed by pirates, but I haven't heard of pirates daring to go up the Red River and rush all the way to Thang Long?" That's too arrogant, Thang Long also has Mo's regular water army in normal times! Could it be that those pirates still want to fight head-on and pick Mo's naval army? This is also outrageous. ”

Gao Jue looked at those river tsubaki, pondered for a moment, shook his head resolutely, and said, "No, these 'river tsubaki' are not used to deal with pirates!" You see......"

He stretched out his hand and pointed, and said, "Back then, the tall old man was the commander of the river, and I fought against the Japanese invaders, so I still know a little about the 'river chun'. In front of me, these 'river tsubaki' are only in the middle of the river meandering line, and the distance between the two rows of 'river tsubaki' in front and back is ten zhang, and the arrangement is very sparse, so the boat is definitely not stoppable, and the sampan can even pass between the two 'river tsubaki' at will. Larger boats can also slowly bypass the 'river tsubak', or avoid the central channel and go to both sides, and even the two of you boats may go around it. Only real sea ships, such as these armed transport ships in Jinghua, can really not get by. ”

When the two bosses heard this, they hurriedly went to see it, and after another look, it was so. Because the "river tsubaki" is arranged in an S-shape, when the big ship goes around the first row of "river tsubaki", because the hull is long, the second row of "river tsubaki" will not be avoided anyway. Moreover, the river is not as deep as the sea, the water level is deep in the center and shallow on both sides, and it is the dry season at the moment, so if the big ships do not take the central channel and go around both sides, then in some sections of the river, there may be a danger of running aground.

Therefore, the arrangement of this "river chun", as Gao Jue said, is to stop the big boats but not the small boats. The ships of those pirates are generally smaller, because they are small and flexible, and they can escape if they can't beat them. Therefore, this "river tsubaki" is obviously not used to deal with pirates.

So whose ship is bigger? Thinking about it now, it seems that these armed transport ships in Jinghua are big ships, although compared to the big treasure ships when the Ming Dynasty was the most majestic, this is also a small point, but at least for now, it can still be called a big ship.

"Looks like it's really going to be against us." Boss Li's tone was a little depressed, and he said: "Since these 'river chun' can only deal with big boats, they must be aimed at us, but I still can't figure it out, how did they guess that we would come to Shenglong, and use 'river chun' to block the mouth of the Red River?" ”

As he spoke, he sighed and added: "Anyway, this 'river chun' is arranged like this, and it does not affect the navigation of the boats very much, that is to say, while stopping the gunboats of Jinghua, it does not have much impact on the people of Annamite themselves. ”

"The impact is still there." Boss Hu is experienced and observant, pointed to a river chun, and said: "Gao Tuanzuo, Lao Li, you see, this 'river chun' is equivalent to a simple sluice, when it flows through the 'river chun', the amount of water will decrease, and the amount of water flowing between and next to the 'river chun' will increase accordingly, and the water flow will speed up because of this, and for small boats, the resistance will also increase greatly." ”

When he said this, he reminded himself again, and added: "Also, the flow of water flowing through the 'river tsubaki' and the flow between and even next to the 'river tsubaki' have different velocities, which can easily form whirlpools and cause further danger to the passage of small boats...... Look, there's a whirlpool over there! ”

Gao Jue and Boss Li looked in the direction of his finger, and sure enough, as he said, the water flow here has become very disordered because of the relationship between the river and the tsubaki, and a whirlpool has been formed.

Boss Li touched his beard and said, "Then it seems that the actions of the Annan people are really killing 1,000 enemies and losing 800 themselves." Let's not forget, in addition to these things affecting their boats, their own sailors are now also heading south to fight against the Li clan, and when they return, won't they have to face these obstacles? The people of Annam are really not afraid of trouble! ”

"Wait!" Gao Jue suddenly remembered what Boss Hu said before, and said: "Boss Hu said before that Li's side is now hooking up with the Franc man, not only to buy artillery from the Franc man, but also to buy two warships, planning to use this to fight against the Mohs Navy?" You say, did the Annanites set up these river rafts to block the two Franco-warships? ”

Boss Hu and Boss Li were reminded by Gao Jue, and at the same time slapped their thighs and said in unison: "That's right!" Quite possibly! ”

Especially Boss Hu, he also added: "No, it's not possible, it's inevitable!" Only in this way can Mohs be explained! With these river tsubakes, although they may not be able to stop the two Francophone warships, they can at least delay them for some time. ”

Gao Jue breathed a sigh of relief and put his mind at ease: "In this case, let's take a little effort to pull out these river chuns, I have experience in this area, these river chuns ...... In a day at most, we can clean it up. ”

In one day, even if the Thang Long side learned the news and made preparations, the preparations were limited, and they could basically achieve the effect of a sneak attack.

In particular, this place may not be an area that the Mo Dynasty government cares about, and there are only some poor fishermen around, and these fishermen do not seem to have any hostility towards their fleet, which is not a "Li Reverse Water Division" at first glance, and may not report to the government at all.

In this case, Thang Long may not be able to give much early warning.

Gao Jue's method of dealing with these river tsubaki is a little time-consuming, but it is not laborious. He just ordered someone to tie the prepared cable at the anchor position of the bow of the ship, and sent a small boat to tie the river chun at the other end, and then ordered the whole ship to open its sails, and the huge kinetic energy pulled out the wooden stakes that had rammed into the bottom of the river at once.

This is because the sand at the bottom of the river is soft, and the roots of the "river tsubaki" are basically not very strong.

By the way, these two chapters mention the transaction between Li Chao and Franc Ji, the purchase of ships, etc., which is to pave the way for the follow-up plot, and I can't accept the number of words in the water - besides, this is originally a plot story, and I haven't explained any reason.
