The operator immediately inflated the launch canister, and then waited for Lin Fei's launch order, and gradually, the two warships approached to a distance of twenty kilometers, and Lin Fei ordered loudly: "Rocket launch!" ”

Tsiolkovsky gently pressed the launch button, the cut-off valve of the high-pressure air flow opened, and with a "bang", a rocket was rushed out of the launch canister by the air flow and shot into the sky, at the same time, Tsiolkovsky pressed the stopwatch, according to the design program, after five seconds of cold launch, the rocket engine will ignite, and the rocket will then accelerate and shoot at the target.

Five seconds came quickly, but behind the tail of the rocket, there was no flames sprayed out, and the initial kinetic energy of the rocket was exhausted, and the rocket fell like a stone into the sea.

Tsiolkovsky was so surprised that his face was bloodless, and if the rocket did not ignite again, it would not be able to hit the target, not to mention that it could not hit the target, and it could even fall directly into the sea.

The rocket still did not ignite, and fell straight into the sea, splashing a small splash on the sea, Lin Fei had been waiting to see the tail flame when the rocket was ignited, but he didn't see anything, he didn't know that the rocket was not ignited, and thought that the rocket was not launched, so he hurriedly contacted Tsiolkovsky: "Why didn't the rocket fire?" ”

Tsiolkovsky reluctantly replied: "We fired the rocket, but the rocket that was fired did not ignite, and I don't know what happened." ”

Lin Fei frowned, but he was not overly surprised, rockets, a brand-new high-tech equipment, would not succeed without experiencing a series of failures.

Lin Fei then said, "Go ahead and fire the second rocket." ”

"Obey Your Majesty." Tsiolkovsky's subordinates fired another rocket, but this rocket still did not ignite smoothly, and fell into the sea again, touching the fuse when it hit the sea, and the rocket exploded at the moment of falling into the sea, splashing a large column of water.

Tsiolkovsky was so angry that he ordered his men to fire a third rocket, but this rocket was a big surprise.

This rocket was ignited at the moment when the launch canister was ejected, at this time the rocket was over the hull, and the high-temperature tail flame instantly ignited the deck near the launch canister, and the high-pressure gas cylinders arranged behind the launch canister were scorched by the tail flame, and the gas inside expanded sharply, suddenly exploded, and the entire high-pressure gas cylinder was blown up!

Debris flew in all directions, several operators were injured on the spot, but fortunately no one was killed, and the hot tail flame swept over the other rocket launchers, scaring everyone into a cold sweat.

Fortunately, the tail flame did not deactivate the rocket in the blast barrel, the rocket flew out at high speed, and soon ran unstable, and fell into the sea after flying out a few hundred meters.

Lin Fei saw that the early ignition of the rocket had caused damage to the X-1 ship, and hurriedly ordered: "X-1 ship, stop the test, withdraw to Da Nang, the Han Wu ship, the Chengzu ship, the Tenglong ship and the Qianlong ship, go forward to meet the enemy, the Han Wu ship and the Chengzu ship are close to the French ship head-on, and the Tenglong ship and the submarine dragon ship are detouring on both wings!" ”

The four battleships were like four dragons, killing two French warships, and when the French battleships saw that there were four warships on the Huaxia side, they immediately turned their course and wanted to withdraw from the battle.

Lin Fei picked up the Blue Bird Machine and ordered in a loud voice: "Hot Air Balloon, immediately indicate the direction of the two French ships for the Ghost Shark Boat and the Demon Mirage Boat." ”

The observation distance of the hot air balloon to the French ship is as high as eighty kilometers, so at this time, the French ship has nowhere to hide in front of Lin Fei, the ghost shark boat and the demon mirage boat quickly rushed to the road of the two French ships, lurking and waiting, the underwater speed of the demon beast-class submarine is only ten knots, and it is impossible to catch up with the enemy ship in the naval battle, so it can only use the ambush method of fighting.

How could the French ship know that the two Demon Beast-class submarines were already in ambush in front of them, swaggering into the ambush circle, and the Ghost Shark Boat and the Demon Mirage Boat unknowingly launched torpedoes, sinking the two French ships.

At the end of the battle, Lin Fei ordered the ghost shark boat and the mirage boat to go to Cam Ranh Bay Military Port to intercept and kill the enemy ship, and he himself led the battleship back to Da Nang.

Although Lin Fei won a big victory, he was not happy at all, because the rockets it had carefully prepared could not ignite at all under cold launch conditions!

Lin Fei hurriedly asked Tsiolkovsky: "Why can't you light the fire?" ”

Tsiolkovsky looked embarrassed, "I don't know why, now the cause is being investigated." ”

"How many times did the failure to ignite occur during the test at the Yanhuang City base?"

"There were several occurrences, and in general, the time when ignition could not be ignited accounted for fifty percent of the total number of launches."

Lin Fei's heart trembled, if the launch success rate was only 50 percent, how could this battle be fought? Could it be that the technical difficulties of cold launch are difficult to overcome?

Lin Fei thought for a while and said, "Then give up the cold launch technology, ignite directly on the battleship, and use the hot launch technology." ”

Tsiolkovsky said gloomily: "But with thermal launch technology, the high-temperature tail flame will cause great damage to the hull. ”

"This ......," Lin Fei pondered for a moment, "I'll find a way to overcome this." ”

Tsiolkovsky nodded, "Your Majesty, if you don't have anything else to do, I'll go back first." ”

Lin Fei agreed, and immediately began to prepare for the hot launch technology, when the rocket is launched, it will emit a large amount of high-temperature gas, so it is necessary to arrange high-temperature resistant materials at the launch site of the rocket, and now in his hands, the best high-temperature resistant material is ceramics, so Lin Fei decided to arrange ceramics at the launch site of the rocket to cope with the high-temperature tail flame.

Lin Fei handed over the technical ideas to the National Design Institute, and they completed the specific design and experiments.

Although Lin Fei sank two French cruisers, he did not announce the news to the outside world, and for this naval battle, Lin Fei did not say a word about the sinking of enemy ships by sending submarines, only saying that there was a confrontation between Huaxia and France in the waters near Da Nang, and the French suffered a big dumb loss.

Lin Fei expected that the French would not dare to start a big war, so he ordered the Tenglong and Qianlong ships to lead the first division of the First Group Army to the two provinces of Guang'an and Ninghai, and in accordance with the "Sino-Vietnamese Reconciliation Treaty", they received these two provinces, which were on the seashore and very convenient to enter from the sea.

Lin Fei had just sent out his troops, and on January 10, news came out from Hue that Princess Nguyen Phuc Bao Jiao had promulgated the "Edict on the Establishment of the Country", in which she declared that the "Sino-Vietnamese Reconciliation Treaty" was an unequal treaty imposed by the Chinese Empire on the Vietnamese Empire, and the Vietnamese Empire did not recognize it, and called on all the Vietnamese people in Quang An and Ninh Hai provinces to defend their land to the death, and called on the people of Da Nang to drive the Chinese out of Vietnam.

When Zhang Jiancheng heard the news, he found Lin Fei and said angrily: "Your Majesty, this little slut Ruan Fu Baojiao really tore up the treaty, you can give an order quickly, I am willing to lead the troops to take Hue City directly, and arrest Ruan Fu Baojiao for you, and we will tie her to the flagpole when the time comes...... Hey hey ......"

Lin Fei ignored his obscenity and waved his hand gently, "No, the current Hue City must be heavily guarded, and it is difficult for our small force to fight down." ”

"So what do we do? Watching that little slut go against the sun? ”

"Of course not, for such a little slut, I will definitely punish him well, you go and bring Ruan Phuc Zhao to me."

Zhang Jiancheng agreed, turned around and left, and quickly brought Ruan Fuzhao to Lin Fei, these days Lin Fei has treated Ruan Fuzhao with courtesy, and when he saw Ruan Fuzhao today, he greeted him even more affectionately, but Ruan Fuzhao sneered and ignored Lin Fei.

Lin Fei was not angry, and said with a smile: "Your Majesty the Emperor, you have been with me for so long, it's time to go back, I'll let you go back now, do you think it's okay?" ”

"What are you talking about, you're going to let me go back?" Ruan Phuc Zhao was so surprised that he took three steps back.

"That's right, I'm just going to let you go." Lin Fei replied.

Ruan Fuzhao frowned, "You must have a conspiracy, Lin Fei, you can say it happily, what do you want to do?" ”

Lin Fei sighed lightly, "I arrested you originally to use you to threaten Vietnam and force you to sign a surrender agreement, but I didn't expect you to get a Princess Nguyen Phuc Bao Jiao and continue to fight against me." ”

"Imperial sister?" Ruan Fuzhao's eyes lit up instantly, "The imperial sister is very powerful, if she is a man, the throne must be hers, with her, Lin Fei, you will definitely lose miserably." "Lin Fei completely blocked the news from Nguyen Phuc Zhao and the Vietnamese minister, so they were completely ignorant of the Sino-Vietnamese Reconciliation Treaty.

Lin Fei laughed secretly in his heart when he heard Ruan Fuzhao's words, don't you know that your "very powerful" imperial sister was caught by me twice, once I took off her pants and spanked, and once I took off my corset to see her beautiful breasts, hehe, now she is starting to fight against me again, how to play with her again?

Lin Fei smirked a few times, and then said, "Okay, let's not talk more, you go and prepare, and I'll let you go." ”

Ruan Fuzhao was overjoyed and said goodbye and left, Lin Fei looked at Ruan Fuzhao's back, and thought to himself, my trick of borrowing a knife to kill people should work, Ruan Fuzhao will return to Hue City, he will inevitably find an excuse to kill Ruan Fubaojiao, Ruan Fubaojiao doesn't want to die, so he can only defect to me.

The corners of Lin Fei's mouth showed a wicked smile, what he was thinking was not to wait for Ruan Fu Baojiao to come and play with her, but that after Ruan Fu Baojiao came to him, he could support Ruan Fu Baojiao to be the emperor of Vietnam, and then he could completely turn Vietnam into his puppet state, and the cost of establishing a puppet state was much lower than directly encroaching on the entire country.

Lin Fei issued an order to the troops on the expedition to Guang'an Anhai, after arriving in Vietnam, pay attention to Huairou assimilation, grace and power, for the Vietnamese who are close to us, we can win over, and for those who do not obey, kill them directly.
