The situation in Boliwa City was very similar to that of Sun Martin City at the beginning.

In order to convey Zhu Jingyuan's notice, the Ming army's anti-bandit force also sent a major general-level overseer over.

The overseer is also from the clan, named Zhu Xueyan, from the line of Zhu Yuanzhang's third son, Zhu Li, the king of Jin, and the same generation as Zhu Jingyuan.

On the side of Xintianfu, in fact, not only the overseers are all clans and relatives, but the proportion of clans in the management and officers of the Huangzhuang army is also much higher than that of other places.

Because this is the new heavenly mansion, it is the back garden of the royal family.

After the reform of the vassal state began, in other places, the vassal states set up political envoys to manage the immigrants and descendants of the Ming Dynasty.

On the side of Xintianfu, the vassal state set up Huangzhuang to manage the immigrants and descendants of the Ming Dynasty.

At present, there is no political envoy in the entire South Yinzhou, as well as east of the Honey River in the North Yinzhou and south of the Great Lakes.

Zhu Xueyan took a few retinues and rode through the battlefield in the valley, all the way into the city of Boliva, that is, Medellín.

Zhu Xueyan was politely invited into the reception room by Bo Liwa, and conveyed Zhu Jingyuan's surrender conditions like Zhu Jianxuan.

Boliwa also suffered a loss three years ago, and he is more clever than Sun Martin.

It soon became clear that the Ming officer had once again used a strange negotiating logic.

Bo Liwa was more direct than Sun Martin, and asked Zhu Xueyan directly:

"According to my understanding, I personally left as a civilian, and my other companions were going to work as laborers, this is the ultimatum given by Da Ming this time.

"My choice is to accept or not to accept, if I make any other requests to the general now, Da Ming will not respond, right?"

Zhu Jingyuan didn't answer this kind of question, but just asked his own question casually:

"So what's your answer?"

Boliwa gritted his teeth, but still managed to control his emotions:

"I hope to be able to convey a most basic request to His Royal Highness Prince Daishi......

"My partners and I should at least be able to become free people directly, and leave freely without any restrictions.

"If His Highness can accept it, we can surrender in general."

Zhu Xueyan seemed to be a little puzzled and asked rhetorically:

"Why do you think you are qualified to make a request to Your Highness?

"If it weren't for your strange thinking, you would have taken your companions to live a stable and free life in southeastern Brazil three years ago, as a nobleman.

"Why do you still have such unrealistic ideas?

"All you can do now is accept or refuse, so do you want to accept His Highness's conditions or not?"

According to Zhu Xueyan's understanding of Boliwa, saying this will not make Boliwa succumb, but will likely anger him.

Angry.

Boliwa is only twenty-five years old now, and he has already achieved great results, so he is a little young and vigorous.

Even if he is almost exhausted, he is still quite proud and conceited.

Now that I am questioned by Zhu Xueyan like this, of course I feel very aggrieved, and I am extremely aggrieved:

"I ...... My answer is...... Refuse!

"For this condition, I will definitely refuse, and we will fight with you Daming until the last moment.

"But I also want to issue an ultimatum to you Daming for the kingdom of Boliva!

"My partners and I want to have an island of more than 1,000 square kilometers in the Caribbean.

"I want to become the lord of this island, with the title of baron of the Shang Kingdom, and the Ming Dynasty must not interfere in the management of the island.

"If your superiors, or your Royal Highnesses, ask you to come and contact us again, go directly to see what I just proposed.

"If you can't meet our requirements, you don't have to talk to us anymore."

Of course, these words are his own inner thoughts, and they are the best conditions for him to dare to imagine at present.

But he also knew that these conditions were almost impossible to meet.

To say it directly now is a decision to break the kettle.

If you can't get this condition, then continue to fight to the end and die directly on the battlefield.

There will be no more compromises in the future.

It's just that, according to Boliwa's understanding, no matter what he says, as long as he doesn't fully accept those conditions, these words will not be sent to the top of the Ming Dynasty.

Therefore, these cruel words are more for themselves, as well as those subordinates and friends around them.

As a result, after Zhu Xueyan heard this, he couldn't help but smile on his face:

"Very good, very energetic, I will convey your request in full to His Royal Highness Prince Daishi."

Boliwa was stunned:

"Are you really going to relay these words to the Great Food King? Instead of directly telling the Big Food King that I didn't accept the conditions? ”

Zhu Xueyan said with a smile:

"Of course not, this is your ultimatum after all, I can't hide the news......"

Boliwa broke down a bit:

"So what did you do three years ago? Why don't we convey our conditions to your higher-ups! ”

Zhu Xueyan said as a matter of course:

"This is different, you want to negotiate with us, and you issue an ultimatum to Daming, this is a completely different thing.

"We are not authorized to negotiate with you, but your ultimatum is still to be conveyed.

"Just as I conveyed to you the notice of our Highness......

"But whether Your Highness will respond, whether you will feel that you are beyond your own strength, that is another matter."

Zhu Xueyan was talking here, and Boliwa was emotionally broken over there.

At this time, Boliva's predecessor and important staff officer, Miranda, who is fifty-eight years old this year, suddenly said very seriously:

"We, the Kingdom of Boliwa, want to change the content of the ultimatum.

"We don't ask for independent special fiefdoms, we only require our main core personnel to be able to go to Dongyi to live a normal life as free people.

"As long as Da Ming can meet this requirement, we can surrender directly......"

Zhu Xueyan glanced at Miranda, and then looked at Boliva:

"Is this ultimatum also changing? Who are you calling the shots here? ”

Boliwa subconsciously wanted to stick to his point of view.

Miranda shouted directly to Boliva:

"Simon, don't be impulsive, your request can't be met, I'm talking about the only possible condition."

Boliva gritted his teeth again, but finally accepted Miranda's suggestion and said the same thing himself.

Zhu Xueyan was a little worried, and didn't seem to be happy to say:

"Okay, I'll go back and relay your ultimatum, but there may not be a response."

Zhu Xueyan drove away with the guards, and Boliwa began to discuss with Miranda and the rest of his companions.

"I can tell that the other side doesn't want to talk to us."

"This negotiation ...... It should be said that it is a notice, and it should be requested by His Royal Highness Prince Daishi. ”

"Yes, otherwise they wouldn't have come."

"So the Great Eclipse will accept our terms?"

"Our conditions are really low.

"It's just a free life."

After listening for a while, Boliwa stood up and said in a loud voice:

"Don't worry too much, Medellín is located in a canyon, hot and rainy all year round, and Daming's heavy weapons can't get in at all.

"No matter how great the strength of the Ming is, it can only fight a low-level war with us here, and can only rely on light infantry to fight.

"Our elite troops, in this case, are not far behind the Ming troops.

"This is also the key reason why Daming issued us conditions again.

"Whether Da Ming agrees or not, we must be ready to fight.

"I have a deeper understanding of Daming's culture and know where our way out is.

"As long as the Ming army is unable to break through the core area under our control for a long time, the Ming court will raise the price.

"As long as we continue to fight, we still have hope, persistence is victory!"

Boliwa's encouragement made the officials, generals, and companions around him cheer up again and prepare for battle with anticipation.

Zhu Jingyuan also soon received a report from the two bandit suppression corps in Xintianfu.

Martin Sun accepted the conditions, which Boliwa refused.

"Boliwa issued an ultimatum to Daming, if we can't meet it, don't talk to him anymore.

"Their condition is that he and his subordinates can leave completely freely."

Zhu Jingyuan hesitated a little after reading it.

Martin Sun accepted the conditions directly, which is a relatively reasonable result.

The situation in Sun Martin's kingdom was even worse, although it was surrounded by mountains, rainforests, swamps, and highlands.

The high ground is actually quite flat, and it is not particularly difficult to attack from the high ground.

As long as the Ming Dynasty mobilizes enough chariots and planes to go up, and organizes a large enough charge, it can be overpowered.

So Martin Sun has no choice.

What made Zhu Jingyuan hesitate was Polya's so-called ultimatum.

It's just that the main core members leave freely, which is actually not a high condition.

And the local area is very close to Panama, and the ordinary soldiers and population below can be sent directly to dig the canal.

But what do you mean by this ultimatum?

A rebel leader who has become a turtle in an urn directly rejects his own conditions, and then issues an ultimatum to Daming?

Can this get used to you?

The understanding of the Ming officers was completely correct, and the conditions that Zhu Jingyuan gave to these people were all ultimatums, not invitations to negotiate.

Zhu Jingyuan was not ready to negotiate with them.

How could it be possible to accept their ultimatum-style negotiations?

In particular, Zhu Jingyuan is also ready to test new tactics, especially since Martin Sun's side has surrendered.

If Boliwa surrenders again, he will have to go to North Yinzhou for testing.

Zhu Jingyuan then responded directly to Zhu Xueyan:

"Ignore the ultimatum and start organizing a continuous strategic bombing tactical test."

After the battle order was issued, Zhu Jingyuan and the troops responsible for carrying out the mission began to consider how to carry out the battle plan.

Medellín is located in a tributary valley in the northern Andes Mountains.

It is surrounded by tropical rainforests with annual precipitation of more than 2,000 millimeters and even 3,000 millimeters.

It rains two-thirds of the days of the year.

As Boliwa said, this is a hot and humid mountainous terrain, and it is difficult to transport heavy weapons into it.

That's why he has shrunk his defense until now, and he still has some confidence in negotiation.

Even if Da Ming had a plane that could be called a foul at this time, he still needed to plan his attack relatively carefully.

In the South Yinzhou area, outside the core area of Xintianfu, transportation mainly relies on sea transportation.

Therefore, the starting point of the attack is best in a coastal city, or a navigable inland river city.

Medellin is only 200 kilometers away from the coastline of the Ming Ocean, and it seems that the combat radius of ordinary bombers can cover it.

But this route is all rainforest, and it is all hot and rainy all year round.

Entering Medellín from the east, planes need to cross the Andes Mountains from east to west, which are exceptionally rugged.

Navigating through mountains and deep valleys and dense forests in torrential rains is a huge test of current flying skills.

It is very dangerous if there is a sudden heavy rainstorm during the round-trip trip.

Although it is possible to temporarily climb above the clouds, the height of the clouds is not completely fixed, and the fighter at this time is not the kind of aircraft that will climb 10,000 meters casually in later generations, and it is inherently dangerous to pass through the clouds in a thunderstorm.

Comparatively speaking, the terrain in the east and north of Medellín is relatively gentle.

Less than 100 kilometers east of Medellín is a flat valley area.

Two hundred kilometers to the east is a savannah climate with 1,500 millimetres of annual precipitation.

Within a range of 200 kilometers, the Ming Dynasty's single-engine fighters and bombers were able to fully exert their combat capabilities, and they could all operate with full load or even overload.

Although it is an inland area, there is the Magdalena River, the largest river in the Colombian region, which passes through this valley, and the natural navigation conditions are very good.

The estuary has a river-sea connection port, which allows seagoing ships to dock in the harbor and turn to inland waterway ships to transport supplies upstream.

Therefore, the combat unit chose a base for small aircraft in a small town along the river, 210 kilometers northeast of Medellín.

This is just a small aircraft, and large aircraft can be farther away from the combat distance and can be placed farther away.

Four hundred and sixty kilometers north of Medellín is the Caribbean coast of Cacheng (Puerto Cartagena).

The amount of precipitation here is about 500 millimeters.

Kacheng has a relatively mature port and urban area, and it was originally the combat supply center in the north of Nanyinzhou.

Large transport ships are replenished by sea, the ammunition is of course very abundant, and the climate is suitable for the storage and maintenance of aircraft.

The twin and quadruple bombers of the Ming Dynasty could directly bomb Medellín, less than 500 kilometers away, from this starting point.

There was already a small-scale airstrip base for operations.

Daming's first strategic bombing base in Nanyinzhou was selected here.

The next task was to expand the airport as quickly as possible to transport and transfer and concentrate the aircraft.

Daming and even the world's aviation industry has just started less than four years now.

Before that, there were no such facilities as airports in the world.

In the war against bandits in Nanyinzhou, in order to test Zhu Jingyuan's combat plan, some improvised airfields were built one after another.

The time for construction was limited, and it was too late to build a high-standard airport.

The take-off and landing capabilities of propeller aircraft in this era are also relatively good.

Far less delicate than the high-precision jets of later generations.

Small planes can take off and land on dirt roads, gravel roads, and grass.

As long as the land is bulldozed, it is considered to run, and it is paved with cement or asphalt, which can be regarded as a high-grade runway.

Now it's time to extend and scale these up.

At the same time, shelters for rain and maintenance were built, and existing buildings were converted into ammunition warehouses.

Planes from other regions, planes around Xintianfu were all transferred, and even planes were transported from Daming territory.

These areas already belong to the northern hemisphere, and it is already summer in May of the Ming calendar.

However, the following June coincides with the time of less rain in the summer.

Zhu Jingyuan and his combat units set a one-month preparation time, and a month later they officially began to experiment with primary strategic bombing.

During this month, the ground forces of the Ming Dynasty basically stopped the offensive and turned into a state of siege.
