The train experiment was a great success, and Li Shimin saw the immense value of the train.
Trains are much faster than steam locomotives.
Ling Yi estimated that the top speed could reach approximately 300 kilometers per hour.
As for the issue of train turning, sorry, there was absolutely no design for it.
After all, the railway tracks that Ling Yi has designed are all one-way lines with no intersections. Once the train starts moving, it can just go all the way along one track.
However, a problem almost occurred when parking at the finish line.
The train was just a hair's breadth away from derailing.
Looking at Li Shimin and the others who were still cheering, Ling Yi secretly wiped away non-existent cold sweat from his forehead.
The novice drivers were nearly scared to death.
It should be noted that the emperor of the Great Tang and the key officials who maintain the normal operation of the Great Tang were sitting inside the train.
If it had been just a tiny bit off, the Great Tang would probably have been finished.
In fact, Ling Yi had already conducted a test while in his Personal Space. From the highest speed to the deceleration and braking, and then to the train coming to a stop, it took nearly twenty minutes, requiring him to improve his distance by six thousand meters.
This is assuming the train is empty; if it's fully loaded with goods, the distance would be about three times longer.
Ling Yi had mentioned this to these novice drivers before.
But since it was their first time, they were so caught up in the novelty that they forgot to notice they had entered a deceleration zone marked with white cesium.
I braked a fraction of a second too late.
Overall, however, there shouldn't be any major problems.
When the cart was loaded with smelted Iron Body and returned to Chang'an City, it had only taken a few hours.
If we were to use the old transportation efficiency, it would probably take several months to transport the same block of Iron Body.
At Li Shimin's insistence, Ling Yi laid four railway tracks and four trains as required by Li Shimin.
All four railways led to border regions, and Li Shimin always prioritized Guard the border territories.
Although the Göktürks Genki and nearly wiped out due to Ling Yi's presence, Göktürks were not the only countries eyeing the Great Tang.
With these four railways, the efficiency of transporting troops and food increased by hundreds of times.
Li Shimin wanted to lay railway tracks throughout the entire Great Tang, but unfortunately, the iron reserves had been exhausted.
By the time Ling Yi finished dealing with this matter and returned to Chang'an, it was already half a month later.
It's only because Ling Yi can fly now, and he has Personal Space that gives him an advantage; otherwise, even in modern times, laying these four railway tracks so quickly wouldn't be a simple task.
As the railway tracks were laid, the Spacetime Energy within the Personal Space became increasingly concentrated.
Ling Yi estimated that a new Space-Time Anchor would be born soon, allowing him to travel to the second world. Ling Yi was very much looking forward to it.
But waiting like this isn't Ling Yi's style.
To reiterate, the Great Tang at present is not yet capable of supporting industrial development.
With problems such as education, population, powerful clans, an empty treasury, and food shortages, the Great Tang needed a stable period of development.
The food issue, in particular, is the key obstacle to all of this development.
Therefore, Ling Yi prepared to leave the Great Tang and travel to other parts of the world to search for Legend high-yield crops such as Potato, sweet potatoes, and corn.
Upon hearing that Ling Yi was going out to find high-yield grain crops, Li Shimin was both moved and reluctant to part with him.
The last bit of resentment she had towards Ling Yi vanished.
Humans fear the unknown, and even more so, powerful and uncontrollable beings; Li Shimin was no exception.
Even though he and Ling Yi now call each other brothers and seem to have a good relationship, Li Shimin, or rather the court officials, still harbors resentment towards Ling Yi.
After all, Ling Yi is both powerful and uncontrollable. If he were to lose his Ling Yi one day, what would they use to stop Ling Yi?
There's absolutely no way.
In fact, if his daughter weren't still so young, Li Shimin would have wanted to marry her off to Ling Yi in order to bind Ling Yi with familial affection.
"I am deeply grateful for everything you have done for the Great Tang, sir," Li Shimin said, Fist Dao to Ling Yi.
"Why all the fuss? Just be a good emperor, a great emperor who will be remembered for the Ancient One. Otherwise, all this work of mine will have been for nothing."
"Haha, please rest assured, sir, I will never let you down," Li Shimin said with a confident smile.
Ling Yi was just saying that; from the moment he appeared in this world, the Great Tang here had already gone astray.
As for what direction things will take in the future, Ling Yi doesn't care at all.
What he cares about is change.
Logically speaking, whether the change is positive or negative, it should allow the Personal Space to acquire the Power of Space-Time.
Building is difficult, but destroying is far too easy.
However, Ling Yi still has sound values and a bottom line.
"I'm leaving now, everyone take care!"
Ling Yi waved to the crowd, then pressed his hands down, and two streams of air shot out from the fan-shaped channels on both sides of his arms.
He slowly flew into the sky with Ling Yi in his arms.
This is the powerful thrust generated when Ling Yi absorbs the surrounding air with his Personal Space, compresses it, and then releases it into a one-way closed fan-shaped pipe.
This method is safer than the high temperature after direct compression.
Ling Yi is, after all, an ordinary person, and iron conducts heat very quickly. If he were to use heat energy as a driving force, Ling Yi would have to go through the trouble of absorbing the high temperature conducted in twice.
On the contrary, using compressed air as kinetic energy avoids these problems.
Of course, calling it troublesome is just a passive setting for Personal Space.
Ling Yi was mainly worried that starting with thermal energy would harm Li Shimin and the others below who were watching him with envy.
Ling Yi passively configured all these processes in his Personal Space, allowing them to be activated with a single thought.
It's actually quite simple.
Ling Yi even specifically designed different flight gear settings, which are the levels of thermal energy or airflow compression, and the levels of propulsion.
"Boom!"
After the silver-white armor rose to a height of 100 meters, a powerful airflow surged from beneath its feet, its speed suddenly increasing. In the blink of an eye, it Potian with a rumbling sound and disappeared.
"He must be a celestial being," Du Ruhui exclaimed.
"If only I, Old Cheng, had a suit of flying armor like that, I could take down all the surrounding small countries by Old Cheng."
Everyone rolled their eyes in unison. "Do we even need you for this job?"
Anyone wearing Ling Yi's outfit would be invincible!
"Alright, my esteemed ministers, our sir has devoted himself wholeheartedly to the cause of our Great Tang. We cannot slack off; each of us must fulfill our duties. This year, we are trying out the new imperial examination system, and we must not make any mistakes that would make our sir laugh at us."
"I will leave it at that for today. Anyone who dares to make a mistake at this time will not be spared."
"Yes, Your Majesty!"
Who would dare cause trouble now? Haven't you noticed that all the aristocratic families are behaving themselves?
With Ling Yi backing him up, Li Shimin became noticeably more reckless in his actions.
In the past two years, quite a few members of aristocratic families have died.
The methods used to threaten Li Shimin in the past are all useless now.
Resign from office? Then get out of here.
Those who delay government orders and outwardly comply while secretly disobeying them shall be executed without pardon.
Those who plot in secret will have their entire family executed if discovered.
During this period, the area around the Meridian Gate and the vegetable market was packed with people.
In the past, if Li Shimin had used such a method of killing, there would likely have been people inciting the common people to rebel.
But now that Li Shimin has the newspapers in his hands and controls the direction of public opinion, all these methods are useless.
The powerful families had considered a fight to the death, but Li Shimin had a powerful figure backing him up.
The group that Thrusting Li Shimin and Ling Yi last time remained frozen for a month, allowing people to "visit" them every day, which terrified many.
Meanwhile, on Ling Yi's side...
Without GPS navigation, Ling Yi could only fly eastward. Although his destination was South America, he would stop and search for islands along the way.
As they flew, Ling Yi veered off course.
It was originally flying east, but ended up heading straight southeast.
Half a day later, Ling Yi saw an archipelago from the air.
Ling Yi didn't know where he was, but since he had come across an island, he naturally wanted to go down and take a look.
"Banana trees, coconut trees, Banana, have I wandered into a tropical region?" Ling Yi landed on the island and immediately saw the vast expanse of tropical plants.
Ling Yi casually swept a large area of coconut and Banana trees into his Personal Space. Although these things could not be used as crops in the north, they were still fruits that were rarely seen in the Great Tang.
After looting one island, Ling Yi moved on to the next.
When Ling Yi saw the plants on the island, his eyes lit up immediately.
"Could this be a breadfruit tree?"
Ling Yi accelerated and arrived at a very thick breadfruit tree, its branches laden with fruits the size of rugby balls.
"Breadfruit tree, huh? I think it's a high-yield food crop, right? I remember it can harvest several times a year, and one tree can provide three or four hundred catties of breadfruit a year."
"If we planted a large area of these in the Great Tang Dynasty, wow!"
Of course, Ling Yi also knew that this thing had rather strict requirements for its growing environment.
It cannot be grown in most parts of the Great Tang, but it can be grown in the south of the Great Tang.
As for the remaining areas in the south that haven't been recovered by the Great Tang? They can be taken back when he returns.
It's no big deal.
When the time comes, we'll take over all those small countries in the south, and then have the locals plant breadfruit trees directly for the Great Tang.
The discovery of the breadfruit tree made Ling Yi very happy.
This is a good start.
Ling Yi roughly guessed his current location. After searching around and determining the direction, he flew north again.
Sure enough, as it was getting dark, Ling Yi came across a Great Island.
From the air, it looks like a Great Island shaped like a pea.
"Let Li Shimin come over and plant a flag later!"
It was already dark when Ling Yi landed on a hilltop and casually released a two-story building.
I stepped inside.
This was a portable "tent" that Ling Yi had prepared in advance. After all, he didn't know how long he would be wandering around outside this time, so it would be convenient to have a place to stay with him.
Unbeknownst to Ling Yi, his sudden descent from the sky and the casual creation of the two-story building were witnessed by a group of natives Hunting nearby.
The natives immediately lost their appetite for hunting. They chatted amongst themselves for a while, then approached the mountaintop cautiously with pious expressions.
When Ling Yi woke up the next morning, he pushed open the door and was stunned to see a group of primitive people kneeling on the floor in front of him.
