After Yang Dong dealt with the affairs of Xiongguan,

He immediately set off and returned to the capital,

After all, strictly speaking, his visit to Xiongguan this time was not in accordance with the rules, and he also interfered with the military power of the Yongwu Army.

Although the Yongwu Army was established by him, it is now the army of the Great Zhou after all, and even if he commands the army, he must have His Majesty's holy decree.

Yang Dong didn't have any of this, although emotionally speaking, he felt that Ji Ziyue wouldn't do anything to him.

But reason told him that the emperor was a creature that could not be inferred by common sense at all.

Therefore, in the end, for the sake of his own life, it is also because he has always firmly pursued the idea of staying until the end.

Therefore, after dealing with the affairs of Xiongguan, he immediately returned to the capital.

……

suburbs of Beijing,

In front of a tea stall,

Yang Dong, who had rushed all the way, only felt that his mouth was dry, so he simply rested here for a while.

At this moment, the words of the two footmen caught his attention.

"Have you heard, recently, near Bailu Peak, a poisonous oil suddenly appeared, poisoning many animals. I heard that wherever this thing goes, there is no grass, and if it is lit, it will emit a lot of poisonous smoke, and once people get close, they will be dizzy, have a headache and nausea. ”

"What, that's the case!?"

When the turbaned merchant heard this, his face was shocked.

He was originally a villager at the foot of Bailu Peak, and because of the compulsion of life, he took up the business of walking.

Although he made a lot of money, he also encountered many dangers. He let out a long sigh with a depressed look on his face.

"Alas, the people near Bailu Peak are really pitiful!"

"In the early years, I encountered soldiers and bandits, and many villagers died. Later, just after the soldiers and bandits passed, there was a great drought that had not been encountered in a century. It's better now, just to destroy this land? ”

"Okay, I know brother, you're from the vicinity of Bailu Peak, but don't be too upset. I heard that the imperial court has now issued a lot of decrees that benefit the country and the people, this matter is ...... Maybe the imperial court will take care of it. ”

"Can the imperial court be trusted?"

The turbaned merchant had a look of disbelief on his face.

"That's it, let's have tea! Now in this world, it's good to be able to save yourself! ”

……

Poisonous oil, and smoke will come out when ignited?

And it also came out of the mountains??

At this moment, there is only one thing in Yang Dong's mind, and that is - oil!

Master wouldn't be so lucky to find oil, right?

If there is oil, can the master be able to ......

Yang Dong scratched his ears and cheeks anxiously, but the use of this oil, in addition to knowing how to burn, is to add alkali to it and use it to make soap.

Wait, soap!?

Why did the master forget such a lucrative business?

Yang Dong's eyes lit up,

Immediately put the depression of not being able to use oil behind me.

Anyway, with oil, and with Lanxiang Academy,

As for how to use it later, there will always be someone who studies it, right?

Moreover, although Yang Dong can't, he can at least point them out the ideas and directions of research, such as...... Using simple fractionation, gasoline and diesel are made......

But how pure this is, and whether it can be done, requires a lot of experimentation.

At least in the current Yang Dong's opinion, this is not an easy task.

So

It's better to give the students of Lanxiang Academy a headache!

Thinking of this, Yang Dong was in a good mood, and after secretly writing down Bai Lufeng's name, he also left a few grains of broken silver, and directly settled the tea fees of the two merchants.

And so, after another half day or so,

On the post road, Yang Dong galloped on his horse and finally returned to the capital.

Looking at the towering city wall of the capital, Yang Dong couldn't help but feel a lot of emotion in his heart.

Although in the memory of the original owner, he grew up in the capital for as long as he can remember. However, he never left the palace at all.

Because of this, he always has a sense of strangeness when facing the capital.

Of course, today's Yang Dong is not a stranger to the capital.

Although he is not familiar with it, he still knows some about the general layout of the streets and markets.

Riding on a steed, stepping into the gates,

On both sides of the street, now it has gradually begun to come back to life,

Many small traders gradually increased, and the pedestrians and people who came and went also had a little more light in their eyes.

It seems that she suggested that you gradually open up the market, and she listened to it.

Although it can be seen that these small traders are still a little cautious,

However, Yang Dong knew that it would not be long before the capital would definitely become prosperous again!

When I arrived in the capital,

On the contrary, his heart became less anxious,

Not to mention anything else, now that the Xiongguan crisis has been lifted, I think I have done the right thing.

Allow for her...... It shouldn't be so stingy.

And...... I also happen to want to visit the capital and see if there are any good suggestions that I can give to Your Majesty.

Thinking about this,

Yang Dong decisively and gently clamped the horse's belly, turned the horse's head, and walked in the direction of Baiwufang.

Baiwufang is the largest place for merchants to circulate in the outer city of the capital.

However, in Yang Dong's view, it is obviously more appropriate to call this place a wholesale market.

Merchants who come and go, merchants who buy goods, farmers who sell goods......

All in all, even on weekdays, Baiwufang can be said to be a place with a lot of traffic and people.

Yang Dong looked at the crowd of people, his eyebrows gradually relaxed,

It seems that it is worth it to do so much by yourself.

At least the people now, although they are not living and working in peace and contentment, at least they have a hope for life.

Someone once said,

Hope is something more precious than diamonds!

And what Yang Dong saw was that the current Baiwufang was a vibrant and hopeful place.

At this moment,

A shout caught his attention.

"Selling sugar gourds, rock sugar gourds~"

This big week, there are even rock sugar gourds that are sold?

A look of surprise flashed in Yang Dong's eyes.

He immediately turned over and dismounted, tied his horse to the door of a shop, and walked quickly to find the vendor who sold rock sugar gourds.

"How do you sell this rock sugar gourd?"

"This lord, you have a good look, the big and round sugar gourd, one string of three cents, two strings of five cents......"

"Give me a ...... Five skewers! ”

Yang Dong casually took out a broken piece of silver from his arms and handed it to the vendor.

Seeing this, the peddler immediately smiled,

From the wooden stake behind him, he selected five strings of the largest and freshest sugar gourds, put them into paper bags, and handed them to Yang Dong.

"This lord, your sugar gourd."

"Alright, thank you!"

Yang Dong nodded, and was about to turn around and leave, when he suddenly saw several big men, angrily rushing towards a stall selling cooking cakes.

"Bastard, you dare to go out of the stall? I have to teach you a lesson today! ”
