Lang Zhong and the confessors were officials who served and admonished Liu He, but in terms of affiliation, they were actually Lang Zhong's subordinates.

In other words, Lang Zhongling is the direct official of Lang Zhong and the confessor.

Lang Zhong and the confessors served the princes and kings, but they were selected and appointed by Lang Zhong Ling, and Lang Zhong Ling of Rank Qianshi was appointed by the imperial court.

Under this interlocking means, the princes and kings became loners in the true sense.

The prime minister is in charge of the hundred officials and the people, the lieutenant is in charge of the prison and the soldiers, and the lieutenant Lang is in charge of the palace garrison.

The three form a stable iron triangle, locking the princes and kings firmly in the middle, unable to move, unable to move an inch.

And among these three people, the closest to the princes and kings is Lang Zhongling.

If you want to break through the barrier, you must first take down Lang Zhongling.

The Lang Zhong Ling that Yu Wuwu and Liu He said is the Lang Zhong Ling Gong Sui of Changyi State.

Gong Sui's age is on par with the royal style, and they are both respected ministers of Changyi State, and they often fight for a red face in order to share their virtue and prestige in private banquets.

Although he wants to be old, this Gong Sui and Wang's personalities are diametrically opposed.

Wang Shi is a Confucian scholar who is poor and stubborn.

Gong Sui is a follower who has been applied by the world and a reformer who dares to be the first.

It's just that both of them were born at the wrong time.

Especially Gong Sui, when he was in his prime, he came to the palace of Changyi and became the commander of Lang Zhongling. seems to be a high authority, but it also cuts off the way for him to display his more ambitious talents.

What's more, Gong Sui met the king of Changyi, who rebelled against Meng Lang, which made him feel physically and mentally exhausted and depressed.

Choosing Lang Zhong and the confessor for the king of Changyi was almost Gong Sui's last effort.

However, Liu He's arrival in this world has changed the trajectory of many people's lives, including Gong Sui, an old man in his last years.

After a short period of contact, Gong Sui discovered the advantages that Liu He suddenly burst out, and Liu He also used his talents to successfully gain the trust and recognition of the other party.

So, Liu He conquered the most difficult link in the Iron Triangle and walked to the front of the stage smoothly.

If Gong Sui had not been "subdued", then Liu He would not have done anything in the past two years.

Of course, Gong Sui, a dead tree that was about to die, was also reborn, and his motivation was a hundred times stronger than those Langzhong.

Now, Yu Wuwu mentioned Gong Sui, and couldn't help but remind Liu He of the scene of saying goodbye to Gong Sui in Changyi Hall seven or eight months ago.

"Gong Qing, this trip is a long way, difficult and dangerous, you are already long-lived, otherwise it would be good for the widow to send Dai Zong and them."

"Taigong Wang's seventy and Xiang Jichang, the lower official is only sixty and two this year, and he can also share his worries for His Royal Highness, not to mention, I traveled to Lingnan when I was young, and now I happen to revisit my hometown."

"Okay, when Gong Qing returns, the widow will personally pour wine for you in Changyi Palace."

"His Royal Highness has the grace of knowing the old minister, and he can only repay it if he does not disgrace his mission."

The scene seemed unremarkable, but there was a hint of tragedy.

Because, the Lingnan that Gong Sui is going to is not the rich appearance of the later generations.

It is said that tigers and leopards are rampant there, and there are herds of apes, and during the day they dare to attack passers-by in groups.

In addition to these fierce beasts, the mountains and forests are also inhabited by the Yue and Yi people with hair and tattoos, and they are even more eyeing the merchants.

Therefore, Gong Sui's journey to the south is destined to be difficult.

Gong Sui, who is at least an official with a rank higher than Qianshi, wants the help of officials along the road, which is much easier than Langzhong and the confidant of low rank.

In addition, Lang Zhongling's affairs are not busy, which makes Gong Sui's long trip possible.

Liu He and Gong Sui made such a big move and went deep into the dangerous Lingnan, naturally not to let the old man revisit his hometown when he was young.

Rather, it is to find something, to be more accurate, a plant that can change the lives of the people of the Han Dynasty.

The news released from the palace of Changyi was that Wang He of Changyi was suffering from a serious head wind disease and needed a flower called Jibei as a medicine guide, this plant was "like a cocoon, and the silk in the cocoon was like a fine thread", and only people in Lingnan planted it.

In the palace of Changyi, Liu He preferred to refer to Jibei as cotton, a plant that would replace hemp in the future.

In order to make the story of "Lao Chen's life for the savior go deep into the barren" to be more realistic, Dai Zong and other confessors also released words in the Changyi Kingdom at the same time, claiming that the palace was willing to buy Jibei from the people for 100,000 yuan.

As a result, Gong Sui's southward journey was even more impeccable.

At this moment, when Liu He made sure that Gong Sui was safe and sound, he then asked: "Did Lang Zhongling mention the matter of cotton in his letter?" ”

"As I mentioned, Lang Zhongling went all the way south, and when he was about to enter Nanhai County, he finally saw cotton in a native vegetable garden."

"Did you bring back the seeds?"

"Not only did they bring back the seeds, but they also brought back the cloth woven from cotton by the local natives."

"And Lang Zhongling also brought it back with the natives, the man is good at growing cotton, and the woman is good at weaving cloth with cotton spinning."

Jiang is really old and spicy, and Gong Sui has already thought of this layer.

Hearing this, Liu He suddenly had a little question: "How can this native be willing to leave his hometown for thousands of miles?" ”

"Lang Zhongling didn't write it in the letter, Zuo is just inconvenient to make a living in Lingnan, the subordinates heard that insects and snakes are rampant there, it's a hell on earth, what can I be nostalgic for?"

Yu Wuwu said it as a matter of course, which made Liu He, who had seen the prosperous scene of Lingnan in the future, couldn't help but smile secretly.

No matter why the native came, hearing this, Liu He, who had been busy for most of the day and was already a little tired, suddenly became excited again.

The introduction of cotton into China is divided into two routes, one from Central Asia to the Western Regions; One from Central Asia to Kushan to Jiaozhi, and then to Lingnan.

According to the original historical trend, it would take several hundred years for this cotton to reach the Jianghuai Plain.

But Liu He knew that there were already people planting cotton in Dahan at this time, but there were still thousands of miles away from the Jianghuai Plain.

With the broken carriage driven by Yu Wuwu, it will take eight or nine months to complete these thousands of miles.

But cotton has taken nearly a thousand years to break the barrier of this distance.

Being able to make the people of the Central Plains wear clothes made of cotton cloth a thousand years in advance, how could this not make Liu He excited?

What's more, this cotton cloth can not only make people warmer, but also have other uses.

Liu He, who was a little overly proud, asked Yu Wuwu beside him as if showing off: "Yu Langzhong, do you know why the widow has to go all the way to find this cotton?" ”

"Your Highness has said that cotton is easier to grow and harvest, and it can be spun and weaved, which is lighter and more comfortable than linen, and cheaper than silk."

"What else?"

"You can dress the people warmly."

"What else?"

This time, Yu Wuwu couldn't answer. The answer just now was also told to him by Liu He.

Looking at Liu He's smug expression, Yu Wuwu knew that His Royal Highness must still have a deep meaning.

"The subordinates don't know, and I ask Your Highness to give me advice."

"Don't worry, you have to remember that no matter how small it is, it can cause a huge change."

"And this little cotton can change the general trend of the world."

Yu Wuwu often "taught" Liu He in the daily code of conduct, but when it came to "pragmatic learning", he was still very self-aware, and he did not accuse His Highness of getting carried away at the moment The expression is not in line with the golden mean, but waited for the other party to continue without saying a word.
