Since the Turks were destroyed, the Tang Dynasty temporarily stopped its large-scale foreign war. On the one hand, the Tang Dynasty consumed a lot of financial and material resources in the battle to destroy the Turks, which took some time to rest and recuperate. On the other hand, it eliminated the most powerful enemy from abroad. There were no more powerful enemies around that could threaten the Tang Dynasty, so there was no need to fight on a large scale. As for Hou Junji's previous use of smallpox to destroy Tuyuhun, it was just a pure accident.

However, in the past two years, Li Xiu discovered that Li Shimin had begun to have some problems with Goguryeo. For example, he asked Feinusi to start collecting information from all aspects of Goguryeo. Even his Liangyi Hall was hung with a map of the Liaodong area, which marked many places, all of which were where the Tang Dynasty stationed troops in Liaodong. In addition, some important cities in Goguryeo were also marked.

Li Xiu knew Li Shimin very well, and he would never be interested in Goguryeo for no reason. In addition to Li Shimin's performance in the original history, Li Xiu was already sure that Li Shimin had already begun to plot against Goguryeo, so he asked Liu Rengui's opinion on how to attack Goguryeo.

Although Liu Rengui was a civil servant, the battle of Baijiangkou was really on the stage of history. During this battle, Liu Rengui also showed outstanding strategic vision. He also stayed in Hedong for several years and was very familiar with the situation there, so Li Xiu asked him about his opinion on the attack on Goguryeo.

Liu Rengui was shocked when he heard Li Xiu's words and vaguely guessed something, but he did not dare to think deeper. Then he was silent for a moment before speaking: "Although Goguryeo resigned to our Tang Dynasty, they had fought with the Central Plains for many years before, so they built a large number of strong town fortresses in the Liaodong area. These fortresses were built in a dangerous place. Only a small amount of troops could stop tens of thousands of troops. Therefore, if they attacked from land, they would probably cause heavy losses to the army."

When he said this, Liu Rengui paused for a moment before continuing: "Especially the winter in Liaodong is bitter and cold. If the fortress of Goguryeo drags down the army, when winter comes, the imperial army can only retreat. However, compared to land, it is completely different if it attacks from the sea. Especially, the capital of Goguryeo is not far from the coast, so if the army can land on the coast near Pyongyang, it will definitely have a surprise attack!"

"Good solution!" Li Xiu couldn't help but exclaimed when he heard this. Wars in this era only focused on land warfare. For example, a powerful empire as the Tang Dynasty, but there were only a few naval armies, and naval armies rarely fought on the water surface. The biggest role was to transport military supplies. It was not easy for Liu Rengui to think that crossing the sea to fight was not easy.

"But if you want to cross the sea, you must defeat Goguryeo's navy. Speaking of which, Goguryeo is not without any preparation for the threat to the sea. For example, there is an elite Goguryeo navy along the coast near Pyongyang. In comparison, although my Tang Dynasty navy is stronger, it is not easy to destroy them. Moreover, after the army crosses the sea, the navy also needs to support logistics. So I think the court should pay attention to the navy now and strive to make the navy stronger, so that the army crossing the sea has no worries!" Liu Rengui said finally again.

Li Xiu also deeply agreed with Liu Rengui's suggestion. The neglect of the navy was a common problem in the Central Plains dynasty. Not to mention anything else, it can be seen from the name alone. For example, whether it is inland rivers or on seas, as long as the Tang army is called a navy, and there is no name for a navy at all. Moreover, the warships used by the navy are also very backward. Although they are very tall, they are unscientific. The center of gravity of the warships is very high. If the wind and waves on the sea are bigger, the ships may capsize, let alone fight at sea.

Liu Rengui had a lot of ideas about the navy. In fact, the county he served was on the beach. Many people in the county made a living by fishing in the sea. There were a Tang Dynasty naval army stationed nearby, but the number was not large. He also found out about the situation inside the navy from the navy generals.

Li Xiu was very interested in the navy, to be precise, the navy, so the two of them chatted for a long time, but they didn't talk much about the financial management and supervision matters. They waited until it was getting late, and Li Xiu personally sent the other party back to the city.

Originally, Liu Rengui had just returned, and Li Xiu planned to let him take a few days off before going to the financial management supervisor, but he did not expect that he would come to the financial management supervisor early the next day and took the initiative to take on his own responsibilities. Li Xiu had no choice but to introduce what he had originally planned to assign to Liu Rengui.

Liu Rengui has a square character and is even a bit old-fashioned, which is not suitable for taking over the bank's business, so Li Xiu planned early to let Liu Rengui take over the minting of money. Liu Rengui has also been to several local minting bureaus along the way, and found many problems from it. So when Li Xiu handed over the minting bureau to Liu Rengui, he immediately made a suggestion.

"Integrated Money Making Bureau?" Li Xiu was stunned when he heard Liu Rengui's suggestion. He did not expect that Liu Rengui had just taken office and had such a big move.

"Mr. I have been to nine coin minting bureaus on the way back. As far as I know, there are no less than ten coin minting bureaus in Hebei alone. There are more in Hedong. These coin minting bureaus are big and small, and the quality of coins they cast is different. However, in general, large-scale coin minting bureaus have stricter quality management and better quality of copper coins produced. In contrast, the management of small coin minting bureaus is a bit chaotic. Not only is the quality of copper coins not guaranteed, but there will be even chaos in the accounts. Even if someone is greedy for it, it may not be able to find out from the accounts!"

When he said this, Liu Rengui paused for a moment and then said: "Actually, according to my estimation, our Tang Dynasty did not need to open so many coin minting bureaus. However, at the end of the Sui Dynasty, there were many heroes in all places. As long as people with ambitions were aware of the situation, they would open the furnace to cast coins on their own territory. Later, the Tang Dynasty unified the Tang Dynasty. Although many coin minting bureaus were abolished, many coin minting bureaus remained, such as there were no less than ten in Hebei. But in my opinion, only two or three larger coin minting bureaus were enough to solve the local coin minting matters."

"I really need to integrate the money minting bureaus in various places?" Li Xiu couldn't help but ponder for a moment when he heard this, and then said with some uncertainty. After all, this is not a small matter, especially the financial management supervision has just been established and there is no experience in all aspects, so Li Xiu has no confidence in integrating the money minting bureau such as such.

"That's true. The matter of minting is of great importance. However, there are not only many coin minting bureaus in various places, but also not large in scale. The management of such small coin minting bureaus is chaotic, and the quality of the coin minting cannot be guaranteed. Therefore, in the eyes of the Xiaguan, integrating the coin minting bureau is urgent!" Liu Rengui said with great affirmation again.

"But our financial management supervisor is not only lacking in manpower, but also having no experience. Now, if there is such a big thing in the Money Making Bureau, if something goes wrong, it will probably hit the reputation of our financial management supervisor and may even affect the bank's affairs?" Li Xiu finally expressed his worries at this time. For him, the entire financial management supervisor revolves around the bank, so the Money Making Bureau should not affect the bank.

"Mr. Prince Consort, although I don't understand the matter of the bank, I know that the core of the bank is copper coins. If the matter of the Money Mason is not resolved, it will definitely affect the bank in the future. Moreover, the matter of integrating the Money Mason is not complicated. The key is to have the support of Your Majesty and the determination of the Money Mason. As for the next thing, the official is willing to take it all!" Liu Rengui also showed a confident expression when he spoke at the end. It seemed that he had been thinking about integrating the Money Mason for a long time.

"Then what are you going to do?" Li Xiu was also a little moved when he saw Liu Rengui's firm expression, so he thought about it and asked.

"The fastest way is to select officials from the prison to dispatch them to various places, thoroughly investigate the situation of the money minting bureaus in various places, and then merge or lay off some small money minting bureaus based on the local situation. However, now the prison is insufficient, and there are probably not many officials who can be assigned to me by the prince consort, so I plan to start from Chang'an, Luoyang and Taiyuan, and after the integration of the money minting bureaus in these three places, then expand to other places!" Liu Rengui explained slowly.

"Is this a bit too slow? I don't think we should report to Your Majesty and ask the governments from all over the country to assist. This should speed up the integration of the money minting bureaus in various places." Li Xiu suddenly thought of a solution and immediately suggested.

"No!" What Li Xiu didn't expect was that Liu Rengui opposed without hesitation.

"Why?" Li Xiu couldn't help but ask in a confused manner when he heard this.

"The prince-consort has not served in the local area, so it is normal for him to not understand the local affairs." Liu Rengui said with a serious expression at this time, "The prince-consort established a financial management supervisor and asked His Majesty for the power of minting money. The following officials seem to the prince-consort to make the power of minting money independent of the local area and then the court will manage it uniformly. But if the prince-consort let the local governments intervene in the integration of the money minting bureau, then these integrated money minting bureaus will definitely be mixed, and I don't know how many forces will be placed. In this way, our financial management supervisor will not be able to completely control the money minting bureaus in various places!"

Li Xiu finally woke up when he heard Liu Rengui's words. It turned out that Liu Rengui's integration of the Money Making Bureau was not just for unified management and ensuring the quality of copper coins. The most important thing was to use the integration to completely control the Money Making Bureaus across the country in the hands of the Financial Management Supervision. In this way, Li Xiu's orders can be smoothly issued to the Financial Management Supervision Bureaus in various places in the future.

"I understand, just do what you said, don't be afraid of offending others. I will take care of you if there is anything!" Li Xiu made a decision immediately and said. It seemed that he had thought it was too simple before. In contrast, an experienced official like Liu Rengui was more thorough in thinking.
Chapter completed!
