Gao Huan was very happy when he heard that He Bin brought back rubber and rubber tree species.

Not long ago, Song Yingxing asked Gao Huan to visit the steam engine at the Ministry of Industry. At that time, the Ministry of Industry used Eucommia ulmoides glue to solve some problems with the steam engine.

However, not long after, the Ministry of Industry and Technology Hospital sent back news that there was a problem with the rubber pads and rubber rings made of Eucommia ulmoides, and their service life was relatively short. The Ministry of Industry and Technology also needed to redevelop new Eucommia ulmoides formula to improve the service life.

Gao Huan didn't understand these things, and just felt that there must be some reason why history chose rubber in the end.

Now that rubber is back, you can immediately ask the Ministry of Industry to conduct experiments and compare them. When the results are released, you can take advantage of this time to convene a meeting of the vassal states and lay out the rubber plantation.

After all, the growth of rubber trees takes time, and it takes seven or eight years to mature rubber cutting, so planning must be carried out as soon as possible.

Gao Huan couldn't help but ask, "Where are people now?"

Du Yinxi replied, "I just left Macau and was already on my way to Nanjing."

Gao Huan nodded slightly, "When someone arrives, I will bring you to see me immediately."

"As for your order!" Du Yinxi bowed slightly.

Gao Huan then looked at everyone and asked, "Is there any other matters?"

At this time, Song Xiance said: "Your Majesty, I have something. Dorgon submitted a memorial to the court to relocate five thousand Longwu's flintlock rifles, as well as the supporting gunpowder and lead bullets. Will the court approve it?"

The Han army was transferred to the northwest border and was preparing to pursue the escaped Prince Sima Yi of Yarkand, and competed with Tsarist Russia for control of Central Asia. Their strength really needed to be strengthened.

Gao Huan nodded: "The situation in Central Asia is quite complicated. There is Persia to the south, the Ottoman to the west, and Tsarist Russia to the north. All the things they want are granted to them."

Song Xiance nodded and sat down again, "I understand!"

After Zhou Yanru was moved to the Council, there was a lack of a political discussion that could be without a bottom line. He followed Gao Huan's arrangements and understood Gao Huan's wishes. Gao Huan thought about it and thought that Song Xianshu could replace him, so he put him in the Council.

Gao Huan immediately said, "There is no other matter, so let's continue yesterday's topic. My dear friends think all night, what can I teach you today?"

Now the Qian Dynasty is peaceful inside and there are no major wars outside, but it does not mean that the world is peaceful and there is no need to fight again.

If you are wary, you will die; if you forget to fight, you will be in danger.

The Western world is about to rise and the Eastern world is about to revive, and the collision between the two sides is inevitable. Over the years, 80% of the conflicts between the eldest and the second may evolve into wars between the two sides.

Now, the Qian Dynasty is developing its economy and production internally, and clarifying its relationship with its vassal states externally, is actually preparing for the upcoming war.

Yesterday, Gao Huan raised an issue, how to strengthen control over vassal states?

When the Central Plains dynasty was strong, those vassal states sent envoys to court to maintain vassal relations. When the Central Plains dynasty was invaded by foreign enemies, they would watch the walls. After the new dynasty was established, they would send envoys to court to court, only enjoying the benefits and not bearing obligations.

Gao Huan was obviously very dissatisfied with the previous tribute relations and hoped that he could make changes in the Qian Dynasty.
