Gao Ming in the selection of talents, the first thing to pay attention to is character, followed by talent, because in his view, talent can be cultivated, but character is difficult to change.

This is also the reason why people often say that "the country is easy to change, and the nature is difficult to change".

For those who have talent but poor character, Gao Ming will put him under his nose and stare at him all the time.

For example, the Sugan Chengji is such a type.

There are only people who can be trusted by Gao Ming, he can release them, such as Li Goudan and Zhang Sizheng and others, even if they don't see them for a few months, Gao Ming is very relieved.

And Ye Feng is obviously also a person who reassures Gao Ming.

At the beginning, Gao Ming asked him to escort the prisoner and his family to Lingnan, and at the same time gave him a task, which was to find a precious material in Lingnan and its vicinity - rubber!

In fact, Gao Ming is not sure whether there are rubber trees in Datang, but he thinks that if there are, then they will only appear in tropical areas like Lingnan.

Although the journey from Chang'an to Lingnan is long, with Ye Feng's speed on horseback, half a month is enough for him to run a round trip, but it took him more than four months!

Gao Ming didn't think that Ye Feng would be a lazy person, so in other words, he did spend more than three months looking for the rubber tree, but unfortunately he didn't find it.

It can be seen that there are indeed no rubber trees in Datang at this time.

After getting this answer, Gao Ming really felt a little regretful, but he wouldn't blame Ye Feng for this, after all, how could Ye Feng find something that didn't exist?

Therefore, when Ye Feng pleaded guilty to Gao Ming again because he didn't find the rubber, Gao Ming immediately smiled.

"Ye Feng, this time I made a mistake in judgment, there may not be rubber trees in Lingnan, so you don't have to blame yourself too much."

Hearing Gao Ming's words, Ye Feng once again showed a touched look, and he immediately hugged his fist towards Gao Ming again.

"Thank you Your Highness for your trust, but please ask Your Highness to forgive your subordinates for some more time, your subordinates plan to take people to continue to search for the west, maybe ......"

"No need!"

The origin of rubber trees is in South America, and even if Ye Feng goes further west, at most it will reach India, which is still 108,000 miles away.

So before he could finish speaking, Gao Ming smiled and waved his hand at him.

"Since there is no Lingnan, it is futile to go further west, so there is no need to look for it."

"Yes!"

Since Gao Ming had spoken, Ye Feng could only nod his head and say yes, but at this time, he suddenly remembered something, and hurriedly took out a mass of gray-brown things from his arms and handed it to Gao Ming.

"His Royal Highness the Prince, this is what his subordinates found when they came back through Jiangnan West Road, although this tree is different from the rubber tree described by His Highness, but his subordinates found that there is also rubber similar to what His Highness said in its bark and roots!"

Hearing Ye Feng's words, Gao Ming suddenly became interested.

"Something like rubber? Show me! ”

"Yes!"

Gao Ming took the thing from Ye Feng's hand and looked at it, and immediately couldn't help but show a shocked face.

"Is this plastic? No way! How could there be such a thing in this day and age! ”

At this moment, Gao Ming suddenly felt that his three views had been impacted, but he quickly reined in his mind and forced himself to calm down.

"Calm down...... Calm down...... There can be no plastic in this day and age, this thing must be something else! ”

Thinking of this, Gao Ming immediately set his eyes on Ye Feng.

"Ye Feng, you just said that this thing was obtained from the bark and roots of the tree, right? Then I ask you, what kind of tree is this? How did you get it? ”

Hearing Gao Ming's words, Ye Feng hurriedly saluted him.

"His Royal Highness the Crown Prince Qiqi, this tree is called Eucommia, and his subordinates took its bark and rhizomes to dry, then grind them into powder, and then bleached the sawdust with water, and then got this thing."

"Uh......"

But when Gao Ming heard Ye Feng say the word "Eucommia", he understood that this thing was Eucommia ulmoides gum, and when he heard Ye Feng's method of obtaining Eucommia gum, he couldn't help but laugh.

"Hahahaha, I can even come up with a grinding flotation method, it's not easy, not bad!"

Eucommia ulmoides is known as "Chinese rubber", and the composition of eucommia gum is the same as that of rubber, but there are certain differences because of the different molecular compositions.

At low temperatures, the properties of Eucommia ulmoides gum are more inclined to plastic, and at temperatures higher than 60 degrees, Eucommia ulmoides gum has the same ductility as rubber, that is, Eucommia gum is a material that has both plastic and rubber properties.

Gao Ming asked Ye Feng to look for rubber, in fact, he just wanted to use it to make carriage tires, but now Ye Feng has found Eucommia ulmoides glue, so Gao Ming can use the characteristics of Eucommia ulmoides glue to make molds, and then use molds to make high-precision machines.

Like the steam engine!

Gao Ming knew how important the steam engine was to enhance the national strength of Datang, not to mention anything else, as long as the steam engine could be brought out, Gao Ming would be able to build a steam engine ship, so that Datang's ships could get rid of their dependence on wind and manpower.

As long as you have such a big ship, whether you go to North America to find corn, or South America to find potatoes, or conquer Southeast Asia to establish colonies, everything is not a problem!

But it's a pity that Datang's technology and technology can't reach the level of making a steam engine, because the precision of the machine is not enough, and the sealing and steam utilization rate are at the bottom.

But with Eucommia ulmoides gum is different, even if the machine is unqualified, Gaoming can also use the stability, plasticity and memory of Eucommia ulmoides gum to correct, and make the machine or accessory model you need.

Next, take these accurate parts models as samples, and use ceramics or burning-resistant clay to make the corresponding molds, as long as you have these molds, you can naturally make high-precision machine parts!

One is just a carriage tire that can provide relative riding comfort, and the other is a high-precision machine mold that can enhance Datang's national strength.

Therefore, for the current Gaoming, the value of eucommia gum is much higher than that of rubber.

Looking at the goose egg-sized ball of eucommia gum in his hand, Gao Ming's eyes were full of joy.

"This is really intentionally planted flowers and flowers, unintentionally planted willows and willows, with this thing, the accuracy of the cylinder wall and the live and plug ring of the steam engine is no problem, a good eucommia, a good eucommia gum, hahahaha!"

Gao Ming laughed and patted Ye Feng's shoulder.

"Ye Feng, you did a very good job this time, I am very satisfied, say, what do you want? Even if it's a rare treasure, as long as you open your mouth, I'll find a way to get it for you! ”

Seeing Gao Ming so happy, Ye Feng also knew that he had given the right treasure, so he also grinned.

"His Royal Highness the Crown Prince has won the award, and his subordinates have received the kindness of His Royal Highness, and it is difficult to repay it in this life, but ......"

Speaking of this, he suddenly secretly glanced at Yun Jin who was standing next to him, and then blushed and hugged Gao Ming.

"My subordinates are courageous, I implore His Royal Highness the Crown Prince to give his subordinates a place to live in peace, my subordinates want to marry Yunjin as soon as possible, and I ask His Royal Highness to agree!"

After speaking, Ye Feng slammed towards Gao Ming to the ground.
