The results of the academic examination were announced, and the universities prepared admission letters and sent them to each admitted student, which seemed to be very ceremonial.

Although it is not possible to manage the household register by means of the information age, because of the reason of the castle, the household register is directly recorded in the castle palace.

Bai Tu also specially explained that university admission is the top priority, and officials from all over the country should actually review the comparison between the identity and the information of Chengji, and if there is fraud, severe punishment will be imposed!

Because of the limited number of places admitted to the university, a large number of students have failed to make the list, so they can only return to their hometowns, or prepare for a different path, or prepare for the next year - the academic examination is different from the triennial imperial examination, which is held every year.

And the scholars who were admitted were happily waiting for the start of school in August, and their joy was no less than that of the imperial examination!

After the study examination, the highlight of the Chu State was the imperial examination at the end of October.

It is still the six ministries and one hospital that have their own questions, and this time Pang Tong even became a dead horse doctor, and put the "selection of insulation materials" in the imperial examination of engineering.

In the impression of Bai Tu, it goes without saying that the best insulating material is synthetic rubber.

However, that thing needs oil, and there is no hope in the world of Johime, and the substitute is naturally natural rubber, which is limited in production.

With the industrialization level of the Chu State, as long as there is natural rubber, it will be enough to get through the current stage, and then ...... Bai Tu can only say that children and grandchildren have their own children and grandchildren!

After all, because of the hidden nature of fossil resources, as well as the existence of true qi and spiritual power, the Chengji world is destined to be unable to copy the development process of the world that Bai Tu is familiar with, so the dividends of the ...... "hard disk" are also disappearing faster.

Of course, in fact, there are many small inventions, there is no time to "click" out before, and at least the hard disk has the role of guiding the general direction, just like the "real gas engine", the actual technology has nothing to do with the content in the hard disk, but it has taken the road that the steam engine in the hard disk has been flattened.

However, even if it is natural rubber, it is not something that you can have if you want to have it, all kinds of rubber trees are not produced in the Han Dynasty, but only in the Golden State!

Naturally, Gan Ning went to sea this time, and the "rubber tree" was also one of his goals.

Just considering that there is no civilization in South America yet, even if there are human tribes, it should be a very primitive stage, there is no writing, and it may not even reach the Neolithic Age.

Therefore, it is not easy to find rubber trees in a short period of time - it is much more difficult to find crops such as corn.

After all, those crops, as long as you find the Mayans, even if you find them, and the rubber trees ...... I have to go to the deep mountains and old forests to drill by myself!

And Gan Ning can stay for a limited time this time, and he will find it sooner or later, but he may not be able to find it this time.

If Gan Ning can bring back the rubber trees this time and transplant them successfully, he can also go to the Golden State and let the second group of pioneers collect wild rubber trees......

I believe that it won't be long before the industrial projects that need to be sealed in the Chu State will be able to go further, and even the ocean will not be able to isolate the voice of the Chu State!

In addition, in fact, in Southeast Asia and the Qinling Mountains, there are also substitutes for substitutes......

Bai Tu had previously informed Shi Xie of the appearance of the ancient Tabo tree, and proposed that it was a plant needed by the Chu State, and asked the Jiaozhou Mansion to find it for him.

However, there is no news for the time being, after all, all ethnic groups in Southeast Asia have not yet used rubber, after all, in a narrow sense, the ancient Tabo tree in Southeast Asia is not considered a rubber tree......

Gutabo tree can also refine "rubber-like" substances, that is, Gutabo rubber, and even in terms of quality, the production of insulators is better than other natural rubber, which belongs to the main insulation force of submarine cables.

However, the ancient tapo tree is not a rubber tree in the real sense, and the yield of the ancient tapo gum used to refine it is smaller, and it will not flow out by itself, so it does not have the conditions for the use of natural means, and naturally there is no indigenous use.

As for other natural rubbers, they are all varieties introduced after Southeast Asia - the local climate is indeed suitable for growing rubber.

Although it is too late to plant a large area, because the ancient Tabo tree has not been used before, its wild quantity in nature is enough to meet the needs of the moment.

As long as you pay attention to sustainability, you can also pay attention to planting while collecting.

However......

Before Shi Xie completely decided to surrender to Chu, it was obviously impossible for the Chu army to enter the country on a large scale - what? You're here to look for trees? Do you think I believe it?

The number of Han Chinese registered in Jiaozhou was limited, and the number of troops was very small, but with the prestige of Shixie in Jiaozhou, he was fully able to mobilize the South Vietnamese tribes to help in the war.

It's not that strong, though......

However, the location and road conditions of Jiaozhou are natural protection, so that Chu State does not want to meet each other, otherwise it is easy to fall into it.

What's more, Shi Xie has been showing goodwill, but he hasn't made up his mind and completely surrendered to Chu.

To a certain extent, the conditions offered by the State of Chu to Shi Xie were much more stringent than those offered to him by Sun Quan in history.

He didn't plan to retain Shixie's right to rule in Jiaozhou at all, at most he gave Shi some convenience and preferential treatment in exchange, which is why at the beginning, Shi was even a little "rebellious".

It's just that after the state of Chu became stronger and stronger, Jiaozhou did not "rebel" for a long time, and now it is paying tribute year after year......

What Chu has to do is to keep building roads in the past, and when they reach his face, Shixie will only have one way to go to Chu.

Prior to this, the State of Chu was not ready to attack, and naturally it was impossible to bypass Jiaozhou and go to Southeast Asia to find Guta Boshu.

The same applies to "Eucommia".

Although the bark of Eucommia ulmoides in the Qinling Mountains can also be used to refine Guta gum, it ...... It was in the Qinling Mountains, and it was no less difficult to penetrate the forces of the Auxiliary Han and face the threat of the Wei State than to explore the Golden State by the navy.

And unlike the ancient Tabo tree, if Shixie discovers the ancient Tabo tree, with the current status relationship between Jiaozhou and Chu State, Bai Tu will give an order, Jiaozhou will definitely continue to collect raw materials and transport them to Chu State - of course, Chu State is not a forcible robbery, and it is easy to say that assistance in terms of grain and farm tools is easy to say.

But Qin Ling's words......

Even if Eucommia can be found, it will not be possible to trade on a large scale, after all, once the princes of all parties find out, they will "compete".

In addition, the gum content of the eucommia tree cannot be compared with that of real rubber trees, and it can only be extracted from the bark and leaves, and cannot be harvested every year by "tapping".

What Bai Tu is looking forward to most now is the rubber from the Golden State, at most, the freight is higher in the short term, but the output is more than enough to support the Chu State.

As for the present......

I can only look at Pang Tong, pitifully researching, how to use oil-soaked paper to achieve insulation, and use cloth and thread structure to achieve sealing.

……

The project of building roads to Jiaozhou has a very high priority in the road construction plan of Chu State, although the utilization rate is very low now, but the priority is second only to the official roads between several important prefectures.

And with the approach of the cement road, Shi's attitude towards the state of Chu became more and more attentive and docile.

It's been a long time since I mentioned that I want the Han family to give him a knighthood......

From this point of view, the road of Chu is not a loss - although from the perspective of "road", the use rate of this road is extremely low, but in fact, it has played an effect that tens of thousands of troops and several years may not be able to achieve.

After all, Shi Xie is not an ambitious person, and he is very sensible, and he doesn't think that he can pose any threat to the Chu State by jumping off the wall in a hurry.

If Jiaozhou is in the gap between Chu and other princes, at least there is an opportunity to use the vertical and horizontal way to survive among the powers, but the location of Jiaozhou is ...... Completely under the "wings" of the state of Chu!

If you want to lead other strong enemies to contain the Chu State, there is no room for operation......

Shi Xie is now very old, nearly 70 years old, plus ...... Among the younger generations, Shi Xie didn't see any talents, which also made him completely extinguish his desire to fight with the Chu State, and just wanted to seek more benefits for the Shi family.

Looking at the magical pavement of Chu State, which "turns straight into steel", has been paved all the way, Shi Xie also knows that there is not much time left for him.

And the state of Chu only built roads honestly, and did not move the army, which can be regarded as saving face and time for Jiaozhou to react.

In the second imperial examination of Chu this year, Jiaozhou also once again sent a key signal - Shi Kuang entered Chu and participated in the imperial examination.

Shi Kuang is the eldest son of the No. 2 person in Jiaozhou, "Shi Yi", and he is almost thirty this year, which is considered to be the older in the imperial examination.

As one of the core members of the Shi clan, Shi Kuang naturally has long been in Jiaozhou, and even Taishou - although the population on the household registration in the county is not as large as that of a county, but the size is also considered a Taishou.

Shi Kuang came to the State of Chu and participated in the imperial examination, not because of how strong his ability was, but to show the attitude of the Shi family!

Although this nominally has been a taishou, Bai Tu is very worried that he will fall off the list - it is not enough to be completely off the list, but as far as Shi Kuang is concerned, it is not very good-looking if he can't enter the gold list......

If he really has the talent to be too guarded, there is no problem in entering the gold list, after all, it is just a imperial examination for the election of officials.

However, the problem is that the Taishou of Jiaozhou is very extensive in governance, and there are very few Han people in their own nationality, and the people of the various ethnic groups in South Vietnam are generally guided and self-governed.

That is, to rely on both grace and power to make the tribes of the hundred tribes offer their ...... year after year The Shi clan is considered to have meritorious service in Jiaozhou, but it is still far from the "Sinicization of the Hundred Tribes", and it is not like the Chu State, which directly has the courage to build cities in Shanyue and Wuxi.

Measured by the standards of the Chu State, none of this kind of Taishou is qualified, and if he can be re-elected until the second year, he has to implicate the officials and scholars......

And in history, Shi Kuang not only had no opportunity to display his talents, but after Shi returned to Sun Quan, he went to Jianye with his father to be a proton, and ...... Extremely poor sensitivity to current situations.

After his cousin Shihui rebelled, Shi Kuang also believed in the evil of the counterinsurgency general Lu Dai, and really went to persuade him to surrender, but after the success, the Shihui family was destroyed, and Shi Kuang's father and son were also demoted to concubines......

For this reason, Bai Tu specially told the Ministry of Rites to send someone to probe the bottom of Shi Kuang in advance - fortunately, although it is lackluster, but after all, he has experience in governance, which is a great advantage among the scholars of the imperial examination, and the most important thing is that Shi Shi is worthy of being a heirloom of poetry and books, and in terms of scriptures and righteousness, Shi Kuang's foundation is very solid.

It is not difficult to let the Ministry of Rites release water a little, and let Shi Kuangjia Bang Dengke!

After all, it was the Shi clan who came to express his submission, and Bai Tu couldn't help but give face to others......
