In Roland's view, most bureaucrats like Semyon Ivanovich lack innovation, pay attention to superficial skills, have the advantage of being good at handling complex interpersonal relationships, mediating the interests of all parties, and have a good understanding of grassroots business, and can meet their superiors and be down-to-earth, they are indispensable lubricants in the bureaucracy, and they are suitable candidates for managing the Karon Industrial Zone.

Of course, most old fritters like Semyon Ivanovich can't be honest as water, blatant corruption and bribery may not dare, but gray income is indispensable, Roland doesn't care much about this, the water is clear, there is no fish, as long as this guy can do the things he explains, he will turn a blind eye to a little oil and water.

Semyon Ivanovich ran a few steps forward to lead the way for Roland, and by the way, he gave him a guide to introduce the planning of the industrial zone.

Karon Industrial Park is built along the river and the park is still undergoing infrastructure construction. Most striking was a strange machine, powered by a roaring magic steam engine, dragging a huge cast iron drum against the ground, making the muddy ground as if it had been ironed. Workers followed, laying bricks on the flat, hard ground.

"That's the steamroller of this world." Roland thought to himself, and stopped to look at it a few more times. As a result, the oddly shaped "magic guide roller" was very uncompetitive, and it broke down after a while, and the mechanic who was the part-time site supervisor ran over to check it, and reluctantly announced: "The wheels are broken again, finish paving this section of the road, and then rest for half an hour!" ”

With a gloating laugh, the workers quickly paved the road to where the roller had broken down, and then sat down in groups to light a bucket of cigarettes, smoking and chatting as the mechanic and his four apprentices busily repaired the magic roller.

His Royal Highness the Prince, who came to inspect it, saw this disappointing scene, and Isaac's face was a little ugly. However, to his surprise, Roland did not show anger, and was very curious to talk to the mechanic and ask what was wrong with the roller.

"Wheel bearings are broken, which is a very common failure, and it always breaks once or twice a day." The mechanic replied with some reluctance.

"Isn't there a better way to solve this problem once and for all than to replace the bearings?" Antron interjected, "Like reinforcing the bearings with spells?" ”

"It's not as simple as it seems, sir, reinforcing the bearings requires a high-level trick, and even a kind warlock who is willing to help with reinforcement won't be able to solve this kind of failure at the root."

"Why can't it be completely solved?" Roland asked.

"Look at our compactor, it's huge, it's very heavy, the wheels carry this behemoth on the undulating ground, not only need to withstand great pressure, but also have to endure frequent and violent shocks, the driver of the car will be dizzy and vomit as long as he continues to work for an hour, the wheels and bearings can not withstand even if they are reinforced with the best steel and spells, and they will break after working for three to five days at most." The mechanic patiently explained.

"So it's not enough to just increase the strength of the material, the key is to find ways to reduce the vibration of the wheel bearing." Based on the mechanic's explanation, Roland deduced, "Is there a way to absorb shocks?" ”

"It's a pity that there are no really effective shocks yet," the mechanic shrugged, "at least I've never seen a good shock, and I just hope that the clever mechanics will solve this big problem soon, and our project progress will not have to be delayed again and again." ”

"You don't have to rely on a warlock to solve a problem, a mage is more creative." Antron said disapprovingly. In his opinion, most of the work of the mechanism warlock has no technical content, and the major technological changes in the magic industry still have to rely on the exploration and theoretical innovation of the mage in the frontier field...... The vision of the masses of the people needs to be improved.

"It doesn't matter if you're a warlock or a mage, as long as someone can solve the problem." The mechanic said nonchalantly.

Roland squatted on the side of the road to observe the dismantled shell of the magic guide roller, large and small bearings and gears made up the internal organs of this huge machine, the complexity of the structure brought him a strong visual impact, and he couldn't help but recall the scene he saw when he walked into the car repair shop before the crossing.

The earth's automobile also gradually evolved from the rudimentary structure of the horse-drawn carriage to a sophisticated and reliable one, and eventually evolved into an industrial work of art. And how did the pioneers of the automotive industry solve the problem of damping? Roland knew very little about the construction of automobiles, but vaguely remembered a few related words such as springs, suspension, and hydraulics, and it was a fool's dream to invent a shock absorption system based on them.

Giving up those unrealistic thoughts, Roland looked down at the wheels of the magic guide roller, and was surprised to find that this thick iron ring with spokes actually had no tires, no wonder it was so bumpy to run!

If you think about it, there is no word for "tire" in Vares's lingua franca of humanity, so hasn't anyone in this world invented something like a tire?

Roland immediately asked Antron and the others if they knew about tires, and even after a while of comparing and explaining, they finally let everyone have a preliminary understanding of what tires are, and the result was not surprising, no one knew what it was, let alone what it was for.

Well, Varess didn't have the invention of the tire yet, so what about the materials from which the tires were made? In view of the fact that there was no petrochemical industry in this era, Roland did not consider synthetic rubber at all, and directly inquired about the existence of natural rubber.

After some painful exchanges, Antron, Semyon, Isaac, and the mechanic finally figured out what Roland was talking about as a tree that could shed glue-like sap.

"Your Highness, I have not seen this kind of tree you are talking about, but I have heard that there seems to be a similar plant in the hot climate of Grabelen in the southern part of the New World, as to whether the secreted sap can be used to make that ...... I don't know what kind of fetus it is. "Isaac, who has always seemed reticent, gives the only valuable information.

"Grabelen......" Roland sighed. Grabelen was so far away from the Far East that it had to abandon the search for natural rubber for tyres, leaving the problem to be solved in the future.

It took the mechanic half an hour to fix the roller with the help of his apprentice, and the steel monster let out a deafening roar again, dragging solid cast-iron rollers over the riverbank wasteland. The workers also had enough rest, jumped up and got to work.

Roland no longer bothered the busy people, and walked along the river beach under the guidance of Semyon.

A large area of wasteland on the river beach has been zoned into the industrial zone, although the road level and factory construction have not yet been completed, the planned plots have been circled with lime powder, neatly lined up along the Bailu River, covering an area of large and small, and also made of lime powder to make digital markings, which looks particularly weird.
