Blocked by the U.S. Federation in chips and related industries, before 2011, Huaxia's nano microsculpture technology has always lagged behind the international level, but after the signing of the mutual assistance treaty at the G17 Summit, the U.S. Federation broke the blockade of chips against China, and China's technological innovation in related industries has advanced by leaps and bounds.

Up to now, 500 million 40nm MOS tubes have been made on 15mm*15mm square silicon wafers by using nano micro-engraving technology, and the production principle is to leave traces by laser etching silicon wafers, and cover the designated area with a shading mask, so that accurate traces can be etched on the silicon wafers, and the silicon wafers can be manufactured in batches by coating the oxide layer and metal layer after the silicon wafers are etched and repeatedly etched.

The technical bottleneck faced by Huaxia in the past mainly lies in mask manufacturing, not in chip production, because mask requires higher precision machines to process slowly, which is not only extremely costly, but also infuriating that under the deliberate blockade of the United States, no matter how much Huaxia pays, it cannot obtain high-precision processing machines.

Fortunately, these are not problems now, and now Huaxia has successfully broken through the technical barriers, and the most advanced etching technology can even etch a 7nm MOS tube.

This is an accuracy far beyond the reach of human eyesight, imagine if a high-power laser is used to etch a block or piece of silver with conductive silver paste, is it possible to engrave billions of runes on a silver piece the size of a fingernail like an engraved chip?

If so, what kind of effect would it have? Even if you can't do it, with the help of Zero One to build a digital model, 3D printing technology, and micro-engraving printing with silver powder and other bondable materials, you can easily mass-produce runic utensils that are difficult for even grandmasters to make.

As long as you can master the knowledge system of using runes, with the existing technology, you can easily break through the ceiling faced by rune civilizations in terms of quantity and quality.

Of course, these things don't have to be told to Mohuan for the time being.

After the experiment was a complete success, Yang Xiaoqian called up the surveillance screen in the lounge again, so that Mo Huan could see that the Mo family children he was worried about were eating, drinking, and having fun in the lounge.

When Mohuan lamented that the scientific and technological creations were as magical as the Rune Avenue, Yang Xiaoqian proposed that the two sides should cooperate, communicate with each other, take what they need, and achieve common strength.

Both sides had the intention of exchanging technology, so they naturally hit it off, but after the initial verbal agreement, Yang Xiaoqian did not rush to implement the specific terms.

Anyway, Mo Huan and the children of the Mo family are in the hands of Huaxia, and it is impossible to have any contact with powerful countries such as the United States Federation, so Yang Xiaoqian is not in a hurry to strike while the iron is hot, and the specific cooperation agreement and terms can be left for later.

As for now, making friends with this young Mo family grandmaster is the highest priority.

And in the matter of "making friends with visitors from different human civilizations", Yang Xiaoqian happens to be the most experienced person in the world.

So the two chatted in the conversation room under the translation of Zero One, and improved their understanding of each other's worlds.

During the conversation, Yang Xiaoqian found that although Mo Huan and Yu Qian's personalities, temperaments and ways of thinking were very different due to their growth environment and personal experience, the two maintained a high degree of consistency in one point, that is, eating.

After a long conversation all night, I not only ate a full banquet of the Manchu and Han people, but also ate a flowing water banquet composed of representative snacks from various provinces and cities. Although Mo Huan, as a direct descendant of a top family, has also tasted all kinds of delicacies in the other world, it is obvious that the cooking methods of the other world are quite monotonous, and the vast and profound Chinese cuisine has successfully conquered the mouth and stomach of this young grandmaster.

When Mohuan was full of praise for snacks from all over the world, the military leaders who were listening outside the conversation couldn't help but make a joke, saying that in this meeting between the two sides, Huaxia cuisine has made indelible contributions to promoting friendship between the two sides and laying a good foundation for cooperation.

Considering that there may be contact with visitors from other worlds in the future, the Secrecy Bureau has submitted a number of plans, and suggested summing up experience and developing a set of methods for friendly communication with visitors from other worlds. After the military leaders made this joke, the representatives of the Secrecy Bureau, who were also observing, secretly kept the joke in their hearts and prepared to put it into the plan.

Most of the military leaders who joked didn't expect that because they had inadvertently made a joke, in the process of many subsequent contacts with humans from other worlds, Huaxia officials always regarded the first wave of food offensives as the vanguard.

The appearance of Mohuan gobbling up is quite infectious, Yang Xiaoqian is in a good mood, and his appetite is also good, the two chatted while eating, in addition to the food of the two worlds, they also talked about humanities, society, folklore, military, politics and other topics.

According to the description of the ink ring, coupled with the conception, supplementation and reasonable restoration of the expert team, Yang Xiaoqian gradually developed some basic concepts about the fourth earth from which the ink ring came.

As Yang Xiaoqian once predicted, Earth No. 4 got the "exam papers" tens of thousands of years ago and began to "answer questions", so the human beings of Earth No. 4 have embarked on a completely different trajectory from Earth No. 1 from the beginning, even if the world is different, it is not enough to describe the difference between the two in the fields of history and humanities.

Due to the frequent occurrence of geological disasters, the basins and plains of all continents, which were supposed to be the cradle of civilization, have become thousands of miles of countries, and the number of human beings has been greatly reduced, and there is no stable living environment, so it is difficult to form a stable society. Since then, the human civilization of Earth 4 has been moving towards a spiral of uncertain future, and even if it is advancing, it is limited, and if it is unfortunate enough to encounter a new round of disasters, it will take great strides backwards.

This continued until the birthplace of the rune civilization, the Celestial Ring Clan.

According to historical records, the Tianhuan tribe comprehended the mystery of the runes in the bones of a "silver giant", and from there they walked towards the road of runes.

Then, for some reason not recorded in the history books, the prosperous Tianhuan tribe collapsed overnight and turned into nearly 100 tribes and families.

The so-called tribes are similar to the tribes as Yang Xiaoqian understands them, they are all ethnic communities that are ahead of clans in social form, tribes but lag behind nations, some tribes are primitive commune systems, and some tribes are semi-slave societies.

In the world where the ink ring comes from, the family is much higher than the existence of ordinary tribes, because the clan only knows how to use rune tools to fight and fight, while the family has the supreme meaning of runes.

Because the semi-primitive society of the tribe was destined to make it difficult for them to grow crops to feed the expanding group, they had to conquer the outside world in addition to planting crops, picking wild fruits, and hunting wild beasts, and the objects of conquest could be the demons entrenched in the wilderness, or they could be each other.

Therefore, the tribe is always born or extinguished in the war, and it is difficult to have the conditions to produce a complete knowledge system, let alone pass on the knowledge system accumulated by the ancestors, and often only the family can retain the knowledge and pass it on from generation to generation.
