This time, Yang Yifei bought 23 days of time in the biochemical world, during these 23 days, in addition to going to work in the president's office every day, living a normal life with Alice, and occasionally going to various places to visit Alice, he would fly to all over the world to draw weapons and equipment and various resources whenever he was free.

Because of the presence of so many Alices, when he suddenly disappeared for a while, no one would feel strange, because they all thought that he had gone to one of Alice's.

There will be no one to find out which Alice he went to, and it is impossible for Alice to get together to discuss this matter, because it is suspected of showing off, and it turns out that this has become the best cover for Yang Yifei to do private work.

Because there are 23 Alices, he bought 23 days off, which is exactly one a day.

This time, he replenished a lot of weapons and equipment that he had not prepared before, such as anti-aircraft machine guns, 152 howitzers, 122 rocket launchers, large transport helicopters, and so on.

33 of his 35 helicopters were left in the Dark World, leaving only one Black Hawk and one Apache in the storage space, as were tanks and armored vehicles.

This time he replenished 20 Apaches, 30 Black Hawks with more than 200 bases of ammunition each, 100 assault vehicles, 60 infantry fighting vehicles, 50 tanks with 100 bases of ammunition each.

He prepared 50,000 pieces of individual equipment, and the ammunition reserve was no less than 1 billion, and he still chose Russian standard equipment, the reason is still that, because the structure is simple, easy to maintain, disassemble, and manufacture.

In addition, he has produced hundreds of Perfect T viruses, and now the reserves of Perfect T viruses have exceeded 1,000.

He made the perfect T-virus, he did it at the mothballed base in Las Vegas, which has been permanently mothballed and is now Yang Yifei's independent laboratory.

At the end of the break, he also copied the full set of experimental equipment and prepared to take it to the Overworld.

In addition to weapons and equipment this time, he also looted a large number of building materials and construction machinery, especially the prefabricated house, which he didn't expect before, but he didn't remember it until he returned to the main world, and he spent a lot of unjust points.

There are also metal materials such as steel, copper, tin, aluminum, tungsten, titanium, zinc, rubber, soft and hard plastics, etc., and he also has a lot of them, with which it is convenient to make anything.

Coupled with the abundance of magic crystals, mythril, gems, yew wood, ebony and other magical materials in his storage space, he can make magical artifacts in any world.

After 10 days, Yang Yifei returned to the system space and went to the mythical world again.

This time the dark world has gone through 5 years, and he has recovered the 5 years of Jiuyang True Qi cultivated by the projection, and now his Jiuyang Divine Skill has 30 years of cultivation.

At the same time, all kinds of magical knowledge were brought to the projection, and Daqin was still recuperating in the past 5 years, developing national strength, and actively stockpiling war resources.

In the past 5 years, Yang Yifei's projection has improved the level of steelmaking, and Daqin has completely transitioned from the Bronze Age to the Iron Age.

Iron weapons and armor have finally surpassed those of bronze, not only becoming sharper and tougher, but also much lighter.

All standard weapons are single knives in the shape of katanas, which are slightly wider than katana blades and have more powerful slashing power.

The long-handled weapons were all changed to horse lances, and now Daqin's steel production has increased significantly, and the steel reserves are sufficient, and there is no need to use cheap goods such as spears.

The warhead of the lance is long enough to pick and slash, and it has the characteristics of both a spear and a broadsword.

Only a small part of the obsolete bronzes were preserved and placed in the history museum proposed by Yang Yifei.

The others were taken back by the imperial court and cast into 12 golden figures, standing around Xianyang Palace, as if 12 huge golden armor heavenly generals were guarding Xianyang Palace.

After this 5 years have passed, Yang Yifei's next 5-year plan is to vigorously develop the level of medicine, establish a medical school, and study the surgical medicine of future generations.

The advent of glass contributed to the invention of microscopes and astronomical telescopes, and with astronomical telescopes, Qin Tianjian's gang of Taishi Ling, little by little, confirmed the "planet" theory that Yang Yifei said.

They discovered that the stars in the sky were really spherical, and what they had previously thought was a cake-shaped moon was also spherical.

Social development is advancing step by step, the first emperor has maintained the greatest enthusiasm for ten years, and Yang Yifei has also been trusted for ten years.

Because he does not form a party, does not engage in personal interests, does not even marry, and does not even have children, it can be said that he is a lonely minister who is dedicated to developing the country and assisting the king.

For such a courtier, the First Emperor really couldn't find a reason not to trust him, and Yang Yifei was also worthy of his trust.

This pair of monarchs and ministers is simply a model among monarchs and ministers throughout the ages, a wise and martial artist, a loyal and diligent, the most poems and songs written by the people in the world, is to praise this pair of monarchs and ministers.

……

After the rest time of the mythical world ended, Yang Yifei finally bought 5 days of rest in the Condor World, and he didn't do much in the Condor World, but collected the genes of more than 500 boys and girls, preparing to get back the cloned population of the main world.

When everything was ready, he returned to the Overworld.

Because Yang Yifei can only enter the world he has experienced after the end of the experience, and it is not possible when the experience is opened, so every time he finishes the experience, he must make all preparations before leaving the system space.

Nine months have passed since they escaped from the mine and come to this grassland, and Ma Yan has basically returned to the shape of a normal teenager under the care of good food and good exercises.

Ma Yan is now 173 tall, with a smooth body, two chest muscles and six abdominal muscles with obvious outlines, and a very handsome appearance.

In 5 months, he has completed the first volume of the Jiuyang Sutra, and the second volume has also completed half of the practice, and this qualification is not inferior to Zhang Wuji.

After Yang Yifei returned to the main world, he went to see Ma Yan, and saw that he was still cultivating diligently, so he took care of himself and went to work, to his surprise, there was no heaven and earth aura here, but there was no shortage of various elements.

In this way, the elements and the aura are really not the same thing, the elements are pervasive in the whole universe, everywhere, everywhere, but the aura is not everywhere.

The aura is born in the Great Dao, but the elements exist according to the laws of the universe, where there are laws, there are elements, and the laws of the universe naturally envelop the entire universe.

The law and the avenue are not the same concept, the law of the universe is the rule of the operation of the universe, if there is no law, then the universe is static and has no vitality.

Without the law of wind, there would be no wind in the world, without the law of thunder, there would be no thunder and lightning, and without the law of fire and water, there would be no element of fire and water in the world.

The law can be said to be the way of heaven, but it has nothing to do with the Great Dao, some people compare the way of heaven with the Great Dao, and even think that the way of heaven is born in the Great Dao, and the Great Dao is above the way of heaven, which is not right.

The way of heaven is the way of heaven, the way of heaven is the way of heaven, the concept is fundamentally different.

The Dao of Heaven is the operating rule of the universe, and it naturally exists since the formation of the universe, while the Dao represents the power, or the ultimate of ability, but it existed before the universe was formed.

The ultimate representative of the Three Thousand Great Roads is the Three Thousand Demon Gods who existed in the chaos before the formation of the universe, each of them controls a Great Dao, and they are the ultimate embodiment of that Great Dao.

The Fire Chaos Demon God is the ultimate embodiment of the Heavenly Fire Dao, but the Heavenly Fire Dao cannot represent all the flames in the universe, it can only be said that it is the highest existence in the flames.

However, the law of fire can represent and even drive all the fire elements in the universe, and as for the strength of the fire element, it is naturally determined by cultivation.

Another example is the Chaos Demon God of Force, which controls the Avenue of Force, which represents the ultimate embodiment of power, there is a fire element in the laws of the universe, but there has never been a "force element".

Therefore, the difference between the Heavenly Dao and the Great Dao is clear at a glance, the Heavenly Dao and the Great Dao are related, but they are actually two completely different things.

The Great Dao can be the strongest embodiment of a certain Heavenly Dao Law, but it can never represent the Heavenly Dao, and the Universal Law represents the Heavenly Dao, but it can raise a certain law to the level of the Great Dao.

That's the connection between them, so it's very normal for elements to exist where there is no aura.
