In addition to the harvest of these cultivation resources, in the past few years, Ye Qiuli has also collected materials to refine many mid-to-low-grade elixirs and mid-to-low-grade spiritual weapons, and then he has refined several high-grade spiritual weapons without counting blood, not only timely transforming the materials and materials in the storage ring that no longer have much effect on him into magic weapons and pills that are still very useful to others, but also taking this opportunity to exercise his own alchemy making techniques.

Originally, he had already learned a lot of rare ancient secret methods from many masters of the Great Flood Kingdom's cultivation world, and then, when screening the cultivation materials of the Great Wilderness Country, he had seen many unique secret refining methods of various sects, all of which were precious secrets inherited from the earth's flood era, which not only greatly broadened his horizons, but also effectively improved the level of his alchemy device. The effect has also been greatly improved, and it can be almost raised by half a grade out of thin air.

It was in this situation that Ye Qiuli, who had been wiped out under the attack of the nuclear bomb, also rerefined a set of higher-quality guns. After the test of actual combat, he has found that these magic weapons of the formation flag are indeed very convenient to use, not only can they be used to trap the enemy and hurt people in ordinary times, but also can even play a role in protecting themselves and saving lives when it is critical, and it is indeed a very correct choice to be prepared.

After several years of busy work, although Ye Qiuli had not refined a lot of magic pills, the overall number was close to a hundred. Except for a few of these items that he had refined for his own use, most of the rest were gifts he had prepared for his family.

As a cultivator who has cultivated to the peak of the late Yuan Infant stage and is about to advance to the out-of-body stage, and at the same time is a good hand at alchemy, Ye Qiuli can't look down on the low-grade things in those spiritual weapons. Now, I'm afraid that only high-grade and top-grade spiritual weapons can enter his magic eyes. And the reason why he refined them was not only to prepare for his family's cultivation in advance, but also to thoroughly clean and sort out his storage rings.

After all, with his current cultivation and ability, as long as he successfully entered the cultivation realm with infinitely rich resources, most of the things could be obtained calmly, and the mid- and low-level materials that he had worked so hard to collect before did not need to travel thousands of miles to bring them over. The cultivation realm is different, and the standard of vision is naturally no longer the same, and it is indeed difficult for those ordinary items to be highly valued by him.

Although those things can't occupy much space in the infinite storage space of the Liuyun Immortal Ring, but as the so-called people make the best use of their talents, make the best use of things, and use good steel on the blade, for the Ye family who will be in the agile period and the golden pill stage for a long time, and the highest is not more than the Yuan infant stage, refining all those low-grade materials into the middle and lower grade elixir magic weapons can just fully meet their needs, killing two birds with one stone.

At this time, Ye Qiuli refined all those mid-level and low-level materials into magic weapons and pills and left them behind, obviously he could maximize their value and find the most suitable owner for them. Since he had decided to bring his family members to the Ancient Relic Star and lead them on the path of cultivation, he naturally had to be responsible for them to the end, doing his best to prepare as best he could, and doing his best to create the best cultivation environment for them.

In this way, in the alternation of busyness and leisure, Ye Qiuli has been very full and comfortable in the past 10 years. It's just that in the past few days, he has stopped all the affairs in his hands, looking up at the distant sky from time to time, and his expression occasionally reveals a vague anxiety and anticipation.

It turned out that not long ago, he received a message from the "Red Rabbit" spacecraft through the transit satellite densely scattered between the ancient relics and the earth: after 20 years of round-trip turning, it finally arrived safely on the earth, successfully picked up his family, and successfully traveled through the long cosmic space of 4 or 5 light years again, and was about to arrive at the ancient relics. The last few days are the dates when the "Red Rabbit" spacecraft landed on the ancient relics.

The ancient relict star is 4.4 light-years away from the Earth, and it will take 4.4 years to reach the Earth from here to relay the news back to the Earth, even if it is relayed through the relay satellites densely scattered between the two satellites. If you take into account factors such as the processing delay of satellites, Ye Qiuli estimates that it will take about 5 years to send back the information that he has discovered a suitable planet for life and notified them to immigrate.

And after receiving Ye Qiuli's message, the people of the Ye family on the earth did not stay for a moment, and immediately flew to the ancient relics star by spaceship, and it would take about 15 years to arrive at the earliest. After all, Ye Qiuli left the old "Red Rabbit" spacecraft on Earth with a maximum speed of 33% of the speed of light, and if he wants to fly 4.4 light years into space, it will take at least 13 or 14 years. In this way, when the time spent before and after is added, it is almost 20 years.

In this comparison, the time span is long, and the nature of the risk is obvious. Therefore, Ye Qiuli simply sent his new "Red Rabbit" spaceship back to Earth and asked it to pick up his family members on Earth. With the maximum speed of 50% of the speed of light of the new "Red Rabbit" spacecraft, if it flies non-stop, it will only take at least 8.8 years to reach the Earth from the ancient relic, and if it goes back and forth once, that is, 17 or 18 years, even if there is enough time for reaction and adjustment, it will only take 20 years at most to return to the ancient relic.

In addition to strong enough protection and fast speed, the more critical factor why Ye Qiuli sent the new "Chitu" spacecraft back to Earth to bring his family to his family was that its fuel tank was large enough, the amount of fusion fuel loaded was enough, it could fly at full speed for a long time, and the effective range was long enough, so that there would not be an oolong situation where the spacecraft ran out of fuel halfway through the flight.

In fact, in interstellar travel, in addition to the speed of the spacecraft needs to be fast enough, the spacecraft must carry enough fuel, and even this factor exceeds the speed requirement. Just like flying from Earth to the Ancient Relic Star, even a spacecraft propelled by a nuclear fusion engine would normally consume two million tons of fuel. With so much fuel demand, it is impossible to meet it with ordinary reserve means, and naturally, interstellar voyages can only be an unattainable fantasy, which seems to be close at hand, but it cannot be realized.

The most critical factor why Ye Qiuli was able to fly from the earth to the ancient relict star with ease and ease at all, without worrying about the lack of fuel for the spacecraft, was that he refined a storage bracelet into the fuel tank of the "Red Rabbit" spaceship, so that the fuel storage tank, which looked inconspicuous on the outside, had an internal space that was mysteriously expanded to tens of thousands of cubic meters, which could load all the fuel needed for the whole process at one time. Moreover, after the transformation of the cultivation method, after storing all the huge amount of fuel in the storage space, its weight will be as if it does not exist at all, and it will not increase the weight of the spaceship.

There is no need to calculate carefully, just compare the weight difference between a fully loaded spaceship of two or three million tons and an empty ship of about 10 tons, and you can know how fuel-efficient the spaceship that has been transformed by the cultivator's refining method is. Without the drag of tens of millions of tons of fuel itself, the entire spacecraft has been in an empty state, and the flight speed can naturally be increased to an extremely high level, and the effective range can also be infinitely extended.

In addition to these two reasons, Ye Qiuli sent the new "Red Rabbit" spaceship back to Earth, and he also needed the spacecraft to send back to Earth a batch of cultivation resources and elixirs that he had specially collected and refined, so as to help his family quickly improve their cultivation and prepare for the next long space trip.

Ye Qiuli, who had already experienced it personally, knew very well that the long interstellar journey from the earth to the ancient relic star was not at all as beautiful and romantic as ordinary people imagined, but was full of unspeakable loneliness and boredom, and people who were not strong enough could not bear it at all, and only cultivators with a high cultivation realm could have enough concentration to persevere, and there would be no mental illness.

In the same way, the physical fitness of cultivators far beyond ordinary people can also avoid any changes in them in the vast universe, which is more conducive to dealing with emergencies in interstellar flight and ensuring the safety of flight. If the people of the Ye family on the earth want to fly smoothly in the long sky and successfully reach the ancient relic star, they naturally have to make a breakthrough in cultivation and improvement. And all of that, we could only count on the help of Ye Qiuli's elixir that teleported the past.

While transmitting back a sufficient amount of cultivation resources, Ye Qiuli also needed to bring back to Earth a batch of large-capacity Qiankun bags with a storage space of 1,000 cubic meters that he had specially refined through the "Red Rabbit" spaceship, so as to help his family on Earth facilitate the shipment of the huge amount of logistics materials that must be used in interstellar travel. At the same time, he also hopes that the family members on Earth can bring enough scientific and technological equipment to the Ancient Relic Star to help the Ancient Relic Star develop as soon as possible.

After all, the current level of social development of the ancient relics is basically still in the feudal period, and it is completely incompatible with the incomparably developed modern scientific and technological civilization on the earth, and if you want to improve the scientific and technological level of the ancient relics at the fastest speed, it is definitely impossible to develop it slowly, and the best way is naturally to directly transfer a complete set of the most advanced industrial system from the earth, and use the powerful means of cultivators to help it achieve leapfrog progress.

Ye Qiuli didn't want to take his family members on the earth to the ancient relic, and then repeat the industrial development process of the earth again, and then destroy the natural environment of the ancient relic. However, he is preparing to let the ancient relict star directly enter the era of nuclear fusion energy, skipping the era of chemical energy, in order to protect the hard-won original natural features of this planet.
