Time passed again, and Tian Daoling copied all the materials that could be copied into the USB flash drive, and the USB flash drive materials in his storage space could be said to be worth a thousand gold, and any piece could make any country in the real world crazy.

Although the time gap between the Elysian Space world and the real world is only more than a hundred years, the degree of scientific and technological development of the two worlds is not the same, when obtaining scientific and technological information, Tian Daoling has roughly checked the historical information of Elysium, and he found that the scientific and technological development of the two worlds in the same period is not at the same level at all.

When the real world just began the first industrial revolution in the eighteenth century, the Elysium world had already experienced the second industrial revolution with the invention and application of electric power technology, and when the real world had just begun to enter the second industrial revolution, the Elysium world began the third industrial revolution with the invention and application of atomic energy, electronic computers and space technology as the main goal. Just the three industrial revolutions have consumed the earth's resources in the Elysium world, which is why this world is so barren just over a hundred years longer than the real world.

During this time, in addition to obtaining scientific and technological information and learning about the history of Elysium, Tian Daoling also directly received some scientific and technological products into the storage space, medical machines, robots and other various things, and he regretted why he didn't spend soul points to expand his storage space when he entered this world, so that he couldn't store a lot of things, Now he was still thinking about whether he should leave the Elysium World and expand the capacity of the storage space to re-enter the Elysium World to collect everything.

When the idea popped up. Tian Dao Ling decided to give it a try, anyway, everything that should be collected has already been collected. Continuing to stay in this world was just a waste of his soul points, so he directly chose to leave the Elysium World and go back to the Walking Dead World.

Tian Dao Ling, who returned to the world of the walking dead, immediately went to the secret laboratory. He handed over all the USB flash drives to the person in charge of the research institute, and asked them to stop other work at hand and start researching the technology of Elysium, mainly in medical treatment, machines and energy, etc., as for other things, I will not study them first, because the technology is hundreds of years apart, and it is impossible to study anything useful without spending a lot of time, so he asked the people in the research room to put the things studied in the simplest aspects.

The world of the walking dead is his foundation, so he must vigorously develop this world. Let the world really become your own hole card.

When he handed over all the information to the research room and left some arrangements, Tian Dao Ling began to contact the exchange system, and found that it was not necessary to spend a lot of soul points to enter the world that he had entered with soul points again, but only to spend the soul points consumed every day, seeing this situation, Tian Dao Ling directly spent 100,000 soul points This huge amount of money to expand the capacity of the storage space by 1,000 cubic meters, is very willing.

The more than 200,000 soul points he had left because of entering the [Super Runaway] World and the [Elysian Space] World were reduced by half again, leaving more than 100,000, but Tian Dao Ling didn't feel any pain in this regard. Because it's totally worth it, expanding his storage space allows him to store a lot of supplies and take valuable things from various worlds.

After the manager can be in the [Elysium] world, many things have also appeared on the exchange system, such as medical machines. Robots, Gauss rifles, and other things are available, but the exchange price for everything is not low. Exchanging a defensive robot in Elysium for 100 soul points is expensive. The price of the medical machine is even more exaggerated, requiring 1,000 soul points. It's about the same as a pistol with unlimited bullets.

However, it is also because these things exchanged for the original sin paradise are more powerful than those in the Elysium world, if the things in the Elysium are an ordinary car, then the things exchanged for from the original sin paradise are top-level sports cars, and they are not of the same level at all.

Just like the medical machine, the medical machine exchanged for the original sin paradise does not need to be like the medical machine in Elysium to treat new diseases, and needs people to input the treatment method of the disease in the medical machine, but can rely on the medical machine to analyze and treat the new disease method through the disease data stored by itself, which is very intelligent, and in terms of energy, it directly uses nuclear energy, without connecting to an additional power supply.

Robots are also more powerful than those in Elysium, the metal used to make robots is the hardest alloy in Elysium, not those ordinary metals, each robot is equipped with a Gauss rifle as standard, and a robot can deal with more than ten robots of the same model in Elysium, which is very powerful.

In addition to these two things, there are a lot of things that can be exchanged, and many things have upgraded versions, such as machines with unlimited energy or flying machines, etc., but no matter how powerful the exchange items are, Tian Dao Ling will not exchange them, rather than spending soul points to exchange these things, it is better to directly spend soul points to enter the Elysium world and use storage space to scavenge, for him at this stage, he doesn't need these things yet, as long as the most ordinary version.

After expanding the storage space, Tian Dao Ling entered the Elysium World several times, obtaining various resources from the Elysium World, especially robots from all sides, so back and forth, it directly cost Tian Dao Ling a full 5,000 soul points, in addition, Tian Dao Ling also spent soul points to exchange some Elysium scientists to the Walking Dead World to help the people in the research room speed up the research of Elysium World technology.

After leaving the Elysium for the fiftieth time, Tian Dao Ling no longer entered, although it only took him three days of rest to go back and forth, but the time he really experienced was fifty days, this was because when he entered the Elysium World, the time in the outside world was suspended, otherwise his rest time would have been spent long ago.

Fifty days of non-stop going back and forth between the Walking Dead World and the Elysium World made him very tired, so he planned to rest for a day or two to relax and relax, and his spirit was not so tense.
