Li Yi, who is extremely rational, believes that playing time travel is not as easy and beautiful as described in YY's time travel novel, but should be an extreme risk-taking behavior that will die if it is not done well in many crises, especially when the other side does not know what kind of world it is, and the potential risk of crossing action is greater.

Whether it is an ancient or future world, or another world, Li Yi believes that the natives who travel through the world are by no means NPCs that can be arbitrarily abused by players in online games, at least in terms of IQ and strength, they will never be worse than the traversers, and in terms of environmental adaptation, the traversers are definitely not as good as the natives.

Since the traverser has no advantage, if there is no golden finger, if the necessary preparations are not made in the early stage, it is difficult to stand on the same starting line with the natives, of course, if it is just a rebirth of the crossing, then there will not be much risk, but Li Yi, who has always been objective and rational, does not have this kind of luck psychology at all, and it is obvious that this is a direct physical crossing, not to mention rebirth.

Therefore, as the organizer and planner, Li Yi had already done a lot of preparation before forming this small crossing gang.

The entry of Ladanliang and Xu Wei into the gang is actually a kind of personnel preparation, and Li Yi naturally has some consideration in terms of their personal abilities, personalities, and specialties.

Among the three, Li Yi is good at analysis and research, organization and planning, strategic guidance, objective and rational personality, introverted and low-key, highly educated, believing that knowledge is power, and his disadvantage is that he is a little perfectionist and romantic, and he is a little arrogant or sullen, so he is not so round in terms of dealing with the world, but he is more than enough as the core organizer and behind-the-scenes military advisor of the team.

The second fool is Shanliang, with a height of 168CM and a weight of 62KG, with a strong body and an ordinary appearance. Impulsive, outgoing, active, high-profile, intelligent, quick to respond, high emotional intelligence, good at observing words and feelings, make up for Li Yi's shortcomings in interpersonal communication, the shortcomings are that he likes to speculate, gambles, learns miscellaneously but is not refined, opportunist, money worshipper, and believes that money is power.

Although Shan Liang graduated from a junior college military academy, in fact, he just spent money to buy a diploma, to say that he fights with his bare hands, he is indeed stronger than ordinary people, but his actual military skills are a scum, this is really good at interpersonal contacts, business speculation, not only good at but also like to drill camps, his ordinary and honest appearance largely conceals his true nature, with a certain degree of deception.

As for the three stupid fat man Xu Wei, he is 192CM tall, weighs 132KG, is tall and strong, and he can't talk about fat, but fat is certain, and his appearance is honest and joyful. The character is more passive, generous, lazy, sometimes a little out of tune, a foodie, comparable to gluttony, a typical carnivorous, hedonist, believes that food is power, and at the same time is a violent, only weapons and equipment theory.

This guy is a military fan, don't look at the size needs to be improved, but after all, he was born in a police family, and his father is still in the security system, so his military knowledge and skills are the strongest among the three, and because he likes to eat, he has unique insights into all kinds of food, and his natural cooking skills are comparable to that of a chef.

In addition to ability, what is more important is that Shan Liang and Xu Wei are both Li Yi's juniors, they are both primary school classmates and neighbors, they know each other well and trust each other.

In addition to the personnel convocation, Li Yi also made a lot of preparations and planning.

Materials are the most important thing, no matter what world is opposite, it is always good to be prepared, he doesn't think he has the ability to go from having nothing to a lot of money.

According to the division of labor, Xu Wei was mainly responsible for the purchase of expedition equipment, and finally raised a range of expedition equipment, including bags, backpacks, combat uniforms, combat boots, outdoor glasses, binoculars, sapper shovels, pickaxes, tent sleeping bags, lighters, magnesium sticks, compasses, lunch boxes, water bottles, umbrellas, raincoats, flashlights, headlights, rescue ropes, sabers, electric batons, etc., etc., but unfortunately still did not get a firearm, the only medium-range assault weapon was only a steel crossbow that could be stacked and disassembled.

Shan Liang is responsible for the basic production of living tools and materials, such as various hardware tools, thermometers, hygrometers, radiometers, barometers, fishing rods, compressed food, mineral water, medicines, all kinds of vegetables and grain seeds, and under Xu Wei's strong request, he also bought some oil, salt, sauce, vinegar, spices, cigarettes, etc., and Erguotou also brought two bottles.

Li Yi is also under pressure, he is a mental worker, responsible for the collection and storage of various electronic documents and technical data and various electronic equipment. These include digital cameras, solar chargers, spare power banks, laptops, a rugged mobile phone, a voice recorder, more than a dozen large-capacity hard disks and more than 100 small U disks, all of which add up to 30T, which are all filled with data and pictures and videos related to politics, military, culture, industry, technology, astronomy and geography and various disciplines in ancient and modern China and abroad.

The accumulation of so many supplies was enough to form a small mountain, and the three of them bought six large suitcases and six large backpacks and pounded them for a day before they could barely fit them, and all the seams and corners were stuffed inside.

Due to the special nature of crossing the wormhole, the standard configuration of the three-person crossing is to wear a set of expedition equipment for each person, drag a suitcase for each hand, carry a backpack on the shoulder, and hang another one on the head in front of it, so as to ensure that everything can be worn with the crew.

Under Li Yi's efficient organization, it only took half a month for the three of them to complete the preparation of materials, and in the half month of crossing the wormhole, the situation was quite stable, and the area was only reduced by one-third as expected, close to the size of a double door, and there was obviously a certain amount of time to spare.

In the following time, the three of them built an online chat group, and began to discuss all kinds of matters that may be ignored now after the crossing day and night, which can be regarded as picking up the missing things, and also opened a discussion post on the largest social forum in China, inviting the majority of netizens to participate in brainstorming, of course, the topic of discussion is naturally in the name of YY overhead.

Not to mention, the wisdom of netizens is endless.

Someone suggested that according to Li Yi's current list of materials and technologies, it is absolutely enough to travel to ancient times, which is obviously influenced by the travel text, after all, most of the well-known travel texts are traveled to ancient times, because it is easier for the author to play, but in case of crossing to the other world or the future world, these materials are not enough, and one or two focuses should be grasped in the preparation of software materials.

If you are traveling to another world, in terms of software technical data, you should collect all scientific and technological knowledge in physics and chemistry in a more subdivided way, whether it is basic or cutting-edge, or still in the verification stage, you should collect it.

Because whether it is a magical otherworld, a fairy world, or an overhead otherworld, its world origin should not be too detached from the basic principles and laws of basic physics and basic chemistry, and many phenomena or skills can even be explained by these scientific principles, even if they are violated, they are not afraid, mastering modern physics and chemistry knowledge is equivalent to mastering an independent armed system, creating guns and even nuclear weapons or something, and can still kill the so-called archmage, paladin, and Xiuzhen old monsters in seconds, which is actually the advantage and golden finger of the traverser.

If it is to travel to the future, then most of the hardware and software prepared now will be useless, and the scientific and technological information will inevitably lag far behind the future era.

When encountering this kind of crossing situation, we should do the opposite, that is, prepare a large number of ancient and modern Chinese and foreign art, culture, aesthetics, philosophy, theology, martial arts, archaeology and other humanities materials to bring over, these are the biggest advantages of the traveler, and it may become an existence such as a golden finger.

Because the more developed the era of science and technology, the stronger people's demands for spiritual life and spiritual civilization, the more ancient things will be more popular, just like modern people like to engage in antique collection, what intangible cultural heritage, when the time comes, a bag of Beijing instant noodles may become an antique, and it is not impossible to meet Kaizi, who likes to collect and is rich, to change a starship.

The infinite play of netizens gave Li Yi a lot of meaningful inspiration, and thus added several technical information of hard disks, and the content was more focused on the skills and knowledge that may be used in the other world or the future world, and the classification content was more refined, and the foodie Xu Wei took out some dispensable exploration equipment on this ground, and increased the proportion of food.

After completing these preparations, Li Yi also made several sets of plans for different situations that may be encountered in different worlds, and made Shan Liang and Xu Wei familiar with each other to reach a unified voice.

Half a month passed quickly, and at this time, the area of the wormhole had been reduced to the size of a door, although it seemed that it could be delayed for a few more days, but in order to prevent accidents, the crossing gang led by Li Yi decided to start the journey immediately after making all preparations and raising their spirits.

Before leaving, Li Yi finally instructed: "I'll go first, Xu Fatzi is second, and Shan Liang is last." ”

Seeing that the two of them nodded nervously, and had no objections, Li Yi smiled: "Be quick, don't think about anything after you go in, you'll be there in the blink of an eye, there's nothing to worry about." ”

As he spoke, Li Yi, who was fully armed, raised his feet and walked into the wormhole without looking back, seeing that his figure was not in the wormhole, Xu Wei and Shan Liang couldn't help but glance at each other, and then gritted their teeth, dragging their suitcases one after the other......
