Lin Jia is a well-known agriculturist and an excellent geologist, and his knowledge in this area is far stronger than that of Su Yichen, who specializes in applied physics, mathematics and electronics, and even the highly respected Professor Wan Changchun is far less professional than Lin Jia in this area. Therefore, when they saw these words written by Lin Jia, their expressions became especially serious at the same time, as for Hu Zhijun, he was just curious about the cause of Lin Jia's death and wanted to find the answer to Lin Jia's death from this notebook.

“…… The discovery of giant ferns, including some large ferns, surprised me, and then my eyes were deeply attracted by the two huge almost impossible giant trees, as a scientific researcher with professional knowledge, I can hardly describe the shock in my heart, as far as I know, there is absolutely no such giant tree in the world, because although the growth of plants is theoretically unlimited, under the influence of air, soil, nutrients and other factors, Plants still have many limitations in reality.

There are many tall plants in the world, and some plants, including the giant sequoia found in the United States, although it has exceeded the diameter and height of conventional plants, can be explained by botany majors, it is still within a certain biological reasonable range, but this value is close to the limit.

The two giant trees in front of me are far beyond the limit in terms of diameter and height, as I have said before, the growth of plants in nature is affected by many factors, the simplest point, that is, the earth's gravity will become the biggest factor that inhibits the unlimited growth of plants, because when a tree grows every inch up, the nutrients and water absorbed from the roots need to be transmitted to the canopy and treetops through the internal veins of the tree. At the same time, the light and action of the leaves in the sunlight also need to mediate the nutrients of the whole tree, and the higher the tree grows, the longer the distance of this transmission will be, and thus the more difficult it will be.

Moreover, the height of a tree also represents the development of its root system and the depth of its underground level, which can be judged according to the basic knowledge of botany. And when I took a closer look at these two trees, I came to the conclusion that this is an impossible miracle. Because I could scarcely believe my eyes when my preliminary calculations were placed in front of me, and if they were true, nothing else would have been said of it, but the development of the internal veins of the tree and the tremendous pressure of transporting nutrients, including water, were enough to cause the trunk of the entire tree to burst from the inside like a steam pot that could not withstand the pressure.

However, the facts are before my eyes, which makes the calculation of a qiē a meaningless thing. And I searched through all the knowledge about plants in my head, and I still couldn't tell what these two trees were.

Due to the lack of necessary instruments and equipment around me, although I was far more curious about these two trees than about the giant ferns, I was unable to study them further. Initially, I tried to find some answers by cutting open the bark and looking inside the tree with the iron tools I was carrying. Disappointingly, the trunks and main branches of these two trees were so strong that the iron tools failed to cut through their surfaces, which made me think of the iron birch, which is known for its hardness, or is stronger than it.

This was something I had anticipated in advance, because without such a hard characteristic, it would not have been able to support the developed veins and pressures it generated. Although I feel a little regretful in my heart, it is also a discovery that confirms this. Giving up on the futile study of the two giant trees, I set my sights on the grassland, and at this moment I suddenly noticed that the grass on the ground seemed to be something strange. I soon confirmed my judgment that the ordinary-looking grasses, including some of the strange flowers that bloomed in the grasslands, were herbs I had never seen before, and there was no mention of them from the information I knew. ”

When they saw this, Su Yichen and Wan Changchun silently exchanged glances at the same time, the situation in the grassland was what they ignored, although they and Lin Jia's scientific research direction was different, as a more professional Lin Jia, it was normal to be able to judge this, but just from this point of view, it showed that Lin Jia was serious and meticulous in scientific research, and they couldn't help but sigh in their hearts.

Lin Jia wrote three pages of text, which detailed the preliminary research and judgment he made after discovering the surrounding anomaly, and at the same time, Lin Jia also wrote in the later pages that he observed that there were no signs of any animals in this place except for plants and him alone, and this strange phenomenon also puzzled him.

After about two or three hours of preliminary investigation, Lin Jia decided to search the place. Before searching, he also made some preparations, collected some edible ferns and some fruits on the other side of the forest, and even collected a few red fruits growing on the two giant trees, which were not for food, but intended for research.

After doing this, he filled the kettle by the lake, and after choosing a direction, Lin Jia set out to explore the surroundings, and this time the exploration lasted for four days.

“…… For four days I walked through almost identical steppes and almost identical forests, all of which seemed to be planted and arranged in this place according to a strange pattern, which struck me as strange. It's also strange that there are two giant trees, and the other qiē in the whole world 'let's call it the world' are duplicates, but only these two giant trees are separate zài.

At first, I thought that there is no night in this world, because the sun in the sky is almost always there, but I was wrong, I later found out that it also has a dark night, but the coming of night is different from our common sunset, the sun does not rise in the east and sets in the west, but the sun hanging in the sky gradually dims and gradually forms a bright moonlight. It was so strange that it looked like the sun had turned into the moon in the blink of an eye, hanging high in the sky like the bright moon of the fifteenth. As for the stars in the night sky, there are also in the dark night, but the stars look so different that I can't find the familiar stars at all, not even the most recognizable Big Dipper.

There is also a difference in the time ratio between day and night, the night seems a little short, according to my watch, the night here only lasts about five hours, and the rest of the time is all day. But fortunately, the rotation of night and day is still 24 hours, it took four days, I walked forward nearly 200 kilometers, and finally I didn't see it, but I saw a vast ocean, but like the quiet forests and grasslands, this ocean is also so quiet, even quiet and a little scary.

I didn't have a boat to go out to sea, and I didn't have any tools to build a boat, so I couldn't explore what was on the other side of the ocean. I looked at the sea along the coastline and thought about it for a long time, and finally decided to choose another direction to go forward, hoping to find a different place to ....... ”

The part of June 18th was over, and when they turned the last record page of the day, Su Yichen and Wan Changchun looked a little solemn, Lin Jia's exploration seemed to have no results, and the end of the grassland was actually a quiet ocean, which also surprised them a little.

For the next ten days, from June 19 to June 29, the records in the notebook were all records of Lin Jia's continued search to the sky along the coastline, and the contents of the records were basically the same, from which it can be seen that Lin Jia did not find anything different, as if the qiē area he passed through was similar and similar.

It wasn't until June 30 that Lin Jia wrote in his record that he walked around the coastline and finally walked back to the beach where he had started, and saw again the mark he had made on a rock by the beach. At this moment, Lin Jia can be sure that the place where he is actually a large island isolated in the ocean, and according to his estimates, the land area of this large island is about 20,000 square kilometers, which is almost two-thirds of Hainan Island.
