Lin Jia is a famous agriculturalist and an excellent geologist. His knowledge in this area is much stronger than Su Yichen, who focuses on applied physics, mathematics and electronics. Even Professor Wan Changchun, who is highly respected, is far less professional than Lin Jia in this area. Therefore, when they saw these words written by Lin Jia, they also became particularly serious. 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. Then my eyes were deeply attracted by the two huge, almost impossible giant trees. As a scientific researcher with professional knowledge, I can't describe my inner shock. As far as I know, it is absolutely impossible for such giant trees to exist in the world, because although the growth of plants is theoretically not limited, under the influence of various factors such as air, soil, nutrition, etc., plants still have many limitations in reality.

There are many tall plants in the world. Some plants, including the giant sequoia found in the United States, have exceeded the diameter and height of conventional plants, and can be explained by the botany major, it is still within a certain bioreasonable range, but this value is almost approaching its limit.

The two giant trees in front of me have far exceeded the limit in terms of diameter and height. As I said before, the growth of plants in nature is affected by many factors. The simplest point is that the gravity of the earth will become the biggest factor in inhibiting the unlimited growth of plants, because whenever a tree grows up one inch, the nutrients and water absorbed from the roots need to be transmitted to the crown and treetops through the veins inside the tree. At the same time, the light and action of leaves in the sun also requires nutritional mediation of various parts of the entire tree. When the tree grows higher, the longer the distance of this transmission will be, and thus the more difficult it will be. If expressed in mathematical terms, this factor will grow geometrically, thus limiting its growth.

What's more, the height of a tree also represents the development of its roots and the depth of the underground, which can be judged based on basic knowledge of botany. When I carefully examined these two trees, I concluded that this was a miracle that was simply impossible. Because when the data I calculated in front of me, I could hardly believe my eyes. If these data were true, it would be more than anything else. Just the development of the internal veins of the tree and the huge pressure of transporting nutrients and water were enough to make the trunk of the whole tree burst from the inside like a steam pan that could not withstand pressure.

However, the facts are in front of me, which makes all the calculation data meaningless. Moreover, after carefully searching for all the knowledge about plants in my mind, I still cannot judge what kind of trees these two trees are.

Due to the lack of necessary instruments and equipment around me, although I was far more curious about these two trees than those giant ferns, I could not conduct further in-depth research on them. Initially, I tried to use the iron tools I carried to cut the bark and look at its interior to find some answers. But disappointingly, the trunks and main branches of these two trees were extremely strong, and the iron tools could not cut its surface at all. This reminded me of the iron birch, which is known for its hardness, or its hardness is stronger than that of the iron birch.

Although this was something I had expected in advance, because without such hard features, it would not support its internal developmental veins and the pressure it generated. Although I felt a little regretful, it was a discovery that it was a discovery. I gave up on continuing the futile research of these two giant trees, and I turned my attention to the grassland. At this moment, I suddenly found that the grass on the ground seemed a little strange. Soon I confirmed my judgment that those grasses that looked ordinary, including some strange flowers blooming in the grassland, were all herbs that I had never seen before, and there was no record of them in all the information I knew."

When seeing this, Su Yichen and Wan Changchun exchanged glances silently at the same time. The situation on the grassland was something they ignored. Although they were different from Lin Jia's scientific research direction, it was normal for Lin Jia, who was more professional, to judge this point. But from this point alone, Lin Jia's seriousness and meticulousness in scientific research work, which made them feel moved.

The day was relatively long, and Lin Jia wrote three pages of text, which detailed the preliminary research and judgment he made after discovering the abnormalities around him. At the same time, in the later chapter, Lin Jia also wrote that he had observed that there was no sign of animals in this place except plants and him alone. This strange phenomenon also puzzled him.

In addition to the preliminary investigation for about two or three hours, Lin Jia decided to search for this place. Before the search, he also made some preparations and collected some edible ferns and some fruits in the forest. Even Lin Jia also collected a few red fruits grown on the two giant trees. This was not for consumption, but was intended for research.

After doing all this, he filled the kettle by the lake, selected a direction and set out to explore the surroundings. This exploration lasted for four days.

"...In four days, I walked through almost identical grasslands, and passed almost the same forests. They seemed to be planted and arranged in this place according to a strange rule, which made me feel very strange. Another thing is that there are two giant trees. The whole world is called the world. Everything else in the other way is repeated, but only these two giant trees exist separately.

At first, I thought there was no night in this world because the sun in the sky almost always existed, but I was wrong. Later I found that it also had nights, but the arrival of the night was different from the sunrise and sunset we often had. The sun did not rise from the east and set in the west, but the sun hanging in the sky gradually dimmed and gradually formed a bright moonlight. This was simply too strange. It looked like the sun turned into a moon in the blink of an eye, hanging high in the sky like a bright moon on the fifteenth. As for the stars in the night sky, there were also in the night, but the starry sky looked very different. I couldn't find where the familiar stars were, and even the easiest Big Dipper could not find its location.

The ratio of day and night is also different. The night seems a bit short. According to my watch, the night here only lasts for about five hours, and the remaining time is all day. Fortunately, the rotation between night and day is still 24 hours. After four days, I walked forward for nearly 200 kilometers. I didn’t see the end at the end, but I saw a vast ocean, but like the quiet forest and grassland, this ocean is also so quiet, even a bit scary.

Because there were no ships to go out to sea, I didn’t have any tools to build ships, so I couldn’t explore what was on the other side of the ocean. I looked at the sea and thought for a long time along the coastline, and finally decided to choose another direction to go forward, hoping to find a different place….”

The June 18th part ended. When they turned over 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. Moreover, the end of the grassland was actually a quiet ocean, which surprised them a little.

In the next ten days from June 19 to June 29, the notebook records were records of Lin Jia continuing to search the sky along the coastline. The contents of the records were basically the same. From this, it can be seen that Lin Jia did not find any different places, as if all the areas he passed by were similar.

Until June 30, Lin Jia wrote in the record that he walked around the coastline and finally returned to the beach where he had set out, and saw the mark he made on a rock by the beach again. At this moment, Lin Jia was able to confirm that the place where he was actually a large island alone in the ocean. At the same time, according to his estimate, the land area of ​​this large island is about 20,000 square kilometers, which is almost two-thirds of that of Hainan Island.
