In the ecological park for a month, Song Zihang found two more prominent problems, the first is that these dinosaurs seem to have problems with growth, and there has been no major breakthrough in volume, and the largest diplodocus is currently dangling at this length of seven or eight meters, which makes Song Zihang feel strange if it doesn't grow big.

The second is that these dinosaurs are very unenergetic, and they like to run to a sunny place to lie down, and they lie down all day, motionless, which makes Song Zihang full of distress, can these dinosaurs become sick?

Song Zihang was unusually puzzled, but after many investigations, careful comparisons, and finally consulted a large number of materials, he finally determined the problem, and the key to the problem is also very simple, mainly because of the external environment.

And the external environment where is not suitable for the growth of these dinosaurs? Song Zihang thought about it and summed it up, and finally determined two aspects, the first oxygen content!

You must know that most of these dinosaurs cloned by Song Zihang are dinosaurs from the Jurassic period 65 million years ago, and the Jurassic is a well-known strong oxygen environment, and the oxygen content in the air is about 21 percent, and the oxygen content in the air during the Jurassic period can reach 30 percent, don't underestimate these oxygen content.

You must know that only when the oxygen content is high enough, the speed of blood transportation of nutrients is fast enough, and the nutrient supply can grow up, just like the early Jurassic, the era of giant insects, when the oxygen content in the air reached 35 percent, so a centipede can only reach five meters away, and a dragonfly can grow to three or four meters long.

This is the important role of oxygen, now these dinosaurs are because of insufficient oxygen, so the body has stopped growing, which is the same as our human malnutrition, human malnourished children will become thin and short, and dinosaurs are also the same reason, insufficient oxygen will cause them to not transport nutrients in place, and then do not grow big.

Song Zihang figured out this, and knew that he had to solve the problem of oxygen content in the air first, and the solution to this problem, Song Zihang thought of a high-power oxygen supply equipment introduced in Wang Xingren Technology!

This equipment has a very high work efficiency, can produce a large amount of oxygen through a series of biochemical reactions, and finally can produce a large amount of oxygen for human use, this technology has been used by the Wang Xingren in the spacecraft feeding system, you must know that the Wang Xingren's spacecraft can ensure sufficient oxygen supply even if it travels in the universe for several years, or even decades, which is very revealing.

Song Zihang thought of this, and immediately began to prepare various equipment, and then carried out the construction of oxygen supply machines, it took about a month, ten huge oxygen machines were in place, and then under the full operation of the oxygen machines, a large amount of oxygen was directly provided to the ecological park, and the oxygen content in the ecological park was increased to several levels, and finally stabilized above the constant value of 30 percent!

This time the dinosaur babies were happy, after having enough oxygen, these dinosaur babies began to lie and grow up, half a month, the largest Diplodocus has broken through fifteen meters, at this rate, in two or three months this Diplodocus can become an adult, can grow to twenty or thirty meters.

That's a real behemoth, a real invincible creature!

Song Zihang said that he was very happy about this, but just a little excited, Song Zihang's brows furrowed again, because Song Zihang found that his second problem was still not solved, which was very troublesome!

The second problem is that these dinosaurs are very inactive and even reluctant to move, what is the problem?

Song Zihang thought about this problem for a long time, and finally basically confirmed that the reason why these dinosaurs were reluctant to move was completely because the temperature of this ecological park was too low, you must know that these dinosaurs lived in the Jurassic era, and the temperature was forty or fifty degrees up, and this temperature is difficult to reach on the earth now, but this is not impossible to overcome, such as artificial sun.

Song Zihang is preparing to create a second sun in his ecological park, the purpose is very simple, that is, to shine on the entire ecological park, warm up the ecological park, and help the dinosaurs in the ecological park solve the problem of severe cold.

The artificial sun is a scientific research problem that human beings have been researching, the purpose is that after the sun is extinguished, human beings can continue to live in this land, how to create a super heating sphere that can continue to provide light and heat for human beings is a heavy weight

However, this research is so difficult that human beings even gave up this idea for a while, and even proposed that they could install a planetary engine on the earth, push the earth to run, retreat the earth into another star system, and rub the light of another star, but no one thought that after the sun was extinguished, human beings could raise an artificial sun to shine on the earth and let the earth shine again.

No one thought of it, or rather, it wasn't that everyone didn't think about it, but everyone didn't want to think about it, because this idea was too difficult to implement, even harder than pushing a planet.

There's no way, but this technology has been realized on the planet of the Wangxingren, in fact, there is only one technical difficulty, and that is controllable nuclear technology.

The reason why the sun has been shining and heating has not dried up, is simple, that is, the sun is undergoing nuclear fusion every minute and every second, so the energy produced is enough to support the sun to shine and heat to this day.

Therefore, as long as you can master the controllable nuclear fusion technology proficiently, then the artificial sun is not a problem, and the controllable nuclear fusion technology is currently impossible for human beings to master, but Song Zihang is not an ordinary person, this is Da Luo Jinxian, so the problems that human beings cannot solve with science and technology at present are not a problem here in Song Zihang.

So Song Zihang was ready to challenge the difficulty of controllable nuclear fusion, so Song Zihang began to research, this research was another month, and a month later Song Zihang finally came up with a round ball, which was filled with uranium materials used in nuclear fusion, which were originally prohibited by the state, but Song Zihang cooperated with the state, so the state approved a mine to Song Zihang.

Song Zihang dug up all the uranium from this mine and filled it into this huge ball, which was the artificial sun designed by Song Zihang.

Song Zihang prepared for a long time, followed by the help of the instrument, sent the artificial sun into the sky, watched the artificial sun fly into the sky, and shine, and suddenly raised the temperature of the entire ecological park, Song Zihang finally let go, this hard work has been almost half a year, spent countless funds, and the super dinosaur park built has finally been completed, really, it is not easy!
