Data has been sent back to indicate that another batch of animals has died. Qiao Hua had no choice but to erase their monitoring records to see how many creatures were left—there weren't many left.

He was ready to overcome difficulties and fight a protracted battle, but he didn't expect the speed of the big waves to be so fast. In such a short period of time, the subjects fell in droves, and the dwarf tyrannosaurus's heart gradually tightened.

If there is no last species left, then all his efforts these days will be in vain. But after thinking about it, it is better to die late than to die early, so he hopes to get the result as soon as possible.

In the end, only nine species of organisms remained alive in the three radioactive areas. After the examination of the iron egg, it was confirmed that the vital signs of these nine creatures were stable, and there was no sign of mutation.

"It's fine."

The dwarf tyrannosaurus let out a long breath in its wide nostrils, glad it hadn't been wiped out.

However, Tie Dan carefully checked the experimental data: "From a regional point of view, these creatures are all active at the edge of the island, a certain distance from the radiation center area, and the impact is relatively small. ”

That is, the experimental results are not convincing.

Qiao Hua waved his front paws: "Then send them to the radiation center area to continue to observe." ”

This has proven to be effective. Within two or three days, five of these creatures were destroyed by humanitarianism.

Another week passed, and the bodies of the three creatures were severely deformed and humanely destroyed.

In the end, there were only ten rat-like animals left, still standing sickly.

According to the real-time images transmitted by the iron egg, the nose of this animal is longer than that of other rodents, conical-shaped, and its ears are like two small blooming flowers; The body is much fatter than the head, and a long tail curls up behind the buttocks.

Qiao Hua called them the last rats. It means "the last remaining mouse".

The last hope of this dwarf tyrannosaurus was pinned on this small creature that looked like a mouse and had the shape of a cat.

It turned out to be a heavy blow to him again.

After a period of time, the fur on the rat's body begins to fall off, the head is swollen and deformed, and fluid leaks out of the narrow nasal passages from time to time.

When several end rats died one after another due to extreme mutations in their bodies, the dwarf tyrannosaurus was completely desperate.

Could it be that there really no living thing in this era can survive under the influence of strong radiation?

"The hosts. There are only two last rats left. Iron Egg reported.

Qiao Hua was too lazy to test the situation of the two last rats. When the first rat died, it meant that the experiment had failed. Indeed, the last rat's physique was able to delay the destructive effect of radiation later, but in the end, it still could not escape the end of death, which did not meet Qiao Hua's expectations.

But before the dwarf tyrannosaurus gave its final command, it glanced at the real-time video from the iron egg.

He was amazed by what he saw.

The last two remaining rats are one large and one small, and the smaller one always habitually follows the big one to feed, and it is easy to guess that they are mother-child relationships.

In fact, Qiao Hua is still very impressed with these two last rats. When the ten last rats were teleported to the center of the radiation, they were compared to the other eight. The fur of the two rats was very gray, and they ate very little food every day, as if they were suffering from a serious illness.

However, it was these two little things that looked the weakest and survived the test of nuclear radiation.

The dwarf tyrannosaurus also carefully noticed that the fur of the two end rats had taken on a healthy reddish-brown color compared to the beginning, and the amount of food they ate increased. And it's become more agile.

"It's not scientific."

Qiao Hua was curious about what caused this, and hurriedly asked Tie Dan to scan the bodies of the two animals in all directions.

It turned out to be. The two rats were in good health and showed no signs of aberration.

According to Qiao Hua's theory, even if there are some differences between individuals of the same species, the underlying genes are the same. It's the same end rat, the same environment, there's no reason why some of them died. The other part is not affected in the slightest.

However, with the analysis of Tiedan's previous monitoring records, Qiao Hua finally figured out the reason.

The reason why the two rats looked weak in the first time was because they were suffering from a condition that causes immunodeficiency. This disease can be inherited, so the little rat cannot escape this fate.

Before being affected by radiation. The destructive effect of this deficiency on their immune system has become apparent. If there is no external interference, the two last rats will die one after another within half a year.

By accident, the high-intensity radiation not only did not damage their bodies, but also repaired the immune tissues at a very rapid rate. Qiao Hua probably couldn't have imagined that the cruel experiment he carried out would save two lives.

The dwarf tyrannosaurus, which had experienced a lot of ups and downs in his mood, was not immediately ecstatic, but thought about it carefully.

Although according to the current situation, there is nothing wrong with the body of the two end rats. But his ultimate goal is to obtain a gene that is not at all afraid of the effects of radiation.

If these two terminal rats were allowed to continue to grow in a highly radiated environment, would they still be so healthy?

Qiao Hua had no choice but to continue to observe for a while.

That evening, Bean Paste laboriously dragged back the carcasses of five long-billed wolves, threw them down, and ran to the river to drink.

What made Qiao Hua find it interesting was that in order to drag the five long-billed wolves back at one time, this guy didn't know where to find a long vine, and simply wrapped several long-billed wolves around it, while he held one end of the vine in his mouth and pulled them back with brute force all his body.

"Whew-"

The bean paste let out a long howl, and the thick blades of grass on a large tree shook, and then the round body of the kernel slid down the trunk.

The dwarf tyrannosaurus also shamelessly joined in sharing the food. For the last few days, this guy has just been crouching around studying Gliese's bizarre technology: the principle of proton impact, which is more robust than a laser cannon or a nanonet, and the working conditions of the matrix energy beam...... Although he was physically tired, he didn't have any experience.

The life pattern of the pit has always been very stable: eat and sleep, sleep and eat...... Cycle.

In this case, the bean paste had to act as the nanny of the two living treasures, one big and one small. Fortunately, the body of this dog and bear has been strengthened by various powers, and it is still more than enough to deal with most animals.

After simply eating a few bites of the meat of the long-mouthed wolf, Qiao Hua felt bored. The days when you don't have to hunt seem to be very comfortable, but in fact it is a kind of torment - just like a military general who is attacking a city, it is fatal to have to be a literary and artistic young man in a funny way.

After a brief movement of its muscles, the dwarf tyrannosaurus sprang along the only path in the valley. (To be continued.) )
