The new signal source device is very tiny and is tied around the bat's neck with a special metal wire. It is covered by thick hair and cannot be seen at all.
"But the northeast coast is far away from here. If we follow the usual rules, even if there is a signal transceiver device, it will be difficult for the base to receive signal feedback, right?"
Li Changtian looked at Su Mi with a smile and said, "It's easy to understand, and a child can be taught. However, in the past, it was true that if the signal source was too far away, it would be difficult to receive the signal.
But your group of mutant bats is extraordinary. Their sound waves can amplify the signal source I set on them by more than a hundred times, and can even block other signal interference. Moreover, I have made some upgrades to the signal source this time, which can help me detect the surrounding magnetic field, sound waves, sonar and other types of signals. Take them there, and I can use them to quickly collect environmental and biological information near the archipelago. "
"But in the past, if you were too far away, the signal would be interfered by various electromagnetic waves. Even if the signal is amplified, the interference will still exist, right?"
"Girl, so you mutant bats are powerful. Although electromagnetic waves can interfere with signals, I have done experiments and found that the signal source amplified by the mutated bats' sound waves will receive extremely slight electromagnetic wave interference. I estimate that from It shouldn’t be a problem from here to the northeastern coast.”
Li Changtian paused, "The only problem is the fog on the archipelago you mentioned. So this time I want you to take these mutated bat groups and try it. If it has any impact, I can make some changes. But I guess , high probability, not a big problem.”
Su Mi took back all the bats that were given to Li Changtian, and suddenly asked Li Changtian to detect the signal source on the bats.
The instrument was turned on, and a piece of snowflakes appeared on it.
"Huh? It's strange. There is obviously a signal, but the signal has been unstable and no information and data can be displayed."
Su Mi looked at the snowy screen and breathed a sigh of relief. It's fine if it can't be detected.
In the past few days, she went to the mining area every day to collect some large and high-quality rough stones into the space. Jiu will follow her to take a look at the black egg every day.
Before leaving the base to go to the northeastern coast, Su Mi went to Jiangnan City again to check the changes in the flamingo eggs and mutated sycamore trees.
Fortunately, the mutated sycamore tree absorbed the flame energy for a period of time at the crater. Not only did it fully come back to life, but even the firebird eggs returned to their original vitality.
Although Jiangnan City was flooded by stagnant water, in such a short period of time, the water quality here became extremely clear, and the water body was not as hot as before. Su Mi jumped off the giant python and felt very comfortable wrapped in the warm water.
"Isn't this a proper hot spring?"
This area is full of fault volcanoes, although for some reason they have not erupted again, and the water has accumulated deep due to heavy rains. Now not only are some aquatic plants growing under the water, but there are actually some small schools of fish starting to shuttle around the rock formations in the volcano.
"There is also a warm pool on the mountain behind our tribe. My eldest brother and my twelfth brother and I often go there to take a bath. My mother said that the pool can strengthen our health."
Su Mi didn't feel anything after soaking in the water for a while, but she did catch a lot of small fish that were close to her body.
The scales on the bodies of the small fish are all shiny and beautiful. But they have almost no meat except for fish scales and bones. A fish whose body is as hard as metal is indeed a strange species of fish.
Seeing that the mutated sycamore tree and firebird eggs were recovering well, Su Mi no longer wanted to take them back to the space.
Qin Hao had already entered the Space Mountains area from his Space Jade, and told Su Mi that they had arrived at the northeastern coastal area. So Su Mi took Jiubian directly to the northeastern coast.
Mountains stand tall here, and the sandy beaches of the sea have disappeared.
Sihui Base can be directly seen from where they are, but the last time she came here, there was only one mountain peak here.
There must be less than three months between them. Why has the sand here turned into a mountain peak?
Su Mi told Qin Hao, Lu Yishan and others about this.
"Girl, there are very active geological manifestations in this area. This mountain peak should have appeared recently. I have checked the address representation and nearby geographical location of this area. I am afraid that in the future, there will be a sandy area here, including the south The base and the water accumulation area in the west will gradually turn into mountains."
Everyone climbed to the highest mountain to look out to the sea.
Lu Yishan and others took the telescope and saw the fog on the sea in the distance.
"Team Qin, Mr. Lu, how do we enter the archipelago? The fog there is too thick, and our detection equipment has failed."
Su Mi released a few mutant bats in the space in the mountains, and released the rest after entering the archipelago.
She pointed to the location of the fog and said: "Let's all stay where we are and have a rest and have something to eat. The fog over there is the location of the archipelago. Seagulls often appear. Let's wait for the seagulls to appear before setting off."
After Su Mi said this, Qin Hao took her to the water-filled shoal not far to the west.
Their ship was parked there. The terrain along the northeastern coast is quite high and the accumulated water cannot flow here, so they can only abandon the ship and go into the mountains.
But so many people wanted to go to the islands, and it was impossible to swim there like her. Moreover, there is a long distance between the coast and the center of the island, and the sea water there has long been seriously polluted.
Most of the marine creatures inside had memory mutations before the apocalypse, and they became even more mutated after the apocalypse. Creatures that have mutated many times are extremely aggressive and dangerous.
The great white shark that attacked her last time is a good example.
There were only a hundred of them, not enough for the great white shark to swallow in a few mouthfuls.
It is safer to use ships and vehicles.
When Su Mi saw the ship, she suddenly had a headache.
Because this was not the big ship she imagined, but a very thick hull made of wood and metal. It had sails and oars, but it was driven by a manual chain.
The principle of this kind of boating is similar to the pedal boat that cost fifteen yuan a time at the park lake when I was a child, except that the boats assembled by the soldiers are more maneuverable and advanced. And the organization is more sophisticated, and it can also be rowed manually with paddles.
After seeing Su Mi's confusion, Qin Hao explained: "This is already the most sophisticated ship that the soldiers can make in a short time. The base does not have much diesel and gasoline now, and if it is to be made into an oil-powered ship, The class, engine, etc. all need to be remade, which takes too long, is also very heavy, and is not cost-effective.”
Su Mi thought about it, it was already very difficult to build such a big ship.
"The creatures in the sea are very dangerous, this ship."
"Don't worry, the propellers and maneuvering devices at the bottom are made of special metal materials, and the bottom shell can withstand the strongest impact of the Big Mac."
Su Mi was startled, "Then I'll be relieved." When she went to sea, she would put Thousand Hands into the sea to be on guard. Even if something approached, she could be prepared in advance.
