Su Fan didn't notice Dema's eyes, she walked to Allen's bedside, put the syringe on Allen's arm, and then pushed a little bit of penicillin in, too much penicillin will kill people, so Su Fan just injected a little bit, and then put away the syringe and more than half a tube of medicine.

After a few minutes, the infrared radar showed that Allen's body temperature had dropped and his face had returned to normal, and after a while he woke up, first looking around blankly, and then struggling to sit up.

"Linna?" the first thing Alan saw was Su Fan.

"First of all, you are not dead, I am not dead, this is your home. Su Fan knew what Allen was going to say, he was seriously injured and unconscious halfway through, and he didn't wake up until now.

"Uhhh

"Look for yourself..."Su Fan took a step back, revealing the three people behind him, and when Alan saw that the three of them were safe and sound, he was relieved and lay back on the bed, "By the way, that listening device..."

"It's back, but only the four of us are back, and the rest...this thing is because..."

"Alan, you're just right now, let's take a rest first!" Delma interrupted Alma's words and said to his son, although the fever had subsided, but because of the long-term fever, Allen's physical condition was still a little poor, and after hearing his father's words, he nodded.

"Let's go!" Alma pulled a few roommates out of Alan's bedroom, and while Delmar was about to spend a while with her son, the four of them came out first.

Alma led the four of them to his bedroom, and as soon as he entered the bedroom, Su Fan had the idea of fighting the local tyrants and dividing the land, is Nimana a bed? Nimana is a swimming pool in the slightly smaller room next to it, right? I have never seen a swimming pool inlaid with precious stones? Also, what is that shining light? Such a big gem is set in a chandelier, and I am not afraid of falling off and smashing my head back? It is too extravagant! It is worthy of being the duke of the empire!

"Alma, who is that Kane?" Su Fan knew that he seemed to have a feud with that ruthless man, so he had better understand the enemy situation first.

"Kane is my second brother, I and Alan were born to my father's wife, Kane was born to my father's wife in the side room, but since my mother's death, Kane's mother has become more and more arrogant with her father's favor, if it weren't for her lower background, she would even have to peep into the status of the main room, and Kane is also very jealous of the position of the heir, and often blackmails us, this time...forget it..."

The head of the Dread family is now Alma's father, that is, Delmar Dread, his father and grandfather have abdicated and entered the Council of Elders, Delmar has six sons and four daughters so far, Alan is the eldest, Kane is the second, Alma is the third, and the others are still at the level of Lori Shota;In addition, Delma also has four wives, the main room, that is, Alan and Alma's biological mother, has died of illness, and the remaining three are still alive, one of them is very strong, and the other two play Akalin all day long, and the other one is always at a disadvantage although he has the heart to compete for favor, but he is not scheming enough, and he is always at a disadvantage.

"Forget it, let's not talk about that, how did you study that sonar?" asked Su Fan.

"I'll show you there!" Alma got up from her bed.

"Look, where are you going?" Su Fan was very strange, Fear City was an inland city, huh?

"There's a big lake south of Dread City, which has been cordoned off, and sonar is being tested there. Rui Ke explained to Su Fan.

The four of them left the manor of the Dreadful family and came to the suburbs in a magic crystal car, Su Fan had seen a lot of magic crystal cars in school, but she never bought them, because she was very dissatisfied with the style of this shijie's magic crystal car, either a big brick with a small brick on top or a beetle, it was too ugly, the whole Bugatti Wrangler couldn't get it, Willis was always there, right? Now the magic crystal car that several people are sitting on is a big brick with a small brick on top of it...In detail, it is an old-fashioned Santana.

The magic crystal car quickly arrived at the lake, after a lot of checkpoints, the car stopped next to a newly built dock, four people jumped from the car, in this big lake is estimated to be about the same size as Poyang Lake, the depth is nearly more than 100 meters, even Su Fan can also sail freely in it, at this time on the lake, several small destroyers are going back and forth, and on the shore can see some patrols walking by from time to time.

"What are they using as a target?" Su Fan put her hand in the water, and through the sonar, she found that there were things dragging behind those destroyers, which should be the listeners.

"The creation of submarines is not very difficult, they are all made of submarines, but the performance of submarines is far worse than the kind of submarines that attacked us, only one torpedo can be carried, and the diving time is very short. Ruike looked at the destroyers coming and going on the lake and said to Su Fan, and as he was talking, a pipe stretched out from under the lake, and then a cigar-shaped thing floated up, and several people pushed open the hatch and climbed out of it, breathing in a big gulp of air.

The sonar of the listener is completely dependent on experience to distinguish the direction, distance and what the sound source is, and there is not a lot of theoretical knowledge, especially this kind of listener that uses the magic guide jishu, and then the more advanced one is not nothing, nor is it impossible, but whether it is active sonar or passive sonar, only in the electronic age can it be operated by fools, and the sonar of this era Su Fan is reluctant to give, and even if she gives, how to solve the electronic components? She could make a primitive listening device with her bare hands, but a primitive computer couldn't.

"What's the reaction to this thing in your family?" Su Fan looked at Alma next to him.

"Fan Xiang is good, it has been negotiated, your conditions are fully accepted, and we will go back to school in two days. Alma said, "But you've offended Kane...better be careful, she's a little higher than I am, and sometimes things I can't solve, it's a bit of a problem, it's easy to talk about outside, but inside the school..."

"That thing is also a student of the school?" asked Su Fan strangely.

"No, he didn't get in, but he has a very high status in the second generation, and there are many of his younger brothers in the school. ”

"Forget it, let's not talk about this, sonar is this thing...how to say it..."In fact, Su Fan also knows a little about sonar, she completely relies on electronic equipment to complete the detection, just like a woman will give birth to a child, but how the child changes from liquid to solid, then few people know.

After watching the shore for a while, the four of them were about to go back, but just as the four of them were walking towards the magic crystal car, Su Fan suddenly called out to a few roommates: "Prepare to fight, we are targeted!"

As soon as Su Fan's words fell, a whistling sound came, and then in a very short period of time, several shells flew towards several people, and from the whistling sound, it could be heard that the caliber of these shells was no less than 300mm! Su Fan had prepared before, propped up the shield, and then the shells fell to the side of several people, and an explosion occurred, and the violent explosion made her shield crumbling, and after holding on for a while, it shattered.

However, because of the protection of this protective cover, several people only received a little impact, and were not injured, Su Fan turned his head to look, and the attack was indeed launched from several destroyers on the lake, these destroyers were specially modified, and there was a large-caliber main gun inside the hull, but it was perfectly hidden, and if you didn't observe it yourself, you couldn't find it at all!

"Quick, xiangyou run!" Su Fan shouted, and several people couldn't stop the direct hit of the cannonball.

Listening to Su Fan's words, the three of them ran to the right as fast as they could, and when they just ran for dozens of seconds, there was another round of shelling, but this special kind of boat needs to turn the hull when it rocks from side to side, and the speed of the four people is very fast, and the second round of salvo just fell behind the four people, and the air wave blew the four people away.

Huhu ~ Two blue magic arrays appeared behind Su Fan, and then two BrahMos anti-ship missiles flew out of it, and at the same time she took out the laser navigator and aimed at one of them, she did not have a fire control radar when she was in human form, so she could only navigate in this way.

The two BrahMos missiles climbed into the air, and after circling a few times, the radar was turned on, the target was determined, and then they dived to the surface of the lake, flying towards one of the destroyers, Su Fan also counted silently in her heart, counting that when she counted to 28, one of the missiles hit the target, and the small destroyer of only 1,000 tons was blown up by the waist and sank to the bottom of the lake.

This kind of battleship, known as the mosquito ship on the earth, takes 43 seconds to load, after the missile hits the target, Su Fan rushed forward, and after more than ten seconds, there was an explosion in the back, and the air wave blew her out again, she repeated the previous action again, and another destroyer was hit.

After hitting this destroyer, Su Fan did not continue to run, but stood in place, with a green halo, a large black square piece emerged from her body, rotated rapidly, and formed a huge battleship, this battleship appeared on the shore at the time, as a result, the tail rudder and propeller of the battleship were crushed because of its own gravity.

The close defense guns on the battleship began to spin, splashing a large barrage in front of him, this barrage was too dense, and it was targeted, the shells flying towards Su Fan's body were exploded in the dense barrage, those battleships were all conventional battleships and not mechanics, the giant cannon in the body should be a short-barreled cannon, and the speed of the cannonballs was subsonic shells, otherwise there would not be a whistling sound first, when such a large cannonball faced the dense anti-aircraft fire, it could only mean that there was nothing to be done.
