"What, what attachment point?" The ghoul was a little confused, he didn't know anything about the high-tech stuff of the four-legged snake, in short, he understood that the attachment point that the four-legged snake was talking about must be a very important thing, otherwise the four-legged snake wouldn't have that expression!!

"The gravity ball needs an attachment point, the best choice is a rock that contains a little iron, generally speaking, the rocks in the sea will contain a little iron, not only the rocks in the sea, but also the ordinary stones also contain some iron more or less, and my gravity ball must have iron to maximize his gravity!!" The four-legged snake did not give a detailed introduction, neither Chu Yan nor the ghoul knew about this thing, of course, if it was replaced by old iron, it would be another matter!!

"You're saying that the stones here don't have the depth to match?" Chu Yan probably heard the four-legged snake's concern, and the four-legged snake nodded and responded to Chu Yan's rhetorical question. [ Point e ]

"What's the situation? Why hasn't it been done yet??" Black Butterfly, Praying Mantis and Otter have successfully reached the summit, and temporarily hidden, as time passes minute by minute, Chu Yan and the others still have no progress, which makes Black Butterfly very worried, because in less than five minutes, the next wave of sea patrol boats will turn around, and the three or two motorboats are simply nothing to hide, and there is no way to hide!!

"It's going to be good right away!!" Chu Yan looked at the four-legged snake, his anxiety was understandable, but Chu Yan would always have some way to solve these unexpected troubles!!

"Four-legged snake! ghoul, tie these three or two motorboats together with ropes, quick!!" Chu Yan had already opened his mechanical hard bow as he spoke, and took out an ordinary alloy arrow from the quiver behind him, and above the tail of the alloy arrow, there was a steel wire that was like a hair, this kind of steel wire similar to the fishing line was made by Lao Tiehua with a lot of money, and the toughness and strength were super first-class. 【--*Yuu】

The three motorboats were quickly tied together with the joint cooperation of the ghoul and the four-legged snake, the four-legged snake held the rope and waited for Chu Yan's next order, at this moment, whoever can solve the trouble in front of them will become the temporary commander, this is what they negotiated after chatting and drinking at the assembly base!!

"Dodge!!" The mechanical hard bow opened and aimed at the bottom of the water, at the same time, Chu Yan's arm suddenly bulged muscles, and the mechanical hard bow instantly pulled to the full moon, and then the alloy arrow shot directly into the water in the bowstring tremble, and after a second, the alloy arrow stopped advancing, Chu Yan's hard bow lifted up, and the steel wire was connected to the bow body of the mechanical hard bow, although the arrow was shot into the bottom of the water, the steel wire was always under Chu Yan's control!!

"Four-legged snake, tie the rope in a knot, and then thread the wire into it, ghoul, prepare to dive, let's pull these three motorboats into the bottom together!!Hurry!!" After Chu Yan finished ordering this, the four-legged snake quickly tied a knot in the rope, and then passed the wire in Chu Yan's hand through the knot, and the three of them glanced at each other, and suddenly plunged into the water together!!

The three figures exerted their strength together, and the gravity ball of the four-legged snake started to increase the weight of nearly 100 catties out of thin air, and the three motorboats slowly sank into the water!!

"Whoa!!!" In about a minute, Chu Yan's heads came up from the bottom of the water, and the motorboat had been pulled into the bottom of the water, and fixed at a depth of at least three meters below the water surface with a steel wire, if you don't carefully observe the water surface, you won't find the existence of the motorboat, even if the water surface is very clear, because the water flow here is not stable, and there are many waves, although it is not big, but it is enough to affect the intuitiveness and depth of the line of sight!!

"Quick!!" As soon as the four-legged snake came out of the water, it tried to pull the rope and climb up, while at the same time, two searchlights-like lights turned from a distance!!

"Blue wolf, the patrol boat is coming! Hurry up!!" Black Butterfly also found out about this situation, the speed of the three people was completely fine, but because of the waste of a lot of effort under the water when dealing with the motorboat just now, and the breathing has not been adjusted just after coming out of the water, so, if you really have to hurry, I am afraid that there will be an accident that should not be had!!

"It's too late!! four-legged snake!ghoul!!Quickly adjust your breathing and prepare to dive into the water, black butterfly, you three hurry up and take back the rope temporarily, hurry!!" With Chu Yan's order, Black Butterfly immediately understood what Chu Yan wanted to do, and the ghoul and four-legged snake also understood that Chu Yan's choice at this moment was absolutely correct, I wish everything went well!!

The three ropes were quickly put away, and the jungle belt fell into silence again, while Chu Yan, the four-legged snake and the ghoul only showed one head in the water, quickly adjusting their breathing, and when the light of the spotlight swept across the water where the three of them were, the three of them took a deep breath at the same time, and then dived underwater!!

The speed of the patrol speedboat is very fast, and the splash on the water surface is also very large, and the two spotlights shine back and forth on the hiding place of Chu Yan and the others several times, and then they change the direction of the irradiation, and the three Chu Yan who have been waiting for the patrol boat to pass a little faster in the water have been observing through the water!!

"Gollum!!" Just when the other party's patrol speedboat was about fifty meters away from the hiding place of the three people, Chu Yan's shoulder was suddenly slapped by the four-legged snake, and the four-legged snake opened its mouth and almost drank the seawater, the reason was that he was a little nervous, and subconsciously wanted to open his mouth to speak, and the reason why he opened his mouth to speak was that the three motorboats had been fixed under the water, but at this moment, they were slowly floating upward!!

"Damn!!What's going on!!" Chu Yan's gaze fell on the three motorboats, reached out to pull a ghoul, and then pointed to the three motorboats, and the three people immediately dived down, until the bodies of the three people pressed against the motorboat, the motorboat temporarily stopped and continued to float.

The "Boom !!" patrol speedboat galloped past the diving position of Chu Yan and the others, and the diving time of Chu Yan and the four-legged snake and the ghoul had passed for a minute and a half at this time, the ghoul's face had become very ugly, the four-legged snake was slightly better, only Chu Yan still looked smiling, and there was no sign of discomfort!!

"Five... Four... Three... Two... One!" About ten seconds after the patrol speedboat galloped over the heads of Chu Yan and the three of them, Chu Yan raised his hand at the four-legged snake and the ghoul, and then started a five-second countdown, and when the last second countdown ended, Chu Yan gave a thumbs up, signaling that he could surface for ventilation!!

"Whew!!Phew!!!Suffocate Lao Tzu!!" The ghoul was the first to get out of the water, but instead of the kind of movement that came to the surface, it slowly emerged from the water, and then opened his mouth and spit out a mouthful of turbid air that was holding on to his chest and almost suffocated her from internal injuries, and then cursed fiercely.

Beside him, the four-legged snake also got out of the water, looking at the patrol boat that had gone away, it was also a long breath, Chu Yan was the last to drill out of the water, and after taking a deep breath, he had a deeper understanding of the defense of this John's Dole Island.

"This damn John's Dole Island, the sea patrols are so frequent, okay, let's deal with the motorboats right away to make sure they don't surface on their own, and then we'll get out of this damn water!!" Chu Yan took a deep breath after speaking, and the three of them got into the water at the same time, re-fixed the three motorboats, and confirmed that they would not play any more tricks of automatic floating, and then they got out of the water again!!

"Okay, Black Butterfly, throw the rope down!" This time, Chu Yan, the ghoul, and the four-legged snake each had a rope, and climbed up the steep sea cliff of about ten meters with their arms staggered, and then put the three ropes away and joined the three Black Butterflies!!

"Our location is here, the location of the prison is here, according to General Kailo's order, the six of us will be divided into three groups, sneak in from here, here and here, is there a problem?" Black Butterfly saw that everyone was together, and immediately took out the map in the waterproof pocket, turned on the flashlight and began to arrange the next plan!!

"Yes!!And it's a big problem!" This time, it was no one else who spoke, it was Chu Yan!!
