In the main hall of the saint's ruins.

On the altar, underneath the first box that had been opened, a band of light slowly stretched out and moved towards the second box. "Does that mean the recuperation time between rounds?" Looking at this slow-moving band of light, it should take about half an hour to connect to the second box.

And there were no casualties in the battle that the robot legion below had just ended, but the energy consumption was about thirty percent. And in order to increase the endurance of the robots, Li Nan and they have also done all kinds of measures, these robots after the battle, they have returned to the airborne warehouse, but there are charging equipment inside, which can recharge these robots. At the same time, Li Nan once again opened a door of space in the air, and then one after another, a total of 100 battlecruisers floated above the tree people to assist in the defense of the altar.

After about five minutes, the robot was recharged, and it came out of the airborne compartment with a huge container-like box. Then place these boxes in front to form a temporary defensive front, and at the same time continue to build fortifications, in less than ten minutes, tens of thousands of robots have built an alloy wall to enclose Li Nan and their location in the middle, and at the same time bury those metal discs taken from the Romance of the Three Kingdoms world according to the pattern of the formation, after a period of tossing, a defensive formation has been built by the robot legion, when the pale golden shield wraps the entire position, the time has passed about twenty-five minutes, According to Li Nan's previous calculations, there were only less than five minutes left.

"Have you really learned this defensive formation?" Looking at this shield, Zheng Zhe, who was in a stunned state, even dropped the cigarette he was smoking on the ground: "But are these turrets really useful?" Why do I think this position is not very reliable except for the defensive formation? ”

A large number of metal boxes the size of containers are piled up on top of each other, and it is not very reliable to think about it, is this defense really passable? Then there is a platform every fifty meters above the wall, and an automatic turret is fixed on it, but looking at the muzzles of those cannons, it seems that they are only about five inches in caliber, to deal with the test set by the saint, are these automatic turrets really reliable?

Listening to Zheng Zha's question, Li Nan shrugged his shoulders, and then said: "This is also something that can't be helped, thirty minutes is too short, even if we can't set up a more advanced defense, but don't worry, after all, there is a defensive formation to support, as long as we block the second wave, we will have more time to strengthen the fortifications, so that our position will become stronger and stronger, of course, the premise is not to let the enemy break through." ”

As the minutes ticked by, the thirty minutes had expired, and the light band was connected to the second box, which began to glow. And the main hall has also begun to change, the big pits that were blasted out when the stone statues attacked before were automatically filled, and the entire hall was restored as before, but the defensive position made by the Zhongzhou team while taking advantage of the gap was left, and it seems that this behavior is allowed.

However, at this time, Wang Xia's face was not very good: "The mines I laid down just now were wiped out, and when I restored the ground, I lost the sense of those mines at the same time." ”

"......" Everyone was speechless, but although the mines were eliminated, the metal discs that were buried as nodes of the formation were retained, so the entire position was still protected by a pale golden shield.

Li Nan circled the back of his head, and then said, "Could it be that these mines were eliminated because they were placed outside the position?" With that alloy wall as the boundary, the positions of the two sides are divided, and all traps outside the position will be wiped out, and the next time you try to lay some mines in the position, too. ”

As soon as Li Nan's words fell, the floor of the main hall changed again, and the ground outside the alloy wall suddenly turned into a choppy sea. The robot standing on the alloy wall tried to throw a detector into the water, and the result of the analysis was 100% pure earth's seawater, and the depth detector had a detection range of two kilometers, but it did not detect the location of the seabed.

"Everything outside our position has been replaced, so Wang Xia's mines will disappear. But this time the battlefield is the sea, and this is Li Nan's home field. Bruce said as he controlled the probe's operation.

Li Nan waved his hand, and then said: "Don't say it, now my ship mother is either fusing the advanced fifth order or preparing to advance to the fifth order, there is no spare combat power at all, and it is impossible for me to let those elementary school students do such dangerous things." ”

At this moment, a large amount of seawater rose from the surface of the sea, and then these seawater gathered together to form a two-hundred-meter-high giant, and the number of stone statues just now was one hundred in each direction.

"How do you fight this?" Zheng Zhe was already sweating profusely at this time. Can you fight an enemy made up of pure sea water on this kind of sea? This situation is to tell everyone that even if these giants are scattered, they can be condensed from the new surface of the sea, and they have just been condensed in front of everyone.

No one answered Zheng Zhe, but Li Nan was obviously a doer, and at this time, the fixed turrets on the platform above the alloy wall turned one after another, aiming at the giants composed of seawater, and then a large number of orange beams shot at the giants standing on the sea. The cannons are powered by small fusion cells beneath the turret, and they are a weakened version inspired by the solar ray guns on the spear of Arden, but these are very hot fusion particle beams, each beam of light can evaporate a large hole about ten meters in diameter in the sea giant.

However, this kind of damage is nothing to the seawater giant, the evaporated part is replenished by the new seawater in less than five seconds, even if some of them are hit by multiple beams and cause the whole person to fall apart, but the next moment it is condensed from the sea intact again.

"Sure enough, it didn't work at all." Looking at the situation on the sea, Xiao Honglu also frowned and said: "Although it is expected that this kind of energy attack is ineffective, the composition of these sea giants is too strange, generally this elemental creature should have a core, and the more powerful the elemental creature, the greater the core." Even if it is hidden in the body, it is impossible not to feel it, how does the sea water condense without a core? Where does the energy advantage that composes them come from? In the process of speaking, another handful of hair was pulled out by himself, saying that Xiao Honglu has not been bald for so many years, Li Nan is very curious that he uses that brand of shampoo.

And after the attack of the fort, those sea giants also began to counterattack, different from the previous stone statues of the physics department, these sea giants were obviously of the law system, and when they counterattacked, they condensed a column of water with a diameter of 100 meters from the sea and shot towards the central position. However, these thick columns of water were blocked by the pale golden shield.

looked at the ripples on the shield, but in the end it was completely resisted, and everyone breathed a sigh of relief. But this is only the first wave of attacks, how many waves can this shield withstand? However, there are a large number of energy stones piled up in the formation, and there is basically no need to worry about it until all the energy stones are consumed, and the wave of attacks just now did not even consume one percent of the energy stones. The main reason is that the heaven and earth aura in this hall is very huge, and those energy stones can automatically absorb the heaven and earth aura to strengthen the strength of the shield and offset the enemy's attack after the energy is activated.

However, it is obviously impossible to pass the test just by defending, but the Zhongzhou team is not helpless against these sea giants, several of them want to speak, but they are pressed down by Li Nan: "It's still early to use the power of the fifth order, and now it's only the second test, and there are still six behind, so if you want to rely on the artifact to clear the customs, let's go down and take a look first." ”

As Li Nan said, it was Ming Yanwei who planned to stand up, Qi Tengyi, Bawang and Cheng Xiao, all of whom had artifact-level things in their hands, and obviously felt that the artifact in their hands could deal with these seawater giants. However, as Li Nan said, it is only the second test, and if the artifact is used first, the subsequent test is estimated to be even harder.

If they don't use the power of the artifact, these people also shook their heads, after all, the abilities of these sea giants are also very headaches. But at this moment, Zhan Lan began to chant the spell in a low voice, it seemed that she was ready to give it a try. Li Nan was also very curious about the spells she was going to use, after all, most of Zhan Lan's spells at this time were already able to be instantaneous, and the ones that needed to be chanted were basically divine spells above the demigod level.

And with Zhan Lan's spell, everyone felt that the water element in this space was more active, could it be that Zhan Lan wanted to use the magic of the water system on these sea giants? And the next moment, Zhan Lan's magic was also completed, a large amount of magic power poured out of her body, and then as Zhan Lan's incantation was completed, a circular blue light spread outward from the edge of the city wall, and where the blue light passed, the turbulent waves had not yet instantly formed a layer of thick ice of more than fifty meters. As the blue light spread outward, the ice condensed rapidly in the direction of the sea giant.

At this time, a large range of frost novas, and the range and power increased a lot under the condition that Zhan Lan infused a large amount of mana, and at this time, the entire sea surface was completely frozen, including the four hundred sea giants who had been standing on the surface of the sea.

Zhan Lan sighed softly, and then said with a smile: "Since there is no way to evaporate them, let's freeze them all, can this be considered a pass?" ”

"This method obviously doesn't work." It was Li Nan who spoke: "You see that the second box here is also completely unresponsive, if it can be passed, it should be opened like the first box." And now this box has no reaction at all, which means that your method is not passed, those sea giants are just frozen, but they are not defeated at all. ”

At this moment, a large amount of water mist suddenly appeared on the frozen sea, and the temperature around it began to rise, which was obviously not a normal method. And as the temperature increased, a large number of cracks appeared from the ice, and now the outside of Li Nan's position was completely shrouded in dense fog, although the shield could block the dense fog, but the situation outside was not very clear.

"The ice is melting fast, and damn the water is still able to control the temperature of the sea." Zhan Lan scolded in a low voice, and at the same time, he could hear the sound of the ice in the distance constantly breaking, obviously just as Li Nan said, these sea giant tiles were not defeated, but simply melted these solid ice by controlling the temperature in the water.

Time passed like this, minute by minute, and ten minutes later, Zhan Lan had already felt that the ice had all melted, and the thick water mist had also begun to be quickly sent out of space by the space's air dispersion system, at this time, the water mist had begun to slowly become thinner, but everyone still couldn't see the sea giant in the distance, and there was obviously an additional ability to block mental power in these water mist, which could greatly reduce the effect of mental power scanning. At this time, the sea giants dozens of kilometers away could not be seen at all.

At this moment, the second box suddenly shone brightly, and then the lid on the top of the box slowly opened.

Cleared the customs, and suddenly cleared the customs without them knowing anything. "What the hell is going on? Who made the shot? Could it be that Zhan Lan's spell succeeded? Zheng Zha was completely stunned at this time: "Li Nan, what did you do?" How? ”

Although Zheng Zhe didn't know what was going on, it was obvious that Li Nan's smiling appearance seemed to be what he had done.

And Li Nan didn't sell it, just said with a smile: "I just opened a spatial door on the sea that leads to the outer sea of my town guard mansion space." The seawater there has completely turned into a high concentration of deep-sea energy seawater under the pollution of the two deep-sea habitats. Then the seawater full of deep-sea energy flows out through the space gate, and then quickly pollutes the seawater in this space. Although this space is very large, the sea water here is not living water, so in just over ten minutes, this sea surface has been polluted by deep-sea energy. And these giants made of seawater were apparently assimilated into deep-sea creatures in the process. So after these sea giants turned into deep-sea creatures, the formation had already changed to our side, so they were defeated. ”

With Li Nan's words, the water mist has been completely cleared, and the four hundred sea giants have disappeared at the same time, and the sea surface has completely recovered to the same ground as before.
