The tide of the sea of ??death has subsided. Although the flood has not receded, there are no wind and waves. With the strong outer wall and huge iron gate of the base, the flood outside cannot enter. Lin Feng and the people can feel at ease for the time being Rest, especially Lin Feng, he has consumed a lot of energy to deal with monsters, and he needs to replenish his power of death while taking advantage of the tide of the sea of ??death.

On the other side of the mainland world, since Lin Feng broke the seal in the underground world and caused the blood pool to erupt, the underground world has become another desperate world, with highly poisonous blood pools rushing through the underground world. The people were submerged by the bloody pool that suddenly appeared, and the deadly toxins and people without water were all killed. Only a small number of people, such as those in the martial arts academy, sensed the destruction of the seal in advance, and died before the blood pool erupted. Prepared for protection, only the Martial Academy was not flooded by the pool of blood.

The distance between Agula's heart at the entrance of the underground world and the blood pool is less than half a meter, and the people guarding the entrance are completely unmoved, as if these things have nothing to do with them, their duty Just guard the entrance.

The eruption of the blood pool has stopped, and the distance between the blood pool and the heart is even smaller. It seems that only a small wave can make them fully contact. At present, the people of the martial arts academy are desperately resisting in the protective cover. It won't be long before the cover is replaced, and the toxins in the blood pool can also have an effect on energy, so although the protective cover is not damaged now, the protective effect is getting smaller and smaller.

"Dean, the protective shield is about to die, what should we do?"

The disciples of the Martial Academy have already started to panic. At the beginning, they relied on their own protection layer and were not afraid at all, nor did they worry about the life and death of the outsiders. Nowadays, people in the underground world have become so indifferent, they only care about themselves.

"The Martial Academy is so big that the energy protection layer can't last long. Our hope is to leave the underground world as soon as possible, but the guards at the entrance of the underground world are hard to deal with."

The person who answered the question was the newly appointed dean of the Martial Academy, that is, Ru Fen who directly participated in the zombie experiment. He advocated that all human beings in the underground world return to the above-ground world, and to survive well in the above-ground world, one must not be afraid of zombies. Therefore, he and the people in the underground world conducted a secret experiment with the purpose of making the humans in the underground world not afraid of the virus of zombies, so they used the people in the underground world for the experiment, and the energy of the orcs was the key.

The current situation of the Martial Academy can't last long. The dean can only deal with one of the four guardians. As for the others, the dean actually didn't think about taking them away. It's up to his own ability to leave. The situation no longer allows me to be a good person. In fact, they are not good people.

"Go to the warehouse to find some wooden boards, and tie the wooden boards together. Didn't the book say that there is such a thing as a 'boat'? Let's make one like this."

The people of the Martial Academy are now at a critical juncture. They don't know how the blood pool outside will affect them, but they know that if they don't know water, they will definitely be drowned. opportunity to take advantage of.

Objects immersed in liquid are buoyant force when they are lifted up by liquid. People in Wuyuan want to build a boat because they know the principle of buoyancy.

In the last days, although the technology in the above-ground world is the most developed, the underground world has been sealed underground since thousands of years ago. They don't know about technology, and they don't know the relevant principles and concepts. I get what I want from experience, even the wooden boat I want to make now is not something I understand, I just know that this thing can save lives.

Under the current situation, there are only dozens of people with slightly higher energy left in the martial arts academy. They are usually very prestigious in the underground world, but in this scene in front of them, they are like a group of cowards. Ideas can only be acted on by other people's arrangements.

The cause of buoyancy can be analyzed with a cube submerged in liquid. The object is a fully immersed object, which is under the pressure of liquid in all directions, and increases with the increase of depth. So the front and back, left and right, upper and lower faces of this regular cube are all under the pressure of the liquid. Because the forces acting on the left and right sides correspond to each other, have equal areas, and are at the same depth in the liquid, the pressures on the two sides are equal in magnitude and opposite in direction, and the two forces balance each other. In the same way, the pressures acting on the front and rear sides also balance each other. However, because the depths of the upper and lower surfaces in the liquid are different, the pressures they receive are also different. The pressure on the top is small, the pressure on the bottom is strong, and the upward pressure on the bottom is greater than the downward pressure on the top. The pressure difference between the liquid and the object is the buoyancy force of the liquid on the object. This force is equal to the gravity of the liquid displaced by the object.

After all, the people in the Martial Arts Academy are practitioners, and their abilities are all kinds of strange. For things like making wooden boats, they follow the methods and graphics recorded in the book, use each person's energy to combine a small part, and soon, a wooden boat can be made. Well, at this time, the protective layer is about to reach its limit.

Because the wooden boat is very small, it can only accommodate one person, and there are still dozens of disciples left in the martial arts academy. When the wooden boat was being made just now, the head dean had already thought of this problem, but the protective layer was about to break, so he also I don't have time to direct everyone to make so many wooden boats, out of selfishness, the dean doesn't care about anyone except his own life, and now the dean has the strongest energy among all the people, no one can push him off the boat.

When the dean sat and put it on, no one else knew what to do. Although no one moved, everyone knew what was going on in their hearts. The strong survived, and only those who survived to the end were eligible to sit. On board, a war could soon break out.

Just when everyone was about to attack each other, a person stepped onto the boat delicately from the crowd and sat down safely. This person was known by the dean, and he was Fan Bin who was used to lure Lin Feng to show up.

But everyone didn't know that Fan Bin had actually been pushed into the pit by Lin Feng, and had crossed the space boundary to reach the level of a zombie. Now Fan Bin, everyone thought he was still that ordinary disciple.

"You deserve to be on this boat too?"

The dean was very dissatisfied with Fan Bin's ignoring attitude, and just took this opportunity to kill him to silence him, so as not to expose the experiment, but Fan Bin just glanced at him, and then nothing happened.
