All kinds of weapons fired together.

The bullets rained on the giant rats, and the fast approaching rats were like the waves meeting the hard rocks, which were suddenly frustrated.

But the temporary frustration does not mean that the hungry creatures will retreat. Instead, they charge towards the soldiers on the side of the rock with faster speed and more desperate attitude. The bloody smell of their companions and the pain of bullet shooting in their bodies stimulated them to be extremely crazy. The mutant giant rat with tenacious vitality, if it doesn't hit the key point, needs several or even ten guns in the body to completely lose its action power.

As for death, unless they hit the brain stem or heart, they will fall on the swamp and struggle until the blood runs out.

"Fire with all your strength, machine gunners suppress rats, snipers shoot with precision! If you find their leader, there must be a leader among them. If you find him, as long as you kill the leader of the giant rat, these dogs will disperse immediately! " Little Eric had never met a mutant giant rat, but he knew that underground creatures often had leaders.

Killing the leader is the best way to force back the underground creatures.

of course.

It's not easy.

Because of the poor living environment, the underground creatures are far more cunning than the ground creatures in the case of survival of the fittest.

Lin Dong can clearly sense the existence of the leader of the rat group. Through it, Lin Dong can guess the mutation truth of these giant rats. However, it is impossible for him to tell little Eric the secret. He came here with the intention of making a fortune. How can he put his own money into other people's pockets!

The soldiers shot nervously, but Lin Dong entered a leisurely mode of watching the play.

A rare Hollywood blockbuster!

You don't have to pay for movie tickets!

"Grenades! Come on, they're coming Many soldiers saw that the bullets were gradually unable to hold down, so they quickly took off their grenades, opened the insurance, and then threw them at the tide of the enemy.

"Hell, is this still a mouse?"

"I think these ghosts are stronger than cows!"

"Shoot that leaky fish, it's very fast. Shoot it, shoot it quickly!"

Several places were broken through by rats, which made it difficult for the soldiers to care. Fortunately, Philip and Griffin, these experts, easily killed the fish in the net, so as to maintain the stability of the whole front. With the concerted efforts of all the people, the soldiers insisted on the support of Josiah and gene soldiers. The soldiers and the super elite team work together, and the firepower is super strong. The soldiers' morale is greatly boosted, and they play more and more excellently. However, the mutant giant rat is still unable to break through the soldiers' guns even though it has paid a lot of damage.

Under the powerful interception of modern firearms, the mutant rat group gradually has nearly 10% sacrifice, countless corpses and blood everywhere.

I don't know whether the leader sent the signal or because of fear.

The rats retreated helplessly.

Just like when they came here just now, they quickly retreated into the darkness, and soon disappeared. If it wasn't for the mountain of rat carcasses on the swamp ground and the dense smell of blood, people would even doubt whether this giant mutant rat group had really appeared.

"We've been here so many times, but it's the first time we've met this mutant rat group!" Little Eric felt that everything was not going well. First, there was a big difference between the opening and closing time of the mysterious door. Then there was the attack of underground flagellates. Before he went down the abyss, he was almost driven back by a group of jellyfish like monsters. Now just starting to explore, I have encountered so many troubles, and I don't know what will be ahead of me in the next journey! Unfortunately, the shortest opening time of the mysterious gate was five days later, and there was no return. Otherwise, little Eric would suggest to retreat back to the base site for the time being.

"What about the casualties?" Asked Josiah, frowning.

"Fortunately, the rats didn't break through the defense line. We have no casualties for the time being. However, in just a few minutes, we have consumed one third of our ammunition, and then we continue to go deep, and we don't know if there are the same large group of underground creatures coming. " Little Eric didn't expect that the bullet consumption would be so serious, but at that time, the situation was urgent. If he didn't shoot hard to intercept, I was afraid that the whole team would be completely gnawed by the rats.

"There's a rest cave not far ahead. Our last group left some ammunition there. Although we can't replenish all the ammunition, we can make do with it." Josiah motioned for the team to start at once.

The strong smell of blood will attract more and more powerful underground creatures.

Stay here again.

Life is in danger at any time.

The soldiers quickly removed the tent and moved. Lin Dong ran to the mutant rat carcass and looked at it for a while.

Professor Jeffrey followed him almost every step of the way, gesturing to his subordinates to take a picture, and staring at Lin Dong's face, as if to see something on his face. The female soldier, who is responsible for protecting Lin Dong, nervously takes out her pistol and points to the half dead mutant rats on the ground, fearing that they will turn over and hurt people again.

"What makes them so mutated?" Asked fox.

"I don't know yet." Lin Dong shook his head and did not make a final conclusion: "I suspect there is an almost constant source of pollution or radiation around here. These giant rats can't become like this in one generation or two. They have mutated into this form for thousands of years or even longer

"Can constant radiation keep the variation going?" Big Ivan keenly captured this information, and Professor Jeffrey on the other side also flashed his eyes.

"It's possible in theory, but the source must be strong enough to exist for a long time." Lin Dong smiles.

"Is there no such research in China?" Asked big Ivan tentatively.

"I don't know. At least I don't have such research in my hands. I personally don't hold a highly appreciative attitude towards gene variation. On the contrary, I think that the original human gene is the best. If it mutates, it may gain strength in a short period of time, but it also needs to pay some other price in exchange. This is a result that is not worth the loss. " Lin Dong shook his head.

"The price? Exchange? " Professor Geoffrey asked strangely, "how can I not know what price the gene warrior paid in exchange?"

"It's hard to say that at the moment. If we use our cultivation method, the soldiers with genetic variation will have slower training effect than those without genetic variation. " Lin Dong gave an example with reservation.

"Your Oriental cultivation?" Professor Geoffrey laughs: "I don't think the immortal cultivation method in your legend is of any use. Those are the fantasies of ancient alchemists! Mr. wood, although you have made great achievements in gene, please don't mislead us to the direction of fantasy, OK? Our May Flower Group is very sincere to cooperate with you

He thinks that Oriental cultivation is false.

The existence of fantasy.

even to the extent that.

Professor Geoffrey thinks that Lin Dong is deliberately misleading himself by using illusory things to cover up the genetic truth.

For his idea, Lin Dong is not happy on the surface, but he praises it in his heart. It's too much for you to think like this. This is the result I want! But on the surface, Lin Dong's face sank: "Professor Jeffrey, please let's keep our own opinions."

Little Eric saw that Lin Dong's face was not right, and quickly came forward to apologize: "Mr. wood, we have no malice to you, but we are too eager for your achievements in genetics!"

"Professor Jeffrey, don't you think Mr. wood is just a nerd with no power to bind a chicken?" Big Ivan can't help but sneer.

"Isn't Mr. wood's strength based on his genetic theory?" Professor Jeffrey did not believe that Lin Dong's "Kung Fu" was really practiced. In fact, not only he, but also Philip and fox have the same doubts. Ordinary college students can't be so powerful. Lin Dong must have injected the best gene medicine, maybe the golden gene medicine that never appeared.

It's a little different from Professor Jeffrey.

Philip and Fox also think that part of Lindong's strength is really trained.

For Jeffrey, the professor, the Oriental style of cultivation is ridiculous and an alchemist's fantasy. But for them, as super strong men, the Oriental style of cultivation is a real thing.

It's a kind of "Qi" that is more powerful than blood energy. It's a special energy that Westerners can't practice, and only Oriental people's physique can practice successfully.

Fox and Philip even suspect that because of his cultivation, Lin Dong opened his brain and God's forbidden area, so that he could get far more achievements than the times in genetics, and his body was also greatly strengthened. Only by strengthening both the brain and the body, can the ordinary college students in the past become Mr. wood, who is famous all over the world today.

"Hey, you are not qualified as a novice apprentice. Shut up immediately!" The Griffin was furious when he heard that Professor Geoffrey was talking about his favorite God.

"I think you're jealous, too!" Big Ivan added fuel to the fire.

"It's you who should shut up. I'm also an authority, but I'm not as good as Mr. wood. You're not what I should talk about at all, OK?" Professor Jeffrey gave a cold smile. If it wasn't for Lin Dong's 100% success rate in gene experiment, he would not be convinced. What are Griffins and big Ivan? A warrior who only knows brute force, a spy leader of the Maoxiong Kingdom, do you know what science is? How ridiculous!

"It's OK to have a controversial view of things. I'm not a dictator." Lin Dong said with a smile: "however, we'd better leave the controversial things to go out. Now it's time for us to go. In the dark, I feel a lot of things are approaching..."

"Let's go!" Little Eric's heart immediately became nervous.

In the past, he was a little dismissive of Lin Dong, and thought that no matter how much he could fight, it was almost the same as himself.

But after a period of time, he found that he and the other party are not at the same level.

Whenever danger comes up, the other party is always the first to give a warning, long before he enters the abyss and has "rich experience" for many times. Moreover, this gifted scientist, who has never entered the underground world, is extremely accurate in observing and judging things. Compared with him, I'm really like a novice apprentice. No, maybe even a novice apprentice is not qualified!

They found what Josiah called the cave.

That cave is very small.

To be exact, it's not a cave. At most, it's a residence drilled out of a huge rock gap by a group of underground creatures, and then cleaned up by humans to obtain a temporary resting place.

"Here!" As Lin Dong approached the cave, he frowned.

"Is there anything wrong with this cave?" Fox is best at looking at people's faces.

"There's a strange smell. Maybe there have been powerful creatures before. In other words, there used to be highly polluted organisms here. If we can find them, maybe we can better find the source of radiation pollution! " After observing the cave, Lin Dong asked Josiah, "have you ever found any bones or huge bodies when you cleaned them up before?"

"No!" Josiah shook his head: "this cave is not big. Has there ever been a huge creature?"

"It should have appeared, but most of the traces have been destroyed. What a pity!" Lin Dong watched the cave wall with a flashlight for a while, and finally shook his head.

Everybody looks at Josiah.

Everyone suspected that this guy was lying.

It must have been discovered before. Josiah moved it back to the base, but because it was too secret, he chose to hide it.

Josiah's mouth is closed tightly. It's impossible to force him to speak out. For people like Josiah, the interests of the rice nation must be above everything else. However, he did not say that Lin Dong had a way.

"Although there is no trace, there is still a little residual taste. Maybe we can find a way to trace and find the real source of radiation pollution!" When Lin Dong said this, Josiah, Eric and Jeffrey were very complicated. To be honest, they don't want Lin Dong to find such an important source of radiation pollution that can make organisms mutate before he is completely under his command. But without Mr. wood, how can we find the pollution source that we don't know where?
