Meng Lang sat in the back seat of the car, and the warm morning sun shone in through the car window.

After admiring the exotic scenery full of wind and sand for a while, he slowly fell into deep thought.

Recalling the epic war scenes between the immune cells in the body and the influenza virus in the past few days, I can't help but sigh in my heart, sighing at the strength and sophistication of the human immune system.

At this moment, I don't know how many such wars are taking place in the body of every human being on Earth!

Fighting against these powerful immune legions is undoubtedly walking a tightrope in the middle of the cliff, and one mistake is the end of falling into the abyss!

And the team of modified cells in his body that has been devouring cancer cells has not changed much so far.

Originally, Meng Lang wanted to rely on the devouring of these cancer cells so that the modified cells could evolve a camouflage ability similar to that of cancer cells, but at present, it seems that this wish is still far away!

Symptoms such as fever and cough that I exhibited during this human experiment are actually a crisis warning from the immune system to my master!

Warn him that there is an enemy invasion, pay attention to rest or replenish energy, Meng Lang estimated that if there is no immune system, human beings will die happily after getting sick, and the whole process is silent.

Thinking of this, he couldn't help but sigh again!

Cars are speeding down the road.

Soon, a few hours later, he appeared in the parking lot of the Desert Province Airport, and after Meng Lang thanked the driver, he got out of the car and walked into the airport hall. 35xs

He then boarded a flight to Quang Nam Province, where he landed and finally returned to Quang Nam Province.

At this time, it was already evening, and after a whole day of tossing and turning, Meng Lang couldn't care about his tiredness, and after a casual dinner on the street, he went straight home.

After entering the house, he first made a cup of mixed nutrient solution and drank it, and then sat down on the sofa with satisfaction.

After the last acne treatment, nutrients such as glucose, amino acids, vitamins and other nutrients have become one of his usual drinks.

It tasted a little weird, but it was the only way he could find an extra boost of energy at the moment!

However, the successful construction of gastric vascular blockage this time undoubtedly added a powerful nutritional logistics guarantee for the cells in the body.

Of course, this is only half the battle, if the next experiments are also successful.

Then he sketched an image of the photoreceptor cells in his mind and slowly entered a state of inner vision.

Focusing on the blood vessels in his stomach, he nodded with satisfaction until he saw that the blockades in the blood vessels were intact.

In terms of materials, graphene is undoubtedly the best material for building barriers, but at present, Zhang Xiaocuihua has not sent a new batch of graphene, so Meng Lang has no choice but to use human impurities as the main material.

Let's rebuild it later.

He then directed the modified cells that remained in the blood vessels to flow down the bloodstream and into the stomach.

As soon as he entered, he felt as if he had entered a huge swampy planet, and from the microscopic angle of the cells, it was so big that he couldn't see the edge at a glance!

The fog was churning all around, and the glass of mixed nutrient solution that had just been drunk was tumbling inside, and the whole stomach was slowly squirming, like a food blender, stirring and tumbling the food that had been eaten.

Meng Lang felt that if he could hear the sound, it must be like a factory rumbling loud noise.

A large amount of liquid seeped out of the air and dripped onto these foods, causing puffs of white smoke, and hundreds of modified cells couldn't dodge, and they were corroded and melted by these liquids in an instant!

Meng Lang knew that these should be gastric acid, gastric acid is actually diluted hydrochloric acid, its acidity is very high, and it will be secreted in large quantities after eating, which is to promote food digestion and take on the preservative and fermentation of food.

Many foods that are difficult to digest, such as iron, zinc, vitamins, etc., require adequate concentrations of stomach acid for optimal absorption.

The clever thing is that there is a thin layer of mucous membrane that protects the stomach, so these extremely corrosive things cannot damage the stomach.

And the hundreds of modified cells were not so lucky, and they only lasted less than three seconds under the corrosion of these stomach acids, and they were no longer found, leaving only a puddle of liquid.

Stomach acid is actually a double-edged sword, the amount cannot be too much or too little, and it must be controlled within a certain range.

When it is secreted too little or lacking, it can cause indigestion such as bloating and diarrhea, and excessive secretion will invade the mucosa, resulting in complications such as ulcer perforation and bleeding, and affect the aggregation of platelets and the activity of coagulation factors, so that the blood is not easy to coagulate, resulting in bleeding and rebleeding.

The reason why Meng Lang wants to occupy this place is not only to enhance his own digestion ability, but also to enhance the acid resistance of the modified cells!

He watched with interest for a while before directing the remaining modified cells to carefully avoid these stomach acid swamps and go all the way down to the duodenum.

This is the ultimate purpose of his hard work to do free human virus experiments this time.

The duodenum is an organ connected to the stomach, with a length of 2025 and a diameter of about 45, which is the most important part of the entire digestive system.

The stomach above only plays the role of grinding and corroding food, and this is the place where digestion and absorption take place.

All the food eaten is broken down here, converted into glucose, amino acids and other nutrients, and then transported by the various plasma proteins in the blood to provide all the cells with the energy they need!

However, because a small amount of gastric acid will also enter here, the modified cells are not yet able to participate in the digestion and delivery of nutrients.

However, because stomach acid is so corrosive, there will also be bile and pancreatic juice secretion to neutralize these stomach acids.

Therefore, the acidic environment here is much weaker than that of the stomach, which is suitable for cultivating the acid-resistance of modified cells!

What Meng Lang has to do next is also very simple, that is, he constantly sends modified cells here to "send them to death".

As long as any of these modified cells can withstand the acidic environment here for a relatively long time, it is a success!

Then he didn't hesitate anymore, and as soon as his mind turned, these modified cells jumped into these acidic swamps one after another, rolling and swimming in them.

However, it is a pity that this batch of modified cells did not last long at all, only for a few seconds, and they were never seen again.

Meng Lang was not discouraged, he knew that this would be a long-term and slow process of mutation and evolution, and then he continued to command the next batch of modified cells to jump.

In this way, after a period of time, there have been more than 20 waves of "glorious sacrifices" of modified cells!

The number is gradually decreasing, and there are not many modified cells left here before.

Meng Lang groaned for a moment, then stopped, and began to direct these modified cells to absorb the high-energy particles of the universe.

When these cells had enough energy storage, under Meng Lang's thoughts, these transformed cells trembled and began to replicate

Once he had gathered a certain number, he directed the cells to begin to rush into the acidic swamps
