The scientific research institute is very important, Tang Mu let Mr. Program Xian master it, and Tang Mu asked Mr. Program Xian to recruit a group of scientific researchers among the survivors to enter the research inside, and the main research direction is science and technology and cultivation.

Don't look at the program, he is already in his sixties, but his energy is still very strong, he doesn't look like he is in his sixties at all, and the whole person is very flexible, otherwise Tang Mu would not let him take charge of the scientific research institute.

After the end of the world, the lifespan of the evolutionary will become longer with evolution, and the lifespan of the first order and the first order and below will not increase much, but there is no problem in living a long life span in good health, and some people can even live to be more than a hundred years old.

And once the evolutionary enters the second order, then his lifespan will be greatly increased, his lifespan will be doubled, and it is nothing to live two hundred years old, Tang Mu from the memory of the reborn Tang Mu, the world of the reborn Tang Mu, after the end of the world, some second-order evolutionaries have lived to be more than two hundred and ninety years old, and they are definitely very long-lived.

Moreover, after entering the third order, the life span of the evolutionary will increase, and even once the fifth order is reached, at that time, the cultivator will basically not have a limit on his lifespan, and he can live forever.

Therefore, Tang Mu was not worried that the program would be old and unable to manage the scientific research institute.

After the construction of the law building that should be built was completed, a day had passed, and there were only two days left before the territorial catastrophe, at this time, Tang Mu ordered the other survivors to collect and store resources such as wood and stone in the next two days, and at the same time prepared to take advantage of these two days to retreat, to see if he could take this opportunity to use the Heavenly Summoning Book to summon some hole cards.

"Summon!"

Don't dare to delay the time, this time Tang Mu is directly in retreat in the Lord's Mansion, it is absolutely safe here, unless someone can break the Zhenlong Stone in front of the Lord's Mansion, but that will definitely alarm Tang Mu.

Therefore, Tang Mu can summon with peace of mind, and he doesn't need the protection of people, Tang Mu summons directly, which is also the first summoning after the upgrade of the Heavenly Summoning Treasure Book.

"Hope for good luck!"

Looking at the operation of the Heavenly Summoning Treasure Book, Tang Mu prayed in his heart.

The blue sky, like a clear ocean, under the sky, a vast wasteland, full of ancient meaning, on this wasteland, occasionally heard the sound of ghosts crying wolf, absolutely terrifying.

In one part of this wasteland, there is a huge forest, in the forest, ancient trees stand tall, all kinds of ancient trees are extremely tall, not at all comparable to modern forests, and even older than the ancient primeval forest.

In the forest, countless wild beasts are rampant, staging bloody laws of the jungle, countless beasts have died, and countless beasts have risen.

In the midst of such a jungle, there is a cold pool, and next to the cold pool, on top of a small tree that looks like an orange tree but is only an arm's high, there are dozens of thumb-sized fruits sparsely.

At this time, the fruit of this tree was already red, and it seemed to be ripe, and it gave off an infinite and attractive fragrance, and countless wild beasts were attracted by the alluring fragrance of this fruit.

Then a great war broke out, countless beasts fought, and the smell of blood filled the entire forest, startling countless birds.

"What kind of fruit is this, which has caused so many beasts to fight for!"

Tang Mu felt the scene in his mind, and knew that this scene was likely to be the world that the Heavenly Summoning Treasure Book was connected to, and Tang Mu was able to summon some treasures from this world.

When the Heavens Summoning Treasure Book was not upgraded, Tang Mu could only wait and let the Heavens Summoning Treasure Book randomly summon the treasures in the world that were linked, and now, Tang Mu actually couldn't control the summoning of the Heavens Summoning Treasure Book.

But at least, now Tang Mu can sense the scene of the world he wants to summon, although it is not very clear, and the range of sensing is not very large, but it is an improvement.

The only thing that made Tang Mu unhappy was that he still couldn't control the summoning of the Heavenly Summoning Treasure Book now, and could only passively wait for the random summoning of the Heavenly Summoning Treasure Book.

"This little tree looks extraordinary, if only I could summon this little tree away."

Tang Mu saw the extraordinariness of the little tree, and immediately thought greedily, but Tang Mu was just thinking about it, whether he could summon it or not was still unknown, after all, now his summoning control over the Heavenly Summoning Book was zero.

It can only passively accept the random summoning of the Heavenly Summoning Tome.

Then, in Tang Mu's induction, a red light began to appear in the world he felt, this red light was like an aurora, it was very beautiful, and it appeared in this world suddenly, which seemed very magical.

Sensing this red light, Tang Mu didn't have to think about it, as the owner of the Heavenly Summoning Treasure Book, Tang Mu instinctively knew that this was the summoning light emitted by the Heavenly Summoning Treasure Book, and it was the foundation of the Heavenly Summoning Treasure Book to summon otherworldly items.

It's just that the original summoning light was white, but now it has become red, Tang Mu estimated that it was because of the upgrade of the Heavenly Summoning Treasure Book, and Tang Mu sensed that this red summoning light was more powerful than the white summoning light.

With the appearance of this red summoning light, the countless fighting beasts instinctively seemed to sense the danger, and became restless, and some apes raised their heads and roared, as if warning the red summoning light that appeared.

In this regard, Tang Mu was very speechless, Tang Mu's eyes were moving with the movement of the red summoning light at this time, he wanted to see where the red summoning light would fall this time.

"It's better to land on that little tree!"

Being able to cause so many beasts to compete for it, it can be seen that this little tree must be a treasure of heaven and earth, Tang Mu naturally has the most eyes on this little tree, so he kept shouting in his heart: "Fall on that little tree...... Fell on that little tree...... Fall on that little tree......"

Perhaps sensing Tang Mu's shout, the red summoning light slowly fell, and it really fell towards the small tree, seeing this, Tang Mu suddenly had a feeling that his wish had come true, and he had a sense of pleasure that he had gotten what he wanted.

"It really landed on this small tree, could it be that this Heavenly Summoning Treasure Book can really sense my thoughts?"

Tang Mu was very surprised that this red summoning light fell on this small tree, but he was also very surprised, thinking that he would be able to get this unknown little tree immediately, Tang Mu's heart was suddenly full of anticipation.

"I don't know what kind of natural treasure that little tree is, maybe it will be useful to me."

Thinking of this, Tang Mu's heart calmed down, and quietly looked at the red summoning light, as if slowing down the camera, slowly falling towards the small tree, and then the entire red summoning light enveloped the small tree, enveloping the entire small tree, and in an instant, the small tree was wrapped in the red summoning light, and then in a flash, Tang Mu found that his induction came back before he could see the results, and he couldn't sense the existence of that world.
