Because there are more formation materials harvested, some portal equipment can be made when there is nothing to do, and the application has become frequent, for example, the six pots of spirit grass have been embedded with portals, so that in many cases, even if the spirit grass is placed in the storage space, it can still be cultivated.

In addition, in order to make the portal stronger, he still tried to make the portal with super alloy as the base material, and even tried to remove the substance in the middle of the portal, and directly made the portal into a circle instead of a large mirror.

After obtaining the portal technology over the years, many technical difficulties have been overcome, and the reason why there was no large-scale experiment in the past was indeed because there were no formation materials, but now it seems that he became rich overnight and became a local tyrant.

The formation material reserve has exceeded forty kilograms, and there should be some material harvest for about half a month before the return, and there will be a little unexpected surprise from time to time, which feels really cool.

Now basically, every day when I go to the palace, I will have one or two kilograms of formation materials, and occasionally I can find some precious medicinal materials rich in spiritual energy, and even a few pieces of mineral jade with special energy fluctuations.

Of course, in return, Zhu Houxi has also obtained many portals of different sizes, and has even used those micro teleportations in the construction of communication networks in important state capitals across the country.

Of course, the people in Phoenix Villa also got a pair of magical 'golden steel rings' and played many different tricks.

And Zhang Tiancheng himself, while stocking up on various means to finally kill the black python, and at the same time making a formation on flexible materials.

If this technology is mature, then it is completely possible to make a big lasso, put it on the giant python that is extremely strong in defense, and then borrow the rules of space to cut the monster in minutes.

It's a pity that this technical difficulty is really not ordinary, at least before the return, it is basically impossible to complete, and after another failed experiment, I finally gave up the attempt to continue to improve the portal.

A teleporter left the secret room, but found that Na Lin and Qu Feiyan were exercising, using the golden steel ring portal to reflect the attack technique.

I saw that Na Lin started to bend her fingers left and right, and the steel ball projectiles were like pistol bullets fired, but Qu Feiyan quickly waved this arm and used the gold steel ring in his hand to trap the projectile.

The projectile was directly reflected back the moment it touched the portal, but Qu Feiyan didn't receive a trace of impact, but Na Lin was a little confused by the projectiles that came back from the counterattack, and quickly pulled out her thin sword and played a set of Dugu Nine Swords' arrow-breaking style, splitting those projectiles.

"Xiao Feifei, how did you do it, the portal can not only divert attacks, but also directly rebound attacks?" Narin, who couldn't figure it out, put away her sword and asked curiously.

"Senior sister, why is your master here, you should invite the master." Qu Feiyan said triumphantly.

"The little girl is smart, she understands the truth so quickly!" touched Qu Feiyan's head, but it made this proud little girl stunned.

"Could it be that Master also knows this little trick?"

"I don't know this, what else can I do with your master?"

"Then why didn't you tell us earlier?"

"It's about developing your creativity and self-thinking skills." Regarding Zhang Tiancheng's words, Qu Feiyan could only be speechless, but she always felt that this master was dazzled by the big and small goblins in the National Teacher's Mansion and forgot about it.

"Narin, you turn one of these two portals upside down, and then overlap them together, and you can form a teleportation array that completely reflects all attacks." He took a pair of portals from Narin, reversed one of them and put them back together, then took out the dagger and stabbed it through the activated portal, but it was up to the dagger that had been stabbed through the space-time transformation.

No matter what, the force can't penetrate a bit, and what's even more amazing is that the force is as strong as ten kilograms, but the hand holding the portal can't feel a trace at all.

The rules of spatial transformation are really magical

"It's amazing, it's an invincible defense."

"This kind of reflex attack does not theoretically have any upper limit of defense, as long as the portal itself is not damaged, even the sword qi cast by a master at the peak of the Heavenly and Human Realm will be completely reflected back."

"So if you hold this baby, you're invincible!"

"Of course you can't be invincible, there is a big flaw in this defense, although this portal itself is made of Xuantie, but once it is attacked, it will definitely be damaged, and Xuantie can't block the attack of the supreme master qi sword."

"Well, it's not too early, I have to go to the National Teacher's Mansion." I looked at the sun that was about to go up the mountain, and the chat ended.

"Go find those goblins again."

"If you want to talk about goblins, you're the real goblin." knocked Qu Feiyan's head and disappeared in an instant.

“…… Senior Sister Nalin, why don't you say a word about this kind of thing? ”

"What should I say?"

"At least it means that you are a little jealous, otherwise Master wouldn't know how much you care about him."

"I'm not jealous, the adult may be about to leave this world, as long as he can be happy."

“…… How is this possible, just like Master, he can't die if he lives for a few hundred years! ”

"It's not that adults will die, it's just that if they leave, they will disappear as they did sixty years ago."

"And what do you do?"

"Of course, when the adults come to pick me up, I have a feeling that the adults will come to pick me up."

"That's good, that's good, let's continue to practice swords." As soon as he heard that Zhang Tiancheng would come back, Qu Feiyan was also convinced.

Although I have only been in contact with this master for more than a month, I like it very much, of course, not the kind of love that men and women love, but a kind of love for my father and brother.

……

It was another sunny day, and at the moment of sunrise, Zhang Tiancheng appeared in the palace as scheduled, and with Zhu Houzhao, who had been waiting for a long time, he went to the highest point of the Forbidden City lightly.

Facing the east, he sat cross-legged, ready to absorb the power of the rising sun, and by the way, help Zhu Houzhao complete the last step of the 100-day foundation building.

As for why you want to come here to practice qi, it is because there are many wishes similar to the power of faith gathered here, and the effect of practicing qi cultivation under this energy will be much better. (Willpower is a kind of intelligent creature, and the emotional energy effect is similar to that of faith)

Of course, those wills seem to be of great benefit to the restoration of Qiankun Ding, so recently, I have brought Zhu Houzhao here every day to practice qi.

Feeling a lot of gazes, his divine sense moved slightly, and the many portals embedded in the Northern Netherworld suit also opened, and in an instant, layers of colorful glow directly bloomed on his body.

The palace maids and eunuchs who saw this scene from afar, as well as those concubines, and even the queen mother, couldn't help but pray silently with their palms, making that wish power much stronger.

Of course, this is the result that Zhang Tiancheng wants, in order to improve some qi training effects, and repair that Qiankun Ding as soon as possible, it is still necessary to pretend to be a ghost once in a while.

In fact, some of these glows were transmitted by the connected Qiankun Ding Portal, some were transmitted from the six spirit grasses, and some of the glows were simply diffracted by LED lights.

However, although it is a disguise, no one can see through it, even if the masters of the Heavenly and Human Realm or even the Jindan Period find out, they will avoid it from afar, because that Qiankun Ding is also a genuine super baby, although it is broken, but the coercion revealed is still very scary.

Another side effect is, of course, even if Zhu Houzhao sees this situation, some careful thoughts will disappear, and subtly, he must not have any bad thoughts about this immortal, otherwise he will definitely be punished by God.

Then it is to send rare treasures to the National Teacher's Mansion every three or five times, plus send all kinds of little beauties from time to time, and there are countless rare treasures in the current National Teacher's Mansion, and the little girls are about to form a reinforced platoon.

obviously didn't do anything, but it gave people the impression of being greedy for money and lustful.

The reason for this is because he asked the imperial court to help collect formation materials, as well as various elixirs, and also tried to collect jade rich in spiritual power that may exist, coupled with his habitual attitude towards the little girl has always been very good, so it caused quite a serious misunderstanding.

The sunrise finally came, and the colorful glow on Zhang Tiancheng's body in an instant also became eclipsed, an extremely active vitality appeared in the air, and the originally calm wish power also became active.

Stimulated by that huge will, Qiankun Ding released an extremely huge traction force, and the energy within a radius of more than ten kilometers was pulled, and it was not only gathered from afar.

Zhu Houzhao, who was sitting next to Zhang Tiancheng and practicing qi, also gained some benefits, and after more than two months of hard work, he finally succeeded in completing the hundred-day foundation building that he had to go through today, and a wisp of Northern Darkness True Qi began to run slowly in the meridians.

In the future, as long as you insist on practicing Qi for half an hour every morning and evening, not to mention how much you have achieved, but health and longevity are certain, and there is no need to think about the realm of heaven and man.

Although this kid's talent is not bad, it's just that as an emperor, he is surrounded by a large group of beauties all day long, and it is really difficult to hold on.

At the end of more than ten minutes of Qi practice, the Northern Darkness True Qi returned to the Qi Sea and completed the harvest.

"Master, I am done, I am done." Feeling the extremely active trace of the Northern Darkness True Qi in his body, Zhu Houzhao was extremely excited.

"Calm, calm, there are still many people watching, you are His Majesty the Emperor!"

"Yes, thank you for your teaching."

"Don't be so polite, but although your foundation has been laid, you still have to practice diligently in the future, at least once a day."

"That's a must, although there is no hope of achieving the realm of heaven and man, but I must become a super master, so as not to weaken the prestige of the master."

After getting along with Zhang Tiancheng for a while, Zhu Houzhao unconsciously learned Zhang Tiancheng's way of speaking.

"As an emperor, there is no need to be a master, just train more master subordinates."

"Actually, I prefer to be a general, but unfortunately my father is only one of my sons."

"You are content, by the way, I heard that Sister Li Feng is pregnant?"

"Yes, yes, thank you Master's magic medicine for letting me go to that hidden disease."
